  • the geofence boundary 505 defines a permitted area 510 and a restricted region 515.
  • the permitted area 510 represents a region or area in which the mining machine 302 is permitted to operate in (for example, safely operate without a risk of being driven into a high wall, over a berm, or the like).
  • the mining machine 302 may freely move around the permitted area 510 based on one or more commands, such as, for example, a propel command, a crowd command, a swing command, or another command for controlling operation of the mining machine 302 (i.e., autonomous or automated commands or commands from an on-board or remote operator that cause the mining machine to move over the ground surface).
  • the restricted region 515 represents a region or area in which the mining machine 302 is not permitted to operate in. As one example, the restricted region 515 may represent an area in which operation of the mining machine 302 is unsafe.
  • the restricted region 515 completely surrounds the mining machine 302. However, in other embodiments, the restricted region 515 does not completely surround the mining machine 302. As one example, the restricted region 515 may be positioned on one or more sides of the mining machine 302. As illustrated in FIG. 5B, the restricted region 515 is positioned on two sides of the mining machine 302. Alternatively or in addition, in some embodiments, the restricted region 515 may define a region or area having another shape than illustrated in FIGS. 5 A and 5B. As one example, the restricted region 515 may be circular in shape, as illustrated in FIG. 5C. Accordingly, a shape of the restricted region 515 may be regular, irregular, or the like. Additionally, although a single restricted region 515 (and geofence boundary 505) is illustrated in FIGS. 5A-5C, it should be understood that multiple restricted regions 515 (and geofence boundaries 505) may be implemented.
  • the mining machine 302 is surrounded by a first operation zone 525 (for example, a first virtual operation zone 525) and a second operation zone 530 (for example, a second virtual operation zone 525).
  • a first operation zone 525 for example, a first virtual operation zone 525)
  • a second operation zone 530 for example, a second virtual operation zone 525.
  • the first operation zone 525 is positioned within the second operation zone 530. Accordingly, an area of the first operation zone 525 is smaller than an area of the second operation zone 530.
  • the first operation zone 525 and the second operation zone 530 are illustrated in FIGS. 5A-5C as being rectangular in shape, in some embodiments, the first operation zone 525, the second operation zone 530, or a combination thereof may be a different shape than illustrated.
  • the first operation zone 525, the second operation zone 530, or a combination thereof may replicate or mirror a shape depicting a natural boundary or perimeter of the mining machine 302. Accordingly, the first operation zone 525, the second operation zone 530, or a combination thereof may be irregular in shape.
  • the first operation zone 525 defines an area or region around the mining machine 302 that should not cross the geofence boundary 505 into the restricted zone 515. As seen in FIGS. 5 A-5C, the first operation zone 525 is defined by a set of perimeter points forming a first boundary 526 of the first operation zone 525. Accordingly, the first operation zone 525 functions to ensure that a natural perimeter of the mining machine 302 does not cross the geofence boundary 505 into the restricted zone 515. Since the physical position of the natural perimeter of the mining machine 302 is not known with 100% certainty, a buffer zone is used.
  • the depth or size of the first operation zone 525 (with respect to the natural perimeter of the mining machine 302) is directly proportional to an uncertainty in a current position of the mining machine 302. Additionally, in some embodiments, the depth of the first operation zone 525 dynamically changes as the uncertainty changes. For example, when the uncertainty is calculated to be different, the depth of the first operation zone 525 changes. In some embodiments, uncertainty is determined by a position monitoring system of the mining machine 302, such as a global positioning system, a GNSS unit, or the like. For example, an error value or a degree of confidence may be determined using the position monitoring system of the mining machine 302. In some embodiments, the error value or degree of confidence may be used as the uncertainty.
  • the depth or size of the first operation zone 525 is dynamically changed based on one or more components of the mining machine, such as a position or angle of a component of the mining machine 302. As one example, with reference to FIG.
  • a mast of the mining machine 302 may change position or angle during operation of the mining machine 302. As the position or angle of the mast changes, the natural perimeter of the mining machine 302 may also change. Accordingly, in some embodiments, the first operation zone 525 may be based on (or dynamically changed based on) a position or angle of a component of the mining machine 302.
  • the second operation zone 530 defines an area and region around the mining machine 302 outside of the first operation zone 525. As seen in FIGS. 5A-5C, the second operation zone 530 is defined by a set of perimeter points forming a second boundary 531 of the second operation zone 530.
  • the second operation zone 530 functions to cause the mining machine 302 to reduce propel references once the second operation zone 530 crosses the geofence boundary 505 into the restricted zone 515. Accordingly, as the second operation zone 530 enters the restricted zone 515, a speed of the mining machine 302 is controlled to slow the mining machine 302 down before the first operation zone 525 crosses the geofence boundary 505.
  • a distance or depth between the first boundary 526 of the first operation zone 525 and the second boundary 531 of the second operation zone 530 is static (represented in FIGS. 5A-5B by the double arrow labeled “D1-2”).
  • the distance or depth between the first boundary 526 of the first operation zone 525 and the second boundary 531 of the second operation zone 530 may be set by manufacturer, a machine administrator, or other machine personnel.
  • a distance or depth between the natural perimeter of the mining machine 302 and the second boundary 513 of the second operation zone 530 (represented in FIGS. 5A-5C by the double arrow labeled “DM-2”) may vary (for example, based on the depth or size of the first operation zone 525).
  • a distance or depth between the natural perimeter of the mining machine 302 and the second boundary 513 may change proportional to the change in size or depth of the first operation zone 530.
  • the distance or depth between the first boundary 526 of the first operation zone 525 and the second boundary 531 of the second operation zone 530 may remain the same.
  • the first boundary 526 of the first operation zone 525 and/or the second boundary 531 of the second operation zone 530 may dynamically change based on operational conditions of the mining machine 302.
  • the first boundary 526 of the first operation zone 525 may increase (for example, the value of DM-I may increase) when the mining machine 302 increases velocity.
  • the first boundary 526 of the first operation zone 525 may increase (for example, the value of DM-I may increase) when the mining machine is moving a certain direction. Based on the position of the mining machine 302, these operational conditions may be taken into account when setting the first operation zone 525.
  • the second boundary 531 may also dynamically change proportional to the change to the first boundary 526.
  • the restricted zone 515 may include a warning zone that is a distance from the geofence boundary 505.
  • the warning zone may be sensed by a sensor 310 of the mining machine 302.
  • the warning zone may not completely follow the geofence boundary 505, but rather only be implemented for a portion of the geofence boundary 505.
  • the warning zone may be a single stake in an area that emits a signal indicating that the mining machine 302 should avoid the area a certain distance around the stake.
  • the stake may signify a large hole that would disrupt operation of the mining machine 302.
  • the warning zone may include various priority levels.
  • a high priority level when the mining machine 302 enters the warning zone may indicate that the upcoming geofence 505 is situated at a cliff.
  • a medium priority level may indicated that the upcoming geofence 505 is situated at a wall.
  • the memory 405 also stores a set of geofence boundaries 600 (for example, the geofence boundary 505 as a set of perimeter points defining the restricted region 515), a set of operation zones 605 associated with the mining machine 302 (for example, the first operation zone 525 and the second operation zone 530 as sets of perimeter points defining the first boundary 526 and the second boundary 531, respectively).
