Abstract

The invention provides a train wheel set bearing safety monitoring system based on a self-power-supply sensing network. The system comprises an energy collection device, a wireless sensor and a data analysis center, wherein the energy collection device is used for converting vibration mechanical energy generated in a train operation process into electric energy and outputting the electric energy to the wireless sensor; the wireless sensor works through the electric energy and is used for collecting the vibration acceleration data of the wheel set bearing in the train operation process by certain frequency and sending the vibration acceleration data to the data analysis center in real time; and the data analysis center is used for carrying out real-time analysis on received train wheel setbearing real-time vibration acceleration data sent from the wireless sensor. By use of the system, the real-time monitoring early warning of a bearing operation state is realized, and an effective technical means is provided for the service safety and the health management of trains.

Description

technical field [0001] The invention relates to the field of rail transit operation safety monitoring, in particular to a safety monitoring system for rail train wheel set bearings based on a self-powered sensor network. Background technique [0002] With the development of rail transit technology, more and more rail transit trains have been put into operation. The safety of train operation has become an important link to ensure the efficient and safe operation of rail transit, and the train wheel set bearing is an important part of the rail transit train running part. Part, its safety status has a non-negligible effect on the operation safety of the whole train. Therefore, the safety monitoring of rail train wheel set bearings has become a necessary content to ensure the safety of train operation. [0003] The existing traditional wheel-set bearing safety monitoring methods mainly include: monitoring methods based on temperature, monitoring methods based on oil sample anal...
