Description

Technical Field

[0001] This disclosure relates to the field of centralized smoke exhaust systems, and in particular to a fan control method, device, and electronic equipment in a centralized smoke exhaust system. Background Technology

[0002] The noise sources of centralized smoke extraction systems are mainly the operating noise and vibration noise of the outdoor unit's fan, as well as the air vibration noise generated by the fan's operation. This noise can backflow into users' homes through the smoke duct, resulting in a poor user experience. Current noise reduction technologies primarily involve adding sound-absorbing cotton to the fan casing or adding noise-reducing components inside the smoke duct. However, both of these methods are passive noise reduction. Using sound-absorbing cotton has poor noise reduction effects; adding noise-reducing components inside the smoke duct affects the smoke extraction efficiency. Therefore, these methods cannot achieve a balance between noise reduction and smoke extraction efficiency. Summary of the Invention

[0003] In view of the above-mentioned technical problems, this disclosure proposes a fan control method, device and electronic equipment in a centralized smoke exhaust system.

[0018] The floor information of the object is compared with the preset range of high-rise floors to obtain a second comparison result;

[0019] If the second comparison result indicates that the floor information of the object does not belong to the preset high-rise floor range, the fan is controlled to run at the current fan speed.

[0020] Optionally, adjusting the smoke extraction assembly based on the current fan speed range when the current fan noise information does not meet the current allowable noise range includes:

[0021] If the second comparison result indicates that there is floor information in the target floor information that belongs to the preset high-rise floor range, and the current fan noise information does not meet the current allowable noise range, the smoke exhaust component is adjusted based on the current fan speed range.

[0022] Optionally, after responding to the smoke exhaust start command of the target object and obtaining the current operating rate and the object damper angle corresponding to at least one activated object in the centralized smoke exhaust system, the method further includes:

[0023] If the current operating rate is less than the preset operating rate, the fan will not be turned on.

[0027] Optionally, the object damper angle corresponding to the at least one opened object includes the target object damper angle corresponding to the target object, and the target object damper angle is obtained in the following ways:

[0028] Obtain the target object floor information and the target object smoke exhaust level information;

[0029] Based on the floor information of the target object and the smoke exhaust level information, the angle of the air valve of the target object is determined.

[0030] According to another aspect of the present disclosure, a fan control device for a centralized smoke exhaust system is provided, the device comprising:

[0031] The first information acquisition module is used to respond to the smoke exhaust start command of the target object and acquire the current start-up rate and the angle of the object air valve corresponding to at least one activated object in the centralized smoke exhaust system.

[0032] The first information determination module is used to determine the current fan speed range based on the current operating rate and the angle of the object air valve;

[0035] The second execution module is used to adjust the smoke exhaust assembly based on the current fan speed range when the current fan noise information does not meet the current allowable noise range. The smoke exhaust assembly includes the fan, or the fan and the control box valve corresponding to the at least one opened object.

[0036] According to another aspect of the present disclosure, an electronic device is provided, comprising: a processor; and a memory for storing processor-executable instructions; wherein the processor is configured to execute the instructions to implement the fan control method in the centralized smoke exhaust system described above.

[0037] According to another aspect of the present disclosure, a computer-readable storage medium is provided, which, when the instructions in the storage medium are executed by a processor of an electronic device, enables the electronic device to perform the fan control method described above in a centralized smoke exhaust system.

[0038] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0039] In response to the smoke exhaust start command of the target object, the system obtains the current operating rate and the angle of the damper corresponding to at least one activated object in the centralized smoke exhaust system. Based on the current operating rate and the damper angle, the current fan speed range is determined, enabling the determination of a fan speed range that achieves good smoke exhaust effect. Combined with the current fan speed range, the current allowable noise range and the current fan speed are determined. Since the current fan speed falls within the current fan speed range, controlling the fan to operate at the current fan speed ensures the smoke exhaust effect of the centralized smoke exhaust system. Next, the system obtains the current fan noise information. If the current fan noise information does not meet the current allowable noise range, the smoke exhaust components are adjusted based on the current fan speed range. The smoke exhaust components include the fan, or the fan and the control box damper corresponding to at least one activated object, thereby achieving noise reduction while ensuring smoke exhaust effect, thus achieving a balance between smoke exhaust effect and noise reduction.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0050] Please see Figure 1 , Figure 1 This is a block diagram illustrating a centralized smoke extraction system according to an exemplary embodiment. Figure 1 As shown, a centralized smoke extraction system may include a main controller 1, an outdoor fan 2 installed on the rooftop, a common smoke duct 3, a smoke collection hood 4, a control box damper 5, and a noise sensor 6 installed on the aforementioned fan.

