DETAILED DESCRIPTION

[0011] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0012] The fan status detection method of the present application can be applied to a fan status detection device or an electronic device. The fan status detection device can be deployed in an electronic device. The electronic device has a built-in fan that dissipates heat from the electronic device. The electronic device can be a device equipped with Bluetooth connectivity, communication capabilities, computing capabilities, and a display. Electronic devices can include, but are not limited to, smartphones, tablets, laptops, desktop computers, smart home appliances, wearable devices, in-vehicle computers, and virtual reality devices. Electronic devices can communicate with other electronic devices or servers via wired or wireless networks. The server can be a standalone physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), big data, and artificial intelligence platforms. The server can be used to provide services for applications running on the electronic device. The fan status detection method of the present application will be described below using an electronic device as an example.

[0013] See also Figure 1 , Figure 1 FIG. 1 is a flow chart showing a fan status detection method according to an embodiment of the present application. Figure 1 As shown, the fan status detection method includes steps S110 to S130.

[0014] Step S110: After the fan is turned on, the current duty cycle, current speed, and current temperature of the fan are obtained.

[0015] Duty cycle refers to the proportion of power-on time to the total time in a pulse cycle, that is, the ratio of the high level duration in the pulse signal to the entire cycle time.

[0016] The electronic device can read the fan status in real time. When the fan status changes from off to on, the fan turns on. After the fan turns on, the electronic device can obtain the fan's current duty cycle, current speed, and current temperature. The current fan temperature refers to the ambient temperature.

[0017] Step S120: If the current speed is greater than or equal to the speed threshold, obtain the calibrated speed corresponding to the current duty cycle as the target calibrated speed, and obtain the difference threshold corresponding to the current temperature as the target difference threshold, where different duty cycles correspond to different calibrated speeds, and different temperatures correspond to different difference thresholds.

[0018] The speed of the fan can reflect whether the fan is stuck or damaged and whether the air inlet and outlet of the fan are blocked. This application sets a speed threshold (for example, 1000 revolutions per minute), which is used to determine whether the fan is stuck or damaged. The electronic device can determine whether the current speed of the fan is less than the speed threshold. If the current speed of the fan is greater than or equal to the speed threshold, it can be determined that the fan is in a normal state and is not stuck or damaged, and the air inlet and outlet of the fan can be further detected to see if they are blocked. If the current speed of the fan is less than the speed threshold, it can be determined that the fan is stuck or damaged, and the user is reminded that the fan is suspected of being stuck or damaged or stuck, and the user is reminded to inspect the fan and turn off the fan to avoid the fan being stuck or damaged, which will cause the noise of the electronic device to increase, the heat dissipation to deteriorate, and the energy efficiency of the entire machine to deteriorate.

[0019] It is understandable that at the factory mold inspection station, the speed of the electronic device's fan at different duty cycles in the unblocked state can be tested. For example, the speed can be calibrated by obtaining the speed once every 5% duty cycle, thereby obtaining different calibrated speeds corresponding to different duty cycles, obtaining the corresponding relationship between the duty cycle and the calibrated speed, and then writing the corresponding relationship between the duty cycle and the calibrated speed into the storage area of ​​the electronic device. The storage area can be a permanent storage area, such as a fixed partition of the electronic device.

[0020] It is understandable that in the whole device, the speed of the fan when the air inlet and outlet are blocked will be higher than the speed when the air inlet and outlet are not blocked. The present application determines whether the fan inlet and outlet are blocked based on the deviation value of the fan speed. In addition, the speed of the fan will be affected by the ambient temperature. The higher the ambient temperature, the faster the fan speed. Therefore, the present application sets different difference thresholds according to different temperatures, and writes the correspondence between the temperature and the difference threshold into the storage area of ​​the electronic device, so that when detecting whether the fan inlet and outlet are blocked in step S130, the speed deviation value is corrected by temperature to avoid detection errors caused by the temperature affecting the fan speed. Among them, the storage area can be a permanent storage area, for example, a fixed partition of the electronic device.

[0021] When the current speed of the fan is greater than or equal to the speed threshold, the calibrated speed corresponding to the current duty cycle can be obtained as the target calibrated speed, and the difference threshold corresponding to the current temperature can be obtained as the target difference threshold, so that in step S130, whether the air inlet and outlet of the fan are in a blocked state can be detected based on these data.

[0022] Step S130: detecting whether the air inlet and outlet of the fan are in a blocked state according to the current speed, the target calibrated speed, and the target difference threshold.

