摘　　要：根据十字路口交通灯的一般控制要求,采用寄存器整体赋值法设计控制程序。首先进行时序划分,再基于I/O分配进行状态分析,确定整体赋值指令系列,然后编制PLC梯形图程序。通过在三菱FX系列芯片与交通灯控制模块上验证程序,该系统满足十字路口交通信号灯的控制要求,而且基于寄存器赋值法设计的十字路口交通信号灯的PLC梯形图程序更易于理解、阅读和修改。According to the general control requirements of intersection traffic lights,the whole register assignment method is used to design the control program.First of all,the time sequence is divided,and then the state analysis is carried out based on I/O assignment to determine the whole assignment instruction series,and then the PLC ladder diagram program is compiled.By verifying the program on Mitsubishi FX series chip and traffic light control module,the program meets the control requirements of intersection traffic lights,and the PLC ladder diagram program of intersection traffic lights based on register assignment method is easier to understand,read and modify.
