Fig. 4 is a flowchart of an infrared monitoring program of a low power consumption video monitoring system according to a third embodiment of the control method of the low power consumption video monitoring system of the present invention. The method is applied to a low-power-consumption video monitoring system comprising an infrared detection module. The infrared detection module consists of a probe, a conversion element and an amplifying circuit and is used for detecting the movement of a human body. The infrared detection module can be a pyroelectric sensor module or other human body infrared detection modules. The specific control method in this embodiment includes the following steps:
step 401, the infrared detection module detects that there is a movement of a human body, and generates a corresponding detection signal. The detection range of the infrared detection module is limited, and when a person moves in the detection range, the probe of the infrared detection module refracts infrared rays radiated by a human body to the surface of the conversion element; the conversion element absorbs the infrared rays refracted on the surface thereof and converts the infrared rays into electrical signals; since the electrical signal converted by the conversion element is weak, the electrical signal needs to be transmitted to an amplification circuit for amplification and output. Therefore, the infrared detection module finally outputs an amplified electric signal.
And step 402, the infrared detection module sends a detection signal to the video acquisition device through the serial port. Specifically, a conversion circuit of the infrared detection module outputs an amplified electric signal, and the electric signal is sent to a video acquisition device through a serial port or sent to a network communication device. Generally, the infrared detection module is connected with other devices or modules through TTL serial ports. The first low-power-consumption communication module and the second low-power-consumption communication module are ZigBee modules or Bluetooth modules.
And 403, the video acquisition equipment receives the detection signal and sends a reminding instruction to the user terminal. Specifically, after the video acquisition device receives the amplified electric signal through the serial port, the video acquisition device converts the electric signal into a reminding instruction which accords with a ZigBee protocol or a Bluetooth protocol, and a second low-power-consumption communication module of the video acquisition device sends the reminding instruction to a terminal of a user.
If the infrared detection module sends the detection signal to the network communication equipment, the network communication equipment converts the detection signal into a reminding instruction which accords with a ZigBee protocol or a Bluetooth protocol, and sends the reminding instruction to a terminal of a user through the first low-power-consumption communication module. And step 404, the user checks the monitoring video according to the reminding message of the terminal. The terminal receives the reminding instruction through a wireless receiving and sending device of the terminal, converts the reminding instruction into reminding information and displays the reminding information through a display device. The user can take further measures according to the reminding information. The method comprises the steps of inputting a request viewing instruction at a terminal to view a monitoring video or request help of a property management department and the like, wherein the input mode of the request viewing instruction comprises one or more of sending a request viewing short message, dialing wakeup, clicking a cat eye control interface entering the terminal, clicking a cat eye button of a mobile phone APP, and inputting a request viewing command at a WeChat public number or the APP. Certainly, the system can also be preset, so that the video acquisition equipment not only sends a reminding instruction to the terminal according to the ZigBee information or the Bluetooth information, but also converts the ZigBee information or the Bluetooth information into a starting signal to be sent to the camera and the second high-speed communication module so as to start the camera to acquire a video, and starts the second high-speed communication module to send acquired video data to the terminal or send the video data to the server for storage, so that a user can check the monitoring video in time while receiving the reminding. Or the terminal receives the reminding instruction and receives a confirmation instruction input by the user, the confirmation instruction is sent to the video acquisition equipment, the video acquisition equipment starts the camera to acquire the video, and the second high-speed communication module is started to send acquired video data to the terminal.
In addition, the user can set a cyclic detection mode for the infrared detection module, namely the infrared detection module detects the detection range once every several seconds or minutes, so that the infrared detector is not always in a detection state, and the power consumption of the system is reduced.
Furthermore, when the user receives corresponding reminding information through the terminal and is at home, the user can check the outdoor monitoring video shot by the camera by clicking a 'cat eye' button displayed by the indoor display screen.
In the third embodiment of the invention, because the system adopts the infrared detection technology, when the infrared detection module detects that a human body moves, the infrared detection module sends a detection signal to the video acquisition module through the serial port, and the second low-power-consumption communication module of the video acquisition module sends reminding information to a user according to the detection signal, so that the user can know the monitoring condition in time, and reliable and safe guarantee is provided for the user.
It should be understood that the above embodiments only represent the preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several changes and modifications can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the claims of the present invention.
