基于Matlab/GUI的地铁车辆试验数据分析系统

On Metro Vehicle Test Data Analysis System Based on Matlab/GUI

针对地铁列车制动试验数据处理量较大,人工处理步骤繁琐、耗时较长、过程易错等问题,开发了基于Matlab/GUI的地铁车辆数据分析系统,解决了快速读取数据、制动过程判断的算法问题,实现了数据可编辑式修正预处理、数据读取、数据单曲线绘图和多曲线绘图、有效制动次数的统计、制动过程车轮和闸瓦温度峰值的提取以及自动生成报表等功能。通过测试分析与验证结果表明,该系统实现了任意时间区段的列车速度、加速度、踏面温度、车轮温度、制动缸压力等曲线的绘制及报表的自动生成,系统可靠、高效、简便,数据处理精度保持与原始数据一致。

Aiming at problems of huge amount of data on metro vehicle brake test, low efficient manual processing and error prone process, a programming language is developed based on Matlab/GUI method, it could solved problems like quick data reading and algorithmic of determination during the braking process, achieve functions of data pre-processing, data read, multi-curve and single-curve chart, and statistics collection of effective braking numbers, extract the peak temperature of wheel and brake shoes, generate report automatically. The test and analysis results show that this system could achieve automatic chart generation of velocity, acceleration, tread temperature, wheel temperature, pressure curve of brake cylinder at any time zones, the data processing is precise and in accordance with the initial data.
