摘要在现代社会中，城市轨道交通的服务水平不断提高，我国的轨道交通事业发展迅速，地铁已经成为人们生活中重要的交通工具之一。对乘客安全、车站环境、节能等方面的要求也在相应的不断提高。屏蔽门系统正是因为城市轨道交通的这些需要而产生的。它是设置在城市轨道交通车站站台边缘的一种安全装置，将列车与车站站台候车区域隔离开来，在列车到达和出发时可自动开启和关闭，为乘客营造了一个安全、舒适的候车环境，因此地铁屏蔽门系统成为当前轨道交通发展的热点问题之一。本文从屏蔽门系统的基本特点和运行模式开始介绍，之后对地铁屏蔽门控制系统的硬件组成进行了研究。66796

Title: platform screen door gated unit hardware design

Abstract

In modern society, urban rail transit service levels continue to improve, Our country rapid development of rail transport, metro has become an important means of transport in life one. Safety of passengers, station environment, energy and other requirements are also increasing accordingly. PSD system precisely because of these urban rail transport needs arising. It is set at the edge of urban rail transit station platform as a safety device, the train and the station platform waiting area to isolate the train arrival and departure can be automatically turned on and off, for passengers to create a safe and comfortable waiting environment Therefore PSD rail transit system has become the current hot topic of development. In this paper, the basic characteristics of PSD system and operation mode begins introduced after the right PSD control system hardware components were studied.

This paper completes the hardware circuit shielding door control system design, including power system, control system and the design of drive circuit. Control unit LPC2129 microcontroller core, the design of the input output interface circuit, an external memory circuit and the watchdog circuit; Driver module to complex programmable logic device EPM2410T100 as the core, the design of the power drive circuit, over current detection circuit.

Keywords: PSD system； Microcontrollers；Programmable Logic Devices
