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

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.
