Description

Technical Field

[0001] This invention relates to the field of couplers, and more particularly to a coupler hydraulic control method, system, and terminal. Background Technology

[0002] A coupler is a device used to connect or match different components or systems, enabling them to efficiently transmit, convert, or coordinate energy, signals, etc.

[0003] Couplers include hydraulic couplers, which primarily use liquid as the working medium to transmit torque through the kinetic energy of the liquid. If the pipes on the coupler are damaged, liquid leakage will occur, affecting the normal operation of the coupler. Damage detection of the pipes on the coupler is typically performed by checking the pressure value inside the coupler.

[0004] The pressure inside the coupler can change due to pipe damage, so relying solely on the pressure inside the coupler for damage detection is not accurate enough and reduces the efficiency of subsequent repairs, which needs to be improved. Summary of the Invention

[0005] To improve repair efficiency, this invention provides a coupler hydraulic control method, system, and terminal.

[0006] In a first aspect, the present invention provides a hydraulic control method for a coupler, employing the following technical solution:

[0007] A coupler hydraulic control method, comprising:

[0008] Obtain the internal pressure value of the coupler;

[0009] When the internal pressure value is lower than the preset reference pressure value, the difference between the internal pressure value and the reference pressure value is calculated as the pressure difference value.

[0010] When the pressure difference exceeds a preset baseline difference value, the duration of pressure change is obtained;

[0011] The cause of pressure anomaly is matched against a preset pressure database based on the duration of pressure changes.

[0012] When the cause of the pressure anomaly is a preset liquid leakage anomaly, a preset leak detection method is used to detect the leak and determine the leakage area.

[0013] Based on the leak area, a preset repair device is used to repair the leak using a preset repair method.

[0014] By adopting the above technical solution, the internal pressure value of the coupler is first obtained. When the internal pressure value is lower than the reference pressure value, the pressure difference between the two values ​​is calculated. If the pressure difference exceeds the reference difference, the duration of the pressure change is obtained, and the cause of the pressure anomaly is matched against the pressure database based on the duration of the pressure change. If the cause of the anomaly is a liquid leak, a leak detection method is used to determine the leak area, and then the repair device is controlled to repair the leak according to the repair method, thereby improving the repair efficiency.

[0015] Optional leak detection methods include:

[0016] When the cause of the pressure anomaly is a preset liquid leakage anomaly, the preset opening and closing valves are controlled to open and close sequentially in a preset valve opening and closing sequence, and the closing pressure value is obtained during the valve closing period.

[0017] The opening and closing detection duration is obtained when the closing pressure value and the internal pressure value are inconsistent.

[0018] The abnormal valve number is determined based on the opening and closing detection time, the valve opening and closing sequence, and the preset baseline detection time.

[0019] The location of the abnormal valve is matched from a preset number database based on the abnormal valve number;

[0020] Determine the leakage area based on the location of the abnormal valve;

[0021] Based on the leak area, a repair device is used to repair the leak using a repair method.

[0022] Optional repair methods include:

[0023] Obtain regional image information of the leak area;

[0024] The location and size of the leak are determined based on regional image information, pre-defined leak characteristics, and reference objects.

[0025] The amount and shape of the repair material are matched from a preset repair database based on the location and dimensions.

[0026] Based on the shape of the repair material, a preset trimming device is used to modify the shape of the preset repair material.

[0027] After the trimming is completed, the repair device controls the amount of repair material used to seal the leak location. After the sealing is completed, the preset lighting device is controlled to illuminate the leak location with a preset light intensity value and the lighting duration is obtained.

[0028] The baseline illumination duration is determined based on the amount and shape of the repair material, as well as the light intensity value.

[0029] When the illumination duration matches the reference illumination duration, the illumination device is controlled to stop illuminating in order to complete the leak repair.

[0030] Optional, pressure anomaly detection methods may also be included:

[0031] When the abnormal pressure is not caused by a preset liquid leakage, the control coupler is paused, and after a preset pause time, the swing amplitude value of the detection ball inside the coupler is obtained.

[0032] When the swing amplitude value does not fall within the preset reference swing range, the difference between the swing amplitude value and the minimum value of the reference swing range is calculated as the swing difference value.

[0033] The viscosity value of the liquid is matched from a preset viscosity database based on the swing difference value;

[0034] When the liquid viscosity value exceeds the preset baseline viscosity value, a liquid viscosity warning will be reported.

