DETAILED DESCRIPTION

[0019] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0022] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0023] With the rapid development of information technology, data centers, as the core infrastructure supporting various information applications, are increasing in size and density. Liquid-cooled servers have been widely used in data centers due to their efficient heat dissipation solutions. However, with the high degree of integration of liquid-cooled servers, higher requirements are placed on the volume and sensitivity adjustment functions of liquid leakage detection devices.

[0024] In the process of realizing the present invention, the inventors found that the prior art has at least the following technical problems: the small-volume liquid leakage detection devices currently on the market generally have a single function and do not have a sensitivity adjustment function, which limits their adaptability in different application scenarios.

[0025] In addition, although the general leakage detection device can achieve sensitivity adjustment by setting a dip switch, this method requires additional corresponding components, which increases the volume and cost of the leakage detection device and is not suitable for highly integrated scenarios with strict volume requirements.

[0026] Therefore, the present invention provides a method for detecting liquid leakage to solve the above-mentioned problem.

[0027] Please refer to Figure 1 , which is a flow chart of a method for liquid leakage detection provided by an embodiment of the present invention, applied to a liquid leakage detection device, comprising the following steps: Step S01, when a trigger signal is received through the first interface, the resistance value of the external component is obtained through the second interface.

[0028] In this embodiment, the external component may include a liquid leakage detection rope or a sensitivity matcher, wherein the resistance value of the sensitivity matcher is adjustable, and its use is to adjust the sensitivity of the liquid leakage detection device. By changing the resistance value of the sensitivity matcher, the maximum value of the resistance at which the liquid leakage detection device determines that a liquid leakage has occurred can be changed, thereby adapting to different detection environments and requirements. For example, in situations where higher requirements are placed on liquid leakage detection, the sensitivity of the detection device can be increased by lowering the liquid leakage threshold of the sensitivity matcher, so that even a tiny liquid leakage can be detected in time.

[0029] The leak detection rope is a component directly responsible for detecting leaks. It is usually placed in places where leaks may occur, such as the liquid cooling system of a server. When liquid contacts the leak detection rope, its resistance value will change due to its resistance characteristics. This change can be captured by the detection device and used to determine whether a leak has occurred.

[0030] In this embodiment, the first interface is used to receive a trigger signal, and the trigger signal is used to trigger the leakage detection device to power on or enter a working state; the second interface is used to communicate with an external component to obtain the resistance value of the external component. In this embodiment, the sensitivity matcher and the leakage detection rope share the same interface by designing, so that the user can adjust or determine the detection sensitivity of the leakage detection device by adjusting the resistance value of the sensitivity matcher, thereby adapting to different detection environments and needs. In this way, the leakage detection device can perform leakage detection more flexibly and accurately, reduce false alarms and missed alarms, and improve the reliability of detection.

[0031] Step S02, determining a leakage threshold value according to the resistance value of the sensitivity matcher.

[0032] In this embodiment, the leakage threshold is the maximum resistance of the leakage detection rope when the leakage detection device confirms that a leakage has occurred. When the resistance value measured by the leakage detection device is less than the preset leakage threshold, it means that a leakage may have occurred, and the leakage detection device will trigger an alarm or take other preset countermeasures. Since the small-volume leakage detection devices currently on the market generally have a single function and do not have a sensitivity adjustment function; and the general leakage detection device requires additional corresponding devices, which increases the volume and cost, and is not suitable for highly integrated scenarios with strict volume requirements.

[0033] Therefore, this embodiment uses a detachable sensitivity matcher to determine the leakage threshold, allowing the user to flexibly adjust the sensitivity of the leakage detection device according to specific application scenarios and needs. This design enables the leakage detection device to adapt to a variety of different environmental conditions, improving its versatility and applicability. This solves the problem of single function of small-volume leakage detection devices on the market. At the same time, through the design of sharing the same interface, the structure of the leakage detection device is simplified, so that when connecting the leakage detection rope for leakage detection, there is no need to additionally connect the sensitivity matcher, thereby reducing the volume and complexity of the device, which is particularly suitable for highly integrated scenarios with strict volume requirements. In this way, the leakage detection device can perform leakage detection more flexibly and accurately, reduce false alarms and missed alarms, and improve the reliability of detection.

[0034] In some embodiments, as mentioned in step S02, determining the leakage threshold according to the resistance value of the sensitivity matcher may specifically include the following steps: Step S11, determining whether the sensitivity gear matching of the leakage detection device is completed within a preset matching time.

[0035] If yes, execute step S12; if no, execute step S13.

[0036] Please refer to Figure 2 , is a schematic diagram of an operating time axis of a liquid leakage detection device provided by an embodiment of the present invention. Figure 2 During the leakage detection stage), if there is abnormal interference, causing the detected resistance value to jump, there is a probability that the sensitivity gear matching process of the leakage detection device will be triggered.

[0037] Therefore, in order to prevent the sensitivity adjustment of the leakage detection device from being triggered by mistake, the leakage detection device in this embodiment will Figure 2In the sensitivity matching stage, it is checked whether the sensitivity of the device has been successfully adjusted to the correct gear corresponding to the resistance value of the external component. At the same time, by executing step S11, it can also be ensured that the leakage detection device can accurately complete the determination of the leakage threshold within a limited time. If the matching is completed within the preset time, the leakage detection device will execute step S12 to determine the leakage threshold according to the gear matching result; if it is not completed, the leakage detection device will execute step S13 to determine the leakage threshold according to the default sensitivity gear.

[0038] Step S12, determining the leakage threshold value according to the gear matching result.

[0039] Step S13, determining the leakage threshold value according to the default sensitivity level.

[0040] In some embodiments, the default sensitivity level may be a pre-set common sensitivity level, or may be the sensitivity level at which the last match was successful, which is not specifically limited in this embodiment.

[0041] Please refer to Figure 3 , is a flow chart of the sensitivity gear matching of a leakage detection device provided by an embodiment of the present invention. Figure 3 As shown, the gear position matching process of the sensitivity gear position of the liquid leakage detection device mentioned in step S11 may specifically include the following steps: Step S21, determining the interval range of the matching interval corresponding to each sensitivity level in the liquid leakage detection device.

[0042] In this embodiment, a specific resistance value range is set for each possible sensitivity level in the sensitivity adjustment mechanism of the leakage detection device, and this range is the matching interval. Each sensitivity level corresponds to a specific resistance value interval. When the resistance value obtained by the external component falls within a specific interval, the leakage detection device identifies it as the corresponding sensitivity level. This step is to ensure that the device can automatically adjust its sensitivity according to different resistance value inputs, so as to adapt to different detection environments and requirements. In this way, the leakage detection device can flexibly adjust its detection sensitivity without adding additional hardware, thereby improving the accuracy and reliability of detection.

[0043] In some embodiments, please refer to Figure 4 , is a schematic diagram of a matching interval corresponding to a sensitivity level provided in an embodiment of the present invention. Figure 4As shown, R_0 is the leakage threshold, R_M is the maximum value of the leakage threshold, R1_MIN to R1_MAX is the matching interval corresponding to the first level of sensitivity, and R_a is the set value corresponding to the first level of sensitivity; R2_MIN to R2_MAX is the matching interval corresponding to the second level of sensitivity, and R_b is the set value corresponding to the second level of sensitivity; R3_MIN to R3_MAX is the matching interval corresponding to the third level of sensitivity, and R_c is the set value corresponding to the third level of sensitivity; R4_MIN to R4_MAX is the matching interval corresponding to the fourth level of sensitivity, and R_d is the set value corresponding to the fourth level of sensitivity.

[0044] In this embodiment, the maximum value R_M of the leakage threshold is the maximum resistance value of the leakage detection rope under normal working conditions. In this embodiment, the resistance values ​​of the matching intervals corresponding to the sensitivity gears are all greater than the maximum resistance value of the leakage detection rope under normal working conditions, in order to avoid triggering the sensitivity gear matching process of the leakage detection device when the leakage detection rope is in working condition.

[0045] Step S22, continuously acquiring the resistance value of the external component through the second interface.

[0046] In this embodiment, the resistance value is continuously read from the connected external component (such as a sensitivity matcher or a leakage detection rope) through the second interface. This continuous reading process is to monitor the resistance change of the external component in real time, which can reflect whether the sensitivity setting of the leakage detection device needs to be adjusted. In this way, the leakage detection device can dynamically determine its sensitivity level according to the resistance value of the external component, so as to adapt to different detection environments and conditions.