The fan 2 is used to exhaust the fumes in the common smoke duct 3 to the outside. The noise sensor 6 is used to collect the noise of the fan to obtain the current fan noise information.

[0051] Please see Figure 2 , Figure 2This is a flowchart illustrating a fan control method in a centralized smoke exhaust system according to an exemplary embodiment. For example... Figure 2 As shown, the fan control method in this centralized smoke exhaust system can be applied to centralized smoke exhaust systems, and specifically includes the following steps:

[0052] S201: In response to the smoke exhaust start command of the target object, obtain the current start-up rate and the angle of the object damper corresponding to at least one activated object in the centralized smoke exhaust system.

[0053] In one specific embodiment, the target object can refer to the object whose smoke extraction is currently activated. Specifically, the object may include a smoke hood. The smoke extraction start command can be used to instruct the corresponding smoke hood to activate its smoke extraction function. The smoke extraction start command may include the target object's floor information and the corresponding smoke extraction level information. Specifically, the user initiates the smoke extraction operation through the control panel to trigger the target object's smoke extraction start command; specifically, the user can trigger the target object's smoke extraction start command by pressing a preset level button.

[0054] In a specific embodiment, the current activation rate can refer to the proportion of smoke hoods currently activated in the centralized smoke exhaust system out of all smoke hoods in the system. Specifically, the current number of activated objects and the preset number of objects can be obtained first; dividing the current number of activated objects by the preset number of objects yields the current activation rate. Here, the current number of activated objects can refer to the number of at least one activated object; the at least one activated object can refer to objects in the centralized smoke exhaust system that currently have their smoke exhaust function activated; the preset number of objects can refer to the total number of objects included in the centralized smoke exhaust system. It is understood that the at least one activated object can include the target object.

[0055] In one specific embodiment, the object damper angle corresponding to at least one opened object can refer to the current damper angle of the control box damper corresponding to each of the at least one opened object. Specifically, in response to the smoke exhaust start command of the target object, the object damper angle can be obtained by detecting the angle of the control box damper corresponding to each of the at least one opened object.

[0056] In one specific embodiment, the object damper angle corresponding to at least one opened object may include the target object damper angle corresponding to the target object. Here, the target object damper angle may refer to the damper angle of the control box damper corresponding to the target object.

[0057] In a specific embodiment, the angle of the target object damper can be obtained in the following ways:

[0058] Obtain the target object's floor information and the target object's corresponding smoke exhaust level information;

[0059] Based on the floor information and smoke exhaust level information of the target object, determine the angle of the air valve of the target object.

[0060] In one specific embodiment, the target object floor information refers to the floor information where the target object is located in the centralized smoke exhaust system. The smoke exhaust level information corresponding to the target object can represent the required smoke exhaust air volume. Specifically, the target object floor information and the target object smoke exhaust level information can be obtained from the smoke exhaust start command corresponding to the target object.

[0061] In a specific embodiment, the angle of the target object damper can be obtained by the following formula:

[0062]

[0063] Wherein, θ is the angle of the target object's damper; f is the floor information of the target object; m is the smoke exhaust level information; k1, k2, a1, and a2 are preset parameters. Specifically, k1, k2, a1, and a2 can be set according to actual application needs, and this disclosure does not impose any limitations.

[0064] In the above embodiments, by combining the target object floor information and smoke exhaust level information, the angle of the target object's air valve can be determined, thereby achieving a balanced distribution of air volume for different objects and achieving a balanced smoke exhaust effect between different floors in a centralized smoke exhaust system.

[0065] S203: Determine the current fan speed range based on the current operating rate and the angle of the target air valve.

[0066] In a specific embodiment, the current fan speed range can refer to the range of speeds within which the fan can achieve a good smoke extraction effect at the current moment. The current fan speed range can include a minimum speed and a maximum speed within the current range. It is understood that a speed falling between the minimum and maximum speeds within the current range is considered to satisfy the aforementioned current fan speed range.

[0067] In a specific embodiment, the current wind turbine speed range can be determined by the following formula:

[0068]

[0069] Where N1 is the minimum speed in the current range; N2 is the maximum speed in the current range; η is the current operating rate; θ i f(θ1,θ2,…,θ) represents the valve angle of the i-th open object among at least one open object; n represents the number of objects with at least one open object;n ) is the fusion function; a3, a4, k3, k4, k5, and k6 are preset parameters. Specifically, the fusion function may include the mean function; k3, k4, k5, and k6 can be set according to actual application needs, and this disclosure does not limit them.

[0070] In one specific embodiment, the step S201 above may further include:

[0071] If the current operating rate is lower than the preset operating rate, the fan will not be turned on.

[0072] Open the control box damper corresponding to at least one activated object to the preset damper angle.

[0073] Accordingly, step S203 may include:

[0074] If the current operating rate is greater than or equal to the preset operating rate, the current fan speed range is determined based on the current operating rate and the angle of the target air valve.

[0075] In one specific embodiment, the preset power-on rate can be set according to actual application needs. Specifically, the preset power-on rate can range from 8% to 10%. Optionally, the preset power-on rate can be 9%.

[0076] In one specific embodiment, the preset damper angle can be in the range of 80 degrees to 90 degrees. Optionally, the preset damper angle can be 90 degrees. It can be understood that when the damper angle is 90 degrees, the air volume in the duct can be maximized; when the damper angle is reduced, the air volume in the duct will decrease accordingly; conversely, when the damper angle is increased, the air volume in the duct will increase accordingly.

[0077] In one specific embodiment, when the current operating rate is less than the preset operating rate, the fan can be controlled not to start, and the control box damper corresponding to each started object can be opened to the preset damper angle.

[0078] In the above embodiments, by controlling the fan not to start when the current start-up rate is less than the preset start-up rate, the fan will not generate noise, and the control box air valve corresponding to at least one already started object will be opened to the preset air valve angle, so that the smoke exhaust effect can be guaranteed without noise.

[0079] S205: Determine the current permissible noise range and the current fan speed based on the current fan speed range.

[0080] In one specific embodiment, the current fan speed may fall within the current fan speed range.

[0081] In one specific embodiment, the current permissible noise range may refer to the range of currently allowed fan noise. The current permissible noise range may include the maximum noise level within the current range. It is understood that fan noise within the aforementioned current permissible noise range will not adversely affect the user.

[0082] In one specific embodiment, the current wind turbine speed may refer to the speed at which the wind turbine needs to operate.

[0083] In one specific embodiment, the current allowable noise range can be obtained according to the following formula:

[0084] y max =k7·N2+a5

[0085] Among them, y max N1 represents the maximum noise level within the current range; N2 represents the maximum rotational speed within the current range; k7 and a5 are preset parameters. Specifically, k7 and a5 can be set according to actual application needs, and this disclosure does not impose any limitations.

[0086] In one specific embodiment, the current fan speed can be determined from the current fan speed range. Specifically, the minimum speed and the maximum speed in the current range can be averaged to obtain the current average speed, which can then be used as the current fan speed.

[0087] S207: Control the fan to run at the current fan speed and obtain the current fan noise information.

[0088] In one specific embodiment, after determining the current fan speed, the fan can be controlled by the main controller to operate at the current fan speed.

[0089] In one specific embodiment, the current fan noise information can characterize the noise level of the fan at the current moment. Specifically, when the fan is operating at the aforementioned current fan speed, noise can be collected using a noise sensor to obtain the current fan noise information.

[0090] S209: If the current fan noise information does not meet the current allowable noise range, adjust the smoke exhaust components based on the current fan speed range.

[0091] In one specific embodiment, the smoke exhaust assembly may include a fan, or the smoke exhaust assembly may include a fan and a control box damper corresponding to at least one opened object.

[0092] In one specific embodiment, if the current fan noise information is less than or equal to the maximum noise in the current range, it can be determined that the current fan noise information meets the current permissible noise range; if the current fan noise information is greater than the maximum noise in the current range, it can be determined that the current fan noise information does not meet the current permissible noise range.

[0093] In one specific embodiment, step S209 above may include:

[0094] If the current fan noise information does not meet the current allowable noise range, the current fan speed and the current fan speed range are compared to obtain the first comparison result.

[0095] If the first comparison result indicates that the current fan speed meets the current fan speed range, the current fan speed is reduced by a preset speed, and based on the reduced current fan speed, the process jumps to the above steps of controlling the fan to run at the current fan speed and obtaining the current fan noise information corresponding to the fan.

[0096] If the first comparison result indicates that the current fan speed does not meet the current fan speed range, the angle of the object air valve corresponding to each opened object is increased by a preset angle to reduce the current fan speed range. Based on the reduced current fan speed range, the process jumps to the steps of controlling the fan to run at the current fan speed and obtaining the current fan noise information corresponding to the fan.

[0097] In one specific embodiment, the first comparison result can be used to indicate whether the current wind turbine noise information meets the current permissible noise range.

[0098] In a specific embodiment, the preset speed can be set according to actual application needs. Specifically, the preset speed can range from 40 r / min to 60 r / min. Optionally, the preset speed can be 50 r / min. For example, taking a preset speed of 50 r / min as an example, if the first comparison result indicates that the current fan speed meets the current fan speed range, the current fan speed is reduced by 50 r / min to obtain the reduced current fan speed. Based on the reduced current fan speed, the process jumps to the step of controlling the fan to run at the current fan speed and obtaining the corresponding current fan noise information. Specifically, after jumping to the step of controlling the fan to run at the current fan speed and obtaining the corresponding current fan noise information, the fan can be controlled to run at the reduced current fan speed, and the reduced current fan noise information can be obtained again. Correspondingly, the re-obtained current noise information can be compared with the current allowable noise range. Through multiple comparisons, adjustments, and jumps, the current fan noise information can be kept within the current allowable noise range.

[0099] In a specific embodiment, the preset angle can be set according to actual application needs. Specifically, the preset angle can range from 1° to 3°. Optionally, the preset angle can be 2°. For example, taking a preset angle of 2° as an example, if the first comparison result indicates that the current fan speed does not meet the current fan speed range, the angle of the object valve corresponding to each opened object can be increased by 2°, that is, the control box valve corresponding to each opened object can be increased by 2°, reducing the current fan speed range. The reduced current fan speed range can be obtained, and based on the reduced current fan speed range, the process jumps to the step of controlling the fan to run at the current fan speed and obtaining the current fan noise information corresponding to the fan. Specifically, after jumping to the step of controlling the fan to run at the current fan speed and obtaining the current fan noise information corresponding to the fan, the current fan noise information after increasing the valve angle can be obtained again, and the current noise information obtained again can be compared with the current allowable noise range. This can be done through multiple comparisons, adjustments, and jumps until the current fan noise information meets the current allowable noise range.

[0100] In one specific embodiment, if the first comparison result indicates that the current fan speed does not meet the current fan speed range, the angle of the object valve corresponding to the highest floor among the at least one opened object can be obtained. If the object valve angle corresponding to the highest floor is 90°, the control box valves corresponding to the at least one opened object can be controlled to maintain the current object valve angle, and the fan can be controlled to maintain the current fan speed. Alternatively, if the first comparison result indicates that the current fan speed does not meet the current fan speed range, the angle of the object valve corresponding to at least one opened object can be obtained. If the object valve angles corresponding to the at least one opened object are all 90 degrees, the control box valves corresponding to the at least one opened object can be controlled to maintain the current object valve angle, and the fan can be controlled to maintain the current fan speed.

[0101] In one specific embodiment, the above method may further include:

[0102] If the current fan noise information meets the current allowable noise range, control the fan to operate at the current fan speed.

[0103] In the above embodiments, when the current fan noise information does not meet the current allowable noise range, a comparison is performed between the current fan speed and the current fan speed range to obtain a first comparison result. If the first comparison result indicates that the current fan speed meets the current fan speed range, the current fan speed is reduced by a preset speed. Based on the reduced current fan speed, the process jumps to the steps described above: controlling the fan to operate at the current fan speed and obtaining the corresponding current fan noise information. When the smoke extraction effect is within acceptable limits, fan noise can be reduced by decreasing the fan speed. Then, if the first comparison result indicates that the current fan speed does not meet the current allowable noise range... Under the condition of the fan speed range, the angle of the object air valve corresponding to each opened object is increased by a preset angle, the current fan speed range is reduced, and based on the reduced current fan speed range, the process jumps to the above steps of controlling the fan to run at the current fan speed and obtaining the current fan noise information. If the first comparison result indicates that the current fan speed does not meet the current fan speed range, the smoke extraction effect and noise reduction can be ensured by increasing the air valve angle and reducing the fan speed. Until the current fan noise information meets the current allowable noise range, the fan is controlled to run at the current fan speed, thereby achieving a balance between smoke extraction effect and noise reduction.

[0104] In one specific embodiment, prior to step S209, the method may further include:

[0105] Retrieve the floor information of at least one enabled object;

[0106] The object's floor information is compared with the preset range of high-rise floors to obtain a second comparison result.

[0107] If the floor information of the second comparison result does not belong to the preset high-rise floor range, the control fan runs at the current fan speed.

[0108] Accordingly, step S209 may also include:

[0109] If the floor information of the second comparison result indicates that there is floor information belonging to the preset high-rise floor range, and the current fan noise information does not meet the current allowable noise range, the smoke exhaust component is adjusted based on the current fan speed range.

[0110] In one specific embodiment, the object floor information corresponding to at least one activated object can characterize the floor to which each activated object belongs.

[0111] In one specific embodiment, the second comparison result can be used to indicate whether there is any floor information in the object floor information that belongs to the preset high-rise floor range.

[0112] In one specific embodiment, the preset range of high-rise floors can be set according to actual application needs. Specifically, the preset range of high-rise floors can be f. max / 2~f max ; where f max This refers to the information of the highest floor in a centralized smoke extraction system. For example, assume the highest floor information in the centralized smoke extraction system is f. max If the building has 20 floors, then the preset range of high-rise floors can be 10 to 20.

[0113] In one specific embodiment, if the floor information of the second comparison result indicates that none of them belong to the preset high-rise floor range, the fan is controlled to run at the current fan speed, and it is not necessary to determine whether the current fan noise information meets the current allowable noise range.

[0114] In the above embodiments, if the floor information of the objects indicated by the second comparison result does not belong to the preset high-rise floor range, it can be determined that at least one of the above-mentioned activated objects belongs to the low floors. The smoke extraction effect can be maintained by keeping the fan running at the current fan speed. It is understood that, due to the long public smoke duct, the noise from the fan located on the top floor has a relatively small impact on users on the lower floors.

[0115] In one specific embodiment, if the floor information of the second comparison result indicates that there is floor information belonging to the preset high-rise floor range, and the current fan noise information meets the current allowable noise range, the fan is controlled to run at the current fan speed.

[0116] In the above embodiments, in response to the smoke exhaust start command of the target object, the current start-up rate and the angle of the object damper corresponding to at least one opened object in the centralized smoke exhaust system are obtained. Based on the current start-up rate and the object damper angle, the current fan speed range is determined, which can determine the fan speed range that can achieve a good smoke exhaust effect. Then, combined with the current fan speed range, the current allowable noise range and the current fan speed are determined. The current fan speed is within the current fan speed range. Controlling the fan to run at the current fan speed can ensure the smoke exhaust effect of the centralized smoke exhaust system. Next, the current fan noise information corresponding to the fan is obtained. If the current fan noise information does not meet the current allowable noise range, the smoke exhaust components are adjusted based on the current fan speed range. The smoke exhaust components include the fan, or the fan and the control box damper corresponding to at least one opened object, thereby achieving noise reduction while ensuring the smoke exhaust effect, and thus achieving a balance between smoke exhaust effect and noise reduction.

[0117] Figure 3 This is a block diagram illustrating a fan control device in a centralized smoke exhaust system according to an exemplary embodiment. Figure 3 As shown, the device may include:

[0118] The first information acquisition module 310 can be used to obtain the current start-up rate and the angle of the air valve corresponding to at least one activated object in the centralized smoke exhaust system in response to the smoke exhaust start command of the target object.

[0120] The second information determination module 330 can be used to determine the current allowable noise range and the current fan speed based on the current fan speed range; the current fan speed belongs to the current fan speed range;

[0121] The first execution module 340 can be used to control the fan to run at the current fan speed and to obtain the current fan noise information corresponding to the fan.

[0122] The second execution module 350 can be used to adjust the smoke exhaust component based on the current fan speed range when the current fan noise information does not meet the current allowable noise range. The smoke exhaust component includes a fan, or a fan and a control box damper corresponding to at least one opened object.

[0123] In one specific embodiment, the second execution module 350 described above may include:

[0124] The first comparison module can be used to compare the current fan speed and the current fan speed range when the current fan noise information does not meet the current allowable noise range, and obtain the first comparison result.

[0125] The third execution module can be used to reduce the current fan speed to a preset speed when the first comparison result indicates that the current fan speed meets the current fan speed range, and based on the reduced current fan speed, jump to control the fan to run at the current fan speed, and obtain the current fan noise information corresponding to the fan.

[0126] The fourth execution module can be used to increase the angle of the object valve corresponding to each opened object by a preset angle when the first comparison result indicates that the current fan speed does not meet the current fan speed range, thereby reducing the current fan speed range.