[0035] Optionally, a leak detection method may also be included:

[0036] When the liquid viscosity value exceeds the preset reference viscosity value, a reference swing difference value is determined based on the liquid viscosity value.

[0037] When the swing difference value is inconsistent with the reference swing difference value, the position information of the detection ball is obtained.

[0038] The abnormal detection ball number is matched from the preset number database based on the detection ball's position information;

[0039] The abnormal amplitude area is determined based on the abnormal detection ball number;

[0040] Based on the abnormal amplitude area, the repair device is controlled to repair the area using the repair method.

[0041] Optionally, it also includes a step following the matching of anomaly detection ball numbers from a preset number database based on the detection ball's position information:

[0042] The installation duration is matched from a preset time database based on the anomaly detection ball number;

[0043] Determine the degree of dirt adhesion based on the installation duration;

[0044] The weight value affecting the dirt is determined based on the degree of dirt adhesion and the preset dirt weight value;

[0045] The actual weight value is determined based on the influencing weight value and the preset baseline weight value;

[0046] The reference swing range is corrected from the preset swing database based on the actual weight value, and the corrected reference swing range is defined as the swing difference range.

[0047] When the amplitude difference value does not fall within the swing difference range, the amplitude abnormality area is determined according to the abnormal detection ball number.

[0048] Based on the abnormal amplitude area, the repair device is controlled to repair the area using the repair method.

[0049] Optional, rinsing methods are also included:

[0050] When the internal light transmittance is lower than the preset benchmark light transmittance, the pipe material information of the coupler is obtained;

[0051] The flushing fluid is determined based on the pipe material information;

[0052] The flushing intensity and baseline flushing duration are matched from a preset flushing database based on the internal light transmittance value.

[0053] Based on the flushing liquid, a preset flushing device is controlled to flush the pipeline with a flushing force value. During flushing, the flushing duration is obtained, and the detection ball is controlled to perform self-cleaning using a preset self-cleaning method.

[0054] When the flushing time is consistent with the reference flushing time, the flushing device is controlled to stop flushing, and the preset drying device is controlled to dry the pipeline.

[0055] After the pipeline is dried, the preset replenishment device is controlled to replenish the liquid.

[0056] Optional self-cleaning methods include:

[0057] The flushing device acquires the weight distribution information of the detection ball during pipeline flushing.

[0058] Determine the distribution of dirt based on weight distribution information;

[0059] The rotation cleaning parameters are determined based on the distribution of dirt and the preset rinsing direction.

[0060] The detection ball is controlled to rotate and clean based on the rotation cleaning parameters, and the weight distribution information is updated.

[0061] When the updated weight distribution information is consistent with the preset uniform distribution information, the rotation speed is determined based on the updated weight distribution information, the position information of the detection ball, and the flushing force value, and the rotation speed is used to control the detection ball to rotate.

[0062] Secondly, this application provides a coupler hydraulic control system, which adopts the following technical solution:

[0063] A coupler hydraulic control system, comprising:

[0064] The acquisition module is used to acquire internal pressure value, pressure change duration, closing pressure value, opening and closing detection duration, area image information, illumination duration, contraction image information, lighting image information, swing amplitude value, detection ball position information, pipe material information, flushing duration, and weight distribution information.

[0065] A memory for storing the program of any of the above-mentioned coupler hydraulic control methods;

[0066] A processor is used to load, execute, and implement programs stored in memory.

[0067] Thirdly, this application provides a smart terminal, which adopts the following technical solution:

[0068] A smart terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and executed any of the above-mentioned coupler hydraulic control methods.

[0069] In summary, this application includes at least one of the following beneficial technical effects:

[0070] 1. First, obtain the internal pressure value of the coupler. When the internal pressure value is lower than the reference pressure value, calculate the pressure difference between the two values. If the pressure difference exceeds the reference difference, obtain the pressure change duration and match the cause of the pressure anomaly from the pressure database based on the pressure change duration. If the cause of the anomaly is a liquid leak, use a leak detection method to determine the leak area, and then control the repair device to repair the leak according to the repair method, thereby improving repair efficiency.

