Embodiment Construction

[0033] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0034] Such as figure 1 As shown, the present invention first provides an image-based railway vehicle running direction recognition and axle speed measurement device, including a bracket 1 fixed at the bottom of the vehicle, an image recognition sensor 2, a characteristic image disk 3, a data acquisition and processing unit 4, a power supply 5 and other components. The axle 6 and the wheel 7 form a pair of wheels and are placed on the rail 8.

[0035] Specifically, combined with figure 1 As shown, the image recognition sensor 2 is fixed on the bracket 1 at the bottom of the vehicle, the image recognition sensor 2 is aimed downward at the characteristic image disk 3, and takes photos of the characteristic image disk 3 at different times, and processes the captured images, and the data acquisition process Unit 4 collects the signal and process...

Abstract

The invention discloses an image based railway vehicle moving direction recognition and shaft speed measurement device and method. A railway vehicle includes a chassis and shafts. The device includesan image recognition sensor, a feather image disk, and a data acquisition processing unit; the image recognition sensor is arranged on the chassis; two line segments which incline to each other are arranged on the outer periphery of the feature image disk; a distance between the two line segments are gradually increased or decreased regularly; the feature image disk is arranged on the corresponding shaft and rotates coaxially with the shaft; the image recognition sensor aims at the feature image disk to shoot the distance of the rotating feature disk at different moments and converts the distance into signals; the data acquisition processing unit acquires and processes the signals, the shaft speed of the shaft can be measured during running of the railway vehicle, and the moving directionof the railway vehicle can be determined. The image based railway vehicle moving direction recognition and shaft speed measurement device and method can solve the problem how to measure the shaft speed of the railway vehicle and determine the moving direction of the vehicle, and can further improve the real accuracy of measurement and recognition.

Description

technical field [0001] The invention belongs to the technical field of railway vehicle measurement and control, and relates to an image-based railway vehicle running direction recognition and axle speed measurement device and method. Background technique [0002] At present, most of the measurement methods for the axle speed of railway vehicles are measured by the speed measuring gear method or through the speed measuring radar. Influenced by factors such as idling and wheel skidding during braking, the measured vehicle speed is inaccurate. The test error of the speed measuring radar at different operating speeds is relatively large, and it can only measure the speed, but cannot determine the direction of the vehicle. Contents of the invention [0003] In order to overcome the defects in the prior art, an image-based device and method for identifying the running direction of railway vehicles and measuring the axle speed is provided to solve the problem of how to judge the...
