摘　　要：ATP车载设备是保障列车运行控制系统正常工作的核心设备,其测试是列控系统研发过程中至关重要的一环。目前,ATP车载设备测试存在人工依赖性强、效率低、可靠性差等问题。为解决上述问题,在传统CTCS-3级列控车载设备平台的基础上,根据车载设备的操作流程,定义操作指令,并将其转化为上位机软件的操作命令,对上位机软件功能模块进行优化;将虚拟网络控制台技术与图像识别功能结合实现人机界面单元自动操控;提取JRU中车载设备采集的原始信息以及输出控制信息的记录,对测试结果进行校验;最后,利用现有ATP车载设备实验室测试序列对提出的列控车载设备自动化仿真测试方法进行验证,确保该方法可以在实际车载设备测试中得到应用。实验表明,本文提出的列控车载设备自动化仿真测试方法符合实验室测试要求,可以实现自动化测试,具有较高的准确性,同时降低测试人员的工作强度,具有一定实际应用价值。Automatic Train Protection(ATP)onboard equipment is the core equipment that ensures the normal operation of train control system,and its testing is a crucial part of the systems development.At present,the testing of ATP onboard equipment faces challenges such as high reliance on manual processes,low efficiency,and poor reliability.To address these issues,this study built on the traditional CTCS-3 level train control onboard equipment platform and defined operation instructions based on the operation flow of the onboard equipment.These instructions are then transformed into commands for the upper computer software,optimizing its function modules.The virtual network console technology was combined with image recognition capabilities to achieve automatic control of the human-machine interface.The original information collected by the onboard equipment in the Juridical Recording Unit(JRU)and the records of the output control information were extracted to verify the testing results.Finally,the proposed automated simulation testing method for train control onboard equipment was verified using existing laboratory testing sequences of ATP onboard equipment to ensure its applicability in real onboard equipment testing.The experiment shows that the proposed automated simulation testing method meets the requirements of laboratory testing,enables automated testing with high accuracy,reduces the workload of testing personnel,and possesses practical application value.
