Description

Technical Field

[0001] The present application relates to the field of electronic equipment maintenance, and specifically to a dust accumulation detection method, device, storage medium and electronic equipment. Background Art

[0002] The heat dissipation of the internal devices and components of electronic equipment is generally achieved by using fans to create a circulating airflow, transferring heat from the inside of the device to the outside. The amount of circulating air directly affects the heat dissipation performance of the device, and the ventilation environment has a significant impact on the circulating air volume. Therefore, a good ventilation environment is necessary to ensure the heat dissipation of the device. However, existing electronic devices, such as display devices, have a variety of application scenarios, such as classrooms, conference rooms, outdoor areas, shopping malls, and other areas. Long-term use can easily lead to dust accumulation on air ducts, air outlets, and fan blades. The dust then absorbs moisture from the air and attracts and gathers more dust, gradually clogging the air outlets and air ducts. Because dust absorbs moisture, it provides an environment conducive to bacterial growth, polluting the room air.

[0003] When the fan is running, the air inlet side is under negative pressure, which is pressurized by the fan blades and discharged from the air outlet side. Therefore, dust accumulation on the equipment is mainly caused by natural dust falling and dust adsorption in the negative pressure area when the fan is running. The existing technical solutions to the problem of dust accumulation in the air duct are that the better solution is the air duct / fan layout, which makes the main air duct in a positive pressure state, so that the dust is concentrated on the air inlet side and accumulates. The air inlet side is equipped with a dustproof net or adsorption material, such as a HEPA filter; for natural dust falling, the main method is to use louver air vents or avoid opening air vents in the vertical direction to reduce the natural dust from entering the equipment. In addition, electrostatic adsorption components can be arranged on the air inlet side to reduce the use of filter consumables; a common method is to clean or replace them regularly. Since display devices are generally large in size and weight, it is inconvenient to clean or replace consumables, and regular cleaning or replacement is somewhat blind and does not take into account the actual usage and environmental impact. Therefore, the detection method of the degree of dust accumulation is crucial.

[0004] The accumulation of dust will block the air outlet, resulting in reduced air volume and increased device temperature rise. Therefore, existing technical solutions and patents generally use one of the following methods as the basis for judgment: detecting the wind speed at the air outlet, determining the difference between the temperature in the cavity or between the device and the ambient temperature (i.e., temperature rise), and setting a certain threshold range to avoid misjudgment. This technical solution is relatively simple, but because it is a single judgment condition, it is easily interfered with by the external environment and may lead to misjudgment. The deployment of more sensors will also increase the cost and complexity of the product. Summary of the Invention

[0005] The purpose of the present invention is to provide a dust accumulation detection method, device, storage medium and electronic equipment to improve the problems of the existing technical solutions such as single dust accumulation detection judgment, low accuracy and high detection cost.

[0008] Furthermore, when the temperature fluctuation of the device temperature is greater than the fluctuation threshold, if the operating main frequency of the device is lower than the main frequency threshold and / or the operating power of the device is lower than the power threshold, a dust accumulation warning is recorded.

[0009] Furthermore, when the temperature fluctuation of the device temperature is less than the fluctuation threshold, if the operating main frequency of the device is lower than the set main frequency, a dust accumulation warning is recorded.

[0010] Furthermore, when the temperature fluctuation of the device temperature is less than the fluctuation threshold, if the temperature difference between the device temperature of the preset device and the set device temperature is greater than the second temperature difference threshold and the device is not in an overclocked state, it is determined whether the difference between the processor temperature of the device and the device temperature is greater than the third temperature difference threshold, and if it is greater, a dust accumulation warning is recorded.

[0015] and / or

[0016] When the number of consecutively recorded dust accumulation warnings exceeds a second preset number, a dust accumulation cleaning prompt message is generated.

[0017] Furthermore, the temperature fluctuation is the ratio of the arithmetic mean of the absolute values ​​of the temperature differences of N consecutive preset cycles to the temperature value of the current cycle, and the heating rate is the ratio of the temperature difference between two preset cycles to the preset cycle.

[0021] The recording module is configured to record a dust accumulation warning when the fan is not faulty and the fan speed is greater than the speed threshold for a period of time exceeding a preset time.

[0022] In a third aspect, an embodiment of the present invention provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed on a computer, the computer executes the method of the first aspect.

[0023] In a fourth aspect, an embodiment of the present invention provides an electronic device comprising a memory and a processor, wherein the processor executes the method of the first aspect by calling a computer program stored in the memory.

[0035] Figure 1 This is a block diagram of the architecture of an electronic device 10 according to some embodiments of the present application. The electronic device 10 may be a display device, such as a display screen or monitor installed in a classroom, conference room, outdoor area, shopping mall, or other area. Over long-term use, the air duct of the electronic device 10 is prone to dust accumulation, leading to blockage of the air vents or ducts. The present embodiments provide a dust accumulation detection method for detecting dust accumulation in the electronic device 10.

[0036] In some embodiments, the electronic device 10 may include a dust accumulation detection device 11, a memory 12 and a processor 13. The memory 12 and the processor 13 are electrically connected to each other directly or indirectly to realize data transmission or interaction.

[0037] The memory 12 may be, but is not limited to, a random access memory (RAM), a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), etc. The memory 12 is used to store programs, and the processor 13 executes the programs after receiving an execution instruction.

It can implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of the present invention. The general-purpose processor may be a microprocessor or any conventional processor.

[0039] I understand. Figure 1 The structure shown is for illustration only. The electronic device 10 may also include Figure 1 More or fewer components than shown, or with Figure 1 Different configurations shown. Figure 1 Each component shown in the figure can be implemented by hardware, software or a combination thereof.

[0040] Figure 2 and Figure 3 This is a flow chart of a dust accumulation detection method according to some embodiments of the present application, which is applied to Figure 1 The electronic device 10 may specifically include the following steps S101 to S112. Based on the following steps S101 to S112, some optional embodiments will be described. These embodiments should be understood as examples and should not be understood as essential technical features for implementing this solution.

[0041] Step S101 , obtaining the ambient temperature of the device, the device temperature of a preset device of the device, and the fan speed of the device.

[0042] The ambient temperature of the device is the temperature of the environment in which the electronic device 10 is located. The ambient temperature can be directly sensed by a temperature sensor provided in the electronic device 10, or it can be a temperature sensed by other devices received by the electronic device 10. This embodiment does not limit this. The preset components of the device are selected based on actual conditions, such as key components such as processors and hard disks that have a faster temperature rise. The device temperature can be sensed by a temperature sensor provided in the preset component. The fan of the device is a fan for dissipating heat for the device, and its speed can reflect the temperature inside the device. For example, the higher the fan speed, the higher the temperature inside the device.

[0043] Step S102, determine whether the temperature fluctuation of the device temperature is greater than the fluctuation threshold. When it is greater than the fluctuation threshold, execute steps S103A, S103B, S103C, and S103D. When it is less than the fluctuation threshold, execute steps S107A and A107B.

[0044] In this embodiment, temperature fluctuations indicate the degree of temperature change of a preset component. Generally speaking, when electronic device 10 is first powered on, the temperature of the preset component rises from low to high, and the temperature fluctuation is large during this stage. When the device operation stabilizes, the temperature is maintained within a certain range, and the device temperature fluctuation is small. In this embodiment, dust accumulation detection is performed in two stages: the unstable temperature stage and the stable temperature stage. Steps S103A, S103B, S103C, and S103D are steps for detecting and determining dust accumulation during the unstable temperature stage, while steps S107A and S107B are steps for detecting and determining dust accumulation during the stable temperature stage.

[0045] For the determination of the size of temperature fluctuation, in the method provided in the embodiment of the present invention, the temperature fluctuation is the ratio of the arithmetic mean of the absolute value of the temperature difference of N consecutive preset cycles to the temperature value of the current cycle. It should be noted that in the embodiment of the present invention, the memory obtains the temperature of the preset device once every preset cycle, such as the temperature of the CPU. Each time the temperature is recorded, the temperature difference between the device temperature of the current cycle and the device temperature of the previous cycle is calculated. Every time N cycles are recorded, the arithmetic mean of the absolute value of the temperature difference of the previous N cycles is calculated, and then the ratio of the arithmetic mean to the temperature value of the current cycle is used as the temperature fluctuation. For example, when the electronic device 10 is powered on, the CPU temperature is recorded every Δt seconds, which are recorded as T1, T2, T3...T n . Calculate ΔT1=T2-T1, ΔT2=T3-T2...ΔT n =T n -T n-1 When recording to the Nth time, after each calculation, the arithmetic average of the absolute values ​​of the previous N times is obtained:

[0046] Temperature fluctuation δ=(|ΔT n |+|ΔT n-1 |+|ΔT n-2 |+|ΔT n-3 |+|ΔT n-4 |) / 5T n The value of N can be set according to the actual situation of the electronic device 10, for example, it can be set to 5.

[0047] Step S103A, determining whether the temperature difference between the ambient temperature and the device temperature is greater than a first temperature difference threshold; if so, executing step S104.

[0048] The temperature difference between the ambient temperature and the device temperature can reflect the heat dissipation of the device. Generally speaking, if the air duct and air outlet are unobstructed, there is no dust accumulation or little dust accumulation, and the device heat dissipation is normal, the device temperature will gradually decrease and approach the ambient temperature. If the device temperature exceeds the ambient temperature by more than a certain degree, for example, exceeding the first temperature difference threshold, the heat dissipation of the device may be abnormal, and there is a possibility of more dust accumulation.

[0049] Step S103B, determining whether the heating rate of the device temperature is greater than a speed threshold, if so, executing step S104.

[0050] When the heat dissipation of the device is normal, the temperature rise rate of the device is often slow, and the temperature rise rate is not very fast. However, if there is dust accumulation in the heat dissipation channels such as the air duct or air outlet of the electronic device 10, it will affect the heat dissipation of the device and cause the temperature rise rate of the device to rise rapidly. In this embodiment, when the temperature rise rate of the device is greater than the speed threshold, there is a possibility of dust accumulation. The temperature rise rate is the ratio of the temperature difference between two preset cycles to the preset cycle. Based on the above example of temperature fluctuation, the temperature rise rate μ = ΔT n / Δt.

[0051] Step S104: Determine whether the fan is faulty. If the fan is not faulty, proceed to step S105.

[0052] As shown in steps S103A and S103B above, when the temperature difference between the ambient temperature and the device temperature is too large or the device temperature rises quickly, there is a possibility of excessive dust accumulation. Before reaching this conclusion, it is necessary to rule out other situations that may affect the heat dissipation of the device, such as fan failure. If the fan is not faulty, then check for other influencing factors.

[0053] Step S105 , determining whether the fan speed is greater than a speed threshold. If so, executing step S106 .

[0054] If the fan is not faulty and can operate normally, continue to determine the fan speed. It is easy to understand that the higher the device temperature, the faster the fan speed will be in order to cool it down quickly. When the fan speed is high, if the device temperature still cannot drop quickly, it can be considered that the air duct or air outlet is blocked by dust.

[0055] Step S106 , determining whether the duration during which the fan speed is greater than the speed threshold is greater than a preset duration. If so, executing step S110 .

[0056] Step S110: Record dust accumulation warning.

[0057] If the fan speed is high and the time it maintains the high speed exceeds the preset time, it can be inferred that the fan's heat dissipation is hindered and there is a high possibility of dust accumulation in the air duct or air outlet, and a dust accumulation warning is issued.

[0058] Through the above steps, the embodiment of the present invention analyzes the heat dissipation of the device by using factors such as the device temperature, ambient temperature, and fan speed during the unstable stage of device temperature rise, making the determination of dust accumulation more accurate. In other embodiments, other operating parameters of the electronic device 10 can also be used to provide an early warning of dust accumulation, for example:

[0059] Step S103C: determine whether the operating main frequency of the device is lower than the main frequency threshold. If so, execute step S110.

[0060] Step S103D: determine whether the operating power of the device is lower than the power threshold. If so, execute step S110.

[0061] If the operating main frequency and / or operating power of the electronic device 10 is lower than the set threshold range, it can be determined that the electronic device 10 has protective frequency reduction, the heat dissipation efficiency has decreased, and a dust accumulation warning is recorded.

[0062] The following describes the dust accumulation detection process when the device temperature enters the stable stage, that is, when the temperature fluctuation of the device temperature is less than the fluctuation threshold. Please refer to Figure 4 , comprising the following steps:

[0063] Step S107A: Determine whether the temperature difference between the preset device temperature and the set device temperature is greater than a second temperature difference threshold. If the temperature difference is greater than the second temperature difference threshold, execute step S108.

[0064] The device temperature is the real-time temperature of the device, and the set device temperature is the theoretical temperature of the device in its current operating state. This theoretical temperature is obtained through extensive experimentation and stored in a database for easy access when needed. If the device temperature differs significantly from the set device temperature, for example, exceeding a second temperature difference threshold, this indicates a possible heat dissipation issue with the device.

[0065] Step S108: Determine whether the device is in an overclocked state. If not, proceed to step S109.

[0066] Step S109 , determining whether the difference between the processor temperature and the device temperature of the device is greater than a third temperature difference threshold.

[0067] If the device is in the temperature stabilization stage and the difference between its temperature and the set device temperature is too large, possible situations include: there is a problem with the device heat dissipation and the device is in an overclocked state. If the device is not in an overclocked state, and compared with the processor of the electronic device 10, the temperature difference between its temperature and the processor is also too large, for example, exceeding the third temperature difference threshold, then the electronic device 10 is more likely to have dust accumulation resulting in poor heat dissipation, and a dust accumulation warning is recorded.

[0068] When the device is in the temperature stabilization stage, dust accumulation detection can also be judged by the device's operating frequency, for example:

[0069] Step S107B, determining whether the operating main frequency of the device is lower than the set main frequency, if it is lower than the set main frequency, executing step S110.

[0070] When the device is in the temperature stabilization stage, if the operating main frequency of the device is lower than the set main frequency, it can be determined that the electronic device 10 has protective frequency reduction, the heat dissipation efficiency has decreased, and a dust accumulation warning is recorded.

[0071] It should be noted that in the above steps, the specific values ​​of the first temperature difference threshold, the second temperature difference threshold, the third temperature difference threshold, the speed threshold, the rotation speed threshold, the preset duration, the fluctuation threshold, the main frequency threshold, the power threshold, the set main frequency, etc. mentioned are not limited in the embodiments of the present invention, and any possible numerical range falls within the scope covered by the embodiments of the present invention.

[0072] After the dust accumulation warning is issued, the embodiment of the present invention may further include the following steps:

[0073] Step S111, determining whether the number of dust accumulation warnings exceeds a preset number, and if so, executing step S112.

[0074] Step S112: Generate dust cleaning prompt information.

[0075] When the dust accumulation warning reaches a preset number of times, it indicates that the dust accumulation in the electronic device 10 is serious and dust cleaning is required. As an embodiment, step S111 may include:

[0076] If the number of dust accumulation warnings during a single startup exceeds a first preset number, a dust cleaning reminder message is generated. The first preset number can be set to 10. If the number of consecutive dust accumulation warnings exceeds a second preset number, a dust cleaning reminder message is generated. The second preset number can be set to 50.

[0077] To sum up, the dust accumulation detection method provided in the embodiment of the present invention divides the device temperature change into two stages, stable and unstable, through rigorous judgment logic, through parameters such as the ambient temperature of the device, the device temperature of the preset device of the device, and the fan speed of the device. The dust accumulation situation of the device is detected according to the corresponding judgment method at different temperature stages. The judgment method is diversified and the accuracy is higher than that of the existing technology.

[0078] Please refer to Figure 4 , is a schematic diagram of the structure of a dust accumulation detection device 11 provided in an embodiment of the present invention. The dust accumulation detection device 11 can be used to perform the dust accumulation detection method provided in an embodiment of the present invention, wherein the dust accumulation detection device 11 includes:

[0079] An acquisition module 111 is configured to acquire an ambient temperature of the device, a device temperature of a preset device of the device, and a fan speed of the device;

[0080] The judgment module 112 is configured to judge whether the fan has failed when the temperature fluctuation of the device temperature is greater than the fluctuation threshold, if the temperature difference between the ambient temperature and the device temperature is greater than the first temperature difference threshold, or if the heating rate of the device temperature is greater than the speed threshold;

[0081] The recording module 113 is configured to record a dust accumulation warning when the fan is not faulty and the fan speed is greater than the speed threshold for a period exceeding a preset time.

[0082] The acquisition module 111 may be used to execute step S101 , the determination module 112 may be used to execute steps S102 to S109 , and the recording module 113 may be used to execute step S110 .

[0083] Since the dust accumulation detection method provided by the embodiment of the present invention has been introduced in detail in the above embodiment, and the principle of the dust accumulation detection device 11 is the same as that of the method, the execution principle of each module of the dust accumulation detection device 11 will not be repeated here.
