Post-station unmanned automatic turn-back method suitable for urban railways

Abstract

The invention relates to a post-station unmanned automatic turn-back method suitable for urban railways, which comprises the following steps of: adding a through communication line to realize communication between vehicle-mounted equipment at two ends of a motor train unit, automatically entering a turn-back pull-out line of a train to stop stably, and automatically changing ends and activating toenter a working state through a data through line, so that the turn-back end changing time of the train is greatly shortened; and the utilization rate of the turn-back line is improved, so that the operation requirement that the public transportation operation turn-back time of urban railways is shorter than 3 minutes is met. Compared with the prior art, the method has the advantages that the endchanging time of the vehicle-mounted equipment on the turn-back line is greatly shortened, and the potential safety hazard that an existing national railway turn-back station yard with the cross-linefunction mistakenly drives an unmanned turn-back train into a non-turn-back line to enter other lines after standing is avoided.

Description

technical field [0001] The invention relates to a signal control system for urban railways, in particular to an unmanned automatic return method for urban railways. Background technique [0002] At present, the development of my country's urban railways 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 commuting, rapid Large-capacity rail transit system. [0003] It can be seen from this that the main functional orientation of the urban railway is to provide urban public transport services to alleviate urban traffic congestion; to provide commuter traffic within the city area to promote the construction of new urbanization; to provide commuter traffic across cit...

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.
