Description
本發明係關於一種風扇控制方法;特別是關於一種吊扇啟動角位鎖定方法。 The present invention relates to a fan control method; and more particularly to a ceiling fan activation angle locking method.
習知吊扇(ceiling fan)可裝設於室內天花板,使用者可透過開關控制吊扇供電狀態,使馬達帶動扇葉之葉片產生氣流,以利室內空氣循環或散熱等用途。 The conventional ceiling fan can be installed on the indoor ceiling. The user can control the power supply state of the ceiling fan through the switch, so that the motor drives the blades of the fan blade to generate airflow for the purpose of indoor air circulation or heat dissipation.
以習知直流吊扇為例,通常可由通用控制器控制馬達轉動,隨馬達裝設的扇葉大小不同,馬達所需輸出的轉動慣量及扭力等參數亦須改變,否則吊扇啟動時將會產生抖動或逆轉角度過大等異狀。為了改善此情況,該通用控制器須先經過學習(learning)過程,用以產生適當電流啟動吊扇。 Taking the conventional DC ceiling fan as an example, the motor can usually be controlled by a general-purpose controller. The parameters such as the moment of inertia and the torque required by the motor must be changed depending on the size of the fan blades installed in the motor. Otherwise, the ceiling fan will generate jitter when it is started. Or reverse the angle is too large and other abnormalities. In order to improve this situation, the universal controller must first undergo a learning process to generate the appropriate current to start the ceiling fan.
值得注意的是,習知直流吊扇停止轉動後,馬達之磁極可能位於未知的位置,為了避免啟動(或起轉)失敗,啟動時須先進行〝啟動找角過程〞,如:以較大電流驅動馬達,待找到適當角位後,以便驅使風扇產生氣流。惟,該啟動找角過程常會產生令人不適的雜音、異音或逆轉角度過大,故而無法用於要求風扇安靜運轉的場所。 It is worth noting that after the conventional DC ceiling fan stops rotating, the magnetic pole of the motor may be located at an unknown position. In order to avoid the failure of starting (or starting), the start-up process must be started first, such as: with a large current. Drive the motor to find the proper angle to drive the fan to create airflow. However, the start of the angle finding process often produces uncomfortable noise, abnormal sounds or excessive reversal angles, so it cannot be used in places where the fan is required to operate quietly.
有鑑於此,有必要改善上述先前技術的缺點,以符合實際需求,提升其實用性。 In view of this, it is necessary to improve the shortcomings of the prior art described above to meet practical needs and improve its practicability.

請參閱第3圖所示,其係本發明之吊扇啟動角位鎖定方法實施例之運作流程圖。請一併參閱第1圖所示,其中,該方法實施例可實現於上述控制邏輯,惟不以此為限,以便應用於控制上述吊扇1之馬達11運轉的控制器12,該控制器12可經由該驅動器13致動(actuating)該馬達11。 Please refer to FIG. 3, which is a flow chart of the operation of the embodiment of the ceiling fan locking angle locking method of the present invention. Please refer to FIG. 1 together, wherein the method embodiment can be implemented in the above control logic, but not limited thereto, so as to be applied to the controller 12 for controlling the operation of the motor 11 of the ceiling fan 1, the controller 12 The motor 11 can be actuated via the driver 13.
舉例而言,該控制器12可先進行一初始化程序,如:設定轉速訊號、驅動電流及其他預設的參數等,供該控制器12經由該驅動器13致動該馬達11,使該馬達11具有一閒置模式(idle mode)Md及一驅風模式(ventilation mode)Mv。其中,該閒置模式Md係待命進入該驅風模式Mv,該驅風模式Mv可由該控制器12控制該驅動器13持續供電至該馬達11,使該馬達11持續運轉帶動扇葉14以產生氣流,該方法之步驟可包含:若該馬達11處於該閒置模式Md,該控制器12及該驅動器13係接收電力待命操控該馬達11,該控制器12可偵測該預定角位是否位於該預定角度,如:該控制器12可經由該驅動器13輪流送電至該馬達11之不同線圈,使該馬達11轉動,經由該馬達11內部的線圈電性特徵(如:電流或反電動勢等)隨時間的變化量,可以得知該變化量與馬達轉動位置的對應關係(如:轉動特性曲線),用以偵測該馬達11之預定角位是否位於該預 定角度(如:可查表或依圓周與轉角比例換算等),若判斷為「是」,該控制器12可控制該驅動器13輸出訊號(如:可供該馬達11維持鎖止狀態的訊號),用以鎖定該馬達11;若判斷為「否」,表示該預定角位與預定角度之間具有差距,該控制器12可控制該驅動器13輸出訊號(如:可供該馬達11旋轉一角度的訊號),依據該差距致動該馬達11,使該馬達11的預定角位轉至該預定角度,用以鎖定該馬達11。藉此,當該吊扇1之馬達11閒置時,可由該控制器12控制該馬達11鎖定於預定位置,待需由該吊扇1產生氣流時,即可直接啟動該吊扇1運轉,無需進行習知〝啟動找角過程〞,以避免產生令人不適的雜音、異音或逆轉角度過大等。 For example, the controller 12 may first perform an initialization process, such as setting a speed signal, a driving current, and other preset parameters, etc., for the controller 12 to actuate the motor 11 via the driver 13, and the motor 11 is enabled. There is an idle mode M d and a ventilation mode M v . The idle mode M d is standby to enter the wind drive mode M v , and the drive mode M v can be controlled by the controller 12 to continuously supply power to the motor 11 to enable the motor 11 to continuously drive the fan blade 14 to The step of the method may include: if the motor 11 is in the idle mode M d , the controller 12 and the driver 13 receive power to control the motor 11 , and the controller 12 can detect whether the predetermined angular position is Located at the predetermined angle, for example, the controller 12 can alternately transmit power to the different coils of the motor 11 via the driver 13, and rotate the motor 11 via the electrical characteristics of the coil inside the motor 11 (eg, current or back electromotive force, etc.) Depending on the amount of change in time, the corresponding relationship between the amount of change and the rotational position of the motor (eg, the rotational characteristic curve) can be known to detect whether the predetermined angular position of the motor 11 is at the predetermined angle (eg, a checklist) Or according to the circumference and the corner ratio conversion, etc., if the determination is YES, the controller 12 can control the output signal of the driver 13 (for example, a signal for the motor 11 to maintain the locked state) for locking the motor 11 If If the determination is "No", it means that there is a gap between the predetermined angular position and the predetermined angle, and the controller 12 can control the output signal of the driver 13 (for example, a signal for the motor 11 to rotate by an angle), and actuate according to the gap. The motor 11 rotates the predetermined angular position of the motor 11 to the predetermined angle for locking the motor 11. Thereby, when the motor 11 of the ceiling fan 1 is idle, the controller 11 can be controlled by the controller 12 to be locked in a predetermined position, and when the airflow is generated by the ceiling fan 1, the ceiling fan 1 can be directly started, without conventional knowledge. 〝 Start the angling process to avoid unpleasant noises, abnormal sounds or excessive reversal angles.
此外,受控於該控制器12的馬達11停止產生氣流時,該馬達11及扇葉14仍可能由其它外力帶動,如:該扇葉14可由轉動慣量帶動而慣性運轉,或該扇葉14可受風吹動而由風力帶動等。此時,該控制器12亦可逐漸控制該旋轉中的馬達11之預定角位停至該預定角度,舉例說明如後。 In addition, when the motor 11 controlled by the controller 12 stops generating airflow, the motor 11 and the blade 14 may still be driven by other external forces, such as: the blade 14 may be inertially driven by the moment of inertia, or the blade 14 It can be driven by the wind and so on by the wind. At this time, the controller 12 can also gradually control the predetermined angular position of the rotating motor 11 to stop at the predetermined angle, as exemplified below.
舉例而言,如第1及3圖所示,該控制器12可經由該驅動器13致動該馬達11,使該馬達11具有上述驅風模式Mv及一慣轉模式(inertia mode)Mr,該驅風模式Mv係如上所述,若該馬達11供電中斷,則該馬達11進入該慣轉模式Mr。該方法之步驟可包含:若該馬達11處於該驅風模式Mv,該控制器12可偵測該預定角位;若該馬達11處於該慣轉模式Mr,該控制器12可控制該驅動器13輸出訊號對該馬達11施加一減速力矩,如:控制該馬達11之定子線圈形成封閉迴路產生煞車力等,使該馬達11之預定角位逐漸停至該預定角度,用以鎖定該馬達11。藉此,於該馬達轉動趨緩時,可由該控制器12控制該馬達11鎖定於預定位置,等到需由該吊扇1產生氣流時,即可直接啟動該吊扇1運轉,無需進行習知〝啟動找角過程〞,以避免產生令人不適的雜音、異音或逆轉角度過大等。 For example, as shown in FIGS. 1 and 3, the controller 12 may actuate the motor 11 via the driver 13, so that the driving motor 11 having the above-described air model M v and a rotation mode inertia (inertia mode) M r The drive mode M v is as described above, and if the power supply to the motor 11 is interrupted, the motor 11 enters the normal rotation mode M r . The method may include: if the motor 11 is in the air blowing mode M v , the controller 12 can detect the predetermined angular position; if the motor 11 is in the inertia mode M r , the controller 12 can control the The output signal of the driver 13 applies a deceleration torque to the motor 11, for example, controlling the stator coil of the motor 11 to form a closed loop to generate a braking force, etc., so that the predetermined angular position of the motor 11 is gradually stopped to the predetermined angle for locking the motor. 11. Thereby, when the motor rotates slowly, the controller 11 can be controlled by the controller 12 to be locked in a predetermined position, and when the airflow needs to be generated by the ceiling fan 1, the ceiling fan 1 can be directly started to operate without the need for a conventional start. Look for the angle process to avoid unpleasant noises, abnormal sounds or excessive reversal angles.
在此例中,若該馬達11處於該慣轉模式Mr或閒置模式Md,該控制器12可判斷該馬達11的轉速是否大於一轉速限值(rotation speed threshold),如:該控制器12可依據該馬達11內部的線圈電性特徵隨時間的變化量估算轉速,作為判斷該馬達11的轉速是否大於該轉速限值之依據,若判斷為「是」,該控制器12可控制該驅動器13輸出訊號,對該馬達11施加該減速力矩,直到該馬達11的轉速不大於該轉速限值為止,若判斷為「否」,該控制器12可控制該馬達11的預定角位停至該預定角度;其中,該轉速限值之範圍可介於2至10r.p.m.,可用於避免該馬達11之轉速過高,以便確保該馬達11的預定角位可準確的停至該預定角度,惟不以此為限。 In this example, if the motor 11 is in the inertia mode M r or the idle mode M d , the controller 12 can determine whether the rotational speed of the motor 11 is greater than a rotation speed threshold, such as: 12 can estimate the rotational speed according to the change amount of the electrical characteristics of the coil inside the motor 11 as a basis for determining whether the rotational speed of the motor 11 is greater than the rotational speed limit. If the determination is YES, the controller 12 can control the The driver 13 outputs a signal, and the deceleration torque is applied to the motor 11 until the rotation speed of the motor 11 is not greater than the rotation speed limit. If the determination is No, the controller 12 can control the predetermined angular position of the motor 11 to stop. The predetermined angle; wherein the speed limit may range from 2 to 10 rpm, which may be used to prevent the rotation speed of the motor 11 from being too high, so as to ensure that the predetermined angular position of the motor 11 can be accurately stopped to the predetermined angle. However, it is not limited to this.
藉此,本發明上述實施例於該吊扇1閒置、受風吹動或慣性旋轉時,可由該控制器12自動偵測該馬達11的預定角位,以便進一步得知該預定角位與預定角度之間的差距,並依據該差距致動該馬達11,使該馬達11之預定角位鎖定於該預定角度,等到該吊扇1之馬達11需啟動時,即可直接啟動該吊扇1持續順暢運轉用於產生氣流,無需再進行習知〝啟動找角過程〞,以避免產生令人不適的雜音、異音或逆轉角度過大等,可以達到「啟動後運轉順暢」、「降低啟動音量」及「避免啟動失敗」等功效,可應用於需要風扇安靜運轉的場所,可進一步增加吊扇使用需求量。 Therefore, in the above embodiment of the present invention, when the ceiling fan 1 is idle, blown by the wind or rotated by inertia, the controller 12 can automatically detect the predetermined angular position of the motor 11 to further know the predetermined angular position and the predetermined angle. The gap between the motor 11 is actuated according to the gap, and the predetermined angular position of the motor 11 is locked at the predetermined angle. When the motor 11 of the ceiling fan 1 needs to be activated, the ceiling fan 1 can be directly started for smooth operation. In order to generate airflow, there is no need to carry out the conventional process of starting the angle finding process to avoid uncomfortable noise, abnormal sound or excessive reversal angle, etc., which can achieve "smooth running after starting", "lower starting volume" and "avoid The function of starting failure can be applied to places where the fan needs to be quietly operated, and the demand for ceiling fan can be further increased.
