Operation monitoring system for machine and method thereof
First Claim
1. An operation monitoring system for a machine having a frame and a dump body, the operation monitoring system comprising:
- an inertial measurement unit mounted on the dump body of the machine, the inertial measurement unit comprising at least one accelerometer disposed to measure an acceleration of the dump body and generate a first signal indicative thereof, and at least one gyroscope disposed to measure a rotation of the dump body and generate a second signal indicative thereof;
a position determination unit present on-board the machine, the position determination unit configured to determine a position of the machine, and generate a third signal indicative thereof;
a time logging unit in communication with the inertial measurement unit and the position determination unit, the time logging unit configured to record a time entry in response to generation of at least one of the first signal, the second signal and the third signal, and generate a fourth signal indicative thereof; and
a processing unit in communication with the inertial measurement unit, the position determination unit and the time logging unit to receive the first signal, the second signal, the third signal and the fourth signal, the processing unit configured to determine one or more operation states of the machine based at least in part on one of the received signals, wherein the one or more operation states include at least one of a bunching state, corresponding to when the machine is waiting for a loading or an unloading, or a wasting state, corresponding to at least when the machine is stationary and is not waiting for a loading or an unloading, wherein the machine is determined to be in the wasting state when;
the first signal indicates zero acceleration of the dump body;
the second signal indicates zero rotation of the dump body;
the third signal indicates a position of the machine coinciding neither with the position of a loading site or a dumping site; and
the fifth signal indicates the machine is substantially stationary.
