Train movement authorization control method and radio block center

Abstract

The embodiment of the invention discloses a train movement authorization control method and a radio block center. The train movement authorization control method comprises the following steps of: receiving train position reports fed back by a first train and subsequent trains of the first train, wherein the train position report of the first train comprises positional information for the current running of the first train, and the train position reports of the subsequent trains comprise positional information for the current running of the subsequent trains; determining a movement authorization terminal point of the subsequent trains according to the positional information for the current running of the first train and the subsequent trains; and transmitting the movement authorization terminal point to the subsequent trains. In the embodiment of the invention, the movement authorization terminal point of the subsequent trains can be determined according to the positional information for the current running of the trains in the train position reports fed back by the trains, the dependency on interlocking can be reduced, the accident rate can be reduced, and the movement safety can be improved.

Description

technical field [0001] The embodiment of the present invention relates to rail train control technology, in particular to a train driving permission control method and a wireless block center. Background technique [0002] The current Chinese Train Control System 3 (CTCS-3 for short) train control system is based on the Global System For Mobile Communication for Railways (GSM-R for short) wireless communication dedicated to railways, realizing The train operation control system with two-way transmission of train-ground information has the function of Chinese Train Control System 2 (CTCS-2 for short). Among them, the Radio Block Center (RBC for short) in the CTCS-3 train control system generates traffic permits, the track circuit performs train occupancy checks, and the transponder performs train positioning. The driving permit is the driving certificate for the safe operation of the train. A driving permit can include multiple consecutive block zones. The interlocking in ...

Problems solved by technology

Figure 1a is a schematic diagram of an existing normal driving permit, Figure 1b Schematic diagram for existing faulty permits, such as Figure 1a As shown, under normal circumstances, RBC uses the entrance of the occupied route of ATP on the first train 1 as the end point A of the driving permission according to the information of the route occupied by the ATP on the first train 1 fed back by the interlocking system. At this time, it is located at The ATP on the follow-up train 2 after the first train will drive according to the end point of the driving permit, and no rear-end collision accident will occur; if Figure 1b As shown, in some special cases such as: if the track circuit or interlock failure and other reasons, the interlock cannot detect or detects the wrong ATP route occupancy status on the first train 1, therefore, the interlock is sent to RBC The route occupancy information is wrong, and the RBC calculates the wrong end point B of the traffic permit and sends it to the ATP of the follow-up train 2, which may lead to a rear-end collision accident

[0004] To sum up, the existing train control system relies heavily on interlocking during the process of permitting traffic, and the accident rate is high
