Urban rail vehicle PIS system comprehensive performance test method and system

The invention provides an urban rail vehicle PIS system comprehensive performance test method and system, and relates to the technical field of digital information transmission, and the method comprises the steps: constructing a test scene set through big data based on the read urban rail vehicle PIS system node information, carrying out the scene adaptation construction to generate an adaptive scene set, obtaining a master node and a slave node through node identifiers, and carrying out the matching of the master node and the slave node; a signal detection device is arranged through system node information, scene signal emission is carried out through a master node or a slave node, the signal detection device receives the scene signal and then generates first performance test information with an adaptive scene set, and a terminal responds to video acquisition to generate second performance test information; according to the urban rail vehicle PIS performance testing method and device, the technical problem t
