Description

Technical Field

[0001] This invention relates to the field of leakage detection technology, and in particular to a method, apparatus, equipment and medium for setting leakage alarm thresholds. Background Technology

[0002] Currently, the convenient application and development of the internet have provided diversified information services to hundreds of millions of users, but they have also brought severe challenges to server manufacturers. With the upgrading of server CPUs (Central Processing Units) and configurations, server power consumption is getting higher and higher. Traditional air cooling can no longer meet the temperature control requirements of data centers. Therefore, heat dissipation designs such as cold plates, immersion liquid cooling, and air cooling combined with water cooling are receiving increasing attention from server manufacturers.

[0003] Liquid-cooled servers typically employ a combination of liquid-cooled heatsinks, liquid-cooled pipes, and liquid-cooled pumps to dissipate heat from critical areas and high-power components such as the CPU, memory, and PCIe (PCI-Express, a high-speed serial computer expansion bus standard) expansion cards. The liquid-cooled pipes contain different types of coolant, which is circulated and cooled by the liquid-cooled pump. While liquid cooling is highly efficient, a leak can cause short circuits in components on the PCB (Printed Circuit Board), resulting in irreversible damage to the server. Therefore, leak detection is crucial in liquid-cooled servers.

[0004] See Figure 1 The diagram illustrates an existing leak detection design. The leak detection line has 4-pin connectors at both ends. Pin 1 of these connectors is the leak fault detection indicator pin, connected to the V+ input (positive input) of a voltage comparator. An alarm threshold is set by using voltage divider resistors (R4 and R5) at the V- input (negative input) of the voltage comparator. The voltage comparator operates as follows: when the voltage at the positive input (V+) is greater than the voltage at the negative input (V-), the comparator output is high (Vout = 3.3V in the diagram); when the voltage at the positive input is less than the voltage at the negative input, the comparator output is low (Vout = 0V in the diagram).

[0005] The alarm threshold V- = 3.3 × R5 × (R4 + R5), typically R4 = 4.7 kΩ, R5 = 10 kΩ, i.e., V- = 2.24 V; the leak detection voltage V+ = 3.3 × (R3 / / R7) × ((R3 / / R7) + R2); where R3 / / R7 = R3 × R7 / (R3 + R7).

[0006] When pins 2 and 3 of the leak detection line are shorted internally, and no leak occurs, the equivalent impedance R7 between terminals A and B is large. At this time, V+ ≈ 3.3V, which is greater than V-, and a leak alarm will not be triggered. When a leak occurs, terminals A and B are short-circuited, and the equivalent impedance R7 changes and decreases. When the leak is small, the equivalent impedance R7 is relatively large. Although V+ is divided, it is still greater than V-, and a leak alarm will not be triggered. When the leak is large, R7 decreases sharply, causing V+ to be less than V-, thus triggering a leak alarm. The equivalent impedance R7 of the leak detection line is affected by factors such as the type of leak detection line, the type of coolant, and the amount of leak. The leak detection sensitivity varies under different coolants and different heat dissipation configurations. Therefore, the leak detection sensitivity is usually modified by changing the resistance value of the external pull-up resistor R2 to adapt to the leak detection requirements of different liquid cooling configurations.

[0007] However, the current method for modifying the sensitivity of leakage detection requires modifying the electronic components, namely the resistance value of resistor R2, and the setting method is extremely fixed and inflexible.

[0008] In summary, how to more flexibly detect leaks in different liquid cooling configurations is a problem that urgently needs to be solved. Summary of the Invention

[0009] In view of this, the purpose of this invention is to provide a method, apparatus, device, and medium for setting a leakage alarm threshold, which can more flexibly detect leakage in different liquid cooling configurations. The specific solution is as follows:

[0010] In a first aspect, this application discloses a method for setting a leakage alarm threshold, applied to a substrate management controller of a leakage detection system. The leakage detection system further includes a voltage comparator, a digital-to-analog converter chip connected between the substrate management controller and the negative input terminal of the voltage comparator, and a complex programmable logic device connected to the substrate management controller. The method includes:

[0011] Determine the leakage alarm threshold for each liquid cooling configuration;

[0012] Obtain the target liquid cooling configuration that needs to be detected, as input by the user;

[0013] The target leakage alarm threshold corresponding to the target liquid cooling configuration is determined from the leakage alarm thresholds corresponding to each of the liquid cooling configurations.

