Dynamic detection system and method for train wheel set inner side distance

Abstract

The invention relates to a dynamic detection system for the train wheel set inner side distance. The system comprises a first axle counting sensor, a train identity identification encoder, a second axle counting sensor, a third axle counting sensor, a fourth axle counting sensor, a laser displacement sensor set and a fifth axle counting sensor, all of which are sequentially arranged in the advancing direction of a train. The first axle counting sensor, the train identity identification encoder, the second axle counting sensor, the third axle counting sensor, the fourth axle counting sensor, the laser displacement sensor set and the fifth axle counting sensor are all connected to a control module in a control box. A PCI control acquisition card is further arranged in the control box. The control module is further connected with a communication module. The PCI control acquisition card communicates with a server through the communication module. A laser baffle is arranged on the laser displacement sensor and rotationally arranged on the laser displacement sensor through a rotary shaft. The rotary shaft is connected with an output shaft of a drive motor.

Description

technical field [0001] The invention belongs to the technical field of detection, and relates to a train detection device, in particular to a dynamic detection system and method for the inner distance of a train wheel pair; the detection system can efficiently, dynamically and accurately detect the inner distance of a train wheel Statistical analysis and prediction of detection data to improve the safety factor of train operation. Background technique [0002] The inner distance of a train wheel set refers to the horizontal distance between the inner planes of two rims on the same train wheel set. Whether the train can pass the turnout smoothly and whether it runs safely and stably is directly related to the change of the inner distance parameter of the wheel. The change of the inner distance parameter is one of the strictly stipulated dimensions in the standard geometric parameters of the train wheel set. According to the standard, the use limit of the inner distance of th...

Problems solved by technology

The system composition is complex, the calculation process is cumbersome, and is greatly affected by optical factors. It is generally used for comprehensive detection of geometric parameters of train wheelsets

[0008] Although the above detection methods can detect the inner distance of train wheelsets, the detection accuracy and detection efficiency can no longer meet the needs of high-speed train operation.
