On-board monitoring and event detection system for a machine with rotating components

Abstract:

An on-board monitoring and event detection system for a machine includes a powertrain. A vibration sensor adjacent one of a rotating component of the powertrain is configured to generate raw vibration data. A sensor controller is configured to receive the raw vibration data and generate condition indicators. At least one of a speed sensor, a torque sensor, a pressure sensor, or a temperature sensor, is operatively associated with the powertrain. A controller is distinct from the sensor controller and is configured to receive the condition indicators, and receive sensor signals from the at least one sensor and wherein the condition indicators and the sensor signals define operating characteristics of the powertrain. The controller is further configured to compare the operating characteristics of the powertrain to an event threshold and generate an event response if the operating characteristics exceed the event threshold for a time period exceeding a time threshold.