[0071] 2. When the abnormal pressure is not caused by a liquid leak, first stop the coupler from operating. After the stoppage period, obtain the swing amplitude value of the detection ball inside the coupler. If this swing amplitude value is not within the reference swing range, calculate the difference between it and the minimum value of the reference swing range, i.e., the swing difference value. Match the liquid viscosity value from the viscosity database based on the swing difference value. Once the liquid viscosity value exceeds the reference viscosity value, report a liquid viscosity warning to ensure the stable operation and working efficiency of the coupler.

[0072] 3. By linking the number of the detection ball to the installation time, and considering the impact of factors such as dirt on the oscillation, the oscillation judgment criteria are continuously revised, and abnormal areas are repaired. This ensures that the detection and handling of abnormalities in the coupler are more accurate and detailed, guaranteeing the normal operation and stable performance of the coupler.

[0081] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0082] This application discloses a coupler hydraulic control method.

[0083] Reference Figure 1 A coupler hydraulic control method includes the following steps:

[0084] Step 100: Obtain the internal pressure value of the coupler.

[0085] The internal pressure value refers to the pressure inside the coupler's pipes. The internal pressure value is obtained by measuring a pressure sensor.

[0086] Step 101: When the internal pressure value is lower than the preset reference pressure value, calculate the difference between the internal pressure value and the reference pressure value as the pressure difference value.

[0087] The reference pressure value refers to the minimum pressure that the coupler's internal piping should reach. This reference pressure value is predetermined by those skilled in the art and will not be elaborated upon here. The pressure difference value refers to the difference in pressure values ​​within the piping when abnormalities occur. The pressure difference value can be obtained by calculating the difference between the internal pressure value and the reference pressure value.

[0088] When the internal pressure value is lower than the reference pressure value, it indicates that the pressure value inside the pipeline is abnormal. The pressure difference value needs to be calculated for subsequent steps.

[0089] Step 102: When the pressure difference value exceeds the preset benchmark difference value, obtain the pressure change duration.

[0090] The baseline difference value is a value used to help determine whether the pressure difference inside the pipeline is too large. The baseline difference value is preset by those skilled in the art and will not be elaborated upon here. The pressure change duration refers to the time it takes for the pressure inside the pipeline to decrease from the baseline pressure value to the internal pressure value. The pressure change duration is obtained through a preset electronic timer. When the internal pressure value is lower than the baseline pressure value, the electronic timer starts timing until the pressure difference value exceeds the baseline difference value, at which point the electronic timer stops timing and outputs the pressure change duration.

[0091] When the pressure difference exceeds the baseline difference, it indicates that the pressure difference inside the pipeline is too large, and the duration of the pressure change needs to be obtained for subsequent steps.

[0092] Step 103: Match the cause of pressure abnormality from the preset pressure database based on the duration of pressure change.

[0093] An abnormal pressure condition refers to any factor that causes abnormal pressure within a pipeline. This includes abnormal liquid leakage. An abnormal liquid leakage occurs when a rupture occurs at a point in the pipeline, leading to liquid leakage and consequently, abnormal internal pressure. The causes of abnormal liquid leakage are pre-defined by those skilled in the art and will not be elaborated upon here.

[0094] The pressure database can be used to match the causes of pressure anomalies with the duration of pressure changes. It contains the correspondence between the duration of pressure changes and the causes of pressure anomalies. The pressure database is a manually set database, which will not be elaborated on here.

[0095] If the pressure change takes 1 second, it indicates that the pressure inside the pipeline is abnormally high, and the cause of the pressure abnormality can be matched using a pressure database.

[0096] Step 104: When the cause of the pressure anomaly is a preset liquid leakage anomaly, perform leak detection using a preset leak detection method to determine the leakage area.

[0097] Leak detection methods refer to methods for detecting the location of damage in a broken pipe. These methods are explained in detail in subsequent steps 200 to 205 and will not be repeated here. The leak area refers to the region in the pipe where the damage has caused liquid leakage. Leak detection methods can determine the leak area; the specific methods for determining this area are explained in detail in subsequent steps 200 to 205 and will not be repeated here.

[0098] Based on the above explanation, if the pressure change lasts for 1 second, it indicates that the pressure anomaly inside the pipeline is occurring very rapidly, suggesting that the cause is a liquid leak. When the cause of the pressure anomaly is a liquid leak, it indicates a rupture in the pipeline. A pre-set detection device needs to be used to detect the leak and pinpoint the location of the leak for subsequent steps. The detection device refers to the device used to detect leaks in the pipeline.

[0099] Step 105: Based on the leak area, control the preset repair device to repair the leak using the preset repair method.

