Abstract

A train approach early warning method and system based on train-ground signal fusion, comprising: a TDCS system server sends part of the train running status information to a TDCS conversion server; a handheld terminal sends a protection area to the TDCS conversion server through a wireless network, and the TDCS conversion server receives After the protected area is sent by the handheld terminal, the acquired train running status information is compared with the location information of the protected area to determine whether there is a train entering the protected area; when a train enters the protected area, the TDCS conversion server sends a message through the wireless network. The early warning information is sent to the handheld terminal, and the handheld terminal performs early warning. The invention uses TDCS data and radio data to realize the integration of remote inter-station early warning and real-time approach early warning. The closer the train is to the work site, the more accurate the early warning data is, and it effectively warns the on-site workers to avoid vehicles when they get off the road.

Description

technical field

[0001] The invention belongs to the field of locomotive safety protection, and in particular relates to a train approach early warning system based on train-ground signal fusion. Background technique

[0002] Safety is an eternal theme in the railway industry. In many railway fields such as train service, electricity service, engineering work, power supply, etc., it is inevitable to carry out construction work along the railway line in daily work. Although the railway management department has proposed various rules and regulations, the on-site operators still lack the intuitive experience of the train approaching. Technical means, personal and equipment safety accidents occur from time to time. Railway train approaching early warning technology is mainly applied to the safety protection of personnel and tools on the railway construction site. It continuously monitors the speed and distance of trains approaching the construction section through technical mea...
