Problems solved by technology

[0011] Using method 1 for RBC switching, two radio stations are required on the vehicle equipment to maintain two wireless channels, the processing process is complicated, and the system cost is increased; in addition, it takes a long time to re-establish a new wireless channel
When using method 2 for RBC switching, the on-board equipment needs to disconnect from the original RBC and re-establish a connection with the new RBC, which causes the interruption of communication between the on-board equipment and the ground, making it impossible for the ground control equipment to obtain the information of the train. In the running state, the control command cannot be issued, and there are potential safety hazards

Embodiment 1

[0041] This embodiment provides a method for control switching of on-vehicle equipment, which is applied to a train control system to control the on-vehicle equipment to perform control switching of a radio block center (RBC). The method can shorten the RBC switching time, reduce the interruption of the connection between the RBC and the vehicle equipment, enhance the reliability of the system, and reduce the cost of the system.

[0042] Such as figure 1 As shown, the method for the control switching of the vehicle-mounted equipment includes:

[0043] 101. It is learned that the vehicle-mounted equipment needs to perform RBC switching.

[0044] Wherein, the knowing that the vehicle-mounted device needs to switch RBC specifically includes:

[0045] The switching device receives the first switching request message sent by the vehicle-mounted device;

[0046] Specifically, before the vehicle-mounted device needs to switch the RBC, a first switch request message sent by the veh...

Embodiment 2

[0064] In this embodiment, the application scenario is CTCS-3, where the first RBC is RBC 1, and the second RBC is RBC 2. Before the vehicle-mounted device needs to perform RBC switching, the vehicle-mounted device sends a switching request message to the ground conversion device; during the switching process, the vehicle-mounted device maintains a dual connection with the RBC.

[0065] Such as figure 2 As shown, the method for the control switching of the vehicle-mounted equipment includes:

[0066] 201. The train runs in the control area of ​​RBC 1, and the on-board equipment communicates with RBC 1 through a wireless channel.

[0067] The on-board equipment sends a position report to RBC 1, and receives the driving authorization from RBC 1 to control the train operation. Among them, the on-vehicle equipment and the ground conversion equipment are connected through a GSM-R wireless channel, and the connection between RBC 1 and the ground conversion equipment is TCP / IP.

Embodiment 3

[0093] In this embodiment, the application scenario is CTCS-3, where the first RBC is RBC 1, and the second RBC is RBC 2. When the vehicle-mounted device needs to perform RBC switching, the vehicle-mounted device sends a switching request message to the ground switching device; during the switching process, the vehicle-mounted device maintains a dual connection with the RBC.

[0094] Such as image 3 As shown, the method for the control switching of the vehicle-mounted equipment includes:

[0095] 301-305, and figure 2 Steps 201-205 in the illustrated embodiment are the same and will not be repeated here.

[0096] 306. After the train passes the RBC switching point, the vehicle-mounted device sends a first switching request message to the ground switching device, and the first switching request message carries an instruction to switch RBC 1 to RBC 2 .

[0097] Wherein, the message format of the first handover request message is the same as that described in step 206 in the...

Abstract

The embodiment of the invention discloses a control switching method for on-vehicle equipment, which is applied to a train control system to control the on-vehicle equipment to perform the control switching between radio block centers (RBC). The control switching method comprises the following steps of: acquiring that the on-vehicle equipment needs to perform the control switching between the RBCs; and establishing connection with a second RBC and disconnecting a first RBC at the same time of maintaining the connection with the on-vehicle equipment to finish the control switching, wherein the first RBC is the RBC currently connected with the on-vehicle equipment; and the second RBC is the RBC which is the target RBC of the control switching performed by the on-vehicle equipment. The embodiment of the invention also discloses ground switching equipment and the train control system. The control switching method, the ground switching equipment and the train control system are applied to the switching of the on-vehicle equipment among a plurality of RBCs in wireless transmission and control.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for controlling switching of vehicle-mounted equipment, ground switching equipment and a system. Background technique [0002] CTCS-3 (Chinese Train Control System 3, three-level train control system) is based on GSM-R (GSM for Railway, railway mobile communication system standard) wireless communication to realize two-way transmission of vehicle-ground information, RBC (Radio Block Centre, wireless block center) train control system that generates traffic permits. The system control part is mainly divided into two parts: vehicle subsystem and ground subsystem. [0003] The on-board subsystem mainly controls the safe operation of the train by receiving the line information and driving permit sent by the ground subsystem. The on-board subsystem includes safety computers, GSM-R radio stations and other equipment, among which, the safety computer is used to calcula...
