Embodiment 1
[0012] Such as figure 1 As shown, the present invention can realize effective intelligent control of classroom lighting. Its input parameters are mainly information such as classroom light intensity, number of people and its location. When the system is powered on, the automatic and manual modes of the controller are realized through the manual / automatic switching circuit Select, the manual mode is the normal classroom working mode; in the automatic mode, when a certain light intensity is met and there are people, the lighting can be automatically turned on, and at the same time combined with the pyroelectric infrared sensor to determine the area where the personnel are distributed, to achieve specific partitions The lighting is accurately lit, and the display circuit can display the number of people in the classroom in real time. When it is impossible to determine the position of people in the classroom through the pyroelectric infrared sensor, all the lights will be turned o...
