Description

Technical Field

[0001] The present disclosure belongs to the field of leakage monitoring, and more specifically, relates to a hydraulic oil leakage monitoring method and device, electronic equipment, and storage medium. Background Art

[0002] In industrial production, numerous devices rely on hydraulic systems to power complex operations, such as rotary kilns in the building materials industry, rolling mills in the metallurgical industry, and excavators in construction machinery. Hydraulic oil, the key medium for transmitting energy in hydraulic systems, ensures stable operation, directly impacting the normal operation and production efficiency of the entire equipment.

[0003] However, hydraulic oil leakage has always been a major challenge plaguing the reliability and safety of hydraulic systems. Traditional methods for monitoring hydraulic oil leaks are often simple and crude, typically relying solely on regular manual inspections of the equipment's exterior to check for obvious oil dripping, or installing simple pressure switches in the hydraulic system that sound an alarm when the pressure falls below a preset value, indicating a possible leak. However, these methods have many limitations. Limited by manpower and time, manual inspections cannot achieve real-time, continuous monitoring, making it difficult to detect even the smallest leaks in the early stages. By the time signs of a leak become visible to the naked eye, the leak is often already quite severe, potentially causing some damage to the equipment, such as increased wear on hydraulic components and decreased equipment accuracy.

[0004] Therefore, an accurate and reliable method for monitoring hydraulic oil leakage is needed. Summary of the Invention

DETAILED DESCRIPTION

[0013] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present disclosure. However, it will be apparent to those skilled in the art that the present disclosure may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present disclosure with unnecessary detail.

[0014] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, specific embodiments will be described below with reference to the accompanying drawings.

[0015] Please refer to Figure 1 , Figure 1 A flow chart of a hydraulic oil leakage monitoring method provided in one embodiment of the present disclosure, the method comprising: S101: determining a target monitoring strategy from a plurality of standard monitoring strategies based on an operation type and operation accuracy of a target device, and determining a target monitoring indicator from a plurality of standard monitoring indicators based on an operation type and operation accuracy of a target device.

[0016] In this embodiment, the target equipment is equipment that relies on hydraulic oil to power its operations and complete specific tasks. The normal operation of these devices depends on the stable operation of the hydraulic system. For example, a rotary kiln is a large-scale industrial equipment used for calcining materials. The rotation, position adjustment, and material conveyance of the kiln are all driven by the hydraulic system.

[0017] Operation types refer to the different types of work tasks or operating modes performed by the target equipment. Different operation types have varying impacts on the hydraulic system and the working condition of the hydraulic oil, necessitating targeted monitoring. For rotary kilns, these types of operations include rotating the kiln body (causing the material to tumble and heat within the kiln), controlling kiln movement (ensuring stable movement within a certain range to prevent excessive wear), and assisting in material transportation (using hydraulic devices to propel the material forward within the kiln, ensuring smooth material handling).

[0018] Operational accuracy refers to the degree of precision or precision required by the target equipment when performing its task. For example, when rotating a rotary kiln, if it is simply to provide power, the operational accuracy is low. However, under different production process requirements, the rotary kiln requires different rotation speeds. The hydraulic station can precisely control the flow of hydraulic oil by adjusting the flow control valve in the hydraulic system, thereby achieving precise adjustment of the rotary kiln's speed. In this case, the operational accuracy is relatively high.

[0019] A standard monitoring strategy is a set of predefined, universal monitoring methods and rules, including the selection of monitoring equipment and the timing of monitoring. These standard monitoring strategies are based on a general understanding of various hydraulic systems and an analysis of common failure modes. For example, when controlling kiln movement, the hydraulic tumbler system controls kiln movement by adjusting the volume (fluid level) of the hydraulic oil. Even slight changes in the fluid level can directly affect the magnitude and direction of the thrust applied by the hydraulic tumbler to the kiln, thereby affecting the accuracy of kiln movement control. Pressure also plays a role in controlling kiln movement, as it correlates with the fluid level and jointly influences the performance of the hydraulic tumbler. Flow rate has a relatively small impact on kiln movement control. In this case, level and pressure monitoring devices can be selected as monitoring devices, while the flow rate monitoring device can be temporarily deactivated. Monitoring can be performed every five minutes.

[0020] A targeted monitoring strategy is a selection of standard monitoring strategies based on the specific operation type and accuracy of the target equipment, identifying the most appropriate monitoring strategy for the equipment's current operation. This personalized approach to standard monitoring strategies allows for more precise focus on the most critical monitoring points and moments during the equipment's actual operation, improving monitoring effectiveness and accuracy.

