System and method for rail train collision prevention based on wireless sensor network

Abstract

The invention relates to a system and a method for rail train collision prevention based on a wireless sensor network. The system is provided with a train head device, a train tail device and a rail side device, wherein the rail side device comprises a wireless sensor network, the wireless sensor network consists of communication base stations and network nodes, a rail line is divided into a plurality of equidistant closing areas, the middle point position in each closing area is provided with one communication base station, both sides of each communication base station are respectively provided with the network nodes in equidistant way, each communication base station is provided with a wireless communication module, GSM-R (global system of for mobile communications for railway) wireless equipment, a power supply module and a rail detector, each network node comprises a wireless communication module, a power supply module and a rail detector, the train head device comprises a main controller, a wireless communication module, a power supply module and a braking module, the train tail device comprises a wireless communication module and a power supply module, the output of the power supply module is connected with the wireless communication module, and the train head device and the train tail device are used as movable nodes and are added into the wireless sensor network of the rail side device.

Description

technical field [0001] The invention relates to anti-collision and rear-end collision accidents during rail train operation, in particular to a rail train anti-collision system and method based on a wireless sensor network, belonging to the technical field of network transmission and automatic control. Background technique [0002] With the continuous expansion of national production and living needs, the transportation industry is also developing rapidly, among which the development of rail transportation is particularly rapid, such as railway passenger and freight, subway, light rail, etc. Once a failure occurs in the rail transit system, it will inevitably cause huge damage, especially when a manned rail vehicle collides or rear-ends, the material loss and mental trauma caused will be irreparable. There are many reasons for rail vehicle collisions or rear-end collisions, which can be roughly divided into two categories: one is human factors, and the other is environmental...
