Method based on CTC (centralized traffic control) station yard graph graphic elements and used for setting temporary speed restriction of high-speed railway

Abstract

The invention relates to a method based on CTC (centralized traffic control) station yard graph graphic elements and used for setting temporary speed restriction of a high-speed railway. The method comprises steps as follows: 1), a starting point and an ending point of temporary speed restriction are selected according to selection of graphic elements of a block section of a station yard graph; 2), a CTC system receives an input speed limit value and sends a speed limit storage command to a train control system; 3), the condition that the speed limit state is stored is fed back to the CTC system by the train control system; 4), the condition that the speed limit state is stored is displayed on the station yard graph by the CTC system; 5), the CTC system issues a speed limit checking command to the train control system; 6), the condition that the speed limit state is checked is fed back to the CTC system by the train control system; 7), the condition that the speed limit state is checked is displayed on the station yard graph by the CTC system; 8), the CTC system issues a speed limit executing command to the train control system; 9), the condition that the speed limit state is executed is fed back to the CTC system by the train control system; 10), the condition that the speed limit state is executed is displayed on the station yard graph by the CTC system. Compared with the prior art, the method has the advantages of visual and concise operation, high system security and the like.

Description

technical field [0001] The invention relates to a method for setting and supervising a temporary speed limit of a high-speed railway, in particular to a method for setting a temporary speed limit of a high-speed railway based on graphic elements of a CTC station map. Background technique [0002] The speed control of high-speed railway trains adopts CTCS-2 or CTCS-3 train control system, in which different train types need to carry out fixed speed limit under the fixed conditions such as different line curve radius and slope; at the same time, in construction, equipment failure, bad Temporary speed limits are required due to weather conditions, etc. For fixed speed limit, the passive transponder installed on the line stores relevant speed limit data and transmits it to the train when the train passes; for temporary speed limit, the dispatcher enters the speed limit parameter through the CTC system and transmits it to the temporary speed limit server , the temporary speed li...

AI Technical Summary

Problems solved by technology

The main problems of this method at present are: (1) The dispatcher’s input method is not intuitive, and the speed limit line and range need to be confirmed against the station map, and then input in the dialog box; (2) The speed limit range is input by the dispatcher Any range, the train control system needs to dynamically generate speed limit messages, which cannot be exhaustively tested; (3) The speed limit status fed back by the train control system only includes the speed limit range, which is matched to the station map by the CTC system through logical operations For display, the implementation logic is relatively complicated. When there is a difference between the CTC data and the train control data, it may lead to wrong display and mislead the dispatcher, and there is a security risk
