[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] It should be noted that, in the description of the present invention, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. The terms "first," "second," etc., in the present invention are used to distinguish similar objects, and are not used to describe a particular order or precedence.

[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] An embodiment of the present invention provides a control method for a liquid-cooled integral proportional valve control system. The method is described in detail in conjunction with the execution flow of the control method for the liquid-cooled integral proportional valve control system.

[0030] Specifically, before introducing the embodiments of the present invention, we first introduce the problem of water leakage in the liquid cooling system in the related art. The liquid cooling integral proportional valve is a key component in the liquid cooling system, responsible for accurately adjusting the flow and pressure of the liquid. However, during the operation of the liquid cooling system, water leakage is a common and serious hidden danger. Once water leakage occurs, if it cannot be controlled in a timely and effective manner, it may cause equipment damage, short circuit, and even cause a safety accident.

[0031] Because some control devices in the relevant technology cannot quickly and accurately close the liquid-cooled integral proportional valve and cut off the relevant electrical connections when facing a water leakage alarm, and after the water leakage problem is solved, there is also a lack of relevant control for reopening the liquid-cooled integral proportional valve and the electrical switch. Therefore, it is impossible to meet the needs of different users for manual or automatic operation. Based on the above-mentioned problems, an embodiment of the present invention provides a liquid-cooled integral proportional valve control system that can reliably monitor water leakage and accurately control the liquid-cooled integral proportional valve and the relevant electrical switch, so as to achieve precise control of the closing speed of the liquid-cooled integral proportional valve and the disconnection of the electrical switch.

[0032] Specifically, Figure 1 A flow chart of a control method for a liquid-cooled integral proportional valve control system provided by an embodiment of the present invention.

[0033] like Figure 1 As shown, in the control method of the liquid-cooled integral proportional valve control system, the liquid-cooled integral proportional valve control system is provided with an interface unit and a liquid-cooled integral proportional valve, wherein the interface unit is provided with a multi-way electrical switch, wherein the following steps are included:

[0034] In step S101, it is determined whether a water leakage alarm signal from an interface unit is received.

[0035] Specifically, if Figure 2 As shown, the liquid-cooled integral proportional valve control system of the embodiment of the present invention is mainly composed of the following parts, including: an interface unit, a control module, a power module, a human-computer interaction interface and a housing, wherein, as Figure 3 As shown, the interface unit is responsible for electrically connecting with sensors (such as water leakage sensors) and electrical equipment (such as cooling pumps, solenoid valves, etc.) of the external liquid cooling system. The interface unit provides multi-way electrical switches (such as 8-way electrical switches) to control switch quantity access, including 4 normally open interfaces NO1-N04 (Normally Open) (including normally open interface 1, normally open interface 2, normally open interface 3 and normally open interface 4) and 4 normally closed interfaces NC1-NC4 (Normally Closed) (including normally closed interface 1, normally closed interface 2, normally closed interface 3 and normally closed interface 4) and a water leakage sensor interface. The liquid cooling integral proportional valve control system is connected to various components in the liquid cooling system through the above 4 normally open interfaces and 4 normally closed interfaces. At the same time, it can adapt to various liquid cooling system layouts and control requirements, providing diverse options for connecting external equipment. The specific connection method can be configured according to actual application requirements.

[0036] For example, if Figure 3As shown, the four normally open interfaces (NO1-NO4) can be connected to devices that are powered on during normal operation but need to be powered off immediately when a water leakage alarm occurs, such as the enable signal line of the motor control circuit of the cooling pump, the drive power line of the solenoid valve, and the power input end of other electrical equipment that requires interlocking control, thereby controlling the flow direction of the coolant through the interface unit; the four normally closed interfaces (NC1-NC4) ​​can be connected to protection circuits or alarm circuits that remain closed under normal circumstances but need to be disconnected under specific circumstances (such as water leakage alarm or system failure), such as the control line connected to the sound and light alarm, which is disconnected and triggers the alarm when a water leakage occurs, and the enable signal line connected to certain safety protection circuits, which is disconnected when a water leakage occurs and stops the operation of related equipment; the water leakage sensor interface is used to receive the water leakage alarm signal from the water leakage sensor installed in the liquid cooling system. The interface is compatible with the output signals of various types of water leakage sensors (such as switch signals, analog signals).