[0014] The target leakage alarm threshold is stored in the complex programmable logic device (CPLD). When performing leakage detection, the substrate management controller reads the target leakage alarm threshold from the CPLD and sends it to the negative input terminal of the voltage comparator via the digital-to-analog converter (DAC) chip as the negative voltage value. The voltage comparator then compares the positive voltage value at the positive input terminal with the negative voltage value to determine whether to issue a leakage alarm. The positive voltage value is calculated by the leakage detection system based on the target liquid cooling configuration and leakage situation.

[0015] Optionally, the step of obtaining the target liquid cooling configuration currently to be detected input by the user; determining the target leakage alarm threshold corresponding to the target liquid cooling configuration from the leakage alarm thresholds corresponding to each liquid cooling configuration; and storing the target leakage alarm threshold in the complex programmable logic device includes:

[0016] Obtain the target liquid cooling configuration that needs to be detected, as input by the user;

[0017] The target leakage alarm threshold corresponding to the target liquid cooling configuration is determined from the leakage alarm thresholds corresponding to each of the liquid cooling configurations.

[0018] The target leakage alarm threshold is stored in the complex programmable logic device;

[0019] Read the reference leakage alarm threshold in the complex programmable logic device and compare the reference leakage alarm threshold with the target leakage alarm threshold;

[0020] If the comparison is consistent, the setting of the leakage alarm threshold is terminated;

[0021] If the comparison is inconsistent, the process jumps to the step of obtaining the target liquid cooling configuration to be detected by the user input, so as to re-store the target leakage alarm threshold to the complex programmable logic device, until the comparison is consistent and the setting of the leakage alarm threshold ends.

[0022] Optionally, storing the target leakage alarm threshold in the complex programmable logic device includes:

[0023] The target leakage alarm threshold is stored in the flash memory area of ​​the complex programmable logic device.

[0024] Optionally, the leakage detection system may also include a circuit board device;

[0025] Accordingly, determining the leakage alarm threshold for each liquid cooling configuration includes:

[0026] The circuit board is read to determine the leakage alarm threshold corresponding to each liquid cooling configuration.

[0027] Optionally, the step of reading the board to determine the leakage alarm threshold corresponding to each liquid cooling configuration includes:

[0028] Read the board device to obtain the board device identifier;

[0029] The target item corresponding to the board device identifier is determined, and the leakage alarm threshold corresponding to each liquid cooling configuration under the target item is obtained from the firmware of the baseboard management controller.

[0030] Optionally, the baseboard management controller and the digital-to-analog converter chip, as well as the complex programmable logic device and the baseboard management controller, are connected via a bidirectional two-wire synchronous serial bus.

[0031] Optionally, when the positive voltage value is less than the negative voltage value, the voltage comparator sends a leakage alarm to the substrate management controller through its output terminal.

[0032] Secondly, this application discloses a leakage alarm threshold setting device applied to a substrate management controller of a leakage detection system. The leakage detection system further includes a voltage comparator, a digital-to-analog converter chip connected between the substrate management controller and the negative input terminal of the voltage comparator, and a complex programmable logic device connected to the substrate management controller. The device includes:

[0033] The first threshold determination module is used to determine the leakage alarm threshold corresponding to each liquid cooling configuration.

[0034] The configuration acquisition module is used to acquire the target liquid cooling configuration that needs to be detected, as input by the user.

