All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 and fig. 2, fig. 1 is a first structural schematic diagram of a server leakage processing system according to an embodiment of the present invention, and fig. 2 is a schematic diagram of a liquid cooling server.
The server leakage processing system provided by the embodiment of the invention can comprise:
A liquid-cooled server cabinet provided with a server;
the first power switch is arranged on the liquid cooling server cabinet and connected between the server and the power supply (Power Supply Unit, PSU) module, the first power switch corresponds to the server one by one, and the first power switch is arranged at the inlet of the main board of the server;
the liquid leakage prediction module is arranged on the liquid cooling server cabinet and is used for predicting whether the server leaks or not based on the data information of the server and generating a corresponding liquid leakage prediction signal;
the liquid leakage detection module is arranged on the liquid cooling server cabinet and is used for detecting whether the server leaks liquid or not and generating a corresponding liquid leakage warning signal;
and the controller is arranged on the liquid cooling server cabinet and is respectively connected with the leakage prediction module and the leakage detection module, and is used for responding to any one of the leakage prediction signal and the leakage warning signal to represent server leakage, determining a first power switch corresponding to the server with the leakage, and closing the first power switch corresponding to the server with the leakage so as to disconnect the power supply of the power supply module to the server with the leakage.
In practical application, the leakage prediction module is used for predicting whether the server leaks, the corresponding leakage prediction signal is used for representing a prediction result, namely, a predicted result of whether the server leaks, and a mode of predicting whether the server leaks can be determined according to practical needs. The liquid leakage detection module is used for detecting whether the server truly leaks, and the corresponding liquid leakage warning signal is used for representing a detection result, namely, a detected result of whether the server leaks. Therefore, as long as one leakage prediction signal and leakage warning signal represent the leakage of the server, the first power switch needs to be turned off so as to cut off the power of the server main board, the circuit devices are protected from being damaged, the double protection function ensures the reliability of the system, but when a certain detection mechanism cannot respond in time due to certain devices, the other detection mechanism can work normally, and the risk of the leakage short circuit is reduced.
In a specific application scenario, the types of the leakage prediction signal and the leakage warning signal may be determined according to the application scenario, for example, the leakage prediction signal and the leakage warning signal may be both text signals or both digital signals, etc., and the present invention is not limited herein.

In addition, other structures on the liquid cooling server cabinet provided by the invention can refer to corresponding technologies, for example, the liquid cooling server cabinet can also comprise a power supply module, an indicator light and the like, and the invention is not limited in detail herein. It should be noted that parameters such as a type of the power supply module, a power supply voltage, etc. and a type, a number of servers, etc. may be determined according to a specific application scenario, that is, the 12V voltage shown in fig. 1 is an exemplary voltage; the controller may be a baseboard management controller (Board Management Controller, BMC) or the like, and the controller may be provided inside the server or outside the server or the like, and the present invention is not limited thereto.
It should be further noted that, under the condition that a plurality of servers are installed on the liquid cooling server cabinet, the liquid leakage detection modules can be in one-to-one correspondence with the servers, and the single liquid leakage detection module is only responsible for detecting whether liquid leakage occurs in the single server, or the single liquid leakage detection module corresponds to the plurality of servers, and the single liquid leakage detection module is responsible for detecting whether liquid leakage occurs in the plurality of servers. Similarly, the leakage prediction modules may be in one-to-one correspondence with the servers, or may be a single leakage prediction module corresponding to a plurality of servers, or the like, and the present invention is not limited herein. In addition, the leakage detection module can be connected with the server main board through a connector and the like.
The invention provides a server leakage processing system, which is provided with a liquid cooling server cabinet of a server; the first power switch is arranged on the liquid cooling server cabinet and connected between the server and the power supply module, the first power switch corresponds to the server one by one, and the first power switch is arranged at the entrance of the main board of the server; the liquid leakage prediction module is arranged on the liquid cooling server cabinet and is used for predicting whether the server leaks or not based on the data information of the server and generating a corresponding liquid leakage prediction signal; the liquid leakage detection module is arranged on the liquid cooling server cabinet and is used for detecting whether the server leaks liquid or not and generating a corresponding liquid leakage warning signal; and the controller is arranged on the liquid cooling server cabinet and is respectively connected with the leakage prediction module and the leakage detection module, and is used for responding to any one of the leakage prediction signal and the leakage warning signal to represent server leakage, determining a first power switch corresponding to the server with the leakage, and closing the first power switch corresponding to the server with the leakage so as to disconnect the power supply of the power supply module to the server with the leakage.
The beneficial effects of the invention are as follows: the server is predicted whether to leak by the leak prediction module and generates a corresponding leak prediction signal, the leak detection module is used for detecting whether the server leaks and generating a corresponding leak warning signal, and the controller is used for powering off the server by closing the first power switch after any one of the leak prediction signal and the leak warning signal characterizes the server leaks, so that whether the server is predicted to leak or the server is detected to leak already, the server can be controlled to be powered off, and the safety of the server is ensured; the first power switch corresponds to the servers one by one, so that each server is provided with the first power switch, and after the controller only turns off the first power switch of the server with the leakage, only the server with the leakage cannot obtain current and cannot work, and other servers without the leakage can work normally, so that the working stability of other servers is ensured; in addition, because the first power switch is arranged at the entrance of the main board of the server, no current exists in the server after the first power switch is turned off, the risk that the server main board is damaged due to short circuit caused by liquid leakage is further avoided, and the safety of the server when the liquid leakage occurs is improved.

The AND gate logic device is connected with the first power switch and the first complex programmable logic device and is used for performing AND operation on the first enabling signal and the second enabling signal to obtain a power enabling signal so as to perform enabling control on the first power switch based on the power enabling signal; in the process, when at least one of the first enabling signal and the second enabling signal is used for controlling the first power switch to be turned off, the obtained power enabling signal is used for controlling the first power switch to be turned off, and only when the first enabling signal and the second enabling signal are used for controlling the first power switch to be turned on, the obtained power enabling signal is used for controlling the first power switch to be turned on;
