Description

Technical Field

[0001] This invention relates to the field of temperature control, specifically to a high-efficiency circulating cooling system and control method for vacuum isothermal forging, and a storage medium. Background Technology

[0002] Vacuum isothermal forging is a precision forging technique that requires maintaining a constant temperature throughout the forging process to ensure the uniformity of the material's internal structure and properties. Closed-loop cooling water provides stable and controllable cooling capacity, meeting the temperature requirements of isothermal forging.

[0003] The prior art, such as the invention patent with announcement number CN102402233B, is an automatic control device for a transformer cooling system, including an air switch ZK, a relay BC1 contact BC1-1, a submersible oil pump thermal protection relay BRJ, and a cooler fan thermal protection relay FRJ. The feature is that a relay contact BC2-1 for controlling the operation of the cooler fan is connected between the cooler fan thermal protection relay FRJ and the relay contact BC1-1, and the relay BC2 is connected to the relay BC2 power control circuit composed of a temperature control switch.

[0004] Existing technology, such as the invention patent with publication number CN118732728B, is a method, device, equipment, and storage medium for monitoring the temperature of a radiator. The method includes: acquiring environmental parameter ranges and fan operation information corresponding to various working environments of the current device; determining a fan speed adjustment strategy based on the fan operation information; adjusting the speed of each fan in the current device according to the fan speed adjustment strategy under each set of environmental parameters corresponding to each working environment, and acquiring the temperature of each radiator to obtain the radiator temperature under each set of environmental parameters corresponding to each working environment; constructing a target temperature protection curve for each radiator based on the radiator temperature under each set of environmental parameters corresponding to each working environment; and monitoring the temperature of each radiator based on the target temperature protection curve, the real-time temperature of each radiator, and the current environmental parameters of the device.

[0005] As can be seen from the above solutions, existing technologies in the field of automatic temperature control often rely on fixed-configuration thermal protection relays, which may not be able to adapt to different cooling demand changes. In practical applications, cooling demand may gradually change as cooling progresses. Due to the combined influence of multiple factors, temperature changes are often complex and difficult to predict. When performing temperature control, simply configuring fixed hardware parameters may cause deviations in temperature control results, leading to unsatisfactory temperature control effects. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a high-efficiency circulating cooling system and control method for vacuum isothermal forging, as well as a storage medium. To achieve the above objectives, this invention utilizes the following technical solution: a high-efficiency circulating cooling system and control method for vacuum isothermal forging, and a storage medium, comprising:

[0007] The initial self-test module is used to check the patency of the cooling water pipeline at the initial moment of starting vacuum isothermal forging and obtain the patency test result. If the patency test result is unqualified, an early warning is sent to the management terminal. If the patency test result is qualified, an automatic forging start signal is generated and sent to the switch controller to control the start of vacuum isothermal forging.

[0008] The sensing and monitoring module is used to acquire the real-time temperature of the forging chamber and send it to the data processing module, and at the same time monitor the real-time water flow parameters in the cooling water pipes and send them to the data processing module.

[0009] The external environment monitoring module is used to acquire external environmental parameters of the cooling water pipeline, comprehensively analyze and process them to obtain the external environmental impact correction factor, and send it to the data processing module.

[0010] The data processing module is used to obtain the required cooling water flow rate of the forging chamber based on the real-time temperature analysis of the forging chamber, and to obtain the transmission loss influence factor of the cooling water pipeline based on the real-time water flow parameters of the cooling water pipeline and the external environmental influence correction factor. The total required cooling water flow rate of the forging chamber is obtained by comprehensively analyzing the required cooling water flow rate of the forging chamber and the transmission loss influence factor of the cooling water pipeline.

[0011] The feedback processing module is used to match and obtain the dynamic adjustment value of the rotational speed of the closed-loop pumping unit based on the total flow rate of cooling water required in the forging chamber, and to dynamically adjust the rotational speed of the closed-loop pumping unit.

