[0033] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0034] The following describes the method, device, electronic equipment and medium for dynamically evaluating the support quality of a hydraulic support according to an embodiment of the present application with reference to the accompanying drawings.

[0035] Figure 1 A schematic flow chart of a method for dynamically evaluating the support quality of a hydraulic support provided in an embodiment of the present application.

[0036] like Figure 1 As shown, the dynamic assessment method for the hydraulic support quality includes the following steps:

[0037] Step 101, constructing a dynamic evaluation index system for the support quality of hydraulic supports based on various monitoring indicators of the hydraulic supports.

[0038] In order to ensure the timeliness of the support quality assessment, the monitoring index can refer to a variable that can obtain the index data in real time. In an optional embodiment, the monitoring index includes but is not limited to the pressure u1 of a single column of the hydraulic support, the pressure difference u2 of the hydraulic support column, the maximum downward shrinkage of a single column of the hydraulic support u3, the extension difference u4 of the hydraulic support column, the roll angle u5 of the hydraulic support top beam, the pitch angle u6 of the hydraulic support top beam, the roll angle u7 of the hydraulic support base, the pitch angle u8 of the hydraulic support base, the inclination angle u9 of the hydraulic support shield beam, the combined force u10 of the hydraulic support top beam, the action point u11 of the combined force of the hydraulic support top beam, the height u12 of the hydraulic support, the pressure u13 of the hydraulic support guard plate, the pressure u14 of the hydraulic support balance jack, and the opening state u15 of the hydraulic support safety valve. The above-mentioned monitoring indicators form a dynamic evaluation index system for the quality of hydraulic support support U={u1, u2, u3, u4, u5, u6, u7, u8, u9, u10, u11, u12, u13, u14, u15}.

[0039] Step 102, obtaining the real-time monitoring value of each monitoring index in the hydraulic support support quality dynamic evaluation index system at at least one time, and determining the positive evaluation value and the negative evaluation value of each real-time monitoring value.

[0040] The real-time monitoring value of the monitoring indicator at at least one moment refers to the real-time monitoring value of the monitoring indicator at one moment or the real-time monitoring value at multiple moments. When at least one moment refers to multiple moments, the sampling period between two adjacent moments may be the same. As an example and not a limitation, the sampling period may be one minute.

[0041] For any monitoring indicator, the positive evaluation value and negative evaluation value of the real-time monitoring value of the monitoring indicator respectively refer to the degree of satisfaction and dissatisfaction of the real-time monitoring value with respect to a certain property represented by the monitoring indicator (such as stability, safety, bearing capacity, etc.); among which, the degree of satisfaction indicates the degree to which the hydraulic support performs well in this property, and the degree of dissatisfaction indicates the degree to which the hydraulic support performs poorly in this property.

[0042] As an example, the positive evaluation value and the negative evaluation value of each real-time monitoring value may be determined by a bipolar fuzzy analysis method.

[0043] Among them, the positive electrode evaluation value and the negative electrode evaluation value corresponding to each real-time monitoring value constitute a bipolar evaluation set.

[0044] The positive evaluation values ​​and negative evaluation values ​​corresponding to the real-time monitoring values ​​of each monitoring indicator at each moment constitute the bipolar fuzzy evaluation matrix R of the dynamic evaluation index system of hydraulic support support quality. As an example, a row in the bipolar fuzzy evaluation matrix R is a bipolar evaluation set corresponding to the real-time monitoring values ​​of each monitoring indicator at a certain moment, and a column is a bipolar evaluation set corresponding to the real-time monitoring value of a monitoring indicator at each moment.

[0045] Taking the above 15 monitoring indicators as an example, the bipolar fuzzy evaluation matrix R is as follows:

[0046] R=

[0047]

[0048] in, Corresponding to the first Column, indicating the The monitoring indicators are The set of bipolar evaluation sets corresponding to the real-time monitoring values ​​at each moment, .

[0049]

[0050]

[0051] in, Indicates a moment, , Indicates The next moment The bipolar evaluation set corresponding to the real-time monitoring value of the monitoring indicator is ( ), Indicates The next moment The positive evaluation value of the real-time monitoring value of the monitoring indicator, Indicates The next moment The negative evaluation value of the real-time monitoring value of a monitoring indicator.

