[0002] Hydraulic supports are hydraulic power devices that use liquid pressure to generate supporting force and achieve automatic relocation for roof support and management.

They are also suitable for horizontal layered top coal caving longwall mining faces with steeply inclined extra-thick coal seams.

[0003] Current technology mainly uses pressure data to analyze the motion of hydraulic supports. However, the motion analysis obtained in this way is not accurate and will affect the control operation of hydraulic supports.

[0029] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0030] Figure 1 This is a schematic diagram of an exemplary embodiment of a hydraulic support status determination method proposed in this disclosure, as shown below. Figure 1 As shown, the method for determining the state of a hydraulic support includes the following steps:

[0031] S101 periodically acquires the real-time column pressure and real-time stroke values ​​of the hydraulic support.

[0032] In this embodiment of the disclosure, the real-time pressure value and real-time stroke value of the hydraulic support can be obtained based on sensors.

[0033] The real-time column pressure value is the pressure value borne by the support column of the hydraulic support. It should be noted that the real-time column pressure value may include information such as the magnitude and direction of the pressure, as well as the location of the pressure. There are no restrictions here, and it can be set according to the actual design requirements.

[0034] The real-time stroke value is used to represent the movement data of the hydraulic strut. It should be noted that the real-time stroke value can include values ​​such as the distance, direction, and trajectory of movement, without any limitations. It can be set according to the actual design requirements.

[0035] It should be noted that the sensors used to acquire different real-time sensor data can be different. For example, the stroke value of the hydraulic support movement can be measured using a displacement sensor, the column pressure of the hydraulic support can be measured using a pressure sensor installed on the column, and the top beam pressure can be measured using a pressure sensor installed on the top beam. There can be one sensor or multiple sensors. The processor can receive data from multiple sensors and process it to generate real-time column pressure and stroke values.

[0036] In this embodiment of the disclosure, the data acquisition period can be preset and can be changed according to actual design needs. For example, the acquisition period can be 10s, 20s, etc., and no limitation is made here.

[0037] S102, determine the first state information of the hydraulic support based on the real-time stroke value, and determine the second state information of the hydraulic support based on the real-time column pressure value.

[0038] In this embodiment, the first state information describes the working state of the hydraulic support under pressure, and may include various states, such as support state, column raising state, column lowering state, etc. The second state information describes the movement state of the hydraulic support, and may include various states, such as support shifting state, sliding state, and stationary state, etc. It should be noted that sliding refers to the process of using a sliding cylinder to push the scraper conveyor forward, and support shifting refers to the process of lifting the hydraulic support, raising the base, and then retracting the hydraulic cylinder to automatically move the hydraulic support forward.

[0039] In this embodiment, after acquiring real-time sensor data, the data can be analyzed to determine the current state information of the hydraulic support. It should be noted that various analysis methods are possible. For example, multiple thresholds can be pre-set, and the real-time sensor data can be compared with these thresholds to determine the current state information of the hydraulic support. For instance, taking the second state information as an example, if the real-time column pressure value is less than or equal to the first column pressure threshold, the current support column can be considered to be in a lifting state; if the real-time column pressure value is greater than the first column pressure threshold, the current support column can be considered to be in a supporting state. It should be noted that due to different downhole environments, different hydraulic support models, and other factors, these thresholds are not fixed and need to be set according to the actual situation.

[0040] Optionally, the state information of the hydraulic support can also be determined by the rate of change of sensor data. By acquiring historical hydraulic data and obtaining the rate of change of hydraulic data within a certain range, the current working state of the hydraulic support can be determined.

[0041] S103, based on the first state information and the second state information, update the working node of the hydraulic support.

