Abstract
A material transfer vehicle transfers material to a container. A level of material in the container is detected, and a transfer rate of material from the material transfer vehicle to the container is controlled based upon the detected fill level. The transfer rate can be controlled using a plurality of different configurable unload parameters.
Claims20
A computer implemented method, comprising:
- accessing a configurable unloading operation parameter, wherein accessing the configurable unloading operation parameter comprises:
- accessing a cutoff threshold fill level;
- and
- accessing a taper threshold fill level;
- detecting a fill level of material unloaded into a container by a material transfer vehicle;
- generating an unloading rate command based on the configurable unloading operation parameter and the fill level, wherein generating the unloading rate command comprises:
- comparing the fill level to the cutoff threshold fill level to generate a cutoff threshold comparison result;
- and
- when the cutoff threshold comparison result indicates that the fill level meets the cutoff threshold fill level, generating the unloading rate command to stop an unloading operation based on the cutoff threshold comparison result;
- and
- generating an unloading control signal to control an unloading subsystem based on the unloading rate command.

An unload control system configured to control a material transfer vehicle to perform an unloading operation, the unload control system comprising:
- a parameter accessing system configured to access a configurable unloading operation parameter, wherein the configurable unloading operation parameter comprises a taper threshold fill level;
- a fill level generator configured to identify a fill level of material unloaded into a container by the material transfer vehicle;
- an unload rate processing system configured to generate an unloading rate command based on the configurable unloading operation parameter and the fill level, wherein the unload rate processing system comprises:
- a cutoff threshold comparison system configured to obtain a cutoff threshold fill level, compare the fill level to the cutoff threshold fill level to generate a cutoff threshold comparison result and, when the cutoff threshold comparison result indicates that the fill level meets the cutoff threshold fill level, generate the unloading rate command to stop the unloading operation based on the cutoff threshold comparison result, and
- a taper threshold comparison system configured to compare the fill level to the taper threshold fill level to obtain a taper threshold comparison result and, when the taper threshold comparison result indicates that the fill level meets the taper threshold fill level, generate a tapered unloading rate command;
- and
- a control signal generator configured to generate an unloading control signal to control an unloading subsystem based on the unloading rate command.
4 more elements
A computer system, comprising:
- at least one processor;
- and
- a data store, storing computer executable instructions which, when executed by the at least one processor, cause the at least one processor to perform steps, comprising:
- accessing a configurable unloading operation parameter;
- detecting a fill level of material unloaded into a container by a material transfer vehicle;
- generating an unloading rate command, based on the configurable unloading operation parameter and the fill level, to taper an unload rate at which material is transferred from the material transfer vehicle to the container, after the fill level of the material in the container reaches a taper threshold fill level, and as the fill level of the material in the container approaches a desired fill level;
- and
- generating an unloading control signal to control an unloading subsystem based on the unloading rate command.