[0037] It should be noted that the above interfaces can use standard industrial connectors, such as terminal blocks, aviation plugs, etc., to ensure the reliability of the connection. Each interface should have clear markings to facilitate user wiring.

[0038] Furthermore, if Figure 4As shown in the figure, the control module is the core part of the liquid-cooled integral proportional valve control system. It integrates the hardware and software for implementing the control logic and fuzzy PID control algorithm. It is mainly responsible for receiving and processing the signals from the interface unit, and outputting the control signals to the liquid-cooled integral proportional valve and the electrical switch according to the preset control logic and fuzzy PID control algorithm. The control module can be implemented based on a high-performance microcontroller or programmable logic controller. Among them, the hardware part: a high-performance industrial-grade MCU (Microcontroller Unit) can be selected, such as the ARMCortex-M3 series, which has input and output ports GPIO (General-Purpose Input / Output, general input and output ports), analog-to-digital converter ADC (Analog-to-Digital Converter, analog-to-digital converter, used to receive analog sensor signals), timer and communication interface (used to communicate with the host computer or other control systems); Software part: The control program can be developed in C language, and the program needs to implement the following functions: (1) Signal acquisition and processing: Regularly read the leakage alarm signal of the leakage sensor interface, and perform necessary filtering and processing on the received leakage alarm signal; (2) Fuzzy PID control algorithm implementation: Fuzzification, fuzzy reasoning and defuzzification processing are performed based on the received leakage alarm signal, and the fuzzy PID control algorithm is used to control the closing speed of the liquid-cooled integral proportional valve and the disconnection of the electrical switch; (3) Liquid-cooled integral proportional valve control: Generate the corresponding output according to the fuzzy PID control algorithm. (4) Electrical switch control: According to the water leakage alarm signal and the interface type, the corresponding control signal (high level or low level) is output to control the opening and closing of the normally open interface and the normally closed interface; (5) Manual control logic implementation: Respond to the manual operation button on the human-computer interaction interface to realize the manual opening and closing of the liquid cooling integral proportional valve and the electrical switch; (6) Automatic control logic implementation: According to the preset recovery conditions (such as the water leakage sensor signal returns to normal, the status of related equipment is restored, etc.) and time intervals, the opening operation of the liquid cooling integral proportional valve and the electrical switch is automatically executed; (7) Status monitoring and management: Monitor the operating status of the liquid cooling integral proportional valve control system itself and the liquid cooling system, and perform necessary fault diagnosis and management.

[0039] Furthermore, the power module provides a stable working power supply for the entire liquid-cooled integral proportional valve control system. The power module needs to adapt to the power requirements of the industrial environment and have functions such as overvoltage and overcurrent protection to ensure the stable operation of the device.

[0040] Furthermore, the human-computer interaction interface may include indicator lights, display screens, and operation buttons, etc., for displaying the working status and alarm information of the liquid-cooled integral proportional valve control system, and allowing the user to perform manual operations (such as manually opening the liquid-cooled integral proportional valve and electrical switch).

[0041] Furthermore, the housing is used to protect internal electronic components and provide a certain level of protection to adapt to the environmental requirements of the liquid cooling system control center.

[0042] Therefore, based on the various components of the above-mentioned cold integral proportional valve control system, the liquid-cooled integral proportional valve and the liquid-cooled integral proportional valve control system of the related electrical switch can be accurately controlled, thereby achieving precise control of the closing speed of the liquid-cooled integral proportional valve and the disconnection of the electrical switch. The following will be explained in detail based on the specific implementation steps.

[0043] In step S102, if a water leakage alarm signal is received, the closing speed of the liquid-cooled integral proportional valve is calculated based on the water leakage alarm signal using a preset fuzzy algorithm, and the first control instruction of the liquid-cooled integral proportional valve is output. At the same time, based on the interface type of the interface unit and the water leakage alarm signal, the second control instruction of the multi-way electrical switch is output.

[0044] The preset fuzzy algorithm can be selected by those skilled in the art according to actual testing requirements and is not specifically limited here.

