An unmanned automatic return method after station suitable for municipal railways

Abstract

The invention relates to an automatic return method for unmanned people behind the station suitable for urban railways. The method enables the on-board equipment at both ends of the EMU to realize communication by adding a through communication line. Switching ends is activated and enters the working state, which greatly shortens the time for the train to turn back and changes the terminals, and improves the utilization rate of the return line, thus realizing the operational requirement that the return time of the bus-oriented operation of the urban railway is less than 3 minutes. Compared with the prior art, the present invention has the advantages of greatly shortening the time for on-board equipment to change ends of the turnaround line, and solves the problem that unmanned turnaround trains mistakenly enter a non-turnback line and enter other turns after the existing national railway has a cross-line function at a turnaround station. Line safety hazards and other advantages.

Description

technical field [0001] The invention relates to a signal control system of a municipal railway, in particular to an unmanned automatic return method after a station suitable for the urban railway. Background technique [0002] At present, the development of urban railways in my country is lagging behind, and the effective supply capacity is insufficient, which has become a shortcoming in the development of urban public transportation. The National Development and Reform Commission's "Guiding Opinions on Promoting the Development of Urban (Suburban) Railways" (Document No. 1173) gives the definition of urban railways: Urban (suburban) railways are the commuting and fast commuting between urban central urban areas connecting surrounding town groups and their urban groups. A large-capacity rail transit system. [0003] From this, it can be seen that the main functions of urban railways are to provide urban public transportation services to alleviate urban traffic congestion; t...

Problems solved by technology

[0005] The mainstream signaling system adopted by urban rail transit in China is the CBTC system. The automation level has been applied to GoA3 and GoA4 levels. The upper limit is lower than 120km / h, which cannot meet the commuting needs of urban railways between cities. More importantly, the CBTC system cannot achieve cross-line operation with national trunk railways and intercity railways, and cannot meet the needs of interconnection and intercommunication.

[0006] Therefore, how to upgrade the reentry function on the basis of CTCS2+ATO system to break the long reentry interval has become a technical problem that needs to be solved at present.
