[0006] S2: Determine several photosensitive points in the room and arrange photosensitive sensors;

[0007] S3: Determine the indoor temperature sensor;

[0008] S4: The photosensitive sensors arranged at several photosensitive points collect the light brightness of each photosensitive point and output it to the controller through Zigbee;

[0009] S5: The controller judges according to the set value, opens or closes the corresponding left and right curtains, adjusts the air conditioner temperature, and outputs a brightness adjustment instruction to the driver corresponding to the lamp group controlled by each controller to adjust the lights, completing the adjustment of the indoor light brightness. If no human figure movement is detected by the camera within 8 minutes, all electrical equipment is turned off.

[0010] As an improvement, in the above S1, the infrared human body sensor of the camera monitors the personnel activities in the classroom. When someone enters the classroom, the lights are automatically turned on or enhanced; when the classroom is empty, the lights are automatically dimmed or turned off.

[0011] As an improvement, in the above S2, the photosensitive sensor is used to sense the indoor light intensity, and the light brightness is automatically adjusted according to a preset algorithm. When the indoor light is weak, the lights are automatically enhanced; when the indoor light is strong, the lights are automatically dimmed to ensure that the indoor illumination is maintained at an appropriate level.

[0013] As an improvement, in S4, the classroom lighting system is connected to the remote monitoring platform through wireless communication technology (Zigbee) to achieve remote monitoring and management. The administrator can view the classroom lighting status in real time through the mobile phone APP or computer software, perform remote control and management, improve the management efficiency, and at the same time, the coordination controller can judge according to the set value and automatically complete the adjustment of the indoor equipment unit.

[0014] The present invention has the following advantages: The method uses photosensitive sensors installed at the upper left, upper right, lower left, and lower right points of the traditional blackboard to read the sensor data by a 51 single-chip microcomputer, analyze and judge the light intensity, and adjust the indoor light brightness in a zoned and grouped manner for the lights. The light intensity and frequency of each light group can be adjusted step by step. At the same time, the curtains on both sides are controlled. If the value read by the left sensor is greater than that of the right sensor, the single-chip microcomputer controls the left curtain to close (similarly for the right side). If the values of the four sensors are all lower than the standard value, the single-chip microcomputer controls the classroom lights to turn on and the curtains to open, reducing the irritation to the eyes caused by strong light reflection, and constructing a comfortable teaching and learning environment for teachers and students, which can effectively reduce the harm of indoor lighting problems to students' eyesight; the temperature sensor detects the temperature, and the air conditioner switch is controlled by the control unit to adjust the temperature; when the students leave school, if the front cloud camera in the classroom detects that there is no human figure movement within two minutes, the classroom automatically turns off the lights and shuts down electrical equipment such as water heaters to achieve linkage.