[0052] Step 103, for any monitoring indicator in the dynamic evaluation index system of hydraulic support support quality, determine the first positive ideal point and the first negative ideal point corresponding to the positive evaluation value of the real-time monitoring value of the monitoring indicator, and determine the second positive ideal point and the second negative ideal point corresponding to the negative evaluation value of the real-time monitoring value of the monitoring indicator.

[0053] The first positive ideal point refers to the positive ideal point of the positive evaluation value of the real-time monitoring value of the monitoring indicator, representing the optimal state value of the positive evaluation value of the real-time monitoring value; the first negative ideal point refers to the negative ideal point of the positive evaluation value of the real-time monitoring value of the monitoring indicator, representing the worst state value of the positive evaluation value of the real-time monitoring value.

[0054] The second positive ideal point refers to the positive ideal point of the negative evaluation value of the real-time monitoring value of the monitoring indicator, representing the optimal state value of the negative evaluation value of the real-time monitoring value; the second negative ideal point refers to the negative ideal point of the negative evaluation value of the real-time monitoring value of the monitoring indicator, representing the worst state value of the negative evaluation value of the real-time monitoring value.

[0055] As an example, when obtaining real-time monitoring values ​​of various monitoring indicators of the hydraulic support at one or more moments, for any monitoring indicator, a predetermined first positive ideal point, a first negative ideal point, a second positive ideal point and a second negative ideal point can be obtained.

[0056] Step 104, for any moment, based on the difference between the positive evaluation value of the real-time monitoring value of each monitoring indicator at that moment and the corresponding first positive ideal point and first negative ideal point, as well as the difference between the negative evaluation value of the real-time monitoring value of each monitoring indicator at that moment and the corresponding second positive ideal point and second negative ideal point, determine the support quality deviation value of the hydraulic support at that moment.

[0057] For the real-time monitoring value of any monitoring indicator at any moment, the difference between the positive pole evaluation value of the real-time monitoring value and the corresponding first positive ideal point, as well as the difference between the negative pole evaluation value of the real-time monitoring value and the second positive ideal point, respectively intuitively reflect the degree to which the positive pole evaluation value and the negative pole evaluation value of the real-time monitoring value deviate from the optimal state; the difference between the positive pole evaluation value of the real-time monitoring value and the corresponding first negative ideal point, as well as the difference between the negative pole evaluation value and the second negative ideal point, respectively intuitively reflect the degree to which the positive pole evaluation value and the negative pole evaluation value of the real-time monitoring value deviate from the worst state.

[0058] Therefore, based on the difference between the positive evaluation value and the first positive ideal point and the first negative ideal point, as well as the difference between the negative evaluation value and the second positive ideal point and the second negative ideal point, the support quality deviation value of the hydraulic support determined can accurately and objectively reflect the deviation between the support quality of the hydraulic support and the expected optimal support state and the worst support state.

[0059] Step 105: Determine a dynamic evaluation result of the support quality of the hydraulic support based on the support quality deviation value of the hydraulic support at at least one moment.

[0060] When evaluating the support quality of the hydraulic support, for each moment, it can be determined whether the support quality deviation value at that moment is greater than the reference deviation value. If the support quality deviation value at that moment is greater than the reference deviation value, it means that the support quality of the hydraulic support at that moment is good; if the support quality deviation value at that moment is less than or equal to the reference deviation value, it means that the support quality of the hydraulic support at that moment is poor. Among them, the reference deviation value is the support quality deviation value threshold, which is used to evaluate the support quality of the hydraulic support and determine the dynamic evaluation result of the support quality of the hydraulic support.

[0061] The reference deviation value has a direct impact on the accuracy of the dynamic evaluation results. The following is an explanation of how to determine the reference deviation value:

[0062] As an example, when obtaining the real-time monitoring values ​​of various monitoring indicators of the hydraulic support at a moment, a predetermined reference deviation value may be obtained.

