Abstract

A train position checking and interval early warning system based on train instrument image analysis. The present invention arranges the high-speed camera on the train so that it can capture the DMI display screen of the train in real time, and then, the present invention preprocesses the captured image data and transmits it to the traffic command center in real time through satellite communication, and the traffic command center passes the image The algorithm analyzes and extracts the train running status information in real time, and then calculates the interval between trains based on the train position and train speed information. When the train speeds up or exceeds the safe distance or the data is abnormal, it will output the warning result of the safe distance or directly remind the driver.

Description

technical field [0001] The invention relates to the technical field of train operation control, in particular to a train position check and interval early warning system based on train instrument image analysis. Background technique [0002] my country's existing China Train Operation Control System (CTCS) is used as a monitoring device to ensure the safe operation of trains. It is currently divided into five levels (CTCS-0, CTCS-1, CTCS-2, CTCS-3, CTCS-4 levels) . During the operation of the train, the realization of the train control function depends on the accurate acquisition of information such as the position and speed of the train. At present, my country's high-speed railway train operation control system generally uses ground transponders to assist wheel sensors to obtain train position information status. In the prior art, the train occupancy check is realized by utilizing the circuit elements laid on the train track to sense or interact with the train. [0003] I...