[0100] A repair device refers to a device used to repair leaks in a leaking area. A repair method refers to a method used to repair leaks in a leaking area. Specific repair methods are described in detail in subsequent steps 300 to 306, and will not be repeated here. The repair device is controlled to repair the leak in the leaking area using the repair method for subsequent use.

[0101] Reference Figure 2 The leak detection method includes the following steps:

[0102] Step 200: When the cause of the pressure anomaly is a preset liquid leakage anomaly, control the preset opening and closing valves to open and close sequentially in a preset valve opening and closing sequence, and obtain the closing pressure value during the valve closing period.

[0103] An on / off valve is a valve used to control the flow of liquid within a pipeline. The valve opening / closing sequence refers to the order in which the valves are opened or closed in a pipeline system containing multiple valves. In this embodiment, multiple on / off valves are evenly arranged within the pipeline of the coupler. The closing pressure value refers to the pressure value inside the pipeline after the on / off valve is closed. The closing pressure value is obtained by measuring a pressure sensor.

[0104] When the abnormal pressure is caused by abnormal liquid leakage, the valves should be controlled to open and close in sequence according to the valve opening and closing order. Each time a valve is closed, the closing pressure value should be obtained for subsequent steps.

[0105] Step 201: Obtain the opening and closing detection time when the closing pressure value and the internal pressure value are inconsistent.

[0106] The opening and closing detection time refers to the time taken to open and close the valve according to the valve opening and closing sequence. The opening and closing detection time is obtained through an electronic timer. When the valve is opened and closed sequentially, the electronic timer starts timing. When the closing pressure value is inconsistent with the internal pressure value, the electronic timer stops timing and outputs the opening and closing detection time.

[0107] When the closing pressure value is inconsistent with the internal pressure value, it indicates that the internal pressure value has changed when the current valve is closed. It is necessary to obtain the opening and closing detection time for subsequent steps.

[0108] When the closing pressure value is consistent with the internal pressure value, it indicates that there is still no change inside the pipeline. It is necessary to continue to control the opening and closing of the valves in sequence and continuously obtain the closing pressure value.

[0109] Example explanation: If there are 3 valves that can be opened and closed, and each valve has its own corresponding number, namely A, B, and C, when valve A is closed, the closing pressure value needs to be obtained once. If the currently obtained closing pressure value is consistent with the internal pressure value, valve A needs to be controlled to open again, and then valve B needs to be controlled to close, and the closing pressure value needs to be obtained again. This process continues until the closing pressure value is inconsistent with the internal pressure value, and the opening and closing detection time is obtained.

[0110] Step 202: Determine the abnormal valve number based on the opening and closing detection time, valve opening and closing sequence, and preset benchmark detection time.

[0111] The baseline testing time refers to the time used to test the opening and closing of a single valve. This baseline testing time is preset by those skilled in the art and will not be elaborated upon here. The abnormal valve number refers to the number of the valve that is closed when the closing pressure value is inconsistent with the internal pressure value. The number of valves that have undergone opening and closing testing can be determined by dividing the opening and closing testing time by the baseline testing time. If the quotient has a decimal, the integer part is taken directly. Finally, by comparing the number of valves that have undergone opening and closing testing with the valve opening and closing sequence, the abnormal valve number can be obtained.

[0112] Step 203: Match the location of the abnormal valve from the preset number database according to the abnormal valve number.

[0113] An abnormal valve position refers to the location of a closed valve when an abnormal internal pressure value occurs. An abnormal valve position can be matched to its corresponding abnormal valve number using a numbered database, which contains the correspondence between abnormal valve numbers and positions. This numbered database is manually configured and will not be elaborated upon here.

[0114] Step 204: Determine the leakage area based on the location of the abnormal valve.

[0115] A leak area refers to the region on a pipeline where a rupture has caused a liquid leak. A pre-defined area database can be used to match leak areas corresponding to abnormal valve locations. This database contains the correspondence between abnormal valve locations and leak area values. The area database is manually configured and will not be elaborated upon here.

[0116] Step 205: Based on the leak area, control the repair device and repair method to repair the leak.

[0117] The control and repair device repairs the leak in the leaking area using a repair method for future use.

[0118] Reference Figure 3 The repair method includes the following steps:

[0119] Step 300: Obtain regional image information of the leaked area.

