[0002] In today's computers or other computing systems, fans are often used to dissipate heat. In order to prevent the fan from being damaged by overcurrent, an overcurrent protection circuit is needed to monitor the fan's current to avoid excessive current caused by abnormal load during operation. In terms of design, overcurrent protection circuits are often used in the fan's power supply circuit to ensure that the fan can operate within a safe current range and avoid other system failures caused by excessive current. However, this protection mechanism cannot detect the problem of abnormal operation of the fan itself, and can only effectively prevent the current from exceeding the design range. Summary of the invention

The temperature sensor is used to sense the system temperature. The first computing element is used to determine the matching result between the current operating parameters of the fan and the power parameters for controlling the fan, compare the system temperature with the preset temperature to generate a comparison result, and control the fan, the system switch element or the alarm element according to the matching result and the comparison result.

[0006] With the above structure, the computing system and control method thereof disclosed in the present invention can control the fan, system switch element or warning element in the computing system through the matching results between the fan-related parameters and the comparison results between the sensed temperature and the preset temperature, thereby avoiding permanent system failure due to fan failure.

[0022] The detailed features and advantages of the present invention are described in detail in the following embodiments, and the contents are sufficient to enable ordinary technicians in the field to understand the technical content of the present invention and implement it accordingly. According to the contents, protection scope and drawings disclosed in this specification, ordinary technicians in the field can easily understand the relevant purposes and advantages of the present invention. The following examples are to further illustrate the viewpoints of the present invention in detail, but are not intended to limit the scope of the present invention in any way.

[0023] Please refer to Figure 1 , Figure 1 FIG. 1 is a functional block diagram of a computing system according to an embodiment of the present invention. Figure 1 As shown, the computing system 1 includes a fan 11, a system switch element 12, an alarm element 13, a temperature sensor 14 and a first computing element 15. The fan 11, the system switch element 12, the alarm element 13 and the temperature sensor 14 are connected to the first computing element 15 by wire or wirelessly.

[0024] The fan 11 is used to provide a heat dissipation function. Specifically, the fan 11 can be a fan for cooling a central processing unit, a graphics processing unit, a housing, a light-emitting element or other heating elements. The system switch element 12 is used to control the opening or closing of the system power supply. The warning element 13 is used to send a warning signal to warn the user under certain circumstances. For example, the warning element 13 can be an output device such as an indicator light, a speaker device, a liquid crystal display, or a wired or wireless communication port to output the warning signal to the connected electronic device. The temperature sensor 14 is used to sense the temperature. Specifically, the temperature sensor 14 can be set corresponding to the fan 11 to sense the temperature of the main heat dissipation object of the fan 11. The main heat dissipation object is, for example, the aforementioned central processing unit, graphics processing unit, housing, light-emitting element, etc. The first operation element 15 is used to control the operation of the elements of the computing system 1. Specifically, the first operation element 15 can be used to determine the matching results between different fan-related parameters and compare the temperature sensed by the temperature sensor 14 with the preset temperature to generate a comparison result, and control other elements of the computing system 1 according to the matching result and the comparison result. Further, the first operation element 15 can be a microcontroller.

[0025] The operation of the first operation element 15 can determine the matching result between the current operation parameters of the fan 11 and the power parameters controlling the fan 11, and has corresponding control mechanisms for different matching results, which is equivalent to the function of an overcurrent protection element. Accordingly, in some embodiments, an overcurrent protection element may not be provided between the fan 11 and the system power supply, thereby reducing the system construction area and cost.

[0026] Please refer to Figure 2 , Figure 2 FIG. 1 is a flow chart of a computing system control method according to an embodiment of the present invention. Figure 2 As shown, the computing system control method includes step S11: controlling the fan according to the power parameter and obtaining the current operating parameter of the fan; step S12: obtaining the system temperature; step S13: determining the matching result between the current operating parameter and the power parameter; step S14: comparing the system temperature with the preset temperature to generate a comparison result; and step S15: controlling the fan, the system switch element or the warning element according to the matching result and the comparison result. The above steps can be performed by Figure 1The operation system 1 shown in the figure is executed, and the following is exemplarily performed as follows Figure 1 The operation system 1 shown is used to illustrate the implementation of each step.

