Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0050] First, Figure 1 A flow chart of a computer room air conditioning method provided by an embodiment of the present disclosure, such as Figure 1 As shown, the computer room air conditioning method of the embodiment of the present disclosure includes:

[0051] S1: Collect temperature information of each area in the computer room, and upload the collected temperature information of the computer room to the central control module.

[0052] Specifically, an infrared detection module is used to collect temperature information of each area in the computer room, and the collected temperature information of the computer room is uploaded to the central control module. The air conditioner is set in the central area of ​​the computer room, and multiple areas can be set around the central area. Each area is correspondingly set with an infrared detection module, which is used to collect temperature information of the corresponding area.

[0053] S2: The central control module receives the temperature information of the computer room, simulates the cooling effect and cooling time of the air conditioner, and determines the working mode of the air conditioner.

[0054] Specifically, the central control module receives the temperature information of the computer room and distributes the temperature information of the computer room to the temperature distribution unit in the central control module. The temperature distribution unit processes the temperature information of the computer room, simulates the cooling effect and cooling time of the air conditioner, and determines the working mode of the air conditioner.

[0055] S3: Detect the real-time temperature information of each area of ​​the computer room after the air conditioner is working, and send the detection results to the central control module.

[0056] Specifically, after the air conditioner has been working for a period of time, the infrared detection module detects the real-time temperature information of each area of ​​the computer room, and sends the detected real-time temperature information of each area of ​​the computer room to the central control module. Accordingly, each area of ​​the computer room is correspondingly provided with a color tracking unit, which is used to check the real-time temperature information of the corresponding area.

[0057] S4: The central control module receives and analyzes the real-time temperature information of each area of ​​the computer room, adjusts the working mode of the air conditioner according to the analysis results, and controls the switch of the electric control valve connected to the air outlet duct.

[0058] Specifically, the central control module also includes a color tracking unit. The central control module receives the real-time temperature information of each area of ​​the computer room, and distributes the real-time temperature information of each area of ​​the computer room to the color tracking unit. The color tracking unit analyzes the real-time temperature information, adjusts the working mode of the air conditioner according to the analysis result, and controls the switch of the electric control valve of the connecting air outlet. Among them, the air conditioner is set in the central area of ​​the computer room, so the connecting air outlet in the central area of ​​the computer room is always kept in an open state and is not closed. The connecting air outlets in the surrounding areas open or close the electric control valves according to the temperature conditions.

[0059] In some examples, the central control module receives the temperature information of the computer room, simulates the cooling effect and cooling time of the air conditioner, and determines the working mode of the air conditioner, specifically including:

[0060] S21: Receive temperature information of the equipment room, and distribute the temperature information to a temperature distribution unit.

[0061] Specifically, the central control module receives the temperature information of the computer room sent by the infrared detection module, and distributes the temperature information to the temperature distribution unit in the central control module.

[0062] S22: The temperature distribution unit calculates the temperature distribution and cooling requirements of the computer room based on the fluid dynamics model and the heat transfer model, and feeds the calculation results back to the central control module.

[0063] Specifically, the temperature distribution unit includes a fluid dynamics model and a heat transfer model. The temperature distribution unit calculates the temperature distribution and cooling requirements of the computer room through the fluid dynamics model and the heat transfer model, and feeds back the calculation results to the central control module. The cooling requirements include the cooling time and the optimal temperature of the cooling in the computer room.

[0064] S23: The central control module selects a preset air-conditioning operation mode according to the feedback result, and controls the operation of the air-conditioning.

[0065] Specifically, the central control module selects a preset air-conditioning working mode according to the calculation result fed back by the temperature distribution unit, and controls the working state and start / stop state of the air-conditioning.

[0069] S42: The color tracking unit analyzes the real-time temperature information of each area of ​​the computer room through color space conversion, threshold setting, and color tracking, and feeds the analysis results back to the central control module.

[0070] Specifically, the color tracking unit analyzes the real-time temperature information of each area of ​​the computer room through color space conversion, threshold setting, color tracking, etc., and feeds the analysis results back to the central control module.

[0071] S43: The central control module adjusts the working mode of the air conditioner according to the analysis result, and controls the switch of the electric control valve connected to the air outlet duct.

[0072] Specifically, the central control module adjusts the working mode of the air conditioner according to the analysis results, and controls the opening and closing of the electric control valve connected to the air outlet. For example, according to the analysis results, the air outlet temperature of the air conditioner is lowered, and the electric control valve connected to the air outlet of the area where the temperature has dropped to the required temperature is closed, and the air outlet of the area is stopped. In this way, the area that cannot be cooled down can be cooled quickly.

