摘　　要：为满足复兴号系列中国标准动车组大批量生产需求,简化测试人员操作,依据牵引控制单元(Traction Control Unit,TCU)例行试验项点,并参考原手动测试台测试原理,设计研发了一套牵引控制单元自动化测试系统。该自动化测试系统硬件以PXI测控计算机为核心,配合外部测量设备和信号产生设备;测试序列使用LabVIEW语言编程;为减少测试时间,充分利用多核CPU资源,对测试序列进行并行化处理。该自动化测试系统已在复兴号350公里中国标准动车组TCU上进行了验证,测试结果表明该测试系统能大幅缩减测试时间、准确识别故障点、实现测试报告的自动生成,具有较强的可靠性和实用性。In order to meet the mass production demand of Fuxing series of Chinese Standard EMUs and simplify the operation of testers,a set of automatic test system for traction control unit(TCU) is designed according to the routine test items of TCU and the test method of original manual test bench.The hardware of the automatic test system is based on PXI measurement and control computer,with external measuring equipment and signal generating equipment;the test sequence is programmed by LabVIEW language.In order to reduce the test time,the test sequence is parallel processed to fully use of CPU resource.The test results show that the automatic test system can greatly reduce the test time,accurately identify the fault points,and automatically generate test reports.This automatic test system has strong reliability and practicability.
