摘要
以PC机作为上位机,组态王软件作为上位机软件,三菱PLC作为下位机,组成一套以交通灯为被控对象的三菱PLC控制管理系统。通过对交通灯的时序分析、PLC选项、I/O分配及PLC接线等环节完成系统硬件设计;软件采用梯形图编写,实现在PC机上启动、停止、在线修改信号灯时间、紧急情况处理及夜间模式切换等功能,达到PC机与PLC的实时交互。系统画面直观,能够模拟真实的控制现场,且操控方便,为系统的实际应用提供了可靠保障。
A Mitsubishi PLC control and management system is built up for control of traffic lights,using PC as upper computer,King View as upper computer software and Mitsubishi PLC as lower computer. The system hardware design is completed through timing sequence analysis,PLC option,I / O distribution and PLC wiring. The software is compiled in ladder diagrams to perform such functions as start and stop through the PC,on-line modification of signal light time,emergency treatment and switch-over of night mode,so as to realize real-time interaction between the PC and PLC. This system with intuitive view can simulate actual control sites and is easy to operate,thus providing reliable guarantee for its actual application.
