Internet of things based notification system for derail accidents on railways

In this study, an internet of things-based notification system was developed for the early detection of derailment accidents, which are the most common accidents on railways. A derailment accident is a long-lasting type of accident that occurs when the wheels of a wagon or locomotive derail on a train and takes place along the railway until the train stops. For this reason, early notification of a derailed wagon by the driver is very important in minimizing the damage caused by the accident. For this reason, in this study, a system that notifies the driver via wireless communication in case of a delay accident has been developed. The system works on the principle that it is triggered as a result of an unusual shaking in the derailed wagon. The system consists of two modules, the machinist and wagon module, and there is hardware and software between them to provide long-range wireless communication. When a derailment accident occurs, the wagon module notifies the wagon in which the accident occurred via wireless broadcast, and on the receiver side, the machinist module in the locomotive informs the machinist about the derailed wagon. In this way, the train is stopped immediately and the accident is prevented from continuing further. The system developed with this aspect also prevents the damage caused by derailment accidents from increasing. In this study, the details and working principle of the developed system are given in detail and suggestions are made for future studies.
