Abstract

The present invention provides a method for calculating the track section locking time of a train based on a quasi-moving block. The method includes: establishing a traction calculation model of the train by analyzing the characteristic parameters of the quasi-moving block mode of the high-speed railway; analyzing and calculating the force received by the train during the running process according to the traction calculation model of the train, and obtaining the speed of the train during the running process ‑Distance curve: According to the speed‑distance curve of the train during operation, the calculation model for the locking time of the track section based on the section and station of the train in the quasi-moving block mode is established and solved, and the track based on the section and station of the train is obtained Section lock time. The method of the present invention can lay out a train operation diagram with Blocking time based on the refined calculation of the track section locking time, provide a basis for the refined use of train receiving and departure paths, and realize the refined expression of the capacity resources occupied by trains , to meet the needs of refined management of the 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...