[0012] As a preferred technical solution, the specific process of performing a flow test on the cooling water pipeline is as follows:

[0013] A sound wave transmitter installed at the inlet of the cooling water pipe sends a pure tone sinusoidal sound wave signal with a preset frequency and amplitude to the cooling water pipe. After receiving the pure tone sinusoidal sound wave signal, a sound wave receiver installed at the outlet of the cooling water pipe obtains the transmission signal parameters of the pure tone sinusoidal sound wave, including the velocity, frequency, maximum amplitude, and waveform function of the pure tone sinusoidal sound wave signal. Based on the transmission signal parameters of the pure tone sinusoidal sound wave, the unobstructedness assessment value of the cooling water pipe is obtained through analysis and processing. The unobstructedness assessment value of the cooling water pipe is used to assess whether there is a blockage in the cooling water pipe.

[0014] As a preferred technical solution, obtaining the cooling water pipeline unobstructedness test result specifically includes:

[0015] If the unobstructedness assessment value of the cooling water pipeline is less than or equal to the unobstructedness assessment threshold, the unobstructedness test result of the cooling water pipeline is determined to be unqualified, and an early warning is sent to the management terminal.

[0016] If the unobstructedness assessment value of the cooling water pipeline is greater than the unobstructedness assessment threshold, the unobstructedness test result of the cooling water pipeline is deemed qualified, and an automatic forging start signal is generated to the switch controller to control the start of vacuum isothermal forging.

[0017] As a preferred technical solution, the acquisition of external environmental parameters of the cooling water pipeline and the comprehensive analysis and processing to obtain an external environmental impact correction factor specifically include:

[0018] The external environmental parameters of the cooling water pipeline include the real-time external temperature, real-time external humidity, and real-time external air pressure at each screening point.

[0019] External temperature, external humidity, and external air pressure verification values ​​are extracted from the database and analyzed with external environmental parameters to obtain the external environmental impact correction factor.

[0020] As a preferred technical solution, the step of obtaining the required cooling water flow rate for the forging chamber based on real-time temperature analysis and processing specifically includes:

[0021] Based on the real-time temperature of the forging chamber, a comparison is made with the set cooling temperature. If the real-time temperature of the forging chamber is less than or equal to the set cooling temperature, a minimum speed signal is sent to the closed-loop pumping unit, causing the closed-loop pumping unit to operate at the minimum speed to reduce the cooling water flow. The difference between the real-time temperature of the forging chamber and the set cooling temperature is calculated to obtain the required heating temperature difference. Based on the required heating temperature difference, a mapping and matching is performed with the heater power adjustment values ​​corresponding to each required heating temperature difference range pre-stored in the database to obtain the power adjustment value of the heater in the forging chamber, and control is executed.

[0022] If the real-time temperature of the forging chamber is greater than the set cooling temperature, the difference is calculated to obtain the cooling temperature difference. The cooling temperature difference is then mapped and matched with the cooling water flow rate corresponding to each cooling temperature difference range stored in the database to obtain the required cooling water flow rate for the forging chamber.

[0023] As a preferred technical solution, the transmission loss influence factor of the cooling water pipeline is obtained by processing the real-time water flow parameters and external environmental influence correction factors of the cooling water pipeline, specifically including:

[0024] The real-time water flow parameters of the cooling water pipeline are processed to obtain the real-time water flow characteristic value of the cooling water pipeline. Combined with the smoothness assessment value of the cooling water pipeline and the external environmental influence correction factor, the transmission influence characteristic value of the cooling water pipeline is obtained. The transmission influence characteristic value of the cooling water pipeline is mapped and matched with the transmission loss influence factor corresponding to each preset transmission influence characteristic value interval in the database to obtain the transmission loss influence factor of the cooling water pipeline. The transmission loss influence factor of the cooling water pipeline is used to correct the influence of cooling water during pipeline transmission.

[0025] As a preferred technical solution, the step of comprehensively analyzing the required cooling water flow rate of the forging chamber and the transmission loss influencing factors of the cooling water pipeline to obtain the total cooling water flow rate of the forging chamber specifically includes:

[0026] Based on the transmission loss influence factor of the cooling water pipeline, the cooling water replenishment flow rate corresponding to each preset transmission loss influence factor interval in the database is mapped and matched to obtain the cooling water replenishment flow rate of the cooling water pipeline. This flow rate is then added to the cooling water flow rate required by the forging chamber to obtain the total cooling water flow rate required by the forging chamber.

[0027] As a preferred technical solution, the processing obtains real-time water flow characteristic values ​​of the cooling water pipeline, and the specific processing conditions are as follows:

[0028] ;

[0029] in, This represents the real-time water flow characteristic value of the cooling water pipeline. For the cooling water pipeline No. Real-time water temperature at each location, For the cooling water pipeline No. Real-time flow rate at each point, For the cooling water pipeline No. Real-time water pressure at each location, For the cooling water pipeline No. The expected water temperature at each point For the cooling water pipeline No. The expected flow rate at each point For the cooling water pipeline No. The expected water pressure at each point, Water temperature weighting factor, As the flow rate weighting factor, Water pressure weighting factor, Numbering of cooling water pipeline locations. , This represents the total number of cooling water pipe locations. The `softplus` function is a built-in function in Python. .

[0030] In addition, the present invention also provides a method for controlling efficient circulating cooling water in vacuum isothermal forging, comprising:

[0031] S1. At the initial moment of starting vacuum isothermal forging, the unobstructedness of the cooling water pipeline is checked, and the unobstructedness of the cooling water pipeline is obtained. If the unobstructedness of the cooling water pipeline is unqualified, an early warning is sent to the management terminal.

[0037] Compared with the prior art, the embodiments of the present invention have at least the following beneficial effects:

[0038] (1) This invention provides a high-efficiency circulating cooling water system for vacuum isothermal forging. By sending a pure-tone sinusoidal sound wave signal with pre-set parameters to the cooling water pipe and receiving the transmission signal parameters of the pure-tone sinusoidal sound wave, the smoothness of the cooling water pipe is analyzed. This method does not require machine shutdown for inspection and will not interfere with the normal operation of the cooling system. Furthermore, sound waves have the characteristic of fast propagation speed, which can quickly obtain information on the smoothness of the pipe, improve detection efficiency, and avoid accidents caused by blockage of the cooling water pipe.

[0041] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0043] Figure 2 This is a schematic diagram of the method flow of the present invention. Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0046] Please see Figure 1 As shown, an embodiment of the present invention provides a high-efficiency circulating cooling water system for vacuum isothermal forging, comprising:

[0047] The initial self-test module is used to check the patency of the cooling water pipeline at the initial moment of starting vacuum isothermal forging and obtain the patency test result. If the patency test result is unqualified, an early warning is sent to the management terminal. If the patency test result is qualified, an automatic forging start signal is generated and sent to the switch controller to control the start of vacuum isothermal forging.

[0048] The specific process for checking the patency of the cooling water pipes is as follows:

[0049] A sound wave transmitter installed at the inlet of the cooling water pipe sends a pure tone sinusoidal sound wave signal with a preset frequency and amplitude to the cooling water pipe. After receiving the pure tone sinusoidal sound wave signal, a sound wave receiver installed at the outlet of the cooling water pipe obtains the transmission signal parameters of the pure tone sinusoidal sound wave, including the velocity, frequency, maximum amplitude, and waveform function of the pure tone sinusoidal sound wave signal. Based on the transmission signal parameters of the pure tone sinusoidal sound wave, the unobstructedness assessment value of the cooling water pipe is obtained through analysis and processing. The unobstructedness assessment value of the cooling water pipe is used to assess whether there is a blockage in the cooling water pipe.

