摘要
为达到教学楼照明智能、节能的目的,设计了基于C51单片机的教学楼智能照明系统,包括日光强度测量电路、热释电红外人体测量电路、遥控发送接收电路、数字可调光电子镇流器和灯具及配套的软件。系统以C51为控制核心,通过RS-485通信接口及RS-232/485转接电路完成与PC机通信,实现对每个教室工作状态的监控及工作参数的设置。测试结果表明,系统达到设计技术指标,调光误差低于5%,满足教学楼照明要求。
In order to achieve the intelligent lighting and energy-saving in academic buildings, the intelligent lighting system for classroom is designed based on C51 single-chip, including the measurement of sunlight intensity circuit, pyroelectric infrared body measurement circuits, the remote control to transmit and receive circuit, the digital adjustable electronic ballast, lamp and matching software. The system is controlled by C51, through the RS-485 and RS-232/485 communication interface with the PC adapter circuit to complete communication, realizing monitoring the state of every classroom and setting of operating parameters. System testing shows that it meets the design specifications, and meets the lighting requirements of academic buildings.
