Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As described in the background section, referring to fig. 1, the water-cooled process is similar to the air-cooled process, starting with an integrated heat sink connected to the CPU, i.e., a metal lid, which has a bottom plate coated with a thermal paste on its surface, which allows for more efficient heat transfer between the two surfaces. The metal surface of the base plate is part of a water cooling head in a liquid cooling system, which is designed to be filled with a cooling liquid. As the coolant flows through the water head, it absorbs heat from the base plate, and then it continues to move through the liquid cooling system and flows up through one of the two pipes to the radiator. The heat sink exposes the liquid to air to assist in heat dissipation, and a fan connected to the heat sink blows heat away from the heat sink. The coolant then re-enters the water head and the cycle begins again. When the assembly of the pipeline with the interfaces of the radiator and the water cooling head is not accurate enough, or the pipeline is aged after long-term use to generate catalysis, the leakage problem can be caused. When the amount of the leaked liquid is large, the cooling liquid is not only scattered outside the pipeline, but also can spread into the chassis system to cause larger loss.
In order to solve the problems, the invention creatively provides a method, a device and computer equipment for processing the liquid leakage of a server liquid cooling system, which judge whether the liquid cooling system leaks or not by using the current values of at least two liquid leakage detection lines wound on the outer surface of the server liquid cooling system in parallel, predict the liquid leakage amount by using a gray model, process the liquid leakage before the liquid leakage extends to a case system and effectively avoid the damage caused by the liquid leakage extending to the case system. The embodiments of the present application will be described in detail below with reference to the drawings and various embodiments.
The first embodiment is as follows: in this embodiment, a liquid leakage processing architecture of a liquid cooling system of a server in the present application is described.
Specifically, referring to fig. 2 and 3, the architecture includes: a leakage detection line, a BMC (Board Management Controller), and a gray model module.
The leakage detection lines are at least two and are wound on the surface of the server liquid cooling system in parallel, and the leakage detection lines are connected with a power supply for supplying power to the leakage detection lines. Preferably, the leakage detection line is wound on the surface of the pipeline in the server liquid cooling system in parallel. When no leakage of the cooling liquid occurs, the current of the leakage detection line is constant, when the leakage of the cooling liquid occurs, the cooling liquid seeps out of the pipeline, and the cooling liquid between the leakage detection lines forms a conductor, so that the current in the leakage detection line is increased.
The BMC periodically acquires the current value in the leakage detection lines to judge whether the cooling liquid exists between the leakage detection lines, thereby monitoring whether the cooling liquid leaks.
The grey model module acquires a current value in the leakage detection line from the BMC, predicts the leakage amount of the cooling liquid, executes a corresponding strategy, processes the cooling liquid before the cooling liquid spreads to the case system, and effectively prevents the cooling liquid from permeating into the case system.
Example two: based on the structure of liquid leakage processing of the liquid cooling system of the server introduced in the first embodiment, the present embodiment is introduced with reference to fig. 4, where a safety detection process of remote control of a vehicle in the present application is described.
Specifically, referring to fig. 4, based on the method for processing the liquid leakage of the server liquid cooling system disclosed in the present application, the process of processing the liquid leakage of the server liquid cooling system includes:
s410, obtaining the current value of the leakage detection line, wherein at least two leakage detection lines are wound on the outer surface of the server liquid cooling system in parallel, and the leakage detection line is connected with a power supply for supplying power to the leakage detection line.
Specifically, the server liquid cooling system comprises a liquid cooling head, a radiator and a liquid cooling circulation pipeline which is communicated with the liquid cooling head and the radiator to form a closed loop; the liquid cooling head is arranged on the surface of a metal cover of the server CPU, and the liquid leakage detection line is wound on the surface of the liquid cooling circulation pipeline in parallel.
Preferably, the BMC periodically obtains the current value of each leakage detection line to obtain a current value sample set, and the obtaining period is less than or equal to 30s.
Illustratively, the initial value of the current value sampling is 4, and every 30 seconds is set as the sampling interval.
And S420, obtaining a predicted leakage amount based on the preset gray model and the current value.
Specifically, the preset gray model is a GM (1,1) gray model, which is the most widely used prediction model. Compared with the traditional prediction model which needs a large amount of historical data to establish the prediction model, the GM (1,1) gray model can be quickly established without a large amount of data, and according to the definition of the model, the model can be established and predicted by only needing four strokes of data at least, which is the biggest characteristic of the model.
Specifically, the BMC obtains a current value, and inputs the current value into a preset grey model to obtain the predicted leakage amount.
Preferably, the present step comprises:
and S421, correcting the number of the samples in the current value sample set to obtain a corrected current sample set.