[0050] It should be explained that the velocity, frequency, maximum amplitude, and waveform function of a pure-tone sinusoidal sound wave signal play the following roles in assessing the unobstructedness of cooling water pipes:

[0051] In pipeline patency testing, the velocity of sound waves can help determine the properties (such as gas, liquid, or solid) and state (such as temperature and pressure) of the medium within the pipeline. Sound waves travel at different speeds in different media; by measuring changes in the velocity of sound waves, it is possible to infer whether a blockage exists in the pipeline.

[0052] Frequency selection is crucial for pipe inspection. Different frequencies of sound waves are sensitive to different types and sizes of defects in pipes. For example, low-frequency sound waves can penetrate thicker materials or bypass larger obstacles, while high-frequency sound waves are more easily reflected by small defects. By analyzing the frequency variations of the reflected sound waves, obstacles or defects in the pipe can be identified.

[0053] In pipeline inspection, the maximum amplitude of a sound wave is related to its propagation distance and energy loss. When a sound wave encounters an obstacle in the pipeline, some of its energy is reflected back. The degree of amplitude attenuation can be used to assess the pipeline's patency.

[0054] Waveform function analysis can provide detailed information about the propagation of sound waves in a pipe. Ideally, the emitted sound wave is a sinusoidal waveform, but when it encounters a defect in the pipe, the reflected waveform may be distorted. By comparing the emitted and received waveforms, the type and location of the defect in the pipe can be identified.

[0055] It should be noted that, in this embodiment of the invention, the phase angle of the transmitted pure tone sinusoidal sound wave signal is 0, and the sound wave period is 1.

[0056] The analysis and processing yields an assessment value for the unobstructed flow of the cooling water pipes, specifically including:

[0057] ;

[0058] ;

[0059] ;

[0060] ;

[0061] in, This is an assessment value for the unobstructed flow of cooling water pipes. The speed of a pure-tone sinusoidal sound wave signal. The frequency of a pure tone sinusoidal sound wave signal. The maximum amplitude of a pure-tone sinusoidal sound wave signal. The waveform function of a pure-tone sinusoidal sound wave signal. The speed preset for transmitting a pure tone sine wave signal. The frequency preset for transmitting a pure tone sine wave signal. The amplitude is preset for transmitting a pure-tone sine wave signal. The `softplus` function is a pre-defined waveform function for transmitting a pure-tone sinusoidal sound signal, where `t` is time. `softplus` is a built-in function in Python. .

[0062] It's important to note that there's a correlation between the parameters of a pure-tone sinusoidal sound wave signal: velocity, frequency, maximum amplitude, and waveform function. Frequency determines the periodicity of the sound wave, that is, the number of times the waveform function repeats per unit time. The higher the frequency, the shorter the period of the sound wave, and the more times the waveform function repeats per unit time. The waveform function is determined by both the frequency and amplitude of the sound wave; therefore, changes in frequency directly affect the shape of the waveform function. Maximum amplitude determines the intensity or energy of the sound wave. In a waveform function graph, amplitude represents the height of the peaks and troughs. The larger the amplitude, the stronger the energy of the sound wave, and the larger the range of fluctuation of the waveform function on the vertical axis. The velocity of the sound wave affects the time it takes for the sound wave to travel through the medium, but it does not directly affect the shape of the waveform function. However, if the sound wave encounters different media or obstacles during propagation, changes in velocity may cause distortion of the waveform function, such as reflection, refraction, or attenuation. Frequency is inversely proportional to wavelength, while velocity is the product of frequency and wavelength.

[0063] The obtained cooling water pipeline unobstructedness test results specifically include:

[0064] If the unobstructedness assessment value of the cooling water pipeline is less than or equal to the unobstructedness assessment threshold, the unobstructedness test result of the cooling water pipeline is determined to be unqualified, and an early warning is sent to the management terminal.

[0065] If the unobstructedness assessment value of the cooling water pipeline is greater than the unobstructedness assessment threshold, the unobstructedness test result of the cooling water pipeline is deemed qualified, and an automatic forging start signal is generated to the switch controller to control the start of vacuum isothermal forging.

