Embodiment Construction

[0041] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0042] figure 1 The train control vehicle-mounted equipment according to an embodiment of the present application is shown. Such as figure 1 As shown, the train control vehicle-mounted equipment of this embodiment includes a track circuit signal reading unit 10, a line information reading unit 20, and a calculation unit 30. The track circuit signal reading unit 10 reads the track circuit signal, and uses the combination of time and frequency domain to demodulate the track circuit signal based on 2 out of 2 to obtain the train permit information; the line information reading unit 20, from the ground point Read the line information in the transponder; the calculation unit 30 uses the driving permission information and the line information to calculate the speed protection curve of the train.

[0043] Through the foregoing implementation manners, an ATP on-...

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

[0001] This application is a divisional application of the invention application with the application number 201110126531.1 filed on May 16, 2011. Technical field [0002] The invention relates to a vehicle-mounted equipment, in particular to a train control system vehicle-mounted equipment and a method for demodulating track circuit signals. Background technique [0003] Due to the continuous increase in train speed, ground signals and traditional LKJ on-board equipment can no longer protect the train's high-speed and safe operation. Therefore, it is necessary to develop an ATP (Train Overspeed Protection) on-board equipment that meets the technical specifications of the CTCS-2 train control system and can control train operation in real time. Summary of the invention [0004] In order to solve the problems in the prior art, according to an embodiment of the present application, a train control system vehicle-mounted device is disclosed, including: [0005] The track circuit signal...