[0120] Regional image information refers to images of the leaked area. Regional image information is acquired through camera photography.

[0121] Step 301: Determine the location and size of the leak based on the regional image information, preset leak features, and reference objects.

[0122] Leakage features refer to the characteristics of a liquid leak in a pipeline. Reference objects are items used to assist in measuring the actual location and size of various features in the image information. The size and location of the leakage features and reference objects are preset by those skilled in the art and will not be elaborated here. Leakage location refers to the specific location where the liquid leaks in the pipeline. Location size refers to the dimensions of the leak location. A preset leakage database can be used to match the area image information, leakage features, and reference objects with the corresponding leakage location and location size, which includes the correspondence between area image information, leakage features, reference objects, leakage location, and location size. The leakage database is a manually set database and will not be elaborated here.

[0123] Step 302: Match the amount and shape of the repair material from the preset repair database based on the location and size.

[0124] Repair material usage refers to the specific amount of repair material used to repair the leak. Repair material shape refers to the shape into which the repair material is cut to better seal the leak. Repair material refers to the material used to repair the leak. Specific repair materials are predetermined by those skilled in the art and will not be elaborated upon here. The repair database can match the repair material usage and shape corresponding to the location dimensions, containing the correspondence between location dimensions, repair material usage, and repair material shape. The repair database is a manually set database and will not be elaborated upon here.

[0125] Step 303: Based on the shape of the repair material, control the preset trimming device to modify the shape of the preset repair material.

[0126] A trimming device is a device used to trim repair material to a desired shape. The trimming device is controlled to trim the repair material to match its shape for subsequent steps.

[0127] Step 304: After the trimming is completed, the repair device controls the amount of repair material used to seal the leak location. After the sealing is completed, the preset lighting device is controlled to illuminate the leak location with a preset light intensity value and the lighting duration is obtained.

[0128] A light irradiation device is a device used to irradiate repair materials with light. The light intensity value refers to the intensity of the light irradiating the repair materials. The light intensity value is preset by those skilled in the art and will not be elaborated upon here. The irradiation duration refers to the duration for which the light irradiation device irradiates the repair materials at the leak location. The irradiation duration is determined by an electronic timer. The electronic timer starts timing when the light irradiation device irradiates the repair materials at the leak location.

[0129] After trimming, the repair device controls the amount of repair material used to seal the leak location. After sealing, the lighting device controls the light intensity value to illuminate the leak location to accelerate the curing of the repair material. Finally, the duration of light illumination is obtained for subsequent steps.

[0130] Step 305: Determine the baseline illumination duration based on the amount of repair material used, the shape of the repair material, and the light intensity value.

[0131] The baseline illumination duration refers to the required time for the illumination device to irradiate the repair material at the leak location. A preset illumination database can be used to match the amount and shape of the repair material, as well as the corresponding illumination duration based on the illumination intensity. This database includes the correspondence between the amount and shape of the repair material, the illumination intensity, and the baseline illumination duration. The illumination database is a manually configured database and will not be elaborated upon here.

[0132] Step 306: When the illumination duration is consistent with the reference illumination duration, control the illumination device to stop illuminating in order to complete the leak repair.

[0133] When the illumination duration matches the baseline illumination duration, it indicates that the illumination equipment has completed illuminating the repair material. Simply control the illumination equipment to stop illuminating to complete the leak repair.

[0134] Reference Figure 4 The pressure anomaly detection method includes the following steps:

[0135] Step 400: When the cause of the pressure anomaly is not the preset liquid leakage anomaly, control the coupler to stop running, and after a preset pause time, obtain the swing amplitude value of the detection ball preset inside the coupler.

[0136] The pause duration refers to the time after the coupler has stopped operating, during which the amplitude of the swing of the detection ball inside the coupler is used to determine whether it is abnormal. The pause duration is preset by those skilled in the art and will not be elaborated upon here. The detection ball is an object installed inside the coupler's pipe for further detection of the internal liquid conditions. The swing amplitude value refers to the amplitude of the detection ball's swing within the pipe. The swing amplitude value is measured using an accelerometer.

[0137] When the cause of the pressure abnormality is not a liquid leakage abnormality, in order to determine whether the liquid in the pipeline is viscous, it is necessary to first control the coupler to stop operating, and after the pause time, obtain the swing amplitude value of the detection ball preset inside the coupler for subsequent steps.

