Embodiments of the present invention provide a method, device, and terminal for detecting air quality, which will be described in detail below.

Embodiment one

This embodiment will be described from the perspective of a device for detecting air quality. Specifically, the device may be integrated into a terminal, and the terminal may be a smart phone, a tablet computer, or other devices.

A method for detecting air quality, comprising: acquiring environmental information of the environment where the terminal is located; judging whether the terminal is in an open environment according to the environmental information; if the judgment result is yes, acquiring the air quality information of the environment where the terminal is located; According to the air quality information, corresponding prompt information is displayed on the terminal.

As shown in Figure 1, the method for detecting air quality, the specific process may include:

S101. Obtain environment information of the environment where the terminal is located.

Specifically, during the process of using the terminal by the user, the terminal may be in many different environments. For example, the terminal may be placed in the user's hand, on a table, in the user's pocket, or in a backpack. When using a terminal to detect air quality, only when the terminal is in an open environment (environmental state where air can circulate freely) such as the user's hand or on a table, the detected air quality information has reference significance. Because only in an open environment, the air can convect, and the detected air quality parameters can reflect the real air quality conditions. The environment information may be the ambient brightness of the environment where the terminal is located, or the distance between the terminal and an external object. Acquiring the environment information of the environment where the terminal is located may specifically include the following steps:

Get the ambient light intensity of the environment where the terminal is located.

In a specific application, when the terminal is in an open environment, usually the ambient light intensity of the environment is relatively high. For example, when the terminal is indoors or outdoors, it may receive sunlight or indoor light, and the ambient light intensity of the environment is relatively high. The ambient light intensity of the environment where the terminal is located may be acquired through a light sensor.

Acquiring the environment information of the environment where the terminal is located may specifically include the following steps:

Get the distance between the terminal and the object closest to the terminal.

In a specific application, a distance sensor (for example, an infrared sensor) is provided on the front of the terminal. The distance between the terminal and the object closest to the terminal is detected by the distance sensor. When the terminal is in an open environment, it is usually far away from objects in front of the terminal. For example, when the terminal is in the user's hand or on a table, it is detected that the distance between objects closest to the terminal is relatively far.

S102. Determine whether the terminal is in an open environment according to the environment information.

Specifically, after acquiring the environment information of the environment where the terminal is located, it is determined whether the terminal is in an open environment by judging whether the environment information satisfies a preset condition. An open environment refers to an environment in which air can circulate freely. Judging whether the terminal is in an open environment according to the environment information may specifically include the following steps:

It is judged whether the ambient light intensity is greater than a preset ambient light intensity.

In a specific application, when the environmental information acquired in S101 is ambient light intensity, it is judged whether the ambient light intensity is greater than a preset ambient light intensity. The preset ambient light intensity is an ambient light intensity value pre-stored in the terminal. For example, the preset ambient light intensity may be 100cd (candela). After the ambient light intensity is acquired, the preset ambient light intensity stored in the terminal is called, and the acquired ambient light intensity is compared with the preset ambient light intensity to determine whether the ambient light intensity is greater than the preset ambient light intensity.

Judging whether the terminal is in an open environment according to the environmental information may also specifically include the following steps:

It is judged whether the distance is greater than a preset distance.

In a specific application, when the environment information acquired in S101 is the distance between the terminal and an external object closest to the terminal, it is determined whether the distance is greater than a preset distance. The preset distance is a distance value pre-stored in the terminal. For example, the preset distance may be 0.2m. After the distance between the terminal and the external object is acquired, the preset distance stored in the terminal is invoked, and the acquired distance is compared with the preset distance to determine whether the distance is greater than the preset distance.

S103, if the determination result is yes, acquire the air quality information of the environment where the terminal is located.

In a specific application, the terminal is provided with an air quality sensor. When the determination result in S102 is that the terminal is in an open environment, the air quality information of the environment where the terminal is located is acquired through the air quality sensor. The air quality information may be the content of fine particulate matter (PM2.5) in the air.

Specifically, the air quality sensor may include an infrared transmitter and an infrared receiver. The infrared rays emitted by the infrared transmitter irradiate air dust (air containing fine particles), and then reach the infrared receiver. After the infrared receiver receives the infrared rays, it generates corresponding electrical signals. When the content of fine particles in the air is different, the intensity of infrared rays received by the infrared receiver is also different, and the electrical signals generated are also different. The terminal calculates the corresponding fine particle concentration, that is, the PM2.5 value, according to the electrical signal.

There may be certain errors in the data detected by the air quality sensor. Therefore, after obtaining the air quality information of the environment where the terminal is located, the following steps may also be included:

Obtain the compensation value of the air quality information;

The air quality information is corrected according to the compensation value to obtain corrected air quality information.

Specifically, the compensation value may be a specific numerical value or a percentage. There are several ways to obtain the compensation value of the air quality information. A compensation value may be set for the usage time of the terminal. For example, after the terminal is used for 1 year, set the compensation value to 2%; after the terminal is used for 2 years, set the compensation value to 4%. Air quality sensors are affected by temperature. Different temperatures will cause errors in the detection data of the air quality sensor. Therefore, obtaining the compensation value of the air quality information may specifically include the following steps:

Obtain the temperature inside the terminal;

The compensation value of the corresponding air quality information is obtained according to the temperature.