[0021] Standard monitoring indicators are pre-defined general monitoring parameters and parameter ranges, including specific monitoring equipment and the normal data value ranges corresponding to these equipment. These indicators are used to measure the performance of various parameters of hydraulic oil under normal operating conditions to determine whether any abnormalities have occurred. For example, the standard data range for liquid level sensors is specified as 30%-70% of the tank height (i.e., the liquid level is considered normal within this range), and the standard data range for pressure sensors is 8-12 MPa (indicating that the normal operating pressure should be within this range).

[0022] Target monitoring indicators are selected and adjusted from standard monitoring indicators based on the target equipment's operating type and accuracy, resulting in the most appropriate indicator for the equipment's actual operating needs. They better reflect the hydraulic oil's operating characteristics under specific operating conditions, more accurately reflecting whether the hydraulic oil is functioning properly or if there is a risk of leakage.

[0023] In this embodiment, a target monitoring strategy may be determined from a plurality of standard monitoring strategies according to the operation type and operation accuracy of the target device through a pre-set mapping table, and a target monitoring indicator may be determined from a plurality of standard monitoring indicators.

[0024] The mapping table can be as shown in Table 1: Table 1 Mapping table of operation type and accuracy, target monitoring strategy and target monitoring indicators

[0025] S102: Monitoring the hydraulic oil leakage state based on the target monitoring strategy to obtain first monitoring data.

[0026] In this embodiment, the target monitoring strategy is a monitoring strategy suitable for the current operation of the target device that is selected from multiple standard monitoring strategies based on the operation type and operation accuracy of the target device.

[0027] The first monitoring data is the hydraulic oil status data obtained through monitoring according to the target monitoring strategy. This data is the basic information for determining whether the hydraulic oil is leaking. It may include various parameters that can reflect the changes in the hydraulic oil working state, such as the rate of change of liquid level, pressure, and flow.

[0028] S103: Adjust the target monitoring index based on the temperature information of the hydraulic oil to obtain a first monitoring index.

[0029] In this embodiment, hydraulic oil temperature information refers to the significant impact of hydraulic oil temperature on its physical properties (such as viscosity and volume), which in turn affects the operating status and monitoring indicators of the hydraulic system. Considering that temperature changes can cause the volume of hydraulic oil to expand or contract, it also changes its viscosity, thereby affecting parameters such as pressure and fluid level. For example, as temperature rises, the viscosity of hydraulic oil decreases, improving its fluidity. This may reduce pressure loss and cause the fluid level to rise due to volume expansion.

[0030] The first monitoring indicator is the final monitoring indicator used to determine whether hydraulic oil is leaking, after adjusting the impact of hydraulic oil temperature on the target monitoring indicator. It more accurately reflects the normal state range of hydraulic oil under actual working conditions than the target monitoring indicator.

[0031] The temperature compensation for pressure can be determined by a first formula, which can be: ,in is the change in pressure loss due to viscosity change, is the length of the pipeline, is the flow rate in the pipe, is the pipe radius, is the dynamic viscosity at the current temperature, is the dynamic viscosity at the reference temperature and can be determined experimentally.

[0032] , is the correlation coefficient of the hydraulic oil characteristics and can be determined experimentally.

[0033] According to Darcy's law, for laminar flow in a circular duct, the pressure loss is , for example, at the reference temperature The pressure range is , the corresponding flow is , when the temperature becomes When the flow rate becomes , ,in is the coefficient of flow rate variation with temperature, which can be determined through experiments. The above parameters are dimensionless parameters, and the pressure range after adjustment is .

[0034] The temperature compensation for the liquid level can be determined according to the second formula, which can be: ,in is the change in liquid level height, is the volume at the current temperature, is the bottom area of ​​the hydraulic oil tank, ,in is the reference temperature The volume below, is the volume expansion coefficient of the hydraulic oil, which can be determined experimentally. , when the temperature becomes When the volume becomes .

[0035] For example, the temperature is When , the corresponding liquid level interval is , the above parameters are dimensionless parameters, and the adjusted liquid level range is .

[0036] S104: Determine whether the hydraulic oil is leaking based on the first monitoring data and the first monitoring indicator; wherein the target device is a device that requires hydraulic oil to supply power.

[0037] In this embodiment, the first monitoring data is a data set obtained by monitoring the hydraulic oil state using a previously determined target monitoring strategy, and can reflect the real-time changes in the hydraulic oil during equipment operation. The first monitoring data may include liquid level data, pressure data, flow data, liquid level change rate, pressure change rate, or flow change rate.