[0138] Step 401: When the swing amplitude value does not fall within the preset reference swing range, calculate the difference between the swing amplitude value and the minimum value of the reference swing range as the swing difference value.

[0139] The reference swing range refers to the range within which the swing amplitude should fall when the liquid in the pipeline is in a normal state. The reference swing range is predetermined by those skilled in the art and will not be elaborated upon here. The swing difference value refers to the difference between the actual swing amplitude and the normal amplitude value when the swing amplitude of the detection ball deviates from the normal range. The amplitude difference value can be obtained by calculating the difference between the swing amplitude value and the minimum value of the reference swing range.

[0140] When the swing amplitude value does not fall within the reference swing range, it indicates that the swing amplitude of the detection ball deviates from the normal range, and the swing difference value needs to be calculated for subsequent steps.

[0141] Step 402: Match the liquid viscosity value from the preset viscosity database based on the swing difference value.

[0142] Liquid viscosity value refers to the quantitative value corresponding to the viscosity of the liquid in the pipe. A viscosity database can be used to match the viscosity value corresponding to the oscillation difference value, containing the correspondence between the oscillation difference value and the liquid viscosity value. The viscosity database is a manually set database and will not be elaborated upon here.

[0143] Step 403: When the liquid viscosity value exceeds the preset benchmark viscosity value, report a liquid viscosity warning.

[0144] The baseline viscosity value refers to the maximum viscosity that a liquid in a pipe can reach when it becomes viscous. A liquid viscosity warning indicates when the liquid in the pipe is excessively viscous. Both the liquid viscosity warning and the baseline viscosity value are preset by those skilled in the art and will not be elaborated upon here.

[0145] When the viscosity value of a liquid exceeds the baseline viscosity value, it indicates that the liquid in the pipeline is too viscous, and a liquid viscosity warning should be reported.

[0146] Reference Figure 5 The leakage verification method includes the following steps:

[0147] Step 500: When the liquid viscosity value exceeds the preset reference viscosity value, determine the reference swing difference value based on the liquid viscosity value.

[0148] The baseline swing difference value refers to the difference between the actual swing amplitude of the detection ball and the minimum value of a predetermined baseline swing range, caused by changes in the viscosity of the liquid within the pipe, when measuring the swing amplitude of the detection ball. A preset swing database can be used to match the baseline swing difference value corresponding to the liquid viscosity value. This database contains the correspondence between the liquid viscosity value and the baseline swing difference value. The swing database is a manually set database and will not be elaborated upon here.

[0149] When the viscosity value of the liquid exceeds the reference viscosity value, the reference swing difference value must be matched first for subsequent steps.

[0150] Step 501: When the swing difference value is inconsistent with the reference swing difference value, obtain the detection ball position information.

[0151] The detection ball position information refers to the location of the detection ball where the swing amplitude value is abnormal. This position information is obtained through a GPS positioning chip installed on the detection ball. When the amplitude difference value is inconsistent with the baseline swing difference value, it indicates an anomaly in the area where the detection ball is located, and the detection ball's position information needs to be obtained for subsequent steps.

[0152] Step 502: Match the abnormal detection ball number from the preset number database based on the detection ball position information.

[0153] Anomaly detection ball number refers to the number of the detection ball placed within an area where an anomaly exists. The anomaly detection ball number corresponding to the detection ball's location information can be matched using a number database. This database contains the correspondence between the detection ball's location information and its anomaly detection ball number. The number database is a manually set database and will not be elaborated upon here.

[0154] Step 503: Determine the amplitude anomaly area based on the anomaly detection ball number.

[0155] An anomalous amplitude region refers to the area where the detection ball exhibits an abnormal swing amplitude value. A preset anomaly database can be used to match the anomalous detection ball number with the corresponding anomalous amplitude region, containing the correspondence between the anomalous detection ball number and the anomalous amplitude region. This anomaly database is manually configured and will not be elaborated upon here.

[0156] Example explanation: If the anomaly detection ball is numbered A, then the corresponding amplitude anomaly region is region a. If the anomaly detection ball is numbered B, then the corresponding amplitude anomaly region is region b.

[0157] Step 504: Based on the abnormal amplitude area, control the repair device to perform area repair using the repair method.

[0158] The control and repair device performs regional repairs on areas with abnormal amplitude using repair methods.

