"基于PLC的交通灯控制系统设计与仿真研究"

r smooth road traffic. Programmable Logic Controller (PLC) has the characteristics of strong anti-interference ability, high reliability, small size, and simple programming, and has a wide range of applications in automatic control systems. This paper studies the control of traffic lights based on Omron CQM1 PLC, fully utilizing the timing/counting, sequential control, logical operation and other functions of PLC, and introduces the control program design method for the PLC control system of traffic signals. The simulation of the traffic light control system is realized in Kingview. In the design process, the basic principles and applications of programmable controllers and Kingview were studied. The ladder diagram programming method of PLC was researched for the traffic light control program, and the visual monitoring screen simulation of traffic lights was provided in Kingview. Keywords: PLC; Kingview; traffic light This passage summarizes the content of a graduation thesis, which focuses on the implementation of a traffic light control system using PLC technology. The importance of traffic signal control system in urban traffic management is highlighted in the abstract. The use of PLC in the design and simulation of the traffic light control system is emphasized, along with the utilization of Kingview for visual representation. The abstract also outlines the key components and methods used in the research, such as the Omron CQM1 PLC and the ladder diagram programming for traffic light control. Overall, the abstract provides a comprehensive overview of the research content and the methods employed in the study.
