Description

Technical Field

[0002] An air handling unit is composed of multiple components or multiple devices. Through the rotation of its own fan, it drives the indoor and outdoor air to exchange heat with the heat exchange coil inside the unit. It can also filter impurities in the air to control the outlet air temperature and air volume to maintain indoor temperature, humidity and air cleanliness.

[0003] The air volume control valve (abbreviated as air valve) that comes with the air handling unit can be purchased and installed by the user. Although the size and interface of the air valve are standard, different models of air valves have different air valve openings and preset speeds. When the user or installation and maintenance personnel generate instructions to debug the air valve through the central control panel of the air handling unit, the central control panel can only send debugging instructions to the air valve in a one-way manner. There is a lack of debugging interaction process, which makes it impossible for the debugging personnel to accurately judge the debugging status. Summary of the Invention

[0054] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementation methods.

Therefore, the various orders in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a necessary order, unless otherwise specified that a certain order must be followed.

[0055] In the description of this application, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0056] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0057] The damper of the air handling unit is an electric damper, which includes at least a gas pipe, a swing blade arranged in the gas pipe, and a motor arranged outside the gas pipe, wherein the output shaft of the motor penetrates the gas pipe and serves as the rotating shaft of the swing blade; for example, when the gas pipe is a cylindrical pipe, the output shaft of the motor extends within the gas pipe along the diameter of the gas pipe, so that the circular swing blade rotates along the diameter of the gas pipe to achieve the opening control of the gas pipe; when the gas pipe is a square cylindrical pipe, the output shaft of the motor penetrates perpendicularly to the center line of the inner wall of one side of the gas pipe, so that the rectangular swing blade rotates along the center axis of the gas pipe to achieve the opening control of the gas pipe. The above-mentioned electric damper has a single swing blade structure, or the electric damper has a multi-swing blade structure but the description focuses on the swing blade located in the middle.

[0058] Air handling units (AHUs) are typically equipped with a central control panel, which allows the user to configure and test the operating status of various AHU components. Damper valves are removable and replaceable within the AHU, so they must be debugged after installation. Currently, debugging damper valves through the central control panel is a one-way process, making it difficult for the operator to accurately determine the valve's status.

[0059] Based on this, an embodiment of the present application provides a damper debugging method, a debugging device and an air handling unit of an air handling unit. The ranging module can be linked with the air handling unit, and a first space is set on the central control screen of the air handling unit, and a second space is set on the swing blade of the damper. The ranging module can be set in the first space, or removed from the first space and placed in the second space for damper debugging. When the ranging module is placed in the second space, the air handling unit controls the swing blade of the damper to rotate for at least one cycle, and receives the distance data sent by the ranging module. The air handling unit automatically determines the rotation duration and opening of the swing blade within one cycle based on the distance data received during the debugging process, and obtains the corresponding relationship between the rotation duration and opening of the damper. In the above manner, the ranging module provides feedback data for the debugging process, helping the debugging personnel to debug the damper, so as to accurately judge the debugging status.

[0060] The following describes the air valve debugging method, debugging device and air handling unit of the air handling unit with reference to the accompanying drawings:

[0061] Reference Figure 1 As shown, Figure 1 This is a flow chart of the overall method for debugging a damper 100 in an air handling unit according to an embodiment of the present application. The air handling unit includes a central control panel 300, which has a first space for accommodating a distance measuring module 200. The swing blade 110 of the damper 100 is provided with a second space for accommodating the distance measuring module 200. The distance measuring module 200 is used to measure the distance from its own position to the inner wall 130 of the damper 100. The method for debugging the damper 100 includes, but is not limited to, the following steps:

[0062] Step S110, receiving distance data fed back by the distance measuring module 200 when it is set in the second space, the distance data being a plurality of distances measured by the distance measuring module 200 during at least one cycle of the swing leaf rotation;

[0063] Step S120 , determining the rotation duration and opening degree of the pendulum blade 110 within one cycle according to the distance data, and obtaining a corresponding relationship between the rotation duration and the opening degree.

