"基于C51单片机的智能校园照明控制系统设计与实现"

楼 intelligent lighting control system, including daylight intensity measurement circuit, pyroelectric infrared human body measurement circuit, digital adjustable electronic ballast and lamps and supporting software. The system uses C51 as the control core, communicates with the PC through RS2485 communication interface and RS2232/485 circuit, realizes the monitoring of the working status and setting of the working parameters of each classroom, and selects the upper computer to realize the network management of the lighting system of each classroom, achieving the goals of intelligent control and energy saving. Each classroom and other places have separate lighting control, so if there is a problem with the lighting system in one place, it will not affect the normal lighting control in other places. The lighting management of each lighting place combines intelligent control with manual emergency control. In the central control room, the lighting of each place can be monitored and controlled in real time, and automatic lighting scene switching can be realized to meet the lighting needs of various lighting places in the school. The design of the system realizes the perfect combination of intelligent control and green lighting, saving energy while providing a good study and office environment for students and teachers, beautifying the campus, and improving the management level of the school. Test results show that the system meets the design technical requirements, with dimming error less than 5%, meeting the lighting requirements of teaching buildings.