[0038] The first monitoring indicator is an indicator for judging whether the hydraulic oil is normal, which is obtained by adjusting the target monitoring indicator after comprehensively considering factors such as the operation type, operation accuracy and hydraulic oil temperature of the target equipment. The first monitoring indicator corresponds to the first monitoring data, that is, the data contained in the first monitoring data can all be found in the first monitoring indicator, because the first monitoring data is based on the target monitoring strategy to determine the leakage status of the hydraulic oil, and the first monitoring indicator is obtained after adjusting the target monitoring indicator based on the temperature, and the target monitoring strategy and the target monitoring indicator are both determined based on the operation type and operation accuracy of the target equipment. According to the above explanation, the target monitoring strategy and the target monitoring indicator are both determined through the same mapping table, so the amount of data in the first monitoring data corresponds one-to-one to the amount of data in the first monitoring indicator.

[0039] As can be seen from the above, the present disclosure selects the most appropriate monitoring strategy and monitoring indicators based on the target equipment's operating type and operating accuracy, ensuring accurate and targeted monitoring. Different equipment and operating environments have different monitoring requirements, which can optimize monitoring results and reduce the possibility of false alarms and missed alarms. Considering the impact of hydraulic oil temperature on leak monitoring, the present disclosure adjusts the target monitoring indicators to adapt to changes in hydraulic oil temperature, ensuring that the monitoring indicators maintain their effectiveness and accuracy under different temperature conditions, thereby improving the accuracy and reliability of hydraulic oil leak monitoring.

[0040] In one embodiment of the present disclosure, the standard monitoring strategy includes: standard monitoring equipment and standard monitoring time; Target monitoring strategy, including: target monitoring equipment and target monitoring time; Determine the target monitoring strategy from multiple standard monitoring strategies based on the target equipment's operation type and operation accuracy, including: determining a target monitoring device from a plurality of standard monitoring devices based on an operation type of the target device; Determining a target monitoring time from a plurality of standard monitoring times based on the operating accuracy of the target device; Determine the target monitoring strategy based on the target monitoring device and target monitoring time.

[0041] In this embodiment, standard monitoring equipment refers to different monitoring equipment corresponding to different actions of the target equipment. The monitoring equipment may include pressure monitoring equipment, liquid level monitoring equipment and flow monitoring equipment. Since different operations have different requirements or impacts on pressure, liquid level and flow, different monitoring equipment can be selected.

[0042] The standard monitoring time is the time set in the standard monitoring strategy for data collection. The setting of these time points or time intervals is based on the empirical summary of the equipment's operating patterns and the timing of common faults. The purpose is to obtain hydraulic oil parameters at critical times to promptly detect potential problems. For example, monitoring can be performed at time points such as equipment startup, 10 minutes after the equipment has been running, every hour of operation, 5 minutes after a load change, or periodic monitoring can be performed every 30 minutes. Alternatively, the hydraulic press can be monitored to determine the end of its operation. At this time, the hydraulic oil level can be monitored because all the hydraulic oil has returned to the hydraulic station. The hydraulic oil level monitored at this time is the most accurate. Whether the hydraulic press has completed its operation can be determined by monitoring the movement of the hydraulic press's mechanical arm. When the hydraulic press's mechanical arm is at its highest point, it can be determined that the operation has ended.

[0043] In this embodiment, the number of standard monitoring devices may be one or more. The standard monitoring devices referred to here may be regarded as a set containing at least one element. Each set of standard monitoring devices corresponds to a standard operation type. For the control of the rotary kiln, the operation types are limited. The standard monitoring devices corresponding to each operation type may be predetermined. When hydraulic oil is required to provide operation power, the operation type of the target operation may be matched with the above-mentioned predetermined operation type, and the standard monitoring devices corresponding to the same operation type may be used as target monitoring devices.

[0044] The following standards can be used to determine standard equipment: In response to the operation type of the target device satisfying the first operation condition, determining that the target monitoring device is a liquid level monitoring device; In response to the operation type of the target device satisfying a second operation condition, determining that the target monitoring device is a pressure monitoring device; In response to the operation type of the target device satisfying the third operation condition, the target monitoring device is determined to be a flow monitoring device.

[0045] In this embodiment, the liquid level monitoring device may be a liquid level sensor, the pressure monitoring device may be a pressure sensor, and the flow monitoring device may be a flow sensor or a flow monitor. The pressure monitoring device may be installed on the oil outlet and return lines, the liquid level monitoring device may be installed on the top of the hydraulic oil tank, and the flow monitoring device may be installed on the oil outlet and return lines.

[0046] The first operating condition may be a liquid level-related operating type. For operating types closely related to liquid level, such as controlling kiln body movement, the standard monitoring equipment is a liquid level sensor.