[0066] The smoothness assessment threshold is processed as follows: In a specific embodiment, the smoothness assessment threshold is set directly in the database during the development of the vacuum isothermal forging high-efficiency circulating cooling water system involved in this embodiment of the invention. There are various methods for setting the smoothness assessment threshold, such as obtaining it through statistical analysis, including statistically analyzing the smoothness assessment values ​​under historical high smoothness conditions and averaging the smoothness assessment values ​​obtained multiple times to obtain the smoothness assessment threshold, or experts setting the threshold by judging the boundary between high and low smoothness assessment values ​​through corresponding historical data, thereby adjusting the threshold.

[0067] The sensing and monitoring module is used to acquire the real-time temperature of the forging chamber and send it to the data processing module, and at the same time monitor the real-time water flow parameters in the cooling water pipes and send them to the data processing module.

[0068] The real-time water flow parameters monitored in the cooling water pipeline specifically include:

[0069] Several integrated sensors that are equidistantly distributed inside the cooling water pipe are referred to as point-integrated sensors.

[0070] Real-time water flow parameters in the cooling water pipes are monitored by integrating sensors at various points. These real-time water flow parameters include real-time water temperature, real-time flow velocity, and real-time water pressure at each point.

[0071] Real-time water temperature at each point refers to the water temperature at various points in the cooling water pipes. Water temperature is a key indicator for measuring cooling efficiency. If the water temperature is too high, it may indicate insufficient cooling capacity, leading to equipment overheating. If the water temperature is too low, it may indicate overcooling, affecting energy efficiency.

[0072] Real-time flow velocity at each point refers to the speed at which cooling water flows through the pipes. Flow velocity directly affects the heat exchange efficiency of the cooling water. Excessive flow velocity may cause pipe wear, while insufficient flow velocity may lead to inadequate cooling.

[0073] Real-time water pressure at various points refers to the pressure of cooling water at each point in the pipeline. Water pressure is the driving force that ensures the flow of cooling water. Insufficient water pressure may cause slow water flow, affecting the cooling effect. Excessive water pressure may damage the pipeline.

[0074] The external environment monitoring module is used to acquire external environmental parameters of the cooling water pipeline, comprehensively analyze and process them to obtain the external environmental impact correction factor, and send it to the data processing module.

[0075] The acquisition of external environmental parameters of the cooling water pipeline, and the comprehensive analysis and processing to obtain external environmental impact correction factors, specifically include:

[0076] The external environmental parameters of the cooling water pipeline include the real-time external temperature, real-time external humidity, and real-time external air pressure at each screening point.

[0077] Real-time external temperature refers to the temperature of the environment surrounding the cooling water pipes. External temperature affects the heat exchange efficiency of the cooling system. If the external temperature is high, the heat dissipation effect may decrease, leading to an increase in cooling water temperature and affecting cooling efficiency.

[0078] Real-time external humidity refers to the humidity level of the environment surrounding the cooling water pipes. Humidity affects the thermal conductivity of the air and the evaporation efficiency of the cooling tower. High humidity may reduce the cooling effect of the cooling tower because humid air has a lower heat dissipation capacity than dry air.

[0079] Real-time external air pressure refers to the air pressure surrounding the cooling water pipes. Changes in air pressure affect the boiling point of cooling water. Under low air pressure, the boiling point of water decreases, which affects the operating efficiency of the cooling system.

[0080] External temperature, humidity, and air pressure verification values ​​are extracted from the database and analyzed with external environmental parameters to obtain external environmental impact correction factors, specifically including:

[0081] ;

[0082] in, External environmental influence correction factor For the first Real-time external temperature at each screening point For the first Real-time external humidity at each screening point For the first Real-time external air pressure at each screening point This is the external temperature calibration value. This is the external humidity calibration value. This is the external air pressure verification value. Number the screening points. , Let be the total number of screening points, and e be a natural constant.

