Description

TECHNICAL FIELD

BACKGROUND

[0002] With the continuous growth of demand for electric power energy, as an important part of power grid regulation, the stable operation of the core equipment of the water pump water turbine unit is increasingly strict. The quality of lubricating oil directly relates to the service life and safety of key components such as unit bearings and speed regulation systems. According to statistics, equipment failures caused by oil pollution or degradation account for a considerable proportion of total failures, so real-time management and control of oil condition is a key link to ensure the safe production of power stations.

[0003] In the existing technical solutions, the oil online monitoring system and the purification system of large equipment (such as a water turbine unit) are usually independent physical systems. The online monitoring system is mainly responsible for real-time collection of various indicators of oil, and once an abnormal indicator is found, its main function is limited to sending an alarm signal to the central control room or the operation and maintenance personnel. The subsequent disposal process is heavily dependent on manual intervention, that is, the operation and maintenance personnel need to manually judge after receiving the alarm and manually start the corresponding device for processing. This oil management method has low automation and intelligence, and the operation and maintenance efficiency of the unit oil is very low. SUMMARY

In this application, by acquiring first and second indicator data representing different state dimensions in real time and comparing them with corresponding independent thresholds, the system achieves accurate quantification and hierarchical identification of oil contamination types. Based on this, the system can selectively activate the corresponding purification unit when a single indicator is abnormal, avoiding equipment damage caused by blindly starting purification equipment, according to the judgment results of the abnormal mode. Furthermore, for complex operating conditions with multiple indicators exhibiting concurrent abnormalities, by introducing equipment linkage priority rules and generating collaborative runtime sequences, the system effectively solves the problem of mutual interference caused by flow path conflicts resulting from the simultaneous operation of multiple devices, achieving improved operational efficiency for the monitored target oil while ensuring the safety of purification operations.

[0057] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0058] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various objects, but these objects are not limited by these terms. These terms are only used to distinguish the first object from the second object. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0059] The oil monitoring and purification linkage control method provided in this application can be applied to oil operation and maintenance systems for large industrial equipment. This system typically includes, but is not limited to, the target equipment under test (such as a water pump turbine unit), a monitoring terminal installed on the oil pipeline, a server with logical operation capabilities, and a purification module containing at least two sets of functionally independent purification units. The multi-dimensional monitoring terminal is communicatively connected to the server to collect and upload real-time index data (such as moisture and particulate matter) of the target oil under different state dimensions. The server is connected to both the monitoring terminal and the purification module, and has pre-set independent alarm thresholds for different indicators and equipment linkage priority rules. The purification module is connected in parallel or series with the main oil circuit through actuators such as solenoid valves, and its first purification unit (such as a vacuum dehydration device) and second purification unit (such as an electrostatic adsorption device) can independently start, stop, or operate collaboratively in response to control commands.

[0060] In one exemplary embodiment, such as Figure 1As shown, a method for oil monitoring, purification, and linkage control applied to water pumps and turbines is provided. Taking the application of this method to a server as an example, it includes the following steps S102 to S110. Wherein:

[0061] Step S102: Obtain real-time monitoring data for the target oil. The real-time monitoring data includes at least first indicator data and second indicator data characterizing different state dimensions of the target oil.

[0062] The target oil can be a liquid medium circulating inside large industrial equipment such as water pumps and turbines, such as lubricating oil, hydraulic oil, or insulating oil, used for lubrication, cooling, transmission, or insulation.

[0063] Real-time monitoring data can refer to a time-series data stream that reflects the physical or chemical properties of the target oil at the current moment. This data stream is usually generated by a sensor array deployed on the oil line, which is then converted into digital signals and transmitted.

[0064] The first and second indicator data can be parameter values ​​that characterize different dimensions of oil contamination. For example, the first indicator data can be a parameter characterizing the water content in the oil (such as water activity value or trace water value), and the second indicator data can be a parameter characterizing the degree of solid particle contamination in the oil (such as standard contamination level or the number of metal abrasive particles in a specific size range).

[0065] For example, the server can establish a connection with the front-end monitoring terminal via wired (such as Ethernet) or wireless communication. The server can actively poll or passively receive data packets uploaded by the monitoring terminal according to a preset sampling frequency (e.g., once per second or once per minute). The server parses the received packets and extracts the first indicator data corresponding to the moisture dimension and the second indicator data corresponding to the particle size dimension, respectively.

[0066] Step S104: Compare the first indicator data with a preset first threshold to obtain a first comparison result, and compare the second indicator data with a preset second threshold to obtain a second comparison result.

[0067] The first threshold and the second threshold can be numerical benchmarks or dynamic reference ranges pre-stored in the server configuration database. They are used as criteria to measure whether the target oil meets the safe operating conditions under the corresponding index dimensions. Their values ​​can be set based on industry standards (such as International Organization for Standardization standards) or the historical operating data of the equipment.

[0068] The first comparison result and the second comparison result can be logical state information that characterizes the relative quantitative relationship between real-time monitoring data and the corresponding threshold. For example, they can be Boolean values, state level codes (such as high, medium, low) or difference values.

[0069] For example, after obtaining the first indicator data (such as moisture content) and the second indicator data (such as the number of metal abrasive particles), the server can call the preset comparison logic in parallel or serially, respectively. The server compares the first indicator data with a preset first threshold. If the data value exceeds or deviates from the threshold range, a first comparison result representing "abnormality" is generated; otherwise, a first comparison result representing "normality" is generated. The server processes the second indicator data in the same way to obtain a second comparison result.

[0070] Optionally, when determining the comparison result, the server can also introduce a time window mechanism, that is, statistically analyze the distribution of comparison results within a preset time period, so as to determine the final comparison result based on the distribution of multiple comparison results in the current time window.

[0071] Step S106: In response to the first comparison result satisfying the abnormal condition corresponding to the first threshold, a first purification control command is generated.

[0072] The abnormal condition corresponding to the first threshold can be a pre-configured trigger rule used to define whether the first indicator data deviates from the safe range of normal oil operation. For example, when the comparison result shows that the real-time value is greater than or equal to the alarm threshold, it is considered to meet the abnormal condition.

[0073] The first purification control command is used to activate the first purification unit to perform a first type of purification treatment on the target oil.

[0074] The first purification unit can be a separate physical device specifically configured in the oil operation and maintenance system to remove first-class contaminants (such as moisture), such as a vacuum dehydration device or a centrifugal separation device.

[0075] After receiving the first comparison result, the server can continuously or periodically determine whether the result meets preset abnormal conditions. For example, when the first indicator is moisture content and the first comparison result indicates that the current moisture content is higher than a preset moisture content threshold, the server can determine that the abnormal condition is met and immediately trigger the instruction generation logic. The server can generate a first purification control instruction containing the target device address and action code according to a preset communication protocol. Subsequently, the server can send this instruction to the controller associated with the first purification unit via the control bus.

[0076] In some embodiments, the instructions generated by the server may also carry specific operating parameters (such as heating temperature setpoints) to control the first purification unit to operate under specific conditions.

[0077] Step S108: In response to the abnormal condition corresponding to the second threshold being met by the second comparison result, a second purification control command is generated.

[0078] The abnormal condition corresponding to the second threshold can be a pre-set logical judgment criterion in the server, used to identify whether the second indicator data exceeds the allowable pollution tolerance. For example, when the second comparison result represents a real-time particle count or pollution level higher than the preset safety level, it is considered to meet the condition.

[0079] The second purification control command is used to activate the second purification unit to perform a second type of purification treatment on the target oil. It may include a start trigger signal for the second purification unit, a power setting signal, and a switching signal for the associated flow path valve.

[0080] The second purification unit can be a functional module configured to remove second-class contaminants (such as solid particles and metal abrasive particles). It can work based on principles such as physical interception, electrostatic adsorption, or magnetic adsorption, such as an electrostatic adsorption oil filter or a high-precision mechanical filter.

[0081] In an exemplary embodiment, after the server confirms through comparison logic that the second comparison result meets the abnormal conditions (e.g., the pollution level is detected to have increased from level A to level B), it can locate the second purification unit responsible for handling particulate pollution based on the internal device mapping table.

[0082] The server can generate a second purification control command containing the target device address and action code according to a preset communication protocol. Subsequently, the server can send this command to the controller associated with the second purification unit via the control bus.

[0083] Optionally, the instructions generated by the server may also include the expected runtime or target purification level for the purification task, in order to achieve more intelligent task scheduling.

[0084] Step S110: In response to the first comparison result satisfying the abnormal condition corresponding to the first threshold and the second comparison result satisfying the abnormal condition corresponding to the second threshold, a preset device linkage priority rule is obtained, and the collaborative operation sequence of the first purification unit and the second purification unit is determined according to the device linkage priority rule, and a joint purification control instruction is generated based on the collaborative operation sequence.

[0085] Among them, the device linkage priority rules can be a strategy logic table or weight algorithm pre-stored in the server storage space, which is used to determine the intervention order or mutual exclusion relationship of different purification units in complex working conditions where multiple indicators are abnormal at the same time.

[0086] The collaborative runtime sequence can be a time axis scheduling scheme calculated based on linkage priority rules. It is used to plan the start time, duration and overlapping time window of each purification unit to ensure the orderliness and compatibility of physical equipment in operation.

[0087] The joint purification control command can be a composite control message generated by the server according to the timing scheme. It can coordinate multiple underlying hardware devices to act in an orderly manner according to the predetermined timing logic in order to achieve multi-target parallel purification operations.

[0088] For example, when the server detects through logical operations that both the first comparison result (e.g., excessive moisture) and the second comparison result (e.g., excessive particles) meet abnormal conditions within the same time judgment period, the server can trigger a multi-dimensional linkage control mode. Preset device linkage priority rules can be read by accessing the internal policy configuration database. These rules can be formulated based on the device's safety characteristics, energy consumption characteristics, or the chemical and physical characteristics of the purification process.

[0089] Subsequently, based on the read device linkage priority rules, the operation queues of the first and second purification units are arranged to determine whether they adopt a parallel, alternating, or delayed serial collaborative operation sequence. Based on the determined collaborative operation sequence, a joint purification control command containing multiple control code segments is generated and sent sequentially or in packages to the field controller, thereby driving the purification equipment to work collaboratively according to the planned rhythm. For example, considering that high moisture content may reduce the efficiency of electrostatic adsorption or even cause short circuit risks, the collaborative operation sequence can be planned to first start the first purification unit for dehydration, and then start the second purification unit for impurity removal after the moisture content has dropped to a safe level.

[0090] Optionally, the device linkage priority rule can also be constructed based on the mutual influence relationship between the first indicator data and the second indicator data. The server can have a pre-configured indicator correlation model, which characterizes the potential impact trend of changes in the first indicator (such as the content of a certain chemical component X) on the second indicator (such as the content of another component Y) (e.g., a 0.1% increase in the content of component X is expected to cause a corresponding increase in the value of component Y within a certain period). In this scenario, when the server detects that the first comparison result meets the abnormal condition (i.e., component X is abnormal), even if the second comparison result has not yet fully reached its independent alarm threshold or is only in a critical state, the server can still determine, based on the above correlation model, that the second indicator has a very high risk of deterioration or has already been substantially affected by the first indicator. Therefore, when generating control commands, the server will trigger the processing of another branch accordingly based on this correlation relationship. For example, while starting the first purification unit targeting the first indicator, it can preventively start the second purification unit, or dynamically increase the operating weight of the second purification unit in the collaborative runtime sequence, thereby achieving synchronous governance or preventative control of related indicators through the response to an abnormal indicator.

[0091] In this embodiment, by acquiring first and second indicator data representing different state dimensions in real time and comparing them with corresponding independent thresholds, accurate quantification and hierarchical identification of oil contamination types are achieved. Based on this, the system can selectively activate the corresponding purification unit when a single indicator is abnormal, avoiding equipment damage caused by blindly starting purification equipment, according to the judgment results of the abnormal mode. More importantly, for complex operating conditions with multiple indicators exhibiting concurrent abnormalities, by introducing equipment linkage priority rules and generating a collaborative runtime sequence, the problem of mutual interference caused by flow path conflicts resulting from the simultaneous operation of multiple devices is effectively solved. This ensures the safety of purification operations while improving the operational efficiency of the monitored target oil.

[0092] In one exemplary embodiment, after acquiring real-time monitoring data for the target oil, the method further includes:

[0093] The vibration data of the environment in which the target oil is located is acquired, and the current time point corresponding to the vibration data is recorded. If the vibration data is greater than the preset vibration interference threshold, the first index data and the second index data acquired at the current acquisition time point are discarded. If the vibration data is less than or equal to the preset vibration interference threshold, the first index data and the second index data are retained for comparison.

[0094] Vibration data can be a set of parameters that characterize the reciprocating motion state of the physical environment (such as oil pipes or unit casing) of the target oil in space, such as vibration amplitude, frequency or acceleration.

[0095] The vibration interference threshold can be a pre-set critical value used to define whether external mechanical vibration is sufficient to affect the signal-to-noise ratio of a precision oil sensor (such as an optical particle counter or a vibration-based viscometer).

[0096] Specifically, while acquiring the first and second indicator data through the monitoring terminal, the server can simultaneously acquire environmental vibration data within the specified time slice and assign a unified timestamp to these data to record the current acquisition time. The server then compares the acquired vibration amplitude with a pre-set vibration interference threshold in memory. If the server determines that the current vibration amplitude is greater than the threshold, it considers that the oil indicator data collected at the current moment may be superimposed with false signals caused by mechanical vibration (e.g., bubble oscillation misjudged as particles, or vibration causing viscosity probe reading drift). In this case, the server will mark and remove the first and second indicator data for that time point, not sending them into subsequent comparison logic. Conversely, if the vibration data is less than or equal to the threshold, the server determines that the current sampling environment is stable and the data is reliable, thus retaining this set of data for subsequent threshold comparison steps.

[0097] Alternatively, the server can also use a sliding window algorithm to interpolate and complete the data stream by using retained data from previous and subsequent time points after removing outliers, in order to maintain the continuity of the data stream.

[0098] In this embodiment, by introducing a verification mechanism for environmental vibration data, the validity of the source data is realized. This mechanism effectively solves the technical problem that high-precision oil sensors are easily affected by environmental noise interference and generate false alarms in high-vibration industrial sites such as water turbine units. It significantly improves the accuracy and robustness of subsequent purification control commands and avoids frequent false starts and stops of purification equipment due to sensor fluctuations caused by environmental interference.

[0099] In one exemplary embodiment, after generating the first purification control command, the method further includes:

[0100] An opening signal is sent to the first valve connected between the target oil circuit and the first purification unit, and a closing signal is sent to the second valve connected between the target oil circuit and the second purification unit, so as to guide the target oil to the first purification unit.

[0101] The first valve and the second valve can be fluid control actuators installed at the interface between the main oil circuit and each purification unit branch, such as electric ball valves, solenoid directional valves or pneumatic regulating valves, used to change the position of the internal valve core under the drive of an electrical signal to open or close the fluid passage.

[0102] Open and close signals can be used to drive the valves mentioned above to change their physical open or closed state.

[0103] Specifically, after the server generates the first purification control command, in order to ensure that the purification target corresponding to the command can be achieved, the server needs to construct a dedicated oil circuit to the first purification unit. The server can send a high-level opening signal to the first valve connected between the main oil circuit of the target oil and the oil inlet of the first purification unit, driving the valve to open; simultaneously or sequentially, the server sends a low-level closing signal to the second valve connected between the main oil circuit and the second purification unit (which does not need to operate at this time), driving the valve to close.

[0104] In complex pipeline networks with multiple valves linked together, the server can also send signals according to a preset timing sequence (e.g., opening first and then closing) to prevent instantaneous pressure buildup in the pipeline. Through the combined switching of the above valve states, the server physically cuts off the path of the oil to the second purification unit and forces the target oil to flow into the reaction chamber of the first purification unit.

[0105] In this embodiment, by precisely controlling the opening and closing states of valves connected to different branches, it is not only ensured that the oil to be treated can accurately enter the purification unit that matches its contamination type, but also that other purification units in standby state are effectively isolated, preventing unnecessary flushing of non-operating equipment by the oil in non-working units, thereby ensuring the operating order and efficiency of the entire hydraulic flow path.

[0106] In one exemplary embodiment, acquiring real-time monitoring data for the target oil includes:

[0107] The water content of the target oil is obtained by a moisture sensor as the first indicator data; the number of metal abrasive particles in the target oil is obtained by a particle counting sensor as the second indicator data.

[0108] Among them, water content can be a physical quantity that characterizes the water content in the oil, specifically expressed as relative saturation (water activity (aw)) or absolute content; the number of metal abrasive particles refers to the count value of metal particles with magnetic or electrical conductivity in a unit volume of oil, which is a key parameter reflecting the degree of mechanical wear.

[0109] Specifically, when performing the data acquisition step, the server can read the voltage or current signal transmitted by the moisture sensor through the analog input interface according to the pre-configured sensor mapping table, and convert it into a standardized moisture content value (e.g., 0-100% or 0-1000ppm (parts per million)), marking it as the first indicator data. Simultaneously, the server reads the message uploaded by the particle counting sensor through the digital communication interface, parses out the channel value representing the number of metal abrasive particles (e.g., the number of ferromagnetic particles >50μm), and marks it as the second indicator data.

[0110] Optionally, the server can also perform temperature compensation calculations on the acquired water content, converting the measured values ​​at different oil temperatures into values ​​at the standard temperature, in order to eliminate the impact of temperature fluctuations on the consistency of the indicators.

[0111] In this embodiment, by specifying the first indicator as water content and the second indicator as the number of metal abrasive particles, the core focus of the monitoring system is clearly defined. Water content is directly related to the oil's insulation and rust-preventing capabilities, while the number of metal abrasive particles is directly related to the wear state of mechanical components. Using these as input sources for linkage allows subsequent purification operations to precisely target the two most valuable maintenance objectives: dehydration and abrasion removal, thus improving the system's practicality and relevance.

[0112] In an exemplary embodiment, in response to an abnormal condition corresponding to a first threshold being met by a first comparison result, a first purification control instruction is generated, including:

[0113] In response to the abnormal condition corresponding to the first threshold met by the first comparison result, the current water content range to which the water content belongs is determined; based on the preset mapping relationship between the water content range and the oil inlet flow rate and the current water content range, a first purification control command characterizing the control of the oil inlet rate is determined to control the dehydration time of the target oil in the vacuum dehydration equipment.

[0114] The first purification unit includes a vacuum dehydration device.

[0115] The current moisture content range can be a number of discrete state ranges into which the continuous moisture content values ​​are divided by the server according to preset classification standards (such as low moisture content, medium moisture content, and high moisture content).

[0116] The mapping relationship between oil inlet flow rate and water content range can be a control strategy table or function curve pre-stored in the server, which represents the optimal fluid flux required to achieve the expected dehydration effect under different water loads.

[0117] The oil inlet rate refers to the volume of oil entering the vacuum dehydration equipment per unit time, which is usually achieved by adjusting the speed of the oil inlet pump or the opening of the flow regulating valve.

[0118] Specifically, when the server responds to the command to generate the first comparison result (abnormal moisture content), the server first determines which preset range the current real-time moisture content falls into (e.g., range C is 100-300 ppm, range D is 300-1000 ppm). If it is determined to fall into range D with higher moisture content, the server determines, based on the mapping relationship, that a slower oil inlet rate is needed to ensure the dehydration effect, and then generates a first purification control command containing the "low speed" parameter. This command is sent to the oil inlet pump of the vacuum dehydration equipment to control its speed to decrease. Conversely, if it falls into range C with lower moisture content, the server generates a command to increase the oil inlet rate. In this way, the server dynamically adjusts the flow rate of the oil in the vacuum tank, effectively controlling the residence time (dehydration) of the oil in the vacuum negative pressure environment: the higher the water content, the slower the flow rate, the longer the residence time, and the more thorough the separation.

[0119] In this embodiment, by establishing a dynamic mapping between water content range and oil inlet rate, this embodiment achieves refined adaptive control of the vacuum dehydration process, improving the energy efficiency ratio and operational targeting of the vacuum dehydration unit.

[0120] In an exemplary embodiment, in response to the second comparison result satisfying an abnormal condition corresponding to a second threshold, a second purification control instruction is generated, including:

[0121] In response to the abnormal condition corresponding to the second threshold, the current abrasive particle number range to which the number of metal abrasive particles belongs is determined; based on the preset mapping relationship between the abrasive particle number range and the electric field parameters and the current abrasive particle number range, a second purification control command characterizing the control discharge frequency or electric field strength is determined to control the degree of particle adsorption and agglomeration of the target oil in the electrostatic adsorption oil filtration equipment.

[0122] The second purification unit includes an electrostatic adsorption oil filtration device.

[0123] The current abrasive particle quantity range can be a data level range that the server classifies based on the severity of the metal abrasive particle quantity concentration (e.g., normal wear, early wear, severe wear stage).

[0124] The mapping relationship between the number range of abrasive particles and the electric field parameters can be the optimal combination of parameters set for different concentrations of metal particle loads in order to prevent breakdown between plates or improve the charging efficiency of particles of a specific size.

[0125] Specifically, when the server responds to the command to generate the second comparison result (the number of metal abrasive particles exceeds the limit), the server identifies the range of abrasive particle count to which the current number of metal abrasive particles belongs.

[0126] If the server determines that the number of abrasive particles is in an extremely high concentration range (which may cause a short circuit in the electric field under a fixed high voltage), the server generates a second purification control command based on the mapping relationship, which includes parameters that reduce the electric field strength but increase the discharge frequency, in order to maintain the adsorption force while avoiding breakdown.

[0127] If the server determines that the abrasive particle count is in the low to medium concentration range but mainly consists of tiny particles, it can generate commands with high electric field strength to enhance the capture of these tiny particles. The server sends these parameters to the high-voltage generator of the electrostatic purification unit, dynamically adjusting its output waveform to control the charging and agglomeration behavior of particles in the oil, thereby optimizing the adsorption effect.

[0128] In this embodiment, by dynamically adjusting the electric field parameters according to the range of metal abrasive particles, this embodiment overcomes the drawback of constant parameters in traditional electrostatic oil filters and achieves the optimal balance between safety and purification efficiency.

[0129] To enable those skilled in the art to better understand the above steps, the following example illustrates the embodiments of this application, but it should be understood that the embodiments of this application are not limited thereto.

[0130] In one exemplary embodiment, such as Figure 2 As shown, it specifically includes:

[0131] Step S100: Multidimensional data acquisition and anti-interference preprocessing.

[0132] For real-time monitoring data, which can be digital messages periodically read by the server from the front-end sensor array via an industrial bus, this data contains multi-dimensional information characterizing the current physicochemical properties of the target oil. Specifically, the server accesses a moisture sensor connected to the oil circuit to obtain the water content (e.g., water activity aw value or absolute water content ppm value), using this as the first indicator data. Simultaneously, the server accesses a particle counting sensor to obtain the number of metal abrasive particles (e.g., the count of ferromagnetic particles larger than 50 micrometers), using this as the second indicator data.

[0133] To ensure the accuracy of subsequent decisions, the server simultaneously acquires vibration data of the target oil's environment and records the current time point while reading the aforementioned indicators. Vibration data can be acceleration or amplitude signals characterizing the intensity of mechanical vibration near the monitoring point, used to assess whether the current moment is suitable for precise optical or electrical measurements. The server compares the acquired vibration data with a preset vibration interference threshold. If the vibration data exceeds this threshold (e.g., exceeding 0.5g), the server determines that the oil flow field is in a state of severe disturbance (such as bubble oscillation or fluid turbulence). In this case, the acquired first / second indicator data may have a large signal-to-noise ratio deviation, so the server performs a rejection operation, discarding the data at that time point to prevent misjudgment. Conversely, if the vibration data is less than or equal to the threshold, the server determines that the environment is stable, retains the indicator data at that time point, and sends it to the subsequent comparison logic.

[0134] Step S200: Threshold comparison and control logic splitting.

[0135] After acquiring valid indicator data, the server performs a comparison operation. The server retrieves a first threshold (e.g., a safe upper limit for moisture content) and a second threshold (e.g., a safe upper limit for particle count) preset in memory. It compares the first indicator data with the first threshold to obtain a first comparison result, and compares the second indicator data with the second threshold to obtain a second comparison result. Based on the states of these two comparison results, the server enters different control branches: if the first comparison result shows that the abnormal condition corresponding to the first threshold is met (e.g., excessive moisture content), and the second comparison result does not meet the abnormal condition, the server enters the first type of purification process; if the second comparison result shows that the abnormal condition corresponding to the second threshold is met (e.g., excessive particle count), and the first comparison result does not meet the abnormal condition, the server enters the second type of purification process; if both the first and second comparison results meet their respective abnormal conditions, the server enters a multi-dimensional linkage purification process.

[0136] Step S301: Vacuum dehydration control based on water content range. To achieve refined control, the server first determines the current water content range to which the current water content belongs. The server queries the preset mapping relationship between water content ranges and oil inlet flow rates to determine the target oil inlet rate corresponding to the current range. For example, if it is in a high water content range, the server determines that a lower oil inlet rate is needed to increase the residence time of the oil in the vacuum tank. Accordingly, the first purification control command generated by the server includes the frequency parameters for controlling the frequency converter of the oil inlet pump of the vacuum dehydration equipment (i.e., the first purification unit) to adjust the dehydration time.

[0137] After generating the instruction, the server performs an oil circuit switching operation. The server sends an open signal to the first valve connected between the target oil circuit and the first purification unit, and a close signal to the second valve connected between the target oil circuit and the second purification unit. This action physically guides the oil to the vacuum dehydration equipment while isolating the electrostatic adsorption equipment, achieving targeted dehydration treatment.

[0138] Step S302: Electrostatic adsorption control based on the range of metal abrasive particle counts. The server first parses the second indicator data to determine the current range of abrasive particle counts. Based on a preset mapping relationship between the abrasive particle count range and electric field parameters, the server determines the appropriate discharge frequency or electric field strength. For example, when the number of metal abrasive particles is extremely high, to prevent electrode breakdown, the mapping relationship may point to a higher pulse discharge frequency and a appropriately reduced voltage amplitude. The server then generates a second purification control command and sends it to the high-voltage generator of the electrostatic adsorption oil filtration equipment (i.e., the second purification unit), thereby controlling the degree of particle adsorption and agglomeration within the equipment and maximizing adsorption efficiency while ensuring safety.

[0139] Similarly, if this process needs to be run independently, the server will send a signal to open the second valve and close the first valve (or keep it closed), guiding the oil flow through the electrostatic adsorption unit.

[0140] Step S303: Multi-dimensional linkage purification treatment and coordinated operation sequence control. The server obtains preset device linkage priority rules. These rules can be based on device protection principles (e.g., prohibiting electrostatic adsorption under high moisture conditions to prevent short circuits). According to these rules, the server determines the coordinated operation sequence of the first purification unit and the second purification unit.

[0141] For example, the defined timing sequence might be: first, the first purification unit operates at full power for dehydration; then, after the monitored moisture content drops to a safe threshold, the second purification unit is activated for particle adsorption. Based on this coordinated operating sequence, the server generates a joint purification control command. This command is a control sequence containing timeline information, instructing the underlying controller to first open the first valve and initiate vacuum dehydration, run for a specific time or meet specific conditions, then open the second valve (if it's a series oil circuit) or switch the valve state, and initiate electrostatic adsorption with specific electric field parameters. This coordinated control avoids conflicts between devices, ensuring purification safety and efficiency under complex operating conditions.

[0142] In this embodiment, the accuracy of control input is ensured by acquiring real-time moisture content and the number of metal abrasive particles and combining this with environmental vibration data for cleaning. By comparing the index data with thresholds and directly mapping them to specific control branches, rapid response to single faults and intelligent linkage for compound faults are achieved. In particular, in handling single faults, fine-grained control is achieved by mapping moisture content / abrasive particle number to oil inlet rate / electric field parameters. In handling compound faults, the coordinated operation sequence determined by priority rules effectively solves the conflict between high moisture content and electrostatic adsorption, realizing fully automatic and highly efficient closed-loop management of the oil state of the water pump turbine unit while ensuring equipment safety.