[0027] In step S11, the first operation element 15 controls the fan 11 according to the power parameter and obtains the current operation parameter of the fan 11. Specifically, the power parameter may be the duty cycle of the pulse width modulation (PWM) signal of the first operation element 15 controlling the fan 11; the operation parameter may be the speed at which the fan 11 operates in response to the control signal received from the first operation element 15. In one embodiment, the power parameter is directly provided to the fan 11 by the first operation element 15. As for the rotation speed of the fan 11, it can be directly obtained from the fan 11 by the first operation element 15, instead of being obtained from the power supply path between the fan 11 and the system power supply.

[0028] In step S12, the first computing element 15 obtains the system temperature. Specifically, the first computing element 15 senses the system temperature through the temperature sensor 14 to obtain the system temperature. The system temperature may be the temperature of the CPU, GPU, housing, light emitting element or other heating element.

[0029] In step S13, the first operation element 15 determines the matching result between the current operation parameter and the power parameter of the fan 11. Specifically, the first operation element 15 can determine the matching result between the current operation parameter and the power parameter by using a pre-stored correspondence relationship, and the matching result can indicate a normal match, a first matching degree, or a second matching degree.

[0030] In step S14, the first operating element 15 compares the system temperature with the preset temperature to generate a comparison result. Specifically, the first operating element 15 obtains the comparison result by comparing whether the system temperature is greater than the preset temperature.

[0031] In step S15, the first operation element 15 controls the fan, the system switch element or the warning element according to the matching result and the comparison result. Specifically, when the matching result of step S13 indicates the first matching degree and the comparison result of step S14 indicates that the system temperature is not greater than the preset temperature, the first operation element 15 controls the warning element 13 to output a warning signal; when the matching result of step S13 indicates the second matching degree and the comparison result of step S14 indicates that the system temperature is not greater than the preset temperature, the first operation element 15 stops the operation of the fan 11; when the comparison result of step S14 indicates that the system temperature is greater than the preset temperature, the first operation element 15 stops the operation of the fan 11 and turns off the system switch element 12. In other words, when the system temperature is greater than the preset temperature, no matter whether the matching result of the fan's current operating parameters and the power parameters indicates the first or second matching degree, the first operation element 15 stops the operation of the fan 11 and turns off the system switch element 12.

[0032] In addition, it should be noted that Figure 2 The execution order of steps S11 to S14 is illustrated only for example. Except that step S11 must be executed before step S13 and step S12 must be executed before step S14, the execution order of steps S11 to S14 can also be executed in the reverse order or simultaneously, which is not limited by the present invention.

[0033] For further explanation of step S13, please refer to Figure 1 and Figure 3 ,in Figure 3 The flowchart of generating a matching result of a computing system control method according to an embodiment of the present invention is shown.

[0034] like Figure 3 As shown, Figure 2 Step S13 may include step S131: obtaining standard operating parameters corresponding to power parameters from a pre-stored correspondence; step S132: determining whether the difference between the current operating parameters and the standard operating parameters is greater than a first preset threshold; when the determination result of step S132 is "no", executing step S133: generating a matching result indicating a normal match; step S134: determining whether the difference between the current operating parameters and the standard operating parameters is greater than a second preset threshold; when the determination result of step S135 is "no", executing step S133: generating a matching result indicating a first matching degree; and when the determination result of step S132 is "yes", executing step S136: generating a matching result indicating a second matching degree.