[0045] Specifically, first, after the cold integral proportional valve control system receives the water leakage alarm signal sent by the water leakage sensor interface, it immediately starts a precise control process based on a preset fuzzy algorithm (such as a fuzzy PID control algorithm). The algorithm can dynamically adjust the PID control parameters according to the real-time water leakage situation and the system operation status, and after calculating the closing speed of the liquid-cooled integral proportional valve, output the first control instruction of the liquid-cooled integral proportional valve, that is, quickly and accurately close the liquid-cooled integral proportional valve, and output the second control instruction of the multi-way electrical switch according to the interface type of the interface unit and the water leakage alarm signal, that is, disconnect the corresponding electrical switch according to the interface type and the water leakage alarm signal (wherein the normally open interface outputs a low level disconnection, and the normally closed interface outputs a high level disconnection), thereby effectively avoiding equipment damage and safety accidents caused by water leakage.

[0046] According to one embodiment of the present invention, a preset fuzzy algorithm is used to calculate the closing speed of the liquid-cooled integral proportional valve, including: obtaining the current water leakage error and error change rate of the liquid cooling system; fuzzy processing the current water leakage error and error change rate through preset fuzzy rules, and outputting the target adjustment amount of the PID parameters; adjusting the PID parameters according to the target adjustment amount, and controlling the closing speed of the liquid-cooled integral proportional valve according to the adjusted PID parameters.

[0047] According to one embodiment of the present invention, the current water leakage error and error change rate of the liquid cooling system are obtained, including: obtaining the current water leakage output value of the water leakage sensor device in the liquid cooling system and the baseline value of the no-leakage situation; calculating the current water leakage error of the liquid cooling system based on the current water leakage output value and the baseline value of the no-leakage situation; performing differential calculation on the current water leakage error to obtain the error change rate.

[0048] Specifically, in the process of using a preset fuzzy algorithm to accurately control the leakage process, first, the current leakage output value of the leakage sensor device in the liquid cooling system and the baseline value of the no-leakage situation are obtained, and the current leakage error (e(k)) of the liquid cooling system is calculated based on the current leakage output value and the baseline value of the no-leakage situation, and then the current leakage error is differentially calculated to obtain the error change rate (ec(k)), where the current leakage error (e(k)) represents the deviation between the current actual leakage situation and the expected no-leakage state, and the deviation can be quantified by the signal strength of the leakage sensor or the change amplitude of related system parameters. For example, the voltage value or current value output by the leakage sensor can be compared with a preset threshold to obtain an error signal; the error change rate (ec(k)) represents the change rate of the current leakage error (e(k)) per unit time, reflecting the development trend of the leakage situation.

[0049] Secondly, if Figure 5 As shown, in order to improve the performance of the liquid-cooled integral proportional valve control system, the embodiment of the present invention needs to further perform fuzzy processing on the current water leakage error (e(k)) and the error change rate (ec(k)) based on the calculated current water leakage error (e(k)) and the error change rate (ec(k)) through preset fuzzy rules (for example, in the form of "IF...AND...THEN..."), such as defining how to dynamically adjust the PID parameters according to the current water leakage error (e(k)) and the error change rate (ec(k)) to achieve fast response, smooth transition and high-precision control. Then, after fuzzy processing of the current water leakage error and the error change rate, the target adjustment amount of the PID parameters is output, so that the PID parameters are adjusted according to the target adjustment amount, and the closing speed of the liquid-cooled integral proportional valve is controlled according to the adjusted PID parameters, so that good performance can be maintained even when the parameters of the liquid-cooled integral proportional valve control system change.

[0050] Therefore, based on the fuzzy processing of the current water leakage error and the error change rate and the reasoning using the preset fuzzy rules, the performance of the liquid-cooled integral proportional valve control system can be significantly improved.

[0051] According to one embodiment of the present invention, the current water leakage error and the error change rate are fuzzy processed by preset fuzzy rules, including: fuzzy processing the current water leakage error and the error change rate; outputting the initial adjustment amount of the PID parameter based on the fuzzified current water leakage error and the error change rate, and fuzzy processing the initial adjustment amount based on the preset fuzzy rules to obtain a fuzzy value of the initial adjustment amount; defuzzifying the fuzzy value of the initial adjustment amount to obtain a target adjustment amount of the PID parameter.

[0052] According to one embodiment of the present invention, fuzzy processing is performed on the current water leakage error and the error change rate, including: constructing at least one current water leakage error fuzzy set and at least one error change rate fuzzy set; mapping the current water leakage error to the error fuzzy set corresponding to the parameter properties of the current water leakage error according to the parameter properties of the current water leakage error, and mapping the water leakage change rate to the error change rate fuzzy set corresponding to the parameter properties of the water leakage change rate according to the parameter properties of the water leakage change rate; and determining a first membership function of each current water leakage error fuzzy set and a second membership function of each error change rate fuzzy set.

[0053] According to one embodiment of the present invention, fuzzy processing is performed on the initial adjustment amount based on preset fuzzy rules, including: constructing a fuzzy set of the initial adjustment amount; mapping the initial adjustment amount to the fuzzy set, and determining a third membership function of the fuzzy set.

[0054] Specifically, if Figure 5As shown, in the process of fuzzifying the current leakage error and the error change rate by using preset fuzzy rules, first, at least one current leakage error fuzzy set and at least one error change rate fuzzy set are constructed, and according to the parameter properties of the current leakage error, the current leakage error is mapped to the error fuzzy sets corresponding to the parameter properties of the current leakage error. In this embodiment, the following error fuzzy sets are defined for the current leakage error (e(k)) and the error change rate (ec(k)) (which can be adjusted according to actual applications), mainly including: the fuzzy set of the current leakage error (e(k)): {Negative Large (NB), Negative Small (NS), Zero (ZO), Positive Small (PS), Positive Large (PB)}, and the fuzzy set of the error change rate (ec(k)): {Negative Large (N B), negative small (NS), zero (ZO), positive small (PS), positive large (PB)}, among which, negative large (NB) indicates that the current leakage error is decreasing rapidly (the leakage is improving), negative small (NS) indicates that the current leakage error is decreasing slowly, zero (ZO) indicates that the current leakage error is basically unchanged (the leakage is stable), positive small (PS) indicates that the current leakage error is increasing slowly (the leakage is beginning to worsen), and positive large (PB) indicates that the error is increasing rapidly (the leakage is rapidly worsening). Each fuzzy set corresponds to a membership function, which is used to indicate the degree to which the input variable belongs to the fuzzy set. Therefore, the first membership function of each current leakage error fuzzy set and the second membership function of each error change rate fuzzy set can be determined. The value range of the first membership function and the second membership function is usually between [0, 1]. The specific shapes of the first membership function and the second membership function can be selected according to actual needs, such as triangle, trapezoid or Gaussian.

[0055] For example, for the current water leakage error (e(k)), if the value of (e(k)) is close to 0, that is, the current water leakage error is basically unchanged, then its first membership function may be mainly concentrated in the "zero (ZO)" set; if the value of (e(k)) is large and positive, then its first membership function may be mainly concentrated in the "positive large (PB)" set.

[0056] Secondly, if Figure 5As shown, based on the fuzzified current water leakage error and error change rate, the initial adjustment amount of the PID parameters is output. The initial adjustment amount of the PID parameters includes the proportional gain adjustment amount ΔKp, the integral time adjustment amount ΔKi, and the differential time adjustment amount ΔKd. Similar to the fuzzy processing of the current water leakage error and error change rate mentioned above, these adjustment amounts also need to be fuzzified and mapped to the corresponding fuzzy sets. For example, the following fuzzy sets can be defined for the initial adjustment amount of each PID parameter: fuzzy set of proportional gain adjustment amount (ΔKp): {negative large (NB), negative small (NS), zero (ZO), positive small (PS), positive large (PB)}; fuzzy set of integral time adjustment amount (ΔKi): {negative large (NB), negative small (NS), zero (ZO), positive small (PS), positive large (PB)}; differential time adjustment amount (ΔKd) The fuzzy set is: {Negative Large (NB), Negative Small (NS), Zero (ZO), Positive Small (PS), Positive Large (PB)}. The initial adjustment amount is then mapped to the corresponding fuzzy set, and the third membership function of the fuzzy set is determined. The initial adjustment amount is then fuzzy processed based on the preset fuzzy rule to obtain the fuzzy value of the initial adjustment amount. For example, if (e(k)) is PB AND (ec(k)) is PS THEN ΔKpis NB, ΔKi is NB, ΔKd is NS. That is, when the current leakage error (e(k)) is positive and large, and the error change rate (ec(k)) is positive and small, the proportional gain ΔKp is negative and large, the integral time ΔKi is negative and large, and the differential time ΔKd is negative and small. The fuzzy value of the initial adjustment amount is then defuzzified and converted into an accurate control amount. For example, the fuzzy output obtained by fuzzy inference is converted into a specific value (for example, if ΔKp is PB → after defuzzification, ΔKp = +0.4 → The controller increases the proportional gain to speed up the response speed), and then obtains the target adjustment amount of the PID parameter. Common defuzzification methods include the center of gravity method, the weighted average method, etc. In the embodiment of the present invention, the center of gravity method can be used to calculate the center of gravity of each output fuzzy set, and the weighted average is performed according to the membership degree to obtain the final accurate adjustment amount, that is, the target adjustment amount of the PID parameter.

[0057] Therefore, by fuzzifying the current leakage error and error change rate, the fuzzy value of the initial adjustment amount of the PID parameter is obtained, which can effectively filter out noise interference, avoid malfunction due to small fluctuations, and provide a basis for subsequent fuzzy reasoning, so that the controller can make reasonable control judgments according to the current state. The fuzzy value of the initial adjustment amount is then defuzzified, that is, the fuzzy conclusion obtained by fuzzy reasoning is converted into a specific numerical value, and a control signal that can be used by the actual actuator is generated, completing the mapping from the "fuzzy world" to the "real world".

[0058] According to one embodiment of the present invention, the PID parameters are adjusted according to the target adjustment amount, and the closing speed of the liquid-cooled integral proportional valve is controlled according to the adjusted PID parameters, including: adding the target adjustment amount of the PID parameters and the PID parameters to obtain new PID parameters; and controlling the closing speed of the liquid-cooled integral proportional valve according to the new PID parameters.

[0059] Specifically, after obtaining the target adjustment amount of the PID parameter, it is necessary to adjust the PID parameter according to the target adjustment amount. For example, the target adjustment amount of the PID parameter is added to the PID parameter to obtain a new PID parameter, and the closing speed of the liquid-cooled integral proportional valve is controlled according to the adjusted PID parameter, which is mainly expressed as: Kp(k) = Kp(k-1) + ΔKp; Ki(k) = Ki(k-1) + ΔKi; Kd(k) = Kd(k-1) + ΔKd.

[0060] For example, when a water leak is severe (large errors and rapid changes), the fuzzy PID controller may increase Kp and Kd and decrease Ki to speed up the valve closing speed and suppress overshoot. At the same time, the fuzzy PID controller will also adjust the response speed and logic of the electrical switch disconnection according to the severity of the water leak.

[0061] Therefore, the PID parameters can be dynamically adjusted according to the real-time water leakage situation, thereby realizing online tuning of the PID controller, so that the liquid-cooled integral proportional valve control system can maintain good control performance under different working conditions.

[0062] According to one embodiment of the present invention, based on the interface type of the interface unit and the water leakage alarm signal, a second control instruction of the multi-way electrical switch is output, including: if the interface type of the interface unit is a normally open interface, then based on the water leakage alarm signal, a first level signal is sent to the normally open interface, and a disconnect instruction of the normally open interface is generated based on the first level signal; if the interface type of the interface unit is a normally closed interface, then based on the water leakage alarm signal, a second level signal is sent to the normally closed interface, and a disconnect instruction of the normally closed interface is generated based on the second level signal, wherein the first level signal and the second level signal are opposite signals to each other.

[0063] Specifically, after receiving the water leakage alarm signal, it is also necessary to output a second control instruction of the multi-way electrical switch based on the interface type of the interface unit and the water leakage alarm signal to control the closing action of the multi-way electrical switch.

[0064] Specifically, the present invention can give a corresponding water leakage signal output based on the level of the water leakage alarm signal according to the type of the interface unit. If the interface type of the interface unit is a normally open interface, a first level signal (i.e., a low level signal) is sent to the normally open interface based on the water leakage alarm signal to generate a disconnect instruction for the normally open interface based on the first level signal; if the interface type of the interface unit is a normally closed interface, a second level signal (i.e., a high level signal) is sent to the normally closed interface based on the water leakage alarm signal to generate a disconnect instruction for the normally closed interface based on the second level signal. Therefore, when a water leakage occurs, different level signals can be used to control the normally open interface and the normally closed interface to be shut down, thereby preventing the coolant from flowing further and expanding the leakage range. At the same time, since multi-way electrical switches are usually connected to multiple key components, when a water leakage occurs, these switches can be uniformly controlled to realize operations such as equipment linkage shutdown, fault isolation, and starting a safe mode, thereby realizing a safety linkage protection mechanism.

[0065] In step S103 , the liquid-cooled integral proportional valve is controlled to close at a target speed based on the first control instruction, and the multi-way electrical switch is controlled to close based on the second control instruction.

[0066] Specifically, based on the closing speed of the liquid-cooled integral proportional valve calculated based on the above embodiment, a first control instruction of the liquid-cooled integral proportional valve is further output to control the liquid-cooled integral proportional valve to close at the target speed based on the first control instruction. At the same time, based on the interface type of the interface unit and the water leakage alarm signal output, a second control instruction of the multi-way electrical switch is obtained to control the multi-way electrical switch to close based on the second control instruction. Therefore, when a water leakage occurs, the liquid-cooled integral proportional valve and related electrical switch connections can be quickly and accurately closed, thereby improving the safety and reliability of the liquid-cooled integral proportional valve control system.

[0067] According to one embodiment of the present invention, after controlling the liquid-cooled integral proportional valve to close at a target speed based on a first control instruction and controlling the multi-way electrical switch to close based on a second control instruction, it also includes: judging whether a water leakage alarm release instruction is received from the interface unit; if a water leakage alarm release instruction is received, judging whether the liquid-cooled integral proportional valve meets the preset opening condition; if the liquid-cooled integral proportional valve meets the preset opening condition, controlling the liquid-cooled integral proportional valve and the multi-way electrical switch to open based on a preset opening mode.

[0068] The preset start-up conditions may be selected by those skilled in the art according to actual test requirements and are not specifically limited here.

[0069] Specifically, after the water leakage is resolved, in order to avoid the problems such as decreased cooling efficiency, delayed equipment restart, and temperature control imbalance caused by the failure of the liquid-cooled integral proportional valve and the multi-way electrical switch to open in time, the embodiment of the present invention needs to open the connection between the liquid-cooled integral proportional valve and the related electrical switches in time after the water leakage is resolved, so as to effectively avoid various negative effects caused by the failure of the liquid-cooled integral proportional valve and the multi-way electrical switch to open in time, and ensure the continuous and stable operation of the liquid-cooled integral proportional valve control system.

[0070] Specifically, if Figure 6 As shown, if the water leakage condition is resolved, the interface unit will receive a water leakage alarm release command from the water leakage sensor interface, and then send the water leakage alarm release command to the liquid cooling integral proportional valve control system. After the liquid cooling integral proportional valve control system receives the water leakage alarm release command, it determines whether the liquid cooling integral proportional valve meets the preset opening conditions. This determination may mainly include processes such as the water leakage alarm release command, ambient environmental conditions, equipment status, and preliminary startup tests. For example, upon receiving the water leakage alarm release command, checking environmental parameters ((coolant temperature: 20°C - normal range), (ambient humidity: 45%RH - suitable), (system pressure: 2 bar (standard working pressure)))), verifying equipment status (e.g., all electrical switches are in the off state and can be safely reset, the cooling pump and fan are ready to receive the start command, and the control system is online and displays normal), and performing a pre-test startup (sending a valve opening command to 10%, observing that the valve response time is 2 seconds (in compliance with specifications), and the flow meter shows a stable increase in flow without abnormal fluctuations). If the above conditions are met, it can be determined that the liquid cooling integral proportional valve meets the preset opening conditions.

