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.
