Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioning maintenance technology for communication equipment rooms, and in particular to a dust removal device and dust removal control method. Background Technology
[0002] Currently, communication equipment rooms widely use air-cooled air conditioners (which include a fresh air system) to maintain the temperature at a preset level. The outdoor unit of this type of air conditioner must have a very fine filter to filter dust, sand, catkins, and other debris to prevent them from entering the equipment room and thus ensure the temperature is maintained at the preset level. However, during sandstorms, a large amount of dust adheres to the filter, severely clogging it and significantly reducing the airflow, causing the temperature in the communication equipment room to fail to maintain the preset level.
[0003] Therefore, to ensure that the temperature in the communication equipment room is maintained at the preset temperature, existing technology uses manual cleaning of the outdoor unit's filter. However, in northern regions from March to May, sandstorms and poplar catkins occur simultaneously, exacerbating the clogging of the outdoor unit's filter. This requires maintenance personnel to visit the site daily to rinse and remove debris from the filter, increasing the workload of filter maintenance and posing a risk of overheating and loss of control in the communication equipment room.
[0004] In addition, existing technologies can also clean the outdoor unit filter by reversing the outdoor unit fan and vibrating it to ensure that the temperature of the communication equipment room can be maintained at the preset temperature. However, when vibrating the outdoor unit filter, this method uses metal to directly strike metal objects, resulting in a crisp sound and high noise levels, which may cause disturbance to residents.
[0005] Therefore, existing technologies for cleaning outdoor unit filters present problems such as high maintenance workload, risk of high-temperature runaway, and disturbance to residents. Summary of the Invention

[0016] The inner side of the second movable elbow is connected to the upper part of the second flying disc via the third spring, and the outer side of the second movable elbow is connected to the lower part of the second flying disc via the fourth spring.
[0017] In one possible implementation, the dust removal device further includes a connector between each movable elbow and its corresponding groove; wherein the contact area between each connector and its corresponding groove is smaller than the opening area of the corresponding groove of each connector.
[0018] In one possible implementation, each spring is used to extend or retract when the overlapping flywheel drives the at least one movable elbow to rotate, causing the corresponding non-metallic ball to contact the convex surface.
[0019] In one possible implementation, the vibrator is located at any of the front, back, left, and right sides of the filter.
[0020] In one possible implementation, the dust removal device further includes a wind pressure sensor located inside the filter screen.
[0021] In one possible implementation, if the current wind pressure detected by the wind pressure sensor is lower than a first preset threshold, the motor starts a high-frequency dust removal mode.
[0022] If the current wind pressure is lower than the second preset threshold and not lower than the first preset threshold, the motor will start the low-frequency dust removal mode.
[0023] If the current wind pressure is not lower than the second preset threshold, the motor will shut down the dust removal device.
[0024] Secondly, this application also provides a dust control method, comprising:
[0025] The current wind pressure is detected by the wind pressure sensor in the dust removal device;
[0026] Based on the comparison result between the current wind pressure and the preset threshold, the motor in the dust removal device is controlled to adopt the dust removal mode set according to the comparison result.
[0027] In one possible implementation, the preset threshold includes a first preset threshold and a second preset threshold, and the dust removal mode includes a high-frequency dust removal mode and a low-frequency dust removal mode. Then, controlling the motor in the dust removal device to adopt the dust removal mode set according to the comparison result includes:
[0028] If the comparison result indicates that the current wind pressure is lower than the first preset threshold, then the motor in the dust removal device is controlled to adopt the high-frequency dust removal mode;
[0029] If the comparison result is that the current wind pressure is lower than the second preset threshold and not lower than the first preset threshold, then the motor is controlled to adopt the low-frequency dust removal mode.

[0034] If the wind pressure change rate is greater than the wind pressure change rate threshold, and the continuous vibration time of the dust removal device does not reach the preset time, then the motor is controlled to start the low-frequency dust removal mode.

[0040] In the dust removal device provided in this application embodiment, a motor and a vibrator are connected via a motor rod. Within the vibrator, a corresponding movable elbow and a stacked flywheel are connected via grooves. A non-metallic ball is positioned at the top of each movable elbow. When this non-metallic ball, driven by the stacked flywheel, contacts a convex surface on the filter screen, it squeezes the convex surface, thereby vibrating the filter screen and shaking off debris. This achieves automatic cleaning of the filter screen, avoiding manual cleaning and reducing maintenance workload and the risk of high-temperature runaway in communication equipment rooms. Furthermore, the vibration effect of the non-metallic ball colliding with the convex surface reduces the noise associated with direct metal impacts on metal objects used in existing cleaning techniques, thus preventing disturbance to residents.