[0047] The second operating condition may be a pressure-related operating type. If the key parameter of the operating type is pressure, such as driving the kiln body to rotate, then the standard monitoring equipment is a pressure sensor.

[0048] The third operating condition can be a flow-related operation type. In auxiliary material conveying operations, since flow is a key parameter, a flow sensor is selected as the standard monitoring equipment.

[0049] The level-related operation type, the pressure-related operation type, and the flow-related operation type may be set empirically based on the type and operation characteristics of the target equipment.

[0050] In one embodiment of the present disclosure, the hydraulic oil leakage monitoring method further includes: Determine standard auxiliary monitoring equipment based on the operating accuracy of the target equipment.

[0051] Considering that when the operating accuracy of the target equipment is high, the monitoring dimension should be increased, that is, the types of monitoring equipment should be increased.

[0052] For example: in response to the operating accuracy of the target device being greater than or equal to a first accuracy threshold and less than a second accuracy threshold, one of the monitoring devices different from the standard monitoring device is used as the standard auxiliary monitoring device; In response to the operating accuracy of the target device being greater than a second accuracy threshold, all monitoring devices different from the standard monitoring device are used as standard auxiliary monitoring devices.

[0053] In this embodiment, the standard auxiliary monitoring equipment is essentially a monitoring equipment, which is an additional monitoring equipment based on the operation accuracy. The additional monitoring equipment and the original standard monitoring equipment can be used together as monitoring equipment to monitor the leakage of hydraulic oil.

[0054] As shown in Table 1, according to the type of operation, which is to push the kiln body to rotate, when the operation accuracy is low, the target monitoring equipment determined is the pressure monitoring equipment, and when the operation accuracy is high, the target monitoring equipment determined is the pressure monitoring equipment and the flow monitoring equipment, among which the flow monitoring equipment is the auxiliary monitoring equipment, that is, the additional monitoring equipment.

[0055] The operating accuracy of the target equipment can be quantified according to the operating accuracy requirements of the target equipment. For example, for the operation type of driving the kiln body to rotate, when only the power of rotation is provided, the corresponding operating accuracy can be 1. If it is precise speed regulation, under different production process requirements, the rotary kiln requires different rotation speeds, and the corresponding operating accuracy can be 2.

[0056] For example, in the operation of supporting and controlling the position of the kiln body, the kiln body's movement is controlled so that it can move up and down within a predetermined range. The operation accuracy can be 1. However, if the kiln body is to be kept balanced, a shift in its center of gravity or uneven external forces may cause the kiln body to become unbalanced. The hydraulic station can apply support forces to different parts of the kiln body through the coordinated operation of multiple hydraulic cylinders, maintaining the kiln body's balance and reducing vibration and shaking. In this case, the operation accuracy is relatively high, and the operation accuracy can be 2.

[0057] The operation accuracy can be determined according to a predetermined mapping table. Different operation accuracy requirements correspond to different operation accuracy. For the above operation accuracy, the first accuracy threshold may be 0.5, and the second accuracy threshold may be 1.5.

[0058] It should be noted that different operation accuracy judgment methods have corresponding first accuracy thresholds and second accuracy thresholds that are also different, that is, the first accuracy threshold and the second accuracy threshold can be determined according to actual conditions.

[0059] In this embodiment, considering that higher operating precision leads to more precise and frequent hydraulic oil movements, the internal seals may be more susceptible to damage due to frequent pressure changes and friction, leading to hydraulic oil leakage. Therefore, higher precision corresponds to more monitoring times, that is, the monitoring frequency should be increased.

[0060] Each standard monitoring moment corresponds to a standard operating accuracy. The degree of match between the target device's operating accuracy and the standard operating accuracy can be calculated through comparison or matching. The standard monitoring moment corresponding to the standard operating accuracy with the highest degree of match is used as the target monitoring moment. The degree of match can be calculated through a simple difference comparison, or, since the aforementioned operating accuracy can be quantified, the standard operating accuracy that matches the target device's operating accuracy can be used as the target operating accuracy, with the corresponding standard monitoring moment as the target monitoring moment.

[0061] The target monitoring time can be once every 10 minutes, or different monitoring frequencies can be set according to the stage of the operation, or monitoring can be performed at the end of one action of the hydraulic press. The standard monitoring time can be determined based on the characteristics and experience of the target equipment.

[0062] After determining the target monitoring device and the target monitoring time, they can be combined into a target monitoring strategy, and the leakage status of the hydraulic oil can be monitored according to the target monitoring strategy.