[0073] In some examples, the temperature distribution unit calculates the temperature distribution and cooling requirements of the computer room based on the fluid dynamics model and the heat transfer model, and feeds the calculation results back to the central control module, specifically including:

[0074] S221: Collect temperature information of the computer room in advance and establish a fluid dynamics model.

[0075] Specifically, the temperature information in the current computer room is collected by the central control module. The central control module can collect the temperature information of the computer room through the infrared detection module or by analyzing the stored historical temperature information. According to the temperature information of the computer room, the temperature distribution unit establishes a fluid dynamics model. When establishing the fluid dynamics model, the finite element method can be used for calculation, and the data set of the temperature information is substituted into the model for verification and model optimization, and finally the fluid dynamics model is determined. Among them, the finite element method is a numerical technique for solving the approximate solution of the boundary value problem of partial differential equations. The entire solution domain is divided into a finite number of non-overlapping units, and some suitable nodes are selected in each unit as the interpolation points of the solution function. The variables in the differential equation are rewritten into linear expressions composed of the node values ​​of each variable or its derivative and the selected interpolation function, and then the differential equation is discretely solved by means of the variational principle or the weighted residual method. It can be understood that the use of the finite element method to determine the fluid dynamics model in the embodiment of the present disclosure is only an example, and is not specifically limited. Technicians in the relevant field can choose other methods to determine the fluid dynamics model according to actual conditions.

[0076] S222: Use fluid dynamics models to simulate the flow of air in a computer room.

[0077] Specifically, the temperature distribution unit uses a fluid dynamics model to simulate the flow of air in the computer room, which is used to subsequently determine the working mode of the air conditioner.

[0078] S223: Use the heat transfer model to calculate the thermal conductivity of the human body, server and equipment, and use the fluid dynamics model to calculate the cooling time and optimal cooling temperature in the current computer room.

[0079] Specifically, the temperature distribution unit uses a heat transfer model to calculate the thermal conductivity of the human body, servers, and equipment, and then determines the temperature distribution in the computer room. It combines the fluid dynamics model to calculate the cooling time and optimal cooling temperature in the current computer room, and uploads the calculation results to the central control module. The central control module controls the start of the air conditioner and selects a preset air conditioner operating mode.

[0080] In some examples, the color tracking unit analyzes the real-time temperature information of each area of ​​the room through color space conversion, threshold setting, and color tracking, and feeds the analysis results back to the central control module, including:

[0081] S421: Perform color space conversion on the real-time temperature information of each area in the computer room sent by the infrared detection module to determine the HSV color image of each area in the computer room.

[0082] Specifically, the color tracking unit receives the real-time temperature information of each area of ​​the computer room sent by the infrared detection module. The temperature information at this time is represented by the RGB color space. Due to the wide variety of colors in the RGB color space, direct color tracking may be difficult. Therefore, the image is usually converted from the RGB color space to other color spaces first; for example: HSV color space. The RGB color space includes three channels: red, green, and blue. The HSV color space includes hue, saturation, and brightness. Therefore, converting the RGB color space to the HSV color space can improve the accuracy of color tracking. At this point, the HSV color images of each area of ​​the computer room can be obtained for subsequent analysis. The computer room is divided into several areas, and there are several HSV color images.

[0083] S422: setting range thresholds of red hue, saturation and brightness in the HSV color image to separate red areas in the HSV color image of each region.

[0084] Specifically, the color tracking unit sets thresholds according to the hue, saturation, and brightness range of red. These thresholds will be used to distinguish red from other colors. The color tracking unit performs color tracking pixel by pixel. When the hue, saturation, and brightness values ​​of a pixel fall within the set threshold range, the pixel is considered to be red. For example, the color tracking unit traverses all pixels. When a pixel falls within the threshold range of hue, saturation, and brightness, it is determined to be red, and the pixel value of this pixel is set to 1, and the pixel values ​​of other pixels that do not fall within the threshold range are set to 0.

[0085] S423: Analyze the temperature information of the computer room area corresponding to the HSV color image according to the range of the red area.

[0086] Specifically, the color tracking unit analyzes the temperature information of each area of ​​the computer room according to the range size of the red area in the HSV color image, that is, the number of pixels with a pixel value of 1.
