PERFORMANCE-BASED HAULAGE MANAGEMENT SYSTEM
First Claim
1. A haul route management system, comprising:
- a condition monitoring system in data communication with a machine operating in a work environment and configured to collect performance data associated with the machine;
a torque estimator communicatively coupled to the condition monitoring system and configured to determine a drive axle torque of the machine and estimate a total effective grade associated with the machine based on the drive axle torque;
a performance simulator communicatively coupled to the torque estimator and the condition monitoring system, wherein the performance simulator is configured to;
compare the estimated total effective grade with a threshold level;
simulate, if the estimated total effective grade exceeds the threshold level, a design performance of the machine based on the estimated total effective grade;
compare design performance data with the collected performance data;
perform a payload analysis of the machine if the collected performance data is inconsistent with the design performance data; and
establish a payload limit of the machine based on the payload analysis.

Abstract
A method for managing haul routes in work environments comprises collecting performance data associated with a machine operating in a work environment. The method also includes determining a drive axle torque of the machine and estimating a total effective grade associated with the machine based on the drive axle torque. The estimated total effective grade is compared with a threshold level and, if the estimated total effective grade exceeds the threshold level, a design performance of the machine may be simulated based on the calculated total effective grade. Design performance data is compared with the collected performance data, and a payload limit of the machine is adjusted if the design performance is inconsistent with collected performance data.
