[0002] In the field of underwater operations, various equipment are being used more and more widely. Among them, due to the particularity of the use environment of many underwater equipment, the electrical devices must be installed in watertight compartments to ensure the normal operation and safety of the equipment. However, for some devices that need to be used continuously and will continue to generate heat during operation, this brings severe challenges. When the thermal conductivity of the watertight compartment is poor, the heat generated by the operation of the equipment is difficult to be transferred to the water outside through the watertight bulkhead in time. As the equipment continues to operate, the heat continues to accumulate, and the temperature in the sealed compartment is bound to continue to rise, which will not only affect the performance and stability of the equipment, but may also cause the equipment to be unable to be used normally for a long time, and may even cause equipment failure, which will have a serious impact on the smooth progress of underwater operations. Summary of the invention

The heat-generating device is tightly wrapped by the heat-conducting coating box, and a circulation loop is formed with the cabin coolant tank through the coolant outlet pipe and the coolant return pipe. The circulating liquid pump drives the coolant to circulate continuously, which can quickly absorb the heat generated by the equipment during operation, and ensure that the heat is continuously transferred from the heat-generating device to the coolant; and the heat-conducting component is arranged in the first inner cavity. The heat of the heat-generating device is concentrated at one end of the cabin coolant tank through the heat-conducting component. This design effectively follows the principle of taking the heat away from the heat-generating device as quickly as possible and concentrating the heat in a local area away from the device area. On the one hand, the heat is concentrated to increase the temperature difference between the inside and outside of the cabin. On the other hand, the speed of heat transfer to the outside of the cabin is greatly accelerated, thereby efficiently cooling the heat-generating device.

By adopting the annular coolant channel, the problem of low heat dissipation efficiency caused by the mixing of coolant before and after heat absorption is effectively solved, which has significant technical advantages in improving the heat dissipation performance and reliability of the equipment.

[0006] Furthermore, the liquid outlet is provided with a first temperature sensor, and the first temperature sensor is used to detect the coolant temperature at the liquid outlet. By providing the first temperature sensor at the liquid outlet, real-time monitoring of the coolant temperature can be achieved, ensuring that the cooling system can be adjusted according to the actual temperature conditions, and avoiding performance degradation or failure of the equipment due to overheating.

[0007] Furthermore, the liquid return end is provided with a second temperature sensor, and the second temperature sensor is used to detect the temperature of the coolant at the liquid return end.

[0010] Furthermore, the heat conduction assembly further includes a plurality of heat conduction teeth distributed on the wall surface of the first inner cavity. By distributing a plurality of heat conduction teeth on the wall surface of the first inner cavity, the contact area between the coolant and the heat conduction teeth is significantly increased, thereby improving the heat exchange efficiency of the cabin coolant tank.

[0011] Furthermore, a first connecting port is provided on the thermal conductive coating box, and the thermal conductive coating box is connected to the coolant outlet pipe through the first connecting port, and a water inlet flow meter is provided at the connecting end of the coolant outlet pipe close to the thermal conductive coating box.

[0012] Furthermore, a second communication port is provided on the thermal conductive coating box, and the thermal conductive coating box is connected to the coolant return pipe through the second communication port, and a water outlet flow meter is provided at the connecting end of the coolant return pipe close to the thermal conductive coating box. This design can effectively solve the problem of flow monitoring of the coolant when the coolant outlet pipe is connected to the thermal conductive coating box, thereby ensuring the stable operation of the cooling system.

[0013] Furthermore, the thermally conductive coating box includes a flow partition, and the flow partition is arranged between the first connecting port and the second connecting port. First, the flow partition is located between the first connecting port and the second connecting port, and can play a certain role in guiding and separating the flow of the coolant. It can optimize the flow path of the coolant in the thermally conductive coating box, so that the coolant flows through the external heating device more evenly, and improves the efficiency of heat absorption. At the same time, the flow partition can reduce the turbulence phenomenon that may occur in the coolant in the thermally conductive coating box, reduce the flow resistance, and thus reduce the energy consumption of the circulating liquid pump. In addition, the flow partition can also enhance the structural strength of the thermally conductive coating box to a certain extent, and improve the stability and reliability of the entire heat dissipation device. In short, the setting of the flow partition provides a more effective guarantee for the heat dissipation of the closed cabin heating device.

It is suitable for a variety of scenarios with strict heat dissipation requirements, and improves the performance and stability of the overall system.

