The invention discloses a speed detecting method and a device for a track inspection vehicle, wherein the method comprises the following steps: receiving a distance value between a laser range finderand a railway, and correspondingly matching the distance value with a receiving time; obtaining a speed calculation parameter corresponding to the current time according to the distance value corresponding to the current time; if determining that the speed calculation parameter corresponding to the current time is greater than a preset value, obtaining the distance value corresponding to the preset number of vehicle speed calculation parameter; obtaining a time difference corresponding to the current time according to the speed calculation parameter corresponding to the current time, the distance value corresponding to the preset number of speed calculation parameters, and the receiving time corresponding to each distance value; calculating the speed corresponding to the current time according to a distance between two adjacent sleepers and the time difference corresponding to the current time. The device is for performing the above method. According to the speed detecting method and device for track inspection vehicle, the convenience of detecting the speed of the track inspection vehicle is increased.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a speed detection method and device for a rail inspection vehicle. Background technique [0002] With the rapid development of my country's national economy, railway construction is advancing rapidly, and correspondingly, railway transportation has also achieved unprecedented development. Various scales of rail inspection vehicles are tested. The line array high-speed camera is a commonly used equipment for rail inspection vehicles. In order to ensure the quality of the image obtained by the line array high-speed camera, it is necessary to adjust its line scanning speed in real time according to the speed of the rail inspection vehicle. Therefore, it is necessary to measure the speed of the rail inspection vehicle in real time. [0003] In the prior art, there are mainly two methods for detecting the vehicle speed of a rail inspection car. One method uses a wheel shaft pulse...
