上海轨道交通2号线车载安全数据监控系统的研制

摘要

介绍了一种监控上海轨道交通2号线安全运行数据的系统.其分为车载记录板卡和PC端分析回放软件两个部分.车载板卡具有数据记录量大,记录信息全面,ATC(列车自动控制)设备掉线重连等特点；回放分析软件能够方便、快速地分析数据,且能图形化显示.车载板卡直接使用110V机车直流电源,尺寸符合列车车头机架结构,安装方便,解决了车载ATC设备数据记录量小、记录数据不全、分析数据困难、不直观等不足.%A system is developed to record and analyze the on-board data of Line 2, it features the function of huge data recording, comprehensive data information and analysis as well as the playback capacity. It can be divided into two parts:the recording board on the vehicle; the data a-nalysis and playback software on PC. The former directly uses 110 VDC power supply of the vehicle and its size could meet the train's frame structure. This system could solve the problem of low data recording capacity and the difficulty in data analyzing, thus it will improve the efficiency of the maintenance of rail transit.