[0035] In step S131, the first operation element 15 obtains a standard operation parameter corresponding to the power parameter from the pre-stored correspondence. Specifically, the pre-stored correspondence includes a plurality of pre-stored power parameters and a plurality of pre-stored operation parameters respectively corresponding to the plurality of pre-stored power parameters, and the standard operation parameter is one of the plurality of pre-stored operation parameters. For example, the pre-stored correspondence may be a lookup table.

[0036] In step S132, it is determined whether the difference between the current operating parameter and the standard operating parameter is greater than a first preset threshold. Specifically, when the difference between the current operating parameter and the standard operating parameter is not greater than the first preset threshold, the first operating element 15 will execute step S133; when the difference between the current operating parameter and the standard operating parameter is greater than the first preset threshold, the first operating element 15 will execute step S134.

[0037] In step S133 , a matching result indicating a normal match is generated. Specifically, when the difference between the current operating parameter and the standard operating parameter is not greater than the first preset threshold, the fan 11 is in a normal state.

[0038] In step S134, the first operation element 15 determines whether the difference between the current operation parameter and the standard operation parameter is greater than the second preset threshold. Specifically, when the difference between the current operation parameter and the standard operation parameter is not greater than the second preset threshold, the first operation element 15 will execute step S135; when the difference between the current operation parameter and the standard operation parameter is greater than the second preset threshold, the first operation element 15 will execute step S136.

[0039] In step S135 , the first computing element 15 generates a matching result indicating a first matching degree. Specifically, the matching result may be a difference between the current operating parameter obtained by the first computing element 15 from the fan 11 and the standard operating parameter.

[0040] In step S136, the first operation element 15 generates a matching result indicating a second matching degree. Specifically, the second matching degree is lower than the first matching degree. In addition, the first matching degree is lower than a normal match.

[0041] Further, the first operation element 15 can pre-store a normal value lookup table, and can preset a normal match indicating that the difference between the current operation parameter and the standard operation parameter is less than a first preset ratio / value, the first match degree indicates that the difference between the current operation parameter and the standard operation parameter is not less than the first preset ratio / value and less than a second preset ratio / value, and the second match degree indicates that the difference between the current operation parameter and the standard operation parameter is not less than the second preset ratio / value. The following is an example of a plurality of operation conditions for illustration, the lookup table is exemplarily presented as Table 1, and the normal match and the second match degree are, for example, divided by 1.05 times the preset ratio, and the first and second match degrees are, for example, divided by 2 times the preset ratio. When the first operation element 15 executes step S131, the standard operation parameter corresponding to the power parameter can be obtained from the lookup table, the power parameter corresponds to the duty cycle of the fan provided in Table 1, and the standard operation parameter corresponds to the fan speed per minute in Table 1. In addition, in addition to referring to the preset system temperature range, the fan speed per minute and the fan duty cycle, the first operating element 15 can also include reference to the temperature sensor value of the sensed ambient temperature, compare the temperature sensor value of the sensed ambient temperature with the preset ambient temperature range in the lookup table, and comprehensively determine whether the current speed of the fan 11 is normal based on the temperature sensor value of the sensed ambient temperature. Specifically, when the value is not greater than the upper limit of the preset ambient temperature range, the fan speed per minute is reduced and the fan duty cycle is provided. When the value is greater than the upper limit of the preset ambient temperature range, the fan speed per minute is increased and the fan duty cycle is provided. The first operating element 15 determines whether the speed of the fan 11 is normal according to the above-mentioned updated standard.

[0042] Table 1

[0043]

[0044] Assuming that the temperature sensed by the temperature sensor 14 is 94 degrees, the current speed of the fan 11 is 9,200 RPM, and the duty cycle is 100%, the difference between the current speed of the fan 11 and the fan speed corresponding to the duty cycle of 100% in the lookup table is not less than 1.05 times and less than 2 times. At this time, the first operating element 15 can use the pre-stored lookup table to determine that the matching result is the first matching degree. The comparison result is that the system temperature is not greater than the upper limit of the preset system temperature range (the aforementioned preset temperature), then the first operating element 15 can control the warning element 13 to output a warning signal.

