Letter module sends invalid cleaning instruction, first serial communication module feedback information to air-conditioning master controller, air-conditioning master control control
Device processed continues to accumulate on the basis of t1 at runtime, and when t1 is more than or equal to T1, air-conditioning master controller is to the first string
Mouth communication module sends effective cleaning instruction, and first serial communication module transmits the signal to motor driver.Meanwhile need
The run time t1 that will build up on is reset, and re-starts the accumulation of fan operation time.
Preferably, the motor driver performs following steps：
After the completion of step 21, motor driver power-up initializing, motor driver judges whether to receive draught fan impeller clean
Instruction, if so, starting draught fan impeller clean operation and accumulating the clean operation time, goes to step 22, if not, repeat step 21 is grasped
Make；
Step 22, judge whether impeller clean run accumulated time exceedes threshold value T3, if so, draught fan impeller cleaning instruction is removed,
Cleaning Cumulative Elapsed Time is reset, while is back to step 21；If not, enter step 23；
Step 23, control draught fan impeller reversion；
Step 24, judge whether draught fan impeller reversing time exceedes threshold value T2, if so, 25 are then entered step, if not, continuing to control
Draught fan impeller reversion processed；
Step 25, control draught fan impeller rotate forward；
Step 26, judge that draught fan impeller rotates forward whether the time exceedes threshold value T4, if so, 27 are then entered step, if not, continuing to control
Draught fan impeller processed rotates forward；
Step 27, carry out accumulation calculating to the draught fan impeller clean run time, returns to step 22, repeats after the completion of calculating
Aforesaid operations.
Preferably, the step 23, step 24, step 25, step 26 are implemented as follows：
Step 23, give birth to the stator flux vector for being angled α according to motor control algorithms module control motor drive module；
Step 24, judge whether angle exceedes threshold value T2 for the stator flux vector excitation time of α, if so, then entering step 25；
If not, continue the raw stator flux vector for being angled α；
Step 25, give birth to the stator flux vector for being angled β according to motor control algorithms module control motor drive module；
Step 26, judge whether angle exceedes threshold value T4 for the stator flux vector excitation time of β, if so, then entering step 27；
If not, continue the raw stator flux vector for being angled β.
As shown in figure 3, the α is 0 °, the β is 90 °.
Specifically, what motor 6 was made of threephase stator winding 1 and rotor 2, by be passed through into threephase stator winding 1 by
The electric current of sinusoidal rule change, can produce the magnetic flux vector with certain orientation, the magnetic flux vector and rotor flux vector 5 are mutual
Effect can produce 6 rotating electromagnetic torque of motor, and in the present invention, switch generation stator winding 1 by Rapid Circulation 0 ° is determined
Sub- magnetic flux vector 3 and 90 ° of stator flux vectors 4 so that the quick rotation back and forth between 0 ~ 90 ° of motor 6, so that wind turbine can be realized
The effect that impeller 7 is shaken.
After the completion of motor driver power-up initializing, the number of master controller transmission is received by second serial communication module
According to, judge whether to receive the instruction of draught fan impeller automatically cleaning, be back to and rejudge if not receiving, if having been received by,
Judge whether 7 automatically cleaning of draught fan impeller operation accumulated time exceedes given threshold, if exceeding threshold value, removing draught fan impeller is from clear
Clean instruction and clearing 7 self-operating accumulated time of draught fan impeller, if not less than threshold value, 6 control algolithm module of motor control motor 6
Drive module generates 0 ° of stator flux vector 3, judges that excitation is held time and whether exceedes preset time threshold, if not exceeded, then
0 ° of stator flux vector 3 is continuously generated, to produce electromagnetic torque by stator magnetic flux and the interaction of 2 magnetic flux of rotor, by rotor 2
Rotation is extremely consistent with 0 ° of 3 direction of stator flux vector, if excitation time exceedes predetermined threshold value, by 6 control algolithm module of motor
Control 6 drive module of motor to give birth to stator flux vector 4 in 90 °, judge that excitation is held time and whether exceed preset time threshold, if
Not less than, then be continuously generated 90 ° of stator flux vectors 4, so as to by stator magnetic flux and 2 magnetic flux of rotor interaction produce electromagnetism turn
Square, rotor 2 is rotated to consistent with 90 ° of 4 directions of stator flux vector, if excitation time exceedes predetermined threshold value, accumulates wind turbine
7 automatically cleaning run time of impeller, returns again to judging whether 7 automatically cleaning run time of draught fan impeller exceedes threshold value, finally repeats
Flow is controlled as described above in execution.It is reasonable that the excitation time of the stator flux vector of generation is set, you can realizes 6 rotor 2 of motor 0
Quickly carry out back rotation between ~ 90 °, the effect of the shake of draught fan impeller 7 is also just can reach, so as to fulfill 7 automatically cleaning of draught fan impeller.
Need exist for explanation is 0 ~ 90 ° of as one preferable number range of the embodiment, however it is not limited to 0 ~ 90 °,
Can be with 0-120 ° or 0-150 °.
Preferably, the T1 is 1 day ~ 7 days, and the T2 is 50ms ~ 500ms, and the T3 is 5s ~ 10s, and the T4 is 50ms
~500ms。
Specifically, T1 can be the arbitrary value in 1 day ~ 7 days, can be set according to different environment.For example, working as makes
It is larger with the dust of environment, time T1 can be set shorter, such as 1-3 days or so, when the ambient dust used is smaller, then may be used
To set time T1 longer, such as 4-7 days；Time T2 and T4 can be the arbitrary value in 50ms ~ 500ms, which can root
Set according to ambient dust size, dust is big, and setting value can be near minimum value, and dust is small, and setting value can be in maximum
Near value；T3 can be any one numerical value in 5s ~ 10s, and equally, the big environment of dust can set a larger number
Value, carries out dust the cleaning of long period, reaches cleaning thoroughly purpose, the small environment of dust can set one it is less
Numerical value, carries out dust the cleaning of short period, you can reaches clean purpose, avoids wasting electric power resource.