[0083] It should be noted that the external environmental parameters of the cooling water pipeline, including real-time external temperature, real-time external humidity, and real-time external air pressure at each screening point, are correlated. This correlation primarily manifests in their combined effect on the heat exchange process and cooling efficiency of the cooling system. Humidity affects the evaporative cooling effect. In high-temperature and high-humidity environments, the evaporative cooling efficiency decreases because the air already contains more moisture, reducing the cooling water's evaporation potential. There is an inverse relationship between temperature and air pressure. Generally, as temperature increases, air pressure decreases, and vice versa. Changes in air pressure affect the boiling point of cooling water. At low air pressure, the boiling point of water decreases, which may affect cooling. At lower air pressures, the amount of water vapor that the air can hold decreases, thus increasing relative humidity. Changes in air pressure may affect humidity measurements; therefore, the influence of air pressure needs to be considered when analyzing humidity data.

[0084] The data processing module is used to obtain the required cooling water flow rate of the forging chamber based on the real-time temperature analysis of the forging chamber, and to obtain the transmission loss influence factor of the cooling water pipeline based on the real-time water flow parameters of the cooling water pipeline and the external environmental influence correction factor. The total required cooling water flow rate of the forging chamber is obtained by comprehensively analyzing the required cooling water flow rate of the forging chamber and the transmission loss influence factor of the cooling water pipeline.

[0085] The process involves analyzing the real-time temperature of the forging chamber to obtain the required cooling water flow rate, and then processing the real-time flow parameters of the cooling water pipes and external environmental influence correction factors to obtain the transmission loss influence factor of the cooling water pipes. Specifically, this includes:

[0086] Based on the real-time temperature of the forging chamber, a comparison is made with the set cooling temperature. If the real-time temperature of the forging chamber is less than or equal to the set cooling temperature, a minimum speed signal is sent to the closed-loop pumping unit to make the closed-loop pumping unit run at the minimum speed. The difference between the real-time temperature of the forging chamber and the set cooling temperature is calculated to obtain the required heating temperature difference. Based on the required heating temperature difference, a mapping and matching is performed with the heater power adjustment values ​​corresponding to each required heating temperature difference range pre-stored in the database to obtain the power adjustment value of the heater in the forging chamber, and the heater power is adjusted accordingly.

[0087] If the real-time temperature of the forging chamber is greater than the set cooling temperature, the difference is calculated to obtain the cooling temperature difference. The cooling temperature difference is then mapped and matched with the cooling water flow rate corresponding to each cooling temperature difference range stored in the database to obtain the required cooling water flow rate for the forging chamber.

[0088] The real-time water flow parameters of the cooling water pipeline are processed to obtain the real-time water flow characteristic value of the cooling water pipeline. Combined with the smoothness assessment value of the cooling water pipeline and the external environmental influence correction factor, the transmission influence characteristic value of the cooling water pipeline is obtained. The transmission influence characteristic value of the cooling water pipeline is mapped and matched with the transmission loss influence factor corresponding to each preset transmission influence characteristic value interval in the database to obtain the transmission loss influence factor of the cooling water pipeline. The transmission loss influence factor of the cooling water pipeline is used to correct the influence of cooling water during pipeline transmission.

[0089] The process obtains real-time water flow characteristic values ​​of the cooling water pipeline, and the specific processing conditions are as follows:

[0090] The expected water flow parameters at each point of the cooling water pipeline are extracted from the database, including the expected water temperature, expected flow velocity, and expected water pressure at each point. The expected water flow parameters at each point of the cooling water pipeline are the water flow parameters that minimize the loss of the cooling water pipeline after the cooling water system is simulated during development.