[0045] Assuming that the temperature sensed by the temperature sensor 14 is 65 degrees, the current speed of the fan 11 is 11,000 RPM, and the duty cycle is 50%, the current speed of the fan 11 is 2.2 times different from the fan speed corresponding to the duty cycle of 50% in the lookup table. At this time, the first operating element 15 can use the pre-stored lookup table to determine that the matching result is a second matching degree in which the fan speed differs by more than 2 times. If the comparison result is that the system temperature is not greater than the upper limit of the preset system temperature range, the first operating element 15 can stop the operation of the fan 11.

[0046] Assuming that the temperature sensed by the temperature sensor 14 is 96 degrees, the current speed of the fan 11 is 1,000 RPM, and the duty cycle is 100%, the current temperature of the fan 11 is 2 degrees greater than the preset system temperature. At this time, the first operational element 15 can use the pre-stored lookup table to determine that the comparison result is that the system temperature is greater than the upper limit of the preset system temperature range. The first operational element 15 can then stop the operation of the fan 11 and turn off the system switch element 12.

[0047] Assuming that the value of the temperature sensor sensing the ambient temperature is 43 degrees, the temperature sensor 14 senses a temperature of 95 degrees, the current speed of the fan 11 is 10,001RPM, and the duty cycle is 100%, the sensed ambient temperature is not greater than the upper limit of the preset ambient temperature range, then the first operating element 15 will reduce the fan speed per minute in the lookup table and the duty cycle provided to the fan, and the current speed of the fan 11 and the fan speed corresponding to the duty cycle of 100% in the lookup table differ by a factor of not less than 1.05 times and less than 2 times. At this time, the first operating element 15 can use the pre-stored lookup table to determine that the matching result is the first matching degree, and the comparison result is that the system temperature is not greater than the upper limit of the preset system temperature range, then the first operating element 15 can control the warning element 13 to output a warning signal.

[0048] The values ​​recorded in the above-mentioned lookup table and the values ​​set for the matching degree classification criteria are only examples, and can be designed according to actual needs, and the present invention is not limited thereto.

[0049] Please refer to Figure 4 , Figure 4 FIG. 1 is a functional block diagram of a computing system according to another embodiment of the present invention. Figure 4 As shown, the computing system 1' comprises a fan 11, a system switch element 12, an alarm element 13, a temperature sensor 14, a first computing element 15 and a second computing element 16. The second computing element 16 is connected to the first computing element 15 by wire or wireless means. The functions and connection relationships of the fan 11, the system switch element 12, the alarm element 13, the temperature sensor 14 and the first computing element 15 are the same as those of Figure 1The fan 11, the system switch element 12, the warning element 13, the temperature sensor 14 and the first computing element 15 included in the computing system 1 are not described in detail herein.

[0050] The second computing element 16 is used to execute the preset application program. For example, the second computing element 16 can be a central processing unit or a graphics processor. In this embodiment, the computing system 1' can execute the aforementioned Figure 2 In steps S11 to S15, a step of evaluating the degree of fan degradation may be further performed.

[0051] Please refer to Figure 5 , Figure 5 FIG. 1 is a flow chart of evaluating the degree of fan degradation of a computing system control method according to an embodiment of the present invention. Figure 5 As shown, the computing system control method for evaluating the degree of fan degradation may include step S21: obtaining a plurality of system parameters when the computing system only executes a preset application; step S22: obtaining the degree of fan degradation using the plurality of system parameters and a pre-trained model; and step S23: controlling the warning element to output a signal indicating the degree of degradation. The above steps may be performed by Figure 4 The operation system 1' shown in the figure performs the following exemplary operation: Figure 4 The operation system 1 ′ is shown to illustrate the implementation of each step.

