When connected to the break pipe, YARG (Yard Air Remote Gauge) collects pressure data from the head end of the train and converts it to the digital data. An intelligent wireless data module then minimize the amount of data to be sent by constantly reviewing the data and only transmitting the real time information when the change of data is detected. Connecting to the cellular network requires the use of a gateway. A gateway receives the data from wireless communication network and converts it so that it can be accessed by the end user over the internet. Data security feature such as access control is managed by the application software.