[0064] The air valve 100 of the embodiment of the present application can be an air valve 100 with a single pendulum blade 110 structure. The ranging module 200 can be set on the front or back of the pendulum blade 110, or the ranging module 200 can be set on both the front and back. The ranging module 200 can use different types of distance measurement sensors, such as ultrasonic radar modules, laser radar modules, millimeter wave radar modules, etc. The ranging module 200 of the present application is described by taking the laser radar module as an example. Obviously, the hardware basis of the present application is to set the ranging module 200 on the surface of the pendulum blade 110, and the ranging module 200 establishes a communication connection with the air handling unit, and the air handling unit is connected to the motor 120 of the air valve 100 for control. The software basis of the present application, namely the above-mentioned air valve 100 debugging method, is to control the rotation of the pendulum blade 110 for at least one cycle when the distance measuring module 200 is set on the surface of the pendulum blade 110. During the rotation process, the distance measuring module 200 continuously measures the distance between its own position and the inner wall 130 of the air valve 100. By receiving the distance data fed back by the distance measuring module 200, the air handling unit obtains the rotation time and actual opening of the pendulum blade 110 according to the distance data, and then determines the corresponding relationship between the rotation time and the opening, and displays the relevant measurement data on the central control screen 300.

[0065] Therefore, the embodiment of the present application sets a distance measuring module 200 on the swing blade 110 and realizes the visualization of the debugging parameters based on the feedback data of the distance measuring module 200. Compared with the current solution in which the air handling unit can only send instructions to the air valve 100 for debugging in one direction, or compared with the current solution in which the air handling unit can only obtain the data feedback from the motor 120 of the air valve 100 for debugging, the present application can track the position of the swing blade 110 through the distance measuring module 200, and calculate the correspondence between the above-mentioned rotation time and opening degree based on the position of the swing blade 110, providing more detailed and accurate data for the debugging personnel, so that the debugging personnel can judge the debugging status of the air valve 100. The debugging personnel can then adjust the control parameters of the air valve 100 and optimize the working parameters of the air handling unit. It is especially suitable for the debugging of the newly installed air handling unit or the maintenance debugging after the replacement of the air valve 100.

[0066] Reference Figure 3 and Figure 4 As shown, the ranging module 200 can be designed to be detachable. The ranging module 200 can be detachably arranged on the surface of the pendulum blade 110, that is, the ranging module 200 can be detachably accommodated in the second space, so that the position of the ranging module 200 can be easily adjusted, and the ranging module 200 can be reused on other air valves 100 or other pendulum blades 110 of the air valve 100. The volume of the ranging module 200 can be designed to be relatively small, such as a miniature intelligent laser ranging module, which will hardly affect the rotation of the pendulum blade 110. After debugging is completed, the ranging module 200 can be removed and returned to the first space of the central control screen 300.

[0067] Reference Figure 5 As shown, based on the above-mentioned detachable ranging module 200, a receiving groove 310 for accommodating the ranging module 200 can be set in the shell of the central control screen 300. The receiving groove 310 is the first space mentioned above. After debugging is completed, the debugging personnel can remove the ranging module 200 from the pendulum blade 110 and place it in the receiving groove 310. When debugging is required next time, take it out of the receiving groove 310 and install it on the pendulum blade 110. The groove body of the receiving groove 310 can be designed to match the shape of the ranging module 200, such as using a card slot form, or using spring clip fixation, etc., which are not listed here one by one.

[0068] The surface of the swing blade 110 of the air valve 100 is provided with two distance measuring modules 200, the two distance measuring modules 200 are respectively provided on the front and back sides of the swing blade 110, and the two distance measuring modules 200 are symmetrically provided along the rotation axis of the swing blade 110. Figure 6 As shown, Figure 6 The front view of the swing blade 110 of the air valve 100 is shown. One of the distance measuring modules 200 is set at the upper position of the front side of the swing blade 110, and another distance measuring module 200 is set at the lower position of the back side of the swing blade 110 (indicated by a dotted box in the figure). Figure 7 and Figure 8 As shown, Figure 7 and Figure 8 This is a top view of the swing blade 110 of the air valve 100. A distance measuring module 200 is respectively set on the front and back sides of the swing blade 110, and the two distance measuring modules 200 are symmetrically arranged along the rotation axis of the swing blade 110. In this way, the distance data measured by the two distance measuring modules 200 at the same time are basically the same, which facilitates calculation based on the distance data of the two distance measuring modules 200.

