Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an automatic monitoring system for crime prevention and emergency notification.
[0002]
[Prior art]
Conventionally, this type of monitoring system has been a combination of a plurality of sensor terminals for detecting intruders installed at monitoring locations such as windows and doors, and a central processing unit that issues an alarm. When the monitoring operation is started, the central processing unit checks the output signal from the terminal device and starts the monitoring operation. Specifically, for example, when a steady state in which all windows and doors are closed is detected by each terminal, the monitoring operation is started as it is. On the other hand, if an unsteady state such as an open window or door was detected by the terminal, a message was issued from the central processing unit to confirm the monitoring location of the terminal. . The user specifies the relevant window or door based on the message, closes the relevant window or door, sets the start of the monitoring operation again by the central processing unit, and starts the monitoring operation.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, when any of the windows or doors is open, the task of specifying the corresponding window or door based on a message from the central processing unit is relatively difficult for a person who has installed a terminal device. Although it can be easily performed, there is a problem that it takes time and effort when a family other than the set-up person finds the corresponding monitoring place. In particular, when a house is large and many terminals are installed, there is a problem that it takes time to find a corresponding monitoring place.
[0004]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a monitoring system capable of easily specifying a monitoring place where an unsteady state is detected when starting a monitoring operation.
[0005]
[Means for Solving the Problems]
In order to solve the conventional problem, a monitoring system of the present invention monitors a plurality of terminals in a steady or unsteady state and notifies the plurality of terminals and communicates with the terminals to control a monitoring operation of the terminals. A central processing unit, wherein the central processing unit checks the state of the terminal device when starting a monitoring operation, and if there is a terminal device that has detected an unsteady state, the terminal device is in an unsteady state with respect to the terminal device A notification request signal is transmitted so as to notify the user.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
According to the first aspect of the present invention, when the central processing unit starts the monitoring operation, the state of the terminal is confirmed, and if there is a terminal that has detected the unsteady state, the terminal is in the unsteady state. By transmitting the notification request signal to perform the notification, the terminal device notifies the terminal device that it is in an unsteady state. Therefore, it is possible to easily specify the monitoring place where the unsteady state is detected.
[0007]
According to the second aspect of the present invention, when the terminal receives a monitoring start signal for starting a monitoring operation from the central processing unit, the terminal checks the state of the monitoring place. Notifying that it is in a steady state, and transmitting a detection signal in an unsteady state to the central processing unit, and controlling the monitoring operation based on the detection signal, the central processing unit sends an unsteady state from the terminal unit. Since the state is notified, the monitoring place where the unsteady state is detected can be easily specified.
[0008]
According to the third aspect of the present invention, when the terminal detects an unsteady state during the monitoring operation, and when the terminal detects the unsteady state at the start of the monitoring operation, the terminal performs different notification. When windows and doors are open, the volume of the alarm can be set lower than when an unsteady state occurs due to intrusion, etc., and an alarm can be generated. Don't bother.
[0009]
According to the fourth aspect of the present invention, since the terminal device and the central processing unit each have voice communication means for transmitting or receiving a voice signal, a voice call can be made between the terminal device and the central processing unit. If an unsteady state is detected at the start, the monitoring location of the terminal can be confirmed by voice communication between the terminal and the central processing unit.
[0010]
According to a fifth aspect of the present invention, when there is a terminal that has detected an unsteady state, the central processing unit stores the installation location information of the terminal in at least one terminal based on the installation location information of the terminal registered in advance. Transmitted to the terminal, the terminal device that has received the installation location information notifies the installation location information of the terminal device, so that the terminal device can know the installation location information of the terminal device. The detected monitoring location can be more easily specified.
[0011]
A sixth aspect of the present invention is a program for causing a computer to execute at least one unit of the monitoring system according to any one of the first to fifth aspects.

[0019]
The operation of the present invention will be described based on the above configuration and FIG. FIG. 6 is a flowchart showing the operation of the first embodiment.
[0020]
First, when the user goes out, when the alert mode is set by the setting unit 16 of the central processing unit 1 in step ST1, the data communication unit 12 confirms the state of the terminal to the terminals 2 to 4 in step ST2. A confirmation request signal is transmitted. In the terminals 2 to 4, when the data communication means 21 and 28 receive the confirmation request signal, the states of the intrusion detection means 19 and the human body detection means 26 are confirmed by the terminal control means 20 and 27, respectively. When it is confirmed that the terminals 2 to 4 are in a steady state such that the windows and doors are closed and there are no obstacles in the passage, a state confirmation signal is sent to the central processing unit by the terminal control means 20 and 27. 1 is transmitted to the first data communication unit 12. When the data communication unit 12 receives the state confirmation signal and the control unit 18 confirms that the terminals 2 to 4 are in the steady state, the alert operation starts in step ST3.