[0047] In some embodiments, the resistance value of the external component can be calculated by acquiring the voltage value and the current value of the external component.

[0048] Step S23, determining whether the resistance value falls within the same matching interval twice in a row; If yes, execute step S24; if no, return to step S22 to continuously obtain the resistance value of the external component through the second interface.

[0049] In this embodiment, it is determined whether the resistance value falls into the same preset matching interval twice in a row. The purpose of this step is to verify the stability of the resistance value and ensure that the resistance value does not accidentally fall into a certain matching interval due to instantaneous interference or noise. If the resistance value is within the same matching interval twice in a row, it means that the resistance value of the external component has stabilized. At this time, step S24 can be executed to determine whether the number of times the resistance value falls into the same matching interval in a row exceeds the preset matching number to confirm the matching of the sensitivity level.

[0050] In some embodiments, if the resistance value does not fall into the same matching interval twice in a row, the leakage detection device will return to step S22 and continue to obtain a new resistance value through the second interface until the continuity requirement is met. This method helps to improve the accuracy and reliability of the sensitivity matching process, avoid mismatching due to accidental factors, and ensure that the leakage detection device can work at the correct sensitivity level.

[0051] Step S24, determining whether the number of times the resistance value continuously falls into the same matching interval exceeds a preset matching number.

[0052] If yes, execute step S25; if no, return to execute step S22 to continuously obtain the resistance value of the external component through the second interface.

[0053] In this embodiment, the sensitivity level of the liquid leakage detection device is confirmed by checking whether the resistance value of the external component obtained through the second interface falls into the same matching interval for multiple consecutive times. If the number of times the resistance value falls into the same matching interval continuously does not exceed the preset number of matches, the liquid leakage detection device will return to step S22 and continue to obtain new resistance values ​​to collect more data points to ensure the accuracy of the match. This process helps to eliminate mismatching caused by instantaneous fluctuations or interference, thereby improving the reliability of the sensitivity level determination.

[0054] If the number of times the resistance value continuously falls into the same matching interval exceeds the preset matching number, it means that the stability of the resistance value has been verified, and the leakage detection device will execute step S25 to set the sensitivity level corresponding to this matching interval as the current sensitivity level of the leakage detection device. This design ensures that the leakage detection device can correctly adjust its sensitivity within a stable resistance value range, thereby providing accurate leakage detection in practical applications.

[0055] Step S25, determining the sensitivity level corresponding to the same matching interval as the sensitivity level of the liquid leakage detection device.

[0056] On the basis of the above embodiments, in some embodiments, the leakage threshold mentioned in step S12 is determined according to the gear matching result, which can be specifically: The preset value corresponding to the sensitivity level of the liquid leakage detection device is determined according to the preset corresponding relationship, and the liquid leakage threshold is determined as the preset value.

[0057] For example, if the number of times that the resistance value continuously falls into the matching interval R1_MIN to R1_MAX exceeds a preset matching number, the leakage threshold is set to a set value R_a corresponding to a level of sensitivity.

[0058] Based on the above technical solution, this embodiment provides an automated method for determining the sensitivity level of the liquid leakage detection device without manual intervention, thereby improving the reliability and accuracy of the liquid leakage detection device.

[0059] In some embodiments, the minimum resistance value of the sensitivity matcher can be set to be greater than the maximum resistance value of the leakage detection rope, so as to distinguish whether the external component is a sensitivity matcher or a leakage detection rope. For example, when the resistance value obtained by the leakage detection device through the second interface exceeds the preset value, it is determined that the sensitivity gear matching stage has been entered at this time, and the sensitivity gear matching is performed according to the resistance value; when the resistance value obtained by the leakage detection device through the second interface is less than the preset value, it is determined that the leakage detection stage has been entered at this time, and the leakage detection is performed according to the resistance value, so as to distinguish between the sensitivity gear matching stage and the leakage detection stage.