[0063] As can be seen from the above, this embodiment ensures targeted and effective monitoring by customizing the monitoring strategy based on the target equipment's operation type and operating accuracy, adapting to the needs of different equipment and operating environments. This embodiment considers the operation type and operating accuracy, allowing for flexible response to monitoring tasks with varying precision requirements, thereby improving monitoring flexibility and adaptability. By selecting appropriate monitoring equipment and determining appropriate monitoring times, this embodiment can accurately monitor hydraulic oil leakage, promptly identifying potential problems and improving the accuracy and reliability of hydraulic oil leakage monitoring.

[0064] In one embodiment of the present disclosure, the standard monitoring indicator includes: standard monitoring equipment and standard data interval; Target monitoring indicators, including: target monitoring equipment and target data interval; Target monitoring indicators are determined from multiple standard monitoring indicators based on the operation type and operation accuracy of the target equipment, including: determining a target monitoring device from a plurality of standard monitoring devices based on an operation type of the target device; Determining a target data interval from a plurality of standard data intervals based on an operation type and an operation accuracy of a target device; Determine the target monitoring indicators based on the target monitoring equipment and target data interval.

[0065] In this embodiment, the target monitoring device is determined using the same process as described above to ensure the same amount of data for subsequent comparisons. The target data interval is determined from multiple standard data intervals based on the target device's operating accuracy, and is suitable for the range of values ​​of hydraulic oil-related physical quantities required by the device under the specific operating accuracy requirements.

[0066] The higher the operating accuracy, the finer and more frequent the control of the hydraulic oil, the pressure, flow, etc. will be adjusted, and the more likely leakage will occur. Therefore, the higher the operating accuracy, the smaller the corresponding data range.

[0067] It should be noted that the target data interval includes: liquid level data interval, pressure data interval and / or flow data interval, that is, the target data interval and the target monitoring device should correspond.

[0068] Considering that different job types correspond to different data intervals, both the job type and job accuracy should be considered at the same time. The target data interval can be determined according to Table 1.

[0069] For example, when the operation type is to push the kiln body to rotate, according to Table 1, when the operation accuracy is low, the corresponding pressure data range is 8-12MPa, which can also be expressed as When the operating accuracy is high precision, the corresponding pressure data range is 9-11MPa, which is smaller than that of low precision.

[0070] From the above, it can be concluded that the present disclosure comprehensively considers the operation type and operation accuracy of the target equipment, accurately determines the target monitoring indicators from multiple standard monitoring indicators, ensures the pertinence and accuracy of monitoring, and can more effectively capture changes in the state of hydraulic oil. The determination of the target data interval not only takes into account the operation type, but also incorporates the operation accuracy, which helps to improve the sensitivity to changes in the state of hydraulic oil and promptly detect potential leakage problems. This embodiment avoids unnecessary monitoring equipment and data collection by accurately determining the target monitoring equipment and target data interval, thereby optimizing the monitoring process, improving monitoring efficiency, and enhancing the accuracy and reliability of hydraulic oil leakage monitoring.

[0071] In one embodiment of the present disclosure, the target monitoring device includes: a liquid level monitoring device, a pressure monitoring device, and a flow monitoring device; Target data interval, including: liquid level data interval, pressure data interval and / or flow data interval; Adjusting the target monitoring indicator based on the temperature information of the hydraulic oil to obtain a first monitoring indicator includes: In response to the target monitoring device including a liquid level monitoring device, adjusting the liquid level data interval based on the temperature information of the hydraulic oil to obtain a first monitoring indicator; In response to the target monitoring device including a pressure monitoring device, adjusting the pressure data interval based on the temperature information of the hydraulic oil to obtain a first monitoring indicator; In response to the target monitoring device including a liquid level monitoring device and the target monitoring device including a pressure monitoring device, the liquid level data interval and the pressure data interval are adjusted based on the temperature information of the hydraulic oil to obtain a first monitoring indicator.

[0072] In this embodiment, the liquid level monitoring device may be a liquid level sensor, the pressure monitoring device may be a pressure sensor, and the flow monitoring device may be a flow sensor. The target data interval refers to the data range interval corresponding to each monitoring device that is suitable for the current operation type and operation accuracy.

[0073] Hydraulic oil temperature information can be obtained through a temperature sensor. Given the impact of temperature on hydraulic oil viscosity, the viscosity of hydraulic oil (usually measured by dynamic viscosity) exhibits a complex pattern with temperature. Generally speaking, hydraulic oil viscosity decreases with increasing temperature. This is because as temperature rises, the intermolecular forces in the hydraulic oil weaken, increasing molecular motion, reducing internal friction and manifesting as a decrease in viscosity. According to Poiseuille's law in fluid mechanics, pressure differential is related to flow rate, pipe length, pipe radius, and fluid viscosity. The specific formula is shown above. In a hydraulic system, when flow rate, pipe length, and pipe radius remain unchanged, a decrease in hydraulic oil viscosity (due to increased temperature) results in a decrease in pressure differential. The effect of temperature on pressure can be compensated for using the first formula.

