Multisensor railway track geometry surveying system using raspberry pi

Electronics and Communication Engineering

This project is a cost effective yet vigorous solution to the problem of railway track geometry survey utilizing a method that is unique in the sense that while it is simple, the idea is completely novel and up till now untested. The project discusses the technical and design aspects in detail and also provides the proposed multi sensor railway track geometry surveying system. This project also presents the details of the implementation results of the MRTGS utilizing simple components inclusive of a GPS module. To improve the quality and comfort of railway passengers, there has been increased demands to reduce the level of noise and vibration, experienced during travel. Different researches have focused on reducing the level of vibration. Track irregularities are the main causes of vibration and thus carefully monitor the parameter to improve the ride quality. Vibration may arise vertically and laterally, in this vertical vibration is higher. Bridge damage status is monitored by the sensor and wireless modules, when the sensor not getting signal, immediately nearby wireless system notifies and alert or informs to the current train on the track. The above task can achieve through microcontrollers, GSM, LVDT. The same information can be passed to all trains coming on the track.
