Problems solved by technology

[0004] In terms of the analysis algorithm for the periodic pressure of the working face, the existing research results have been stuck in the analysis of the pressure characteristics and laws of the working face by using the time-weighted average working resistance and the final resistance and other support load parameters, relying solely on the time-weighted average There are disadvantages in the analysis. The periodic compressive strength extracted during the analysis process does not match the actual compressive strength on site, resulting in a large deviation between the analysis results and the actual site.

Embodiment 1

[0058] like figure 1 As shown, the embodiment of the present invention provides a method for analyzing the periodic pressure of a coal mining face, including:

[0059] S101. Obtain the pressure value collected by the target support within the sampling time period, the number of the pressure value is at least two, and each pressure value corresponds to a collection time point;

[0060] In this step, the target support can be any hydraulic support used to control the mine pressure of the coal mining face; any time period in the coal mining face advancement process can be used as the sampling time period, and the sampling time The length of the sampling period is generally one month, and when the advancing speed of the working face is fast, the length of the sampling period can be shortened accordingly.

[0061] During the sampling period, the target support periodically collects pressure from the roof, and each collected pressure value corresponds to its collection time point. ...

Abstract

The embodiment of the invention discloses a coal face periodic pressure analysis method and device and electronic equipment, relates to the technical field of coal mine system big data processing, andcan enable an analysis result to be closer to field reality. The method comprises the following steps: acquiring a pressure value acquired by a target bracket in a sampling time period; constructinga first discrete data sequence for the pressure values according to an acquisition time sequence; obtaining a maximum value in the first discrete data sequence; constructing a maximum value set according to the maximum value and the serial number of the maximum value; for each maximum value in the maximum value set, executing the following operations: acquiring other maximum values of which the absolute value of the difference between the serial number in the maximum value set and the serial number of the maximum value is smaller than a preset value; judging whether the maximum value is greater than all the other maximum values or not; if so, taking the maximum value as an incoming pressure peak value; and according to the incoming pressure peak value and the acquisition time point of theincoming pressure peak value, calculating the periodic incoming pressure rule of the coal face.

Description

technical field [0001] The invention relates to the technical field of large data processing of coal mine systems, in particular to a method, device and electronic equipment for analyzing the periodic incoming pressure of a coal mining face. Background technique [0002] At present, my country's coal mining face is changing from automation to intelligence. The sign of intelligence is that the equipment has the ability of self-perception, self-correction, and self-decision-making. The intelligence of intelligent equipment depends on the perception and analysis of the environment. Intelligent analysis is the equipment The foundation of intelligence, the intelligent working face has a large amount of monitoring data, and the monitoring data of the support is on the order of millions. Such a large amount of data requires coal mine technicians to check and adjust one by one, eliminate artificial duplication and useless data, and analyze the process. The personnel caused great pain,...
