The leakage simulation module is a leakage simulation chip or MOS tube combined logic circuit
The liquid leakage detection small plate is a detection board card used for detecting whether liquid leakage occurs in devices such as a liquid cooling pipe in the liquid cooling server; the small liquid leakage detection plate comprises a liquid leakage detection and alarm module used for detecting liquid leakage and sending out an alarm signal.
The liquid leakage detection cable is a cable which is arranged in the liquid cooling server and used for detecting liquid leakage, and avoids a server mainboard part; the liquid leakage detection cable is arranged along the diameter of the liquid cooling pipeline; the liquid cooling pipe path is a liquid cooling pipe arrangement route.

Based on the system for detecting the liquid leakage of the liquid cooling server by the BMC, the invention also provides a method for detecting the liquid leakage of the liquid cooling server by the BMC. Fig. 2 is a signal processing process diagram of a method for detecting liquid leakage of a liquid-cooling server by BMC according to embodiment 1 of the present invention.
Firstly, the BMC sends out a leakage simulation enabling signal to the CPLD for triggering the leakage simulation function. In embodiment 1 of the present invention, the low level of the leak simulation enable signal is active, and the state where no leak occurs during normal operation is the high level. When the liquid leakage simulation enabling signal is at low level, the liquid leakage simulation function is triggered.
And after receiving the low-level leakage simulation enabling signal sent by the BMC, the CPLD immediately sends out a leakage simulation control signal, the low level of the leakage simulation control signal is effective, and the normal state without leakage is a high level. When the leakage simulation enabling signal detected by the CPLD is high level, no processing is performed; when the CPLD detects that the leakage simulation enabling signal is at a low level, the leakage simulation control signal at the low level is output.
When the low level of the leakage simulation control signal is sent to the leakage simulation module, the leakage simulation module pulls the leakage simulation signal group from the high level to the low level. And the leakage simulation module is used for carrying out leakage simulation level conversion on the leakage simulation signal set. The leakage simulation signal set is a set of leakage simulation signals and is mainly signals set correspondingly by referring to detection points of leakage detection in the current server. If there are 4 detection points required to detect a leak, the signal set is also set to 4 corresponding leak simulation signals, both of which are 1: 1. The detection point is flexibly set according to the position to be detected actually.
The leakage detection cables are arranged inside the server along with the liquid cooling pipes, and the specific required quantity is set according to the detection point positions which need to be detected actually, for example, 4 detection points are arranged, and correspondingly, 4 leakage detection cables are also arranged. The weeping detects the cable can be that two single lines are around each other, and is insulating between two lines, and when only the weeping, two single lines just can be because of liquid cold water short circuit, and then trigger the weeping and detect. When the simulation weeping function, the weeping simulation signal group carries out the short circuit to the end of two single lines, perhaps draws low level to one of them main detection line, and simulation liquid cooling water drips on the cable.
And after the small liquid leakage detection plate detects a low-level liquid leakage simulation signal set, a first liquid leakage alarm signal set is sent to the CPLD through the liquid leakage alarm cable. The liquid leakage alarm cable is mainly a cable for sending liquid leakage alarm to the main board, and the cable comprises alarm signals of all detection points.
The number of the first leakage alarm signals in the first leakage alarm signal group is equal to the number of the detection points, and the first leakage alarm signals are respectively used for detecting leakage alarms of the detection points. The first liquid leakage alarm signal group is in a high level state when liquid leakage does not occur normally, and is changed into a low level state when liquid leakage is triggered. And the CPLD carries out treatments such as debouncing on the received first liquid leakage alarm signal group to obtain a second liquid leakage alarm signal group, wherein the second liquid leakage alarm signal group is in a high level state when liquid leakage does not normally occur, and is changed into a low level state when liquid leakage is triggered.
When the BMC receives a second leakage alarm signal sent by the CPLD, firstly, whether the alarm triggered by the leakage simulation function is sent is judged, and when the judgment is that the simulation function is verified, namely, a leakage simulation control signal is sent by the BMC, at the moment, the BMC displays that the simulation verification is successful through interfaces such as a web page or a serial port. When the judgment is not that the simulation function is verified, namely the leakage simulation control signal is not controlled, and the low level change of the second leakage alarm signal is received, the BMC sends out a leakage alarm prompt through interfaces such as a web page or a serial port and prompts a corresponding detection point. For example, show: if a liquid leakage occurs at the detection point 1, emergency treatment is required.
Fig. 3 is a flowchart of a method for BMC detecting liquid leakage of a liquid cooling server according to embodiment 1 of the present invention
In step S301, the process flow is started.
In step S302, the BMC sends a low-level leakage simulation enable signal to the CPLD to trigger the leakage simulation.
In step S303, after receiving the low-level leakage simulation enable signal sent by the BMC, the CPLD sends a low-level leakage simulation control signal to control the leakage simulation module. And the leakage simulation module converts the invalid leakage simulation signal set into an effective leakage simulation signal set.
In step S304, after the small leak detection panel detects the low-level leak analog signal group, the first leak alarm signal group is transmitted to the CPLD through the leak alarm cable.
In step S305, the CPLD performs debouncing processing on the first leakage alarm signal group to obtain a second leakage alarm signal group, and then sends the second leakage alarm signal group to the BMC.
In step S306, it is determined whether the alarm is an alarm triggered by the leak simulation function or an alarm triggered by the leak of the detection point. If the alarm triggered by the leakage simulation function is detected, executing step S307; if the alarm triggered by the leakage analog signal group is not present, step S308 is executed.
In step S307, the simulation test success is displayed through the display interface.
In step S308, the BMC displays a prompt for the alarm at the monitoring point through the display interface.
In step S309, the entire flow ends.
