Abstract

The invention discloses train control system on-board equipment, which comprises a track circuit signal reading unit, a line information reading unit and a calculation unit, wherein the track circuit signal reading unit is used for reading a track circuit signal and demodulating the track circuit signal based on two-out-of-two demodulation in a time frequency domain combined mode to acquire train running license information; the line information reading unit is used for reading line information from a ground point type responder; and the calculation unit is used for calculating a speed protection curve of a train by using the training running license information and the line information. The invention also discloses a method for demodulating a track circuit signal. The invention provides ATP (Automatic Train Protection) on-board equipment which meets CTCS-2 level train control system technical specification and can control the train operation in real time.

Description

technical field [0001] The invention relates to a vehicle-mounted device, in particular to a train control system vehicle-mounted device and a method for demodulating track circuit signals. Background technique [0002] As the speed of the train continues to increase, it is no longer possible to protect the high-speed and safe operation of the train by relying on ground signals and traditional LKJ on-board equipment. Therefore, it is necessary to develop an ATP (Train Overspeed Protection) on-board equipment that complies with the CTCS-2 train control system technical specification and can control the train operation in real time. Contents of the invention [0003] In order to solve the problems in the prior art, according to an embodiment of the present application, a vehicle-mounted equipment of a train control system is disclosed, including: [0004] The track circuit signal reading unit reads the track circuit signal, and demodulates the track circuit signal based on ...
