Finally, the controller executes step S103 to calculate the advancing distance according to the target pressure time sequence data, for example, a plurality of connection increasing pressure time sequence data or a plurality of continuous decreasing pressure time sequence data are respectively summed up to be used as the advancing distance; the plurality of connection increasing pressure time sequence data and the plurality of continuous decreasing pressure time sequence data can be respectively accumulated and summed, and the average value of the sum of the two values is calculated to be used as the advancing distance.

Specifically, when the working surface advancing distance within a certain period of time needs to be calculated, first, the controller executes step 201 to collect second historical pressure time sequence data of the hydraulic support in real time. And secondly, executing step S202, compressing and preprocessing the second historical time sequence data by using a revolving door algorithm, and storing changed data in the second historical pressure time sequence data to obtain second candidate pressure time sequence data, so that the data processing amount is reduced, and the working efficiency is further improved. Thirdly, executing the step S203 to judge whether the data quality stamp of the second candidate pressure time sequence data is 0, if the second candidate pressure time sequence data is removed, obtaining real-time pressure time sequence data, wherein the real-time pressure time sequence data comprises first current pressure time sequence data and first historical pressure time sequence data of a previous period adjacent to the first current pressure time sequence data, filtering interference data, further reducing data processing capacity, and improving accuracy and working efficiency; from this time, step S204 is executed to determine whether the absolute value of the difference between the first current pressure time series data and the first historical pressure time series data is greater than or equal to a preset data threshold, if yes, step S205 is executed to use the first current pressure time series data as first candidate pressure time series data, the first candidate pressure time series data includes the candidate current pressure time series data and candidate historical pressure time series data of a previous period adjacent to the candidate current pressure time series data, not only a large amount of useless data in a waveform stabilization period can be filtered, but also the problem of "jitter" of the sensor data of the hydraulic support push cylinder sensor, namely, an influence factor of small-amplitude fluctuation of data, is overcome, and the data accuracy and the working efficiency are further improved; otherwise, step S206 is executed to delete the first current pressure timing sequence data until all the real-time pressure timing sequence data are judged. Then, step S207 is executed to determine whether the difference between the current pressure time series data to be selected and the historical pressure time series data to be selected is greater than or equal to 0, if so, step S208 is executed, otherwise, step S209 is executed. Then, step S210 is executed to take the first continuously increasing pressure time series data and/or the first continuously decreasing pressure time series data as the target pressure time series data. Finally, step S211 is executed to sum the multiple first continuously increasing pressure time series data or the multiple first continuously decreasing pressure time series data to obtain a first advancing distance.
Wherein, the first advancing distance is the advancing distance of the fully mechanized coal mining face.
Wherein the data threshold is 10mm-50 mm.
According to the method for calculating the advancing distance of the fully mechanized coal mining face, the real-time pressure time sequence data of the hydraulic support are obtained, the continuous increasing pressure time sequence data and/or the continuous decreasing pressure time sequence data in the real-time pressure time sequence data are/is used as the target pressure time sequence data, and the advancing distance is calculated according to the target pressure time sequence data, so that the advancing distance of the working face is automatically calculated, and the accuracy and the working efficiency are improved.

Specifically, when the working face advancing distance needs to be calculated in a certain continuous time period, such as a certain day, a few weeks, a few months, or an accumulated advancing distance during the whole fully mechanized working face mining period, first, the controller executes step S301 to calculate the first advancing distance according to steps S201 to S211 in the second embodiment. Next, step S302 is executed to use the last first continuously increasing pressure time series data or the first continuously decreasing pressure time series data in step S210 as the initial pressure time series data in the current time period. Step S303 is executed to acquire second real-time pressure timing data of the hydraulic support in the second time period, and the second real-time pressure timing data may also be processed by the method of step S202 to step S206 in the second embodiment, so that the data processing amount is reduced, and the accuracy and the working efficiency are improved. Then, step S304 is executed to compare the initial pressure time sequence data with the first and second real-time pressure time sequence data in the second time period, when the initial pressure time sequence data is smaller than the first and second real-time pressure time sequence data, the first and second real-time pressure time sequence data are taken as second continuous increasing pressure time sequence data, and then the values of the adjacent second real-time pressure time sequence data are sequentially compared to obtain second continuous increasing pressure time sequence data and/or second continuous decreasing pressure time sequence data, that is, the determination method of the second continuous increasing pressure time sequence data and the second continuous decreasing pressure time sequence data is the same as the determination method of the first continuous increasing pressure time sequence data and the first continuous decreasing pressure time sequence data in the second embodiment. Next, step S305 is executed to take the second continuously increasing pressure time series data and/or the second continuously decreasing pressure time series data as the target pressure time series data. Then, step S306 is executed to perform cumulative summation on the plurality of second continuously increasing pressure time series data, or perform cumulative summation on the plurality of second continuously decreasing pressure time series data, so as to obtain a second advancing distance. Finally, step S307 is executed to sum the first advance distance and the second advance distance to obtain the advance distance.
The method for calculating the advancing distance of the fully-mechanized mining face comprises the steps of calculating a first advancing distance, taking the last first continuous increasing pressure time sequence data or the first continuous decreasing pressure time sequence data in the previous time period as the initial pressure time sequence data in the current time period, obtaining second real-time pressure time sequence data of a hydraulic support in the second time period, obtaining a second advancing distance according to the initial pressure time sequence data and the second real-time pressure time sequence data, and calculating the advancing distance according to the first advancing distance and the second advancing distance, so that the advancing distance of the working face in the continuous time period is automatically calculated, and the accuracy and the working efficiency are improved.