[0074] Considering the impact of temperature on the hydraulic oil volume, which causes changes in the fluid level, the second formula can be used to compensate for the temperature effect on the fluid level. Hydraulic oil expands with increasing temperature, a fundamental physical phenomenon of thermal expansion and contraction.

[0075] Since different monitoring devices are used for different operation types and operation precision, only when pressure monitoring devices and liquid level monitoring devices are included in the monitoring devices will the corresponding monitoring data intervals be adjusted and compensated. The adjusted data intervals and corresponding monitoring devices constitute the first monitoring indicator.

[0076] From the above, it can be concluded that the present disclosure can adjust the liquid level data interval and pressure data interval in the target monitoring indicator by considering the impact of hydraulic oil temperature on viscosity and volume, thereby obtaining a first monitoring indicator. This ensures the accuracy and reliability of the monitoring data and reduces false positives or omissions caused by temperature changes. This embodiment selects and adjusts the monitoring equipment and its corresponding data interval according to different operation types and operation accuracy. At the same time, when the monitoring equipment includes liquid level monitoring equipment and pressure monitoring equipment, temperature compensation can be performed on them in a targeted manner, so that the present disclosure can be widely applied to different types of hydraulic systems and operating environments.

[0077] In one embodiment of the present disclosure, determining whether hydraulic oil is leaking based on the first monitoring data and the first monitoring indicator includes: Obtain at least one monitoring result based on the first monitoring data and the first monitoring indicator; In response to the monitoring result being one, taking the monitoring result as a first monitoring result, and determining whether the hydraulic oil is leaking based on the first monitoring result; In response to there being multiple monitoring results, weighted calculation is performed on the multiple monitoring results to obtain a first monitoring result, and whether the hydraulic oil is leaking is determined based on the first monitoring result.

[0078] In one embodiment of the present disclosure, the monitoring results include: liquid level monitoring results, pressure monitoring results, and flow monitoring results; The hydraulic oil leakage monitoring method further includes: In response to the monitoring results including the liquid level monitoring result, the pressure monitoring result, and the flow monitoring result and the operation type of the target equipment meeting the first monitoring condition, the reference value of the liquid level monitoring weight is reduced based on the first liquid level step, the reference value of the pressure monitoring weight is increased based on the first pressure step, and the reference value of the flow monitoring weight is reduced based on the first flow step; In response to the monitoring results including the liquid level monitoring result, the pressure monitoring result, and the flow monitoring result and the operation type of the target equipment meeting the second monitoring condition, increasing the reference value of the liquid level monitoring weight based on the second liquid level step, decreasing the reference value of the pressure monitoring weight based on the second pressure step, and decreasing the reference value of the flow monitoring weight based on the second flow step; In response to the monitoring results including liquid level monitoring results, pressure monitoring results and flow monitoring results and the operation type of the target equipment meeting the third monitoring condition, the reference value of the liquid level monitoring weight is lowered based on the third liquid level step, the reference value of the pressure monitoring weight is lowered based on the third pressure step, and the reference value of the flow monitoring weight is increased based on the third flow step.

[0079] In this embodiment, the first monitoring data is obtained by monitoring the hydraulic oil status using the previously determined target monitoring strategy. This data reflects the real-time changes in the hydraulic oil during equipment operation and may include liquid level data, pressure data, and flow rate data. The first monitoring indicator may include liquid level data intervals, pressure data intervals, and flow rate data intervals. The monitoring result can be calculated by calculating the matching degree between the first monitoring data and the first monitoring indicator.

[0080] The matching degree can be calculated by the third formula, which can be: ,in, For matching, is the distance between the data and the center point, is the half width of the interval, with liquid level data and liquid level data interval For example, , the half-width of the interval .

[0081] The pressure matching degree and flow matching degree can be calculated respectively through the same calculation. When there is only one monitoring device, the corresponding monitoring result is one, which is also the monitoring result for judging whether the hydraulic oil is leaking, that is, the first monitoring result.

[0082] When there are multiple monitoring results, a first monitoring result can be obtained by weighted calculation, and the result after weighted calculation is used as the result for determining whether the hydraulic oil is leaking.