In a specific application, the terminal is provided with a temperature sensor. The temperature inside the terminal can be acquired through a temperature sensor. The corresponding relationship between the temperature and the compensation value may be preset and stored in the terminal, and the corresponding relationship may be a mapping table between the temperature and the compensation value. The compensation value can be a specific value or a percentage. For example, the compensation value is 1% when the temperature is 30°, the compensation value is 2% when the temperature is 60°, and the compensation value is 3% when the temperature is 90°. After the temperature inside the terminal is obtained, the compensation value of the corresponding air quality information is obtained according to the corresponding relationship between the temperature and the preset.

The air quality information is then corrected using the compensation value to obtain corrected air quality information. The way of correction may be to add the compensation value to the acquired air quality information. For example, when the internal temperature of the terminal is 60° and the obtained air quality information is 100 (PM2.5 value), the compensation value is 2%. Adding this compensation value to the obtained air quality information can obtain the corrected Air quality information is 120.

S104. Display corresponding prompt information on the terminal according to the air quality information.

Specifically, after the air quality information of the environment where the terminal is located is acquired, corresponding prompt information is displayed on the terminal according to the air quality information. If the air quality information is corrected after step S103, corresponding prompt information is displayed according to the corrected air quality information. For example, the PM2.5 value can be displayed on the display screen of the terminal. The manner of displaying the prompt information is not limited to displaying on the display screen of the terminal, and may also be displayed in other manners. For example, the prompt information is displayed through an LED (Light Emitting Diode) breathing light on the terminal.

The PM2.5 value can directly reflect the air quality condition. However, for users, it is not intuitive enough to use the PM2.5 value for prompting. The information that users want to know is more intuitive information such as "excellent", "good", "slightly polluted" and "moderately polluted". Therefore, displaying corresponding prompt information on the terminal according to the air quality information may specifically include the following steps:

Determine the pollution degree interval of the air quality according to the air quality information;

Obtain corresponding prompt information according to the pollution degree interval;

Display the prompt message on the terminal.

Specifically, the air quality information (PM2.5 value) may be divided into multiple pollution degree intervals in advance. For example, it can be divided into multiple pollution degree intervals such as [0, 35), [35, 75), [75, 115), [115, 150). After the air quality information is obtained, the pollution degree interval of the air quality is determined according to the air quality information. For example, if the air quality information is 100, it can be determined that the pollution degree interval of the air quality is [75, 115). The corresponding relationship between the pollution degree interval and the prompt information can be set in advance. For example, the prompt information corresponding to the pollution degree interval [0, 35) is "excellent", the prompt information corresponding to [35, 75) is "good", the prompt information corresponding to [75, 115) is "slightly polluted", [ 115, 150) the corresponding prompt information is "moderate pollution". After determining the pollution degree interval of the air quality, the corresponding prompt information is obtained according to the pollution degree interval and the corresponding relationship, and then the prompt information is displayed on the display screen of the terminal.

In one embodiment, the prompt information can be displayed by lighting up LEDs on the terminal in different colors. For example, the prompt information corresponding to the pollution degree interval [0, 35) is preset as LED green light flashing slowly, the prompt information corresponding to [35, 75) is LED green light flashing quickly, and the prompt information corresponding to [75, 115) is LED orange light. The light is flickering, and the prompt information corresponding to [115, 150) is that the red LED light is flickering. After the pollution degree interval of the air quality is determined, the corresponding LED light prompt information is obtained according to the pollution degree interval and the corresponding relationship, and then the LED light is lit according to the LED light lighting mode in the prompt information.

During specific implementation, the present invention is not limited by the execution order of the described steps, and some steps may be performed in other orders or simultaneously if no conflict arises.

It can be seen from the above that the method for detecting air quality provided by the embodiments of the present invention adopts the method of obtaining the environment information of the environment where the terminal is located; judging whether the terminal is in an open environment according to the environment information; if the judgment result is yes, then obtaining the environment information of the terminal. The air quality information of the surrounding environment; according to the air quality information, corresponding prompt information is displayed on the terminal. In this solution, when it is judged that the terminal is in an open environment, the air quality information of the environment where the terminal is located is obtained, and a prompt message is displayed on the terminal. The terminal only obtains the air quality information of the environment when it is in an open environment. Compared with the existing technology, it no longer detects the air quality through fixed monitoring points, but can detect the real-time air quality of the environment where the terminal is located. quality, thereby improving the accuracy of detecting air quality.

As shown in Figure 2, the method for detecting air quality, the specific process can be as follows:

S201. Acquire the ambient light intensity of the environment where the smartphone is located.

In a specific application, a light sensor is integrated on a smart phone. The ambient light of the environment where the smartphone is located is detected by the light sensor, and a corresponding electrical signal is generated. The electrical signal can be a current signal or a voltage signal. The smartphone processes this electrical signal to obtain the ambient light intensity of its environment.

