Abstract
PLC programmable logic controller is a microprocessor as the foundation, a new type of industrial control devices puter technology, automatic control technology munication technology developed from the. It has the advantages of simple structure, easy programming, high reliability, has been widely used in automatic control of industrial process and the location of to statistics, the programmable controller is the most widely usedequipment in the industrial automation devices. The expert thinks, the programmable controller will e one of the major means of industrial control and the important infrastructure, PLC, robotics, CAD/CAM will e the three pillars of industrial production. Since PLC has strong adaptability to environment, and its internal timer is very rich in resources, the progressive "signal current widespread use of" precise control, especially for the control of multi fork can be easily achieved. Therefore the PLC is now increasingly used in traffic lights system. At the same time, work also has its own functions, will be on the road with a signal of a LAN unified dispatching managemen
