Abstract
Description
Technical Field
[0001] This application relates to the field of pipeline dust removal technology, such as a pipeline dust removal method, a pipeline dust removal device, and an intelligent air conditioner based on wind-driven vibration. Background Technology
[0002] Currently, North American countries such as the United States and Canada use ducted split air conditioners for indoor cooling or heating. A ducted split air conditioner consists of an outdoor unit, an indoor unit, and connecting pipes. The indoor unit generates cold / hot air in cooling / heating mode. This air first enters the main supply air duct and then is distributed to various branch supply air ducts. Finally, it enters each room through the air inlet at the end of each branch supply air duct. Simultaneously, each room is equipped with a return air vent, and a corresponding return air duct branch is installed at the return air vent. The air in the room flows from the return air duct branch back to the main return air duct and then enters the indoor unit.
[0003] After prolonged use, dust accumulates in the ducts of an air conditioner. In this case, a vibration device can be installed in the air conditioner ducts. The vibration device can drive the ducts and dust to vibrate, causing the dust to be peeled off the ducts and achieving automatic dust removal.
[0004] In the process of implementing the embodiments of this application, at least the following problems were found in the related technology:
[0005] Existing technology uses electric vibration devices to drive pipe vibration to achieve pipe dust removal. When there are many pipes or a long individual pipe, a large number of vibration devices need to be installed, which can easily generate large instantaneous power, which is not conducive to energy saving and electrical safety.
[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention
[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.
[0008] This application provides a method, device, and intelligent air conditioner for dust removal of pipelines based on wind-driven vibration, in order to reduce the energy consumption required for the vibration dust removal process and make the vibration dust removal technology easy to apply to scenarios with a large number of pipelines.
[0009] In some embodiments, a wind-driven vibration device is installed inside the duct to be dusted, the wind-driven vibration device is in working condition, and the duct is equipped with a corresponding fan that can drive the airflow inside the duct; the duct dust removal method based on wind-driven vibration includes:
[0010] The system obtains the first fan speed and the first fan current at the start of the current control cycle, and the second fan speed and the second fan current at the start of the previous control cycle; wherein, the first fan speed is the fan speed at the end of the previous control cycle, and the first fan current is the fan current at the end of the previous control cycle.
[0011] The historical dust removal volume in the previous control cycle is determined based on the first fan speed, the first fan current, the second fan speed, and the second fan current.
[0012] The speed or current of the third fan in the current control cycle is determined based on the historical dust removal volume; wherein, the speed of the third fan and the historical dust removal volume are positively correlated, or the current of the third fan and the historical dust removal volume are positively correlated.
[0013] The fan is controlled by the speed or current of the third fan to adjust the air velocity in the duct, thereby adjusting the vibration effect of the wind-driven vibration device.
[0014] The dust removal method for pipelines based on wind-driven vibration provided in this application can achieve the following technical effects:
[0015] The second fan speed and the second fan current are the fan states at the beginning of the previous control cycle, while the first fan speed and the first fan current are the fan states at the end of the previous control cycle.
[0016] The first fan speed and the first fan current can represent the amount of dust in the pipe at the beginning of the previous control cycle; the second fan speed and the second fan current can represent the amount of dust in the pipe at the end of the previous control cycle.
[0017] Thus, the historical dust removal volume determined based on the first fan speed, the first fan current, the second fan speed, and the second fan current can represent the dust removal result in the previous control cycle, that is, the result achieved by the following process: the wind speed generated in the pipeline by the second fan speed or the second fan current causes the wind-driven vibration device to achieve a vibration effect, which causes the pipeline to vibrate, and the dust on the inner wall of the pipeline is peeled off and blown away by the wind.
[0018] In other words, the second fan speed or the second fan current can also indicate the vibration effect of the wind-driven vibration device and the resulting dust removal effect. Generally speaking, the higher the second fan speed or the second fan current, the higher the air velocity in the pipeline, the greater the vibration amplitude of the wind-driven vibration device, and the better its dust removal effect.
[0019] In the current control loop, the determined third fan speed or third fan current has a positive correlation with the total amount of dust. If this third fan speed or third fan current is used to control the fan, the following situation will occur:
[0020] If the historical dust volume is high, and the current total dust volume is also high, and assuming that the dust removal process in the current control loop will not change the total dust volume from "high" to "low," then the current control loop will use a higher third fan speed or current. This higher third fan speed or current will result in a higher air velocity in the duct, leading to a stronger vibration effect from the wind-driven vibration device. The higher air velocity and stronger vibration effect result in better dust removal from the duct. Consequently, the historical dust volume determined in the next control loop (the control loop following the current one) will be even higher (using the historical dust volume determined in the current control loop as a comparison benchmark). The third fan speed or current determined in the next control loop will be even higher, further increasing the dust removal effect. This cycle repeats, which helps to reduce the total dust content relatively quickly.
[0021] If the historical dust volume is large, but the current total dust volume is small, the current control cycle will use a lower third fan speed or current. This lower speed or current will result in lower air velocity in the duct, leading to weaker vibration from the wind-driven vibration device. The lower air velocity and weaker vibration further reduce dust removal efficiency. Consequently, the historical dust volume determined in the next control cycle will be even smaller, resulting in a lower third fan speed or current and further weakened dust removal. This cycle repeats, helping to terminate the dust removal process more quickly and reducing instances of particularly poor or ineffective dust removal.