[0071] Furthermore, if the liquid-cooled integral proportional valve meets the preset opening conditions, the liquid-cooled integral proportional valve and the multi-way electrical switch are controlled to open based on the preset opening mode. For example, a target flow or pressure value can be set, and then the fuzzy PID control algorithm is used to adjust according to the deviation between the actual value and the target value to control the liquid-cooled integral proportional valve and the multi-way electrical switch to open.

[0072] Therefore, after the water leakage is resolved and the liquid-cooled integral proportional valve meets the preset opening conditions, the liquid-cooled integral proportional valve and the multi-way electrical switch are controlled to open, thereby ensuring that the liquid cooling system can quickly return to normal working conditions, enhancing the reliability and stability of the liquid-cooled integral proportional valve control system, and reducing unnecessary energy consumption.

[0073] According to one embodiment of the present invention, the opening of the liquid-cooled integral proportional valve and the multi-way electrical switch is controlled based on a preset opening mode, including: if the preset opening mode is a manual mode, the opening button is manually operated to open the liquid-cooled integral proportional valve based on the water leakage situation, and a second level signal is sent to the normally open interface, and a first level signal is sent to the normally closed interface at the same time, so as to generate an opening instruction for the normally open interface according to the second level signal, and generate an opening instruction for the normally closed interface based on the first level signal.

[0074] Specifically, if Figure 6 As shown, in the process of controlling the opening of the liquid-cooled integral proportional valve and the multi-way electrical switch based on the preset opening mode, the liquid-cooled integral proportional valve and the multi-way electrical switch can be opened in manual mode and automatic mode. If the preset opening mode is manual mode, the opening button is manually operated to open the liquid-cooled integral proportional valve based on the actual situation of water leakage, and a second level signal is sent to the normally open interface, and a first level signal is sent to the normally closed interface at the same time, so as to generate an opening instruction of the normally open interface according to the second level signal, and generate an opening instruction of the normally closed interface based on the first level signal. That is to say, after the liquid-cooled integral proportional valve meets the preset opening condition, an opening instruction is sent to the liquid-cooled integral proportional valve, and according to the button pressed by the user, the normally open interface is controlled to output a high level to close it, and the normally closed interface is controlled to output a low level to restore it to a closed state.

[0075] Therefore, in manual mode, users can operate buttons according to actual conditions to control the opening of valves and electrical interfaces respectively. In certain specific situations (such as equipment maintenance and commissioning stages), automated control may not be able to fully adapt to actual needs. At this time, manual control provides a higher degree of freedom, allowing users to take immediate measures when encountering emergencies without having to wait for the response of the automated system, thereby bringing significant flexibility, safety and reliability advantages to the system.

[0076] According to one embodiment of the present invention, the liquid-cooled integral proportional valve and the multi-way electrical switch are controlled to open based on a preset opening mode, and also include: if the preset opening mode is an automatic mode, determining whether the liquid-cooled integral proportional valve and the multi-way electrical switch meet the preset recovery conditions; if the preset recovery conditions are met, generating a third control instruction for the liquid-cooled integral proportional valve and a fourth control instruction for the multi-way electrical switch; controlling the liquid-cooled integral proportional valve to open according to the third control instruction, and controlling the multi-way electrical switch to open according to the fourth control instruction.

[0077] According to one embodiment of the present invention, the liquid-cooled integral proportional valve is controlled to open according to a third control instruction, and the multi-way electrical switch is controlled to open according to a fourth control instruction, including: based on a first preset interval duration, the liquid-cooled integral proportional valve is controlled to open according to the third control instruction, and after the liquid-cooled integral proportional valve is opened, based on a second preset interval duration, a second level signal is sent to the normally open interface to generate an opening instruction of the normally open interface according to the second level signal, and the normally open interface is controlled to open according to the opening instruction of the normally open interface; after the normally open interface is opened, a first level signal is sent to the normally closed interface based on the third preset interval duration to generate an opening instruction of the normally closed interface according to the first level signal, and the normally closed interface is controlled to open according to the opening instruction of the normally closed interface.

[0078] Among them, the preset recovery condition, the first preset interval duration, the second preset interval duration and the third preset interval duration can all be selected by those skilled in the art according to actual test requirements and are not specifically limited here.

