Embodiment Construction

[0021] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0022] refer to figure 1 As shown, in the present invention, the image-based online state detection system of train wheels is set in the interval of the high-speed railway station, and the image acquisition device is installed at 6 fixed points along the track of the train movement, and the images are completely covered on the surface of the wheel and rail by collecting wheel image frames in sections After these images are recognized and processed, the current state of the wheel 7 is judged, and the spraying device is started to spray different colors on the abnormal state of the wheel 7 as a mark, providing a reference for further key repairs and maintenance.

[0023] The present invention is composed of main parts such as an information processing control host 1, an image acquisition device and an image acquisition lighting device, a po...

Abstract

The invention discloses a system for detecting the online state of high speed passenger train wheel sets. The system is characterized by comprising an information processing control host, a plurality of image acquiring devices and image acquiring and illuminating devices, a position detector, a speed detector pair, a connecting cable and a color spraying device, and the information processing control host is connected with the image acquiring devices and image acquiring and illuminating devices, the position detector, the speed detector pair and the color spraying device through connecting cables. By the adoption of the system, damage detecting and monitoring are conducted on the outside of all the wheel sets, flaw detection automation degree and efficiency are improved, and operation reliability of a high speed train is improved.

Description

technical field [0001] The invention relates to an online state detection system, in particular to an online state detection system for a wheel set of a high-speed railway passenger train. Background technique [0002] The wheel set of the high-speed railway passenger train in operation is in a state of rolling motion, so it is difficult to collect wheel surface images and carry out image-based online detection and monitoring. In the existing technology, it is impossible to perform image-based wheel dynamic detection to find abnormal wheels. , so as to improve the reliability of high-speed railway train operation. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a high-speed railway passenger train wheelset online state detection system. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] The high-speed railway pass...
