摘　　要：基于三菱PLC,分别采用梯形图和状态转移图两种不同编程方法对自动交通灯控制系统进行设计,并对程序进行实验验证。结果表明两种设计程序均正确合理,其中状态转移图编程方法使程序控制逻辑简化、直观、易懂、设计简单方便,对复杂顺序控制系统设计具有一定指导意义。Based on MITSUBISHI PLC,the automatic traffic light control system is designed with two different programming methods,ladder diagram and state transition diagram,and the program is verified by experiments.The results show that the two design programs are all correct and reasonable,and the state transition diagram programming method makes the program control logic simplification,intuitionistic,easy to understand,easy to design,and has certain guiding significance for the design of complex sequence control system.