[0069] It can be understood that in order to ensure that the positions of the two ranging modules 200 are symmetrical along the rotation axis of the pendulum blade 110, labels can be set on the front and back of the pendulum blade 110. The label is the aforementioned second space, for example, printed with an indicator pattern such as a square pattern, and the label on the front and the label on the back are symmetrical along the rotation axis of the pendulum blade 110. In this way, the debugging personnel can set the ranging module 200 according to the label to meet the symmetry requirements.

[0070] It is worth noting that when the ranging module 200 is set in the first space and the ranging module 200 is connected to the air handling unit for communication, the ranging module 200 can measure the distance between the debugger or other users and the central control screen 300. Based on this distance, the air handling unit can sense that the user is close to the central control screen 300, and actively wake up the central control screen 300 to facilitate user operation. If the central control screen 300 supports the user voice control function, when the central control screen 300 receives external voice, the voice recognition threshold is set according to the distance measured by the ranging module 200. For example, when the user is closer to the central control screen 300, there is less interference from environmental noise, so the voice recognition threshold is set lower to collect a wider range of voices to facilitate recognition of the user's voice commands; when the user is farther away from the central control screen 300, the voice recognition threshold is set higher to exclude some environmental noise, focus on recognizing the voice of the main sound source, and reduce the false recognition rate.

[0071] Reference Figure 2 As shown, in some embodiments, after obtaining the corresponding relationship between the rotation duration and the opening degree, the method further includes:

[0072] Step S130, receiving a target opening instruction for the air valve 100, and determining a target rotation time according to the target opening instruction and the corresponding relationship;

[0073] Step S140 , while controlling the rotation of the pendulum blade 110 according to the target rotation duration, the actual opening of the pendulum blade 110 is displayed through the central control screen 300 .

[0074] Specifically, the target opening is specified by the commissioning personnel in the target opening instruction. The air handling unit controls the motor 120 of the damper 100 according to the target opening and determines the target rotation duration based on the correspondence in step S120 and the target opening. Ideally, the motor 120 controls the rotation of the swing vane 110 according to the target opening, and the swing vane 110 eventually rotates to the target opening. However, due to the different set parameters of different dampers 100, whether the target opening can be achieved and how long it takes to achieve the target opening vary. Therefore, the commissioning process primarily determines the performance of the damper 100, including the damper 100 speed, rotation duration, and actual opening. The motor 120 of the air valve 100 controls the rotation of the pendulum 110 according to the instruction corresponding to the target opening (actually converted into the control instruction of the rotation angle), and the distance measurement module 200 on the surface of the pendulum 110 periodically returns distance data to the air handling unit. Due to the rotation of the pendulum 110, the distance from the distance measurement module 200 to the inner wall 130 of the air valve 100 is constantly changing. Therefore, during the entire rotation process of the pendulum 110, the air handling unit receives multiple distance values ​​to form the distance data of this debugging. Therefore, the distance data shows a certain change pattern over time. According to the distance data, the rotation time of the pendulum 110 can be determined, and the actual opening of the pendulum 110 after the motor 120 controls the pendulum 110 to rotate to the target opening can also be obtained by calculation. Then, the speed of the air valve 100 can be calculated based on the rotation time and the actual opening, and the various data in the above debugging process are displayed on the central control screen 300. The debugging personnel can judge the debugging status through the display content of the central control screen 300.

[0075] It is understandable that the number of the distance measuring modules 200 can be set according to actual needs. For example, two distance measuring modules 200 are set, and the two distance measuring modules 200 are symmetrically arranged on the front and back sides of the swing blade 110 (such as Figure 5 As shown), during one rotation of the swing blade 110 controlled by the motor 120, the speed, rotation duration and actual opening of the air valve 100 can be calculated based on the obtained distance data; for example, only one distance measurement module 200 (such as Figure 2 As shown, the motor 120 controls the pendulum 110 to rotate twice. During one rotation, the distance measuring module 200 is set on the front side of the pendulum 110, and during the other rotation, the distance measuring module 200 is set on the back side of the pendulum 110. The speed, rotation duration, and actual opening of the damper 100 are calculated based on the distance data obtained from the two rotations. Of course, when only one distance measuring module 200 is provided, if some hardware data of the damper 100 is known, the motor 120 controls the pendulum 110 to rotate once, and the speed, rotation duration, and actual opening of the damper 100 can also be calculated based on the obtained distance data. The specific calculation method of the parameters of the above debugging process will be described in detail below.

