Rail vehicle ground positioning speed-measuring system

Abstract

The invention discloses a ground positioning velocity-measuring system for a railbound vehicle, comprising a tooth space plate arranged on the railbound vehicle, a plurality of zoning detectors arranged on the railbound vehicle, an upper processer and at least one middle processer arranged between the zoning detectors and the upper processer, wherein, the middle processer is connected with the plurality of zoning detectors and the upper processer and is used for grouping the plurality of zoning detectors and realizing the module management; the assembling spaces among the plurality of zoning detectors are arranged at will, at least two zoning detectors detect the tooth space plate simultaneously, thereby guaranteeing the normal operation of the system under the circumstance that a part of the device is damaged. The information detected by the zoning detectors is transmitted to the middle processer, and the effective information after processed is transmitted to the upper processer for processing the practical number of test points which is the number of vehicles on the line, and the information of each vehicle is outputted. The ground positioning velocity-measuring system can be applied to the ground positioning and speed measurement for the railbound vehicle such as a magnetic suspension train and a subway.

Description

technical field [0001] The invention relates to a method for detecting the position and moving speed of a rail vehicle on the ground. Background technique [0002] Chinese Invention Patent Publication CN1769845A (published on May 10, 2006) discloses a method for detecting the position and velocity of an object moving along a track. This method judges the relative movement of objects based on the principle of baffle-type light-transmitting and light-blocking. When there is relative movement with the partition detector, the partition detector calculates the relative movement of the vehicle according to the detected number of changes in the positioning state, and determines the moving direction of the moving object along the track according to the order in which the positioning state is transferred in the cycle table, and the upper processor The position and velocity of the moving object are calculated by fusing the signals detected by all partitioned detectors. The detection...

AI Technical Summary

Problems solved by technology

[0003] 1) When the line is long, the number of partition detectors is large, and the upper processor must be connected with all the partition detectors, resulting in a large number of interfaces of the upper processor and complicated processing procedures, which makes design, production, debugging and maintenance very difficult. difficulty;

[0004] 2) Only the relative positioning function is realized;

[0005] 3) The failure of any partition detector on the whole line will lead to the paralysis of the whole system;

[0006] 4) Only applicable to the situation where there is only one car on the whole line
