1 is a diagram illustrating a sensor information management system according to an embodiment of the present invention.

Referring to FIG. 1, the sensor information management system may include a mobile terminal 100 and a server 200.

The portable terminal 100 may continuously collect sensor information through a sensor unit (not shown) including at least one sensor, and utilize the collected sensor information. For example, the portable terminal 100 may continuously collect at least one of the surrounding environment information and the user status information (hereinafter, sensor information) through a plurality of sensors. Thereafter, the portable terminal 100 may analyze the collected sensor information and provide an alarm (e.g., an alarm for a health risk situation) to the surrounding environment when the predetermined alarm condition is satisfied. At this time, the portable terminal 100 may provide the alarm by analyzing sensor information collected for a predetermined period of time. In addition, the portable terminal 100 may calculate the correction value of the sensor through the collected sensor information, and correct the sensing value using the calculated correction value to provide an accurate sensing value.

The mobile terminal 100 according to the present invention may include a main processor (e.g., a CPU (Central Processing Unit), an AP (Application Processor), etc.) for controlling overall operation, a low power processor Controller Unit, and MPU (Micro Processor Unit)). This is for continuously collecting the sensor information by minimizing the current consumption of the portable terminal 100. That is, the portable terminal 100 according to the present invention maintains a main processor (hereinafter, referred to as a main controller) having a relatively high current consumption in a sleep state and transmits the sensor information Can be continuously collected.

In the sleep state, the portable terminal 100 stores the collected sensor information in an internal memory (hereinafter referred to as a sub-storage unit) included in the sub-control unit. When the wireless terminal 100 is in a wake-up state, Lt; / RTI > Meanwhile, when the storage space of the sub storage unit is insufficient in the sleep state, the sub control unit may wake up the main control unit, and move the sensor information stored in the sub storage unit to the main storage unit and store the sensor information. Alternatively, when the storage space of the sub-storage unit is insufficient, the mobile terminal 100 may delete the sensor information stored in the sub-storage unit the oldest stored in the sub-storage unit and store the collected sensor information in the sub-storage unit have.

The portable terminal 100 may analyze the collected sensor information and provide an alarm when the predetermined alarm condition is satisfied. For example, the alarm condition may be a reference condition for determining whether the user's health condition deteriorates, whether the user is in a dangerous environment, or an environment that may adversely affect the user's health. The alarm condition may include environmental information such as temperature, humidity, air pressure, ultraviolet rays, radioactivity, carbon dioxide, environmentally harmful substances, or user state information such as movement, body temperature, electrocardiogram, blood pressure, For example, the alarm condition may include a hypothermic induction environment in which a temperature below a certain level (for example, 0 degrees Celsius or less) is maintained for a certain period of time (for example, one hour), an environment in which a difference between a maximum temperature and a minimum temperature The air conditioner inducing environment in which the induced temperature and the difference in temperature between the outside and the outside are maintained at a constant value (for example, 8 degrees) or more for a certain period of time (for example, two hours), an average motion amount per day / week / month / year, can do. The alarm condition may be classified into a first alarm condition and a second alarm condition.

The first alarm condition is stored in a sub-storage unit, and is used when an alarm is notified by the sub-control unit. The first alarm condition is a reference condition for sensing information collected over a relatively short period (e.g., several minutes to several hours). This is due to performance limitations of the sub-controller driven by low power. For example, the first alarm condition may include a hypothermia-inducing environment, an air-conditioner-inducing environment, and an ultraviolet ray exposure dose.

The second alarm condition is stored in the main storage unit and used for alarm notification by the main control unit. The second alarm condition is a reference condition for sensing information collected over a relatively long period (e.g., a day or a month). For example, the second alarm condition may include a daily / weekly / monthly average movement amount.

The portable terminal 100 may provide an alarm by outputting a warning message indicating a user's health risk and outputting a warning sound. Alternatively, the portable terminal 100 may provide an alarm by transmitting an emergency call or emergency message to a predetermined contact (emergency rescue party, doctor, friend, etc.).

The portable terminal 100 may correct the measurement error of the sensor based on the collected sensor information. For example, the mobile terminal 100 may check the change of the sensor value based on the collected sensor information, calculate the compensation value by changing the sensor value, and measure the sensor using the calculated compensation value The error can be corrected.

Also, the portable terminal 100 may control a peripheral device (e.g., an air conditioner, a heater, a humidifier, a boiler, etc.) connected to a wireless (e.g. For example, when the indoor temperature is maintained at 26 degrees Celsius or less for 1 hour or more in summer, the portable terminal 100 increases the room temperature by controlling the air conditioner. If the indoor temperature is maintained at 30 degrees Celsius or more for 1 hour or more, It is possible to reduce the room temperature. Alternatively, if the room temperature is maintained at 18 degrees Celsius or less for 1 hour or more in winter, the portable terminal 100 increases the room temperature by controlling the temperature of the heater or the boiler. If the room temperature is maintained at 23 degrees Celsius or more for 1 hour or more The heater or the boiler can be controlled to reduce the room temperature. Similarly, the portable terminal 100 can control the humidifier to properly maintain the humidity.

The portable terminal 100 may transmit the collected sensor information to the predetermined server 200 and receive the alarm message from the server 200. Alternatively, the portable terminal 100 may receive an alarm condition optimized according to the health state of the user from the server 200, and update the pre-stored alarm condition.

The server 200 receives and stores the sensor information, analyzes the sensor information, and provides the analysis result to the portable terminal 100. In detail, the server 200 receives and stores sensor information from the portable terminal 100 at regular intervals. The server 200 analyzes the stored sensor information and generates an alarm message and transmits the alarm message to the portable terminal 100 when the predetermined third alarm condition is satisfied. For example, when the present invention is applied to healthcare, the server 200 may be a server of a hospital designated by a user, a healthcare center operated by a governmental institution, etc., and the alarm message may include medical information, Method, near hospital or pharmacy location, referral exercise, referral food, warning message, and the like.

In addition, the server 200 stores the collected sensor information in a database (DB) for each user, and stores the collected alarm information in a database based on the user-specific DB based on alarm conditions (first alarm condition and second alarm condition And provides the generated information to the portable terminal 100. On the other hand, in the case of a patient requiring continuous management, the doctor in charge can check the sensor information of the patient stored in the server 200, and transmit an alarm message when an action is required.

2 is a block diagram schematically illustrating a configuration of a mobile terminal according to an embodiment of the present invention.

2, the portable terminal 100 includes a main control unit 110, a sub control unit 140, a display unit 130, a main storage unit 120, a wireless communication unit 150, An audio processing unit 160, and a sensor unit 170. [ The sub-control unit 140 may include a sub-storage unit 141.

The wireless communication unit 150 supports a wireless communication function of the portable terminal 100 and may include a mobile communication module when the portable terminal 100 supports a mobile communication function. In particular, the wireless communication unit 150 according to the present invention can transmit the collected sensor information to the predetermined server 200. Also, the wireless communication unit 150 may receive an alarm message from the server 200 to inform the user of the health risk. The alarm message may include medical information, first aid treatment method, recommendation exercise, recommendation food, warning message, and the like. The wireless communication unit 150 transmits an emergency call request or emergency message to a preset contact (for example, emergency rescue unit, police station, hospital, doctor, friend, etc.) under the control of the main control unit 110 can do. At this time, the wireless communication unit 150 may transmit the location information of the user together. Also, the wireless communication unit 150 may receive the alarm condition (including at least one of the first alarm condition and the second alarm condition) from the server 200.

Meanwhile, the wireless communication unit 150 may form a communication channel with a peripheral device (an air conditioner, a heater, a boiler, a humidifier, etc.). For example, the portable terminal 100 may form a home network with a peripheral device through a wireless communication unit. The wireless communication unit 150 may transmit a control command to the peripheral device to control the surrounding environment so as not to affect the health of the user.

The display unit 130 displays various types of menus of the portable terminal 100 as well as information input by the user or information provided to the user. That is, the display unit 130 provides various screens such as a home screen, a menu screen, a message creation screen, a call screen, a schedule management screen, an address book screen, and a web page output screen according to the use of the portable terminal 100 can do. The display unit 130 may be turned off when the sleep mode is entered and turned on when the sleep mode is released. In particular, the display unit 130 according to an exemplary embodiment of the present invention may display a warning message indicating a user's health risk and an alarm message received from the server 200 under the control of the main control unit 110. The display unit 130 may be a liquid crystal display (LCD), an organic light emitting diode (OLED), or the like. Meanwhile, when the display unit 130 is formed as a touch screen, the display unit 130 may function as an input unit (not shown).

The audio processing unit 160 includes a speaker (SPK) for outputting audio data transmitted and received during a call, audio data included in a received message, audio data according to audio file playback stored in the main storage unit 120, And a microphone (MIC) for collecting voice or other audio signals. In particular, under the control of the main control unit 110, the audio processing unit 160 according to the present invention can output a warning sound through the speaker SPK to inform the user of the health risk.

The sensor unit 170 is controlled by the sub-control unit 140 and may collect information on the surroundings and the state of the mobile terminal 100. The sensor unit 170 may include an acceleration sensor, a motion sensor, a geomagnetism sensor, a temperature sensor, a humidity sensor, a pressure sensor, a pressure sensor, a gravity sensor, an ultraviolet sensor, a proximity sensor, . The sensor unit 170 may transmit the sensor value corresponding to the surrounding state and the state of the portable terminal 100 to the sub control unit 140 in the sleep mode and the active mode. That is, even if the portable terminal 100 enters the sleep mode, the sensor unit 170 can be driven by the low-power sub-control unit 140 to collect surrounding situation and status information.

2, the sensor unit 170 is connected to the sub-controller 140, but the present invention is not limited thereto. That is, the portable terminal 100 according to another embodiment of the present invention is configured such that the sensor unit 170 and the sub-control unit 140 are connected to each other in the sleep mode, and the sensor unit 170 and the main control unit 110, May be connected. In this case, the portable terminal 100 is connected to the sensor unit 170 and the sub-control unit 140 in the sleep mode, and switches the sensor unit 170 and the main control unit 110 to be connected in the active mode, (Not shown).

The sub-control unit 140 may control the driving of the sensor unit 170. The sub-controller 140 may be a low-power processor such as a micro processor unit (MPU) or an MCU (Micro Control Unit). For example, the sub-control unit 140 can collect temperature, humidity, ultraviolet rays, motion, air pressure, body temperature, blood pressure, electrocardiogram, radiation, and environmental substances through the sensor unit 170.

The sub-control unit 140 may include a sub-storage unit 141 for storing the collected sensor information. As the collected information is stored in the sub-storage unit 141, the sleep state of the main control unit 110 having a large current consumption can be maintained. On the other hand, when the storage space of the sub-storage unit 141 is insufficient, the sub-control unit 140 may transmit a wake-up signal to the main control unit 110. [ That is, when the storage space of the sub-storage unit 141 is insufficient, the sub-control unit 140 wakes up the main control unit 110 and moves the sensor information stored in the sub-storage unit 141 to the main storage unit 120 . Alternatively, when the storage space of the sub-storage unit 141 is insufficient, the sub-control unit 140 deletes the oldest sensor information stored in the sub-storage unit 141 to secure a storage space, The sensor information can be stored in the reserved storage space of the sub storage unit 141. [ At this time, when the main control unit 110 wakes up due to an external event (e.g., call reception, text message reception, physical key input, etc.), the sub- To the main storage unit 120 and store them.

In addition, the sub-controller 140 analyzes the collected sensor information and can confirm whether the first alarm condition stored in the sub-storage unit 141 is satisfied. The sub-control unit 140 may transmit an alarm request signal to the main control unit 110 when the analysis result of the collected sensor information satisfies the first alarm condition. At this time, when the main controller 110 is in the sleep state, the sub-controller 140 may transmit an alarm request signal after transmitting the wake-up signal to the main controller 110. [

2, the sub-storage unit 141 is included in the sub-control unit 140, but the present invention is not limited thereto. That is, the sub storage unit 141 may be included in a separate configuration. At this time, it is preferable that the separate sub storage unit 141 is driven with low power.

The main storage unit 120 stores an operating system (OS) of the portable terminal 100 and other application functions such as a sound playback function, an image or moving picture playback function, a broadcast playback function, User data, data transmitted and received in communication, and the like. For example, the main storage unit 120 may store a moving picture file, a game file, a music file, a movie file, and the like. In particular, the main storage unit 120 according to the present invention can store sensor information collected through the sensor unit 170. Alternatively, the main storage unit 120 may receive sensor information stored in the sub-storage unit 141 and store the sensor information. In addition, the main storage unit 120 may store a second alarm condition. Since the description of the second alarm condition has been described above, it will be omitted.

The main control unit 110 may control the overall operation of the portable terminal 100 and the signal flow between the internal blocks of the portable terminal 100 and may perform a data processing function of processing the data. For example, the main control unit 110 may be a central processing unit (CPU), an application processor, or the like, which consumes a large amount of current. In particular, the main controller 110 according to the present invention enters a sleep mode when there is no event to reduce current consumption. The main controller 110 may be activated when receiving a wake-up signal from the sub-controller 140 in the sleep mode. For example, when the sensor information collected through the sensor unit 170 can not be stored because the storage space of the sub-storage unit 141 is insufficient, the main control unit 110 may wake up the sub-control unit 140 . The wake-up main controller 110 may move the sensor information stored in the sub-storage unit 141 to the main storage unit 120. [ Alternatively, the main control unit 110 may control the sub-control unit 140 to move the sensor information stored in the sub-storage unit 141 to the main storage unit 120 when the external event wakes up.

Also, the main control unit 110 may be woken up upon reception of an alarm request signal from the sub-control unit 140. The alarm request signal is generated by the sub-controller 140 when the analysis result of the collected sensor information satisfies the first alarm condition. Also, the main control unit 110 may be woken up when receiving an alarm message informing the user of the health risk from the server 200 through the wireless communication unit 150. [

Meanwhile, the main control unit 110 may periodically analyze the sensor information stored in the main storage unit 120. At this time, the main control unit 110 may analyze sensor information received for a predetermined period according to an alarm condition. For example, when analyzing the ultraviolet ray exposure, the controller 110 analyzes the sensor information (information collected by the ultraviolet sensor) collected for 1 hour to 2 hours, analyzes the weekly momentum, Sensor information (sensor information collected through geomagnetism sensor, acceleration sensor, gravity sensor, etc.) can be analyzed. If the analysis result of the sensor information satisfies the second alarm condition, the main control unit 110 can notify the alarm.

The main control unit 110 receives an alarm request signal or an alarm message, or can notify an alarm when the second alarm condition is satisfied. The main control unit 110 displays a warning message informing the user of the danger of health on the display unit 130 and outputs a warning sound through the speaker SPK of the audio processing unit 160 or a vibration motor The alarm can be notified. Alternatively, the main control unit 110 may transmit an emergency call or an emergency message to a preset contact (e.g., emergency rescue team, police station, designated hospital, doctor, friend, etc.). At this time, the main control unit 110 may check the current location information through a GPS receiving unit (not shown), a triangular position measurement method through the base station, and transmit the current location information together. Such a position measuring method will not be described in detail with a known technique.

In addition, the main control unit 110 may disable the alarm by controlling a peripheral device (for example, an air conditioner, a heater, a humidifier, a boiler, etc.) That is, the main control unit 110 may control the peripheral device to maintain an environment suitable for health. For example, when the room temperature is maintained at 26 degrees Celsius or less for 1 hour or more during the summer, the main control unit 110 increases the room temperature by controlling the air conditioner. If the room temperature is maintained at 30 degrees Celsius or more for 1 hour or more, It is possible to reduce the room temperature. Alternatively, when the room temperature is maintained at 18 degrees Celsius or less for 1 hour or more during the winter, the main control unit 110 controls the heater or the boiler to increase the room temperature, and the room temperature is maintained at 23 degrees Celsius or more for 1 hour or more In case the heater or boiler is controlled, the room temperature can be increased. Similarly, the main control unit 110 may control the humidifier to properly maintain the humidity.

2, the portable terminal 100 includes a Global Positioning System (GPS) module for receiving location information, a broadcast receiving module for receiving broadcasts, a digital sound source playback module such as an MP3 module, and an Internet function And an Internet communication module for performing the functions of the present invention. Although these components can not be enumerated due to various convergence trends of the digital devices, the portable terminal 100 according to the present invention may include components having the same level as the above- .

3A is a flowchart illustrating a method of collecting sensor information of a wireless terminal according to an exemplary embodiment of the present invention.

1 to 3A, the sub-control unit 140 of the portable terminal 100 according to an embodiment of the present invention can collect sensor information in step 301. FIG. The sensor information is collected through the sensor unit 170 connected to the sub-controller 140. The sensor unit 170 may include a plurality of sensors for recognizing the environment information and the user status information as described above. The plurality of sensors can operate periodically in consideration of current consumption. At this time, the operation cycle of each sensor may be set differently. For example, the ultraviolet sensor may have a duty cycle of a few seconds to a few minutes, and the temperature sensor and the humidity sensor may have a duty cycle of several minutes to several tens of minutes.

In step 303, the sub-controller 140 may determine whether the main controller 110 is in a sleep mode. If the main control unit 110 is not in the sleep mode, the sub-control unit 140 proceeds to step 313 described later. If the main control unit 110 is in the sleep mode, the sub-control unit 140 proceeds to step 305 to check the storage space of the sub-storage unit 141. In step 307, It is possible to confirm whether or not it can be stored in the storage unit 141. If the collected sensor information can be stored in the sub-storage unit 141, the sub-controller 140 proceeds to step 309 to store the collected sensor information in the sub-storage unit 141, have. On the other hand, if the collected sensor information can not be stored in the sub-storage unit 141, the sub-control unit 140 may proceed to step 311 to wake up the main control unit 110. [

Next, the wake-up main controller 110 may store the collected sensor information in the main storage unit 120 in step 313. At this time, the sub-control unit 140 may move the sensor information stored in the sub-storage unit 141 to the main storage unit 120.

When the movement of the sensor information is completed, the sub-control unit 140 may repeat the above-described process in step 301. [ At this time, the main control unit 110 enters a sleep state.

In FIG. 3A, the sub-controller 1440 collects sensor information regardless of whether the apparatus is in the sleep mode or not. However, the embodiment of the present invention is not limited to this. For example, when the sensor unit 170 is switchable between the main control unit 110 and the sub control unit 140 through a switch (not shown), the main control unit 110 collects sensor information in the active mode, The sub-controller 140 may collect sensor information in the sleep mode.

As described above, according to the embodiment of the present invention, since the main control unit 110 having a large current consumption is kept in a sleep state and the sensor information is collected through the sub control unit 140 having low current consumption, Can be minimized. Thus, an embodiment of the present invention can continuously collect sensor information over a long period of time. On the other hand, the conventional portable terminal can not continuously collect sensor information because current consumption is large.

FIG. 3B is a flowchart illustrating a method of collecting sensor information of a wireless terminal according to another exemplary embodiment of the present invention. Referring to FIG.

1 to 3B, the portable terminal 100 according to another embodiment of the present invention may enter the sleep mode in step 331. In this case, The sleep mode may have no input for a predetermined period of time (for example, 30 seconds) or may be entered at the request of the user.

When the portable terminal 100 enters the sleep mode, the sub-control unit 140 may collect sensor information in step 333. FIG. The sensor information is collected through the sensor unit 170 connected to the sub-controller 140. The sensor unit 170 may include a plurality of sensors for recognizing the environment information and the user status information as described above. The plurality of sensors can operate periodically in consideration of current consumption. At this time, the operation cycle of each sensor may be set differently. For example, the ultraviolet sensor may have a duty cycle of a few seconds to a few minutes, and the temperature sensor and the humidity sensor may have a duty cycle of several minutes to several tens of minutes.

The sub control unit 140 checks the storage space of the sub storage unit 141 in step 335 and confirms whether the sensor information collected in step 337 can be stored in the sub storage unit 141. [ If the sensor information collected in step 337 can be stored in the sub-storage unit 141, the sub-control unit 140 proceeds to step 339 to store the collected sensor information in the sub-storage unit 141, Step 345 may be performed.

On the other hand, if the sensor information collected in step 337 is not stored in the sub storage unit 141, for example, if the storage space of the sub storage unit 141 is insufficient, the sub control unit 140 proceeds to step 341 At least some of the sensor information stored in the sub-storage unit 141 may be deleted to secure a storage space. For example, the sub-controller 140 may delete the oldest sensor information and re-check the storage space. That is, the sub-controller 140 may delete old sensor information in the storage order until the storage space for storing the collected sensor information is secured.

Alternatively, the sub-control unit 140 may delete the sensor information stored in the sub-storage unit 141 based on a predetermined size (for example, 5 MB). For example, the sub-controller 140 may delete a plurality of sensor information whose storage order is out of order so that a storage space of 5 MB or more is secured.

Alternatively, the sub-control unit 140 may delete the sensor information stored in the sub-storage unit 141 based on a predetermined time. For example, the sub-control unit 140 may delete sensor information having a time difference of two minutes based on the oldest sensor information.

Alternatively, the sub-controller 140 may check the size of the collected sensor information, and delete the old sensor information so that a storage space corresponding to the size of the detected sensor information is secured.

The sub-controller 140 may store the sensor information collected in the secured storage space in step 343. FIG. The sub control unit 140 can confirm whether the main control unit 110 is woken up in step 345. [ The main control unit 110 may be woken up by an external event such as call reception, text message reception, alarm, physical key input, or the like.

If the main control unit 110 is not woken up in step 345, the sub-control unit 140 may return to step 333 and repeat the above-described process. On the other hand, when the main control unit 110 wakes up in step 345, the sub-control unit 140 proceeds to step 347 to move the sensor information stored in the sub-storage unit 141 to the main storage unit 120 and store .

In another embodiment of the present invention, the time during which the main control unit 110 is unnecessarily woken up can be reduced. For example, the main control unit 110 can wait until the main control unit 110 is woken up by the external event without waking up the main control unit 110 even if the sub-storage unit 141 has insufficient storage space. In this way, the unnecessary main control unit 110 can be prevented from waking up, and the current consumption can be further reduced according to another embodiment of the present invention. Another embodiment of the present invention will be useful when sensor information over a certain period of time is meaningless. For example, when it is assumed that the compensation value is calculated using only the sensor information for a predetermined time (for example, 15 minutes), the sensor information is not moved to the main storage unit 120 and stored , It may be useful to delete and store outdated sensor information as in other embodiments of the present invention.

4 is a flowchart illustrating an alarm notification method of a portable terminal according to an embodiment of the present invention. Hereinafter, a case where the portable terminal is in the sleep state will be described as an example.

Referring to FIGS. 1 to 4, the sub-controller 140 according to an embodiment of the present invention may periodically collect sensor information in step 401. FIG. Here, detailed description of the sensor information collection has been described above with reference to FIGS. 3A and 3B, and therefore will not be described here.

The sub-controller 140 analyzes the sensor information in step 403 and confirms whether the predetermined first alarm condition is satisfied in step 405. If the analysis result of the sensor information does not satisfy the first alarm condition, the sub-controller 140 returns to step 401 and repeats the above-described process. On the other hand, if the analysis result of the sensor information satisfies the first alarm condition, the sub-control unit 140 may proceed to step 407 to wake-up the main control unit 110. [

The wake-up main controller 110 may notify the alarm in step 409. [ The alarm notification may be a warning message and / or a warning tone signaling a dangerous situation such as ultraviolet ray exposure, hypothermia, air-condition or the like. Alternatively, the alarm notification may be an emergency call to an established contact (emergency rescue team, hospital, doctor, friend, etc.) or an emergency message transmission request.

Meanwhile, the main control unit 110 may control a peripheral device (e.g., an air conditioner, a heater, a humidifier, a boiler, etc.) that is wirelessly connected (e.g. For example, when the indoor temperature is maintained at 26 degrees Celsius or lower for 1 hour or more during the summer, the portable terminal 100 increases the room temperature by controlling the air conditioner. If the indoor temperature is maintained at 30 degrees Celsius or more for 1 hour or more, Can be controlled. Alternatively, if the room temperature is maintained at 18 degrees Celsius or lower for 1 hour or more during the winter, the portable terminal 100 increases the room temperature. If the room temperature is maintained at 23 degrees Celsius or more for 1 hour or more, The boiler can be controlled. Similarly, the portable terminal 100 can control the humidifier to properly maintain the humidity.

In the above description, the sub-control unit 140 analyzes the collected sensor information in the sleep state and notifies the alarm by comparing with the first alarm condition. However, the present invention is not limited thereto. That is, the sub-controller 140 has limited performance due to its low power design. Also, the amount of sensor information stored in the sub-storage unit 141 may be limited. Therefore, the present invention analyzes the sensor information stored in the main storage unit 120 at regular intervals when the complex operation is required, such as when analyzing sensor information for a long time (for example, a day or a week) The analysis result is compared with the second alarm condition, and an alarm can be notified when the analysis result satisfies the second alarm condition. At this time, if the main control unit 110 is in a sleep state at the time when analysis of sensor information requiring a complicated operation is required, the main control unit 110 can be woken up. On the other hand, when the sensor information is analyzed for a very long time (for example, one month, one year) or when a very complicated operation is required, the analysis and alarm of the sensor information can be performed by the server 200. That is, the server 200 analyzes the stored sensor information received from the portable terminal 100 at regular intervals, compares the analysis result with a third alarm condition, and when the analysis result satisfies the third alarm condition An alarm message can be generated and transmitted to the mobile terminal 100.

In FIG. 4, the alarm information is notified using the collected sensor information. However, according to another embodiment of the present invention, the measured sensor information may be used to correct the measured value of the sensor. For example, when the portable terminal 100 is used for a long period of time in the case of providing an external temperature and / or humidity measurement function, heat is generated. Therefore, the portable terminal 100 can not measure the accurate external temperature and / or humidity. Therefore, another embodiment of the present invention is to calculate the compensation value through the collected sensor information (temperature and / or humidity), appropriately compensate the measured value through the temperature and humidity sensor with the calculated compensation value, Results can be provided.

5 is a flowchart illustrating sensor information collection and alarm notification methods in a sensor information management system according to an embodiment of the present invention.

Referring to FIGS. 1 to 5, the portable terminal 100 may collect sensor information in step 501. FIG. Here, the detailed description of the sensor information collection has been described above with reference to FIGS. 3A and 3B, and therefore will not be described here.

The mobile terminal 100 may transmit the sensor information collected in step 503 to the server 200. [ The transmission of such sensor information may be performed periodically. At this time, the server 200 may be a server operated in a hospital designated by a user, a server of a health care center operated by a government agency, a personal server, or the like. The reason why the collected sensor information is transmitted to the server 200 is that there is a limit to the performance (information processing capability, storage space) of the mobile terminal 100. [ For example, the portable terminal 100 may lack storage space for storing sensor information collected over a year. Also, it may be difficult to analyze the sensor information collected over one year due to the performance restriction of the main control unit 110 of the portable terminal 100. [

Next, the portable terminal 100 analyzes the sensor information in step 505, and in step 507, it can check whether the analysis result of the sensor information satisfies a predetermined alarm condition (the first alarm condition or the second alarm condition) . If the alarm condition (including the first alarm condition or the second alarm condition) is not satisfied, the portable terminal 100 returns to step 501 and repeats the above-described process. The analysis of the sensor information may be performed by the sub-control unit 140 using the first alarm condition or by the main control unit 110 using the second alarm condition as described above. On the other hand, if the alarm condition (the first alarm condition or the second alarm condition) is satisfied, the portable terminal 100 can notify the alarm in step 509. [ Since the detailed description of the alarm notification has been described above, it will be omitted.

Meanwhile, the server 200 analyzes the sensor information transmitted from the portable terminal 100 in step 511 and confirms whether the third alarm condition is satisfied in step 513. If the third alarm condition is not satisfied, the server 200 returns to step 511 and repeats the above-described process. The server 200 may perform sensor information analysis at predetermined intervals. On the other hand, if the third alarm condition is satisfied, the server 200 proceeds to step 515 and generates an alarm message. In step 517, the server 200 may transmit the alarm message to the portable terminal 100. The alarm message may include medical information, first aid method, recommendation food, recommendation exercise, location of a nearby hospital or pharmacy, etc. to help a user's health condition.

The present invention described above can be utilized variously. For example, the present invention can alarm an ultraviolet ray exposure using an ultra violet ray (UV) sensor mounted on the portable terminal 100 during mountain climbing. In detail, the sub-control unit 140 periodically drives the ultraviolet sensor to store the sensed value in the sub-storage unit 141. When the ultraviolet light value continuously exceeds the danger value, the sub-control unit 140 controls the main control unit 110 Wake-up. The wake-up main control 110 may output a warning message and / or a warning sound recommending the user to refrain from outdoor activities or to cover the skin because the ultraviolet ray exposure index is dangerous to the user. At this time, the user preferably exposes the portable terminal 100 to the outside so that ultraviolet ray measurement can be performed. The sensing period of the ultraviolet sensor may be set to several seconds to several minutes by the user.

Further, the present invention can be utilized for alarming the attention of the user during the period of the seasonal change. In detail, the portable terminal 100 may analyze the sensor information collected through the temperature sensor and the humidity sensor to check whether the environment is susceptible to a cold, and inform the user of the result. That is, if the difference between the maximum temperature and the minimum temperature is large during a day and the low temperature is maintained, the portable terminal 100 may output a warning message to the user because it is exposed to the environment where the user is likely to be caught by the user. Since the portable terminal 100 is almost always located around the user, the user can collect information about the environment of the user more accurately and objectively and provide the health information accordingly.