Specifically, the number of samples in the current value sample set is modified to achieve the optimized average error value.
And S422, obtaining a predicted leakage amount based on the corrected current sample set and a preset gray model.
Preferably, the present step comprises:
s4221, sorting all correction current values in the correction current sample set to obtain a first current value sequence.
Obtaining a first current value sequence by arranging all the corrected current values in the corrected current sample set in a sequence, as follows:
X (0) ＝{X (0) (1)，X (0) (2)，…，X (0) (i)，…，X (0) (n)} (1)
in the formula X (0) (i) For the sequence data at time order i, n is the last time order, and its value should be not less than 4.
And S4222, accumulating, generating and processing the first current value sequence to obtain a second current value sequence.
Using a sequence X of first current values (0) Performing accumulation generation operation to convert the current value into a second current value sequence X (1) So that original sequences with larger variation and irregular sequences present more mild and obvious rules after conversion. Comparing the AGO (accumulated Generation Operator) converted second current value sequence with the first current value sequence X (0) It is easier to model for approximation.
The second current value sequence is as follows:
X (1) ＝{X (1) (1)，X (1) 2，…，X (1) (k)，…，X (1) (n)} (2)
wherein X (1) And X (0) The conversion relationship is as follows:
s4223, generating a predicted leakage amount based on the preset gray model and the second current value sequence. Preferably, the preset gray model is a GM (1,1) model, and is expressed by a gray differential equation:
X (0) (k)+aZ (1) (k)＝b，k＝2，3，...，n； (4)
wherein: a and b are undetermined parameters;
specifically, the method comprises the following steps:
s42231 based on Z (1) (k)＝αX (1) (k)+(1-α)X (1) (k-1) (formula (5))
Calculating the ash differential equation to obtain an intermediate differential equation:
wherein: alpha is a setting parameter.
α is usually set to 0.5, and modification adjustment is started when the data structure is special.
S42232, solving the undetermined parameters a and b based on the ash differential equation.
Specifically, the parameters a and b of the GM (1,1) model are solved by the gray differential equation, equation (4), and are represented as a matrix:
order to
The matrix equation is then:
Y＝BA (8)
estimating the value of the matrix A by least squares method (order least-square method) to make the error matrix E = Y-BA
Q＝(Y-BA) T (Y-BA)；
To find the parameter a that minimizes Q, then:
s42233, and obtaining the predicted leakage amount based on the values of the undetermined parameters a and b obtained through solving and the intermediate differential equation.
In particular, will be solved
And with
Substituted into equation (6) to solve X (1) (k+1)。
Then X is put in (1) (k + 1) is subjected to inverse accumulation to generate and reduce the X (0) (k + 1), and the obtained value is the value for predicting the amount of leakage.
From equation (3):
the predicted value of the future time xi can be obtained by the following formula:
and S430, executing a corresponding leakage treatment method based on the predicted leakage amount and a preset leakage strategy.
Preferably, the method for performing corresponding leakage treatment based on the predicted leakage amount and the preset leakage strategy comprises:
s431, judging whether to open a liquid nitrogen release switch valve or not based on the predicted leakage amount and a preset leakage strategy, wherein the liquid nitrogen release switch valve is communicated with the server liquid cooling system to supply cooling liquid to the server liquid cooling system;
if yes, opening the liquid nitrogen release switch valve;
if not, closing the liquid nitrogen release switch valve.
Illustratively, the preset leakage strategy content is as follows: if the predicted leakage amount is larger than or equal to the preset leakage threshold value, opening a liquid nitrogen release switch valve; and if the predicted leakage amount is less than the preset leakage threshold value, closing the liquid nitrogen release switch valve.
When the predicted leakage amount is large, the circulating cooling liquid in the liquid cooling system of the server is supplemented, or the gas valve of the liquid nitrogen is controlled to be closed to stop supplementing the cooling liquid under the condition of no leakage.
In a preferred embodiment, after S410, the method further includes:
and SA1, judging whether the current value of the leakage detection line is greater than a preset current threshold value.
If yes, enter SA2.
Specifically, since the leakage detection lines are at least two and parallel, when the server liquid cooling system has a leakage situation, the leaked cooling liquid forms a conductor between the leakage detection lines, so that the current of the leakage detection lines is increased and is larger than the stable current value of the leakage detection lines which are not in the leakage environment, namely the preset current threshold value, and the leakage situation is determined.
And SA2, sending an alarm notice to the management client based on the network serial port.
After the liquid leakage condition is judged to have occurred, a warning notice is sent to the management client based on the network serial port, so that a manager can timely process and confirm the liquid leakage condition of the server liquid cooling system.
