Design of Urban Intelligent Traffic Signal Lights Based on PLC and KingView
With the improvement of China's national economic level and the increase in people's travel demand,the number of people purchasing motor vehicles has rapidly increased,leading to a significant increase of cars in China and thus increasing the carrying pressure on urban roads.Although this growth facilitates people's travel,it leads to increasingly severe congestion problems.Therefore,based on common urban traffic signal lights,the S7-1500 series controller of Siemens PLC is used as the core to control the red and green duration of urban traffic signal lights.The feasibility of the control system is verified through simulation,and the expected simulation results are obtained by debugging according to parameters.