[0015] Furthermore, the method of obtaining the temperature index according to the liquid outlet temperature, the liquid return temperature and the preset first fuzzy set includes: performing data standardization on the liquid outlet temperature, the liquid return temperature and the coating box temperature, and converting them to the processing range of the first fuzzy set; defining a membership function for each fuzzy subset according to the first fuzzy set to obtain a first membership function of each fuzzy subset; calculating the membership of the liquid outlet temperature, the liquid return temperature and the coating box temperature to each fuzzy subset according to the first membership function to obtain a first membership set; and obtaining the temperature index by using a fuzzy reasoning method and the first membership set. First, the data of the outlet temperature and the return temperature are standardized to ensure that data in different temperature ranges can be processed under a unified framework to avoid inaccurate evaluation due to large differences, laying the foundation for subsequent analysis; then, the membership function is defined based on the first fuzzy set, and the division boundary of the temperature state is clarified, so that different temperature conditions have more specific attribution; the first membership set is obtained by calculating the membership, and the degree of temperature in different fuzzy subsets is quantified, providing data support for a comprehensive understanding of the temperature state; finally, the fuzzy reasoning method is combined with the first membership set to calculate the temperature index, realizing intelligent evaluation, which can adapt to complex temperature changes.

The normalization process ensures that the first flow value and the second flow value are comparable and eliminates the dimensional difference. By defining a membership function for each fuzzy subset of the second fuzzy set, the fuzzy attributes of the flow value are quantified, providing a basis for fuzzy logic reasoning. The calculated second membership set reflects in detail the degree of membership of the flow value in each fuzzy subset, enhancing the description ability of the fuzzy set. Finally, the weighted average method is used in combination with the second membership set to calculate the flow index, so that the obtained index is more objective and comprehensive, and the accuracy of decision-making and the responsiveness of the system are improved.

The external heating device can also be a car engine, a ship engine, an aircraft engine, etc.; the circulating liquid pump 5 adopts a low-power internal circulation pump. There are two circulating liquid pumps 5, namely a main water pump and an auxiliary water pump. The main water pump is in use and the auxiliary water pump serves as a backup pump. When the main water pump fails, the main water pump reports the fault information to the control device, realizing the redundant design of the switching mode of the two sets of circulating liquid pumps, thereby increasing the reliability of the heat dissipation device.

[0022] The heat-generating device is tightly wrapped by the heat-conducting coating box 1, and a circulation loop is formed with the cabin coolant tank 2 through the coolant outlet pipe 3 and the coolant return pipe 4. The circulating liquid pump 5 drives the coolant to circulate continuously, which can quickly absorb the heat generated by the equipment during operation, and ensure that the heat is continuously transferred from the heat-generating device to the coolant; and the heat-conducting component 6 is arranged in the first inner cavity 26. The heat of the heat-generating device is concentrated at one end of the cabin coolant tank 2 through the heat-conducting component 6. This design effectively follows the principle of taking the heat away from the heat-generating device as quickly as possible and concentrating the heat in a local area away from the device area. On the one hand, the heat is concentrated to increase the temperature difference between the inside and outside of the cabin, and on the other hand, the speed of heat transfer to the outside of the cabin is greatly accelerated, thereby efficiently cooling the heat-generating device.

[0023] The first inner cavity 26 is provided with a liquid level sensor 23, and the liquid level sensor 23 measures the liquid level of the coolant in the cabin coolant tank 2, thereby effectively solving the problem of coolant level measurement and ensuring the normal operation and safety of the equipment.

[0024] In this embodiment, the number of the liquid level sensors 23 is two, and the liquid level sensors 23 can be of various types, such as float type liquid level sensors, capacitive liquid level sensors, ultrasonic liquid level sensors, etc.; the float type liquid level sensor measures the liquid level height by the up and down movement of the float, the capacitive liquid level sensor detects the liquid level by the change of capacitance, and the ultrasonic liquid level sensor determines the liquid level position by transmitting and receiving ultrasonic signals; as a preferred embodiment, the liquid level sensor can be installed on the upper side wall of the cabin coolant tank 2 to accurately detect the change of the coolant level; in addition, the liquid level sensor can also be connected to the control device, and when the abnormal liquid level is detected, corresponding measures can be taken in time to further improve the safety and reliability of the system.