[0083] Considering that different target equipment operation types have different sensitivities to the hydraulic oil level, pressure, and flow rate. For example, in rotary kiln equipment whose operation type is to propel the kiln body into rotation, the pressure parameter is the key. Because stable pressure is the core factor to ensure the uniform rotation of the kiln body, changes in pressure may directly lead to unstable kiln rotation and affect the calcination effect of the material. Therefore, the system controls the pressure more frequently. At this time, pressure data is even more important for determining whether the hydraulic oil is leaking. In the operation of controlling the movement of the kiln body, the liquid level parameter may be more critical, because the change in liquid level is directly related to the control accuracy of the hydraulic wheel system on the movement of the kiln body. Therefore, the weight of liquid level monitoring can be appropriately increased at this time.

[0084] The first monitoring result may be compared with a predetermined threshold, for example: In response to a value of the first monitoring result being less than a first leakage threshold, determining that the hydraulic oil has leaked; In response to the value of the first monitoring result being greater than or equal to the first leakage threshold, it is determined that the hydraulic oil is not leaking.

[0085] The first leakage threshold may be determined experimentally.

[0086] The first monitoring condition may be a pressure-related operation type, the second monitoring condition may be a liquid level-related operation type, and the third monitoring condition may be a flow-related operation type.

[0087] The level-related operation type, the pressure-related operation type, and the flow-related operation type may be set empirically based on the type and operation characteristics of the target equipment.

[0088] The first liquid level step, the first pressure step, the first flow step, the second liquid level step, the second pressure step, the second flow step, the third liquid level step, the third pressure step and the third flow step can be determined based on experiments, but it should be noted that the sum of the first liquid level step and the first flow step is equal to the first pressure step, the sum of the second pressure step and the second flow step is equal to the second liquid level step, and the sum of the third liquid level step and the third pressure step is equal to the third flow step.

[0089] Consider that the state of equipment fluctuates during operation. For example, the sensitivity to various hydraulic oil parameters varies during the equipment's preparation phase, stable operation, and impending shutdown. The preparation phase places greater emphasis on pressure buildup, while the stable operation phase prioritizes fluid level and flow stability. A fixed step size would not be able to effectively adapt to these varying phases. Dynamically adjusting the step size allows for more precise adjustment of monitoring weights based on the equipment's current operating stage, enabling better identification of hydraulic oil leaks.

[0090] Therefore, the step size can be adjusted based on the target device's operating process. Specifically: In response to the target device being in a preparation phase, the first pressure step, the second pressure step, and the third pressure step are increased based on the first preparation step, the first liquid level step, the second liquid level step, and the third liquid level step are decreased based on the second preparation step, and the first flow rate step, the second flow rate step, and the third flow rate step are decreased based on the third preparation step; In response to the operating process of the target device being in the operating stage, the first pressure step, the second pressure step and the third pressure step are respectively reduced based on the first operating step, the first liquid level step, the second liquid level step and the third liquid level step are respectively increased based on the second operating step, and the first flow step, the second flow step and the third flow step are respectively increased based on the third operating step.

[0091] In this embodiment, it should be noted that the first preparation step is equal to the sum of the second preparation step and the third preparation step, the second operation step is equal to the sum of the first operation step and the third operation step, and the first preparation step, the second preparation step, the third preparation step, the first operation step, the second operation step and the third operation step can all be determined based on experience.

[0092] From the above, it can be concluded that the present disclosure can more comprehensively and accurately reflect the status of hydraulic oil by integrating multiple monitoring results such as liquid level, pressure and flow. The present disclosure can dynamically adjust the weights of liquid level, pressure and flow monitoring according to different operation types and equipment operation stages, so that monitoring is more in line with the actual operation needs of the equipment, thereby improving the effectiveness and accuracy of monitoring. Taking into account the different sensitivities to hydraulic oil parameters at different stages of equipment operation, this method can dynamically adjust the step size based on the equipment operation stage, thereby more accurately adjusting the monitoring weight. This monitoring strategy that matches the equipment operation status further improves the pertinence and accuracy of hydraulic oil leakage monitoring.

[0093] In one embodiment of the present disclosure, the first monitoring data includes: a liquid level change rate, a pressure change rate, and a flow rate change rate; The hydraulic oil leakage monitoring method further includes: Determining a standard liquid level change rate, a standard pressure change rate, and / or a standard flow rate change rate based on an operation type of the target equipment; In response to the fluid level change rate not matching the standard fluid level change rate and / or the pressure change rate not matching the standard pressure change rate and / or the flow change rate not matching the standard flow change rate, it is determined that the hydraulic oil is in a leakage state.