[0063] As another example, when obtaining real-time monitoring values ​​of various monitoring indicators of the hydraulic support at multiple times, a reference deviation value can be determined based on the support quality deviation values ​​at multiple times. For example, the average of the support quality deviation values ​​at multiple times is used as the reference deviation value.

[0064] In this embodiment, a dynamic evaluation index system for the support quality of a hydraulic support is constructed based on each monitoring index of the hydraulic support; the real-time monitoring value of each monitoring index in the dynamic evaluation index system for the support quality of the hydraulic support is obtained at at least one moment, and the positive evaluation value and the negative evaluation value of each real-time monitoring value are determined; for any monitoring index, the first positive ideal point and the first negative ideal point corresponding to the positive evaluation value of the real-time monitoring value of the monitoring index are determined, and the second positive ideal point and the second negative ideal point corresponding to the negative evaluation value of the real-time monitoring value of the monitoring index are determined; for any moment, based on the difference between the positive evaluation value of the real-time monitoring value of each monitoring index at the moment and the corresponding first positive ideal point and first negative ideal point, and the difference between the negative evaluation value of the real-time monitoring value of each monitoring index at the moment and the corresponding second positive ideal point and second negative ideal point, the support quality deviation value of the hydraulic support at the moment is determined; based on the support quality deviation value of the hydraulic support at at least one moment, the dynamic evaluation result of the support quality of the hydraulic support is determined. Based on the real-time monitoring values ​​of each monitoring indicator in the dynamic evaluation index system of hydraulic support support quality, the real-time online dynamic evaluation of the hydraulic support support quality can be realized, which has good real-time performance and can provide a reference basis for the adjustment of hydraulic support support parameters in a timely manner. In addition, based on the positive evaluation value and negative evaluation value of the real-time monitoring value, the support quality of the hydraulic support is evaluated from both positive and negative aspects, which improves the accuracy of the support quality evaluation results.

[0065] This embodiment provides another method for dynamically evaluating the support quality of hydraulic supports. Figure 2 A schematic flow chart of a method for dynamically evaluating the support quality of a hydraulic support provided in an embodiment of the present application.

[0066] like Figure 2 As shown, the method for dynamic assessment of hydraulic support quality may include the following steps:

[0067] Step 201, constructing a dynamic evaluation index system for the support quality of hydraulic supports based on various monitoring indicators of the hydraulic supports.

[0068] Step 202: obtaining the real-time monitoring value of each monitoring index in the hydraulic support support quality dynamic evaluation index system at at least one moment.

[0069] Step 203, for the real-time monitoring value of any monitoring indicator in the hydraulic support support quality dynamic evaluation indicator system at any time, determine whether the real-time monitoring value is within the corresponding normal monitoring value range.

[0070] The normal monitoring value interval can be predetermined; if the real-time monitoring value of the monitoring indicator is within the corresponding normal monitoring value interval, it means that the real-time monitoring value is a normal value; if the real-time monitoring value of the monitoring indicator is not within the corresponding normal monitoring value interval, it means that the real-time monitoring value is an abnormal value.

[0071] As an example but not a limitation, the normal monitoring value ranges corresponding to each monitoring indicator are as follows:

[0072] The normal monitoring value range of the pressure u1 of a single column of the hydraulic support is [initial support force value, end-of-cycle resistance value], which can generally be [18MPa, 38.5MPa]; the normal monitoring value range of the pressure difference u2 of the hydraulic support column is [0, 5MPa]; the normal monitoring value range of the maximum downward contraction u3 of a single column of the hydraulic support is [0, 50cm]; the normal monitoring value range of the expansion and contraction difference u4 of the hydraulic support column is [0, 20cm]; the normal monitoring value range of the roll angle u5 of the hydraulic support top beam is [-10°, 10°]; the normal monitoring value range of the pitch angle u6 of the hydraulic support top beam is [0, 10°]; the normal monitoring value range of the roll angle u7 of the hydraulic support base is [-10°, 10°]; the pitch angle u8 of the hydraulic support base is [0, 10°] The normal monitoring value interval of the inclination angle u8 is [0, 10°]; the normal monitoring value interval of the inclination angle u9 of the hydraulic support shield beam is [30°, 50°]; the normal monitoring value interval of the hydraulic support top beam resultant force u10 is [400MPa, 500MPa]; the normal monitoring value interval of the hydraulic support top beam resultant force action point u11 is [-20cm, 20cm]; the normal monitoring value interval of the hydraulic support height u12 is [the lowest value of the support column, the maximum mining height of the working face]; the normal monitoring value interval of the hydraulic support guard plate pressure u13 is [0, 20MPa]; the normal monitoring value interval of the hydraulic support balance jack pressure u14 is [0, 20MPa]; the normal value of the hydraulic support safety valve opening state u15 is 0.

