Processing circuit 1218 is illustrated as including AC input detector 1224, DC input detectors 1226 and controller 1232.AC input detector 1224 and DC input detectors 1226 can be configured to receive control from input connection 802 clockwise Signal 1234, the input connection 802 clockwise can be the components of input connection 520.Processing circuit 1218 can be configured to Determine that control signal 1234 is AC voltage signals or DC voltage signal.Processing circuit 1218 may be in response to determine control signal 1234 are AC voltage signals and operate motor 1210 using AC motor control technologies.However, processing circuit 1218 can be rung It should be DC voltage signal and operate motor 1210 using DC motor control technologies in determining control signal 1234.For example, If being AC voltage signals by inputting the control signal 1234 that connection 802 provides clockwise, AC input detector 1224 can quilt It is configured to generate AC detection signals 1228, on the contrary, DC input detectors 1226 can not generate DC detection signals 1230.If by The control signal 1234 that input connection 802 provides clockwise is DC voltage signal, then DC input detectors 1226 can be configured to It generates DC and detects signal 1230, and AC input detector 1224 can not generate AC detection signals 1228.If input clockwise Connection 802 neither provides AC voltage signals and does not provide DC voltage signal again, then AC input detector 1224 and DC input detectors 1226 can not generate detection signal.

Referring still to Figure 12, processing circuit 1218 is illustrated as including controller 1232, which is configured to It receives AC detection signals 1228 from AC input detector 1224 and receives DC from DC input detectors 1226 and detect signal 1230. In some embodiments, once receiving, AC detects signal 1228 or DC detection signals 1230, controller 1232 are configured to generate Motor control signal 1236, the Motor control signal 1236 can control rotating speed or the position of motor 1210.For example, such as Fruit controller 1232 receives AC detection signals 1228, then controller 1232 can send Motor control signal 1236 to motor 1210 by driving device 510 to be moved to its maximum rotation position.

On the contrary, if controller 1232 receives DC detection signals 1230, controller 1232 can utilize DC to detect signal 1230 value generates Motor control signal 1236, and the Motor control signal 1236 makes motor 1210 be detected based on DC Driving device 510 is moved to some position by the value of signal 1230.For example, DC detection signals 1230 can be D/C voltage.It is based on The value of D/C voltage, controller 1232 can determine suitable position that can be proportional to D/C voltage.It is ordered by DC detection signals 1230 Position can be some between minimum rotation position, maximum rotation position or minimum rotation position and maximum rotation position among Position.In other embodiments, Motor control signal can be generated by providing the peripheral control unit of AC or DC voltage signal 1236。

If controller 1232 does not receive AC detection signals 1228 or DC detection signals 1230, controller 1232 can will be electronic Machine control signal 1236 is sent to motor 1210, this makes motor 1210 that driving device 510 is moved to minimum rotation position.Such as Fruit motor 1210 is powered (such as control source by being received at input 804 counterclockwise), and motor 1210 can make drive Dynamic device 510 drives to minimum rotation position (for example, as common in ON/OFF control).However, if motor 1210 are not powered (such as inputted at 804 or CW inputs 802 in CCW and be not received by input voltage), then motor 1210 can Stop at its current location (for example, as common in being controlled in floating-point).

Referring now to Figure 13, circuit diagram 1300 in accordance with some embodiments is shown, which includes clockwise Input connection 802, counterclockwise input connection 804, AC input detector 1224 and DC input detectors 1226.AC input detector Both 1224 and DC input detectors 1226 are illustrated as connecing from 802 (indicating with " gray line " in fig. 13) of input connection clockwise Receive input.It is generated according to the state of input signal clockwise (such as AC signals, DC signals etc.) or AC input detector 1224 AC detects signal 1228 or DC input detectors 1226 generate DC and detect signal 1230.

In addition Figure 13 depicts the voltage (V to correction_{_Rectified}) the input clockwise the connection 802 and inverse time made contributions Both needle input connections 804.In some embodiments, corrected voltage can be used as the source of the available power of motor 1210. Although clockwise both input connection 802 and input connection 804 counterclockwise contribute the voltage of correction, it is arranged suitable The diode 1240 (being illustrated as diode D2) in current path between hour hands input connection and counterclockwise input connection is true Only input signal clockwise has been protected to be assessed by AC input detector 1224 and DC input detectors 1226.In other words, two pole Pipe 1240 stops CCW input signals arrival input detector, but allows CW inputs and CCW to input the two and made to the voltage of correction Contribution.Circuit in AC input detector 1224 includes optically coupled circuit U2, resistor R6, R7 and R8, diode D1 and electricity Container C4.Circuit in DC input detectors 1226 includes operational amplifier U1, resistor R1, R2, R3, R4, R5 and R8, voltage Source V2 and capacitor C1, C2 and C3.Capacitor C5 and variable resistance I1 are connected in parallel between diode D3 and earth point, two poles Pipe D3 is coupled to red line.