[0094] In this embodiment, taking into account the different operating characteristics of each operation type and its different demands for hydraulic oil, the liquid level change rate, pressure change rate and flow change rate corresponding to each operation type may be different. When it is found during the monitoring process that the monitored liquid level change rate does not match the standard liquid level change rate, or the pressure change rate does not match the standard pressure change rate, or the flow change rate does not match the standard flow change rate, it indicates that the hydraulic oil is leaking.

[0095] The standard liquid level change rate, standard pressure change rate and standard flow change rate corresponding to each operation type can be obtained based on historical records. It should be noted that the standard liquid level change rate, standard pressure change rate and standard flow change rate should all be within an interval range and include a margin to avoid false alarms.

[0096] The matching degree may be calculated based on whether the change rate is within the corresponding standard change rate interval. If so, the matching is achieved; otherwise, the matching is achieved.

[0097] From the above, it can be concluded that the present disclosure can detect changes in the hydraulic oil state by introducing the liquid level change rate, pressure change rate, and flow rate change rate as monitoring data. Compared to single liquid level, pressure, or flow rate data, change rate data can better reflect the dynamic characteristics of the hydraulic oil state, thereby improving the accuracy of hydraulic oil leakage monitoring. The present disclosure takes into account the different requirements of hydraulic oil for different operation types and can determine the corresponding standard liquid level change rate, standard pressure change rate, and / or standard flow rate change rate based on the operation type of the target equipment, making the monitoring more consistent with the actual needs of the equipment and enhancing the adaptability of the method.

[0098] Figure 2 This is a structural diagram of a hydraulic station hydraulic oil leakage rapid alarm and cut-off device provided by an embodiment of the present disclosure; Figure 2 A hydraulic station hydraulic oil leakage rapid alarm and cut-off device includes: a liquid level sensor, a pressure sensor, a first voltage comparator, a second voltage comparator, a first NAND gate, a second NAND gate, a transistor, a buzzer, a relay, a solenoid valve, a first sliding resistor, a second sliding resistor, multiple capacitors, multiple resistors, and multiple light-emitting diodes.

[0099] The inverting input terminal of the first voltage comparator is connected to the output terminal of the liquid level sensor, the non-inverting input terminal of the first voltage comparator is connected to the light emitting diode via the first sliding resistor, and the output terminal of the first voltage comparator is connected to the first input terminal of the first NAND gate; An inverting input terminal of the second voltage comparator is connected to an input terminal of the pressure sensor, a non-inverting input terminal of the second voltage comparator is connected to another light-emitting diode via a second sliding resistor, and an output terminal of the second voltage comparator is connected to a second input terminal of the first NAND gate; The output end of the first NAND gate is connected to the first input end and the second input end of the second NAND gate respectively, the output end of the second NAND gate is connected to the base of the transistor, the emitter of the transistor is used for grounding, the collector of the transistor is connected to the control end of the buzzer and the relay, and the pull-in end of the relay is connected to the solenoid valve.

[0100] Liquid level sensors are commonly used to monitor hydraulic oil leaks. They can be installed in a suitable location inside the hydraulic tank, such as the top. When the hydraulic oil level drops below a set threshold due to leakage, the sensor generates a signal.

[0101] Pressure sensors: To monitor pressure relief, pressure sensors are installed on key piping or components in the hydraulic system. During normal operation, the hydraulic system maintains a stable pressure range. If a pressure relief occurs and the pressure drops below a set value (e.g., 80% of the normal operating pressure), the pressure sensor detects the pressure change and issues a signal.

[0102] 2. Alarm part The signal from the sensor is transmitted to the alarm unit. The alarm unit can be a simple audible or visual alarm. When it receives an abnormal signal from the liquid level or pressure sensor, it will sound an audible or visual alarm.

[0103] 3. Cut off the part Solenoid reversing valve A solenoid reversing valve is installed in the main oil circuit of the hydraulic system. Upon receiving an abnormal signal from a sensor (processed by a controller), the solenoid reversing valve changes the position of the valve core, thereby cutting off the hydraulic oil supply path. This prevents further leakage of hydraulic oil and avoids the danger of continued system operation in a depressurized state. During normal operation, the solenoid reversing valve remains open, ensuring proper circulation of the hydraulic oil. In the event of a fault, the solenoid reversing valve is de-energized (normally closed), the valve core resets, and the oil circuit is cut off.

[0104] In this embodiment, a controller or a delay unit or other modules may be added to the circuit ( Figure 2(not shown) to implement a delayed alarm function. For example, the delay time of the controller or delay unit can be set so that when the liquid level sensor detects that the liquid level is below the normal lower limit for 30 consecutive seconds or the pressure sensor detects that the pressure drops by more than the set value within 10 seconds, a fault state is determined. The controller then issues a command to trigger the alarm part and control the operation of the shutdown part.
