Abstract

The invention provides a train track section locking time calculation method based on quasi-moving block. The method comprises the following steps of establishing a traction calculation model of a train by analyzing characteristic parameters of a quasi-moving block mode of a high-speed railway; analyzing and calculating the force applied to the train in the running process according to the traction calculation model of the train to obtain the speed-distance curve of the train in the running process: respectively establishing and solving calculation models of the train based on the track section locking time of a section and a station under the quasi-moving block mode according to the speed-distance curve of the train in the running process to obtain the track section locking time of the train based on the section and the station. The train track section locking time calculation method based on quasi-moving block can be used for drawing a train working diagram with Blocking time based on the track section locking time which is finely calculated, provides a basis for the fine use of the train receiving and dispatching routes, realizes the fine expression of the train on the occupation of the transport capacity resources, and meets the requirement of the fine management of a railway system.

Description

technical field [0001] The invention relates to the technical field of train operation, in particular to a method for calculating the locking time of a track section of a train based on a quasi-moving block. Background technique [0002] In recent years, with the continuous upgrading of railway technology, a safer and more intelligent train control system has been pursued. Today, my country's high-speed rail operates trains of different speeds with a speed of 200-350 kilometers per hour. The CTCS-2 and CTCS-3 high-speed train operation control systems of CRSC are used respectively, which are the "brain and central nervous system" of high-speed rail operation. The blocking methods adopted by the CTCS-2 and CTCS-3 high-speed train operation control systems are quasi-moving blocking. Quasi-moving block is a signal system that can not only ensure driving safety, but also improve transportation efficiency. The minimum tracking interval time is the only parameter to calculate th...