[0076] Reference Figure 9 As shown, in some embodiments, determining the rotation duration of the swing blade 110 according to the distance data in the above step S120 includes:

[0077] Step S210, during the rotation of the pendulum blade 110, recording the distance data sent by at least one distance measurement module 200 and the time corresponding to the distance data;

[0078] Step S220, determining the first moment when the pendulum blade 110 starts to rotate and the second moment when the pendulum blade 110 reaches the maximum opening according to the variation pattern of the distance data;

[0079] Step S230 , determining the duration of one rotation cycle of the pendulum blade 110 according to the first moment and the second moment.

[0080] Generally speaking, the ranging line (detection direction) of the ranging module 200 is perpendicular to the surface of the pendulum blade 110; according to the structure of the air valve 100, when the opening degree is 0 (equivalent to a rotation angle of 0 degrees), the pendulum blade 110 closes the ventilation duct, and the distance measured by the ranging module 200 is the largest (there is no obstacle in front of the ranging module 200 or the obstacle is very far away); when the opening degree is 100 (equivalent to a rotation angle of 90 degrees), the pendulum blade 110 completely opens the ventilation duct, and the distance measured by the ranging module 200 is the smallest (the pendulum blade 110 is parallel to the inner wall 130 of the air valve 100).

[0081] When only one distance measuring module 200 is provided on the surface of the pendulum blade 110, during the rotation of the pendulum blade 110, the air handling unit obtains the distance data sent by the distance measuring module 200, and can derive the variation pattern of the distance data. According to the variation pattern, it can be determined when the pendulum blade 110 starts to rotate and when the pendulum blade 110 stops rotating, which is equivalent to selecting the distance data corresponding to when the pendulum blade 110 starts to rotate and the distance data corresponding to when the pendulum blade 110 stops rotating. Since the air handling unit can record the time corresponding to the currently received distance data when receiving the distance data, it is possible to derive the first time of the distance data corresponding to when the pendulum blade 110 starts to rotate and the second time of the distance data corresponding to when the pendulum blade 110 stops rotating, and then the rotation duration can be derived based on the first time and the second time, for example, the time difference obtained by directly subtracting the first time from the second time is used as the rotation duration.

[0082] In the case where two ranging modules 200 are provided on the surface of the pendulum blade 110, during the rotation of the pendulum blade 110, the air handling unit obtains the distance data sent by at least one ranging module 200. If only the distance data sent by one of the ranging modules 200 is obtained, the process of deriving the rotation duration can refer to the previous paragraph and will not be repeated here. If the distance data sent by the two ranging modules 200 are obtained simultaneously, the corresponding rotation durations of the two ranging modules 200 can be obtained by referring to the method in the previous paragraph, and then the two rotation durations can be compared or data processed, for example, the average of the two rotation durations can be taken as the final rotation duration.

[0083] Reference Figure 10 As shown, in some embodiments, determining the first moment when the pendulum blade 110 starts to rotate and the second moment corresponding to when the pendulum blade 110 reaches the maximum opening according to the variation pattern of the distance data in the above step S220 includes:

[0084] Step S310, selecting the moment corresponding to the maximum value in the distance data as the first moment when the pendulum blade 110 starts to rotate;

[0085] Step S320 , selecting the moment corresponding to the minimum value in the distance data as the second moment corresponding to the rotation of the swing blade 110 to reach the maximum opening.

[0086] As previously known, the change in distance data decreases as the opening of the pendulum 110 increases. Ideally, the change pattern of the distance data over time is smooth. In this case, the moment corresponding to the maximum value of the distance data is directly selected as the first moment, and the moment corresponding to the minimum value of the distance data is selected as the second moment. However, in reality, the pendulum 110 may vibrate during rotation, resulting in a non-smooth change pattern in the distance data. Moreover, after the pendulum 110 rotates to its maximum opening, a sudden stop can also cause fluctuations in the distance data. To reduce errors, these distances can be curve-fitted to obtain a change curve of the distance data. The maximum and minimum values ​​on the change curve are then selected, and the first and second moments are determined based on the maximum and minimum values ​​of the change curve. To reduce errors, only several distances before and after the pendulum 110 begins to rotate and several distances before and after the pendulum 110 ends its rotation can be considered. Before and after the pendulum 110 begins to rotate, the distance gradually decreases from a stable value. The moment when the stable value begins to decrease is the first moment. Before and after the pendulum 110 ends its rotation, the distance gradually decreases to a stable value. The moment when it decreases to a stable value is the second moment.

