Abstract

The invention relates to an offset-calculation-based rail vehicle positioning device, system and method. The offset-calculation-based rail vehicle positioning device includes a first data interface, asecond data interface, an accumulator and a third data interface, wherein the first data interface is used for receiving the speed information of a vehicle collected in a current time period, the second data interface is used for receiving a trigger signal given by a reader, the accumulator is used for calculating the offset of the current time period based on the received speed information, andwhen the trigger signal is not received, the offset of the current time period is accumulated on the accumulated offset before, and when the trigger signal is received, the accumulated offset before is subjected to zero clearing, and the offset is restarted to accumulate on the basis of the offset of the current time period; and the third data interface is used for outputting the accumulated offset from the accumulator to the current time period. According to the offset-calculation-based rail vehicle positioning device, system and method, a mode of calculating the offset is adopted to determine the current position of the vehicle, and the positioning accuracy is higher.

Description

technical field [0001] The invention relates to the technical field of rail vehicle control, in particular to a rail vehicle positioning device, system and method based on offset calculation. Background technique [0002] With the popularity of automobiles, urban traffic is under increasing pressure, and accidents are gradually increasing. Since ground transportation is unaffordable, and underground transportation is expensive and space is limited, air rail transportation has emerged as the times require. [0003] In the development process of track unmanned vehicle driving, various information collection, processing and control are required, especially the higher the real-time and accuracy requirements, the better. For example, the location information of vehicles can be collected through GPS at present, but the real-time and accuracy are difficult to guarantee. Therefore, how to realize precise positioning is an urgent technical problem to be solved at present. Content...