[0079] Specifically, if the preset opening mode is automatic mode, it is first necessary to determine whether the liquid-cooled integral proportional valve and the multi-way electrical switch meet the preset recovery conditions. For example, it can be set that the recovery conditions are met only when the signal of the water leakage sensor returns to a normal level for a period of time and the status of related key equipment (which can be judged by the sensor connected to the normally closed interface) also returns to normal. When all conditions are met, the control module will first wait for a preset delay time to ensure system stability, and then execute in sequence according to the preset order: based on the first preset interval length, a third control instruction is sent to the liquid-cooled integral proportional valve to control the opening of the liquid-cooled integral proportional valve, and then a fourth control instruction of the multi-way electrical switch is generated to control the opening of the multi-way electrical switch according to the fourth control instruction. For example, after the liquid-cooled integral proportional valve is opened, it waits for the second preset interval length, outputs a high-level signal to the normally open interface to close it, and after waiting for the third preset interval length, outputs a low-level signal to the normally closed interface to restore it to a closed state.

[0080] Therefore, in automatic mode, the liquid-cooled integral proportional valve control system can intelligently judge and open the integral proportional valve and electrical switch in sequence according to the preset recovery conditions and time intervals, thereby realizing the automatic recovery operation of the liquid-cooled integral proportional valve control system, thereby enhancing the safety and reliability of the system, while optimizing the system recovery process and shortening downtime.

[0081] In summary, based on the above specific discussion, the present invention can achieve the following beneficial effects:

[0082] (1) Significantly improved the safety of the liquid cooling system: By quickly and accurately closing the integral proportional valve and disconnecting the relevant electrical connections (including normally open and normally closed interfaces) when a water leakage alarm is detected, equipment damage, electrical short circuits, and possible safety accidents caused by liquid leakage are effectively avoided, thereby significantly improving the overall safety of the liquid cooling system.

[0083] (2) Provides a more flexible system integration solution: The system is equipped with 8-way electrical switch control switch quantity access, including 4 normally open interfaces and 4 normally closed interfaces. The flexible interface design can adapt to different liquid cooling system layouts and control requirements, making it convenient for users to connect various external devices according to actual application scenarios, providing a wider range of system integration possibilities.

[0084] (3) A more intelligent control strategy is implemented: the fuzzy PID control algorithm is used to control the valve closing and electrical switch disconnection process when a water leakage alarm is generated. The control parameters can be dynamically adjusted according to the real-time water leakage situation and system status. Compared with traditional fixed threshold control or simple switch control, it has faster response speed and higher control accuracy, which improves the system's ability to cope with emergencies.

[0085] (4) Provides a convenient and flexible operation mode after the alarm is lifted: The present invention supports both manual and automatic modes to reopen valves and electrical switches. Users can choose the appropriate operation mode according to actual needs and system recovery conditions. This not only ensures the flexibility of operation, but also enables the system to automatically resume operation after the preset conditions are met, reducing the need for manual intervention.

[0086] (5) Improved system reliability and stability: Through intelligent control and flexible interface design, the present invention can more effectively manage the status of the liquid cooling system under normal operation and abnormal conditions, reducing the system failure rate caused by problems such as water leakage, thereby improving the overall reliability and stability of the liquid cooling system.

[0087] According to the control method of the liquid-cooled integral proportional valve control system proposed in an embodiment of the present invention, upon receiving a water leakage alarm signal, a preset fuzzy algorithm is used to calculate the closing speed of the liquid-cooled integral proportional valve and output its first control instruction. At the same time, based on the interface type of the interface unit and the water leakage alarm signal, a second control instruction for the multi-way electrical switch is output, so as to control the liquid-cooled integral proportional valve to close at the target speed based on the first control instruction, and to control the multi-way electrical switch to close based on the second control instruction. This solves the technical problems of being unable to quickly and accurately close the valve and cut off the related electrical connections when a water leakage alarm occurs, and at the same time, lacking a flexible valve and electrical switch restart mechanism after the water leakage problem is solved. The PID algorithm is used to analyze the leakage error and error change rate, and dynamically adjust the PID controller parameters to achieve precise control of the valve closing speed and electrical switch disconnection.

[0088] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method.