[0021]
Next, a case will be described in which at least one of the terminals 2 to 4 is in an unsteady state, such as a window or a door of a monitoring place being opened or a curtain entering the passage by wind. In step ST2, a confirmation request signal for confirming the state of the terminal is transmitted from the data communication means 12 to the terminals 2 to 4, and when the data communication means 21 and 28 of the terminals 2 to 4 receive the confirmation request signal, The states of the intrusion detecting means 19 and the human body detecting means 26 are confirmed by the terminal control means 20 and 27. Here, for example, assuming that the window monitored by the terminal 2 is open, a state confirmation signal is transmitted to the data communication unit 12 of the central processing unit 1, and the terminal 2 is in an unsteady state by the control unit 18. Is confirmed, and the start of the alert operation is suspended. Then, a notification request signal is transmitted from the data communication means 12 to the terminal device 2 by the control means 18 in step ST4 to notify the terminal device 2 of the non-stationary state. When the data communication unit 21 of the terminal device 2 receives the notification request signal, an alarm is generated from the notification unit 25 by the terminal control unit 20, and the LED blinks. The user hears the warning or sees the blinking of the LED, identifies the window where the unsteady state is detected, and closes the window. Thereby, all the monitoring locations are in a steady state, so that the alerting operation can be started based on the procedure described above. The volume of the alarm is set to be lower than the volume of an alarm generated when an unsteady state is detected during the alert operation.
[0022]
If it is difficult to determine the monitoring place even by an alarm or blinking of the LED, the voice communication means 22 and 29 of the terminals 2 to 4 and the voice communication means 13 of the central processing unit 1 cause the terminals 2 to 4 and the central processing unit 1 to operate. A voice call can be made between the central processing unit 1 and the person at the central processing unit 1 makes a voice call with the person at the terminal side based on the installation location information of the terminal registered in the central processing unit 1 in advance. The monitoring location can be confirmed by teaching the installation location of the terminal.
[0023]
Further, based on the pre-registered terminal installation location information, the terminal installation location is transmitted as audio data from the central processing unit 1 to the audio communication means 22, 29, 36 of the terminals 2 to 5, and the terminal From 2 to 5, the installation location information of the terminal can also be notified by voice, and the monitoring location can be confirmed based on the voice notification content. Next, the terminal 2 or 3 is installed during the alert operation. When the opened window or door is opened, the intrusion detecting means 19 operates, and a signal indicating occurrence of an unsteady state is output to the data communication means 21 in the terminal 2 or 3. When receiving this signal, the data communication unit 21 transmits a signal to the data communication unit 12 of the central processing unit 1. This signal first transmits an address code of its own terminal and a status code indicating that an intrusion has occurred. In the central processing unit 1, the data communication means 12 receives the transmission signal, determines which terminal the signal is from, and further receives a signal indicating that intrusion has occurred. Based on this signal, the transmission / reception unit 17 operates, and the name of the location where the intrusion has occurred in the fixed telephones 9 and 11 or the mobile phone 10 outside the home corresponding to the telephone number registered in advance via the public line 8 and the intrusion occurrence A voice message notifying the effect is sent.
[0024]
Next, the user who is notified by the telephone outside the home transmits a predetermined tone signal from the telephone, and operates the voice communication unit 13 by the transmission / reception unit 17. The central processing unit 1 sends a common calling signal to a plurality of terminals by the control means 18. For example, assuming that the terminal device that has transmitted the unsteady signal is the terminal device 2, in the terminal device 2, the voice communication means 22 is in a standby state in advance by the terminal control unit 20, and the voice signal from the voice communication means 13 of the central processing unit 1 Upon receiving the common call signal, the voice communication means 22 of the terminal operates to establish a communication configuration with the external telephone. As a result, the voice around the terminal can be monitored by the telephone outside the house through the voice input means 24, and the surrounding situation can be intercepted. Also, if necessary, the intruder can be threatened by the voice of the user from the voice output means 23 through the telephone. In the present embodiment, the terminal device 2 is provided with both the sound output means 23 and the sound input means 24. However, only one of them may be provided as necessary.