[0159] Reference Figure 6 It also includes the step following the matching of anomaly detection ball numbers from a preset number database based on the detection ball's position information:

[0160] Step 600: Match the installation duration from the preset time database based on the anomaly detection ball number.

[0161] Installation time refers to the duration of time the detection ball is installed inside the pipe. The installation time corresponding to the anomaly detection ball number can be matched using a time database, which contains the correspondence between the anomaly detection ball number and the installation time. This time database is a manually set database and will not be elaborated upon here.

[0162] Step 601: Determine the degree of dirt adhesion based on the installation duration.

[0163] Fouling adhesion refers to the degree of fouling that adheres to the outer surface of the test sphere due to the liquid inside the tube. A pre-set fouling database can be used to match the fouling adhesion level to the installation duration, showing the correlation between installation duration and fouling adhesion level. This fouling database is manually configured and will not be elaborated upon here.

[0164] Step 602: Determine the influencing weight value based on the dirt adhesion and the preset dirt weight value.

[0165] The dirt weight value refers to the weight of dirt per unit volume. This dirt weight value is predetermined by those skilled in the art and will not be elaborated upon here. The impact weight value refers to the excess or deviation of the test ball's weight from its initial standard weight or normal operating weight range caused by dirt adhesion. The impact weight value can be obtained by calculating the product of the dirt adhesion degree and the dirt weight value.

[0166] Step 603: Determine the actual weight value based on the influencing weight value and the preset baseline weight value.

[0167] The baseline weight value refers to the weight of the test ball itself. This baseline weight value is predetermined by those skilled in the art and will not be elaborated upon here. The actual weight value refers to the weight of the test ball after it has been covered with dirt. The actual weight value can be obtained by calculating the sum of the factors affecting the actual weight value and the baseline weight value.

[0168] Step 604: Correct the reference swing range from the preset swing database based on the actual weight value, and define the corrected reference swing range as the swing difference range.

[0169] The correction of the baseline swing range refers to the need to adjust the baseline swing range when the weight of the ball varies, as this will result in differences in the swing amplitude. The swing difference range is the corrected baseline swing range. A swing database can be used to correct the baseline swing range corresponding to the actual weight value; it contains the correspondence between the actual weight value and the corrected baseline swing range. The swing database is a manually set database and will not be elaborated upon here.

[0170] Step 605: When the amplitude difference value does not fall within the swing difference range, determine the amplitude abnormality area based on the abnormal detection ball number.

[0171] An anomalous amplitude region refers to the area where a detection ball exhibits an abnormal swing amplitude value. An anomalous amplitude region can be matched to the anomalous detection ball number using an anomaly database; this database contains the correspondence between the anomalous detection ball number and the anomalous amplitude region. When the amplitude difference value does not fall within the swing difference range, it indicates an anomaly in the region where the detection ball is located, and the anomalous amplitude region needs to be matched for subsequent steps.

[0172] Step 606: Based on the abnormal amplitude area, control the repair device to perform area repair using the repair method.

[0173] The control and repair device performs regional repairs on areas with abnormal amplitude using repair methods.

[0174] Reference Figure 7 The rinsing method includes the following steps:

[0175] Step 700: When the internal light transmittance is lower than the preset benchmark light transmittance, obtain the pipe material information of the coupler.

[0176] Pipe material information refers to the specific material used for the pipes on the coupler. This pipe material information can be obtained by scanning the barcode on the coupler using a pre-set barcode scanner. The information obtained after scanning the barcode corresponds to the pipe material information.

[0177] When the internal light transmittance is lower than the reference light transmittance, it is necessary to obtain the pipe material information of the coupler for subsequent steps.

[0178] Step 701: Determine the flushing liquid based on the pipe material information.

[0179] Flushing fluid refers to the liquid used to flush pipelines. A pre-set flushing database can be used to match the flushing fluid to the pipeline material information. This database contains the correspondence between pipeline material information and flushing fluids. The flushing database is a manually set database and will not be elaborated upon here.

[0180] Step 702: Match the flushing force value and the baseline flushing time from the preset flushing database based on the internal light transmittance value.

[0181] Flushing force value refers to the force required to flush the pipeline. Reference flushing duration refers to the duration required to flush the pipeline. The flushing database can match the internal light transmittance value with the corresponding flushing force value and reference flushing duration, which includes the correspondence between internal light transmittance value, flushing force value, and reference flushing duration.

