Embodiment 1

[0013] A train driving assistance system based on train-to-ground video transmission. The auxiliary train protection system includes a fixed long-distance surveillance camera installed on the track, or an existing video surveillance system, a distribution and forwarding server, and a special security camera installed in the train driver's cab. The video display and video communication terminal are characterized in that the camera monitoring video is transmitted to a dedicated distribution and forwarding server; the train cab is equipped with a dedicated video display and video communication terminal, and the video image information is called from the dedicated distribution and forwarding server through a high-speed wireless network , and displayed on the video display. During the driving process, the train calls the monitoring video within a certain distance in the driving direction according to its own position information.

[0014] The monitoring camera, the existing video mo...

Abstract

The invention discloses a train running auxiliary system based on train-ground video transmission. An auxiliary train protection system comprises a fixed long-distance monitoring camera arranged on a track or an existing video monitoring system and a distribution and forwarding server as well as a dedicated video display and a video communication terminal which are arranged on a train cab. The system is characterized in that a camera monitoring video is transmitted to the dedicated distribution and forwarding server; the dedicated video display and the video communication terminal are arranged on the train cab, video image information is called from the dedicated distribution and forwarding server through a high-speed wireless network and is displayed on the video display, and a train can call a monitoring video within a certain distance range in front of a running direction in a running process according to own position information.

Description

technical field [0001] The invention relates to auxiliary protection for trains, in particular to a train driving auxiliary system based on train-to-ground video transmission. Background technique [0002] The unbalanced distribution of transporting floating population and various material resources poses a severe test to my country's railway transportation, and the safe operation of railways is obviously a crucial factor to ensure the reliability of transportation. The China Train Control System (CTCS) is divided into four levels, currently CTCS-2 and CTCS-3 are widely used. CTCS-2 checks the occupancy of the track through the track circuit, and transmits information such as the driving permit issued by the train control center to the train; informs the train line information through the transponder, and transmits information such as the temporary speed limit issued by the train control center. CTCS-3 checks the occupancy of the track through the track circuit; transmits t...
