Detection device, rail train and rail locomotive for detecting motion state of moving object

Abstract

The invention discloses a detection device for detecting motion state of a moving object. The device is characterized by comprising a movable part and a displacement detection device; a relative position of the movable part to the displacement detection device is changed during a curve movement with the moving object; the displacement detection device does not generate an output signal when the relative position of the displacement detection device to the displacement detection device is not changed, while when a relative position of the two is changed, the signal is output; or the displacement detection device generates the output signal when the relative position of the displacement detection device to the displacement detection device is changed, while when a relative position of the two is changed, no signal is not output. The device of the invention is especially suitable for detecting whether a rail train is in a curve movement. The moving amplitude during the curve movement is amplified, so as to better facilitate the detection, lower precision requirement on the displacement detection apparatus and production costs, and realize easier detection and better detection effect. Besides, the invention has simple structure and is easy for manufacture and convenient for usage.

Description

technical field [0001] The invention relates to a detection device for detecting the motion state of a moving object, a rail train and a rail locomotive. Background technique [0002] The track of the railway consists of two rows of steel rails arranged in parallel. Each train locomotive or car bottom is equipped with multiple pairs of wheelsets. Each wheel set includes at least two wheels, and each wheel is supported on a row of steel rails. Existing railway lines often span thousands of kilometers or even tens of thousands of kilometers. Because the terrain of the railway crossing range changes greatly, the trajectory of the railway must be adjusted accordingly. In some areas, the railway is a straight line; in some areas, the railway is set in a curve. In China, the track changes of railways are more diverse. The shape of the railway track is various, which determines that the running track of the train includes both a straight track and a curved track. In most part...

AI Technical Summary

Problems solved by technology

Although this can solve the problem of how to judge whether the train car is moving in a straight line or a curve to a certain extent, the implementation is very complicated

One is that because the railway line is long, it is a very large project to collect and record all the tracks of all the railways, and the continuous updating of the railways will also change the shape of the tracks. If the records are not updated in time, it will lead to wrong judgments ; Second, there are many management departments involved in the difficulty of on-site maintenance of equipment
