Abstract
A position control system for use with a mobile machine at a worksite is disclosed. The control system may have a location receiver configured to generate a location signal indicative of an actual location of a base station, a communication device configured to wirelessly communicate with the mobile machine, and a controller in communication with the location receiver and the communication device. The controller may be configured to store an assumed location of the base station in memory, make a comparison of the location signal with the assumed location, and selectively generate a control instruction for the mobile machine based on the comparison.
Claims18
A position control system for use with a mobile machine at a worksite, comprising:
- a location receiver configured to generate a location signal indicative of an actual location of a base station at the worksite;
- a communication device configured to wirelessly communicate with the mobile machine;
- and
- a controller in communication with the location receiver and the communication device, the controller being configured to:
- store a previously known location of the base station in memory;
- make a comparison of the actual location with the previously known location;
- and
- selectively generate a control instruction for the mobile machine based on the comparison, wherein the control instruction causes activation of a warning device when the comparison indicates a difference between the previously known and actual locations greater than a threshold value.
A method of monitoring a position of a base station at a worksite, the method comprising:
- receiving a location signal indicative of an actual location of the base station;
- making, by a controller, a comparison of the actual location with a previously known location of the base station;
- and
- selectively generating, by the controller, a control instruction for a mobile machine at the worksite based on the comparison, wherein the control instruction causes activation of a warning device when the comparison indicates a difference between the previously known and actual locations is greater than a first threshold value.
A non-transitory computer readable medium for use by a position control system, the computer readable medium having executable instructions stored thereon for performing a method of monitoring a position of a base station, the method comprising:
- receiving a location signal indicative of an actual location of the base station;
- making a comparison of the actual location with a previously known location of the base station;
- and
- selectively generating a control instruction for a mobile machine at a
- worksite based on the comparison, wherein the control instruction causes activation of a warning device when the comparison indicates a difference between the previously known and actual locations is greater than a first threshold value.
