Railyard train detection and early warning system

A method of monitoring railyard worker protection system, the method comprising:

• initializing a plurality of train detection modules each located at a boundary of a railyard, a plurality of train alert modules distributed within the railyard, and a plurality of personal alert modules configured to be carried by railyard workers, the initializing comprising configuring the modules to report data in the desired rate, format, and interface via a wireless mesh communication network;
• reading, from one or more of the train detection modules, train alert modules, and personal alert modules, train detection and individual sensor health data, the train detection modules configured to detect a train in the railyard on at least one railway track and a direction of travel of the train thereon, the train detection modules each having a first plurality of sensors configured to simultaneously detect the train crossing the boundary of the railyard and further configured to generate a detection signal in response thereto;
• reporting and informing railyard workers and administration of sensor health data via the wireless mesh communication network;
• transmitting, by one or more of the train detection modules, the detection signal via the wireless mesh communications network to the plurality of train alert modules in response to the train entering the railyard based on the detected direction of travel for indicating arrival of the train to the railyard in response to detection thereof by one or more of the train detection modules;
• not transmitting, by one or more of the train detection modules, the detection signal via the wireless mesh communications network to the plurality of train alert modules in response to the train exiting the railyard based on the detected direction of travel for indicating departure of the train from the railyard in response to detection thereof by one or more of the train detection modules;
• and
• transmitting, by one or more of the train alert modules, the detection signal transmitted thereto via the wireless mesh communications network to at least one personal alert module when the at least one personal alert module is in proximity thereto;
• reporting, by the at least one personal alert module, arrival of the train entering the railway yard to railway workers and administration via the wireless mesh communication network in response to the one or more of the train detection modules detecting the direction of travel indicating the train is entering into the railyard and the at least one personal alert module is in proximity thereto.