[0073] Step 204, in response to the real-time monitoring value being within the corresponding normal monitoring value interval, the real-time monitoring value is standardized based on the set first non-negative interval to obtain a positive evaluation value of the real-time monitoring value of any monitoring indicator in the dynamic evaluation index system of hydraulic support support quality at any time; based on the set first non-positive interval, a random value is selected to obtain a negative evaluation value of the real-time monitoring value of any monitoring indicator in the dynamic evaluation index system of hydraulic support support quality at any time.

[0074] In the case where the real-time monitoring value is within the corresponding normal monitoring value interval, in order to make the positive evaluation value play a leading role, the right endpoint value of the first non-negative interval is greater than the absolute value of the left endpoint value of the first non-positive interval.

[0075] As a possible implementation, the first non-negative interval is [0, 1], and the first non-positive interval is [-0.5, 0]. As another possible implementation, the first non-negative interval is [0, 1], and the first non-positive interval is [-0.4, 0].

[0076] As an example, the real-time monitoring value of the monitoring indicator can be standardized by the following formula:

[0077]

[0078] in, is the real-time monitoring value of the monitoring indicator. is the maximum value in the normal monitoring value interval corresponding to the monitoring indicator, is the minimum value in the normal monitoring value interval corresponding to the monitoring indicator, It is the positive evaluation value of the real-time monitoring value of the monitoring indicator.

[0079] As an example, a random number selection algorithm may be used to select a random value from the first non-positive interval as the negative pole evaluation value.

[0080] Step 205, in response to the real-time monitoring value not being within the corresponding normal monitoring value interval, a random value is selected based on a set second non-negative interval to obtain a positive evaluation value of the real-time monitoring value of any monitoring indicator in the dynamic evaluation index system for hydraulic support quality at any time; based on the set second non-positive interval, the real-time monitoring value is standardized to obtain a negative evaluation value of the real-time monitoring value of any monitoring indicator in the dynamic evaluation index system for hydraulic support quality at any time.

[0081] Among them, the right endpoint value of the first non-negative interval is greater than the right endpoint value of the second non-negative interval, and the left endpoint value of the first non-positive interval is greater than the left endpoint value of the second non-positive interval.

[0082] When the real-time monitoring value is not within the corresponding normal monitoring value interval, in order to make the negative evaluation value play a dominant role and avoid completely negative evaluation, the right endpoint value of the first non-negative interval is smaller than the absolute value of the left endpoint value of the first non-positive interval.

[0083] As a possible implementation, the second non-negative interval is [0, 0.5], and the second non-positive interval is [-1, 0]. As another possible implementation, the second non-negative interval is [0, 0.4], and the second non-positive interval is [-1, 0].

[0084] Regardless of whether the real-time monitoring value is a normal value or an abnormal value, this application quantitatively evaluates the real-time monitoring value based on non-negative intervals and non-positive intervals.

[0085] The contents of random value selection and standardization of real-time monitoring values ​​in this step can refer to the relevant description in the aforementioned step 204.

[0086] It should be noted that, for monitoring indicators u1-u14, the positive evaluation value and negative evaluation value of the real-time monitoring value of the monitoring indicator can be determined based on step 204 or step 205; for monitoring indicator u15, its real-time monitoring value is a switch state. When the real-time monitoring value is 0, it means that the hydraulic support safety valve is not open. At this time, it can be determined that the positive evaluation value of the real-time monitoring value is 1, and the negative evaluation value is 0; when the monitoring value is 1, it means that the hydraulic support safety valve is open. At this time, it can be determined that the positive evaluation value of the real-time monitoring value is 0, and the negative evaluation value is -1.

