摘要
研究了以AT89C5 1单片机为核心的一种城市 6路制交通信号灯控制仪的软硬件设计 ,以及在提高其可靠性和抗干扰等方面所采取的措施 .实际运行的结果表明 ,该控制仪采用DS12 887和X2 5 0 4 5等集成芯片 ,简化了系统电路 ,解决了系统死机和数据易丢失的问题 ,达到了交通信号控制的各项性能指标要求 .
Soft and hard ware design of an urban traffic light controller with six channels is investigated by taking single chip microcomputer AT89C51 as its kernel and the measures employed to improve its reliability and anti interference ability are investigated, also. It is proved by practical application of this system that its electronic circuit is simplified by using the integrated circuit chips DS12887 and X25045 and the problems such as drop out of system data, deadlock of computer, etc are solved successfully, so that the performance indices of traffic light controlling are realized.