[0042] In this embodiment, due to the complexity of downhole conditions, errors may exist in the measurement of real-time cylinder pressure and real-time stroke values. If the hydraulic support's status is analyzed solely based on the real-time cylinder pressure or real-time stroke values, misjudgments can easily occur. For example, in a single status assessment, the first status information might be "pushing" and the second status information might be "supporting." In practice, these two states cannot coexist. Therefore, it can be determined that the currently acquired real-time cylinder pressure and real-time stroke values ​​contain errors, or that the current working state of the hydraulic support is abnormal, requiring confirmation.

[0043] Therefore, in this embodiment of the disclosure, after obtaining the first state information and the second state information of the hydraulic support, the first state information and the second state information can be comprehensively analyzed to determine the current true working state of the hydraulic support, and the true working state is updated to the working node of the hydraulic support. It should be noted that the true working state can include multiple types, for example, it can include abnormal state, moving state, pushing state, and support state, etc., without any limitation here.

[0044] Furthermore, when the actual working state is abnormal, alarm information needs to be generated and sent to relevant operators for handling to prevent damage caused by abnormal operation of hydraulic supports or sensor failure.

[0045] In this embodiment, the real-time cylinder pressure and real-time stroke values ​​of the hydraulic support are first acquired periodically. Then, a first state information of the hydraulic support is determined based on the real-time stroke value, and a second state information of the hydraulic support is determined based on the real-time cylinder pressure value. Finally, the operating nodes of the hydraulic support are updated based on the first and second state information. Therefore, by comprehensively analyzing the real-time cylinder pressure and real-time stroke values ​​of the hydraulic support, the state information of the hydraulic support can be obtained more comprehensively and accurately, while preventing errors in the analysis results due to errors in a single data point.

[0046] In the above embodiments, the first state information of the hydraulic support is determined based on the real-time stroke value, and can also be determined by... Figure 2 To further explain, the method includes:

[0047] S201, obtain the historical stroke value of the hydraulic support.

[0048] In this embodiment of the disclosure, the historical stroke value of the hydraulic support can be stored in the storage space of the electronic device or in the storage space of the server for easy retrieval and use when needed, without any limitation.

[0049] It should be noted that historical travel values ​​can be processed data. This includes data that can be filtered out if there are obvious errors. Optionally, all historical travel values ​​can be converted into data with a uniform format and units to improve the speed and accuracy of subsequent data processing.

[0050] S202, based on real-time stroke value and historical stroke value, determine the first state information of the hydraulic support.

[0051] In this embodiment of the disclosure, after obtaining the historical travel value, a first rate of change is determined based on the real-time travel value and the historical travel value, and the first state information of the hydraulic support is determined based on the first rate of change.

[0052] Optionally, a travel value variation curve can also be generated from existing travel values, such as... Figure 3 As shown, the first rate of change is determined based on the slope of the change curve, where the horizontal axis is the time axis and the vertical axis is the travel value.

[0053] The first state information typically includes two states: a moving support state and a pushing support state. In this embodiment, in response to a first rate of change being greater than a first rate of change threshold and less than a second rate of change threshold, the first state information is determined to be a moving support state; in response to a first rate of change being greater than a third rate of change threshold and less than a fourth rate of change threshold, the first state information is determined to be a pushing support state. It should be noted that the first, second, third, and fourth rate of change thresholds are preset and can be varied according to actual downhole conditions, hydraulic support type, design requirements, etc., and are not limited here.

[0054] In this embodiment, the historical stroke values ​​of the hydraulic support are first obtained, and then the first state information of the hydraulic support is determined based on the real-time stroke value and the historical stroke value. Therefore, by obtaining the historical stroke values ​​of the hydraulic support and analyzing the real-time stroke values, the current first state information of the hydraulic support can be more accurately determined based on historical data.

[0055] In the above embodiments, the second state information of the hydraulic support is determined based on the real-time column pressure value, and can also be determined by... Figure 4 To further explain, the method includes:

[0056] S401, obtain the historical column pressure value of the hydraulic support.

[0057] In this embodiment of the disclosure, the historical column pressure value of the hydraulic support can be stored in the storage space of the electronic device or in the storage space of the server for easy retrieval and use when needed, without any limitation.

