摘　　要：列车运行监控装置(LKJ)是我国现阶段普速铁路应用最为广泛的车载设备之一,随着铁路运输需求的不断提升,作为保障行车安全,提高运输效率的关键设备,LKJ设备变得愈发重要。为解决LKJ设备人工测试过程工作量大、效率低下,难以找寻故障原因等问题,设计一种LKJ自动测试平台并对其关键技术进行研究。自动测试平台基于传统的人工测试流程进行优化,采用图形化方式生成测试用例,设计信号适配单元模拟设备运行条件,增加人机交互单元简化测试操作,基于Robot Framework自动测试框架及故障分析专家系统自动执行测试并给出故障原因,实现可无人值守的自动化测试。通过LKJ-15型设备及实验室仿真环境进行验证,结果表明,自动测试平台可取代传统仿真测试中部分人工操作,对故障现象进行分析给出指导意见,有效提升了测试效率。Train operation monitoring device(LKJ)is one of the most widely used on-board equipment in Chinese current ordinary speed railway.With the continuous improvement of railway transportation demand,as the key equipment to ensure traffic safety and improve operation efficiency,LKJ equipment is becoming more and more important.In order to solve the problems such as heavy workload,low efficiency and difficulty in finding the fault in the manual test process of LKJ equipment,an LKJ automatic test platform is designed and key technologies are studied.The automatic test platform fulfills optimization based on the traditional manual test process,generates test cases in a graphical manner,designs signal adaptation units to simulate the operating conditions of the equipment,adds humancomputer interaction units to simplify the test operation,automatically executes the test based on the Robot Framework automatic test framework,calls on fault analysis expert system to give the cause of the fault,so as to realize the unattended automatic test.Through the verification of LKJ-15 equipment and laboratory simulation environment,the verification results show that the automatic test platform can replace some manual operations in the traditional simulation test,provide guidance for the analysis of fault phenomena,and effectively improve the test efficiency.
