Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of train operation control, and in particular to an operation control system, method, device and medium for a CBTC train running on a CTCS line. Background Art

[0002] The construction of metropolitan areas requires the realization of the "four-network integration" of high-speed rail, intercity, urban and urban rail transit, and the realization of integrated urban rail transit construction. At present, there are two technical systems for rail transit train control technology: CTCS and CBTC. Among them, high-speed rail and intercity railway use CTCS train control system, and urban rail mainly uses CBTC signal system. Urban rail, as the link connecting the "four-network integration" of urban and intercity transportation and rail transit, needs to realize the interconnection and cross-line operation between different train control modes.

[0003] The current mainstream technical direction adopts the method of setting up two sets of signal equipment, including using two sets on board (one set of CBTC on-board equipment and one set of CTCS on-board equipment) and arranging CTCS ground and CBTC ground equipment at key ground stations. The system structure is complex and the operation and maintenance are complex. For trains that do not have two sets of on-board equipment installed, it is impossible to achieve interconnection and cross-line operation, which affects the efficiency of train use; for trains with two sets of on-board equipment, the cost is high, and the driver needs to master two sets of operating methods, which is difficult. At present, the key demand of the "four-network integration" of urban rail is that urban rail CBTC trains cross the line to the urban rail line. Because the ground system of the urban rail line cannot support the cross-line operation of CTCS on-board equipment, CBTC trains cannot cross the line to the CTCS line. Summary of the invention

[0004] The embodiments of the present invention provide an operation control system, method, device and medium for a CBTC train running on a CTCS line, which solves the problem that trains without dual sets of on-board equipment cannot achieve interoperability and cross-line operation, affecting the utilization efficiency of the trains; for trains with dual sets of on-board equipment, the cost is high and the driver needs to master two sets of operating methods, which is difficult.

[0007] The train safety control center equipment is respectively connected to the train control ground equipment and the on-board equipment for communication;

[0008] The on-board equipment train is used to send the train operation status information and the door-platform door linkage control instructions to the train control ground equipment through the train safety control center equipment;

[0009] The train control ground equipment is used to send the operation plan information and temporary speed limit information to the on-board equipment through the train safety control center equipment;

[0010] The train safety control center equipment receives the train occupancy and route information of the train control ground equipment and the location information of the on-board equipment, and calculates the movement authorization based on the train occupancy and route information and sends the movement authorization to the on-board equipment.

[0011] Preferably, the train control ground equipment includes: a centralized dispatching system, a temporary speed limit server and an interlocking; the centralized dispatching system, the temporary speed limit server and the interlocking are respectively communicatively connected to the train safety control center.

[0012] The centralized scheduling system is used to receive the operation status information and send the operation plan information.

[0013] Preferably, the temporary speed limit server is used to receive the door-platform door linkage control instruction and send the temporary speed limit information.

[0014] Preferably, the interlocking is used to send the train occupancy and route information to the train safety control center equipment.

[0015] Preferably, the train safety control center equipment communicates with the train control ground equipment and the on-board equipment through LTE and 5G mobile communication channels respectively.

[0016] Preferably, when the CBTC train runs from the CTCS line and the CBTC line or from the CBTC line and the CTCS line, the movement authorization and the operation status information are transmitted between the train safety control center equipment and the CBTC line area controller at the nearby station.

[0017] In a second aspect, an embodiment of the present invention provides an operation control method of a CBTC train running on a CTCS line, an operation control system, method, device and medium of a CBTC train running on a CTCS line, wherein the method is executed by an operation control system of a CBTC train running on a CTCS line, and includes:

[0019] Calculating movement authorization based on the train occupancy and route information;

[0020] The CBTC train operation is controlled according to the movement authorization, the operation plan information and the temporary speed limit information.

[0021] In a third aspect, an embodiment of the present invention provides an electronic device, an operation control system, method, device and medium for a CBTC train running on a CTCS line, wherein the electronic device includes:

[0022] at least one processor; and

The advantage of adopting the ground compatible solution is that when only some stations are running on the same line, less ground equipment can be modified, the investment is small, and the cross-line non-sensing operation of CBTC trains can be supported. In particular, the modification difficulty for some stations on the same line is small and the on-board equipment does not need to be modified. BRIEF DESCRIPTION OF THE DRAWINGS