[0087] Reference Figure 11As shown, in some embodiments, the two ranging modules 200 are respectively a first ranging module 210 and a second ranging module 220, and the first ranging module 210 and the second ranging module 220 are symmetrically arranged along the rotation axis of the pendulum 110; the above step S220 determines the opening degree of the pendulum 110 within one cycle based on the distance data, including:

[0088] Step S410, during the rotation of the pendulum blade 110, recording the first distance data sent by the first distance measurement module 210 and the second distance data sent by the second distance measurement module 220;

[0089] Step S420, determining a target first distance corresponding to the maximum opening of the pendulum blade 110 from the first distance data, and determining a target second distance corresponding to the maximum opening of the pendulum blade 110 from the second distance data;

[0090] Step S430 : determining the maximum opening of the swing blade 110 within one cycle according to the target first distance and / or the target second distance.

[0091] In the case where the air valve 100 has a single pendulum blade 110 structure, or the air valve 100 has a multi-pendulum blade 110 structure but two distance measuring modules 200 are set for the front and back sides of the pendulum blade 110 located in the middle, the actual rotation angle of the pendulum blade 110 can be determined by the first distance data of the first distance measuring module 210 and the second distance data of the second distance measuring module 220, and then the actual opening can be determined according to the actual rotation angle. Specifically, after the motor 120 controls the rotation of the pendulum blade 110 according to the target opening, the pendulum blade 110 is at the maximum opening during the debugging process. According to the method of step S320 above, the target first distance corresponding to the maximum opening of the pendulum blade 110 of the first distance measuring module 210 and the target second distance corresponding to the maximum opening of the pendulum blade 110 of the second distance measuring module 220 can be determined. By comparing the target first inspection distance and the target second distance, it can be determined whether the rotation angle of the pendulum blade 110 reaches 90 degrees. The actual rotation of the pendulum blade 110 can also be calculated based on geometric calculations. Angle. The actual opening can be calculated based on the corresponding relationship between the actual rotation angle and the opening. For example, according to the formula of angle = opening / maximum opening * 90 * balance coefficient, the actual opening can be calculated by substituting the actual rotation angle. The maximum opening in the formula is usually 100, and the parameter 90 corresponds to a rotation of 90 degrees. If the maximum rotation angle calibrated by the air valve 100 is 90 degrees, the balance coefficient is 100%. If the maximum rotation angle calibrated by the air valve 100 is not 90 degrees, the debugging personnel can adjust the balance coefficient so that 90*balance coefficient is equal to the calibrated maximum rotation angle.

[0092] In some embodiments, when the two distance measuring modules 200 are respectively disposed on the front and back sides of the swing blade 110 , the above step S430 determines the maximum opening of the swing blade 110 within one cycle according to the target first distance and the target second distance, including:

[0093] If the target first distance and / or the target second distance are equal to the target length, the current opening is determined to be the maximum opening of the air valve 100 , and the target length is the distance between the rotation axis of the swing blade 110 and the inner wall 130 ;

[0094] If the target first distance and / or the target second distance are not equal to the target length, the current opening is determined according to the target length, the target first distance and / or the target second distance.

[0095] Reference Figure 6 The figure shows a front view of a damper 100 with a single-blade structure, comprising a first distance measuring module 210 and a second distance measuring module 220. When the actual rotation angle of the damper 100 is 90 degrees, the target first distance from the first distance measuring module 210 to the inner wall 130 of the damper 100 and the target second distance from the second distance measuring module 220 to the inner wall 130 of the damper 100 are both equal to the target length, i.e., the distance between the rotation axis of the damper 110 and the inner wall 130 of the damper 100. If a damper 100 with multiple blades 110 is used, the target length for the middle blade 110 is also the distance between the rotation axis of the blade 110 and the inner wall 130 of the damper 100.

[0096] Therefore, based on the above target length, if the air handling unit determines that the target first distance and the target second distance are both equal to the target length, it means that the rotation angle of the swing blade 110 is 90 degrees after the rotation is completed (refer to Figure 7 As shown), the actual opening at this time is the maximum opening of the air valve 100, that is, the opening is 100%. If the air handling unit determines that the target first distance and the target second distance are not equal to the target length, it means that the swing blade 110 has rotated. After the swing blade 110 rotates, the rotation angle is not 90 degrees, but may be 80 degrees (refer to Figure 8 (as shown), the corresponding actual opening is not 100%. The actual opening can be determined based on the target length, the target first distance, and / or the target second distance. Assuming the target first distance and the target second distance are equal, the difference between the target length and the target first distance is used as one of the right-angled legs of a right triangle, and the target length is used as the hypotenuse. The angle corresponding to the cosine value is calculated, and this angle is the difference between the actual rotation angle and 90 degrees (for example, if the actual rotation angle is 80 degrees, the angle is 10 degrees).

[0097] It is worth noting that the above calculation process is also applicable to the case where the pendulum blade 110 is only equipped with one ranging module 200. Since the calculation process only needs to use the first distance of the target or the second distance of the target (because ideally the first distance data and the second distance data are equal, but using the first distance data and the second distance data at the same time can improve the accuracy, and the first distance data and the second distance data can be collected separately in two debugging processes, or can be collected simultaneously in one debugging process), the pendulum blade 110 is only equipped with one ranging module 200. The angle corresponding to the cosine value can also be calculated to obtain the actual rotation angle.

[0098] It can be understood that the target length is a preset value; alternatively, the target length is determined based on the distance between the two ranging modules 200, both of which are arranged near the edge of the pendulum 110, and at least one of the two ranging modules 200 is also used to measure the distance from its own position to the other ranging module 200.

[0099] Among them, the preset target length can be input by the user; when the ranging module 200 has the function of measuring the distance from its own position to another ranging module 200, the ranging module 200 can be set close to the edge of the pendulum 110, so that the distance between the two ranging modules 200 can be measured. This distance can be used as the target length by adjusting the coefficient. The coefficient is related to the setting position of the ranging module 200. If the two ranging modules 200 are set according to the diagonal of the square pendulum 110, the coefficient can be less than 1. If the two ranging modules 200 are set according to the diagonal of the circular pendulum 110 but are not completely close to the edge of the circular pendulum 110, the coefficient can be greater than 1, and so on.

[0100] In some embodiments, when the two distance measuring modules 200 are disposed on the same surface of the swing blade 110 , the above step S430 determines the actual opening according to the target first distance and the target second distance, including:

[0101] If the target first distance and the target second distance are equal, the current opening is determined to be the maximum opening of the air valve 100;

[0102] If the target first distance and the target second distance are not equal, the current opening is determined according to the difference between the target first distance and the target second distance and the target length, where the target length is the distance between the rotation axis of the swing blade 110 and the inner wall 130 .

[0103] Reference Figure 12The figure shows a front view of the swing blade 110 of the damper 100 with a single swing blade 110 structure, which has a first distance measuring module 210 and a second distance measuring module 220. When the actual rotation angle of the swing blade 110 is 90 degrees, the target first distance from the first distance measuring module 210 to the inner wall 130 of the damper 100 and the target second distance from the second distance measuring module 220 to the inner wall 130 of the damper 100 are equal (as shown in FIG. Figure 13 ), which is equal to the distance between the rotation axis of the swing blade 110 and the inner wall 130 of the damper 100. If a damper 100 with multiple swing blades 110 is used, then for the middle swing blade 110, the target length is also the distance between the rotation axis of the swing blade 110 and the inner wall 130 of the damper 100. If the target first distance and the target second distance are not equal (e.g. Figure 14 As shown), it indicates that the actual rotation angle of the pendulum blade 110 has not reached 90 degrees, for example, it may be 80 degrees. At this time, the actual opening is determined according to the target length, the target first distance and the target second distance. Assuming that the target first distance and the target second distance are equal, half of the difference between the target length and the target first distance is used as a right angle side of the right triangle, and the target length is used as the hypotenuse of the right triangle. The angle corresponding to the cosine value is calculated, and the angle is the difference between the actual rotation angle and 90 degrees (for example, if the above-mentioned actual rotation angle is 80 degrees, then the angle is 10 degrees). It is worth noting that the above-mentioned calculation process is not applicable to the case where the pendulum blade 110 is only provided with one ranging module 200.

[0104] Reference Figure 15 As shown, in some embodiments, the step S110 of receiving the target opening instruction of the air valve 100 includes:

[0105] Step S510: receiving the target opening input by the commissioning personnel through the central control panel 300, and also receiving at least one of the number of the air valve 100, the initial opening, and the set speed of the air valve 100 input by the commissioning personnel through the central control panel 300;

[0106] In step S520 , the target opening is displayed on the central control screen 300 , and at least one of the number of the air valve 100 , the initial opening, and the set speed of the air valve 100 is displayed on the central control screen 300 .

