Figure 2 The process of the detection method according to the embodiment of the present application is Figure 1 ,like Figure 2 As shown, the process includes the following steps:

[0028] Step S202, controlling the signal transmitting end to continuously transmit a differential signal pair of a target frequency through at least two of the transmission lines;

[0029] Step S204, when the signal receiving end does not receive the differential signal pair, controlling the signal transmitting end to adjust the frequency of the transmitted differential signal pair;

[0030] Step S206: When the signal receiving end does not receive the differential signal pair after frequency adjustment, it is determined that the server liquid cooling pipe is leaking.

[0031] In the above steps, exemplarily, the predetermined threshold includes but is not limited to: 2 mm, 3 mm, 5 mm, etc., the server leakage detection equipment also includes a baseboard control manager, and the input end and the output end of the transmission line are respectively connected to different pins of the baseboard control manager. In the above steps, the method also includes: when the signal receiving end does not receive the differential signal pair, determining that the server liquid cooling tube is leaking.

[0032] In the above steps, by adjusting the frequency of the differential signal pair when the differential signal pair of the target frequency is not received, and determining the leakage of the server liquid cooling tube according to the reception status of the differential signal pair after the frequency adjustment, the problem of false leakage alarm caused by the inability to avoid the electromagnetic environment in the server interfering with the voltage on the leakage detection line in the leakage detection method in the related art is solved, thereby improving the accuracy of leakage detection.

[0033] The execution subject of the above steps may be a server leakage detection device, etc., but is not limited thereto.

[0034] In an optional embodiment, when the differential signal pair is not received at the signal receiving end, the signal sending end is controlled to adjust the frequency of the transmitted differential signal pair, including: obtaining target information of the server where the server leakage detection device is located, and determining the type of the server and a predetermined rule for adjusting the frequency of the differential signal pair according to the target information; determining, according to the type of the server, a first frequency to be adjusted to the differential signal based on the predetermined rule, wherein the first frequency does not include the target frequency, the number of the first frequencies is one or more, and when the number of the first frequencies is multiple, the multiple first frequencies are the frequencies to which the frequency of the differential signal pair is to be adjusted in sequence, and the multiple first frequencies are different from each other; In the case where there are multiple first frequencies, the signal sending end is controlled to transmit the differential signal pair of each first frequency in sequence through at least two of the transmission lines, and when the signal receiving end receives the differential signal pair, it is determined that the server liquid cooling tube is not leaking, the frequency of the differential signal pair is stopped to be adjusted, and the first frequency of the differential signal pair received by the signal receiving end is determined as the target frequency; in the case where the first frequency is unique, the signal sending end is controlled to transmit the differential signal pair of the first frequency through at least two of the transmission lines, and when the signal receiving end receives the differential signal pair, it is determined that the server liquid cooling tube is not leaking, and the target frequency is updated to the first frequency of the differential signal pair received by the signal receiving end.

[0035] In the above steps, the target information includes but is not limited to: the model of the server, the electromagnetic noise information of the server during historical operation, and the predetermined rules include but are not limited to: the difference between the first frequency and the maximum value in the electromagnetic noise range included in the electromagnetic noise information is greater than a first predetermined threshold, the ratio between the first frequency and the maximum value in the electromagnetic noise range included in the electromagnetic noise information is greater than a second predetermined threshold, and so on. Exemplarily, when the electromagnetic noise generated during the historical operation of the server is strong, multiple first frequencies are determined according to the predetermined rules, wherein the difference between the multiple first frequencies and the target frequency is large. When the electromagnetic noise generated during the historical operation of the server is weak, a first frequency is determined, wherein the difference between the first frequency and the target frequency is small. Exemplarily, when there are multiple first frequencies, the frequency value of each first frequency is a predetermined multiple of the target frequency (for example, 5 times, 10 times, 100 times, etc.). For example, the target frequency is 100 Hz. When the electromagnetic noise is strong, multiple first frequencies are determined, for example, 1 KHz, 100 KHz. When the electromagnetic noise is weak, a first frequency is determined to be 300 Hz. The number of the first frequencies and the difference between the first frequency and the target frequency can be adjusted according to different application scenarios.

[0036] In the above steps, the first frequency to which the differential signal is to be adjusted is determined according to the target information, and the leakage of the liquid cooling tube of the server is determined according to the reception status of the first frequency, thereby avoiding the problem of false alarm of leakage caused by the influence of electromagnetic noise in the server on the transmission of the differential signal, and improving the accuracy of leakage detection.

[0037] In an optional embodiment, when the differential signal pair after frequency adjustment is not received at the signal receiving end, it is determined that the server liquid cooling pipe is leaking, including: when the number of the first frequencies is multiple and the signal receiving end does not receive any of the differential signal pairs of the first frequencies, it is determined that the server liquid cooling pipe is leaking; when the number of the first frequencies is one and the signal receiving end does not receive the differential signal pair of the first frequency, it is determined that the server liquid cooling pipe is leaking.

[0038] In an optional embodiment, according to the type of the server, determining the first frequency to which the differential signal is to be adjusted based on the predetermined rule includes: determining a target electromagnetic noise range in the server according to the type of the server; and determining the first frequency based on the predetermined rule according to the target electromagnetic noise range.

[0039] In the above steps, exemplarily, when the target electromagnetic noise range is between 100 MHz and 300 MHz and the target frequency is 100 MHz, the first frequency is determined to be 500 MHz, 1000 MHz and 1500 MHz.

[0040] In an optional embodiment, the first frequency is determined based on the predetermined rule according to the target electromagnetic noise range, including: when there are multiple first frequencies, determining the target difference between each of the first frequencies and the target frequency according to the target electromagnetic noise range, and determining the first frequency based on the target difference; when there is one first frequency, determining the target difference between the first frequency and the target frequency according to the target electromagnetic noise range, and determining the first frequency based on the target difference.

[0041] In the above steps, exemplarily, when the target electromagnetic noise range is between 100 MHz and 300 MHz and the target frequency is 100 MHz, the target difference is determined to be 200 MHz.

[0042] In an optional embodiment, the method also includes: in the case where there are multiple first frequencies, determining a target multiple of each first frequency and the target frequency according to the target electromagnetic noise range, and determining the first frequency based on the target multiple; in the case where there are multiple first frequencies, determining a target multiple of each first frequency and the target frequency according to the target electromagnetic noise range, and determining the first frequency based on the target difference.

[0043] In the above steps, exemplarily, when the target electromagnetic noise range is between 100 MHz and 300 MHz and the target frequency is 100 MHz, the target multiple is determined to be 1.5 times.

[0044] In an optional embodiment, the method further includes: determining a first ratio of a first difference between a maximum value and a minimum value in the target electromagnetic noise range to the minimum value, and when the first ratio is less than a first threshold, determining the sum of the maximum value and the first value as the first frequency, wherein the first value is determined according to the first ratio and the first difference;

[0045] When the first ratio is greater than the first threshold, a first number of the first frequencies is determined according to a rounded value of the ratio of the first ratio to the second value, and a plurality of first frequencies are determined according to the maximum value, the minimum value, the second value and the first number.

[0046] In the above steps, the first difference and the first threshold value can be preset and adjusted according to the application scenario. Determining the first number of the first frequency according to the rounded value of the ratio of the first ratio to the second value includes but is not limited to: determining the rounded value of the ratio of the first ratio to the second value as the first number of the first frequency, or determining the sum of the rounded value of the ratio of the first ratio to the second value and a third value as the first number of the first frequency. Determining multiple first frequencies according to the maximum value, the minimum value, the second value and the first number includes but is not limited to: determining the minimum value of the first frequency by determining the average value of the maximum value and the minimum value, and determining the remaining first frequencies according to the second value and the first number.

[0047] Exemplarily, when the target electromagnetic noise range is 100 Hz-600 Hz, the first threshold is 10, and the first value is 200 Hz, the first frequency is determined to be the first threshold. When the target electromagnetic noise range is 100 Hz-3000 Hz, the first threshold is 10, and the second value is 10, the first number is determined to be 3, and the first frequencies are determined to be 1550 Hz, 15500 Hz, and 155 KHz, respectively.

[0048] In the above steps, by accurately determining the first frequency according to the target electromagnetic noise range, electromagnetic noise interference in the service is effectively avoided, thereby improving the stability and accuracy of signal transmission.

[0051] In the above steps, by integrating the signal sending end and the signal receiving end in the BMC, centralized monitoring and management of the internal status of the server can be achieved, the hardware layout is simplified, and the system integration is improved. In addition, by using insulating tape to wrap the server liquid cooling pipe and the transmission line together, the impact of electromagnetic interference on the transmission line can be reduced, the integrity of the signal can be improved, and the false alarm rate can be reduced.