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The specific operational methods in the method embodiments can also be applied to the device embodiments or system embodiments.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

Furthermore, in the description of this application, terms such as "first" and "second" are used only for distinguishing the purpose of description and should not be construed as indicating or implying relative importance or order.
[0056] It should be noted that the dimensions and shapes of the figures in the accompanying drawings do not reflect actual proportions and are intended only to illustrate the content of this disclosure.
[0057] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0058] The filters at the outdoor air inlets of air-cooled air conditioners in communication equipment rooms are prone to clogging, making it difficult to maintain the preset temperature. To address this issue, existing technologies involve manual cleaning or cleaning the filters by reversing the outdoor unit's fan and vibrating the filter. On one hand, the manual cleaning method requires frequent on-site visits from maintenance personnel to remove debris, resulting in a large workload and the risk of overheating and potential filter failure. On the other hand, the method of reversing the outdoor unit's fan and vibrating the filter involves directly striking the filter with metal objects, which generates noise and disturbs residents.
[0059] Therefore, as Figure 1 As shown, this application proposes a dust removal device, which includes: a vibrator 1 and a motor 2 ( Figure 1 (Not shown); The motor 2 is connected to the vibrator 1 via a motor rod 21; the vibrator 1 includes a cascading flywheel 11 and at least one movable elbow 12; wherein each movable elbow 12 is connected to the cascading flywheel 11 via a corresponding groove 3, and a non-metallic ball 121 is provided at the apex of each movable elbow 12; the non-metallic ball 121 is used to contact the convex surface 4 on the filter screen, squeeze the convex surface 4, thereby generating a vibration effect on the filter screen to shake off the debris on the filter screen, realizing automatic cleaning of the filter screen, thus avoiding manual cleaning of the filter screen, reducing the workload of filter screen maintenance and the risk of high temperature runaway in the communication equipment room. Furthermore, when the non-metallic ball 121 collides with the convex surface 4 to generate a vibration effect on the filter screen, it can reduce the noise of the prior art of directly hitting metal objects with metal materials to clean the filter screen, thereby avoiding the problem of disturbing residents.
[0060] It should be noted that, in the embodiments of this application, as Figure 1 As shown, the top end of the movable elbow 12 is opposite to the motor rod 21. The size of the movable elbow 12 can be adjusted according to the internal space of the filter screen to facilitate the installation of the movable elbow 12 and the dust removal device, as well as the operation of the dust removal device.
[0061] The material of the aforementioned convex surface 4 can be the same as the material of the non-metallic ball 121.
[0062] Optionally, the non-metallic ball 121 provided at the top of each movable elbow 12 can be a low-noise smooth sphere, and the outer layer of the non-metallic ball 121 is wrapped with a layer of chemical material (such as rubber, plastic, etc.) to reduce the wear of the non-metallic ball 121 and thus extend the service life of the non-metallic ball 121; at the same time, it also reduces the noise generated during the dust removal process and avoids the problem of disturbing residents.
[0063] Optionally, the non-metallic ball 121 provided on the top of each movable push rod 12 can be installed by bolts. That is, the non-metallic ball 121 is installed on the top of each movable push rod 12 by bolts, so that the non-metallic ball 121 can be quickly removed and replaced after it is worn.
[0064] It should be noted that, in this embodiment, the diameter of the non-metallic ball 121 may or may not be the same as the width of the movable elbow 12. In this embodiment, the diameter (i.e., size) of the non-metallic ball 121 can be adjusted according to the specific application scenario to facilitate the installation and operation of the dust removal device.
[0065] Optional, such as Figure 2a As shown, the vibrator 1, which includes the movable elbow 12, can be located on the front of the filter screen. Figure 2a (The left side of the middle section shows the front of the filter). For example... Figure 2b As shown, the vibrator 1, which includes the movable elbow 12, can also be located on the back of the filter screen. Figure 2b (The left side of the middle section shows the front of the filter). For example... Figure 2c As shown, the vibrator 1, including the movable elbow 12, can also be located on the left side of the filter screen. Figure 2d As shown, the vibrator 1, which includes the movable elbow 12, can also be located on the right side of the filter screen. That is, the vibrator 1, which includes the movable elbow 12, can be located at any position on the front, back, left, or right side of the filter screen.
[0066] In this embodiment of the application, the position of the vibrator 1 can be adjusted according to the specific application scenario, so that the position of the vibrator 1 is flexible, thereby making the position of the dust removal device containing the vibrator 1 also flexible.
[0067] Furthermore, such as Figure 3a As shown, the cascading flywheel 11 includes a first fly disc 111 and a second fly disc 112, which are connected by a motor rod 21 to ensure that the first fly disc 111 and the second fly disc 112 rotate at the same speed, facilitating the cleaning of the filter screen. The first fly disc 111 is larger than the second fly disc 112, and is located below the second fly disc 112, making the dust removal device easy to install and allowing for control of the dust removal intensity.
[0068] The second flying disc 112 is a telescopic flying disc composed of a central disc 1121 and mutually independent blades 1122; the first flying disc 111 is a non-telescopic flying disc. In the embodiments of this application, the first flying disc 111 may be a fixed flying disc.
[0069] In this embodiment, the central disk 1121, blade 1122, and first flying disk 111 can be made of metal. The shape of the blade 1122 can be as follows: Figure 3a The fan-like characteristics shown are not limited to those of a fan. The shape of the blade 1122 can be adjusted according to specific application scenarios to provide a position for the installation of the movable elbow 12.
[0070] With the above structure, when the dust removal device based on the overlapping flywheel 11 composed of the first flywheel 111 and the second flywheel 112 removes dust from the filter screen, the dust removal intensity can be controlled to cope with different clogging conditions of the filter screen in different seasons, making the dust removal device flexible.
[0071] When the cascaded flywheel 11 stops working, as Figure 3b As shown, the blades 1122 of the second flying disc 112 naturally fall down under the influence of gravity.
[0072] In this embodiment of the application, when the cascading flywheel 11 stops working, this state is the closed state of the dust removal device.
[0073] When the rotational speed of the cascading flywheel 11 is not greater than the preset rotational speed, the opening angle of the blades 1122 of the second fly disc 112 is not greater than the preset angle. For example... Figure 3c As shown, the blades 1122 of the second disc 112 fail to fully open. At this time, the non-metallic ball 121 on the first movable elbow 12a of the first disc 111 touches the convex surface 4 on the filter screen to remove dust.
[0074] In this embodiment of the application, when the rotational speed of the cascading flywheel 11 is not greater than the preset rotational speed and the opening angle of the blades 1122 of the second fly disc 112 is not greater than the preset angle, the dust removal mode corresponding to this state is the low-frequency dust removal mode.
[0075] When the rotational speed of the cascading flywheel 11 is not less than the preset rotational speed, the opening angle of the blades 1122 of the second fly disc 112 is greater than the preset angle. For example... Figure 3a As shown, the blades 1122 of the second flying disc 112 are fully opened under the action of centrifugal force. At this time, the second movable elbow 12b on the second flying disc 112 and the first movable elbow 12a on the first flying disc 111 work simultaneously to enhance the dust removal effect.
[0076] In this embodiment of the application, when the rotational speed of the cascading flywheel 11 is not less than the preset rotational speed and the opening angle of the blades 1122 of the second fly disc 112 is greater than the preset angle, the dust removal mode corresponding to this state is the high-frequency dust removal mode.
[0077] Therefore, by setting the rotational speed of the motor rod 21, the rotational speeds of the first flying disc 111 and the second flying disc 112 can be adjusted to control the dust removal intensity. Based on the rotational speed settings, different dust removal modes (such as high-frequency dust removal mode and low-frequency dust removal mode) are provided to meet the dust removal needs of different seasons.
[0078] In one possible implementation, to ensure that the second movable elbow 12b on the second flying disc 112 and the first movable elbow 12a on the first flying disc 111 can both contact the convex surface 4 when they operate simultaneously, the distance between the second flying disc 112 and the first flying disc 111 (i.e., the connection length of the motor rod 21 between the second flying disc 112 and the first flying disc 111) is within a preset distance range. This preset distance is not greater than the diameter of the convex surface 4 and can be adjusted according to the diameter of the convex surface 4. The diameter of the convex surface 4 is the longest distance in the direction parallel to the motor rod 21. Figure 4a As shown, the diameter of the convex object 4 is H, and the connection length of the motor rod 21 between the second flying disc 112 and the first flying disc 111 is L.
[0079] In another possible implementation, so that when the second movable elbow 12b on the second frisbee 112 and the first movable elbow 12a on the first frisbee 111 are working simultaneously, the non-metallic balls 121 on both the second movable elbow 12b and the first movable elbow 12a can contact the convex surface 4, such as... Figure 4b As shown, the convex surface 4 includes a first convex surface 4a and a second convex surface 4b. The first convex surface 4a is provided at the contact position between the filter screen and the non-metallic ball 121 on the first movable elbow 12a, and the second convex surface 4b is provided at the contact position between the filter screen and the non-metallic ball 121 on the second movable elbow 12b.
[0080] Furthermore, such as Figure 3a As shown in this embodiment, the dust removal device further includes multiple springs 5. These multiple springs include at least a first spring 5a, a second spring 5b, a third spring 5c, and a fourth spring 5d. The movable elbow 12 includes a first movable elbow 12a and a second movable elbow 12b. Elbow 12a is a movable elbow connected to the first flying disc 111 via a corresponding groove 3, and the second movable elbow 12b is a movable elbow connected to the second flying disc 112 via a corresponding groove 3.
[0081] The inner side of the first movable elbow 12a is connected to the upper part of the first flying disc 111 via the first spring 5a, and the outer side of the first movable elbow 12a is connected to the lower part of the first flying disc 111 via the second spring 5b.
[0082] The inner side of the second movable elbow 12b is connected to the upper part of the second flying disc 112 via the third spring 5c, and the outer side of the second movable elbow 12b is connected to the lower part of the second flying disc 112 via the fourth spring 5d.
[0083] It should be noted that, in this embodiment, the placement of the spring 5 can be adjusted according to the specific application scenario.
[0084] Furthermore, the distance by which the first movable elbow 12a extends beyond the first flying disc 111 plus the radius of the first flying disc is equal to the sum of the diameter of the blade 1122 when fully open, the radius of the central disc 1121, and the distance by which the second movable elbow 12b extends beyond the blade 1122. This allows the blade 1122 in the dust removal device to be parallel to the filter screen when fully open, facilitating the installation and operation of the dust removal device. For example, as... Figure 3a As shown, the distance k1 of the first movable elbow 12a beyond the first flying disc 111 is k2, the radius of the first flying disc is k2, the distance k3 of the second movable elbow 12b beyond the blade 1122 is k4, the diameter of the blade 1122 when fully open is k4, and the radius of the central disc 1121 is k5. Then the sum of k1 and k2 is equal to the sum of k3, k4, and k5.
[0085] Optionally, in the embodiments of this application, such as Figure 5 As shown, the dust removal device also includes a connector 6 between each movable elbow 12 and its corresponding groove 3. When the dust removal device also includes multiple springs 5, the contact area between each connector 6 and its corresponding groove 3 is smaller than the opening area of the corresponding groove 3. This allows the movable elbow 12 to extend and retract in the groove 3 towards the motor rod 21 and away from the motor rod 21 during operation of the dust removal device. This ensures that when the non-metallic ball 121 touches the convex surface 4, the movable elbow 12 can smoothly pass through the convex surface 121. After passing through the convex surface 121, when the spring 5 retracts to its original state, it can pull the movable elbow 12 back to its original state, allowing the non-metallic ball 121 to squeeze the convex surface 4 again, thereby generating a vibration effect on the filter screen to achieve an automatic dust removal effect.
[0086] In this embodiment of the application, when the contact area between each connector 6 and the corresponding groove 3 is smaller than the opening area of the corresponding groove 3 of each connector, the groove 3 may be a sliding groove.
[0087] Optionally, in this embodiment, when the contact area between each connector 6 and the corresponding groove 3 in the dust removal device is smaller than the opening area of the corresponding groove 3 of each connector, each spring 5 in the dust removal device is used to perform telescopic movement when the covered flywheel 11 drives at least one movable elbow 12 to rotate so that the corresponding non-metallic ball 121 touches the convex surface 4.
[0088] like Figure 6 As shown, when motor 2 starts, motor rod 21 begins to rotate, causing the covered flywheel 11 to rotate. Under the rotation of the covered flywheel 11, the non-metallic ball 121 on the movable elbow 12 can contact the convex surface 4. When the non-metallic ball 121 contacts the convex surface 4, it compresses the convex surface 4. Similarly, when the non-metallic ball 121 compresses the convex surface 4, the convex surface 4 also generates a reaction force on the non-metallic ball 121, causing the movable elbow 12 to slide towards motor rod 21 through groove 3. Simultaneously, as the movable elbow 12 slides towards motor rod 21 through groove 3, it compresses spring 5, causing spring 5 to deform. After the non-metallic ball 121 slides past the convex surface 4, spring 5 returns to its original state, allowing the movable elbow 12 to slide away from motor rod 21 through groove 3, so that the non-metallic ball 121 on the movable elbow 12 can continue to contact the convex surface 4. Therefore, the spring 5 and the movable elbow 12 move in extension and retraction under the drive of the overlapping flywheel 11, generating vibration to achieve the dust removal effect on the filter screen and improve the dust removal efficiency.
[0089] In this embodiment, the number of first movable elbows 12a on the first flying disc 111 and the number of second movable elbows 12b on the second flying disc 112 can be the same or different. Furthermore, the number of first movable elbows 12a on the first flying disc 111 and second movable elbows 12b on the second flying disc 112 can be dynamically increased or decreased according to the expected dust removal effect, thereby giving the dust removal device good flexibility to meet the dust removal needs of different application scenarios. Figure 3a In the schematic diagram of the dust removal device shown, four first movable elbows 12a are connected to the first flying disc 111, and four second movable elbows 12b are connected to the second flying disc 112.
[0090] Optionally, in this embodiment, the groove 3 in the dust removal device can also be a fixing groove, so that the movable elbow 12 is fixed on the overlapping flywheel 11. For example... Figure 1As shown, when the non-metallic ball 121 presses against the convex surface 4, the movable elbow 12 can pass through the convex surface 4. Since the movable elbow 12 is mounted on the cascading flywheel 11 via a fixed groove, it will not move in the direction of or away from the motor rod 21, nor will it swing left or right. Therefore, when the cascading flywheel 11 rotates, after the movable elbow 12 passes through the convex surface 4, the non-metallic ball 121 can continue to contact and press against the convex surface 4, thereby vibrating the filter screen to achieve a dust removal effect.
[0091] Because there is a lot of dust and other debris on the filter screen, the air pressure inside the filter screen is low. Therefore, the dust removal device in this embodiment may also include an air pressure sensor 7 located inside the filter screen to detect the air pressure in real time, thereby guiding the operation of the dust removal device.
[0092] Specifically, if the current wind pressure detected by the wind pressure sensor 7 is lower than the first preset threshold, the motor 2 activates the high-frequency dust removal mode. If the current wind pressure detected by the wind pressure sensor 7 is lower than the second preset threshold but not lower than the first preset threshold, the motor 2 activates the low-frequency dust removal mode. If the current wind pressure detected by the wind pressure sensor 7 is not lower than the second preset threshold, the motor 2 shuts off the dust removal device. The first preset threshold is less than the second preset threshold.
[0093] Furthermore, in this embodiment, when the wind pressure change rate is not greater than the wind pressure change rate threshold, motor 2 shuts down the dust removal device. When the wind pressure change rate is greater than the wind pressure change rate threshold, and the continuous vibration event of the dust removal device reaches a preset time, the dust removal device sends a warning message indicating dust removal failure, and motor 2 shuts down the dust removal device. When the wind pressure change rate is greater than the wind pressure change rate threshold, and the continuous vibration time of the dust removal device does not reach the preset time, motor 2 starts the low-frequency dust removal mode.
[0094] The rate of change of wind pressure can be calculated using the following formula:
[0095]
[0096] Where Ratio is the rate of change of wind pressure; P1 is the initial wind pressure; and P2 is the current wind pressure.
[0097] It should be noted that, in this embodiment of the application, the initial air pressure is the air pressure when the filter screen is not clogged with debris.
[0098] Based on the wind pressure sensor in the aforementioned dust removal device, the current wind pressure inside the filter can be detected in real time. This allows the device to be configured to operate in a specific mode (e.g., high-frequency or low-frequency dust removal) based on a preset threshold and the current wind pressure. When the relationship between the current wind pressure and the preset threshold meets preset conditions (e.g., the current wind pressure is below a first preset threshold, or below a second preset threshold but not below the first preset threshold), the dust removal device can automatically start without intervention from maintenance personnel. This reduces labor costs and ensures safety and reliability.
[0099] Based on the same inventive concept, this application also provides a dust removal control method for a dust removal device based on any of the foregoing embodiments. This method can be applied to a control system connected to the dust removal device to achieve control of the dust removal device. See also... Figure 7 As shown, the method includes:
[0100] S701: The current wind pressure is detected by the wind pressure sensor in the dust removal device.
[0101] In this embodiment, since the wind pressure sensor in the dust removal device is located inside the filter screen, the current wind pressure detected by the wind pressure sensor is the wind pressure inside the filter screen. Therefore, based on the wind pressure inside the filter screen, the clogging status of the filter screen can be determined, so that the dust removal device can clean the filter screen.
[0102] S702: Based on the comparison result between the current wind pressure and the preset threshold, control the motor in the dust removal device to adopt the dust removal mode set according to the comparison result.
[0103] The dust removal mode may include a high-frequency dust removal mode and a low-frequency dust removal mode; the preset threshold may include a first preset threshold and a second preset threshold, and the first preset threshold is lower than the second preset threshold.
[0104] When controlling the motor in the dust removal device to use the dust removal mode set according to the comparison result, if the comparison result is that the current air pressure is lower than the first preset threshold, then the motor in the dust removal device is controlled to use the high-frequency dust removal mode. If the comparison result is that the current air pressure is lower than the second preset threshold but not lower than the first preset threshold, then the motor is controlled to use the low-frequency dust removal mode.
[0105] It should be noted that, in this embodiment, after the control motor adopts the high-frequency dust removal mode, the current air pressure is detected in real time. When the detected current air pressure is lower than the second preset threshold but not lower than the first preset threshold, the control motor switches the high-frequency dust removal mode to the low-frequency dust removal mode.
[0106] In one possible implementation, the dust removal control method based on the aforementioned dust removal device further includes: if the comparison result is that the current wind pressure is not lower than a second preset threshold, then control the motor to shut down the dust removal device.
[0107] In one possible implementation, when the motor is controlled in low-frequency dust removal mode, the wind pressure change rate is first calculated based on the current and initial wind pressure. Next, it is determined whether the wind pressure change rate exceeds a threshold value. For example, the threshold value is 5%. If the wind pressure change rate exceeds the threshold value, it is further determined whether the continuous vibration time of the dust removal device has reached a preset time. If the continuous vibration time of the dust removal device has not reached the preset time when the wind pressure change rate exceeds the threshold value, the motor is controlled to start the low-frequency dust removal mode.
[0108] In another possible implementation, the dust removal control method based on the aforementioned dust removal device further includes: if the wind pressure change rate is not greater than the wind pressure change rate threshold, then control the motor to shut down the dust removal device.
[0109] In another possible implementation, the dust removal control method based on the aforementioned dust removal device further includes: when the wind pressure change rate is greater than the wind pressure change rate threshold, if the continuous vibration time reaches a preset time, a warning message indicating dust removal failure is sent, and the motor is controlled to shut down the dust removal device.
[0110] In summary, the dust control method based on the aforementioned dust removal device can be as follows: Figure 8 As shown, it includes:
[0111] S801: The current wind pressure is detected by the wind pressure sensor in the dust removal device, and it is determined whether the current wind pressure is lower than the first preset threshold.
[0112] If yes, proceed to step S802; otherwise, proceed to step S803.
[0113] S802: Controls the motor in the dust removal device to start the high-frequency dust removal mode.
[0114] After the control motor starts the high-frequency dust removal mode, the current wind pressure is detected in real time by the wind pressure sensor, and step S803 is executed.
[0115] S803: Determine whether the current wind pressure is lower than the second preset threshold.
[0116] If not, proceed to step S804; if yes, proceed to step S805.
[0117] S804: Control motor to shut down dust removal device.
[0118] S805: Controls the motor to start the low-frequency dust removal mode.
[0119] S806: Calculate the wind pressure change rate based on the current wind pressure and the initial wind pressure, and determine whether the wind pressure change rate is greater than the wind pressure change rate threshold.
[0120] If not, proceed to step S804; if yes, proceed to step S807.
[0121] S807: Determine whether the continuous vibration time of the dust removal device has reached the preset time.
[0122] If not, proceed to step S805; if yes, proceed to step S808.
[0123] S808: Sends a warning message indicating that the dust removal has failed.
[0124] After sending a warning message indicating that the dust removal has failed, proceed to step S804.
[0125] By employing the above method, the wind pressure sensor in the dust removal device can detect the current wind pressure inside the filter in real time. Then, based on the comparison between the current wind pressure and preset thresholds (such as a first preset threshold and a second preset threshold), the motor in the dust removal device is controlled to adopt the corresponding dust removal mode, thus initiating dust removal operations. This achieves automatic cleaning of the filter, avoiding manual cleaning and reducing maintenance workload. Furthermore, this method can maintain the temperature of the communication equipment room at a preset level, reducing the risk of overheating and potential runaway. Simultaneously, the dust removal control method described above avoids the noise generated by directly striking metal objects with metal materials, thus preventing disturbance to residents.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
