To achieve compliant safety and reliability of traction,braking,and subsystems,all urban rail trains must undergo thorough manual dynamic operation tests on special dynamic commissioning lines before being put into official operation.In the commissioning process,safety issues caused by human operation error,software or hardware failure that may result in the train being unable to stop timely and precisely,affecting the test plan and delivery time of the train and causing a measure of economic loss or adverse social impact in severe cases.To cope with the above issues,this article posits an assisted safety control system of urban rail trains based on a high-precision positioning device that helps the train test scenario of the dynamic commissioning test line to enable the train dynamic commissioning test to follow a safe and orderly process.
