On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
Example one

Referring to fig. 1, a coal cutting cycle analysis method based on hydraulic support setting force includes the following steps:
and S102, dividing the hydraulic supports of the working face into m groups, wherein each group contains n hydraulic supports, and one hydraulic support in each group is provided with a mine pressure detection sensor.
It will be appreciated that the number of sets of hydraulic supports in this step, and the number of hydraulic supports in each set, may be determined based on field practice. The non-electrohydraulic control system recovers the working face, and a coal mining machine is not provided with a sensor which can be used for measuring the position of the coal mining machine.

It should be noted that the mine pressure value is uploaded to the aboveground detection host computer in real time, and the mine pressure monitoring data of the existing mine pressure monitoring system of the coal mine can be acquired through communication protocols such as texts, ftp, web services or direct reading databases.
S106, analyzing and obtaining all initial supporting force generation moments of each hydraulic support provided with the mine pressure detection sensor according to the first data set, and generating a second data set C according to a time sequencem×n＝{t1,t2,...,tjIn the formula, tjThe moment when the initial supporting force occurs.
In the step, as the hydraulic supports are operated according to the 'descending, moving and ascending', the original mine pressure data is monitored through each support, and all the initial supporting force occurrence moments of each hydraulic support can be obtained through analysis.
As a possible implementation manner, analyzing all the initial force generating moments of each hydraulic support can be implemented by using a technical scheme related to judgment of initial force and end-of-cycle resistance in publication No. CN 112302720A. Referring to FIG. 2, the initial support force point and the end-of-cycle resistance point are shown.
Step S108, according to the first data set and the second data set, generating a third data set T { (T) according to the hydraulic support frame number and the initial force generating time of the initial force in a time sequence1,N1),(t2,N2),...,(tj,Nj) In the formula, NjAt the moment t of initial setting forcejCorresponding hydraulic support frame number.
In this step, the third data set T is a hydraulic support frame number obtained by initial support force inversion.
Step S110, acquiring a minimum value and a maximum value of the hydraulic support frame number in the third data set, and generating a fourth data set S ═ { XMin ] according to a time sequence1,XMax1,XMin2,XMax2,...,XMink,XMaxkWherein, XMinkIs a minimum value, XMaxkIs the maximum value, and k is the number of minimum and maximum values.
It will be appreciated that the minima and maxima in the fourth data set are regularly arranged in an order that crosses over one another. Referring to fig. 3, the minimum and maximum values regularly cross each other.
And S112, judging the size relationship between the maximum value and the minimum value in the fourth data set and the number median of the frame number, and calculating to obtain the total number of coal cutting cycles based on the size relationship. The size relationship can be divided into the following two cases.
The first case:
when each maximum value is more than or equal to the frame number median and each minimum value is less than or equal to the frame number median, calculating the total number C of coal cutting cycles in the analysis time periodt＝Cu+CdWherein, CuNumber of maxima, CdIs the number of minimum values.
The second case:
deleting the maximum value and a minimum value that appears in pair with the maximum value from the fourth data set when the maximum value is less than the frame number median;
when the minimum value is greater than the median frame number, the minimum value and a maximum value that appears in pair with the minimum value are deleted from the fourth data set.
And then calculating the total number of the coal cutting cycles according to a total number formula of the coal cutting cycles provided by the first situation.
According to the coal cutting cycle analysis method provided by the embodiment of the invention, the initial support force analysis result of the hydraulic support of the stope face is converted into data of time and the frame number of the hydraulic support through dimension conversion, the frame number data of the position is inverted, the automatic analysis of the coal cutting cycle of the stope face is realized, a feasible means is provided for reporting and monitoring the total number of the coal cutting cycle of a coal mine, an effective way of progress pushing analysis is provided for the research of the mine pressure rule of the roof of the working face, and the management level of the roof of the coal mine is favorably improved.
Specifically, the calculation method of the frame number median is as follows:
As a possible implementation manner, in the m groups of hydraulic supports, there are n-1 hydraulic supports without the mine pressure detection sensors between the hydraulic supports with the mine pressure detection sensors in the two adjacent groups. That is to say, in the hydraulic support sequence, one support pressure monitoring sensor is installed every n supports, so that a hydraulic support list set L ═ n,2 n.. m × n } where the mine pressure detection sensor is installed can be obtained. This is usually done during the actual production process.
Advantageously, in order to eliminate noise interference caused by inversion data, the data in the third data set is smoothed by a moving average method before the minimum value and the maximum value of the frame number in the third data set are acquired and the fourth data set is generated.
Example two
Wherein the same or corresponding parts as in the first embodiment are given the same reference numerals as in the first embodiment. For the sake of simplicity, only the differences between the second embodiment and the first embodiment will be described.
There are many methods for obtaining the minimum and maximum values of the frame number in the third data set and generating the second data set. The following alternative implementations are provided in this embodiment.
And acquiring a minimum value and a maximum value of the frame number in the third data set by adopting a sliding window method to generate a fourth data set. Referring to fig. 3, the method includes the following steps:
step S1081, initializing a time sequence;
step S1082, establishing a sliding window and traversing window elements;
the window element refers to the frame number data.
Step S1083, when the queue element is full, replacing the queue head element with a new queue tail element to be input;
step S1084, judging whether the first element of the queue is a maximum value or a minimum value, and under the condition that the first element of the queue is judged to be the maximum value or the minimum value, re-finding out the maximum value or the minimum value of the queue; under the condition that the judgment is negative, inputting a queue tail element;
step S1085, solving the maximum value and the minimum value of the queue.
The maximum and minimum values of the queue are the fourth data set generated from the minimum and maximum values of the frame number in the third data set.
The sliding window algorithm can solve the sub-element problem of the array/character string, can convert the nested loop problem into the single loop problem, and reduces the time complexity.
Compared with the prior art, the method provided by the second embodiment of the invention adopts a sliding window mode to count the coal cutting cycle number in a dynamic maximum value and a dynamic minimum value mode, so that the automatic analysis of the coal cutting cycle of the coal face is realized. The false alarm of the coal cutting cycle number reported manually is reduced to a certain extent.