[0025] An annular coolant channel 24 is provided in the first inner cavity 26, one end of the annular coolant channel 24 is connected to the liquid outlet 21, and the other end of the annular coolant channel 24 is connected to the liquid return end 22, thereby realizing effective separation and circulation of the coolant. The annular coolant channel 24 is used to isolate the coolant before heat absorption and the coolant after heat absorption, thereby avoiding mixing of the coolant before and after heat absorption, thereby improving the heat dissipation efficiency.

[0026] In this embodiment, the annular coolant channel 24 can be directly processed from the main body of the cabin coolant tank 2. The annular coolant channel 24 can also be implemented in a variety of ways. For example, it can be implemented by setting an independent annular pipe in the cabin coolant tank 2. The material of the annular channel can be selected from metal materials with good thermal conductivity to further improve the heat dissipation effect. In addition, the cross-sectional shape and size of the annular channel can be optimized according to actual needs to ensure smooth flow of the coolant and optimal heat dissipation effect.

[0027] By adopting the annular coolant channel 24, the problem of low heat dissipation efficiency caused by mixing of coolant before and after heat absorption is effectively solved, which has significant technical advantages in improving the heat dissipation performance and reliability of the equipment.

[0028] The liquid outlet 21 is provided with a first temperature sensor 211, which is used to detect the temperature of the coolant at the liquid outlet 21. By providing the first temperature sensor 211 at the liquid outlet, the temperature of the coolant at the liquid outlet can be monitored in real time, thereby effectively grasping the temperature change of the coolant.

[0029] The first temperature sensor 211 can be in various forms, such as a thermocouple, a thermistor, or an integrated temperature sensor chip. Thermocouples have the characteristics of fast response speed and wide measurement range, and are suitable for environments that are sensitive to temperature changes. Thermistors have high sensitivity and good linearity, and are suitable for accurately measuring temperature changes within a specific temperature range. Integrated temperature sensor chips have the advantages of small size and high integration, and are suitable for application environments with limited space; By arranging the first temperature sensor 211 at the liquid outlet, real-time monitoring of the coolant temperature can be achieved, ensuring that the cooling system can be adjusted according to the actual temperature conditions, thereby avoiding performance degradation or failure of the equipment due to overheating.

[0034] A watertight bulkhead 25 is arranged outside the first inner cavity 26 , and the watertight bulkhead 25 is a hemispherical surface. The heat-conducting component 6 includes a hemispherical heat-conducting wall 61 , which is adapted to the watertight bulkhead 25 and is arranged on the inner wall surface of the watertight bulkhead 25 .

[0035] The watertight bulkhead 25 is a hemispherical surface, and the design function of the hemispherical heat-conducting wall 61 that is adapted to the watertight bulkhead 25 is to increase the heat exchange surface area of ​​the cabin coolant tank 2, thereby improving the heat exchange efficiency and ensuring that the heat can be effectively transferred from the coolant to the hemispherical heat-conducting wall 61. Through this design, the problem of poor heat dissipation of the heating equipment in the cabin can be effectively solved, ensuring the stable operation and safety of the equipment. The design of the hemispherical heat-conducting wall 61 can adopt a variety of materials, such as copper, aluminum and other metal materials with high thermal conductivity, to further enhance the thermal conductivity effect.

[0036] By adopting the design of the hemispherical heat-conducting wall 61, the heat exchange surface area is effectively increased, which can significantly improve the heat exchange efficiency of the cabin coolant tank 2, ensuring that heat can be quickly transferred to the hemispherical heat-conducting wall 61, thereby ensuring the stable operation and safety of the equipment.

[0037] The heat-conducting component 6 also includes a plurality of heat-conducting teeth 62 distributed on the wall surface of the first inner cavity 26. By adding a plurality of the heat-conducting teeth 62 on the wall surface of the first inner cavity 26, the contact area between the coolant and the heat-conducting teeth 62 is increased, so that the heat-conducting teeth 62 can quickly take away the heat of the coolant, thereby improving the heat exchange efficiency; the design of the heat-conducting teeth 62 can be in various forms, for example, the heat-conducting teeth 62 can be made of metal materials with high thermal conductivity, such as copper or aluminum; in order to enhance the heat conduction effect, a plurality of the heat-conducting teeth 62 can be distributed on the surface of the hemispherical heat-conducting wall 61 to increase its surface area; the heat-conducting teeth 62 are arranged on the surface of the annular coolant channel 24 to increase its surface area, thereby further improving the heat exchange efficiency; the number and distribution of the heat-conducting teeth 62 can be adjusted according to specific heat conduction requirements to achieve the best heat conduction effect.

[0038] By distributing a plurality of heat-conducting teeth 62 on the wall surface of the first inner cavity 26 , the contact area between the coolant and the heat-conducting teeth 62 is significantly increased, thereby improving the heat exchange efficiency of the cabin coolant tank 2 .

[0039] The thermally conductive coating box 1 is provided with a first connecting port 11, and the thermally conductive coating box 1 is connected with the coolant outlet pipe 3 through the first connecting port 11. The setting of the first connecting port 11 enables the coolant outlet pipe 3 to be smoothly connected to the thermally conductive coating box 1. The coolant outlet pipe 3 is provided with an inlet flow meter 31 at the connecting end close to the thermally conductive coating box 1. The setting of the inlet flow meter 31 ensures that the flow of the coolant in the coolant outlet pipe 3 is monitored.

[0040] The coolant outlet pipe 3 is made of a material with poor heat conductivity, for example, a plastic material such as polypropylene, polyethylene, etc. These plastic materials have good insulation properties and can effectively reduce the heat transferred to the surrounding environment through the coolant outlet pipe 3; This design can effectively solve the problem of flow monitoring of the coolant when the coolant outlet pipe 3 is connected to the thermal conductive coating box 1, thereby ensuring the stable operation of the cooling system.

[0041] A second connecting port 12 is provided on the thermally conductive coating box 1, and the thermally conductive coating box 1 is connected to the coolant return pipe 4 through the second connecting port 12. The setting of the second connecting port 12 enables the coolant return pipe 4 to be smoothly connected to the thermally conductive coating box 1. The coolant return pipe 4 is provided with an outlet flow meter 41 at the connecting end close to the thermally conductive coating box 1. The setting of the outlet flow meter 41 ensures that the flow of the coolant in the return pipe is monitored.

[0042] This design can effectively solve the problem of flow monitoring of the coolant when the coolant outlet pipe 3 is connected to the thermal conductive coating box 1, thereby ensuring the stable operation of the cooling system.

[0043] The thermally conductive coating box 1 includes a flow partition 13, which is arranged between the first connecting port 11 and the second connecting port 12. By arranging the flow partition 13 between the first connecting port 11 and the second connecting port 12, the flow path of the coolant in the thermally conductive coating box 1 is optimized.

[0044] First, the flow partition 13 is located between the first connecting port 11 and the second connecting port 11, and can guide and separate the flow of the coolant to a certain extent. It can optimize the flow path of the coolant in the thermally conductive coating box 1, so that the coolant flows through the external heating device more evenly, and improves the efficiency of heat absorption. At the same time, the flow partition 13 can reduce the turbulence phenomenon that may occur in the coolant in the thermally conductive coating box 1, reduce the flow resistance, and thus reduce the energy consumption of the circulating liquid pump 5. In addition, the flow partition 13 can also enhance the structural strength of the thermally conductive coating box 1 to a certain extent, and improve the stability and reliability of the entire heat dissipation device. In short, the setting of the flow partition 13 provides a more effective guarantee for the heat dissipation of the closed cabin heating device.

[0045] In the field of heat dissipation of closed cabin heating equipment, the existing technology usually adopts a relatively simple heat dissipation method, generally only monitoring the temperature of the heating equipment through a single temperature sensor, and cannot fully and accurately grasp the operating status of the heat dissipation system. Moreover, there is a lack of effective monitoring means for the circulation of the coolant, and it is difficult to ensure that the coolant is always circulated at an appropriate flow rate, which may lead to unstable heat dissipation efficiency; at the same time, the existing technology is also relatively weak in monitoring the amount of coolant, and cannot promptly detect insufficient or excessive coolant, which is easy to affect the heat dissipation effect and even cause safety hazards; in addition, the existing technology lacks an intelligent early warning mechanism, and cannot provide early warning and accurate response to possible problems in the heat dissipation system, which makes the closed cabin heating equipment face a high risk of failure during operation, seriously affecting the reliability and safety of the equipment and shortening the service life of the equipment.

[0046] An intelligent control safety warning method is used to control the heat dissipation device of a closed cabin heating device as described above. 101: Obtaining data from the water inlet flow meter 31 and the water outlet flow meter 41 to obtain a first flow value and a second flow value; by accurately grasping the flow conditions of the coolant at different positions of the heat dissipation system, it is convenient to timely find out whether the coolant circulation is normal; In order to provide data support for optimizing the operation of the heat dissipation system, the working state of the circulating liquid pump 5 can be adjusted according to the flow value to achieve more efficient heat dissipation.

[0047] 102: Obtain data from the first temperature sensor 211, the second temperature sensor 221 and the third temperature sensor 271 to obtain the liquid outlet temperature, the liquid return temperature and the coating box temperature, and monitor the temperature changes of the coolant at different stages in real time, which can intuitively reflect the heat dissipation effect of the heat-generating equipment.

[0048] 103: Obtaining data from the liquid level sensor 23 to obtain liquid level height data to ensure that the amount of coolant in the coolant tank is at an appropriate level. 104: A temperature index is obtained according to the liquid outlet temperature, the liquid return temperature, the coating box temperature and the preset first fuzzy set. The temperature data is processed by the first fuzzy set to more accurately evaluate the temperature state of the heating device. Different temperature ranges correspond to different temperature indexes, which provides a more scientific basis for the subsequent determination of the warning level. 105: Obtaining a flow index according to the first flow value, the second flow value and a preset second fuzzy set, and analyzing the flow data using the second fuzzy set, so as to comprehensively consider the flow change of the coolant at different positions, and more comprehensively reflect the operation status of the cooling system. Different flow combinations correspond to different flow indexes, and provide a more accurate reference for judging the cooling effect and potential problems; 106: obtaining a liquid level index according to the liquid level height data and the preset third fuzzy set, and processing the liquid level data by the third fuzzy set to more accurately determine the liquid level state in the cabin coolant tank 2, providing an important basis for comprehensively evaluating the safety and reliability of the cooling system; 107: According to the temperature index, flow index, liquid level index and the preset fuzzy rules, the warning level fuzzy set is obtained. Taking the three key factors of temperature, flow and liquid level into consideration, the warning level fuzzy set is obtained through the preset fuzzy rules, which can more comprehensively and accurately evaluate the risk level of the cooling system. Different combinations of indicators correspond to different warning levels, providing a scientific basis for taking corresponding warning and treatment measures in a timely manner; 108: Generate warning instructions based on the warning level fuzzy set and the preset risk response library. Combined with the warning level fuzzy set and the preset risk response library, it is possible to quickly and accurately generate corresponding warning instructions to ensure that the most appropriate response measures are taken in different risk situations.

[0049] The present embodiment provides a comprehensive and intelligent solution for the heat dissipation device of the closed cabin heating equipment. The types of early warning instructions include instructions for accelerating the speed of the circulating liquid pump, instructions for starting the auxiliary liquid pump, instructions for repairing the leakage point, instructions for automatically replenishing the coolant and instructions for stopping the replenishment operation, etc.; the flow value is obtained by the water inlet flowmeter 31 and the water outlet flowmeter 41, and the circulation of the coolant can be accurately monitored; the temperature of the liquid outlet end, the return liquid end and the coating box is obtained by the temperature sensor, and the temperature index is obtained by combining the fuzzy set, so that the temperature change of the heating equipment can be detected in time; the coolant volume is monitored by the liquid level sensor 23, and the early warning level fuzzy set is obtained by using multiple indicators and fuzzy rules, and then the early warning instruction is generated according to the risk response library, so as to realize early warning and accurate response to the cooling system; this scheme improves the reliability and safety of the heat dissipation device, extends the life of the closed cabin heating equipment, and provides a strong guarantee for the stable operation of the closed cabin heating equipment. It is suitable for a variety of scenarios with strict heat dissipation requirements, and improves the performance and stability of the overall system.

[0050] The temperature index is obtained according to the liquid outlet temperature, the liquid return temperature and a preset first fuzzy set, including: 201: Standardize the data of the liquid outlet temperature, liquid return end temperature and coating box temperature, and convert them to the processing range of the first fuzzy set to ensure that data in different temperature ranges can be processed under a unified standard to avoid inaccurate subsequent processing due to huge differences in temperature values; 202: defining a membership function for each fuzzy subset according to the first fuzzy set to obtain a first membership function of each fuzzy subset; 203: Calculate the membership of the liquid end temperature, the liquid return end temperature and the coating box temperature to each fuzzy subset according to the first membership function to obtain the first membership set, which divides clear boundaries for different temperature states. The first membership function can be used to determine the degree of belonging of temperature data in different fuzzy subsets; 204: The temperature index is calculated by using the fuzzy reasoning method and the first membership set, which provides an intelligent means for temperature evaluation. By performing fuzzy reasoning on the first membership set, it can automatically adapt to different temperature changes, thereby improving the accuracy and reliability of the temperature index.

