Problems solved by technology

Among them, adjacent line interference and traction return interference are more obvious, and adjacent line interference leads to locomotive signal upgrades from time to time
[0005] 2. Train control information is transmitted in one direction and cannot be confirmed in a closed loop
The train control information is transmitted from the ground to the on-board equipment through the track circuit or transponder, and the on-board equipment cannot return the information to the ground
Therefore, the ground cannot determine whether the transmitted signal was received by the locomotive signal, or whether the received signal was correct
[0006] 3. There are many disadvantages in the coding of the track circuit in the station
The track circuit in the station cannot realize closed-loop inspection, and the information transmission is unreliable; the side line connection and departure cannot be coded, resulting in discontinuous locomotive signal display, and no ...

Embodiment Construction

[0030] There is a CTCS2 level train control system under test, which includes adding station train control centers at stations, installing train overspeed protection (ATP) equipment on EMUs, installing electronic units (LEUs), active transponders and Passive transponder and other trackside equipment can realize the provision of information such as temporary speed limit value and train route to the on-board ATP equipment on the ground. And the CTCS2 level train control system based on the wireless locomotive signal of the present invention is a point-connected system in which passive transponders, section track circuits and wireless channels transmit train control information, and its system basic structure is shown in Figure 1. Install on-board ATP equipment and wireless locomotive signal on-board equipment on the EMU, where ATP on-board equipment includes safety computer, man-machine interface (DMI), recorder, brake interface, track circuit information receiving module (STM) a...

Abstract

A CTCS2-class train control system based on wireless locomotive signals is a pint-to-point system for transmitting the train control information via passive responder, regional rail circuit and wireless channel. It is composed of the locomotive carried equipment consisting of ATP device and wireless signaling device, and the ground equipment consisting of wireless signaling device, responder, rail circuit ZPW2000, interface for computer or electric centralizing linkage 6502, and interface for train scheduling and command system or scheduling centralizing system (TDCS or CTC).

Description

Technical field: [0001] The invention relates to a CTCS level 2 train control system, in particular to a CTCS level 2 train control system based on wireless locomotive signals. The invention belongs to the technical field of railway signals. Background technique: [0002] At present, the technical level of my country's railway train operation control can not meet the needs of high-speed and high-density transportation, and the key technologies and integration methods of high-speed passenger train operation control can only rely on imports. In order to meet the needs of train speed increase and operation safety, my country has formulated the "China Train Control System CTCS Development Plan". The development plan refers to the European train control system ETCS and combines the current situation and future development needs of China's train control system, and divides China's train control system into five levels: CTCS0-CTCS4. In the sixth speed increase, the 200Km / h EMU wi...
