摘要
用三菱FX系列的PLC设计十字路口带倒计时显示的交通灯控制系统的硬件系统和软件系统设计。该交通灯控制系统在各路口有固定的工作周期,并用七段数码管倒计时显示相应灯的剩余时间,而且在道路拥挤时中控中心能智能调节交通灯工作周期。
This paper describes the use of the Mitsubishi FX series PLC to design a crossroads traffic lights with countdown display,and introduces the design of hardware and software systems. Traffic light control system functions can be achieved as follows: the fixed duty cycle for each intersection,and with seven-segment LED display countdown time remaining relevant lamp,but also the duty cycle of the traffic lights can be adjusted intelligently when the road congestion in the control center.