[0058] It should be noted that historical bar pressure values ​​can be processed data. Data with obvious errors can be filtered out. Optionally, all historical bar pressure values ​​can be converted into data with a uniform format and units to improve the speed and accuracy of subsequent data processing.

[0059] S402, based on real-time column pressure values ​​and historical column pressure values, determines the second rate of change.

[0060] In this embodiment of the disclosure, after obtaining the historical column pressure value, a second rate of change is determined based on the real-time column pressure value and the historical column pressure value, and the second state information of the hydraulic support is determined based on the second rate of change. Figure 5 As shown, a column pressure value change curve can be generated by comparing real-time column pressure values ​​with historical column pressure values, and the second rate of change at each point on the column pressure curve can be determined based on the slope of the change curve, where the horizontal axis is the time axis and the vertical axis is the column pressure value.

[0061] S403, determine the second state information of the hydraulic support based on the second rate of change.

[0062] In practice, the second state information typically includes three states: column lowering, column raising, and support status. Figure 5 As shown by the curve, the corresponding rate of change is different under different states. Therefore, the second state information of the current hydraulic support can be determined by comparing multiple thresholds of the rate of change of the column pressure.

[0063] In this embodiment, in response to a second rate of change being greater than a fifth rate of change threshold and less than a sixth rate of change threshold, the second state information is determined to be a column lowering state; in response to a second rate of change being greater than a seventh rate of change threshold and less than an eighth rate of change threshold, the second state information is determined to be a column raising state; and in response to a second rate of change being less than a ninth rate of change threshold, the second state information is determined to be a support state. It should be noted that the fifth, sixth, seventh, eighth, and ninth rate of change thresholds are pre-set and can be varied according to actual downhole conditions, hydraulic support type, and design requirements, etc., and are not limited here.

[0064] In this embodiment, the historical column pressure value of the hydraulic support is first obtained. Then, based on the real-time column pressure value and the historical column pressure value, a second rate of change is determined. Finally, the second state information of the hydraulic support is determined based on the second rate of change. By obtaining the historical column pressure value of the hydraulic support and analyzing the real-time column pressure value, the second state information of the current hydraulic support can be more accurately determined based on historical data.

[0065] It should be noted that, through Figure 3 and Figure 5 It can also be seen that when there is a turning point or turning interval between two adjacent states of the hydraulic support, such as... Figure 5 As shown, there is a transition interval between the descending and ascending bar states. Within this transition interval, it is possible that the following is happening: Figure 3 The diagram shows the shifting and sliding operations. As a possible scenario, similar shifting and sliding operations may also be in progress before and after the turning point, requiring analysis based on the specific data values.

[0066] It should be noted that updating the hydraulic support's operating nodes based on the first and second state information involves first obtaining the current state information of the operating node, then determining the actual state information of the hydraulic support based on the first and second state information, and finally updating the operating node based on the actual state information and the current state information. In this way, by comprehensively analyzing the first and second state information, the current true state of the hydraulic support can be determined, including whether there are data errors, whether the hydraulic support is working normally, and the current operating information of the hydraulic support. Figure 6The flowchart shown illustrates the operation nodes for updating the hydraulic support. After determining the current real-time state information based on the first and second state information, it can be based on... Figure 6 The node flowchart shown analyzes and categorizes the data from the next measurement to achieve more accurate state analysis and data classification storage for the hydraulic support, providing a foundation for subsequent overall data analysis. For example, if the current state is determined to be the end of support relocation based on the current data, after obtaining new real-time column pressure and real-time stroke values, it can be determined whether the new real-time column pressure and real-time stroke values ​​indicate a pushing state. If so, the previous state node is deleted, and the hydraulic support's operation node is updated to the pushing state. If not, it is determined whether support relocation should begin. If so, the hydraulic support's operation node is updated to the relocation state.
