Rail transit signal system with multi-network integration

A rail transit signal system with multi-network integration, comprising:

• a wayside train control subsystem for simultaneously supporting tracking operation of a China train control system (CTCS)-based national railway train and a communication based train control (CBTC)-based urban rail transit train, the wayside train control subsystem being configured to control trains having a target speed, a line length, a station spacing, and an operation interval different from each other;
• a compatible carborne subsystem for realizing cross-line operation of a national railway line network, an intercity railway network, a municipal railway network, and an urban rail transit network;
• a networked intelligent dispatching subsystem for realizing intelligent dispatching management of rail transit line networks and cooperation of line network operation plans between different rail transit line networks;
• an interlocking subsystem being respectively communicatively connected to and interacting with the wayside train control subsystem, the compatible carborne subsystem, and the networked intelligent dispatching subsystem;
• and
• a wireless train-ground communication subsystem for providing communication for the national railway train and the urban rail transit train,
• wherein the wayside train control subsystem includes a zone controller, a radio block center, a train control center, a temporary speed restriction server, a track circuit, and a beacon,
• the zone controller being connected to the compatible carborne subsystem, the networked intelligent dispatching subsystem, and the interlocking subsystem,
• the radio block center being connected to the temporary speed restriction server, the compatible carborne subsystem, and the interlocking subsystem,
• the train control center being connected to the track circuit, the beacon, the temporary speed restriction server, the networked intelligent dispatching subsystem, and the interlocking subsystem,
• the temporary speed restriction server, the track circuit, and the beacon being connected to the compatible carborne subsystem, and
• the track circuit being connected to the interlocking subsystem,
• wherein the wayside train control subsystem further includes a wayside switch machine and a signal machine connected to the train control center,
• the train control center being configured to generate a code sequence of the track circuit and a movement authority based on location information of the train and collected equipment status information of the wayside switch machine, the signal machine, and the track circuit, to control operation of trains of different systems and to realize safety interval protection between the trains,
• wherein the networked intelligent dispatching subsystem is configured to manage a fixed number of national railway trains and an unfixed number of urban rail transit trains by labeling train attributes,
• wherein the interlocking subsystem is configured to
• control the switch machine and the signal machine based on a route command,
• collect statuses of a platform door, an emergency stop button, and the track circuit, and
• lock and unlock of a route,
• wherein the interlocking subsystem includes interfaces with the zone controller, the wayside train control subsystem, and the compatible carborne subsystem.
