Problems solved by technology

[0003] Such tasks and other tasks / jobs / operations may be long, routine, lengthy and time-consuming, preventing the operator from maintaining a high level of performance and operation of the underground loader
Additionally, the operator may not be able to calculate the optimum operating conditions for an operating underground loader, as optimum operation depends on many parameters that the operator may not be able to handle during operation
As a result, the quality of performance of the underground loader during operation may not be optimal
Furthermore, some tasks / operations may be designed to be performed by an operator on a wheel loader, for example in hazardous areas or in low visibility conditions, which is undesirable

Embodiment Construction

[0017] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0018] now refer to figure 1 and figure 2 , an exemplary worksite 100 is shown. Worksite 100 is illustrated in the illustration as a mining area. However, in various other embodiments, worksite 100 may embody and / or include, for example, a landfill, quarry, construction site, or any other type of worksite. refer to figure 2 , shows a front view of machine 130 operating at worksite 100 . As seen therein, worksite 100 includes terrain 102 having one or more sidewalls 104 , a floor 106 , and a ceiling 108 . Each of the one or more side walls 104, the floor 106, and the ceiling 108 may include a profile. In one embodiment, a profile may be defined as a 2D (2-dimensional) representation of geometric parameters assoc...

Abstract

A method for operating an underground loader is disclosed. The method includes detecting, by a controller, a first position of the subterranean loader within the worksite. The method also includes determining, by the controller, a position of the dump pit within the worksite. Further, the method includes determining, by the controller, a route for the underground loader to carry from the first location to a location of the dump pit. Further, the method includes controlling, by the controller, movement of the underground loader along the route until a position of the dump pit. The method also includes moving, by the controller, an implement assembly of the subterranean loader based on the topographic profile along the route and the height of the dam defined at the edge of the dump pit.

Description

technical field [0001] The invention relates to an underground machine for dumping piles of material on a construction site. More specifically, the present invention relates to a system and method for controlling underground machinery operating on a worksite. Background technique [0002] Earth moving machines such as excavators, shovel loaders, bulldozers, loaders, etc. are used throughout the world to perform a variety of tasks. An example is underground mining / ore extraction, where extensive dozing and / or dumping operations are required. During such extraction, one or more earth moving machines (such as underground loaders) need to be operated. Typically, underground loaders are manually operated. An operator drives the underground loader to the underground mining site, then controls and operates the loader within the worksite until the desired task is completed. [0003] Such tasks and other tasks / jobs / operations can be long, routine, lengthy and time consuming, prev...
