Embodiment Construction

[0030] like figure 1As shown, the head unit includes a main controller, a wireless communication module, a power module and a braking module. The rear device includes a wireless communication module and a power module. The trackside devices include communication base stations and network nodes. The communication base stations include wireless communication modules, GSM-R wireless equipment, power supply modules and track detectors. The network nodes include wireless communication modules, power supply modules and track detectors. The track route is divided into several block sections according to a certain track distance, and the trackside devices are arranged in an orderly manner along the track route with equal track distances; the trackside devices in the block sections form a wireless sensor network. The wireless communication modules of the head unit and the rear unit are added to the wireless sensor network as mobile nodes. Design the trackside device located in the ce...

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...