[0022] If the historical dust volume is relatively low, and the current total dust volume is also relatively low, then referring to the above analysis of "the historical dust volume is relatively high, and the current total dust volume is relatively low", the dust removal process will be terminated more quickly, in order to reduce dust removal processes that are particularly poor or even ineffective.
[0023] If the historical dust volume is relatively low, but the total dust volume is currently high, the historical dust volume in the previous control cycle, the current control cycle, and the next control cycle will be almost identical. The fan will operate in a relatively stable state until dust removal is complete. This situation will occur with dust highly adhered to the inner wall of the duct. In this case, the required vibration time will be longer. Because the historical dust volume is low, the third fan speed or current will also be lower, allowing the fan to operate in a more energy-efficient state.
[0024] In summary, using high wind speed and strong vibration to quickly remove dust, using low wind speed and weak vibration to quickly end the vibration dust removal process, and operating the fan in an energy-saving mode during the dust removal process are all beneficial to energy conservation and electrical safety.
[0025] Optionally, the historical dust removal amount in the previous control cycle is determined based on the first fan speed, the first fan current, the second fan speed, and the second fan current, including: determining the first dust amount corresponding to the first fan speed and the first fan current based on a preset correspondence model of fan speed and fan current; determining the second dust amount corresponding to the second fan speed and the second fan current based on the preset correspondence model of fan speed and fan current; and determining the historical dust removal amount based on the difference between the second dust amount and the first dust amount; wherein the preset correspondence model is set based on the fan model and the duct model.
[0026] The above technical solution can determine the overall dust removal effect of the previous control cycle when the fan speed is switched from the second fan speed to the first fan speed and the fan current gradually changes from the second fan current to the first fan current.
[0027] Alternatively, it can be determined that in the previous control cycle, the dust removal effect is as follows during the process of switching the fan current from the second fan current to the first fan current, and the fan speed gradually changing from the second fan speed to the first fan speed.
[0028] Optionally, the first dust quantity corresponding to the first fan speed and the first fan current is determined according to a preset correspondence model of fan speed and fan current, including: substituting the first fan speed into the preset correspondence model to obtain the first standard fan current output by the preset correspondence model, and determining the first dust quantity according to the first current difference between the first fan current and the first standard fan current.
[0029] Optionally, the first dust quantity corresponding to the first fan speed and the first fan current is determined according to a preset correspondence model of fan speed and fan current, including: substituting the first fan current into the preset correspondence model to obtain the first standard fan speed output by the preset correspondence model, and determining the first dust quantity according to the first speed difference between the first fan speed and the first standard fan speed.
[0030] Optionally, the second dust quantity corresponding to the second fan speed and the second fan current is determined according to a preset correspondence model of fan speed and fan current, including: substituting the second fan speed into the preset correspondence model to obtain the second standard fan current output by the preset correspondence model, and determining the second dust quantity according to the second current difference between the second fan current and the second standard fan current.
[0031] Optionally, the second dust quantity corresponding to the second fan speed and the second fan current is determined according to a preset correspondence model of fan speed and fan current, including: substituting the second fan current into the preset correspondence model to obtain the second standard fan speed output by the preset correspondence model, and determining the second dust quantity according to the second speed difference between the second fan speed and the second standard fan speed.
[0032] The above methods can obtain the first dust amount at the end of the previous control cycle and the second dust amount at the beginning of the previous control cycle.
[0033] Optionally, the third fan speed or third fan current in the current control cycle is determined based on the historical dust removal volume, including: determining the third fan speed that is positively correlated with the historical dust removal volume based on the correspondence between the historical dust removal volume and the third fan speed, or determining the third fan current that is positively correlated with the historical dust removal volume based on the correspondence between the historical dust removal volume and the third fan current.
[0034] Optionally, the third fan speed or third fan current in the current control cycle is determined based on the historical dust removal amount, including: determining the difference between the historical dust removal amount and the first dust removal amount threshold; determining the increase / decrease amount positively correlated with the difference dust removal amount; determining the increase / decrease value of the speed or the increase / decrease value of the current positively correlated with the increase / decrease value; determining the third fan speed based on the sum of the increase / decrease value of the speed and the first fan speed; or, determining the third fan current based on the sum of the increase / decrease value of the current and the first fan current.
[0035] The determined third fan speed or third fan current corresponds to the dust removal effect in the previous control cycle, which facilitates the rapid increase of fan speed or fan current in repeated control cycles to achieve rapid dust removal; or the rapid decrease of fan speed or fan current to achieve energy saving; or the maintenance of dust removal energy consumption at a level corresponding to the dust removal effect, and such continuous vibration to achieve energy saving.
[0036] Optionally, controlling the fan based on the third fan's speed or current includes: controlling the fan's operation for a preset duration based on the third fan's speed or current. This preset duration limits each control cycle, enabling the repeated execution of the control cycle.
[0037] Optionally, controlling the fan according to the speed of the third fan includes: determining a speed range based on the speed of the third fan, controlling the fan to increase from the lowest speed of the speed range to the highest speed of the speed range, or controlling the fan to decrease from the highest speed of the speed range to the lowest speed of the speed range, or controlling the fan to fluctuate within the speed range.
[0038] Optionally, the fan is controlled according to the third fan current, including: determining the current range based on the third fan current, controlling the fan to increase from the minimum speed of the current range to the maximum current of the current range, or controlling the fan to decrease from the maximum current of the current range to the minimum current of the current range, or controlling the fan to fluctuate within the current range.
[0039] Optionally, the dust removal method for pipelines based on wind-driven vibration further includes: terminating the pipeline dust removal process when the historical dust removal amount is less than or equal to the second dust removal amount threshold.
[0040] Optionally, the dust removal method for pipelines based on wind-driven vibration further includes: determining the cleanliness level based on the first fan speed and a fan speed threshold, or determining the cleanliness level based on the first fan current and a fan current threshold; and reminding the user of the content corresponding to the cleanliness level.
[0041] Optionally, the dust removal method for pipelines based on wind-driven vibration further includes: in the first control cycle, using a preset fan speed as the third fan speed, or using a preset fan current as the third fan current.
[0042] In some embodiments, a wind-driven vibration device is installed inside the duct to be dusted. The wind-driven vibration device is in working condition, and the duct is equipped with a corresponding fan that can drive the air flow inside the duct. The duct dust removal device based on wind-driven vibration includes an acquisition module, a first determination module, a second determination module, and a control module.
[0043] The acquisition module is used to obtain the first fan speed and the first fan current at the start of the current control cycle, and the second fan speed and the second fan current at the start of the previous control cycle; wherein, the first fan speed is the fan speed at the end of the previous control cycle, and the first fan current is the fan current at the end of the previous control cycle.
[0044] The first determining module is used to determine the historical dust removal amount in the previous control cycle based on the first fan speed, the first fan current, the second fan speed, and the second fan current.
[0045] The second determining module is used to determine the speed or current of the third fan in the current control cycle based on the historical dust removal volume; wherein, the speed of the third fan and the historical dust removal volume are positively correlated, or the current of the third fan and the historical dust removal volume are positively correlated.
[0046] The control module is used to control the fan according to the speed or current of the third fan, so as to adjust the wind speed in the duct and thus adjust the vibration effect of the wind-driven vibration device.
[0047] Similar to the dust removal method based on wind-driven vibration, this dust removal device based on wind-driven vibration can also achieve the following effects: rapid dust removal with high wind speed and strong vibration effect, quick end of the vibration dust removal process with low wind speed and weak vibration effect, and energy-saving operation of the fan during the dust removal process, all of which are beneficial to energy saving and electrical safety. The specific principles will not be elaborated here.

[0066] Figure 1 This is a schematic diagram of an implementation scenario of a ducted split air conditioner provided in an embodiment of this application.
[0067] Combination Figure 1 As shown, the indoor unit 11 of the air conditioner is usually installed in an indoor space, and is usually concealed, for example, it can be installed in the indoor ceiling 14, which can save the machine room area.
[0068] The indoor unit 11 of the air conditioner is connected to other rooms 15 without an indoor unit 11 through the air supply duct 12. After the air undergoes heat exchange in the indoor unit 11, it enters each room 15 through the air supply duct 12. An air valve is installed at the end of the air supply duct 12 in each room 15. By adjusting the opening of the air valve, the air volume entering the room 15 can be adjusted, thereby adjusting the indoor temperature.
[0069] The indoor unit 11 of the air conditioner absorbs air from each room 15 through the return air duct 13, and the air in the return air duct 13 and the supply air duct 12 exchange heat inside the indoor unit 11.
[0070] The cooling / heating principle of the ducted split air conditioner is similar to that of the ordinary split air conditioner. It consists of an indoor unit 11 and an outdoor unit (not shown in the figure), which are connected by copper pipes during installation.
[0071] The static pressure at the air outlet of the indoor unit 11 of a ducted split air conditioner is higher than that at the air outlet of the indoor unit of a regular split air conditioner; the single unit capacity of a ducted split air conditioner is also relatively large, generally available in various specifications such as 5 horsepower, 8 horsepower, 10 horsepower, and 12.5 horsepower; the length of the copper pipe that can be connected between the indoor unit 11 and the outdoor unit of a ducted split air conditioner is also longer, generally up to 50m, and the height difference between the indoor and outdoor units can reach 20m.
[0072] The air-driven vibration device 16 can be installed in the air supply duct 12, or the air-driven vibration device 16 can be installed in the return air duct 13 (not shown in the figure), or the air-driven vibration device 16 can be installed in both the air supply duct 12 and the return air duct 13 (not shown in the figure).
[0073] The wind-driven vibration device 16 can be installed on the inside or outside of a pipeline and fixed relative to the pipeline. When the wind-driven vibration device 16 vibrates, it can drive the pipeline to vibrate simultaneously.
[0074] Combination Figure 2a and 2b As shown, the wind-driven vibration device consists of a vibrating plate 21, a power unit 22, and a support rod 23.
[0075] The power unit 22 can be installed on the inner wall of the pipe.
[0076] The vibrating plate 21 is thin at one end and thick at the other.
[0077] The thin end of the vibrating plate 21 may be provided with a curved edge (not shown in the figure) to facilitate operation such as... Figure 2a Under the wind direction A shown, the vibrating plate 21 is less likely to vibrate, while... Figure 2b The wind direction A shown makes the vibrating plate 21 more prone to vibration.
[0078] Of course, in another case, by adjusting the shape of the thin and thick ends of the vibrating plate 21, so that it can... Figure 2a As shown, when the wind is downward, vibrations are easily generated; while in... Figure 2b Under wind direction A as shown, vibrations are less likely to occur.
[0079] Those skilled in the art can set it up according to their own experience.
[0080] The power unit 22 can drive the vibrating plate 21 to rotate, thereby switching the wind-driven vibration device between a vibrating state and a non-vibrating state. When the wind-driven vibration device is in the vibrating state, it is in the working state; when the wind-driven vibration device is in the non-vibrating state, it is in the non-working state.
[0081] Combined Figures 2c to 2e As shown, the wind-driven vibration device consists of a power unit 22 and a rotating device 24 (such as...). Figure 2c It consists of a polarizing block 25 and a support rod 23, as shown in the figure.
[0082] The support rod 23, the rotating device 24, and the polarizing block 25 are relatively fixed. Driven by wind, the rotating device 24 can rotate, which in turn drives the polarizing block 25 to rotate and generate vibration.
[0083] The power unit 22 can be installed on the inner wall of the pipe, and the power unit 22 can drive the support rod 23 and the rotating device 24. Figure 2d and Figure 2e The two states are shown in the diagram.
[0084] In such Figure 2d Under wind direction C as shown, the wind-driven vibration device is in operation and can drive the pipeline to vibrate; in such a wind direction C... Figure 2e Under wind direction C, the wind-driven vibration device is in a non-operating state.
[0085] Of course, the two wind-driven vibration devices listed above are merely illustrative examples. Those skilled in the art can also select other wind-driven vibration devices based on their own experience. The dust removal method for pipelines based on wind-driven vibration in this application does not make specific requirements in this regard.
[0086] This application uses a ducted split air conditioner as an example for illustrative purposes. The duct dust removal method based on wind-driven vibration can also be applied to other scenarios with the necessary hardware, such as central air conditioning.
[0087] Figure 3 This is a schematic flowchart of a pipe dust removal method based on wind-driven vibration provided in an embodiment of this application. A wind-driven vibration device is installed inside the pipe to be dusted, and the wind-driven vibration device is in working condition. A corresponding fan is installed in the pipe to drive the airflow inside the pipe.
[0088] The dust removal method for pipes based on wind-driven vibration can be implemented through a fan controller. When the fan is a fan in a specific device, the multi-pipe vibration dust removal method can be implemented through the controller of the specific device. For example, when the fan is an indoor fan of an air conditioner, the multi-pipe vibration dust removal method can be implemented through the controller of the air conditioner. Even in a smart home system, the multi-pipe vibration dust removal method can be executed through the server of the smart home system.
[0089] Combination Figure 3 As shown, the dust removal method for pipelines based on wind-driven vibration includes:
[0090] S301. Obtain the first fan speed and the first fan current at the start of the current control cycle, and the second fan speed and the second fan current at the start of the previous control cycle.
[0091] The first fan speed is the fan speed at the end of the previous control cycle, and the first fan current is the fan current at the end of the previous control cycle. This indicates that the current control cycle is not the first control cycle.
[0092] The dust removal scheme for pipelines based on wind-driven vibration provided in this application is implemented by repeating multiple control processes in a loop. This application takes one loop (the current control loop) as an example to illustrate the dust removal process for pipelines consisting of multiple loops.
[0093] In the first control cycle, the third fan speed or the third fan current is determined directly in the following ways: the preset fan speed is used as the third fan speed, or the preset fan current is used as the third fan current.
[0094] Driven by a preset fan speed or preset fan current, the fan will generate a certain air velocity in the duct. Driven by this air velocity, the wind-driven vibration device will vibrate, thereby producing a certain dust removal effect. Those skilled in the art can set the preset fan speed or preset fan current accordingly, so as to start the first control cycle at the initial moment of entering the dust removal mode.
[0095] The number of cycles can be recorded. Before the number of cycles reaches the preset number, the control cycle continues to be executed repeatedly to continue the dust removal process in the pipeline. After the number of cycles reaches the preset number, the dust removal process in the pipeline ends.
[0096] Alternatively, after obtaining the historical dust removal amount in subsequent steps, if the historical dust removal amount is greater than the first dust removal amount threshold, the control loop is repeated to continue the pipeline dust removal process; if the historical dust removal amount is less than or equal to the second dust removal amount threshold, the pipeline dust removal process is terminated.
[0097] S302. Determine the historical dust removal volume in the previous control cycle based on the first fan speed, the first fan current, the second fan speed, and the second fan current.
[0098] Historical dust removal volume is used to quantify the dust removal effect in the previous control cycle. The historical dust removal volume is determined by the second dust volume at the beginning of the previous control cycle and the first dust volume at the end of the previous control cycle. For example, the historical dust removal volume can be obtained by subtracting the first dust volume from the second dust volume.
[0099] The first dust volume is negatively correlated with the first fan speed and positively correlated with the first fan current; the second dust volume is negatively correlated with the second fan speed and positively correlated with the second fan current.
[0100] Those skilled in the art can obtain, through experimentation, the specific correspondence between the first dust quantity and the first fan speed and the first fan current, as well as the specific correspondence between the second dust quantity and the second fan speed and the second fan current.
[0101] Alternatively, after obtaining multiple sets of data on fan current, fan speed, and dust volume through repeated experiments, the specific correspondence between the three can be obtained with the assistance of Artificial Neutral Network (ANN) and Large Language Model (LLM).
[0102] After obtaining the specific correspondence between the fan current, fan speed, and dust amount, the first fan speed and the first fan current are substituted into the correspondence to obtain the first dust amount; the second fan speed and the second fan current are substituted into the correspondence to obtain the second dust amount.
[0103] Alternatively, after obtaining multiple sets of data on fan current, fan speed, and dust volume through repeated experiments, the correspondence between the first fan speed, first fan current, second fan speed, and second fan current and the historical dust removal volume can be directly obtained with the assistance of artificial neural networks and large language models.
[0104] During application, the first fan speed, the first fan current, the second fan speed, and the second fan current can be directly substituted into the corresponding relationship to obtain the historical dust removal volume.
[0105] S303. Determine the speed or current of the third fan in the current control cycle based on the historical dust removal volume.
[0106] Among them, the rotational speed of the third fan and the historical dust removal volume are positively correlated, or the current of the third fan and the historical dust removal volume are positively correlated.
[0107] The historical dust removal volume can be proportionally calculated, and the result of the proportional calculation can be used as the speed of the third fan. Alternatively, the historical dust removal volume can be proportional-differentially calculated, that is, the historical dust removal volume can be processed by the proportional-differential (PD) algorithm, and the result can be used as the speed of the third fan.
[0108] The historical dust removal volume can be proportionally calculated, and the result of the proportional calculation can be used as the current of the third fan. Alternatively, the historical dust removal volume can be proportionally-differentially calculated, that is, the historical dust removal volume can be processed by the proportional-differential (PD) algorithm, and the result can be used as the current of the third fan.
[0109] Of course, the proportional term, or proportional term and differential term required in determining the speed of the third fan, will be different from the proportional term, or proportional term and differential term required in determining the current of the third fan. Those skilled in the art can set them based on experience.
[0110] Optionally, the third fan speed or third fan current in the current control cycle is determined based on the historical dust removal volume, including: determining the third fan speed that is positively correlated with the historical dust removal volume based on the correspondence between the historical dust removal volume and the third fan speed, or determining the third fan current that is positively correlated with the historical dust removal volume based on the correspondence between the historical dust removal volume and the third fan current.
[0111] Optionally, the third fan speed or third fan current in the current control cycle is determined based on the historical dust removal amount, including: determining the difference between the historical dust removal amount and the first dust removal amount threshold; determining the increase / decrease amount positively correlated with the difference dust removal amount; determining the increase / decrease value of the speed or the increase / decrease value of the current positively correlated with the increase / decrease value; determining the third fan speed based on the sum of the increase / decrease value of the speed and the first fan speed; or, determining the third fan current based on the sum of the increase / decrease value of the current and the first fan current.
[0112] In some specific application scenarios, the aforementioned increases in speed and current can be represented by positive numbers; the aforementioned decreases in speed and current can be represented by negative numbers.
[0113] The sum of the speed increase / decrease value and the speed of the first fan can be used as the speed of the third fan; or, the sum of the speed increase / decrease value and the speed of the first fan can be fine-tuned, and the fine-tuned value can be used as the speed of the third fan; wherein, fine-tuning the sum of the speed increase / decrease value and the speed of the first fan includes: increasing or decreasing the sum of the speed increase / decrease value and the speed of the first fan.
[0114] The sum of the current increase / decrease value and the first fan current can be used as the third fan current; or, the sum of the current increase / decrease value and the first fan current can be fine-tuned, and the fine-tuned value can be used as the third fan current; wherein, fine-tuning the sum of the current increase / decrease value and the first fan current includes: increasing or decreasing the sum of the current increase / decrease value and the first fan current.
[0115] The determined third fan speed or third fan current corresponds to the dust removal effect in the previous control cycle, which facilitates the rapid increase of fan speed or fan current in repeated control cycles to achieve rapid dust removal; or the rapid decrease of fan speed or fan current to achieve energy saving; or the maintenance of dust removal energy consumption at a level corresponding to the dust removal effect, and such continuous vibration to achieve energy saving.
[0116] S304. Control the fan according to the speed or current of the third fan to adjust the wind speed in the duct, thereby adjusting the vibration effect of the wind-driven vibration device.
[0117] For example, during the process of controlling the fan speed based on the third fan speed, the fan current can vary freely as long as it is sufficient to support the fan speed. Of course, the freely varying fan current constitutes one of the judgment factors used to evaluate the dust removal effect of the current control cycle in the next control cycle.
[0118] During the process of controlling the fan current based on the third fan current, the fan speed can be freely varied, based on what the fan current can support. Of course, the freely varied fan speed constitutes one of the judgment factors for evaluating the dust removal effect of the current control cycle in the next control cycle.
[0119] The dust removal method for pipelines based on wind-driven vibration provided in this application is executed cyclically. Each control cycle can be executed for a preset duration, or the power consumption of each control cycle can be set to a preset amount. Those skilled in the art can also set the termination condition for each control cycle based on experience, so that multiple control cycles can be executed repeatedly.
[0120] The dust removal method for pipelines based on wind-driven vibration provided in this application can achieve the following technical effects:
[0121] The second fan speed and the second fan current are the fan states at the beginning of the previous control cycle, while the first fan speed and the first fan current are the fan states at the end of the previous control cycle.
[0122] The first fan speed and the first fan current can represent the amount of dust in the pipe at the beginning of the previous control cycle; the second fan speed and the second fan current can represent the amount of dust in the pipe at the end of the previous control cycle.
[0123] Thus, the historical dust removal volume determined based on the first fan speed, the first fan current, the second fan speed, and the second fan current can represent the dust removal result in the previous control cycle, that is, the result achieved by the following process: the wind speed generated in the pipeline by the second fan speed or the second fan current causes the wind-driven vibration device to achieve a vibration effect, which causes the pipeline to vibrate, and the dust on the inner wall of the pipeline is peeled off and blown away by the wind.
[0124] In other words, the second fan speed or the second fan current can also indicate the vibration effect of the wind-driven vibration device and the resulting dust removal effect. Generally speaking, the higher the second fan speed or the second fan current, the higher the air velocity in the pipeline, the greater the vibration amplitude of the wind-driven vibration device, and the better its dust removal effect.
[0125] In the current control loop, the determined third fan speed or third fan current has a positive correlation with the total amount of dust. If this third fan speed or third fan current is used to control the fan, the following situation will occur:
[0126] If the historical dust volume is high, and the current total dust volume is also high, and assuming that the dust removal process in the current control loop will not change the total dust volume from "high" to "low," then the current control loop will use a higher third fan speed or current. This higher third fan speed or current will result in a higher air velocity in the duct, leading to a stronger vibration effect from the wind-driven vibration device. The higher air velocity and stronger vibration effect result in better dust removal from the duct. Consequently, the historical dust volume determined in the next control loop (the control loop following the current one) will be even higher (using the historical dust volume determined in the current control loop as a comparison benchmark). The third fan speed or current determined in the next control loop will be even higher, further increasing the dust removal effect. This cycle repeats, which helps to reduce the total dust content relatively quickly.
[0127] If the historical dust volume is large, but the current total dust volume is small, the current control cycle will use a lower third fan speed or current. This lower speed or current will result in lower air velocity in the duct, leading to weaker vibration from the wind-driven vibration device. The lower air velocity and weaker vibration further reduce dust removal efficiency. Consequently, the historical dust volume determined in the next control cycle will be even smaller, resulting in a lower third fan speed or current and further weakened dust removal. This cycle repeats, helping to terminate the dust removal process more quickly and reducing instances of particularly poor or ineffective dust removal.
[0128] If the historical dust volume is relatively low, and the current total dust volume is also relatively low, then referring to the above analysis of "the historical dust volume is relatively high, and the current total dust volume is relatively low", the dust removal process will be terminated more quickly, in order to reduce dust removal processes that are particularly poor or even ineffective.
[0129] If the historical dust volume is relatively low, but the total dust volume is currently high, the historical dust volume in the previous control cycle, the current control cycle, and the next control cycle will be almost identical. The fan will operate in a relatively stable state until dust removal is complete. This situation will occur with dust highly adhered to the inner wall of the duct. In this case, the required vibration time will be longer. Because the historical dust volume is low, the third fan speed or current will also be lower, allowing the fan to operate in a more energy-efficient state.
[0130] In summary, using high wind speed and strong vibration to quickly remove dust, using low wind speed and weak vibration to quickly end the vibration dust removal process, and operating the fan in an energy-saving mode during the dust removal process are all beneficial to energy conservation and electrical safety.
[0131] Figure 4 This is a schematic flowchart of a pipe dust removal method based on wind-driven vibration provided in an embodiment of this application. A wind-driven vibration device is installed inside the pipe to be dusted, and the wind-driven vibration device is in working condition. A corresponding fan is installed in the pipe to drive the airflow inside the pipe.
[0132] The dust removal method for pipes based on wind-driven vibration can be implemented through a fan controller. When the fan is a fan in a specific device, the multi-pipe vibration dust removal method can be implemented through the controller of the specific device. For example, when the fan is an indoor fan of an air conditioner, the multi-pipe vibration dust removal method can be implemented through the controller of the air conditioner. Even in a smart home system, the multi-pipe vibration dust removal method can be executed through the server of the smart home system.
[0133] Combination Figure 4 As shown, the dust removal method for pipelines based on wind-driven vibration includes:
[0134] S401. Obtain the first fan speed and the first fan current at the start of the current control cycle, and the second fan speed and the second fan current at the start of the previous control cycle.
[0135] Wherein, the first fan speed is the fan speed at the end of the previous control cycle, and the first fan current is the fan current at the end of the previous control cycle.
[0136] S402. Based on the preset correspondence model between fan speed and fan current, determine the first dust quantity corresponding to the first fan speed and the first fan current.
[0137] The preset corresponding model is set based on the fan model and the pipe model. The pipe model refers to the pipe model under dust-free conditions.
[0138] Of course, in this preset corresponding model, the first dust amount is still negatively correlated with the first fan speed and positively correlated with the first fan current. In this way, the first dust amount at the end of the previous cycle and the beginning of the current cycle can be obtained.
[0139] Optionally, the first dust quantity corresponding to the first fan speed and the first fan current is determined according to a preset correspondence model of fan speed and fan current, including: substituting the first fan speed into the preset correspondence model to obtain the first standard fan current output by the preset correspondence model, and determining the first dust quantity according to the first current difference between the first fan current and the first standard fan current.
[0140] Alternatively, based on a preset correspondence model of fan speed and fan current, determine the first dust quantity corresponding to the first fan speed and the first fan current, including: substituting the first fan current into the preset correspondence model to obtain the first standard fan speed output by the preset correspondence model, and determining the first dust quantity based on the first speed difference between the first fan speed and the first standard fan speed.
[0141] The first current difference is positively correlated with the first dust amount. In a specific scenario, the first standard fan current will be less than the first fan current. The greater the first dust amount, the smaller the first standard current calculated according to the preset corresponding model.
[0142] The positive correlation between the first current difference and the first dust amount can be obtained theoretically based on the fan model and the pipeline model, or it can be obtained through experiments, or it can be obtained through theoretical derivation and experimental correction.
[0143] The first speed difference is positively correlated with the first dust amount. In a specific scenario, the first standard fan speed will be greater than the first fan speed. The greater the first dust amount, the greater the first standard fan speed calculated according to the preset corresponding model.
[0144] The positive correlation between the first speed difference and the first dust amount can be obtained theoretically based on the fan model and the pipeline model, or it can be obtained through experiments, or it can be obtained through theoretical derivation and experimental correction.
[0145] S403. Based on the preset correspondence model between fan speed and fan current, determine the second dust quantity corresponding to the second fan speed and the second fan current.
[0146] Of course, in this preset corresponding model, the second dust amount is still negatively correlated with the second fan speed and positively correlated with the second fan current. In this way, the second dust amount at the beginning of the previous cycle can be obtained.
[0147] Optionally, the second dust quantity corresponding to the second fan speed and the second fan current is determined according to a preset correspondence model of fan speed and fan current, including: substituting the second fan speed into the preset correspondence model to obtain the second standard fan current output by the preset correspondence model, and determining the second dust quantity according to the second current difference between the second fan current and the second standard fan current.
[0148] Alternatively, based on a preset correspondence model of fan speed and fan current, determine the second dust quantity corresponding to the second fan speed and the second fan current, including: substituting the second fan current into the preset correspondence model to obtain the second standard fan speed output by the preset correspondence model, and determining the second dust quantity based on the second speed difference between the second fan speed and the second standard fan speed.
[0149] The second current difference is positively correlated with the second dust amount. In a specific scenario, the second standard fan current will be less than the second fan current; the greater the second dust amount, the smaller the second standard current calculated according to the preset corresponding model.
[0150] The positive correlation between the second current difference and the second dust amount can be obtained theoretically based on the fan model and the pipeline model, or it can be obtained through experiments, or it can be obtained through theoretical derivation and experimental correction.
[0151] The second speed difference is positively correlated with the second dust amount. In a specific scenario, the second standard fan speed will be greater than the second fan speed. The greater the second dust amount, the greater the second standard fan speed calculated according to the preset corresponding model.
[0152] The positive correlation between the second speed difference and the second dust amount can be obtained theoretically based on the fan model and the pipeline model, or it can be obtained through experiments, or it can be obtained through theoretical derivation and experimental correction.
[0153] S404. Determine the historical dust removal amount based on the difference between the second dust amount and the first dust amount.
[0154] The above technical solution can determine the overall dust removal effect of the previous control cycle when the fan speed is switched from the second fan speed to the first fan speed and the fan current gradually changes from the second fan current to the first fan current.
[0155] Alternatively, it can be determined that in the previous control cycle, the dust removal effect is as follows during the process of switching the fan current from the second fan current to the first fan current, and the fan speed gradually changing from the second fan speed to the first fan speed.
[0156] This dust removal effect refers to the actual dust removal effect.
[0157] S405. Determine the speed or current of the third fan in the current control cycle based on the historical dust removal volume.
[0158] Among them, the rotational speed of the third fan and the historical dust removal volume are positively correlated, or the current of the third fan and the historical dust removal volume are positively correlated.
[0159] S406. Control the fan according to the speed or current of the third fan to adjust the wind speed in the duct, thereby adjusting the vibration effect of the wind-driven vibration device.
[0160] The process of controlling the fan based on the third fan or the current of the third fan will be described below as an example.
[0161] Optionally, controlling the fan based on the third fan's speed or current includes: controlling the fan's operation for a preset duration based on the third fan's speed or current. This preset duration limits each control cycle, enabling the repeated execution of the control cycle.
[0162] This preset duration can be used to define different control cycles. Those skilled in the art can set it based on experience.
[0163] Furthermore, the preset duration can be determined based on the degree of dust adhesion to the pipe. The higher the degree of dust adhesion, the less likely the dust is to fall off, and thus the longer the preset duration; conversely, the lower the degree of dust adhesion, the easier the dust is to fall off, and thus the shorter the preset duration. Setting the preset duration in this way allows for faster control of the circulation speed while ensuring that the historical dust volume is relatively considerable and measurable. This facilitates a more rapid match between the vibration effect generated by the wind-driven vibration device and the amount of dust in the pipe, thereby promoting the following effects:
[0164] Using high wind speed and strong vibration to quickly remove dust, and using low wind speed and weak vibration to quickly end the vibration dust removal process, as well as operating the fan in an energy-saving mode during the dust removal process, are all beneficial to energy conservation and electrical safety.
[0165] Optionally, controlling the fan according to the speed of the third fan includes: determining a speed range based on the speed of the third fan, controlling the fan to increase from the lowest speed of the speed range to the highest speed of the speed range, or controlling the fan to decrease from the highest speed of the speed range to the lowest speed of the speed range, or controlling the fan to fluctuate within the speed range.
[0166] Optionally, the fan is controlled according to the third fan current, including: determining the current range based on the third fan current, controlling the fan to increase from the minimum speed of the current range to the maximum current of the current range, or controlling the fan to decrease from the maximum current of the current range to the minimum current of the current range, or controlling the fan to fluctuate within the current range.
[0167] By adopting such a fluctuating fan control method, the air speed in the pipeline can fluctuate, and the vibration effect of the wind-driven vibration device can fluctuate, which is conducive to dust removal.
[0168] Specifically, the aforementioned preset duration for limiting the fan control process, and the specific speed and current for limiting the fan control process, can be combined.
[0169] For example: determine the speed range based on the speed of the third fan, and control the fan to increase from the lowest speed of the speed range to the highest speed of the speed range within a preset time period, or control the fan to decrease from the highest speed of the speed range to the lowest speed of the speed range within a preset time period, or control the fan to fluctuate within the speed range within a preset time period.
[0170] Alternatively, the current range can be determined based on the current of the third fan, and the fan can be controlled to increase from the minimum speed of the current range to the maximum current of the current range within a preset time period; or, the fan can be controlled to decrease from the maximum current of the current range to the minimum current of the current range within a preset time period; or, the fan can be controlled to fluctuate within the current range within a preset time period.
[0171] Of course, in the process of controlling the fan, the wind speed in the duct needs to be kept below the maximum wind speed that the wind-driven vibration device can withstand, so as to ensure the safety of the wind-driven vibration device.
[0172] Optionally, the dust removal method for pipelines based on wind-driven vibration further includes: determining the cleanliness level based on the first fan speed and a fan speed threshold, or determining the cleanliness level based on the first fan current and a fan current threshold; and reminding the user of the content corresponding to the cleanliness level.
[0173] The fan speed threshold and the fan current threshold are used to represent the preset cleanliness level. The fan speed threshold and the fan current threshold can be used to represent the cleanliness level under ideal conditions; or, they can be used to represent the cleanliness level acceptable to the user; or, other cleanliness levels determined by those skilled in the art based on actual needs can also be represented by the fan speed threshold or the fan current threshold.
[0174] On the one hand, the dust removal effect of the wind-driven vibration device is limited; on the other hand, in the specific application scenarios of air conditioning, filters are usually installed, and the cleanliness of the filters themselves will also affect the overall cleanliness.
[0175] The aforementioned dust removal process is based on historical dust removal volumes, which are relative quantities and cannot accurately measure the degree of cleanliness. Therefore, fan speed thresholds or fan current thresholds are used to measure the overall cleanliness effect, allowing users to perform relevant operations according to their needs, such as using other methods for duct dust removal, filter dust removal, and filter replacement.
[0176] Finally, the dust removal method for pipelines based on wind-driven vibration provided in this application embodiment is applied to, for example... Figure 1 In the scenario shown, a single fan can provide airflow to multiple pipes. Each pipe can be equipped with a damper, which controls the vibration effect of the air-driven vibration device in each pipe.
[0177] Figure 5 This is a schematic diagram of a pipe dust removal device based on wind-driven vibration, provided in an embodiment of this application. This wind-driven vibration-based pipe dust removal device can be implemented through software, hardware, or a combination of both.
[0178] The dust removal duct is equipped with a wind-driven vibration device. When the wind-driven vibration device is in operation, the duct is equipped with a corresponding fan that can drive the air flow inside the duct.

[0180] The module 51 is used to obtain the first fan speed and the first fan current at the start of the current control cycle, and the second fan speed and the second fan current at the start of the previous control cycle; wherein, the first fan speed is the fan speed at the end of the previous control cycle, and the first fan current is the fan current at the end of the previous control cycle.
[0181] The first determining module 52 is used to determine the historical dust removal amount in the previous control cycle based on the first fan speed, the first fan current, the second fan speed, and the second fan current.
[0182] The second determining module 53 is used to determine the speed of the third fan or the current of the third fan in the current control cycle based on the historical dust removal volume; wherein, the speed of the third fan and the historical dust removal volume are positively correlated, or the current of the third fan and the historical dust removal volume are positively correlated.
[0183] The control module 54 is used to control the fan according to the speed or current of the third fan, so as to adjust the wind speed in the duct and thus adjust the vibration effect of the wind-driven vibration device.
[0184] Similar to the dust removal method based on wind-driven vibration, this dust removal device based on wind-driven vibration can also achieve the following effects: rapid dust removal with high wind speed and strong vibration effect, quick end of the vibration dust removal process with low wind speed and weak vibration effect, and energy-saving operation of the fan during the dust removal process, all of which are beneficial to energy saving and electrical safety.
