交通信号灯的实验画面设计

Experimental Picture Design of Traffic Lights

本设计采用西门子S7-200smart PLC和西门子的触摸屏作为交通信号灯实验画面设计的基本硬件,然后从硬件设计、PLC控制程序的软件设计两方面出发,详细介绍了设计原理、硬件接线、时序图及触控画面,实现了对交通信号灯的运行可靠控制,达到预期的设计目的。

In this design,Siemens S7-200 smart PLC and Siemens touch screen are used as the basic hardware for the design of the traffic signal experimental screen.Then,starting from the hardware design and the software design of the PLC control program,the design principle,hardware wiring,software ladder diagram,timing diagrams and touch screens realize reliable control of the operation of traffic lights and achieve the expected design goals.
