PLC programmable controller is based on microprocessor,combines with advanced industrial control equipment:computer,automatic control and communication,etc.With simple structure,simple programming,stable and reliable work characteristics,it is widely used in production and life.PLC,robot and CAD/CAM are the three pillars of modern industrial automation.PLC has high adaptability to the working environment,and is widely used in traffic light control,which can effectively reduce the queuing time and achieve the purpose of scientific management.EDA technology is used to simulate intersection signal light flashing and traffic flow,and the application of programmable logic controller in signal light control is demonstrated.Through writing the configuration program,people have a deeper understanding of the use of PLC and MCGS.Through PLC development,managers can better use PLC to collect and control field information from system design,ladder diagram design to configuration design and to field testing,and fully grasp the PLC design process,so as to provide reference for engineering project product development and design.
