Abstract:  An Advanced portable instrument to monitor, detect, and record the horizontal and vertical accelerations of the railway vehicles (railway coaches, wagons and locomotives, etc.) as well as of railway tracks has been designed and developed by incorporating the state of the art technology suitable for this purpose. The design/technology has been perfected by conducting repeated field trials on the instrument in association with the engineers of RDSO, Lucknow. The designed instrument based on 89C52 Micro-controller technology, is a major step in the direction of advance instrumentation for Indian Railways. Oscillation monitoring system continuously measures vertical and lateral accelerations at any desired location on the floor of a railway vehicle and simultaneous measurement of distance from fixed points of track on real time basis. It is an advanced portable instrument to measure and record oscillations of railway vehicle, while in motion. The system is so rugged that it can work in non air-conditioned environment and withstand vibration of ā€˜1gā€™ in all three orthogonal axes without any problem. Based on this measurement, analysis can be carried out on railway track conditions. The unit has been designed with large storage capacity and displays locations of bad spots along with other required information, which are registered over the threshold value.
