Abstract

The invention refers to controlling a digging operation of an industrial machine, and discloses systems, methods, devices, and computer readable media for controlling the operation of an industrial machine including one or more components. A method of controlling the industrial machine includes determining an accelerated speed related with an industrial machinery; determining a pushing retraction factor based on the accelerated speed; comparing the pushing retraction factor and a position of at least one of the one or more components of the industrial machine during a digging operation, determining a threshold pushing extraction factor; and setting a pushing speed value and a pushing extraction torque of a pushing driving device in a period based on the comparison between the pushing extraction factor and the threshold pushing extraction factor.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 31, 2011, an application number of 201180071748.5 (international application number of PCT / US2011 / 049946), and an invention title of "Controlling Excavation Operation of Industrial Machinery". [0002] Cross References to Related Applications [0003] This application claims the benefit of previously filed co-pending US Provisional Patent Application No. 61 / 480,603, filed April 29, 2011, which is hereby incorporated by reference in its entirety. technical field [0004] The present invention relates to controlling the excavation operations of industrial machinery such as electric rope excavators or powered excavators. Background technique [0005] Industrial machinery such as electric rope or power excavators, draglines, etc. are used to perform excavation operations that remove material from, for example, a mine deposit. In difficult mining environments...