[0087] Step 206, for any monitoring indicator, determine the first positive ideal point and the first negative ideal point corresponding to the positive evaluation value of the real-time monitoring value of the monitoring indicator, and determine the second positive ideal point and the second negative ideal point corresponding to the negative evaluation value of the real-time monitoring value of the monitoring indicator.

[0088] As an example, when obtaining the real-time monitoring values ​​of various monitoring indicators of the hydraulic support at multiple times, for any monitoring indicator, the maximum positive evaluation value is selected from the positive evaluation values ​​corresponding to the real-time monitoring values ​​of the monitoring indicator at multiple times as the first positive ideal point for the dynamic evaluation of the support quality of the hydraulic support; the minimum positive evaluation value is selected from the positive evaluation values ​​corresponding to the real-time monitoring values ​​of the monitoring indicator at multiple times as the first negative ideal point for the dynamic evaluation of the support quality of the hydraulic support; the maximum negative evaluation value is selected from the negative evaluation values ​​corresponding to the real-time monitoring values ​​of the monitoring indicator at multiple times as the second positive ideal point for the dynamic evaluation of the support quality of the hydraulic support; the minimum negative evaluation value is selected from the negative evaluation values ​​corresponding to the real-time monitoring values ​​of the monitoring indicator at multiple times as the second negative ideal point for the dynamic evaluation of the support quality of the hydraulic support.

[0089] As an example, combining the following formula, The process of obtaining the first positive ideal point, the first negative ideal point, the second positive ideal point and the second negative ideal point corresponding to each monitoring indicator is described as follows:

[0090]

[0091]

[0092]

[0093] Indicates The positive ideal point set corresponding to the monitoring index includes the first positive ideal point and the second positive ideal point ; Indicates that from The monitoring indicators are Among the positive electrode evaluation values ​​corresponding to the real-time monitoring values ​​at each moment, the maximum positive electrode evaluation value is selected as the The first positive ideal point corresponding to the monitoring index ; Indicates that from The monitoring indicators are Among the negative electrode evaluation values ​​corresponding to the real-time monitoring values ​​at each moment, the maximum negative electrode evaluation value is selected as the The second positive ideal point corresponding to the monitoring index .

[0094] Indicates The set of negative ideal points corresponding to the monitoring indicators includes the first negative ideal point and the second negative ideal point ; Indicates that from The monitoring indicators are Among the positive electrode evaluation values ​​corresponding to the real-time monitoring values ​​at each moment, the minimum positive electrode evaluation value is selected as the first The first negative ideal point corresponding to the monitoring index , Indicates that from The monitoring indicators are Among the negative electrode evaluation values ​​corresponding to the real-time monitoring values ​​at each moment, the minimum negative electrode evaluation value is selected as the The second negative ideal point corresponding to the monitoring index .

[0095] Step 207, for any moment, based on the distance between the positive evaluation value of the real-time monitoring value of each monitoring indicator in the dynamic evaluation index system for hydraulic support quality at that moment and the corresponding first positive ideal point, and the distance between the negative evaluation value of the real-time monitoring value of each monitoring indicator in the dynamic evaluation index system for hydraulic support quality at that moment and the corresponding second positive ideal point, determine the first distance.

[0096] As an example, the first distance is determined based on the absolute value of the distance between the positive evaluation value of the real-time monitoring value of each monitoring indicator in the dynamic evaluation index system for hydraulic support quality and the corresponding first positive ideal point, and the absolute value of the distance between the negative evaluation value of the real-time monitoring value of each monitoring indicator in the dynamic evaluation index system for hydraulic support quality and the corresponding second positive ideal point.