Further, the present invention can be utilized in a hypothermia notification system. In detail, the portable terminal 100 may collect and store the ambient temperature periodically (e.g., several minutes) through a temperature sensor. The portable terminal 100 analyzes the sensor information at regular intervals and outputs a warning sound indicating that hypothermia is caused when the temperature of 0 degrees Celsius or less lasts for 1 hour or more, or blinks light (display unit or camera flash) An alarm can be notified. Alternatively, the portable terminal 100 can transmit an emergency call or an emergency message to a predetermined contact (emergency rescue unit, emergency center or friend). At this time, the portable terminal 100 can measure the current position and transmit the position information together.

Further, the present invention can be utilized in a cooling system for preventing air-cooling. Specifically, the portable terminal 100 periodically measures and stores temperature through a temperature sensor. At this time, the portable terminal 100 measures and stores the temperature in units of minutes or tens of minutes through the sub-control unit 140 and the temperature sensor even in the sleep state, and the main control unit 110 measures the temperature in units of 1 hour or 2 hours So that the temperature information collected through the sub-control unit 140 can be analyzed. As a result of the analysis, when the temperature is maintained at 20 degrees or less for 3 hours or more, the main control unit 110 alerts the user to the air conditioner warning and can alarm the air conditioner alarm when the temperature is maintained for 5 hours or more. At this time, if the portable terminal 100 is interlocked with the air conditioner through a wireless connection (home network system), the portable terminal 100 can automatically prevent the air conditioner by controlling the temperature of the air conditioner.

Further, the present invention can be utilized in a patient management system. In detail, the server of the hospital can periodically receive and store the sensing information from the portable terminal 100 of the patient who needs continuous health care. At this time, the primary care physician can check the health state of the patient through the stored sensing information. In other words, the primary care physician can continuously monitor the patient's condition. For example, if a patient is exposed to a dry environment, the PCP can invite the patient to take appropriate action by calling or sending a message. Alternatively, the degree of motion of the patient measured by the motion sensor among the sensing information transmitted from the patient requiring regular exercise may be checked. If the motion of the patient is insufficient (for example, ) The doctor can invite a walking exercise through phone call or message transmission.

Further, the present invention can be utilized for environmental information measurement. In detail, the portable terminal 100 collects and stores sensor information, and transmits the collected sensor information periodically to a government agency such as a health care center. The health care center can receive the sensing information collected from the portable terminals of the citizens and analyze the health state of the area. For example, the healthcare center can quantitatively collect trends of the general movement of the people, and can estimate the behavior pattern of the people through long-accumulated information analysis, and can design a policy suitable for them. Alternatively, the health care center can separately analyze the collected sensing information and notify health risk information through a phone call or a message to a user who is frequently exposed to an unhealthy environment.

Further, the present invention can be utilized for personal life pattern management. In detail, the portable terminal 100 may collect and analyze sensing information for a long period of time (for example, one year) to provide health information according to a user's life pattern. For example, when the user lives on an average dry environment, the portable terminal 100 or the server 200 can notify the user that the environment is inappropriate for respiratory diseases, and can provide appropriate measures. Alternatively, the portable terminal 100 or the server 200 may recommend medical information indicating that vitamin D may be insufficient due to a shortage of the go out when there is no ultraviolet ray detection for a long period of time, and foods rich in vitamin D or the like. The sensor information collected over a long period of time may be stored in the main storage unit of the portable terminal or may be transmitted to the designated server periodically and managed.

The method of managing sensor information of a portable terminal according to an embodiment of the present invention as described above may be implemented in the form of a program command that can be executed through various computer means and recorded in a computer readable recording medium. At this time, the computer readable recording medium may include a program command, a data file, a data structure, or the like, alone or in combination. On the other hand, the program instructions recorded on the recording medium may be those specially designed and configured for the present invention or may be available to those skilled in the art of computer software. The computer-readable recording medium includes magnetic media such as a hard disk, a floppy disk and a magnetic tape, an optical medium such as a CD-ROM and a DVD, and a magnetic recording medium such as a floppy disk. Optical media, and hardware devices specifically configured to store and execute program instructions such as ROM, RAM, flash memory, and the like.
