Control System of Partition Door Based on PLC
Abstract：With the continuous improvement of people's living standards and the rapid development of science and technology, people pay more attention to the automation and humane products. City subway system is the city's air defense air defense an extremely important part. Underground civil air defense construction should take into account the need to achieve both peacetime and wartime air defense projects, comprehensive utilization. This article is about the design of the control system of automatic door, automatic door system mainly consists of a programmable controller ( PLC ), induction device, the driving device and the transmission device. In order to enhance the operation reliability of automatic door, in this paper, a S7-200 programmable controller as the core of the automatic door control system. This paper analyzes the automatic door control system design, introduces the hardware design of automatic door drive device, PLC selection, selection, induction device selection, system software design, PLC ladder diagram design, software design, debugging, hardware connection and other aspects of the content
Key words: Programmable Logic Controller；Fire door；Ladder diagram； Hydraulic system

1.1课题背景
城市地铁中的人防系统是城市人防中一个极其重要的组成部分。地铁建设应当兼顾人民防空的需要，人防工程做到平战结合，综合利用。
地铁工程平时是城市地下交通干道，战时是城市人民防空疏散干道、物资储存库、人员待蔽部或人员掩蔽部。平时各个车站、区间隧道相互连通，通车运营，战时可以隔断成相互独立的防护单元。