[0052] In step S21, the first computing element 15 or the second computing element 16 obtains a plurality of system parameters when the computing system executes only the preset application program. Specifically, the plurality of system parameters may include the rotation speed of the fan 11, the value sensed by the temperature sensor 14, the value of the temperature sensor sensing the ambient temperature, the power values ​​of the plurality of fans corresponding to different supply voltages, the power value of the CPU, the power value of the panel, and the brightness value. Furthermore, the temperature sensor sensing the ambient temperature may be disposed at a position away from the main heat dissipation object so as to sense the real temperature of the environment to which it belongs without being affected by the temperature of the main heat dissipation object.

[0053] In step S22, the first operation element 15 or the second operation element 16 obtains the degree of degradation of the fan 11 using the plurality of system parameters and the pre-trained model. Specifically, the first operation element 15 or the second operation element 16 obtains the degree of degradation of the fan 11 by inputting the plurality of system parameters into the pre-trained model. Further, the pre-trained model can be generated by using the plurality of system parameter data in normal conditions and fault conditions, marking the probability of the fan 11 requiring maintenance at one or more time points (e.g., one week later and two weeks later) according to the different conditions corresponding to the data, and inputting the labeled data as training data into a neural network architecture such as a multi-layer perceptron, a convolutional neural network, or a recurrent neural network that can handle large amounts of data and complex nonlinear problems for training.

[0054] In addition, the first operating element 15 or the second operating element 16 can further utilize multiple system parameters and other pre-trained models when the operating system only executes the preset application to obtain the degree of degradation of other system components. The construction method of the pre-trained model is the same as the aforementioned fan degradation degree judgment model, which will not be repeated here. For example, when the operating system only executes the preset application and the fan is in a full load state (for example, the speed is 100%), if the sensing value of the temperature sensor that senses the ambient temperature falls within the first temperature range (for example, 60 degrees Celsius), the first operating element 15 or the second operating element 16 can determine that the thermal pad or heat pipe is normal; if the sensing value of the temperature sensor that senses the ambient temperature falls within the second temperature range (for example, 25 degrees Celsius), the first operating element 15 or the second operating element 16 can determine that the thermal pad or heat pipe is failed.

[0055] In step S23, the first computing element 15 controls the warning element 13 to output a signal indicating the degree of degradation. Specifically, the first computing element 15 obtains the degree of degradation of the fan 11 outputted by the first computing element 15 or the second computing element 16 after executing the pre-trained model, and controls the warning element 13 to output a signal indicating the degree of degradation.

[0056] In one embodiment, after the first computing element 15 obtains a plurality of system parameters when the computing system only executes a preset application, the plurality of system parameters are input into a pre-trained model to obtain the degree of degradation of the fan 11, and the alarm element 13 is controlled to output a signal indicating the degree of degradation. In another embodiment, after the second computing element 16 obtains a plurality of system parameters when the computing system only executes a preset application, the plurality of system parameters are input into a pre-trained model to obtain the degree of degradation of the fan 11, and a command is sent to the first computing element 15 to control the alarm element 13 to output a signal indicating the degree of degradation.

[0057] With the aid of the above structure, the computing system and control method thereof disclosed in the present invention can control the fan, system switch element and warning element in the computing system through the matching results between the fan-related parameters and the comparison results between the sensed temperature and the preset temperature, thereby avoiding permanent system failure due to fan failure. In addition, compared with the use of a traditional overcurrent protection circuit to prevent the fan from failing due to excessive current, the computing system and control method thereof disclosed in the present invention can replace the overcurrent protection circuit to provide the function of preventing the fan from failing due to excessive current, thereby saving board area and reducing costs, and can solve the problem of abnormal operation of the fan itself that cannot be handled by the overcurrent protection circuit. In addition, by controlling the fan, system switch power supply or warning element according to the matching results and comparison results, the computing system and control method thereof disclosed in the present invention can further use the obtained matching results and comparison results to establish more mechanisms for detecting fan failure and corresponding measures for fan failure, and use more different methods to prevent fan failure.
