Description

Technical Field

[0001] The present invention relates to the field of automatic temperature control technology, and more specifically, to an advanced automatic temperature control method, system, terminal and storage medium for equipment. Background Art

[0002] Existing switch equipment cooling methods are divided into two categories: natural cooling without fans and active cooling with fans. Among them, active cooling with fans is divided into two categories: adjustable speed fans and non-adjustable speed fans. In the adjustable speed fan design, conventional fan speed control and cooling strategies are roughly divided into 2-3-4 fan speed designs.

[0003] At present, the mainstream strategy of fan speed regulation of existing switches on the market is roughly based on the fixed classification of CPU / sensor temperature corresponding to the speed regulation. The classification strategy is to compare the CPU / sensor temperature at different fan speeds in a normal temperature environment of 25 degrees, and find a temperature that meets the normal operation of the system to set the corresponding gear. Or take the high temperature environment of 45 degrees as the benchmark value for measurement, and compare the CPU / sensor temperature at different speeds to set the corresponding gear. This strategy of setting the gear based on a fixed ambient temperature has great disadvantages. For example, if the gear is designed based on a 25-degree environment, the temperature of the device corresponding to the overall speed range will be higher than the normal temperature when the device is in a high temperature environment. In this case, the low gear is useless, and the speed strategy will intervene in the high speed gear too early, resulting in a problem of reduced energy efficiency. For example, if the gear is designed based on a 45° environment as the benchmark, the overall temperature of the device is lower than the benchmark when the device is in a low temperature environment, the high gear of the device will be useless, and the temperature corresponding to the fixed low gear will appear to be too surplus, reducing the energy efficiency of the device. This design strategy causes the fan speed to switch continuously in certain stable states when the ambient temperature changes, causing the noise frequency to change alternately and affecting the user experience. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an advanced automatic temperature control method for equipment in view of the above-mentioned defects of the prior art, and also provide an advanced automatic temperature control system for equipment, an advanced automatic temperature control terminal for equipment and a computer-readable storage medium.

[0025] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the protection scope of the present invention.

[0026] The advanced automatic temperature control method for a device in a preferred embodiment of the present invention, as Figure 1 shown, and referring to Figure 2 simultaneously, includes the following steps:

[0027] S01: Record the detected temperatures of a set chip at multiple different rotational speeds of a fan in multiple different ambient temperatures, calculate the average value of the detected temperature changes at multiple different ambient temperatures corresponding to adjacent rotational speed changes, and map out a change table of the fan rotational speed change and the average value change of the detected temperature;

[0028] S02: Set a reference temperature for the set chip, and this reference temperature can ensure the normal and stable operation of the set chip;

[0029] S30: Detect the actual temperature of the set chip during operation, query the change table according to the actual temperature and the temperature difference between the actual temperature and the reference temperature, obtain the corresponding fan rotational speed adjustment ratio, and perform fan rotational speed adjustment after summing this rotational speed adjustment ratio and the initial rotational speed of the fan;

[0030] Applying the method of the present application, the finer the rotational speed grading in the mapped change table, the smoother the adjustment process, and the closer it can approach stepless speed regulation and temperature regulation. This speed regulation strategy does not change with the change of the external temperature, has accurate speed regulation, and far surpasses the traditional speed regulation strategy in terms of energy efficiency ratio control.

[0031] Specifically, based on the mapping table obtained by the above method of the present application, average the interference factors of the external environment, and then obtain the mapping table of the temperature change corresponding to the rotational speed change, that is, it reflects that when the fan starts from a set starting rotational speed and the rotational speed increases by a certain value (such as 5% or 10%, etc.), the corresponding average temperature starts to decrease by the corresponding value from a corresponding starting temperature (the average decrease is not constant); then conduct actual measurement, obtain the rotational speed increase ratio value on the mapping table according to the change relationship between the actual measurement and the reference value, and then increase the ratio value on the initial rotational speed;

[0032] The increased ratio value usually does not exactly correspond to the value in the mapping table. At this time, it is necessary to take the larger value of the interval. For example, the rotational speed increase gears are 5% - 10% - 15%. If it is in the interval of 10% - 15%, then take the maximum value of 15% to ensure the heat dissipation effect;

[0033] Preferably, the set chip is a CPU, and the temperature detection of the set chip is carried out through a temperature sensor; it can also be other chips as required; similarly, according to the actual application scenario of the chip, the reference temperature value to be set is also different.

[0034] An example of fan rotational speed adjustment is Figure 2 as shown, and the rotational speed ratio of the fan is adjusted correspondingly according to the detected temperature difference;

[0035] An advanced automatic temperature control system for a device, used to implement the advanced automatic temperature control method for a device as described above, such as Figure 3As shown in the figure, it includes an analog measurement unit 100, a reference temperature setting unit 101, and a fan adjustment unit 102;

[0036] The analog measurement unit 100 is used to record the detection temperature of a set chip at multiple different environmental temperatures when the fan is at multiple different set rotational speeds, calculate the average value of the detection temperature changes at multiple different environmental temperatures corresponding to adjacent rotational speed changes, and map a change table of the fan rotational speed change and the average value change of the detection temperature;

[0037] The reference temperature setting unit 101 is used to set a reference temperature for the set chip, and this reference temperature can ensure the normal and stable operation of the set chip;

[0038] The fan adjustment unit 102 is used to detect the actual temperature of the set chip during operation, query the change table according to the actual temperature and the temperature difference between the actual temperature and the reference temperature, obtain the corresponding fan rotational speed adjustment ratio, and perform fan rotational speed adjustment after summing the rotational speed adjustment ratio and the initial rotational speed of the fan.

[0039] Applying the method of the present application, the finer the rotational speed grading in the mapped change table, the smoother the adjustment process, and the closer it can approach stepless speed regulation and temperature control. This speed regulation strategy does not change with external temperature changes, has precise speed regulation, and far exceeds the traditional speed regulation strategy in terms of energy efficiency ratio control;

[0040] Preferably, when the fan adjustment unit 102 determines the fan rotational speed adjustment ratio, it selects the highest value in the corresponding fan rotational speed change interval in the change table.

[0041] Preferably, the set chip is a CPU, and temperature detection of the set chip is performed through a temperature sensor.

[0045] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present invention.
