Embodiment Construction
[0059] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0060] The movement variables of the support behavior are the action type and the action speed of the support. The order of the action types determines the action sequence of the support, and the action speed is affected by the power of the fluid supply. The decision-making principle of the two variables can be attributed to the coordination of the action sequence of the support group and the response regulation of the fluid supply power. The bilevel programming problem. Based on this, the idea of the intelligent decision-making method provided by the embodiment of the present invention is as follows: with the support adapting to the speed of the shearer (appropriate speed), precise action and stable pressure (precise stability) as the multiple decision-making objectives, control the timing sequence of any feasible support combination action The liq...

The invention provides an intelligent decision-making method for the propulsion behavior of a hydraulic support group following a machine, which belongs to the field of hydraulic support control, and aims to solve the problem that the current method will lead to poor adaptability of the support to follow the machine. Carry out timing planning for the follow-up action of the hydraulic support to determine the feasible set of the action sequence of the hydraulic support group's following-the-machine propulsion behavior; determine the adjustment range and adjustment accuracy of the liquid supply flow as the lower decision space, and determine each feasible support in the lower decision space The hydraulic power control sequence corresponding to the combined action control sequence; predict the average follow-up speed of the hydraulic support group and the pressure state evaluation score of the liquid supply system when each feasible support combined action control sequence controls the hydraulic support group; calculate each According to the overall satisfaction of all feasible support combination action control sequences, determine the support combination action control sequence and hydraulic supply power regulation sequence of the hydraulic support group following machine propulsion behavior.
Description
technical field [0001] The invention relates to the technical field of hydraulic support control, in particular to an intelligent decision-making method for hydraulic support group follow-up propulsion behavior. Background technique [0002] The coordinated advancement and precise control of fully mechanized mining equipment in the working face is one of the key core technologies of smart mines. Through the coordinated and intelligent operation of the fully mechanized mining equipment groups in the mining-loading-transportation-supporting process links, the full-mechanized coal mining face is realized. The process is a safe and efficient mining technology of "unmanned follow-up operation, manned safety inspection". Intelligent decision-making refers to self-sensing analysis and making control decisions based on the current state of equipment, spatial location information, production operation and safety rules, etc. The intelligent decision-making of fully mechanized mining ...
