The teaching building management platform sends a control command or data information to the classroom terminal through the NBIOT communication system, receives data returned by the classroom terminal, and after monitoring data of the light-off condition of the classroom is obtained, managers can turn off the light of the classroom which is not turned off in a targeted manner. The parts are now described with reference to fig. 2 as follows:
referring to fig. 3, the classroom terminal includes a first power module, a photoresistor module, a first single-chip microcomputer and a data processing module, wherein the first power module converts 220V alternating current into 5V direct current to supply power to the first single-chip microcomputer, the photoresistor module and the data processing module, so that normal operation of the system is ensured. The first single-chip microcomputer controls the photosensitive resistor module and the data processing module to work through the control signal and receives information about classroom light-out conditions fed back by the data processing module and the photosensitive resistor module. Specifically, the photoresistor module is used for collecting information about the classroom light-off condition, namely when the classroom is not in the light-off, the resistance of the photoresistor becomes small under illumination, corresponding circuit information (analog quantity) is generated and output to the data processing module, the data processing module converts the circuit information into data information and outputs the data information to the first single-chip microcomputer, and the first single-chip microcomputer transmits the data to the teaching building management platform through the NBIOT communication system after receiving the data uploaded by the photoresistor module.
