摘要：如今伴随着世界科技的飞速发展，生活节奏不断加快，轨道交通的需求与日俱增。世界各国轨道交通都面临着高峰时期客流密度大、相邻列车间隔时间短及相邻两站之间距离短等问题。尤其是当今中国正处在加速发展时期，而且庞大的人口在每天创造自己的中国梦时，都在给当今的轨道交通施加着巨大的压力。
      本论文主要研究PLC进行地铁控制运行与仿真。相对于其他的各个控制系统或是仿真系统，PLC拥有自己独特的优越性和实施性。对于整个运行环境、地铁控制可以运用step 7进行设计控制，地铁仿真界面我将用WinCC模拟。如此，操作则相对简单，编程较为容易且可重复编程、及时更改，操作性很强。而且十分经济、可靠、安全、耐用。如此研究出的项目不但可以运用于真实的地铁系统，还能用于培训地铁运行监管人员、测试地铁软件和教学实验。7116

PLC Control of Subway Operation Simulation System
Abstract: Nowadays, with the rapid development of world science and technology and the accelerating pace of life, the demand of Rail traffic grows with each passing day. The hole world railway traffic is facing with several problems like the metro passenger density in the rush hour, the short time between the two adjacent trains and the short distance between the two adjacent stations. Especially today’s China is in a period of accelerated development. The high population owning China dream is bringing a great pressure on the urban rail traffic.
    The main goal of this paper is to Study on PLC control of subway operation and simulation. Compared to other control or simulation system, PLC has its own unique superiority and practicability. For the entire operating environment and control of subway, Step 7 is used to design and control. WinCC simulate the subway simulation interface。Thus, the operation and programming are relatively simple. It also has the advantages of repeatable programming, timely change, strong operability, reliable, safe, durable and cheap. Therefore, the project can be used in subway system in real, training of supervisors, subway software testing and teaching experiment.