[0097] Among them, the first distance is determined based on the absolute value of the distance between the positive evaluation value of the real-time monitoring value of each monitoring indicator in the hydraulic support support quality dynamic evaluation index system at this moment and the corresponding first positive ideal point, and the absolute value of the distance between the negative evaluation value of the real-time monitoring value of each monitoring indicator in the hydraulic support support quality dynamic evaluation index system at this moment and the corresponding second positive ideal point, including: for any monitoring indicator in the hydraulic support support quality dynamic evaluation index system, based on the positive evaluation value of the real-time monitoring value of the monitoring indicator at this moment and the corresponding first positive ideal point, and the absolute value of the distance between the negative evaluation value of the real-time monitoring value of the monitoring indicator at this moment and the corresponding second positive ideal point, determine the average of the absolute values ​​of the first distances; determine the first distance based on the average of the absolute values ​​of the first distances corresponding to each monitoring indicator in the hydraulic support support quality dynamic evaluation index system.

[0098] As an example and not a limitation, the first distance may be determined by the following formula:

[0099]

[0100] Indicates The first distance at this moment, Indicates The next moment The positive evaluation value of the real-time monitoring value of the monitoring index , and the corresponding first positive ideal point The distance between Indicates The next moment Negative evaluation value of the real-time monitoring value of the monitoring index , and the corresponding second positive ideal point The distance between Indicates taking the absolute value.

[0101] Step 208, determine the second distance based on the distance between the positive evaluation value of the real-time monitoring value of each monitoring indicator in the dynamic evaluation index system for hydraulic support support quality at the time and the corresponding first negative ideal point, and the distance between the negative evaluation value of the real-time monitoring value of each monitoring indicator in the dynamic evaluation index system for hydraulic support support quality at the time and the corresponding second negative ideal point.

[0102] As an example, the second distance is determined based on the absolute value of the distance between the positive evaluation value of the real-time monitoring value of each monitoring indicator in the dynamic evaluation index system for hydraulic support support quality at the moment and the corresponding first negative ideal point, and the absolute value of the distance between the negative evaluation value of the real-time monitoring value of each monitoring indicator in the dynamic evaluation index system for hydraulic support support quality at the moment and the corresponding second negative ideal point.

[0103] Among them, based on the positive evaluation value of the real-time monitoring value of each monitoring indicator in the hydraulic support support quality dynamic evaluation index system at this moment and the absolute value of the distance between the corresponding first negative ideal point, and the negative evaluation value of the real-time monitoring value of each monitoring indicator in the hydraulic support support quality dynamic evaluation index system at this moment and the absolute value of the distance between the corresponding second negative ideal point, the second distance is determined, including: for any monitoring indicator in the hydraulic support support quality dynamic evaluation index system, based on the positive evaluation value of the real-time monitoring value of the monitoring indicator at this moment and the absolute value of the distance between the corresponding first negative ideal point, and the negative evaluation value of the real-time monitoring value of the monitoring indicator at this moment and the absolute value of the distance between the corresponding second negative ideal point, determine the average of the absolute values ​​of the second distances; based on the average of the absolute values ​​of the second distances corresponding to each monitoring indicator in the hydraulic support support quality dynamic evaluation index system, determine the second distance.

[0104] As an example and not limitation, the second distance may be determined by the following formula:

[0105]

[0106] Indicates The second distance at this moment, Indicates The next moment The positive evaluation value of the real-time monitoring value of the monitoring index , and the corresponding first negative ideal point The distance between Indicates The next moment Negative evaluation value of the real-time monitoring value of the monitoring index , and the corresponding second negative ideal point The distance between.

[0107] Step 209: Determine the support quality deviation value of the hydraulic support at this moment based on the first distance and the second distance.

[0108] As an example, the support quality deviation value can be calculated by the following formula:

[0109]

[0110] For the The support quality deviation value at the moment is: The larger it is, the better the support quality of the hydraulic support is. For the The first distance corresponding to the moment, For the The second distance corresponding to the moment.

[0111] Step 2010: Determine a dynamic evaluation result of the support quality of the hydraulic support based on the support quality deviation value of the hydraulic support at at least one moment.