[0051] First, the data of the outlet temperature and the return temperature are standardized to ensure that data in different temperature ranges can be processed under a unified framework to avoid inaccurate evaluation due to large differences, laying the foundation for subsequent analysis; then, the membership function is defined based on the first fuzzy set, and the division boundary of the temperature state is clarified, so that different temperature conditions have more specific attribution; the first membership set is obtained by calculating the membership, and the degree of temperature in different fuzzy subsets is quantified, providing data support for a comprehensive understanding of the temperature state; finally, the fuzzy reasoning method is combined with the first membership set to calculate the temperature index, realizing intelligent evaluation, which can adapt to complex temperature changes. This scheme improves the accuracy and reliability of temperature evaluation, provides a scientific basis for the early warning and control of the cooling system, ensures the stable operation of the equipment, and extends the life of the equipment.

By defining a membership function for each fuzzy subset, the degree to which each flow value belongs to each fuzzy subset, ie, their membership degree, can be quantified.

[0053] 303: Calculate the membership of the first flow value and the second flow value to each fuzzy subset according to the second membership function to obtain a second membership set, quantify the degree of belonging of the first flow value and the second flow value in different fuzzy subsets, and by calculating the membership, it can be clear which fuzzy subset the flow is more inclined to, providing specific data support for further analysis and decision-making; 304: The flow index is obtained by using the weighted average method and the second membership set. The weighted average method is a commonly used comprehensive evaluation method. It can calculate the final flow index according to the membership of each fuzzy subset and the corresponding weight. This method takes into account the importance of different fuzzy subsets, making the flow index more objective and comprehensive. The flow index obtained in this way can more accurately reflect the actual flow conditions and provide a reliable basis for further analysis and decision-making.

[0054] This embodiment ensures the comparability of the first flow value and the second flow value through normalization processing, eliminates dimensional differences, and quantifies the fuzzy attributes of the flow value by defining a membership function for each fuzzy subset of the second fuzzy set, thereby providing a basis for fuzzy logic reasoning; the calculated second membership set reflects in detail the membership degree of the flow value in each fuzzy subset, thereby enhancing the descriptive ability of the fuzzy set; finally, the weighted average method is used in combination with the second membership set to calculate the flow index, so that the obtained index is more objective and comprehensive, thereby improving the accuracy of decision-making and the responsiveness of the system.

[0055] The step of obtaining the liquid level index according to the liquid level height data and a preset third fuzzy set includes: 401: Use statistical methods to normalize the liquid level height data. By using statistical methods to normalize the liquid level height data, the liquid level height data can be converted to a unified scale, eliminating the influence of different dimensions and magnitudes, which is convenient for subsequent comparison and analysis; 402: defining a membership function for each fuzzy subset according to the third fuzzy set to obtain a third membership function of each fuzzy subset. By defining the membership function, the fuzzy attribute of the liquid level height data is quantified, thereby enhancing the descriptive ability and accuracy of the model. 403: Calculating the membership of the liquid level height data to each fuzzy subset according to the third membership function to obtain a third membership set. The calculated membership can accurately reflect the membership of the liquid level height data in each fuzzy subset, and provide detailed data support for further processing and decision-making of the fuzzy set. 404: The weighted average method and the third membership set are used to obtain the liquid level index. The weighted average method combined with the third membership set is used to calculate the liquid level index, which can comprehensively consider the importance of different fuzzy subsets and obtain a more comprehensive and objective liquid level index, thereby improving the accuracy of decision-making.

[0056] This embodiment uses statistical methods to normalize the liquid level height data and flow value to ensure that the data are on the same scale for easy comparison and analysis; by defining a membership function for each fuzzy subset of the third fuzzy set, the fuzzy attributes of the liquid level and flow are quantified; the calculated membership set reflects in detail the membership degree of the liquid level and flow value in each fuzzy subset, thereby enhancing the descriptive ability of the fuzzy set; the weighted average method is combined with the membership set to calculate the liquid level and flow indexes, comprehensively considering the importance of different fuzzy subsets, obtaining more comprehensive and objective indicators, and improving the accuracy of decision-making and the responsiveness of the system; this method not only improves the flexibility and adaptability of data processing, but also enhances the ability to evaluate and predict the state of complex systems.