[0035] The second threshold determination module determines the target leakage alarm threshold corresponding to the target liquid cooling configuration from the leakage alarm thresholds corresponding to each liquid cooling configuration.

[0036] A threshold storage module is used to store the target leakage alarm threshold in the complex programmable logic device (CPLD). During leakage detection, the substrate management controller reads the target leakage alarm threshold from the CPLD and sends it to the negative input terminal of the voltage comparator via the digital-to-analog converter chip as a negative voltage value. The voltage comparator then compares the positive voltage value at the positive input terminal with the negative voltage value to determine whether a leakage alarm is issued. The positive voltage value is calculated by the leakage detection system based on the target liquid cooling configuration and leakage conditions.

[0037] Thirdly, this application discloses an electronic device, including:

[0038] Memory, used to store computer programs;

[0039] A processor is used to execute the computer program to implement the aforementioned disclosed method for setting a leakage alarm threshold.

[0040] Fourthly, this application discloses a computer-readable storage medium for storing a computer program; wherein, when the computer program is executed by a processor, it implements the aforementioned method for setting a leakage alarm threshold.

[0041] As can be seen, this application determines the leakage alarm threshold corresponding to each liquid cooling configuration; obtains the target liquid cooling configuration to be detected input by the user; determines the target leakage alarm threshold corresponding to the target liquid cooling configuration from the leakage alarm thresholds corresponding to each liquid cooling configuration; stores the target leakage alarm threshold in the complex programmable logic device (CPLD), so that when performing leakage detection, the substrate management controller reads the target leakage alarm threshold from the CPLD and sends the target leakage alarm threshold to the negative input terminal of the voltage comparator through the digital-to-analog converter chip as the negative voltage value, so that the voltage comparator compares the positive voltage value at the positive input terminal with the negative voltage value to determine whether to issue a leakage alarm; the positive voltage value is the voltage value calculated by the leakage detection system based on the target liquid cooling configuration and leakage situation. Therefore, this application further determines the target leakage alarm threshold based on the target liquid cooling configuration that needs to be detected, which is input by the user. The user can change the corresponding threshold by changing the input target liquid cooling configuration, so as to achieve flexible and convenient threshold change, without the need to fix the threshold and adjust the leakage detection sensitivity under different leakage configurations by changing the resistance value. This allows for more flexible leakage detection of different liquid cooling configurations. Attached Figure Description

[0049] 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.

[0050] Liquid-cooled servers typically employ a combination of liquid-cooled heatsinks, liquid-cooled pipes, and liquid-cooled pumps to dissipate heat from critical areas and high-power components such as the CPU, memory, and PCIe expansion cards. The liquid-cooled pipes contain different types of coolant, which is circulated and cooled by the liquid-cooled pump. While liquid cooling is highly efficient, a leak can cause short circuits in components on the PCB, resulting in irreversible damage to the server. Therefore, leak detection is crucial in liquid-cooled servers.

[0051] See Figure 1 The diagram shows a leakage detection design. The leakage detection line has 4-pin connectors at both ends. Pin 1 of these connectors is the leakage fault detection indicator pin, connected to the V+ input (positive input) of a voltage comparator. An alarm threshold is set by using voltage divider resistors (R4 and R5) at the V- input (negative input) of the voltage comparator. The voltage comparator operates as follows: when the voltage at the positive input (V+) is greater than the voltage at the negative input (V-), the comparator output is high (Vout = 3.3V in the diagram); when the voltage at the positive input is less than the voltage at the negative input, the comparator output is low (Vout = 0V in the diagram).

[0052] The alarm threshold V- = 3.3 × R5 × (R4 + R5), typically R4 = 4.7 kΩ, R5 = 10 kΩ, i.e., V- = 2.24 V; the leak detection voltage V+ = 3.3 * (R3 / / R7) × ((R3 / / R7) + R2); where R3 / / R7 = R3 × R7 / (R3 + R7).