S202. Determine whether the ambient light intensity is greater than a preset ambient light intensity.

Specifically, the preset ambient light intensity is a light intensity value pre-stored in the smart phone. For example, the preset ambient light intensity may be 100cd (candela). After obtaining the ambient light intensity, call the preset ambient light intensity stored in the smartphone, and compare the acquired ambient light intensity with the preset ambient light intensity to determine whether the ambient light intensity is greater than the preset ambient light intensity .

In some embodiments, the above steps S201 and S202 may also be replaced by the following steps:

Obtain the distance between the smartphone and the closest object to the smartphone;

It is judged whether the distance is greater than a preset distance.

In a specific application, a distance sensor is integrated on the front of the smart phone (the surface where the display screen is located). The distance sensor includes but not limited to an infrared sensor, an ultrasonic sensor, and a capacitive proximity sensor. The smart phone detects the distance between the smart phone and the closest object to the smart phone through the distance sensor, and generates a corresponding electrical signal. The electrical signal can be a current signal or a voltage signal. The smartphone processes the electrical signal to obtain the distance between the smartphone and the closest object to the smartphone.

The preset distance is a distance value pre-stored in the smartphone. For example, the preset distance may be 0.2m. After the smartphone acquires the distance to the object closest to the smartphone, it calls the preset distance stored in the smartphone, and compares the acquired distance with the preset distance to determine whether the distance is greater than the preset distance. Set distance.

In a specific application, an air quality sensor is provided in the smart phone. When the judgment result in S202 is yes, the air quality information of the environment where the smart phone is located is acquired through the air quality sensor. The air quality information may be the content of fine particulate matter (PM2.5) in the air.

Specifically, the air quality sensor may include an infrared transmitter and an infrared receiver. The infrared rays emitted by the infrared transmitter irradiate air dust (air containing fine particles), and then reach the infrared receiver. After the infrared receiver receives the infrared rays, it generates corresponding electrical signals. When the content of fine particles in the air is different, the intensity of infrared rays received by the infrared receiver is also different, and the electrical signals generated are also different. Based on this electrical signal, the smartphone calculates the corresponding concentration of fine particulate matter, namely the PM2.5 value.

S204. Acquire the temperature inside the smart phone.

For example, the compensation value is 1% when the temperature is 30°, the compensation value is 2% when the temperature is 60°, and the compensation value is 3% when the temperature is 90°. After the temperature inside the smart phone is obtained, the compensation value of the corresponding air quality information is obtained according to the corresponding relationship between the temperature and the preset.

S206. Correct the air quality information according to the compensation value to obtain corrected air quality information.

In specific applications, air quality sensors are affected by temperature. Different temperatures will cause errors in the detection data of the air quality sensor. Therefore, it is necessary to correct the air quality information obtained by the air quality sensor.

After the smart phone acquires the compensation value, the compensation value is used to correct the air quality information, so as to obtain the corrected air quality information. The way of correction may be to add the compensation value to the acquired air quality information. For example, when the internal temperature of the smartphone is 60°, the obtained air quality information is 100 (PM2.5 value), and the compensation value is 2%. Adding this compensation value to the obtained air quality information can obtain the corrected The air quality information is 120 for .

S207. Determine the pollution degree interval where the air quality is located according to the corrected air quality information.

Specifically, the air quality information (PM2.5 value) may be divided into multiple pollution degree intervals in advance. For example, it can be divided into multiple pollution degree intervals such as [0, 35), [35, 75), [75, 115), [115, 150). After the air quality information is obtained, the pollution degree interval of the air quality is determined according to the air quality information. For example, if the acquired air quality information is 100, it can be determined that the pollution degree interval of the air quality is [75, 115).

S208. Obtain corresponding prompt information according to the pollution degree interval.

Specifically, the corresponding relationship between the pollution degree interval and the prompt information may be preset. For example, the prompt information corresponding to the pollution degree interval [0, 35) is "excellent", the prompt information corresponding to [35, 75) is "good", the prompt information corresponding to [75, 115) is "slightly polluted", [ 115, 150) the corresponding prompt information is "moderate pollution".

For example, the prompt information corresponding to the pollution degree interval [0, 35) is preset as LED green light flashing slowly, the prompt information corresponding to [35, 75) is LED green light flashing quickly, and the prompt information corresponding to [75, 115) is LED orange light. The light is flickering, and the prompt information corresponding to [115, 150) is that the red LED light is flickering.

After determining the pollution degree interval of the air quality, the corresponding prompt information is obtained according to the pollution degree interval and the corresponding relationship.

S209, displaying the prompt information on the smart phone.

Specifically, after the prompt information is acquired, the prompt information is displayed on the smart phone. For example, when the acquired prompt information is "slightly polluted", the prompt information is displayed on the display screen of the smart phone. The obtained prompt information is that when the LED orange light is blinking, light up the LED light on the smart phone in orange.

During specific implementation, the present invention is not limited by the execution order of the described steps, and some steps may be performed in other orders or simultaneously if no conflict arises.