[0182] Step 703: Based on the flushing liquid, control the preset flushing device to flush the pipeline with a flushing force value. When flushing, obtain the flushing duration and control the detection ball to perform self-cleaning with a preset self-cleaning method.

[0183] A flushing device is a device used to flush the inside of a pipe. The flushing duration refers to the time the flushing device spends flushing the inside of the pipe. The flushing duration is obtained through an electronic timer. The electronic timer starts counting when the flushing device begins flushing. The self-cleaning method refers to the method by which the detection ball self-cleans the dirt attached to its outer surface. The specific self-cleaning method is explained in detail in subsequent steps 800 to 804, and will not be repeated here.

[0184] The flushing device is controlled to deliver flushing liquid into the pipeline at a flushing force value to flush the pipeline. During flushing, the flushing duration is obtained, and the detection ball is controlled to perform self-cleaning using a self-cleaning method.

[0185] Step 704: When the flushing time is consistent with the reference flushing time, control the flushing device to stop flushing and control the preset drying device to dry the pipeline.

[0186] A drying device is a device used to dry pipes after rinsing. When the rinsing time matches the reference rinsing time, it indicates that rinsing is complete. The rinsing device is then controlled to stop rinsing, and after rinsing stops, the drying device is controlled to dry the pipes for subsequent steps.

[0187] Step 705: After the pipeline drying is completed, control the preset replenishment device to replenish the liquid.

[0188] A replenishment device is a device used to replenish liquid in a dried pipeline. After the pipeline is dried, the replenishment device is controlled to replenish the liquid in the pipeline.

[0189] Reference Figure 8 The self-cleaning method includes the following steps:

[0190] Step 800: Obtain the weight distribution information of the detection ball based on the flushing device during pipeline flushing.

[0191] Weight distribution information refers to the distribution of the weight of the detection ball across its various parts or different locations. This weight distribution information is obtained through pressure sensors. In this embodiment, multiple pressure sensors are evenly distributed across the detection ball. By integrating the pressure data from all the sensors, the weight distribution information can be derived.

[0192] Step 801: Determine the dirt distribution based on the weight distribution information.

[0193] The dirt distribution refers to the distribution of dirt adhering to various parts of the detection ball. A preset distribution database can be used to match the dirt distribution information with the weight distribution information, containing the correspondence between weight distribution information and dirt distribution. This distribution database is manually set and will not be elaborated upon here.

[0194] Step 802: Determine the rotation cleaning parameters based on the distribution of dirt and the preset rinsing direction.

[0195] The flushing direction refers to the direction in which the flushing device flushes the pipeline. The flushing direction is preset by those skilled in the art and will not be elaborated upon here. The rotational cleaning parameter refers to the angle at which the detection ball rotates as the flushing time changes. To better remove dirt from the detection ball, the dirt must first be evenly distributed on the ball; therefore, the detection ball must always be tangent to the flushing direction, requiring a certain angle of rotation. The flushing database can be used to match the dirt distribution with the corresponding flushing direction, containing the correspondence between dirt distribution, flushing direction, and rotational cleaning parameters.

[0196] Step 803: Control the detection ball to perform rotation cleaning based on the rotation cleaning parameters, and update the weight distribution information.

[0197] The detection ball is controlled to rotate and clean using rotational cleaning parameters, and the weight distribution information is acquired again to update the weight distribution information for subsequent steps.

[0198] Step 804: When the updated weight distribution information is consistent with the preset uniform distribution information, determine the rotation speed according to the updated weight distribution information, the detection ball position information and the flushing force value, and control the detection ball to rotate based on the rotation speed.

[0199] Uniform distribution information refers to the state where the weight is consistent across all parts of the detection ball. This uniform distribution information is preset by those skilled in the art and will not be elaborated upon here. Rotation speed refers to the speed at which the detection ball rotates around its own axis to achieve optimal descaling. A preset rotation database can be used to match updated weight distribution information, detection ball position information, and the rotation speed corresponding to the flushing force value. This database includes the correspondence between the updated weight distribution information, detection ball position information, flushing force value, and rotation speed. This rotation database is a manually set database and will not be elaborated upon here.

[0200] When the updated weight distribution information is consistent with the uniform distribution information, it means that the weight on all parts of the detection ball is consistent. The rotation speed needs to be matched first, and then the detection ball needs to be controlled to rotate at the rotation speed to achieve a better descaling effect and thus complete the descaling.