[0053] When pins 2 and 3 of the leak detection line are shorted internally, and no leak occurs, the equivalent impedance R7 between terminals A and B is large. At this time, V+ ≈ 3.3V, which is greater than V-, and a leak alarm will not be triggered. When a leak occurs, terminals A and B are short-circuited, and the equivalent impedance R7 changes and decreases. When the leak is small, the equivalent impedance R7 is relatively large. Although V+ is divided, it is still greater than V-, and a leak alarm will not be triggered. When the leak is large, R7 decreases sharply, causing V+ to be less than V-, thus triggering a leak alarm. The equivalent impedance R7 of the leak detection line is affected by factors such as the type of leak detection line, the type of coolant, and the amount of leak. The leak detection sensitivity varies under different coolants and different heat dissipation configurations. Therefore, the leak detection sensitivity is usually modified by changing the resistance value of the external pull-up resistor R2 to adapt to the leak detection requirements of different liquid cooling configurations.

[0054] However, the current method for modifying the sensitivity of leakage detection requires modifying the electronic component, namely the resistance value of resistor R2, which is not flexible enough.

[0055] Therefore, this application proposes a leakage alarm threshold setting scheme, which can more flexibly detect leakage for different liquid cooling configurations.

[0056] This application discloses a method for setting a liquid leakage alarm threshold, applied to a substrate management controller in a liquid leakage detection system. The liquid leakage detection system further includes a voltage comparator, a digital-to-analog converter chip connected between the substrate management controller and the negative input terminal of the voltage comparator, and a complex programmable logic device connected to the substrate management controller. See also... Figure 2 As shown, the method includes:

[0057] Step S11: Determine the leakage alarm threshold corresponding to each liquid cooling configuration.

[0058] In this embodiment, the entire process of setting the target leakage alarm threshold is carried out after the production line assembly is completed and the diag program is started.

[0059] See Figure 3As shown, this is a leakage detection system provided in this application; R4 and R5 are not present in the figure. The Baseboard Management Controller (BMC), Digital to Analog Converter (DAC), and Complex Programmable Logic Device (CPLD) jointly control the negative voltage value at the negative input terminal of the voltage comparator. Figure 3 In the circuit, the chip switch (OE) and switch (SW) are used to simulate leakage. P3V3_STBY represents the DC voltage at the positive terminal of the power supply; the leakage detection voltage V+ = 3.3*(R3 / / R7)×((R3 / / R7)+R2); where R3 / / R7 = R3×R7 / (R3+R7); PRSNT_N is used to detect whether the leakage detection is working; Leakage_detect_N is used to transmit the leakage alarm signal.

[0060] In this embodiment, the leakage detection system further includes a board; correspondingly, determining the leakage alarm threshold corresponding to each liquid cooling configuration includes: reading the board to determine the leakage alarm threshold corresponding to each liquid cooling configuration.

[0061] In this embodiment, reading the board device to determine the leakage alarm threshold corresponding to each liquid cooling configuration includes: reading the board device to obtain the board device identifier (board ID) (ID is also known as IdentityDocument); determining the target item corresponding to the board device identifier, and obtaining the leakage alarm threshold corresponding to each liquid cooling configuration under the target item from the firmware of the baseboard management controller.

[0062] It should be noted that before reading the board device to determine the leakage alarm threshold corresponding to each liquid cooling configuration, the firmware of the baseboard management controller already stores the leakage alarm thresholds corresponding to different liquid cooling configurations determined after multiple tests. Furthermore, the different liquid cooling configurations are distinguished according to different items. The target item can be further determined through the board device identifier, and the liquid cooling configurations under the target item and their corresponding leakage alarm thresholds can be determined.

[0063] In one specific embodiment, the board device identifier can be represented by three binary digits, where 100 represents item 1, 101 represents item 2, etc.

[0064] Step S12: Obtain the target liquid cooling configuration that needs to be detected, as input by the user.

