The invention discloses a train-control vehicle-mounted ATP equipment integrated intelligent operation and maintenance method and system, and relates to the field of railway communication and signaling related to CTCS-2 / CTCS-3 grade train-control vehicle-mounted equipment. By the adoption of the train-control vehicle-mounted ATP equipment integrated intelligent operation and maintenance method and system, collecting and sending of recorded data related to ATP equipment can be completed in real time, analysis is completed automatically in a very short time after faults occur and warning information is generated, and analysis results are synchronously pushed to maintenance personnel, so that it is convenient to conduct equipment maintenance or emergency treatment. The purpose is achieved that the recorded data of various modules of the vehicle-mounted equipment is automatically downloaded, in combination with a big-data intelligent analysis technology, the analysis results are given in a relatively short time after the faults occur, the operation maintenance personnel are guided to make the most appropriate response or treatment at once, and the influence of the faults on on-site operation is reduced.
