Abstract:
A system for reporting a production status of a haulage vehicle in a substantially real-time basis with respect to a production goal, the system comprising: a sensor on-board the vehicle for sensing a weight of a present load carried by the vehicle over a haul cycle; a device for sensing a dumping of the present load and providing a signal indicative thereof; a clock for accumulating an elapsed operating time of the vehicle; an accumulator responsive to the signal from the sensing device for adding the weight of the present load to a total weight that is a sum of the weights of previous loads carried by the vehicle during the elapsed operating time, thereby incrementing the total weight to a new value; a memory for storing a production rate goal for the cycle over which the vehicle is carrying the present and previous loads; a processor in communication with the memory, the accumulator and the clock; the processor including means for (1) comparing the production rate goal and an actual rate of production derived from the elapsed operating time and the new value of the total weight and (2) providing an output signal indicating a relative value of the actual production rate with respect to the production rate goal; and a display for providing to an operator of the vehicle an indication of the relative value of the actual production rate.