[0065] In this embodiment, the user can input the target liquid cooling configuration to be tested according to the actual situation. It should be noted that since the user inputs the information directly, no changes need to be made to the internal electronic components of the system, thus improving flexibility.

[0066] In this embodiment of the application, the diag program, which is started after the production line assembly is completed, is called to obtain the target liquid cooling configuration that needs to be tested, as input by the user.

[0067] Step S13: Determine the target leakage alarm threshold corresponding to the target liquid cooling configuration from the leakage alarm thresholds corresponding to each of the liquid cooling configurations.

[0068] In this embodiment, the target liquid cooling configuration is determined by comparing each liquid cooling configuration with the target liquid cooling configuration.

[0069] It should be noted that the target leakage alarm threshold is determined by the target liquid cooling configuration. This threshold is converted into a negative electrode voltage value, which has no precision limit and can be refined to multiple decimal places. The negative electrode voltage values ​​between different liquid cooling configurations can have very small differences. Therefore, the method can refine the granularity of the leakage detection sensitivity setting between different liquid cooling configurations.

[0070] Step S14: The target leakage alarm threshold is stored in the complex programmable logic device (CPLD). When performing leakage detection, the substrate management controller reads the target leakage alarm threshold from the CPLD and sends it to the negative input terminal of the voltage comparator via the digital-to-analog converter chip as a negative voltage value. The voltage comparator compares the positive voltage value at the positive input terminal with the negative voltage value to determine whether to issue a leakage alarm. The positive voltage value is the voltage value calculated by the leakage detection system based on the target liquid cooling configuration and leakage situation.

[0071] In this embodiment, storing the target leakage alarm threshold in the complex programmable logic device (CPLD) includes: storing the target leakage alarm threshold in the flash memory area (UFM) of the CPLD, wherein the memory area is as follows: Figure 3 As shown.

[0072] In this embodiment, the substrate management controller and the digital-to-analog converter chip, as well as the complex programmable logic device and the substrate management controller, are connected via a bidirectional two-wire synchronous serial bus (I2C, Inter-Integrated Circuit). Correspondingly, the target leakage alarm threshold is transmitted between the substrate management controller and the digital-to-analog converter chip, and between the complex programmable logic device and the substrate management controller, via the bidirectional two-wire synchronous serial bus.

[0073] In this embodiment, when the positive voltage value is less than the negative voltage value, the voltage comparator sends a leakage alarm to the substrate management controller through its output terminal (Vout).

[0074] It should be noted that this application does not change the positive voltage value by changing the resistance, but changes the negative voltage value by inputting different target liquid cooling configurations, so as to achieve the effect of flexibly detecting leakage of different liquid cooling configurations.

[0075] In this embodiment, the positive voltage value is the voltage value calculated by the leakage detection system based on the target liquid cooling configuration and the leakage situation. It should be noted that, under the condition that R3, R7 and R2 remain unchanged in this application, the positive voltage values ​​corresponding to different target liquid cooling configurations under the same leakage situation are different, and the positive voltage values ​​corresponding to the same target liquid cooling configuration under different leakage situations are different.

[0076] As can be seen, this application determines the leakage alarm threshold corresponding to each liquid cooling configuration; obtains the target liquid cooling configuration to be detected input by the user; determines the target leakage alarm threshold corresponding to the target liquid cooling configuration from the leakage alarm thresholds corresponding to each liquid cooling configuration; stores the target leakage alarm threshold in the complex programmable logic device (CPLD), so that when performing leakage detection, the substrate management controller reads the target leakage alarm threshold from the CPLD and sends the target leakage alarm threshold to the negative input terminal of the voltage comparator through the digital-to-analog converter chip as the negative voltage value, so that the voltage comparator compares the positive voltage value at the positive input terminal with the negative voltage value to determine whether to issue a leakage alarm; the positive voltage value is the voltage value calculated by the leakage detection system based on the target liquid cooling configuration and leakage situation. Therefore, this application further determines the target leakage alarm threshold based on the target liquid cooling configuration that needs to be detected, which is input by the user. The user can change the corresponding threshold by changing the input target liquid cooling configuration, so as to achieve flexible and convenient threshold change, without the need to fix the threshold and adjust the leakage detection sensitivity under different leakage configurations by changing the resistance value. This allows for more flexible leakage detection of different liquid cooling configurations.

