The air pressure sensing module 110 is configured to sense the air pressure value of the indoor space and transmit the air pressure value to the processing module 130. In the present invention, the air pressure sensing module 110 is typically a pneumatic sensor for sensing a change in air pressure in the indoor space. In an indoor environment, due to the environment The space is limited, so that during the opening or closing of the window or gate in the room, air is caused to flow, thereby causing a change in the air pressure value of the indoor space. The air pressure sensing module 110 is disposed at a position close to a door or window in the room. When the door or window is opened or closed, the surrounding air is caused to flow, and the air pressure sensor of the air pressure sensing module 110 instantaneously collects the air pressure value of the surrounding environment. The sensed air pressure value is sent to the processing module 130.

In the present invention, the sound sensing module 120 is generally a sound sensor for sensing changes in sound voiceprints and frequency values in the indoor space. The sound sensing module 120 is disposed at a position close to a door or window in the room. When the door or window is opened or closed, a sound may be generated, and the sound sensor of the sound sensing module 120 instantly collects the sound voiceprint of the surrounding environment and The frequency value is sent to the processing module 130 by the sensed voice voiceprint and frequency values.

When entering the work environment for the first time, the sound sensing module 120 determines the current working mode through the voiceprint analysis algorithm tool. When the working model of the current indoor environment matches the device pre-learning or the pre-learned model of the server, the corresponding model is loaded; when the working model of the current usage environment does not match or is not established, the model of the service pre-learning enters The voiceprint learning mode collects the door and window switch information in this embodiment, establishes a voiceprint model, and uploads it to the server to build a model.

The processing module 130 is configured to comprehensively compare the received air pressure value and the voice voiceprint and the frequency value with a preset threshold to determine whether the closed state of the door and window at the designated position in the room changes.

In the present embodiment, the database unit 131 includes a barometric data library component 1311 and a sound data library component 1312. The barometric data library component 1311 is used to collect a type feature sample that causes the air pressure to change due to the door and window switch, and the air pressure is changed for the collected door and window switch. The type feature samples are trained to obtain a database of barometric data samples. The sound database component 1312 is configured to collect the voiceprint and frequency type feature samples of the door and window switch, and train the collected window and window switch voiceprint and frequency type feature samples to obtain a sound data sample database.

The receiving unit 132 is configured to receive data sent by the air pressure sensing module and the sound sensing module. The comparison unit 133 is configured to compare the received air pressure value and the voiceprint and frequency values with corresponding comparison data in the database. The output unit 134 is configured to output the comparison result to the communication module 140.

The communication module 140 is configured to transmit the determination result of the processing module 130 to the closed state of the indoor designated position door and window to a mobile terminal.

Specifically, when the air pressure sensor of the air pressure sensing module 110 senses the air pressure information and transmits it to the receiving unit 132, the comparing unit 133 compares the received data with a preset air pressure threshold to determine the air pressure threshold. Whether the air pressure change value reaches the air pressure preset value, and when the air pressure change value is greater than or equal to the preset air pressure direct trigger value, in this embodiment, the comparison unit 133 determines that the door and window switch state changes, and notifies the communication module 140 to upload the information. To a remote server 101, the data is analyzed by the server 101 and the result is sent to a mobile terminal. The mobile terminal is associated with a user of device 100.

When the air pressure sensor of the air pressure sensing module 110 senses the air pressure information and transmits it to the receiving unit 132, the comparing unit 133 compares the received data with a preset air pressure threshold to determine the air pressure change value compared with the air pressure threshold. Whether the air pressure preset value is reached, when the air pressure change value is less than the air pressure direct trigger value but greater than or equal to the preset air pressure joint trigger value, the comparing unit 133 causes the device 100 to enter the tracking mode, and the environment information is further changed or transmitted through the communication module.

When the sound sensing module 120 senses the audio change information, the comparing unit 133 of the processing module 130 compares the received data with a preset audio threshold, and when the difference between the two is smaller than the direct trigger value of the audio. However, when the greater than the audio is equal to the joint trigger value, the processing module 130 enters the tracking mode to track the situation in which the environmental information is further changed or The module 140 uploads the server 101 and further transmits it to the mobile terminal, notifying the user to perform a processing operation, and tracking the project.

When the pressure change information received by the air pressure sensor is compared, the value is less than the direct trigger value of the air pressure but greater than or equal to the combined pressure trigger value. At the same time, the value of the audio change information sensed by the sound sensor is smaller than the direct trigger of the audio. When the value is greater than or equal to the audio joint trigger value, in the present embodiment, the processing module 130 determines that the door and window switch status changes, notifies the communication module 140 to upload information to the server 101, and the server 101 analyzes the data and notifies the mobile. terminal.

When the processor receives the instantaneous indoor temperature exceeding the set temperature threshold, the current indoor state may be determined as a temperature abnormality, and the determination information is sent. Alert the user to the mobile terminal. For example, when the indoor space is indoors or in the vehicle interior, the processor determines that the indoor temperature is higher than the set temperature threshold, and sends an alarm signal to alert the fire or other information; when the indoor space is a container, the processor determines that the temperature inside the container is high. to Set the temperature threshold, send an alarm signal to remind the ventilation and heat, reduce the temperature inside the container; when the indoor space is the refrigerator for storing fruits, the processor determines that the temperature inside the container is higher or lower than the set temperature threshold, and sends a warning signal. Remind to cool or warm the reefer to prevent the fruit from deteriorating or being frozen.

In addition, when the method is applied to an indoor space inside a vehicle, during the traveling of the vehicle, the altitude information of the current location of the vehicle can be sensed by the air pressure sensor, and the sensed altitude information is transmitted to other externals. Car navigation device for the device. The navigation device can determine the current location of the vehicle according to the altitude information value provided by the air pressure sensor, and avoid the navigation error when the vehicle is traveling on the viaduct and similar road conditions.
