Embodiment 1

[0071] The embodiment of the present invention provides a vehicle-road coordination-based deceleration and yield sign control crossing early warning system and method. The collision risk is determined through the vehicle-road coordination technology, and a voice warning signal is sent to the motor vehicle to reduce the occurrence of collision accidents between trains and motor vehicles. , Improve the safety of level crossings.

[0072] An aspect of the embodiments of the present invention provides a vehicle-road coordination-based deceleration and yield sign control crossing warning system.

[0073] The principle diagram of a deceleration and yield sign control crossing warning system based on vehicle-road coordination provided by the embodiment of the present invention is as follows figure 1 As shown, the system includes: road vehicle on-board controller 1, central controller 2 and train on-board controller 3, the specific content of each part of the system is as follows:

Embodiment 2

[0129] This embodiment provides an early warning method for crossing control based on vehicle-road coordinated deceleration and yielding signs.

[0130] The method of the embodiment of the present invention is based on the specific process of two-stage pre-warning of the deceleration and yield sign control level crossing based on the system similar to the foregoing embodiments.

[0131] The system includes: a road vehicle on-board controller, which is used to obtain relevant information such as the position coordinates and speed of the vehicle in real time, and send it to the central controller, and at the same time receive the information transmitted by the central controller, and provide voice warning to the driver; The train on-board controller is used to obtain relevant information such as the position coordinates and speed of the train in real time and send it to the central controller; the central controller is used to receive relevant information sent by the road vehicle...

Abstract

The embodiment of the invention provides a speed reducing and way giving marker control crossing early warning system and method based on vehicle infrastructure cooperation. The system comprises a road vehicle vehicle-mounted controller, a central controller and a train vehicle-mounted controller. The road vehicle vehicle-mounted controller acquires road vehicle information in real time and sendsto the central controller, receives early warning executive information transmitted by the central controller and triggers a voice early warning module as well as performs corresponding voice early warning; the train vehicle-mounted controller acquires train information in real time and sends to the central controller; and the central controller receives the road vehicle information and the traininformation and obtains early warning parameters as well as judges whether the early warning executive information is sent to the road vehicle vehicle-mounted controller according to the early warningparameters. The system provided by the embodiment of the invention publishes early warning information of a first stage by calculating an early warning position in real time, judges whether early warning information of a second stage is sent according to a position where a train is located and a speed of the train and reduces a collision risk of the train with a motor vehicle by virtue of a voiceprompt, so that security of a grade crossing is improved.

Description

technical field [0001] The invention relates to the technical field of traffic management, in particular to an early warning system and method for controlling crossings with deceleration and yielding signs based on vehicle-road coordination. Background technique [0002] As a place where railways and roads intersect each other on the same plane, level crossings have always been an accident-prone link in the safety production of railway transportation, and are also dangerous sections of road transportation, directly threatening the personal safety of traffic participants. Because the average ratio of trains and motor vehicles is about 4000 to 1, the collision of motor vehicles and trains becomes the most dangerous traffic accident at level crossings. [0003] For crossings controlled by deceleration and yielding signs, the driver needs to actively search for the train. If the train has not arrived or is approaching the crossing, the driver is not required to take a parking st...