[0091] The real-time water flow parameters at various points in the cooling water pipeline are compared and analyzed with the expected water flow parameters to obtain the real-time water flow characteristic values ​​of the cooling water pipeline. The specific process is as follows:

[0092] ;

[0093] in, This represents the real-time water flow characteristic value of the cooling water pipeline. For the cooling water pipeline No. Real-time water temperature at each location, For the cooling water pipeline No. Real-time flow rate at each point, For the cooling water pipeline No. Real-time water pressure at each location, For the cooling water pipeline No. The expected water temperature at each point For the cooling water pipeline No. The expected flow rate at each point For the cooling water pipeline No. The expected water pressure at each point, Water temperature weighting factor, As the flow rate weighting factor, Water pressure weighting factor, Numbering of cooling water pipeline locations. , This represents the total number of cooling water pipe locations. The `softplus` function is a built-in function in Python. , where e is the natural constant.

[0094] It should be noted that the values ​​of the water temperature weighting factor, flow velocity weighting factor, and water pressure weighting factor are all between 0 and 1, and satisfy the following conditions: The water temperature weight factor is a preset influence factor corresponding to the real-time water flow characteristic value of the cooling water pipe in the database. It represents the degree of influence of water temperature on the real-time water flow characteristic value of the cooling water pipe. The flow velocity weight factor is a preset influence factor corresponding to the real-time water flow characteristic value of the cooling water pipe in the database. It represents the degree of influence of flow velocity on the real-time water flow characteristic value of the cooling water pipe. The water pressure weight factor is a preset influence factor corresponding to the real-time water flow characteristic value of the cooling water pipe in the database. It represents the degree of influence of water pressure on the real-time water flow characteristic value of the cooling water pipe. When using it, the water temperature weight factor, flow velocity weight factor and water pressure weight factor can be directly obtained from the database. Their correspondence is a preset mapping relationship. For example, the real-time water flow characteristic value of the cooling water pipe forms a mapping set with the water temperature weight factor, flow velocity weight factor and water pressure weight factor respectively. The real-time water flow parameters are input into the mapping set to obtain the water temperature weight factor, flow velocity weight factor and water pressure weight factor. The mapping relationship is one-to-one.

[0095] It should be noted that the real-time water flow parameters within the cooling water pipes, including real-time water temperature, real-time flow velocity, and real-time water pressure at various points, are correlated. Water temperature directly affects cooling efficiency. If the water temperature is too high, the flow velocity may need to be increased to improve cooling efficiency, i.e., increasing the water flow speed to enhance heat exchange capacity. At a given flow velocity, the water temperature will change with the heat exchange process. Increasing the flow velocity may result in a more uniform temperature distribution, but it may also increase frictional losses in the pipes. Changes in water temperature affect water density, which in turn affects water pressure. Generally, as water temperature increases, water density decreases, potentially leading to a drop in water pressure. Increased water temperature may cause the cooling water circulation pump to provide higher pressure to maintain the same flow velocity. In fluid mechanics, the relationship between flow velocity and water pressure can be described by the Darcy-Weisbach equation, which states that flow velocity is proportional to the pressure difference across the pipe. Increased flow velocity leads to increased frictional losses within the pipe, requiring higher water pressure to overcome these losses and maintain the desired flow velocity. Water temperature, flow rate, and water pressure collectively determine the heat exchange efficiency of a cooling system. Increasing the flow rate can improve the heat exchange rate, but it may also increase the water pressure requirement. Increased flow rate leads to increased pipe resistance, which typically requires higher water pressure to maintain. These three parameters need to operate in a balanced state to ensure the stability and reliability of the cooling system.

[0096] In another embodiment of the invention, if the real-time water flow characteristic value of the cooling water pipeline is greater than or equal to the real-time water flow characteristic threshold, it is determined to be an abnormal operation, an alarm is sent to the management terminal, and a minimum speed signal is simultaneously sent to the closed-loop pumping unit to make the closed-loop pumping unit operate at the minimum speed. If the real-time water flow characteristic value of the cooling water pipeline is less than the real-time water flow characteristic threshold, it is determined to be a normal operation. The real-time water flow characteristic value of the cooling water pipeline is statistically analyzed and processed in conjunction with the unobstructed flow assessment value of the cooling water pipeline and the external environmental influence correction factor to obtain the transmission influence characteristic value of the cooling water pipeline. The specific process includes:
