A Stationary System of Non-contact Temperature Measurement and Hot Box Detecting

What is it about?

In this paper we propose an intelligent stationary system of uninterrupted non-contact temperature measurement and detection of overheated bearing of train. The proposed measurement system is a stand-alone class, based on remote infrared measurement and recognition of hot lid of axle bearing. The measurement system is useful for continuous maintenance without traffic interruption. It consists of three parts: measurement device, alert device and personal computer with virtual instrument and appropriate database. The measurement device is based on infrared detector installed on both railway sides in the same axis as wheel axle. The whole system is installed on three locations, which are located 500 meters apart. The communication among system parts is done using RS232/485 interfaces and radio modems. This system has a vital role in: keeping railroad operations safe, preventive maintenance and avoidance of damaging of axle wheel bearings in railway.

Why is it important?

In this paper, we propose the design of a stationary system of infrared remote monitoring and fault detection of overheated axle-boxes in a railway. The concept of continuous measurement of hot-boxes temperature and continuous detection of bearing faults was successfully realized. Our system has the ability of detect the fault early on, which would improve the safety of mass railway transport. Moreover, it provides reliable failure-detection and helps in the reduction of derailments caused by hot-boxes. In addition, main role in derailment prevention is made better.
