Vehicle precision positioning system and method for rail transportation

Abstract

The invention discloses a vehicle precision positioning system and method for rail transportation. The vehicle precision positioning system comprises a two-way trailer mechanism, a two-way car arrester and an intelligent visual detection system. The two-way trailer mechanism is used for enabling the vehicle to move on the rail in the first direction or the second direction until the vehicle reaches the position where the two-way car arrester is located; the two-way car arrester is used for locking the car and can move along the rail together with the car until the car reaches an ideal position; and the intelligent visual detection system is at least used for detecting the actual position of the vehicle on the rail in real time, comparing the actual position of the vehicle on the rail withthe ideal position, and controlling the two-way car arrester to transport the vehicle to the ideal position. The vehicle precise positioning system for rail transportation is suitable for precise positioning in the rail vehicle dispatching and operation process, and the precision can reach + / - 0.5 mm.

Description

technical field [0001] The invention belongs to the technical field of rail transportation, and in particular relates to a vehicle precision positioning system and method for rail transportation. Background technique [0002] In order to adapt to the automatic operation of rail vehicles, the precise positioning of vehicles is a key technical problem that must be solved. All vehicles, including mine cars in coal mines and railway transportation, have the need for precise positioning. For example, in the mining industry, mining vehicles are usually used as transportation tools to transport materials and ores. Mining vehicles often need to be parked at fixed points on the track. The car is towed to the position where the car arrester is located. [0003] However, the trailers currently used to tow mine carts can only do one-way dragging during the trailer process, and cannot meet the requirements of two-way dragging; in addition, in order to adapt to the frequent and changeab...

Problems solved by technology

[0003] However, the trailers currently used to tow mine cars can only do one-way dragging during the trailer process, and cannot meet the requirements of two-way dragging; in addition, in order to adapt to the frequent and changeable mine car transportation process, a Two-way car stoppers can meet the needs of two-way positioning of vehicles under special circumstances. The two-way car stoppers currently developed can only provide vehicle positioning functions, but high-precision positioning (for example: ±0.5mm) cannot be achieved

For some precise operations, it cannot be completed
