C3 system temporary speed limit command sending method and device

Abstract

The invention provides a temporary speed-restricting command sending method and device of a C3 system. The method comprises the following steps: a TSRS (temporary speed-restricting server) receives a temporary speed-restricting command issued by a CTC (centralized control); and a TSRS performs automatic splitting according to starting points in speed-restricting areas, final points in the speed-restricting areas and the speed-restricting control range of all TCCs (train control centers) and/or RBCs (radio blocking centers) on railway lines corresponding to the line numbers, and sends corresponding speed-restricting commands to all the relevant TCCs and/or RBCs, C2 speed-restricting information is transmitted to C2 vehicle-mounted devices by the TCCs through an active transponder, and C3 speed-restricting information is transmitted by the RBCs through a GSM-R (global system for mobile communications for railway). According to the invention, the TSRS is arranged in a railway system, andacquires the temporary speed-restricting commands by virtue of being connected with the CTC, the temporary speed-restricting commands are distributed to the relevant TCCs and RBCs to realize automatic distribution of all the TCCs and RBCs in the whole-line control range and the centralized management of the train control speed-restricting commands; and the C2 and C3 speed-restricting commands canbe set and canceled simultaneously by the TSRS so as to contribute to guaranteeing the consistency of the two train control systems.

Description

technical field [0001] The invention relates to railway vehicle speed limit technology, in particular to a method and device for sending a temporary speed limit command of a C3 system. Background technique [0002] Temporary speed limit schemes for existing railway vehicles mainly include the following two types, one of which is to print out a text format by the dispatcher on a line running at a speed lower than 160km / h, and call the driver to control the train according to the text speed limit dispatch command run. The other is that on the 200km / h line equipped with CTCS-2 train control equipment, the on-duty personnel at each station respectively issue speed limit commands to the local train control center (TCC) equipment for execution, and then the TCC selects the speed limit for timely scenarios. The speed message is sent to the active transponder to obtain the speed limit data when the C2 EMU passes. [0003] Option 1 uses manual speed limit management, which is prone...

However, if the above-mentioned decentralized control of the prior art is still adopted, the identity of the C3 speed limit and the C2 speed limit cannot be guaranteed.
