Train tracking interval real-time early warning system based on CTC (central traffic control) and early warning method

Abstract

The invention discloses a train tracking interval real-time early warning system based on CTC (central traffic control) and an early warning method, which belong to the field of high-speed train safety control technology. A dispatching center subsystem early warning server of the system consists of an early warning server and a dispatching command output unit, an application server of the dispatching center subsystem consists of a train number tracking unit and a wireless checking unit, vehicular equipment comprises a wireless train number vehicular encoder, and the system comprises a wireless train number decoder. The method includes acquiring a train number from decoded train comprehensive information by the aid of the wireless checking unit, comparing the acquired train number with a train number obtained by the train number tracking unit, and acquiring an accurate and reliable train number; and computing tracking intervals of a train by the aid of the early warning server, and controlling the dispatching command output unit to output control instruction according to a computation result. The train tracking interval real-time early warning system based on CTC and the early warning method form double channels with an ATP (automatic train protection) computation tracking interval method, a monitoring effect for a train tracking interval ATP control effect is realized, and integral safety of a train control system is improved.

Description

technical field [0001] The invention belongs to the technical field of high-speed train safety control, and in particular relates to a real-time early warning system and early warning method for train tracking intervals based on CTC. Background technique [0002] Rear-end collisions and signal accidents occur frequently, both in China and abroad. Moreover, such accidents account for a relatively high proportion of all railway accidents. [0003] Train rear-end collisions and rushing signal accidents in China include: [0004] On July 23, 2011, the EMU train D301 from Beijing South to Fuzhou was running between Yongjia and Wenzhou South on the Yongwen Line, and had a rear-end collision with the EMU train D3115 from Hangzhou to Fuzhou South. The accident killed 72 people and injured more than 210 people. [0005] On July 31, 2005, the passenger train K127 bound for Changchun from Xi'an collided with the forward freight train No. 33219, causing 5 passenger cars to derail, 6 ...

Problems solved by technology

[0018] (3) There are limitations in the completion of train operation monitoring by train dispatchers

With the development of my country's high-speed rail, the number of high-speed trains continues to increase (there are 72 pairs of trains on the Beijing-Shanghai line); the train speed is fast and there are many signal equipment; the display content of the display screen needs to be switched to browse; Due to visual fatigue and other reasons, it is unrealistic for people to complete the supervision of train operation