[0107] The central control screen 300 provides a human-computer interaction interface, and various debugging parameters can be displayed in the human-computer interaction interface. For example, in the embodiment of the present application, a display box or display position for parameters such as the target opening, the number of the air valve 100, the initial opening, and the set speed of the air valve 100 is provided. During the debugging process, the debugger inputs parameters such as the target opening, the number of the air valve 100, the initial opening, and the set speed of the air valve 100, and these debugging parameters are displayed in the corresponding display box or display position; in addition to being able to display the data entered by the debugger, the human-computer interaction interface can also display various data of the debugging results, including the speed of the air valve 100, the rotation time, and the actual opening, etc., providing interactive information for the debugger and improving the convenience of debugging.

[0108] In summary, in the embodiment of the present application, a distance measuring module 200 is provided on the surface of the swing blade 110 of the air valve 100. The distance measuring module 200 can be linked with the air handling unit. When the debugging personnel debug the air valve 100, the distance measuring module 200 is received to measure the distance between the swing blade 110 of the air valve 100 and the inner wall 130 of the air valve 100. The air handling unit automatically determines the rotation time and actual opening of the swing blade 110 according to the distance data received during the debugging process, and then automatically determines the rotation time and actual opening of the swing blade 110 according to the rotation time and actual opening. The air valve 100 speed is determined based on the actual opening, and the air valve 100 speed, rotation time and actual opening are displayed on the central control screen 300. The debugging personnel can also input debugging data through the central control screen 300 to realize the visualization of the debugging process. In the above manner, the distance measurement module 200 provides feedback data for the debugging process, that is, distance data. The air handling unit provides debugging parameters such as the air valve 100 speed, rotation time and actual opening on the central control screen 300 according to the distance data. The debugging personnel can directly know the debugging results and thus can accurately judge the debugging status.

[0109] The following describes in detail the method for debugging the air valve 100 of the air handling unit of the present application through two specific examples.

[0110] Example 1

[0111] Reference Figure 6 As shown, Figure 6 FIG1 is a front view of the swing blade 110 of the air valve 100. The swing blade 110 is circular. A distance measuring module 200 is provided on the front and back of the swing blade 110. One distance measuring module 200 is provided at the upper position of the front of the swing blade 110, and another distance measuring module 200 (indicated by a dotted box) is provided at the lower position of the back of the swing blade 110. Figure 7 and Figure 8 As shown, Figure 7 and Figure 8 It is a top view of the swing blade 110 of the air valve 100 , and the two distance measurement modules 200 are symmetrically arranged along the rotation axis of the swing blade 110 .

[0112] The ranging module 200 on the surface of the pendulum blade 110 can be removed, and two accommodating slots 310 for accommodating the ranging module 200 are provided near the central control screen 300 of the air handling unit; when the ranging module 200 is needed, the ranging module 200 is taken out from the accommodating slot 310 and fixed on the surface of the pendulum blade 110. After using the ranging module 200, the ranging module 200 is removed and placed in the accommodating slot 310.

[0113] After the distance measuring module 200 is installed on the surface of the pendulum blade 110, the distance measuring module 200 is wirelessly connected to the air handling unit to transmit distance data; the debugging personnel set the target opening of the air valve 100 on the debugging interface of the central control screen 300 and start the timing. The air handling unit controls the rotation of the pendulum blade 110 according to the target opening, and finally stops after the pendulum blade 110 rotates a certain angle.

[0114] The target length is determined based on the distance data transmitted back during the rotation of the pendulum blade 110. The target length is the distance between the rotation axis of the pendulum blade 110 and the inner wall 130 of the damper 100. If the distance measured by the two distance measuring modules 200 from the pendulum blade 110 to the inner wall 130 of the damper 100 is equal to the target length, the rotation angle of the damper 100 is 90 degrees and the damper 100 is in a normal state. If the distance measured by the two distance measuring modules 200 from the pendulum blade 110 to the inner wall 130 of the damper 100 is not equal to the target length, the rotation angle of the damper 100 is not 90 degrees. By converting the distance using the relevant geometric calculation formula, the actual rotation angle of the damper 100 and the actual opening degree can be obtained, and the user is notified that the damper 100 is in an abnormal state.