[0060] On the basis of the above embodiments, in some embodiments, the visualization of the sensitivity level of the liquid leakage detection device can be realized by executing the following steps: Determine the corresponding display signal according to the sensitivity level of the leakage detection device; The display signal is sent to the display component of the liquid leakage detection device, so that the display component displays the sensitivity level of the liquid leakage detection device.

[0061] In this embodiment, the display component may include a display screen or an indicator light. Taking the display component as an LED indicator light as an example, the number of times the LED indicator light flashes when powered on can be set to indicate different gears. Specifically, 3 seconds after power-on, the LED indicator light will flash a corresponding number of times according to the sensitivity gear. For example, if the LED indicator light flashes once, it means that the current setting is the first gear, and if it flashes twice, it means the second gear, and so on. This design provides a simple and direct way to identify the sensitivity gear of the leakage detection device without complicated operations or additional display devices.

[0062] This embodiment provides an intuitive way to communicate the current sensitivity setting of the leakage detection device to the user. By converting the sensitivity level into an easy-to-understand display signal and displaying it on the display component, the user can quickly understand the current working status of the device and ensure that it operates as expected.

[0063] Step S03, performing leakage detection according to the leakage threshold and the resistance value of the leakage detection rope.

[0064] In this embodiment, after determining the leakage threshold, the leakage detection device uses this threshold as a judgment standard to detect whether leakage has occurred. The leakage threshold is a specific level of resistance value. When the detected resistance value is less than this level, the device will consider that leakage has occurred. This threshold is dynamically set according to the resistance value when the external component is a sensitivity matcher to adapt to different detection environments and sensitivity requirements. In this way, the leakage detection device can more accurately identify leakage events, reduce false alarms and missed alarms, and thus improve the reliability and effectiveness of detection.

[0065] In some embodiments, as mentioned in step S03, the leakage detection is performed according to the leakage threshold and the resistance value of the leakage detection rope, which can be specifically: Obtain the resistance value of the leakage detection rope through the second interface; Determine whether the resistance value is less than the leakage threshold; If yes, leakage is confirmed.

[0066] In this embodiment, the leakage detection device monitors the resistance change of the leakage detection rope in real time. Once the resistance value is lower than the preset leakage threshold, the leakage event can be quickly confirmed and corresponding measures can be taken. This not only improves the response speed and accuracy of leakage detection, but also helps to prevent damage that may be caused by leakage in a timely manner, thereby enhancing the safety and reliability of the system. In addition, by simplifying the detection process, the operation complexity is reduced, the user's operation convenience is improved, and at the same time, false alarms and missed alarms are reduced, thereby improving the overall performance of the detection system.

[0067] If the detected resistance value is lower than the leakage threshold, the device will immediately confirm the leakage event and take appropriate measures, such as sounding an alarm or shutting down related systems, to prevent further damage caused by the leakage. This real-time monitoring and rapid response capability significantly improves the efficiency and accuracy of leakage detection, reduces the possibility of false alarms and missed alarms, and thus enhances the safety and reliability of the entire system.

[0068] Based on the above technical solution, when the embodiment of the present invention receives a trigger signal through the first interface, the resistance value of the external component is obtained through the second interface; the leakage threshold is determined according to the resistance value of the sensitivity matcher; and leakage detection is performed according to the leakage threshold and the resistance value of the leakage detection rope. The present invention determines the leakage threshold by utilizing the resistance value of a detachable sensitivity matcher to achieve precise adjustment of the leakage detection sensitivity to adapt to different detection requirements and environmental conditions. At the same time, by sharing the same interface design, the structure of the leakage detection device is simplified, so that when connecting the leakage detection rope for leakage detection, there is no need to additionally connect a sensitivity matcher, thereby reducing the size and complexity of the device. In addition, the detachable sensitivity matcher design makes maintenance and upgrading easier, and users can quickly replace or adjust components as needed, reducing costs and maintenance difficulties.

