Problems solved by technology

[0004] The present invention provides a high-speed railway vehicle vibration detection system and its detection method, which can effectively solve the problem mentioned in the above-mentioned background technology that the current detection data often receives external interference, resulting in statistical errors, so that the statistics cannot be achieved whether it is a vehicle problem or a track problem , and secondly, in the running speed, the vibration at the beginning is due to the vehicle speed not reaching the specified speed. In the middle period, the speed reaches the specified speed, but whether the vehicle runs without problems. Here are three different detection directions, and there are no problems mentioned in the prior art

Abstract

The invention discloses a high-speed railway vehicle vibration detection system. The system comprises a plurality of vibration sensors, a processing device, a transmission device and a display device.The vibration sensors are installed on a railway vehicle, vibration signals of the vehicle are detected, and the signals are converted into analog quantity signals. The processing device is used forreceiving signals of the vibration sensors, processing and analyzing the signals, and displaying a final result. The transmission device is used for normally receiving the signals of the vibration sensors, transferring the signals to the processing device, and transmitting the signals to the display device after the signals are processed by the processing device. The system is scientific and reasonable in structure and safe and convenient to use, the vibration sensors convert the vibration signals of the vehicle into the analog quantity signals, then the analog quantity signals are transmittedto the processing device through the transmission device, the processing device analyzes the analog quantity signals after processing is completed, and then signals are transmitted to the display device through the transmission device for normal detection.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to a high-speed railway vehicle vibration detection system and a detection method thereof. Background technique [0002] High-speed rail has different regulations in different countries, different times, and different scientific research and academic fields. The National Railway Administration of China defines China's high-speed rail as a passenger train dedicated railway with a design speed of more than 250 kilometers per hour and an initial operating speed of more than 200 kilometers per hour, and issued the corresponding "High-speed Railway Design Specifications" document. China's National Development and Reform Commission defines China's high-speed rail as a speed 250 kilometers and above standard new or existing railways, and promulgated the corresponding "medium and long-term railway network planning" documents, including some track lines with a speed of 200 kilometers per ho...
