Abstract

The invention relates to the technical field of simulation of CTCS-3 training simulation platforms, and discloses a train multi-speed operation experiment method based on a CTCS-3 level train control system. According to the train multi-speed operation experiment method based on the CTCS-3 level train control system, analogue simulation is carried out through a method of setting program operation time and a speed calculation formula, setting a program operation period, calculating system time, setting a difference between comparison time and calculating train displacement. According to the method, the program operation cycle of a speed calculation method and the program operation time of a displacement calculation method are set, the train speed and the forward movement displacement are calculated in advance, and the purpose of high-precision multi-speed operation is achieved; by adopting a method of high-precision double-speed operation from 1 time to 20 times, rapid simulation of running between two stations, long-distance running and running route whole-course running is realized, the running time of a running diagram is shortened, the method is used for verification after a dispatcher adjusts the running diagram, and development, later maintenance and extension in a. NET Core3.1 framework are more convenient.

Description

technical field [0001] The invention relates to the field of simulation technology of a CTCS-3 training simulation platform, in particular to a train double-speed operation experimental method based on a CTCS-3 train control system. Background technique [0002] The professional skills training of front-line railway workers is becoming more and more important. Due to the limitation of on-site vehicle equipment by many factors such as safety, there are few opportunities for students to carry out principle teaching and operation exercises. Most high-speed rail operating companies use high-speed train control simulation training systems for employees. Training. The current high-speed train control simulation training system is designed and developed according to the real railway system operation scenario. The running speed and time of the system train are the same as the real train. When the dispatcher adjusts the operation diagram, he needs to wait for the real train to run th...
