IOT Based Event Logger for Railway Signaling

In railway systems, signaling plays a vital role in railway monitoring system which operates the trains in a safe manner and to find the signal failure as early as possible to avoid mean time between failure. Also signaling is helpful to find the fault location, cause of failure and to know all the train movements in the yard. At present, Signaling used in railways suffers from drawbacks like use of number of relays, circuit design cost, space required, cable cost, requires lot of time to identify and locate fault. An IoT Based event logger is proposed in this paper for railway signaling to monitor and log the data related to train movements in the yard and also to communicate the failure information to the signal maintainer immediately. Code is written for Signal blank condition in C language and data logger is used for investigation purpose in case of train accident and derailment of train. The performance of IoT based event logger is compared with real time signaling in railway systems.