[0077] This application discloses a specific method for setting a leakage alarm threshold. Compared to the previous embodiment, this embodiment further explains and optimizes the technical solution. See also... Figure 4 As shown, it specifically includes:

[0078] Step S21: Determine the leakage alarm threshold corresponding to each liquid cooling configuration.

[0079] For a more detailed description of the process of step S21, please refer to the relevant content disclosed in the foregoing embodiments, which will not be repeated here.

[0080] Step S22: Obtain the target liquid cooling configuration that needs to be detected, as input by the user.

[0081] For a more detailed description of the process of step S22, please refer to the relevant content disclosed in the foregoing embodiments, which will not be repeated here.

[0082] Step S23: Determine the target leakage alarm threshold corresponding to the target liquid cooling configuration from the leakage alarm thresholds corresponding to each of the liquid cooling configurations.

[0083] For a more detailed description of the process of step S23, please refer to the relevant content disclosed in the foregoing embodiments, which will not be repeated here.

[0084] Step S24: Store the target leakage alarm threshold in the complex programmable logic device.

[0085] For a more detailed description of the process of step S24, please refer to the relevant content disclosed in the foregoing embodiments, which will not be repeated here.

[0086] Step S25: Read the reference leakage alarm threshold in the complex programmable logic device and compare the reference leakage alarm threshold with the target leakage alarm threshold.

[0087] In this embodiment, to avoid errors in the target leakage alarm threshold during transmission to the complex programmable logic device (CPLD), resulting in the CPLD storing a different target leakage alarm threshold, a step is proposed: reading a reference leakage alarm threshold from the CPLD and comparing the reference leakage alarm threshold with the target leakage alarm threshold. If the comparison matches, the CPLD stores the target leakage alarm threshold; if the comparison does not match, the CPLD does not store the target leakage alarm threshold.

[0088] Step S26: If the comparison is consistent, the setting of the leakage alarm threshold is completed.

[0089] In this embodiment, if the comparison is consistent, the complex programmable logic device stores the target leakage alarm threshold, so the setting of the leakage alarm threshold can be terminated.

[0090] Step S27: If the comparison is inconsistent, proceed to the step of obtaining the target liquid cooling configuration to be detected by the user input, so as to re-store the target leakage alarm threshold to the complex programmable logic device, until the comparison is consistent and the setting of the leakage alarm threshold ends.

[0091] In this embodiment, if the comparison is inconsistent, the complex programmable logic device (CPLD) stores the target leakage alarm threshold, so it is necessary to retransmit the target leakage alarm threshold to the CPLD. Specifically, this application jumps to the step of obtaining the user input of the current target liquid cooling configuration to be detected and retransmits the threshold. This method allows the user to be aware of the transmission error.

[0092] It should be noted that you can also directly jump to the step of storing the target leakage alarm threshold to the complex programmable logic device, but at this time the user will not know that a transmission error has occurred.

[0093] As can be seen, this application obtains the target liquid cooling configuration to be detected input by the user; determines the target leakage alarm threshold corresponding to the target liquid cooling configuration from the leakage alarm thresholds corresponding to each liquid cooling configuration; stores the target leakage alarm threshold in the complex programmable logic device (CPLD); reads the reference leakage alarm threshold in the CPLD and compares the reference leakage alarm threshold with the target leakage alarm threshold; if the comparison is consistent, the setting of the leakage alarm threshold ends; if the comparison is inconsistent, the process jumps to the step of obtaining the target liquid cooling configuration to be detected input by the user to re-store the target leakage alarm threshold in the CPLD, until the comparison is consistent. Therefore, this application ensures that the target leakage alarm threshold is stored in the CPLD through comparison and jump steps, facilitating accurate leakage detection subsequently.