[0025]
In addition, even when the user is at home, when the user goes to bed at night, the setting unit 16 of the central processing unit 1 sets the alert mode corresponding to the at-home state. In this case, if an intrusion occurs, the voice signal from the terminal is not transmitted to the outside line phone but is louder from the voice output means 14 of the central processing unit 1. This allows the central processing unit 1 to intercept the situation by the voice around the terminal. In this case, a voice signal is output from the voice input means 15 of the central processing unit 1 to the corresponding terminal. This allows the central processing unit 1 to perform a voice threat against the intruder on the terminal. In the present embodiment, the central processing unit 1 is provided with both the audio output means 14 and the audio input means 15, but any one may be provided as needed.
[0026]
Note that the human sensor 4 performs the same operation as the terminal device 2.
[0027]
Next, an operation related to an emergency call will be described. The user activates the emergency call means 33 of the terminal 5 when an intrusion occurs even when at home and urgency is required, or when the physical condition of the user suddenly changes and it is necessary to contact the outside. Similarly, the terminal address code and the emergency status code are transmitted to the central processing unit 1, and based on this, the corresponding voice message can be reported to the external telephone or mobile phone by the transmission / reception unit 17. it can. The contacted person who has received the notification on the telephone outside the home can then transmit a predetermined tone signal from the telephone, and operate the voice communication unit 13 by the transmission / reception unit 17. In the terminal 5 that has transmitted the unsteady signal, the voice communication means 36 is in a standby state by the terminal control unit 34, and when receiving a calling signal from the voice communication means 13 of the central processing unit 1, the voice communication means of the terminal 5 is received. 36 operates. As a result, the voice of the user carrying the terminal device 5 can be monitored on the telephone outside the home through the voice input means 38, and the status of the user can be confirmed. Also, if necessary, it is possible to call the user by the voice of the contactee from the voice output means 37 through the telephone. In the present embodiment, the terminal device 5 is provided with both the sound output means 37 and the sound input means 38, but may be provided with any one as needed.
[0028]
In the case where the communication is made not to the outside but to the cohabitant, the voice signal from the terminal is not transmitted to the outside line depending on the setting, but the voice output means 14 of the central processing unit 1 is used. Will be voiced from. This allows the central processing unit 1 to confirm the situation by voice of the user carrying the terminal. In this case, a voice signal is output from the voice input means 15 of the central processing unit 1 to the corresponding terminal. This allows the central processing unit 1 to make a voice call to the user carrying the terminal. In the present embodiment, the central processing unit 1 is provided with both the audio output means 14 and the audio input means 15, but any one may be provided as needed.
[0029]
By the above operation, when the central processing unit starts the monitoring operation, the state of the terminal is confirmed, and if there is a terminal detecting the unsteady state, the terminal is notified of the unsteady state. By transmitting the notification request signal as described above, the terminal is notified of the non-stationary state, so that the monitoring place where the non-stationary state is detected can be easily specified.
[0030]
This embodiment is a system for crime prevention and emergency notification, and the unsteady state here indicates a state where an intrusion has occurred or a state where an emergency has occurred. The same configuration applies to the other systems. That is, in the case of disaster prevention, the unsteady state includes a state of occurrence of a fire, an earthquake, a gas leak, a toxic gas, and the like, and it is sufficient to provide a detection unit corresponding to each state in the terminal. In the case of a medical system, the unsteady state may be a sudden change in a physiological index such as blood pressure, pulse, respiration, or blood component, and a corresponding detection means may be provided in the terminal. Even in these cases, it is very effective means to confirm the situation of the site where the unsteady state has occurred by external communication means or to make a call.
[0031]
In this embodiment, the number of terminals is five and the number of terminals having emergency call means is one. However, the number is not particularly limited, and the address code and the status code of the terminal are specified. As far as possible, any number of terminals may be used.
[0032]
Further, although the emergency call means of the present embodiment is constituted by a push button switch, a type using other mechanical contact mechanism such as a type in which the contact is closed by grasping may be used, or a sphygmomanometer or a pulse meter may be used. A similar effect can be obtained even if the sudden change in state is transmitted as occurrence of an unsteady state automatically in conjunction with a sensor for measuring a physiological index.
[0033]
Further, in this embodiment, wireless communication is used as a communication medium, but the same effect can be obtained by using a communication medium such as wired communication using a dedicated line, power line communication, infrared communication, or optical fiber communication. is there.
[0034]
