Description

Computing system and control method thereof

The present invention relates to a computing system control method.

In today's computers or other computing systems, fans are often used to dissipate heat. In order to prevent fans from being damaged by overcurrent, overcurrent protection circuits are needed to monitor the current of the fan to avoid excessive current caused by abnormal load during operation. In design, overcurrent protection circuits are often used in the power circuit of the fan 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 malfunctions of the fan itself, and can only effectively prevent the current from exceeding the design range.

In view of the above, the present invention provides a computing system and a control method thereof.

According to an embodiment of the present invention, a computing system control method includes controlling a fan according to power parameters and obtaining the current operating parameters of the fan; obtaining the system temperature; determining the matching result between the current operating parameters and the power parameters; comparing the system temperature with a preset temperature to generate a comparison result; and controlling the fan, a system switch element, or an alarm element according to the matching result and the comparison result.

According to an embodiment of the present invention, a computing system includes a fan, a system switch element, an alarm element, a temperature sensor and a first computing element, wherein the fan, the system switch element, the alarm element and the temperature sensor are respectively connected to the first computing element. 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.

Through the above structure, the computing system and control method disclosed in this case can control the fan, system switch components or warning components 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 using a traditional over-current protection circuit to prevent the fan from failing due to excessive current, the computing system and control method disclosed in this case can use the matching results and comparison results to implement multiple mechanisms to prevent fan failure, so as to replace the over-current protection circuit to provide the function of preventing the fan from failing due to excessive current, thereby saving the board area and reducing the cost, and can solve the problem of abnormal operation of the fan itself that cannot be handled by the over-current protection circuit.

The above description of the disclosed content and the following description of the implementation methods are used to demonstrate and explain the spirit and principle of the present invention, and provide a further explanation of the scope of the patent application of the present invention.

The detailed features and advantages of the present invention are described in detail in the following embodiments, and the contents are sufficient to enable any person skilled in the relevant art to understand the technical contents of the present invention and implement them accordingly. Moreover, according to the contents disclosed in this specification, the scope of the patent application and the drawings, any person skilled in the relevant art can easily understand the relevant purposes and advantages of the present invention. The following embodiments are to further illustrate the viewpoints of the present invention, but are not to limit the scope of the present invention by any viewpoint.

Please refer to FIG. 1, which is a functional block diagram of a computing system according to an embodiment of the present invention. As shown in FIG. 1, 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 wired or wireless means.

The fan 11 is used to provide a heat dissipation function. Specifically, the fan 11 can be a fan used to cool a central processing unit, a graphics processor, a casing, a light-emitting element or other heat-generating elements. The system switch element 12 is used to control the on or off of the system power. 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, 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 temperature. Specifically, the temperature sensor 14 can be set corresponding to the fan 11, and is used to sense the temperature of the main heat dissipation object of the fan 11. The main heat dissipation objects are, for example, the aforementioned central processing unit, graphics processor, housing, light-emitting element, etc. The first computing element 15 is used to control the operation of the elements of the computing system 1. Specifically, the first computing 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 computing element 15 can be a microcontroller.

The operation of the first computing element 15 can determine the matching result between the current operating 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 over-current protection element. Accordingly, in some embodiments, an over-current protection element may not be provided between the fan 11 and the system power supply, thereby reducing the system construction area and cost.

Please refer to FIG. 2, which is a flow chart of a computing system control method according to an embodiment of the present invention. As shown in FIG. 2, 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 executed by the computing system 1 shown in FIG. 1, and the implementation of each step is exemplarily described below using the computing system 1 shown in FIG. 1.

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

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 can be the temperature of the central processing unit, graphics processor, chassis, light-emitting element or other heating element.

In step S13, the first computing element 15 determines the matching result between the current operating parameter and the power parameter of the fan 11. Specifically, the first computing element 15 can determine the matching result between the current operating 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.

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

In step S15, the first computing 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 higher than the preset temperature, the first computing 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 higher than the preset temperature, the first computing element 15 stops the operation of the fan 11; 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 higher than the preset temperature, the first computing element 15 stops the operation of the fan 11; When the comparison result of S14 indicates that the system temperature is greater than the preset temperature, the first operating element 15 stops the operation of the fan 11 and turns off the system switch element 12. That is to say, when the system temperature is greater than the preset temperature, regardless of whether the matching result of the current operating parameters of the fan and the power parameters indicates the first or second matching degree, the first operating element 15 stops the operation of the fan 11 and turns off the system switch element 12.

It should also be noted that FIG. 2 only exemplarily illustrates the execution order of step S11 to step S14. Except that step S11 must be executed before step S13 and step S12 must be executed before step S14, the execution order of step S11 to step S14 can also be executed in the opposite order or simultaneously, which is not limited in this case.

To further explain step S13, please refer to FIG. 1 and FIG. 3, wherein FIG. 3 is a flow chart of generating a matching result of a computing system control method according to an embodiment of the present invention.

As shown in FIG. 3 , step S13 of FIG. 2 may include step S131: obtaining a standard operating parameter corresponding to the power parameter from a pre-stored correspondence relationship; step S132: determining whether the difference between the current operating parameter and the standard operating parameter 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: Determine whether the difference between the current operating parameter and the standard operating parameter is greater than a second preset threshold; When the determination result of step S135 is "No", execute step S133: generate a matching result indicating a first matching degree; and when the determination result of step S132 is "Yes", execute step S136: generate a matching result indicating a second matching degree.

In step S131, the first computing element 15 obtains the standard operating 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 operating parameters respectively corresponding to the plurality of pre-stored power parameters, and the standard operating parameter is one of the plurality of pre-stored operating parameters. For example, the pre-stored correspondence may be a lookup table.

In step S132, it is determined whether the difference between the current operating parameter and the standard operating parameter is greater than the 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 computing 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 computing element 15 will execute step S134.

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.

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

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.

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.

Further, the first computing element 15 may store a normal value lookup table, and may preset a normal match indicating that the difference between the current operating parameter and the standard operating parameter is less than a first preset magnification/value, a first match degree indicating that the difference between the current operating parameter and the standard operating parameter is not less than the first preset magnification/value and less than a second preset magnification/value, and a second match degree indicating that the difference between the current operating parameter and the standard operating parameter is not less than the second preset magnification/value. The following is an example of a plurality of operating conditions, and the lookup table is exemplarily presented as Table 1 below, and the normal match and the second match degree are, for example, divided by a preset magnification of 1.05 times as a basis, and the first and second match degrees are, for example, divided by a preset magnification of 2 times as a basis. When the first computing element 15 executes step S131, the standard operating 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 operating parameter corresponds to the speed of the fan per minute in Table 1. In addition, in addition to referring to the preset system temperature range, the fan speed per minute and the duty cycle of the fan, the first computing element 15 can also include reference to the temperature sensor value for sensing the ambient temperature, compare the temperature sensor value for sensing the 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 for sensing the ambient temperature. Specifically, when the value is not greater than the upper limit of the preset ambient temperature range, the fan speed per minute and the duty cycle of the fan are reduced; when the value is greater than the upper limit of the preset ambient temperature range, the fan speed per minute and the duty cycle of the fan are increased. The first computing element 15 determines whether the speed of the fan 11 is normal according to the above-mentioned updated standard.

Table 1 Normal Value Lookup Table 1 2 3 4 5 6 Default ambient temperature range 80～70 70～60 60～50 50～40 40～30 ＜35 Default system temperature range 95～90 90～80 80～70 70～60 60～50 ＜50 Fan revolutions per minute (RPM) 10,000 9,000 8,000 5,000 4,000 0 Provides fan duty cycle 100 90 75 50 40 0

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 computing element 15 can determine that the matching result is the first matching degree through the pre-stored lookup table. If 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), the first computing element 15 can control the alarm element 13 to output an alarm signal.

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 differs by 2.2 times from the fan speed corresponding to the duty cycle of 50% in the lookup table. At this time, the first computing element 15 can use the pre-stored lookup table to determine that the matching result is the 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 computing element 15 can stop the operation of the fan 11.

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 higher than the preset system temperature. At this time, the first computing element 15 can determine through the pre-stored lookup table that the comparison result is that the system temperature is greater than the upper limit of the preset system temperature range, then the first computing element 15 can stop the operation of the fan 11 and turn off the system switch element 12.

Assuming that the value of the temperature sensor sensing the ambient temperature is 43 degrees, the temperature sensed by the temperature sensor 14 is 95 degrees, the current speed of the fan 11 is 10,001RPM, and the duty cycle is 100%, the sensed ambient temperature is not higher than the upper limit of the preset ambient temperature range, then the first computing element 15 will reduce the fan speed per minute in the lookup table and the duty cycle provided to the fan, and 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 computing element 15 can determine that the matching result is the first matching degree through the pre-stored lookup table, and the comparison result is that the system temperature is not higher than the upper limit of the preset system temperature range, then the first computing element 15 can control the warning element 13 to output a warning signal.

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

Please refer to FIG. 4, which is a functional block diagram of a computing system according to another embodiment of the present invention. As shown in FIG. 4, the computing system 1' includes 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 wired 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 the fan 11, the system switch element 12, the alarm element 13, the temperature sensor 14, and the first computing element 15 included in the computing system 1 of FIG. 1, and are not described in detail here.

The second computing element 16 is used to execute a preset application. 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 not only execute the steps S11 to S15 of FIG. 2, but also execute the step of evaluating the degree of fan degradation.

Please refer to FIG. 5 , which is a flow chart of a computing system control method for evaluating the degree of fan degradation according to an embodiment of the present invention. As shown in FIG. 5 , 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 default 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 executed by the computing system 1 ' shown in FIG. 4 , and the following exemplary implementation of each step is described using the computing system 1 ' shown in FIG. 4 .

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 default application. 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 power supply voltages, the power value of the central processing unit, the power value of the panel, and the brightness value. Furthermore, the temperature sensor sensing the ambient temperature may be set at a position far away from the main cooling object so as to sense the real temperature of the environment without being affected by the temperature of the main cooling object.

In step S22, the first computing element 15 or the second computing element 16 uses the plurality of system parameters and the pre-trained model to obtain the degradation degree of the fan 11. Specifically, the first computing element 15 or the second computing element 16 obtains the degradation degree of the fan 11 by inputting the plurality of system parameters into the pre-trained model. Furthermore, the pre-trained model can be generated by using the multiple system parameter data under normal conditions and fault conditions to mark the probability of the fan 11 requiring maintenance at one or more time points (for example, one week later and two weeks later) according to the different situations corresponding to the data, and inputting the labeled data as training data into a neural network architecture such as a multi-layer sensor, convolutional neural network or recurrent neural network that can handle large amounts of data and complex nonlinear problems for training.

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

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 output 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.

In one embodiment, after the first computing element 15 obtains a plurality of system parameters when the computing system only executes the default application, the plurality of system parameters are input into the 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 the default application, the plurality of system parameters are input into the 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.

Through the above structure, the computing system and control method disclosed in this case can control the fan, system switch components and warning components 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 using a traditional over-current protection circuit to prevent the fan from failing due to excessive current, the computing system and control method disclosed in this case can replace the over-current protection circuit to provide the function of preventing the fan from failing due to excessive current, thereby saving the board area and reducing costs, and can solve the problem of abnormal operation of the fan itself that the over-current protection circuit cannot handle. In addition, by controlling the fan, system switch power or warning components according to the matching results and comparison results, the computing system and control method disclosed in this case can further utilize 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.

Although the present invention is disclosed as above with the aforementioned embodiments, it is not intended to limit the present invention. Any changes and modifications made within the spirit and scope of the present invention are within the scope of patent protection of the present invention. Please refer to the attached patent application for the scope of protection defined by the present invention.
