Speed operation.
Specifically, when permanent magnet 2 selects permanent magnet pieces and Hall sensor 1 is mounted on the surface of permanent magnet pieces, In
Permanent magnet pieces are in 3 rotation process of machine shaft, only permanent magnet pieces and when 1 face of Hall sensor, Hall sensor 1 to
MCU controller conveys forward voltage, and when remaining situation, i.e. permanent magnet pieces be not with 1 face of Hall sensor, Hall sensor 1 is all
Voltage signal is not sent to MCU controller.Within the period of the every rotation one week of motor 4, MCU controller obtains Hall in the period
The voltage that sensor 1 transmits, as shown in Fig. 2, obtaining PWM duty cycle a and frequency corresponding to the currently practical tachometer value of motor 4 in turn
Rate f, to obtain the real-time speed of clothes airing machine, MCU controller further compares the real-time tachometer value of motor 4 and setting value V
Adjust the revolving speed of motor, when specific way of contrast is that setting motor reaches setting speed value V, Hall sensor is sent to
The PWM duty cycle of MCU controller is A, frequency F.By determining the size of real-time frequency f and setpoint frequency F, if f is less than
F then determines that the real-time speed v of clothes airing machine is less than setting speed value V；If f is greater than F, then determine that the real-time speed v of clothes airing machine is big
In setting speed value V；In the case where f is equal with F, if duty ratio a is less than setting duty ratio A in real time, then clothes airing machine is determined
The rate of climb be less than decrease speed, if a be greater than A, then determine clothes airing machine the rate of climb be greater than decrease speed, if a etc.
In A, then determine that the rate of climb of clothes airing machine is equal to decrease speed.Finally according to the comparing result of real-time tachometer value and setting value V,
The output voltage of metal-oxide-semiconductor is controlled to adjust the revolving speed of motor by drive module, until clothes hanger is risen or fallen with constant
Speed operation.
It is selected when permanent magnet 2 and has permanent magnet ring jaggy, the outer ring of the permanent magnet ring is the pole N, and inner ring is the pole S, and suddenly
When your sensor 1 is mounted on the surface of permanent magnet ring, in permanent magnet ring in 3 rotation process of machine shaft, only permanent magnetism
When the complete part of iron hoop is with 1 face of Hall sensor, Hall sensor 1 can convey forward voltage, remaining feelings to MCU controller
When condition, the i.e. barbed portion of permanent magnet ring and 1 face of Hall sensor, Hall sensor 1 does not send voltage to MCU controller
Signal.Within the period of the every rotation one week of motor 4, MCU controller obtains the voltage that Hall sensor 1 transmits in the period, such as
Shown in Fig. 3, and then PWM duty cycle a and frequency f corresponding to the currently practical tachometer value of motor 4 is obtained, to obtain clothes airing machine
Real-time speed, MCU controller further compare the real-time tachometer value of motor 4 and setting value to adjust the revolving speed of motor, specifically
Way of contrast be setting motor when reaching setting speed value V, the PWM duty cycle that Hall sensor sends MCU controller to is
A, frequency F.By determining the size of real-time frequency f and setpoint frequency F, if f is less than F, then the real-time speed of clothes airing machine is determined
It spends v and is less than setting speed value V；If f is greater than F, then determine that the real-time speed v of clothes airing machine is greater than setting speed value V；In f and F phase

Degree is equal to decrease speed.Finally according to the comparing result of real-time tachometer value and setting value V, metal-oxide-semiconductor is controlled by drive module
Output voltage adjusts the revolving speed of motor, until clothes hanger rises or falls speed operation with constant.
When permanent magnet 2 selects complete permanent magnet ring, the left-half of the permanent magnet ring is the pole N, and right half part is the pole S,
And Hall sensor 1 is when being mounted on the surface of permanent magnet ring, in permanent magnet ring in 3 rotation process of machine shaft, only
When the left-half and 1 face of Hall sensor of permanent magnet ring, Hall sensor 1 can convey forward voltage to MCU controller,
When remaining situation, the i.e. right half part of permanent magnet ring and 1 face of Hall sensor, Hall sensor 1 then sends to MCU controller negative
To voltage.Within the period of the every rotation one week of motor 4, MCU controller obtains the voltage that Hall sensor 1 transmits in the period,
As shown in figure 4, PWM duty cycle a and frequency f corresponding to the currently practical tachometer value of motor 4 is obtained in turn, to obtain clothes airing machine
Real-time speed, MCU controller further compares the real-time tachometer value of motor 4 and setting value to adjust the revolving speed of motor, tool
When the way of contrast of body is that setting motor reaches setting speed value V, Hall sensor sends the PWM duty cycle of MCU controller to
For A, frequency F.By determining the size of real-time frequency f and setpoint frequency F, if f is less than F, then the real-time of clothes airing machine is determined
Speed v is less than setting speed value V；If f is greater than F, then determine that the real-time speed v of clothes airing machine is greater than setting speed value V；In f and F
In the case where equal, if duty ratio a is less than setting duty ratio A in real time, then determine that the rate of climb of clothes airing machine is less than lower reduction of speed
Degree then determines that the rate of climb of clothes airing machine is greater than decrease speed, if a is equal to A, then determines the upper of clothes airing machine if a is greater than A
Lifting speed is equal to decrease speed.Finally according to the comparing result of real-time tachometer value and setting value V, MOS is controlled by drive module
The output voltage of pipe adjusts the revolving speed of motor, until clothes hanger rises or falls speed operation with constant.
Further, this regulation device is additionally provided with remote control reception module and power module, wherein remote control reception module
Signal output port is connect with the signal input port of MCU controller, for receiving the control instruction of clothes airing machine remote controler, in turn
The instruction is transferred to MCU controller to handle.Power module is connect with the power input port of MCU controller, for for
Regulation device power supply.
Real-time monitoring and the clothing that dries in the air can be adjusted using the lifting speed regulation device on clothes airing machine provided by the present embodiment
The speed of service of machine keeps constant the speed that rises or falls of clothes airing machine, clothes airing machine is avoided to occur Caton in the process of running
The phenomenon that, while the noise generated in operation is reduced, it prevents system resonance from causing clothes airing machine connection loosing, there is preferable market
Application prospect.
Embodiment 2
