摘要
介绍了基于单片机技术、CAN总线技术、红外遥控技术等设计的智能交通信号灯控制系统,详细介绍了系统结构组成原理及硬件电路设计方法.系统采用单片机AT89C51为核心控制器处理车流信号,红外接收器接收来自发射器的红外信号,经解调后输入单片机进行处理,同时单片机与CAN总线控制器SJA1000构成CAN总线通信系统进行数据传输.实现了根据车流、遥控及总线PC机三种方式的分布式交通信号灯智能控制系统设计.
Smart traffic signal lights control system was designed, microchip technology ,CAN BUS technology and Infrared remote control technology are employed in this system. Its composition principle and the methods of hardware design were introduced. Vehicle flux signal was processed with the core of AT89C51. Infrared signal coming from launcher was received by infrared receiver microcontroller, The signal was treated by microchip after demodulation. The microchip controls the CAN BUS controller SJA1000 to structure CAN BUS communication system to transmit the data. The designator of distributed traffic signal light smart control system was carried out by three control styles of Vehicle flux, remote and BUS PC.
