and 4, step 4: controlling the anti-static brush to automatically return to the original position;
and 5: and starting standard cleaning and executing the step 3.
It should be noted that the step of detecting the cleanliness inside the server includes:
when the server is started, a laser transmitter positioned on one side of the case emits a light source to scan dust particles which are larger than or equal to a set value in the case, and a laser receiver positioned on the other side of the case receives the light source and calculates the number of the dust particles which are larger than or equal to the set value in the case;
the BMC calculates the cleanliness according to the number of the received dust particles and outputs the calculation result to the control panel.
In some embodiments, in step 2, when it is detected that the cleanliness of a certain block in the server is higher than the set value, the step of controlling the anti-static brush of the server upper cover to move to the block and starting the anti-static brush of the server upper cover to clean the corresponding block includes:
when the anti-static brush is in place, the anti-static brush and the upper cover of the server are in a parallel state, and the in-place indicator light is green representing that the anti-static brush is not in a working state;
when the cleanliness of a certain block is detected to exceed 7 levels, the control panel positioned on the upper cover of the server receives an electric signal, the in-place indicator lamp is controlled to be red representing the working state, the rotating motor is controlled to rotate to drive the anti-static brush to turn downwards, the anti-static brush and the upper cover of the server are positioned at the vertical position after turning downwards, the anti-static brush is controlled to start working, and dust of the corresponding block is cleaned;
when the cleanliness of three or more blocks exceeds 7 levels, the control panel receives an electric signal and controls the in-place indicator lamp to turn red, the rotating motor is controlled to rotate to drive the anti-static brush to turn downwards, the anti-static brush and the server upper cover are positioned at the vertical position after turning downwards, the anti-static brush is controlled to start working, and corresponding block dust is cleaned.
It should be noted that when the cleanliness of a block is detected to exceed 7 levels, the cleaning mode is a fast cleaning mode. After the cleaning process is started, the control panel positioned on the upper cover of the server receives the electric signal, so that the anti-static brush is started to work to clean the corresponding block. Detecting the cleanliness of the block again after cleaning is finished, and if the cleanliness is smaller than a set value, returning the anti-static brush to the original position; and if the cleanliness is still larger than the set value, starting standard cleaning. When the number of pairs of laser emitters and laser receivers is four, when the cleanliness of three or more blocks is detected to exceed 7 levels at the same time, the cleaning is performed rapidly. After the cleaning process is started, the control panel positioned on the upper cover of the server receives the electric signal, so that the anti-static brush is started to work to clean the inside of the whole case. Detecting the cleanliness of the block again after cleaning is finished, and if the cleanliness is smaller than a set value, returning the anti-static brush to the original position; and if the cleanliness is still larger than the set value, starting standard cleaning. When the cleanliness of all the blocks is less than 7 grades, the anti-static brush positioned on the upper cover of the server does not work.
When the cleanliness of the block exceeds 8 grades, i.e. the number of 0.5 μm dust particles γ =3500000pc/m ^3, the cleaning is performed with a strong force, and the cleaning process is the same as the cleaning process when the cleanliness exceeds 7 grades.
Here, the quick cleaning mode: cleaning a single block for three minutes;
and (3) standard cleaning mode: cleaning a single block for six minutes;
a powerful cleaning mode: cleaning a single block for four times;
the cleaning method adopts the components such as an anti-static brush, a control panel, an X-axis moving mechanism, a Y-axis moving mechanism and the like at the position of the upper cover of the server. When the anti-static brush is in place, the anti-static brush and the upper cover of the server are in a parallel state, the anti-static brush stands below the upper cover of the maintainable brush, and the in-place indicator lamp is green and represents that the anti-static brush is not in a working state. When the cleanliness of a certain block is detected to exceed 7 levels, the control panel positioned on the upper cover of the server receives an electric signal, and the on-site indicator lamp turns red to represent that the block is in a working state. Turning down and starting the anti-static brush, wherein the anti-static brush and the upper cover of the server are in a vertical position after being turned down, and the anti-static brush starts to work to clean corresponding block dust; when the cleanliness of three or more blocks exceeds 7 levels, the control panel positioned on the upper cover of the server receives an electric signal, the in-place indicator lamp turns red, the anti-static brush is in a working state, the anti-static brush turns downwards and is started, the anti-static brush and the upper cover of the server are in a vertical position after turning downwards, and the anti-static brush starts to work to clean dust in the whole server. The anti-static brush is positioned on the X-axis moving mechanism and can move left and right on the X-axis moving mechanism. The X-axis moving mechanism is connected with the Y-axis moving mechanism, and the X-axis moving mechanism can move up and down on the Y-axis moving mechanism. The cleaning rule of the whole server is front-back cleaning, namely the anti-static brush is positioned at the leftmost side of the X-axis moving mechanism, and then the X-axis moving mechanism moves up and down on the Y-axis moving mechanism to complete left-side cleaning; then the brush is moved to the right to the middle position of the X-axis moving mechanism, and then the X-axis moving mechanism moves up and down on the Y-axis moving mechanism to complete middle cleaning; and finally, the brush is shifted to the right side of the X-axis moving mechanism, and then the X-axis moving mechanism moves up and down on the Y-axis moving mechanism to complete right side cleaning, so that one round of cleaning work is completed. When the work is finished, the cleanliness detection is carried out again in the server, when the detection value is smaller than the set cleanliness value, the anti-static brush can automatically return and fold, and the on-site indicator lamp is changed from red to green; when the detected value is larger than the set cleanliness value, the anti-static brush can clean the block with the cleanliness larger than 7 levels again until the cleanliness is smaller than the set value.
In some embodiments, the invention also discloses a method for conveniently maintaining the brush. Whether the anti-static brush is in a working state or not can be judged through the in-place indicator lamp capable of maintaining the upper cover of the brush, and when the indicator lamp is in a green state, the anti-static brush is in a position and is not in a working state, so that the maintenance operation of the anti-static brush can be carried out; when the indicator light is red, the anti-static brush is not in place, and the maintenance operation of the anti-static brush cannot be carried out. The reset key is arranged on the maintainable brush upper cover, and when the maintainable person maintains the maintainable brush, the maintainable person encounters the brush and works, and the anti-static brush can stop working and reset by pressing the reset key. When the indicator light is green, a maintainer can open a lockset capable of maintaining the upper cover of the hairbrush to take out the upper cover of the maintainable hairbrush together with the control panel and the anti-static hairbrush, so as to carry out maintenance work of the anti-static hairbrush and the control panel, and the server detects that the upper cover of the maintainable hairbrush is not in place and is in a maintenance mode. After the anti-static brush and the control panel are maintained, the maintainable brush upper cover is restored by maintenance personnel, the upper cover lock is locked, the maintenance is completed, and the server detects that the maintainable brush upper cover is in place and is in an operation mode. The method can judge whether the anti-static brush is in a working state through the external indicator lamp. If the anti-static brush is not in a working state, the anti-static brush and the control panel can be maintained through the maintainable brush upper cover arranged after the server upper cover is opened, and the integral server upper cover of the case does not need to be detached.
Under the condition that the anti-static brush is not maintained timely, more dust can be stuck on the anti-static brush, so that the cleaning efficiency is lowered, and the final cleaning purpose cannot be achieved by the whole process. In some embodiments, a method of brush self-cleaning is also provided. An anti-static brush box is arranged on the outer wall of the server box body, and an unused anti-static brush and non-conductive electrolyte are arranged in the anti-static brush box. The number of the anti-static brushes is set to five based on the consideration of the size of the occupied space of the anti-static brush box and the use frequency. The brush self-cleaning method can realize the automatic replacement of the anti-static brush in the case and the anti-static brush in the anti-static brush box, and the used anti-static brush realizes the automatic cleaning. The replacement device of the whole brush is driven by the chain device, and when the used anti-static brush recovers the anti-static brush box, the electrolyte on the left side can soak the anti-static brush for cleaning. And then the chain device is driven, and the cleaned anti-static brush moves forwards to wait to be replaced in the case. The inside in-process of server is changed to waiting for, and the clear antistatic brush dries through natural air-drying's mode, and it is 2 hours to dry for a long time. The next used anti-static brush will be soaked in the electrolyte for cleaning. The replacement rule of the anti-static brush in the case is that the brush is replaced once after being cleaned for fifty times. When the anti-static brush in the case finishes the fifty-th cleaning and returns, the indicator light turns red and the server turns into the maintenance mode. At the moment, the chain device starts to work, the chain device drives the used anti-static brush to enter the anti-static brush box, and the cleaned/new anti-static brush is brought into the case of the server to complete replacement. After replacing five times, namely all the brushes in the anti-static brush box are replaced once, only the anti-static brushes in the server case are new brushes at the moment, when the only new anti-static brushes in the server case are cleaned for forty times, the warning information in the BMC can warn the user that all the anti-static brushes are replaced and the service life of the current brushes is about to reach the upper limit, and the user can select to continue to use or replace the anti-static brush box. And after the user or maintenance personnel replace the anti-static brush box, resetting the replacement count and restarting the counting. When the user selects to continue using, the anti-static brush can continue to execute the instruction according to the signal of the control board, once the service life of the anti-static brush is exhausted and the cleanliness detection value is higher than 9 levels, namely the number gamma of 0.5 mu m dust particles is =35000000pc/m ^3, the BMC can alarm and inform the user, and the server is stopped after three minutes. The server is automatically shut down after three minutes, requiring manual cleaning of the dust and replacement of the anti-static brush box. The anti-static brush in the case and the anti-static brush in the anti-static brush box can be automatically replaced, and the used anti-static brush can be automatically cleaned.