[0069] Please refer to Figure 5 , is a schematic diagram of the structure of a liquid leakage detection device provided by an embodiment of the present invention, the liquid leakage detection device may include a liquid leakage detection plate, a sensitivity matcher and a liquid leakage detection rope, wherein: The liquid leakage detection board includes a first interface, a second interface, a display component, and a controller, and the first interface, the second interface, and the display component are respectively connected to the controller for communication; The sensitivity matcher is detachably connected to the second interface of the liquid leakage detection board; The liquid leakage detection rope is detachably connected to the second interface of the liquid leakage detection plate; The controller includes a processor and a memory connected to the processor for communication, wherein the memory is used to store at least one instruction, and when the instruction is loaded and executed by the processor, the method for detecting liquid leakage as described above is implemented.

[0070] This embodiment provides a modular and flexibly configurable leakage detection solution. The leakage detection board is equipped with a second interface for connecting external components, such as a sensitivity matcher or a leakage detection rope. This design enables the device to be quickly adjusted according to different application scenarios and requirements.

[0071] When the user needs to adjust the sensitivity, he only needs to connect the sensitivity matcher to the first interface of the leakage detection board and select a suitable resistance in the sensitivity matcher. The controller will automatically set the corresponding leakage threshold according to the detected resistance.

[0072] When the user needs to perform a liquid leakage detection, he only needs to connect the liquid leakage detection rope to the first interface of the liquid leakage detection board, and the controller will automatically compare the detected resistance with the liquid leakage threshold to achieve liquid leakage detection.

[0073] The cooperation of the processor and memory in the controller enables the device to execute preset instructions and realize automatic sensitivity adjustment and leakage detection process. This design improves the accuracy and efficiency of leakage detection, while reducing the complexity and cost of sensitivity adjustment operation, making the leakage detection device suitable for various environments, including data centers and liquid-cooled server systems that are sensitive to space and cost.

[0074] The first interface in this embodiment is used to connect to the power supply & communication line, and can receive a trigger signal sent externally.

[0075] In some embodiments, the liquid leakage detection board may further include: A power source connected to the first interface, the second interface, the display assembly and the controller.

[0076] In this embodiment, by setting a power supply, it is possible to ensure that all components of the leakage detection device can obtain a stable power supply. The existence of the power supply component makes the entire system more independent and self-sufficient, without relying on an external power supply, thereby improving the portability and installation flexibility of the device. In addition, centralized power management helps to optimize energy use, ensure that all components operate in the best condition, and also facilitate maintenance and troubleshooting. This comprehensive power supply design enhances the reliability and practicality of the leakage detection device, making it more suitable for various application environments, including those where there are restrictions on power access or portability is required.

[0077] In some embodiments, the sensitivity matcher may be a resistor selector. Figure 6 , is a structural schematic diagram of a resistance selector provided in an embodiment of the present invention.

[0078] In this embodiment, the leakage detection device adjusts its sensitivity level by selecting different resistance values. The introduction of the resistance selector enables the leakage detection device to flexibly adapt to different detection environments and requirements without adding additional hardware components. Through the resistance selector, the user can select the most suitable resistance value according to the actual application scenario, thereby setting the sensitivity of leakage detection. This embodiment not only simplifies the sensitivity adjustment process, but also improves the applicability and user-friendliness of the device. The use of the resistance selector enables the leakage detection device to provide accurate leakage detection function while maintaining a compact size, which is particularly important for application scenarios with limited space.

[0079] In some embodiments, the sensitivity matcher may specifically be a signal generator.

[0080] In this embodiment, the sensitivity matcher matches the sensitivity level by sending a PWM (pulse width modulation) signal or a specific waveform voltage. The leakage detection device can determine its sensitivity level by receiving the duty cycle or frequency of the PWM signal through the second interface.

[0081] In some embodiments, the leakage detection device may also match the sensitivity level by monitoring the change trend or change rate of the voltage.

[0082] This embodiment provides a digital solution, replacing the traditional analog resistance output method, making the sensitivity adjustment more accurate and flexible. This digital matching method reduces the interference that the analog signal may receive during the transmission process, not only improving the accuracy of leakage detection, but also improving the response speed and reliability of the system.

[0083] This embodiment provides a liquid cooling system, including a liquid leakage detection device as described in any one of the above items, and its execution method and beneficial effects are similar, which will not be repeated here.

[0084] It should be noted that although the above describes the various steps in a specific order, it does not mean that the various steps must be executed in the above specific order. In fact, some of these steps can be executed concurrently or even in a different order as long as the required functions can be achieved.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
