Publication number: 20160125674Abstract: A computer-implemented method and a system for managing signals generated by onboard systems of a mobile equipment fleet, where each of the signals contain operating condition information associated with one of the items of the fleet. The system continuously receives the signals as transmitted by the onboard systems via a communications network. For each of the received signals, the system selects a rule from a rules database based on the equipment operating condition information in the received signal. The rule contains a cause and an action associated with an equipment operating condition. The system generates a report that includes the equipment operating condition, the cause and the action of the selected rule and transmits it to an operator device via the communications network.Type: ApplicationFiled: November 3, 2015Publication date: May 5, 2016Inventors: PAUL WOHLGEMUTH, ED BLANCHE, IAN PARSONS, PETER READ, KYLE GOGOLINSKI, MICHELLE NOER, DAVID GREENWOOD
