用于轨道交通车载电源性能自动化评测系统

为解决轨道车辆车载辅助电源通用检测设备缺乏的问题，设计搭建了一种新型的轨道交通车载电源性能 指标评测的自动化集成测试平台。该平台以上位机软件作为主控制器，综合运用计算机控制、变频调压、传感 器测量、网络通讯等技术，模拟动车实际工作环境，对已有硬件设备进行整合和集成，将之搭建构成统一的硬 件测试平台。并在此硬件平台的基础上设计开发软件测控系统，提升实验室对车载电源寿命及可靠性检测的 工程研究能力，为动车组对相应产品的高级检修提供测试数据作为检修依据，节省了检测资源，提高了检测 效率。

Automatic Performance Evaluation System for On-board Power Supply of Rail Transit#br#

In order to solve the problem of the lack of general detection equipment for on-board auxiliary power supply of rail vehicles，we design a new automatic integrated test platform for evaluating the performance index of on-board power supply in rail transit． The software of this platform is the main controller，and this paper synthetically uses computer control，frequency conversion and voltage regulation，sensor measurement，network communication and other technologies to simulate the working environment of electric vehicles，integrates the existing hardware equipment，and builds a unified hardware testing platform． On the basis of this hardware platform，the software measurement and control system is designed and developed to enhance the engineering research ability of the laboratory for the life and reliability detection of on-board power supply，and provide test data for the advanced maintenance of the corresponding products as the basis for the maintenance，which saves the testing resources and improves the detection efficiency．
