Problems solved by technology

This overload will stress or strain the industrial machine, or can cause the industrial machine to lose its ability to safely control the bucket (eg, due to increased inertia from the load)

Embodiment Construction

[0019] The invention described herein relates to systems, methods, apparatus, and computer readable media associated with controlling the operation of industrial machinery based on a suspension of the industrial machinery. For example, the industrial machine includes a control system or controller that determines and / or monitors the suspended load. The suspended load of the industrial machine includes the weight of the bucket and the weight of the materials in the bucket. The controller is configured to determine and / or monitor the suspended load of the industrial machine for individual excavation operations and excavation operations for a period of time. If at any given time the controller determines that the suspended load (e.g., the instantaneous suspended load) is greater than or equal to a threshold (e.g., the rated suspended load "RLS"), the controller can control the suspended load based on the suspended load. Describe industrial machinery. For example, the controller...

Abstract

An industrial machine includes a dipper, a crowd actuation device, a hoist actuation device, a swing actuation device, one or more sensors, and a controller. The one or more sensors generate one or more signals related to a load within the dipper. The one or more signals are received by the controller. The controller determines, based on the one or more signals, whether the industrial machine is operating in an over-loaded condition by comparing a suspended load to a suspended load threshold value. If the suspended load is greater or equal to the suspended load threshold value, the controller takes an action to control the industrial machine. The action taken by the controller can include increasing, decreasing, or otherwise modifying a speed parameter or speed limit, increasing, decreasing, or otherwise modifying a force parameter, etc.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application No. 62 / 024,789, filed July 15, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to the control of industrial machinery. Background technique [0004] Industrial machinery such as electric or power shovels, cable shovels, etc. are used to perform excavation operations that remove material from, for example, mine deposits. Different industrial machines have different load capacities or suspended loads that they can support. The suspension capacity of industrial machinery is generally equivalent to the weight or quantity of materials in the bucket except for the weight of the bucket itself under normal conditions (such as dry working conditions, etc.) when the bucket is fully loaded. However, under certain conditions (such as after rain or snowmelt, denser material, falling ice crystallization...
