The CBTC train is a city train running in public transportation, such as subway and inter-city rail transit, and adopts a CBTC system as a signal system. When a CBTC train needs to run to a line of a C2 system across networks, usually, due to incompatibility of signal systems, the state of each line needs to be checked manually many times to realize route handling, but automatic handling cannot be performed through existing interlocking equipment.

As shown in fig. 1, the train cross-network operation system of the embodiment of the invention mainly comprises CBTC train on-board equipment 110 and CBTC ground equipment 120.

In the prior art, the CBTC train in-vehicle device 110 and the C2 train in-vehicle device have similar structures, but the CBTC train in-vehicle device 110 is not provided with a track circuit reader and a judicial recording unit.

In order to realize compatibility with a C2 system, the CBTC train on-board equipment 110 of the embodiment of the invention is further provided with a C2 system interface module 111 based on the original CBTC train on-board equipment 110. The C2 system interface module 111 is configured to communicate with a C2 ground device, and the C2 system interface module 111 is capable of implementing communication with the C2 ground device on the basis of communication between the CBTC train on-board device 110 and the CBTC ground device 120.

For example, the C2 system interface module 111 may communicate wirelessly with C2 surface equipment via a data communication system DCS.

The ZC is a ground core device of the CBTC system, and the ZC needs to acquire related data information from various devices to operate, and transmit an operation result to an ATP vehicle-mounted subsystem through a wireless communication system, so that the operation safety of all trains in jurisdiction is ensured, and mobile blocking is realized.

To achieve the interlock, the ZC needs to acquire the trackside equipment information and the line operation state information. The trackside equipment information may include signal status, switch position and status, platform door status, axle counter status, and the like. The line operational status information may include zone occupancy information, route information, logical zone lock status information, guard zone status information, emergency stop button status, no-man automatic turn back button status, and the like.

The vehicle-mounted device needs to provide information such as position report, application layer registration/cancellation request and the like for the ZC, and the ZC needs to feed back information such as train control information, application layer registration/cancellation response, application layer cancellation request, special control message (such as temporary speed limit) and the like for the vehicle-mounted device.
