Embodiment 1

[0057] A train control system level conversion system, including CTCS-0 ground signal equipment, CTCS-0 vehicle-mounted equipment, CTCS-2 vehicle-mounted device, CTCS-2 train control center, semi-automatic block change direction logic circuit and train control level conversion device, train The control level conversion device includes balise group 1, balise group 2, balise group 3, balise group 4, balise group 5, track circuit, CTCS-2 station inbound signal, CTCS-2 station outbound signal and CTCS-0 station arrival signal. Schematic diagram of the setup of the train control level conversion device as shown in image 3 shown. The interval between CTCS-0 station and CTCS-2 station is divided into CTCS-0 area and CTCS-2 area by the level conversion transponder 3; it is divided into CTCS-0 station, non-track circuit section and CTCS- 2 stops.

[0058] Among them, the level conversion devices within the throat area of ​​CTCS-2 station include transponder group 1, transponder gro...

Abstract

The invention discloses a train control grade transition system and method thereof in the technical field of train control. The method includes the steps that 1, a CTCS-2 station train control centeridentifies the state of a polarized relay in a semi-automatic blocking change direction logic circuit, and the CTCS-2 station pickup and departure states are formed; and 2, during CTCS-2 station departure, a train speed monitoring curve is modified by adding and modifying reverse operation message parameters; during CTCS-2 station lateral pickup, a speed limiting point is set at a grade transitionpoint to modify the train speed monitoring curve, a train passes through the boundary of a CTCS-2 station and a CTCS-0 station according to speed limiting of the train speed monitoring curve, and meanwhile, a train on-board device completes switching of a CTCS-2 system and a CTCS-0 system. The train control grade transition system and method thereof has the beneficial effects that in case of maintaining semi-automatic blocking of the existing two stations, an interval trackless circuit, no additional renovation work of the CTCS-0 station, non-stopping switching of the train between the CTCS-0train control system and the CTCS-2 train control system is achieved, speed transition during switching is stable, and the efficiency of train transportation is improved.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to a train control level switching system and a method thereof. Background technique [0002] CTCS (Chinese Train Control System) is China's train operation control system, which has two subsystems, namely the on-board subsystem and the ground subsystem. The ground subsystem can be composed of the following parts: transponder, track circuit, wireless communication network (GSM-R), train control center (TCC) / radio blocking center (RBC). Among them, GSM-R does not belong to CTCS equipment, but it is an important part. [0003] The transponder is a transmission device that can send message information to the on-board subsystem. It can not only transmit fixed information, but also connect to the trackside unit to transmit variable information. [0004] The track circuit has the functions of track occupancy inspection and continuous transmission of ground vehicle information alon...
