The default angle of plate is penetrated, afterwards, denoising Processing device 3 is set to sleep state, extraneous triggering is waited afterwards.For example, infrared receiver
Device 2 is received after the control signal of remote control transmission.At this moment, shown in Figure 6, this programme is implemented by the following method,
Denoising Processing device 3 reads infrared data, and when the infrared data is judged for 0, output driving data make the side clockwise of stepper motor 4
Forward further, afterwards, denoising Processing device 3 interrupts and returns；When judging the infrared data not for 0, output driving data make step
The counter clockwise direction of stepper motor 4 takes a step forward, and afterwards, denoising Processing device 3 interrupts return.
In this programme, motor 4 is preferably stepper motor 4.Stepper motor 4 is a kind of induction machine 4, by by electric pulse
Signal is changed into angular displacement or displacement of the lines is carried out controlled motor 4 and rotated.Direct current is become time sharing power supply by it using electronic circuit, by
Multiphase SECO electric current enables the normal work of stepper motor 4.Stepper motor 4 is mainly produced by the change of air-gap permeance
Raw electromagnetic torque, generally, the rotor of motor 4 is permanent magnet, and when electric current flows through stator winding, stator winding produces a vector
Magnetic field, magnetic field meeting rotor driven is rotated, and makes a pair of magnetic field direction of rotor consistent with the magnetic direction of stator.Work as stator
Vector Magnetic Field rotate to an angle, rotor is also with the magnetic field rotating certain angle.When the direction for needing to change stepper motor 4
When, by changing the order that winding is powered, motor 4 will be inverted.
In the case of the external load of stepper motor 4 is non-overloading, the rotating speed of motor 4, the position for stopping are solely dependent upon pulse
The frequency of signal, and do not affected by load change, in this case, stepper motor 4 is easy to control, and stable.This
Sample, during carrying out practically, after stepper motor 4 receives a pulse signal, will turn according to direction set in advance
A fixed angle is moved, the angle of the fixation is referred to as " step angle ".In the scheme of the present embodiment, denoising Processing device 3 passes through
The order that winding set in advance is powered controlling step direction, so as to reach the purpose of control direction；Meanwhile, arteries and veins can be passed through
The displacement that number i.e. stepping step number carrys out the rotation of controlled motor 4 is rushed, so as to reach the purpose being accurately positioned.