[0112] As an example, in the case where there are multiple hydraulic supports, the dynamic evaluation results of the support quality of the hydraulic supports are determined based on the support quality deviation values ​​of the hydraulic supports at at least one moment, including: determining a reference deviation value based on the support quality deviation value of each hydraulic support at at least one moment; comparing each support quality deviation value with the reference deviation value to determine the number of support quality deviation values ​​greater than the reference deviation value; and determining the dynamic evaluation results of the support quality of the hydraulic supports based on the number.

[0113] The reference deviation value calculated based on actual monitoring data can more objectively and truly reflect the actual situation of the hydraulic support quality, reduce the interference of human factors, and improve the objectivity and reliability of the reference deviation value.

[0114] Optionally, based on the support quality deviation value of each hydraulic support at at least one moment, an average deviation value is determined, and the average deviation value is used as a reference deviation value.

[0115] In order to avoid the interference of accidental factors on the support quality assessment results and improve the accuracy of the support quality assessment results, as a possible implementation method, if the number of support quality deviation values ​​greater than the reference deviation value is greater than the set number, it is determined that the support quality of multiple hydraulic supports is good; if the number of support quality deviation values ​​greater than the reference deviation value is less than or equal to the set number, it is determined that the support quality of multiple hydraulic supports is poor.

[0116] As another possible implementation, the support quality grades of multiple hydraulic supports may be determined according to the number of support quality deviation values ​​greater than the reference deviation value, and the support quality grade may be used as a dynamic evaluation result.

[0117] In this embodiment, according to whether the real-time monitoring value of the monitoring indicator is within the corresponding normal monitoring value interval, the positive evaluation value and the negative evaluation value of the real-time monitoring value are determined based on the corresponding non-negative interval and non-positive interval. When the real-time monitoring value is within the corresponding normal monitoring value interval, the positive evaluation value plays a leading role. When the real-time monitoring value is not within the corresponding normal monitoring value interval, the negative evaluation value plays a leading role, thereby improving the assessment accuracy of the support quality.

[0118] In an optional embodiment, the present application combines the real-time monitoring values ​​of each monitoring indicator of a hydraulic support at 5 moments to evaluate the support quality of the hydraulic support:

[0119] As shown in Table 1, Table 1 includes the real-time monitoring values ​​of 15 monitoring indicators at 5 moments.

[0120]

[0121] Table 1

[0122] As shown in Table 2, Table 2 includes the bipolar evaluation sets corresponding to each real-time monitoring value.

[0123]

[0124] Table 2

[0125] The positive ideal point sets corresponding to each monitoring indicator determined by the bipolar evaluation set of each monitoring indicator at 5 moments are:

[0126] I 0 =[(0.98,-0.27),(0.6,-0.02),(0.4,-0.24),(1,-0.25),(0.95,-0.01),(1,-0.31),(0.75,-0.05),(0.5,-0.01),(0.8,-0.03),(1,-0.02),(0.75,-0.04),(0.75,-0.02),(0.25,-0.04),(1,-0.19),(1,0)]

[0127] The negative ideal point sets corresponding to each monitoring indicator determined by the bipolar evaluation set of each monitoring indicator at 5 moments are:

[0128] I *=[(0,-0.78),(0,-0.46),(0,-0.48),(0,-0.5),(0.65,-0.47),(0.2,-0.8),(0.75,-0.42),(0.5,-0.22),(0.25,-0.26),(0,-0.42),(0.5,-0.42),(0.63,-0.31),(0,-0.48),(0.5,-0.44),(0,-1),]

[0129] The first distance and the second distance at each moment determined based on the positive ideal point set and the negative ideal point set corresponding to each monitoring indicator are respectively: , ; , ; , ; , ; , .

[0130] The support quality deviation values ​​at each moment determined based on the first distance and the second distance corresponding to each moment are: c1=0.59, c2=0.66, c3=0.55, c4=0.48, c5=0.40.

[0131] According to the support quality deviation value at each moment, it can be seen that the support quality of the hydraulic support at moment 5 is poor. It can also be qualitatively seen from Table 1 that at moment 5, the safety valve of the hydraulic support is opened, the hydraulic support is depressurized, and the support quality is poor.
