ABSTRACT

Traffic Light Control System Design Based on PLC and

KingView

ABSTRACT

With the continuous improvement of people's consumption level, private vehicles continues to increase, many people, cars, roads and less road traffic situation has been very clear, at the same time each intersection is the city road network choke points, so the intersection signal control more is important. We usually need the entire system for centralized monitoring and management, so the use of effective methods to control traffic lights is imperative. This paper details the normal operation of traffic lights, the use of models with versatile features for CPU 224 of the S7-200 series PLC for control, given the appropriate hardware wiring and ladder, the configuration by combining the king and PLC real-time control of traffic lights on the crossroads, with an intuitive control program variable, easy to learn.

Kingview software is by Beijing asiacontrol Technology Development Co., Ltd. developed industrial level software, is the first application in China in the fields of aviation and aerospace domestic configuration software, has the development of simple, good, has the advantages of higher reliability growth. Application of Kingview software, so the control of dynamic monitoring system of traffic lights at the crossroads, and with the PLC to achieve serial communication, so as to realize the real-time control of the traffic lights at the crossroads. [1]

The main topic is the configuration screen and the laboratory experiment platform of single intersection traffic lights and the corresponding design, realizes the Kingview and PLC in the experiment of the connection.

Key words: Kingview;PLC;Traffic Lights; Control Systems
