Development of wireless system for temperature measuring in axle-bearings of railway vehicles

Abstract

The constant increase in the speed of transport and the constant tendency to optimize and reduce transport costs conditioning that the reliability of technical systems becomes one of the key requirements. Failures of such systems can cause very serious consequences for the environment, safety and health of people, and therefore it is very important to pay special attention to the efficiency of their functioning. One of such systems is the railway, which is among the most complex technical and technological systems. The basic requirements for railways are to be reliable, efficient and cost-effective compared to the other modes of transport. Railway failures do not happen often, but when they happen, the consequences are derailments followed by extensive material damage and loss of human life. In addition, there are large economic losses due to downtime and repair of railway infrastructure. One of the frequent causes of derailments is malfunction of axle-bearings of railway vehicles, which is manifested by an increasing in their temperature. In this sense, this paper presents the development of a new method of temperature detection in the axle-bearings of railway vehicles.
