Patent Images
1. A method comprising:
- receiving sensor data from a position sensor or a pressure sensor mounted in a manifold of at least one engine to collect data for a throttle valve of the at least one engine, the sensor data indicative of a bad on the at least one engine from one or more fleet devices, wherein the sensor data describes a throttle position of the at least one engine, wherein the load includes a mechanical device connected to the at least one engine;
comparing the sensor data to a load signature;
starting a timer when the sensor data matches the load signature;
determining a management function based on the timer; and
generating a message including the management function.

Abstract
In one example, fleet devices are monitored. The fleet devices include engines. A controller, such as an engine controller or centralized controller, receives sensor data indicative of a load on the engine from one or more of the fleet devices. The controller analyzes the load from the sensor data to identify a management function. The controller generates a message including the management function.

8. A method comprising:
-
receiving sensor data from an engine control unit electrically connected to one or more fuel injectors of an engine, the sensor data indicative of a load on the engine of one or more fleet devices; analyzing, using a processor, the load from the sensor data to identify a management function; calculating a maintenance interval for the management function, wherein the sensor data includes injection time data indicative of an operation of one or more fuel injectors of the engine and the maintenance interval is calculated as a function of the injection time data; and generating, using the processor, a message including the management function. - View Dependent Claims (9, 10, 11)
