Description

TECHNICAL FIELD

The present disclosure relates to the field of automatic control technology, especially to a station transport dispatching method and system.

BACKGROUND

Chinese high-speed railway signal system mainly includes subsystems like Chinese Train Control System (CTCS), Computer Based Interlocking system (CBI), Central Traffic Control (CTC), as well as some signal auxiliary systems, such as Centralized Signaling Monitoring (CSM), dispatching command wireless transmission system, power supply system, etc.
The train dispatchers are required to use the CTC system to carry out jobs like the formulation and delivery of train movement plan, the train route setting, the shunting operation, the release of dispatching command, the centralized control of signaling equipment, the equipment maintenance dispatching, the emergency traffic commanding, the arrival and departure operation during abnormality, etc. In addition, the dispatchers need to monitor the situation of train operation and signaling equipment such as train tracking, train position and speed, signal status, train route, and section block and so on through the screen wall and display of the CTC system.
The CTC system is technical equipment with which the dispatching center (dispatcher) centrally controls the signaling equipment in a certain section and directly directs, manages the train operation. The CTC system is a highly automated dispatching and commanding system combined with computer technology, network communication technology and modernization controlling technology, which applies the design principle of intelligent decentralized self-discipline. It centers on the train operation adjustment plan control and takes the train operation and shunting operation into account.
The CTC system consists of three parts: the dispatch center subsystem, the station subsystem, and the network subsystem among stations, as shown in FIG. 1.
The dispatch center subsystem is the core of the CTC system, and is mainly composed of server equipment and the terminal equipment in each dispatch station. The server equipment includes: a database server, an application server, a communication server, an interface server, an external information service server, and an external time server. The dispatch station user terminal equipment includes: a dispatcher workstation, an assistant dispatcher workstation, a comprehensive maintenance workstation, a station display workstation, a comprehensive query workstation, a shift supervisor workstation, a planner workstation, a dispatch maintenance workstation, and the like.
The station autonomous machine is the key equipment of the CTC system and should meet the following functional requirements: it should be able to receive the train operation adjustment plan, direct operation commands from the dispatch center and direct operation commands from the station operator, and send them to the station interlocking system at the appropriate time to be executed after inspection with no conflicts; it should be able to receive the station signaling equipment status information in real time, track the train number, collect the actual train running data, and upload it to the dispatch center; it should be able to get the status of execution of the route commands by the station interlocking system, and make necessary adjustments to the relevant routes according to feedback information; it should be able to receive train time report and equipment status information from every two adjacent stations.
UK patent application GB2 511 906 A discloses a railway route control device.
