Abstract

The invention provides a railway level-crossing active safety prewarning system and method. When a train is driven in a level-crossing prewarning estimating range, mobile terminals of train or road users and road terminals form ad hoc networks for wireless communication through mutual distribution and reception of data; the mobile terminals of the road users receive position data in the train mobile terminals and level-crossing data in the road terminals; the collision probability is calculated by using a collision probability estimating model through actual position probability density functions of the road users and fence wood machine control state probability density functions; and when the collision probability is higher than a threshold, mobile terminal alarm modules of the road usersare activated for prewarning and displaying of the waiting time. The railway level-crossing active safety prewarning system and method can realize real-time prewarning and active defence.

Description

technical field [0001] The present disclosure relates to an active safety warning system and method for railway level crossings. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Railway level crossing is the level intersection of highway and railway, and is a common part of highway and railway. There are many uncontrollable factors in its safety management, and the consequences of accidents are serious. It is the key to the control of railway off-road accidents, and it is necessary to strengthen prevention and eliminate hidden dangers. [0004] Accidents at railway level crossings can be divided into active accidents and passive accidents. Active accidents are caused by illegal operations or actions of train drivers or other road users (vehicles or pedestrians, etc.). Most of them are difficult to predict and prevent. Correspondingly, r...
