The invention belongs to the technical field of subway operation and maintenance, and particularly relates to an operation and maintenance diagnosis method and system for a vehicle-mounted system.
Background
The CBTC (moving block train control system) is a continuous automatic train control system realized by utilizing high-precision train positioning (independent of track circuits), bidirectional large-capacity train-ground data communication and vehicle-mounted and ground safety function processors. CBTC is the mainstream technology adopted by the subway signal in China at present.
Compared with the traditional train control system based on the track circuit, the mobile block train control system has the characteristics of easy interconnection, automation of dispatching and commanding, short engineering construction period, high system safety performance, large passing capacity, less trackside equipment, capability of realizing mobile block, strong system compatibility and flexibility and the like due to the adoption of wireless communication, a safety processor and a train positioning technology.
The ATS subsystem, the ground subsystem, the vehicle-mounted subsystem and the data communication subsystem form a CBTC system together. The ATS subsystem of the CBTC is used for realizing train operation adjustment, automatic/manual route setting of the ATS, display, tracking, identification and the like of the train; the ground subsystem is a processor-based system arranged at the control center or beside the track; the vehicle-mounted subsystem comprises a speed measuring and positioning sensor and an intelligent controller; the data communication subsystems arranged at the center, beside the track and on the train can realize data communication with the train, the ground and the interior of the vehicle-mounted equipment. The CBTC has the following basic functions: the system comprises a positioning function, a calculating function, a vehicle-ground two-way communication function, a blocking forming function, a remote diagnosis and monitoring function, a function of providing line parameters and an operation state and the like.
The vehicle-mounted subsystem is an important component of the CBTC system, and when the vehicle-mounted subsystem breaks down, the train is decelerated, delayed and even stopped, and huge economic loss and social influence are caused as a result. At present, the maintenance of a vehicle-mounted system is still very lagged behind, and the main maintenance means comprise auxiliary analysis of a signal monitoring system, vehicle-mounted ATP alarm active maintenance, skylight point maintenance and repair, checking of system logs such as ATP and DMS and the like.
The existing subway operation and maintenance system mainly comprises a signal centralized monitoring system (CSM) and a maintenance monitoring system (MSS).

CSM has monitoring, warning, information storage, state reappearance and other functions, and is convenient for analysts to monitor and diagnose the working state of the field equipment and guide the field maintenance work. The MSS system is based on CSM system, and adds interfaces of ZC, vehicle carried and so on to monitor. As shown in fig. 1, the MSS system detection procedure is as follows:
