Implementation of trackside detectors for early warning of bearing and wheel defects

This paper describes the background, evolution, and commissioning of a network of Infra-red Hot Bearing and Hot Wheel Detectors (HBD/HWD) installed, in its first stage, on the QR Goonyella line and associated mine branches. The paper traces the establishment of the primary design parameters from an investigation of bearing failure mechanisms and an incident analysis of bearing failures on the QR Coal and Minerals operation. The design builds on previous analysis of HBD data by BHP Iron Ore to provide reliable data for early intervention to prevent derailments whilst minimising false stops. Because of the range of bearing types and sizes used by QR, the higher level of data analysis was considered essential. The analysis techniques and architecture of the system are discussed together with the design concepts and interfaces to other systems such as the Wheel Impact Load Detector (WILD). The system provides a high level of reliability through use of redundancy and graceful degradation. The final system incorporates Dragging Equipment Detection and the collection and logging of a range of formerly isolated alann systems. Data analysis has been enhanced with the inclusion of train running information and consist management information. The merged information is made available to various users via train radio, integration with CTC, GSM Short Messaging Service and LAN/WAN database access. The paper concludes with a description of the debugging and fine tuning during installation and commissioning which inevitably make projects of this nature both challenging and memorable.
