An Introduction of Data Logger Management Centre

In this paper we are an introduction of Data Logger Management Centre. Data logger system helps in finding-out the mistakes done by signal operators, loco pilots and the misbehavior of signaling systems. Thus are helping railways in preventing accidents and also reducing detentions to train services. Data logger is placed in the relay room. Data logger monitors the relay status and records its change with time stamp. Each data logger has number of data output ports for communicating the recorded information to the Central/ Local Fault Analyzing System. Data loggers are networked in daisy chain to a Front End Processor provided in central location, usually, divisional control office.