[0094] Accordingly, this application also discloses a leakage alarm threshold setting device applied to a substrate management controller of a leakage detection system. The leakage detection system further includes a voltage comparator, a digital-to-analog converter chip connected between the substrate management controller and the negative input terminal of the voltage comparator, and a complex programmable logic device connected to the substrate management controller. See [link to relevant documentation]. Figure 5 As shown, the device includes:

[0095] The first threshold determination module 11 is used to determine the leakage alarm threshold corresponding to each liquid cooling configuration;

[0096] Configuration acquisition module 12 is used to acquire the target liquid cooling configuration that needs to be detected, as input by the user.

[0097] The second threshold determination module 13 determines the target leakage alarm threshold corresponding to the target liquid cooling configuration from the leakage alarm thresholds corresponding to each liquid cooling configuration.

[0098] The threshold storage module 14 is used to store the target leakage alarm threshold in the complex programmable logic device (CLPD). When performing leakage detection, the substrate management controller reads the target leakage alarm threshold from the CLPD and sends it to the negative input terminal of the voltage comparator via the digital-to-analog converter chip as a negative voltage value. The voltage comparator then compares the positive voltage value at the positive input terminal with the negative voltage value to determine whether a leakage alarm is issued. The positive voltage value is calculated by the leakage detection system based on the target liquid cooling configuration and leakage situation.

[0099] As can be seen, this application determines the leakage alarm threshold corresponding to each liquid cooling configuration; obtains the target liquid cooling configuration to be detected input by the user; determines the target leakage alarm threshold corresponding to the target liquid cooling configuration from the leakage alarm thresholds corresponding to each liquid cooling configuration; stores the target leakage alarm threshold in the complex programmable logic device (CPLD), so that when performing leakage detection, the substrate management controller reads the target leakage alarm threshold from the CPLD and sends the target leakage alarm threshold to the negative input terminal of the voltage comparator through the digital-to-analog converter chip as the negative voltage value, so that the voltage comparator compares the positive voltage value at the positive input terminal with the negative voltage value to determine whether to issue a leakage alarm; the positive voltage value is the voltage value calculated by the leakage detection system based on the target liquid cooling configuration and leakage situation. Therefore, this application further determines the target leakage alarm threshold based on the target liquid cooling configuration that needs to be detected, which is input by the user. The user can change the corresponding threshold by changing the input target liquid cooling configuration, so as to achieve flexible and convenient threshold change, without the need to fix the threshold and adjust the leakage detection sensitivity under different leakage configurations by changing the resistance value. This allows for more flexible leakage detection of different liquid cooling configurations.

[0100] In one specific embodiment, the configuration acquisition module 12, the second threshold determination module 13, and the threshold storage module 14 are jointly used to acquire the target liquid cooling configuration that needs to be detected, as input by the user.

[0106] In one specific embodiment, the threshold storage module 14 includes:

[0108] In one specific embodiment, the leakage detection system further includes a circuit board device;

[0109] Accordingly, the first threshold determination module 11 includes:

[0110] The first threshold determination unit is used to read the board device to determine the leakage alarm threshold corresponding to each liquid cooling configuration.

[0111] In one specific embodiment, the first threshold determination unit is specifically used to read the board device to obtain the board device identifier;

[0112] The target item corresponding to the board device identifier is determined, and the leakage alarm threshold corresponding to each liquid cooling configuration under the target item is obtained from the firmware of the baseboard management controller.

[0113] In one specific embodiment, the substrate management controller and the digital-to-analog converter chip, as well as the complex programmable logic device and the substrate management controller, are connected via a bidirectional two-wire synchronous serial bus.

[0114] In one specific embodiment, when the positive voltage value is less than the negative voltage value, the voltage comparator sends a leakage alarm to the substrate management controller through its output terminal.
