detailed description

The technical idea of the present utility model is:

The pyroelectric sensor is used to detect whether there are people in the corresponding place to realize the monitoring function. The pyroelectric sensor transmits the detection information to the single-chip microcomputer: when a person is detected, the single-chip microcomputer controls and turns on the lighting system in the corresponding area; When it is time to leave the seat, the single-chip microcomputer controls and turns off the lighting system of the corresponding area. At the same time, at regular intervals, the single-chip microcomputer transmits the collected information to the computer terminal. Through the processing of the computer terminal, the corresponding processing information is displayed on the terminal display screen. Library managers can know the use of each desk in the library through the computer terminal display screen, and students can also search through the terminal to know which desk is available. It is very convenient for the library and classmates.

Below in conjunction with Figure 1 of the accompanying drawings of the description, the technical solution of the utility model will be further described in detail.

The information collection module (1) is connected to the information processing module (2), and the information processing module (2) outputs to the Internet of Things module (3) and the lighting control module (4) respectively; the pyroelectric human body of the information collection module (1) Infrared sensors (11) are set at an angle of 90° to the library seats.

The pyroelectric human body infrared sensor (11) of the information collection module (1) is connected to the single-chip microcomputer input port (21) of the information processing module (2) through an output interface (12).

The power supply (23) of the information processing module (2) is connected to a switch (24), the switch (24) is connected to the single-chip microcomputer input interface (21), and the single-chip microcomputer input interface (21) is connected to the single-chip microcomputer output interface (22).

The single-chip microcomputer output interface (22) of described information processing module (2) connects the first ZigBee module (31), and the first ZigBee module (31) connects the second ZigBee module (32), and the second ZigBee module (32) connects computer terminal The information processing module (33), the computer terminal information processing module (33) is connected to the terminal display module (34).

Brief description of the work flow of the utility model:

After turning on the power supply (24) and the switch (25), if the pyroelectric human body infrared sensor (11) detects someone, the output interface (12) is transmitted to the single-chip microcomputer input interface (21) high level, and the single-chip microcomputer output interface (23) transmits The information is given to the lighting control module (4), and the light is turned on; the pyroelectric human body infrared sensor (11) of the information collection module (1) is set to an angle of 90 ° with the library seat, so that the pyroelectric human body infrared sensor ( 11) The person on the seat can be detected without triggering the pyroelectric human body infrared sensor (11) to generate a signal because the person passes by the seat. If the pyroelectric human body infrared sensor (11) detects no one, the single-chip microcomputer output interface (22) is transmitted to the low level of the single-chip microcomputer input interface (21), and the single-chip microcomputer starts counting, and when the counting time reaches the longest time of leaving the seat stipulated by the library , the single-chip microcomputer output interface (22) transmits information to the light control module (4), and turns off the light. Simultaneously, at regular intervals, the single-chip microcomputer will collect and process the information by the single-chip microcomputer output interface (22) by serial port transmission to ZigBee module 1 (31), and ZigBee module 2 (32) receives the information of ZigBee module 1 (31), transmits to computer terminal. After processing, the terminal finally displays information such as light status and seat number on the terminal display module (34).
