Description of the Invention: [Technical Field of the Invention] The present invention relates to a fan speed, and is a more detailed system and method according to a preset two == method. Degree 1^ phase fan speed control [prior art] With the rapid development of computer technology, and the indispensability of work, it has become the practice of people's daily life ^ /,, due to the continuous improvement of computer performance, the handling of 1 It has become a resurgence, and it has also increased relatively. #央processed the early 70's operation speed and heat source, and then it will be abundance... and it will cause a big smashing machine.疋' Air-cooled cooling system is the most popular film in the industry. 放π人Μ See the heat release method, fan plus 埶 = structure: air-cooled: device, which is simple in structure, low in price, The advantages of $ search are widely used in computer equipment and: & In order to eliminate the heat source of the system as soon as possible, the amount of heat is reduced: =: The speed of the cooling fan is low. However, the acceleration is not good, and the fan is prone to noise during the rotation. In addition, the fan is often in high life. kI is sorrowful, and it also affects its use of life as the solution to the above problem. At present, there is a fan speed control technology that adds temperature-sensing cracking and can be changed according to system temperature and fan speed. It is matched with at least one upper and lower fan. As shown in Figure 1, the wind used in Gomming "^ is not used to control the fan with a temperature threshold. 18150 (Revised) 5 1262648 Speed ^Remain - Lid Β Not thinking about h shape. As shown in the figure, the temperature change curve 10 is drawn; ri has two speed fan electronic devices i (such as computer mainframe, laptop ^ 艮 ~, etc.) due to system heat source heat caused by system temperature changes, 疋 me / phoenix The value of the product boundary value Ct, when the system temperature exceeds the critical value of the temperature, = fan turn: 4 control device adjusts the fan speed to - high speed, until the temperature drop: below the temperature threshold, the fan speed control device adjusts the fan speed Low speed, as shown in the fan speed change line 12 in the figure, but this method has disadvantages, especially when the system temperature is vibrating near the temperature threshold, the fan speed control device must quickly adjust the fan speed to meet the need for frequent adjustment. The reverse speed of the fan reduces the life of the fan. In order to solve the above-mentioned technical deficiencies, an improvement scheme is proposed, such as the second = no-thickness is added to the critical temperature value Ct to add a small temperature change amount to form another L-bound grading value ct!, from the critical temperature value Ct and the critical The temperature value ct] forms a critical temperature interval, that is, the upper limit is set as the critical temperature value 〇, and the lower limit is the difference between the critical temperature value Ct minus the small temperature change amount At (ie, the criticality value Ct i ), when the system temperature exceeds the When the temperature threshold value Ct, the fan speed control device adjusts the fan speed to a high speed, and the temperature is reduced to the critical temperature Ct minus the difference of the small temperature change amount At (ie, the critical temperature ct). Below, the fan speed control device adjusts Fan speed to low speed. After the temperature change amount At is added, the fan can be kept stable for a long time, but this method does not completely solve the problem that the temperature oscillation frequently changes due to temperature oscillation, as shown in the figure when the system temperature change curve 20 is at the critical temperature value ct When the oscillation is nearby, the fan speed adjustment will still occur, and the fan speed change line 22 will generate a sudden change in speed at the corresponding position 22〇, which will seriously deplete the wind 18150 (corrected) 6 1262648 fan life. " To this end, how to provide a fan speed control system and method, in order to change the lack of t-track technology, so that the fan speed change is not affected by the system temperature, the driver's life is extended and the system environmental noise is reduced. SUMMARY OF THE INVENTION 9 In addition to the shortcomings of the above-mentioned prior art, the main object of the present invention is to provide a fan speed control system which can avoid a drastic change in the rotational speed of the system. Still another object of the present invention is to provide a fan speed control system that achieves power saving and extended fan life. To achieve the above objective, the fan speed control system of the present invention is configured to set a fan to adjust the temperature of the electronic device, which at least includes: using == at least the temperature is higher than the at least one temperature interval, and the temperature is lower than the temperature interval. The corresponding second fan of the fan is two: two: Γ 杈 杈 group ' is used to record the speed of the fan speed when the fan is operating and output: two temperature modules obtained after adjusting the temperature of the heat generating material; and used to determine the temperature Whether the temperature parameter output by the F-group belongs to the temperature interval recording mode, the judgment module of the recorded temperature range, and the speed of the operation is performed, otherwise the temperature parameter is maintained according to the temperature. The fan rotation degree interval recording module degree parameter is determined from the temperature interval recording module = when it is different from the temperature range, if it is lower than the temperature range == whether the temperature parameter is lower than the J, the fan speed is Decrease and update the fan speed recorded by the speed recording module with the speed of the 18150 (corrected) 7 1262648. Otherwise, the fan is recorded in the speed recording module. The fan speed is operated; if the fan speed is the same, the phase is recorded from the temperature interval according to the temperature parameter: the group determines whether the temperature parameter is souther than the temperature range. If the temperature is south, the fan speed is increased. And updating the fan speed recorded by the rotational speed recording module at the rotational speed, and vice versa, causing the fan to operate with the fan rotational speed recorded in the rotational speed recording module. The fan speed control method of the present invention is applied to an electronic device for setting a fan to adjust temperature, and at least includes the following steps: causing the electronic device to record at least a first fan speed and a low temperature corresponding to a temperature higher than at least one temperature interval. The second rotation speed of the fan corresponding to the temperature interval, and the fan rotation speed is recorded when the fan is operated; the electronic device detects the temperature obtained by the fan adjusting the temperature of the heat generating material and outputs the temperature parameter; and the electronic device is Determining whether the output temperature parameter belongs to the recorded temperature range, and if so, the fan maintains the same speed for operation; otherwise, the temperature parameter is used to determine whether the corresponding fan speed is the same as the recorded fan speed. When the fan speed is different, it is determined whether the temperature parameter is lower than the temperature interval according to the temperature parameter. If the temperature is lower than the temperature interval, the fan speed is decreased and the fan speed recorded in the electronic device is updated at the speed, otherwise, Let the fan perform the fan speed recorded in the electronic device If the fan speed is the same, it is determined whether the temperature parameter is higher than the temperature range according to the temperature parameter. If the temperature is higher than the temperature range, the fan speed is increased and the speed is updated and recorded in the electronic device. The fan speed, on the other hand, causes the fan to operate at the fan speed recorded in the 1826648 device of the electronic 8 18150 (Revised). Fortunately, the father in the kitchen of the $ $ soil control system and method control technology 'the temperature fluctuation near the fan speed of the invention caused by the wind === degree interval' to avoid the shortcomings of the critical temperature technology, the evaluation of the idler to l ^ white Know and reduce system environmental noise. The embodiment of the present invention is described by a specific specific example. The person skilled in the art can understand the other advantages and effects of the present invention disclosed in the present specification. . The present invention may be carried out or applied by various other embodiments, and various modifications and changes can be made without departing from the spirit and scope of the invention. Shishi? The figure shown in Fig. 3 is used to illustrate the fan speed control system of the present invention. As shown in the figure, the fan speed control system includes a temperature debt test module, a temperature interval recording module 31, a rotational speed group, and a determination module 33, and is connected to the fan body 4. The wind, the tanning system, and the charging system are provided in an electronic device that uses a fan to dissipate heat to adjust the ambient temperature. In the present embodiment, the electronic device is, for example, a servo. And the fan body 4 has a low-order rotational speed and a high-speed rotational speed: the temperature detecting module 3 is configured to detect the temperature of the fan after the temperature is processed by the heat generating object (for example, a central processing unit, etc.) In the present example, the temperature measurement module is a temperature sensor, and the system environment temperature under the operation condition of the feeding device 9 18150 (corrected) 1262648 is immediately transmitted to the judgment module 33. The temperature interval recording module 31 is a temperature range of the fan rotation speed. In the present embodiment, the number of corresponding temperature values Ct is θ π , for example, the threshold value Ct is set to 50 C and the minute temperature is set in advance. The amount of change ^ is > when the dish is higher than (4), the fan speed control system, system 3 provides high speed operation of body 4, when the system temperature is lower than 47t day: ^ fan temperature value Ct blood tiny, w _ mother ·, inch (P the g product boundary 被, the difference between the small amount of change At), the system 3 will control the fan body 4 to provide low-speed operation control temperature zone strict 1 47〇C Xiao 5〇t production , and the fan speed of the target industry is determined, more peaceful, / / / according to the purpose The critical temperature interval of the two systems should be incorporated into the low speed range, and the current;.;:,, high speed, the foot speed, and the fan speed of the fan should be merged into the high speed range. The speed recording module 32 is used to record the wind catch, and then it is an important basis for judging the operation of the module 33. The operation of the judgment module 33 is used for miscellaneous offerings: #, w浩 a measured H ^ 乂 (4) The ▲ degree detection module 30 currently corresponds to the number of 皿 皿 所 according to the aforementioned quotient of the temperate Bamen...
