Transverse displacement detection module for high speed train wheeltracks

Abstract

The invention relates to a warning device for measuring relative positions of high speed train wheeltracks in real time. The warning device comprises a digitized image acquisition module, a wheeltrack relative-position calculation module, a display module, a communication module and a warning module, wherein the digitized image acquisition module comprises a high-speed CCD (Charge Coupled Device) camera, a lens, a light source and a protective cover, the high-speed CCD camera, the lens and the light source are used for completing accurate acquisition of wheeltrack images at the front end, and then the acquired wheeltrack images are transmitted to the wheeltrack relative-position calculation module at the rear end; the wheeltrack relative-position calculation module is connected with the digitized image acquisition module through a serial port and an internet port, and used for controlling the running and stopping of the digitized image acquisition module, receiving the wheeltrack image information acquired by the digitized image acquisition module and completing processing and data calculation on the images; the display module is used for performing visibility processing on the calculated position data and status; the communication module is used for realizing the communication of the device with other equipment on the train; the warning module is used for warning that the relative positions between the wheeltracks exceed an alarm value. The warning device is high in accuracy, capable of realizing real-time measurement, high in speed, good in security, high in stability, and simple and convenient to use.

Description

technical field [0001] The invention relates to a real-time measurement and alarm device for the relative position of the wheel and rail of a high-speed train, which can monitor the relative position between the wheel and rail in real time, and can send an alarm to the train driver through data analysis and judgment, and the train driver can operate the train to decelerate or stop the train in due course , so as to prevent the occurrence of derailment accidents. Background technique [0002] Railway transportation is the main artery of the national economy. In modern wheel-rail railway transportation, accidents of train derailment often occur during operation, and train derailment accidents account for the highest proportion of total railway accidents, which is one of the serious accidents that endanger the safety of railway transportation. In order to effectively prevent the occurrence of train derailment accidents, it is necessary to add a device to monitor the relative p...