[0115] The central control panel 300 stops timing, calculates the speed of the air valve 100 according to the relevant formula, and updates the relevant parameters of the air valve 100 in the air valve 100 management system of the central control panel 300. The relevant calculation formula may include:

[0116] (1) Angle = opening / maximum opening * 90 * balance coefficient

[0117] (2) Power-on duration = |actual opening - initial opening| / maximum opening * damper 100 speed

[0118] In the above two formulas, the balance coefficient is related to the set maximum rotation angle of the air valve 100, the initial opening is 0, the maximum opening is 100%, and the power-on time represents the rotation time.

[0119] The actual rotation angle, rotation time and actual opening of the air valve 100 are obtained by calculation, and the parameters such as the air valve 100 number, balance coefficient, initial opening, target opening, power-on time, etc. are displayed through the human-computer interaction interface of the air valve 100 management system of the central control screen 300. The above two calculation formulas can also be displayed, as well as the parameters of the current debugging process, including the air valve 100 speed, rotation time and actual opening, etc.

[0120] Example 2

[0121] Reference Figure 12 As shown, Figure 12 The front view of the swing blade 110 of the air valve 100 is shown. The swing blade 110 is circular. Two distance measuring modules 200 are set on the front of the swing blade 110. One of the distance measuring modules 200 is set at the upper position of the front of the swing blade 110, and the other distance measuring module 200 is set at the lower position of the front of the swing blade 110. Figure 13 and Figure 14 As shown, Figure 13 and Figure 14 It is a front view of the swing blade 110 of the air valve 100 , and the two distance measurement modules 200 are symmetrically arranged along the rotation axis of the swing blade 110 .

[0122] The ranging module 200 on the surface of the pendulum blade 110 can be removed, and two accommodating slots 310 for accommodating the ranging module 200 are provided near the central control screen 300 of the air handling unit; when the ranging module 200 is needed, the ranging module 200 is taken out from the accommodating slot 310 and fixed on the surface of the pendulum blade 110. After using the ranging module 200, the ranging module 200 is removed and placed in the accommodating slot 310.

[0123] After the distance measuring module 200 is installed on the surface of the pendulum blade 110, the distance measuring module 200 is wirelessly connected to the air handling unit to transmit distance data; the debugging personnel set the target opening of the air valve 100 on the debugging interface of the central control screen 300 and start the timing. The air handling unit controls the rotation of the pendulum blade 110 according to the target opening, and finally stops after the pendulum blade 110 rotates a certain angle.

[0124] The target length is determined based on the distance data transmitted back during the rotation of the pendulum blade 110. The target length is the distance between the rotation axis of the pendulum blade 110 and the inner wall 130 of the damper 100. If the two distance measuring modules 200 measure the distances from the pendulum blade 110 to the inner wall 130 of the damper 100 to be equal, the rotation angle of the damper 100 is 90 degrees and the damper 100 is in a normal state. If the two distance measuring modules 200 measure the distances from the pendulum blade 110 to the inner wall 130 of the damper 100 to be unequal, the rotation angle of the damper 100 is not 90 degrees. By converting the distances using relevant geometric calculation formulas, the actual rotation angle of the damper 100 and the actual opening degree can be determined, and the user is alerted that the damper 100 is in an abnormal state.

[0125] The central control panel 300 stops timing, calculates the speed of the air valve 100 according to the relevant formula, and updates the relevant parameters of the air valve 100 in the air valve 100 management system of the central control panel 300. The relevant calculation formula may include:

[0126] (1) Angle = opening / maximum opening * 90 * balance coefficient

[0127] (2) Power-on duration = |actual opening - initial opening| / maximum opening * damper 100 speed

[0128] In the above two formulas, the balance coefficient is related to the set maximum rotation angle of the air valve 100, the initial opening is 0, the maximum opening is 100%, and the power-on time represents the rotation time.

[0129] The actual rotation angle, rotation time and actual opening of the air valve 100 are obtained by calculation, and the parameters such as the air valve 100 number, balance coefficient, initial opening, target opening, power-on time, etc. are displayed through the human-computer interaction interface of the air valve 100 management system of the central control screen 300. The above two calculation formulas can also be displayed, as well as the parameters of the current debugging process, including the air valve 100 speed, rotation time and actual opening, etc.