[0023] In a complete device, the speed of a fan's air inlet and outlet is higher when blocked than when unblocked. This application determines whether the fan's air inlet and outlet are blocked based on the fan's speed deviation. The electronic device can determine the difference between the current speed and the target calibrated speed; if the difference is greater than a target difference threshold, the fan's air inlet and outlet are blocked; if the difference is less than or equal to the target difference threshold, the fan's air inlet and outlet are normal.

[0024] In some embodiments, after determining that a fan's air inlet and outlet are blocked, a user can be reminded to check the fan's air inlet and outlet status, thereby preventing the blockage from causing poor heat dissipation in the electronic device, increased noise, and unnecessary power consumption. This reminder may include, but is not limited to, pop-up window reminders and voice reminders.

[0025] Steps S110 to S130 have the following technical effects: different calibrated speeds are set for different duty cycles of the fan, and different difference thresholds are set for different temperatures of the fan. Based on the current speed of the fan, the calibrated speed corresponding to the current duty cycle of the fan, and the difference threshold corresponding to the current temperature of the fan, it is possible to accurately and in real time detect whether the air inlet and outlet of the fan are blocked and dust is accumulated, so that corresponding strategies can be made in time when the air inlet and outlet of the fan are blocked (for example, reminding the user to check the status of the fan flow channel and turn off the fan), thereby avoiding the increase in noise of electronic equipment, deterioration of heat dissipation, waste of power consumption, etc. caused by fan blockage, thereby improving user experience.

[0026] See also Figure 2 , Figure 2 FIG. 1 is a flow chart showing a fan status detection method according to another embodiment of the present application. Figure 2 As shown, the fan status detection method includes steps S210 to S2100.

[0027] Step S210: In response to the fan being turned from an off state to an on state, the number of times the fan's air inlet and outlet are blocked is assigned to zero.

[0028] The electronic device can read the status of the fan in real time. When the status of the fan changes from the off state to the on state, the fan is turned on. At this time, the number of blockages of the fan inlet and outlet can be set to zero.

[0029] Step S220: Obtain the current duty cycle, current speed, and current temperature of the fan.

[0030] Step S230: Determine whether the current rotation speed is less than the rotation speed threshold.

[0031] If the current rotation speed is less than the rotation speed threshold, the fan is determined to be stuck or damaged, and the user is reminded that the fan is suspected to be stuck or damaged and to turn off the fan (step S240).

[0032] If the current rotation speed is greater than or equal to the rotation speed threshold value, it is determined that the fan is in a normal state, at this time, the target calibration rotation speed corresponding to the current duty ratio is obtained as the target calibration rotation speed, and the difference threshold value corresponding to the current temperature is obtained as the target difference threshold value (step S250), so as to further determine whether the inlet and outlet of the fan are blocked according to these data.

[0033] Step S240: determining that the fan is stuck or damaged, reminding the user that the fan is suspected to be stuck or damaged, and reminding the user to turn off the fan.

[0034] In the case of fan stuck or damaged, the user is reminded that the fan is suspected to be stuck or damaged, and the user is reminded to turn off the fan, so as to timely remind the user to repair the fan and avoid the fan being stuck or damaged to bring additional impact to the electronic equipment. The reminding mode can include but is not limited to pop-up window reminding and voice reminding.

[0035] Step S250: obtaining the target calibration rotation speed corresponding to the current duty ratio as the target calibration rotation speed, and obtaining the difference threshold value corresponding to the current temperature as the target difference threshold value.

[0036] Step S260: detecting whether the inlet and outlet of the fan are in a blocked state according to the current rotation speed, the target calibration rotation speed and the target difference threshold value.

[0037] In the whole machine equipment, the rotation speed of the fan when the inlet and outlet are blocked is higher than that when the inlet and outlet are not blocked. The application determines whether the inlet and outlet of the fan are blocked according to the deviation value of the rotation speed of the fan. The electronic equipment can determine the difference between the current rotation speed and the target calibration rotation speed; if the difference is greater than the target difference threshold value, it is determined that the inlet and outlet of the fan are in a blocked state; if the difference is less than or equal to the target difference threshold value, it is determined that the inlet and outlet of the fan are in a normal state.

[0038] If the inlet and outlet of the fan are in a normal state, the blocked hole number is cleared (step S270).

[0039] If the inlet and outlet of the fan are in a blocked state, the blocked hole number is increased by 1 (step S280).

[0040] Step S270: clearing the blocked hole number.

[0041] In some embodiments, after the blocked hole number is cleared, the next fan state detection can be directly entered into step S220, so as to realize uninterrupted continuous detection of the fan state and realize the effect of long-term monitoring of the fan state.

[0042] In other embodiments, as Figure 2As shown, after the number of hole blockages is cleared, step S2100 can be executed to perform a timing operation, and after a preset time period, step S220 can be entered to perform the next fan status detection, thereby realizing intermittent continuous detection of the fan status, achieving the effect of long-term monitoring of the fan status while saving a certain amount of power consumption.

[0043] Step S280: Add 1 to the number of hole blocking times.

[0044] After the number of blockages is increased by 1, it is possible to detect whether the fan's air inlet and outlet are blocked for a long time based on the number of blockages and the blockage threshold (step S290), so as to formulate corresponding strategies for the two situations of short-term and long-term blockage of the fan's air inlet and outlet, thereby avoiding the increase in noise of electronic equipment, deterioration of heat dissipation, waste of power consumption, etc. caused by fan blockage, and improving user experience.

[0045] Step S290: Detecting whether the air inlet and outlet of the fan are blocked for a long time based on the number of blockages and the blockage threshold.

[0046] The blockage threshold is used to determine whether the fan's air inlet and outlet are chronically blocked. The electronic device can determine whether the number of blockages is less than the blockage threshold. If the number of blockages is less than the blockage threshold, the fan's air inlet and outlet are temporarily blocked. If the number of blockages is greater than or equal to the blockage threshold, the fan's air inlet and outlet are chronically blocked. The blockage threshold (for example, 150 times) can be pre-calibrated and stored in a permanent storage area of ​​the electronic device.

[0047] In some embodiments, upon determining that a fan's air inlet or outlet is temporarily blocked, the user can be alerted to the blockage and asked to check the fan's air inlet or outlet. This can help prevent noise buildup, poor heat dissipation, and wasted power consumption, thereby improving user experience. This alert can include, but is not limited to, pop-up window notifications and voice notifications.

[0048] In other embodiments, to avoid frequent reminders affecting the user experience, the present application sets a first value and a second value for controlling the frequency of reminding the user that the fan's air inlet and outlet are blocked, wherein the first value (e.g., 1) is less than the second value (e.g., 101), and the second value is less than a threshold value for the number of times the fan's air inlet and outlet is blocked (e.g., 150). After determining that the fan's air inlet and outlet are blocked for a short period of time, it is possible to detect whether the number of times the fan's air inlet and outlet is blocked is the first value or the second value; if the number of times the fan's air inlet and outlet is blocked is the first value or the second value, the user is reminded that the fan's air inlet and outlet are blocked; if the number of times the fan's air inlet and outlet is blocked is not the first value or the second value, the user is not reminded that the fan's air inlet and outlet are blocked, thereby controlling the frequency of reminding the user that the fan's air inlet and outlet are blocked, and avoiding frequent reminders that disturb the user and affect the user experience.

[0049] In some embodiments, after reminding the user that the fan's air inlet and outlet are in a blocked state, or after determining that the number of blockages is not the first value and the second value, the process can directly enter step S220 for the next fan status detection, thereby achieving uninterrupted and continuous detection of the fan status and realizing the effect of long-term monitoring of the fan status.

[0050] In other embodiments, after reminding the user that the fan's air inlet and outlet are in a blocked state, or after determining that the number of blockages is not the first value and the second value, step S2100 can be executed first to perform a timing operation, and after a preset time has passed, step S220 can be entered to perform the next fan status detection, thereby realizing intermittent continuous detection of the fan status, achieving the effect of long-term monitoring of the fan status while saving a certain amount of power consumption.

[0051] In some embodiments, after determining that the fan's air inlet and outlet are blocked for a long time, the user can be reminded that the fan's air inlet and outlet are blocked for a long time and the user can be reminded to turn off the fan after checking the fan's air inlet and outlet, thereby avoiding increased noise in electronic equipment, worsened heat dissipation, and waste of power consumption caused by fan blockage, thereby improving user experience.

[0052] In other embodiments, in order to avoid frequent reminders affecting the user experience, the present application sets a third value for reminding the user when the fan's air inlet and outlet are blocked for a long time, which may cause the fan to get stuck or damaged. The third value (for example, 201) is greater than the blockage threshold (for example, 150). After determining that the fan's air inlet and outlet are blocked for a long time, it is possible to detect whether the number of blockages is the third value; if the number of blockages is the third value, the user is reminded that the fan's air inlet and outlet are blocked for a long time and the user is reminded to turn off the fan after checking the fan's air inlet and outlet; if the number of blockages is not the third value, the user is not reminded that the fan's air inlet and outlet are blocked for a long time, thereby reminding the user when the fan's air inlet and outlet are blocked for a long time, which may cause the fan to get stuck or damaged, avoiding frequent reminders that affect the user experience and avoiding the deterioration of the device's heat dissipation and noise caused by the fan's air inlet and outlet being blocked for a long time.

[0053] In some embodiments, after determining that the number of hole blocking times is not the third value, the process can directly proceed to step S220 to perform the next fan status detection, thereby achieving uninterrupted and continuous detection of the fan status and achieving the effect of long-term monitoring of the fan status.

[0054] In other embodiments, after determining that the number of hole blockages is not the third value, step S2100 can be executed first to perform a timing operation, and then step S220 can be entered to perform the next fan status detection after a preset time period, thereby realizing intermittent continuous detection of the fan status, achieving the effect of long-term monitoring of the fan status while saving a certain amount of power consumption.

[0055] Step S2100: Start timing and determine whether the timing duration reaches a preset duration.

[0056] The preset duration (for example, 3 seconds) is used to control the frequency of detecting the fan status. The shorter the preset duration, the higher the real-time performance of detecting the fan status. Whenever step S2100 is started, the timer is started from zero and the timing duration is obtained to determine whether the timing duration has reached the preset duration. When the timing duration reaches the preset duration, step S220 is entered for the next fan status detection. When the timing duration has not reached the preset duration, it is continued to determine whether the timing duration has reached the preset duration. Based on step S2100, intermittent and continuous detection of the fan status can be achieved, which can save a certain amount of power consumption while achieving long-term monitoring of the fan status.

[0057] Compared with steps S110 to S130, steps S210 to S2100 also have the following additional technical effects: they can accurately and continuously identify various fan states, such as the fan being in normal state, stuck or damaged state, the fan's air inlet and outlet being blocked for a short period of time, and the fan being blocked for a long period of time, so as to formulate different strategies for different fan states, and promptly remind the user when the fan is stuck or damaged or the hole is blocked, thereby avoiding the increase in noise of electronic equipment, deterioration of heat dissipation, waste of power consumption, etc. caused by the fan being stuck or damaged or the hole being blocked, thereby improving the user experience.

[0058] See also Figure 3 , Figure 3 FIG. 1 is a flow chart showing a fan status detection method according to another embodiment of the present application. Figure 3 As shown, the fan status detection method may include steps S310 to S3140.

[0059] Step S310: In response to the fan being turned from an off state to an on state, the number of times the fan's air inlet and outlet are blocked is assigned to zero.

[0060] Step S320: Obtain the current duty cycle, current speed, and current temperature of the fan.

[0061] Step S330: Determine whether the current rotation speed is less than the rotation speed threshold.

[0062] If the current rotation speed is less than the rotation speed threshold, it is determined that the fan is stuck or damaged, and the user is reminded that the fan is suspected to be stuck or damaged and to turn off the fan (step S340).

[0063] If the current speed is greater than or equal to the speed threshold, a calibrated speed corresponding to the current duty cycle is obtained as a target calibrated speed, and a difference threshold corresponding to the current temperature is obtained as a target difference threshold (step S350 ).

[0064] Step S340: Determine whether the fan is stuck or damaged, and remind the user that the fan is suspected to be stuck or damaged and remind the user to turn off the fan.

[0065] Step S350: obtaining a calibrated speed corresponding to the current duty cycle as a target calibrated speed, and obtaining a difference threshold corresponding to the current temperature as a target difference threshold.

[0066] Step S360: Detect whether the air inlet and outlet of the fan are in a blocked state according to the current speed, the target calibrated speed, and the target difference threshold.

[0067] If the air inlet and outlet of the fan are in normal state, the number of hole blockages is reset to zero (step S370 ).

[0068] If the air inlet and outlet of the fan are in a blocked state, the number of blocked times is increased by 1 (step S380 ).

[0069] Step S370: clear the number of hole blocking times to zero.

[0070] After the number of hole blocking times is reset to zero, the process proceeds to step S3140 to perform a timing operation, and after a preset time has elapsed, the process proceeds to step S320 to perform the next fan status detection.

[0071] Step S380: Add 1 to the number of hole blocking times.

[0072] Step S390: Determine whether the number of hole blocking times is less than a hole blocking times threshold.

[0073] If the hole blocking times are less than the hole blocking times threshold, it is determined whether the hole blocking times are the first value or the second value (step S3100 ).

[0074] If the hole blocking times are greater than or equal to the hole blocking times threshold, it is determined whether the hole blocking times are a third value (step S3120 ).

[0075] Step S3100: Determine whether the number of hole blocking times is the first value or the second value.

[0076] If the number of blockages is the first value or the second value, the user is reminded that the air inlet and outlet of the fan are in a blocked state (step S3110 ).

[0077] If the number of hole blocking times is not the first value or the second value, the process first proceeds to step S3140 to perform a timing operation, and then proceeds to step S320 to perform the next fan status detection after a preset time has passed.

[0078] Step S3110: Remind the user that the air inlet and outlet of the fan are blocked.

[0079] After reminding the user that the fan's air inlet and outlet are in a blocked state, the process first enters step S3140 to perform a timing operation, and then enters step S320 to perform the next fan status detection after a preset time has passed.

[0080] Step S3120: Determine whether the number of hole blocking times is a third value.

[0081] If the number of blockages is the third value, the user is reminded that the air inlet and outlet of the fan are blocked for a long time and the user is reminded to turn off the fan after checking the air inlet and outlet of the fan (step S3130).

[0082] If the number of hole blocking times is not the third value, the process proceeds to step S3140 to perform a timing operation, and after a preset time period, the process proceeds to step S320 to perform the next fan status detection.

[0083] Step S3130: Remind the user that the air inlet and outlet of the fan are blocked for a long time and remind the user to turn off the fan after checking the air inlet and outlet of the fan.

[0084] Step S3140: Start timing and determine whether the timing duration reaches a preset duration.

[0085] Whenever step S3140 is executed, the timer is started, starts counting from zero, obtains the time duration, and determines whether the time duration has reached the preset time duration. When the time duration reaches the preset time duration, the process proceeds to step S320 for the next fan status check. If the time duration has not reached the preset time duration, the process continues to determine whether the time duration has reached the preset time duration. Based on step S3140, intermittent and continuous fan status detection can be achieved, thus enabling long-term monitoring of the fan status while saving a certain amount of power consumption.

[0086] Compared with steps S110 to S130, steps S310 to S3140 also have the following additional technical effects: they can accurately and continuously identify various fan states, such as the fan being in normal state, stuck or damaged state, the fan's air inlet and outlet being blocked for a short period of time, and the fan being blocked for a long period of time, so as to formulate different strategies for different fan states, and promptly remind the user when the fan is stuck or damaged or the hole is blocked, thereby avoiding the increase in noise of electronic equipment, deterioration of heat dissipation, waste of power consumption, etc. caused by the fan being stuck or damaged or the hole being blocked, thereby improving the user experience.

[0087] See also Figure 4 , Figure 4 FIG. 1 shows a schematic diagram of the structure of a fan status detection device provided by an embodiment of the present application. Figure 4As shown, the fan status detection device 100 includes: a real-time data acquisition module 110, a calibration data acquisition module 120, and a fan status detection module 130. The real-time data acquisition module 110 is used to: after the fan is turned on, obtain the current duty cycle, current speed, and current temperature of the fan. The calibration data acquisition module 120 is used to: if the current speed is greater than or equal to the speed threshold, obtain the calibrated speed corresponding to the current duty cycle as the target calibrated speed, and obtain the difference threshold corresponding to the current temperature as the target difference threshold, wherein different duty cycles correspond to different calibrated speeds, and different temperatures correspond to different difference thresholds. The fan status detection module 130 is used to: detect whether the air inlet and outlet of the fan are in a blocked state based on the current speed, the target calibrated speed, and the target difference threshold.

[0088] In some embodiments, the fan status detection module 130 is also used to: determine the difference between the current speed and the target calibrated speed; if the difference is greater than the target difference threshold, determine that the fan's air inlet and outlet are in a blocked state; if the difference is less than or equal to the target difference threshold, determine that the fan's air inlet and outlet are in a normal state.

[0089] In some embodiments, the fan status detection module 130 is also used to: before obtaining the current duty cycle, current speed, and current temperature of the fan, in response to the fan changing from an off state to an on state, assign the number of blockages of the fan inlet and outlet to zero.
