Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for controlling the rotational speed of an air conditioner motor, where the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer-executable instructions, and where a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that illustrated herein.
Fig. 1 is a flowchart of a method of controlling a rotation speed of a motor of an air conditioner according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, receiving a feedback signal of an air conditioner motor, wherein the feedback signal carries the motor feedback pulse number of the air conditioner motor;
step S104, determining the current motor rotating speed of the air conditioner motor based on the motor feedback pulse number;
and step S106, if the current motor rotating speed is detected to be not equal to the target motor rotating speed, controlling the air conditioner motor to adjust the current output pulse duty ratio, and continuously and circularly acquiring the current motor rotating speed of the air conditioner motor until the current motor rotating speed is detected to be equal to the target motor rotating speed.
In the embodiment of the invention, a feedback signal of an air conditioner motor is received, wherein the feedback signal carries the motor feedback pulse number of the air conditioner motor; determining the current motor rotating speed of the air conditioner motor based on the motor feedback pulse number; if the current motor rotating speed is not equal to the target motor rotating speed, the air conditioner motor is controlled to adjust the current output pulse duty ratio, the current motor rotating speed of the air conditioner motor is continuously obtained in a circulating mode until the current motor rotating speed is equal to the target motor rotating speed, the purposes of stably adjusting the rotating speed of the air conditioner motor and improving the operation stability of the air conditioner motor are achieved, the technical effects of reducing noise caused by fluctuation of the rotating speed of the air conditioner motor and improving the performance index of an air conditioning system are achieved, and the technical problems that noise is caused by too fast adjustment of the rotating speed of the air conditioner motor and the performance index of the air conditioning system is influenced by too slow adjustment of the rotating speed of the motor in the prior art are solved.
Optionally, the air conditioner motor is a motor of an air conditioner internal unit, and an execution main body of the method for controlling the rotating speed of the air conditioner motor provided by the embodiment of the application is a main controller.
In this embodiment, as shown in fig. 2, in the optional closed-loop control system for an air conditioning motor, a main controller receives a feedback signal sent by the air conditioning motor, and determines whether a current motor rotation speed is close to a target motor rotation speed based on a feedback pulse number carried in the feedback signal and sent by the air conditioning motor, if the current motor rotation speed is less than the target motor rotation speed, a PWM pulse duty ratio output by the air conditioning motor is appropriately increased (as in process 1), and the main controller determines whether the current motor rotation speed is close to the target motor rotation speed through the received motor feedback pulse number, and if the current motor rotation speed is greater than the target motor rotation speed, the main controller appropriately decreases or reduces the PWM pulse duty ratio output by the air conditioning motor (as in process 2). And on the contrary, the PWM pulse duty ratio output by the air conditioner motor is properly increased, the rotating speed of the motor is judged in a circulating mode, and the rotating speed of the air conditioner motor is adjusted in real time until the current rotating speed of the motor is detected to be equal to the target rotating speed of the motor.
According to the control method provided by the embodiment of the application, the control method for adjusting the rotating speed of the air conditioner motor by combining quick adjustment and slow adjustment is adopted, so that the air conditioner motor can stably run under specific conditions, the noise generated in the running of the internal unit is reduced, the running stability of the air conditioner motor can be improved, the noise problem caused by the rotating speed fluctuation of the air conditioner motor is reduced, and the comfort of the air conditioner product is improved.
In an optional embodiment, before receiving the feedback signal of the air conditioner motor, the method further includes:
step S202, acquiring a current operation mode of an air conditioner indoor unit;
step S204, determining whether the current operation mode is a target operation mode, wherein the target operation mode includes at least one of the following: an automatic cleaning mode, a defrosting operation mode, a testing operation mode and a fixed frequency operation mode;
step S206, if the judgment result is yes, controlling the air conditioner motor to adjust the current motor rotating speed to the target motor rotating speed based on the target operation mode; and if the judgment result is negative, executing the step of receiving the feedback signal of the air conditioner motor.
As shown in fig. 3, the main controller first determines whether a current operation mode of the air conditioner internal unit is a target operation mode, for example, an automatic cleaning mode, a defrosting operation mode, a test operation mode, a fixed frequency operation mode, and the like. If the current operation mode of the air conditioner indoor unit is the target operation mode, the motor rotating speed is not adjusted slowly, the air conditioner motor is controlled to adjust the current motor rotating speed to the target motor rotating speed based on the target operation mode, the motor rotating speed is guaranteed to be adjusted to the target rotating speed according to different working conditions, for example, the air conditioner indoor unit judges whether the current motor rotating speed is close to the target motor rotating speed, and if the current motor rotating speed is not close to the target motor rotating speed, the main controller controls the air conditioner motor rotating speed to be adjusted to the target motor rotating speed in a mode of changing the duty ratio.
Still as shown in fig. 3, if the air conditioner internal unit does not execute the target operation mode, it is determined whether the current motor speed is higher than the target motor speed, and if the current motor speed is lower than the target motor speed set by the user (the target motor speed is a motor speed value set by the user, and the value of the target motor speed may be determined according to the actual air conditioner test or the user experience), the main controller calculates whether the current motor speed is close to the target motor speed according to the motor feedback pulse number carried in the received motor feedback signal.
If the current motor rotating speed is not close to the target motor rotating speed, the PWM pulse duty ratio is adjusted rapidly, the current motor rotating speed is enabled to tend to the target motor rotating speed, the current motor rotating speed of an air conditioner indoor unit is judged in real time in the mode, if the current motor rotating speed is higher than the target rotating speed, the PWM pulse duty ratio output of the motor is reduced, if the current motor rotating speed is lower than the target motor rotating speed, the PWM pulse duty ratio output is increased, and the motor rotating speed slow adjustment action is not. The motor rotating speed is low, the fluctuation of the motor rotating speed is small, the duty ratio output is increased or reduced a little, the change of the motor rotating speed is relatively small, and the method is suitable for a rapid motor rotating speed adjusting mode, so that the current motor rotating speed can be rapidly adjusted to the target motor rotating speed.
In an alternative embodiment, controlling the air conditioner motor to adjust the pulse duty ratio of the current output includes:
step S302, detecting a wind sweeping working mode of an air deflector of an air conditioner indoor unit;
step S304, if the wind sweeping working mode is a full-sweeping working mode, controlling the air conditioner motor to adjust the pulse duty ratio at a preset adjusting rate;
and step S306, if the wind sweeping working mode is a non-full sweeping working mode, controlling the air conditioner motor to adjust the current output pulse duty ratio based on the preset deviation value, the current motor rotating speed and the target motor rotating speed.
In an optional embodiment of the application, if the air deflector air sweeping operation mode of the air conditioner indoor unit is a non-full-sweeping operation mode, when the current motor rotation speed of the motor is lower than the target motor rotation speed, the PWM pulse duty cycle output of the motor is increased, so that the current motor rotation speed slowly approaches the target motor rotation speed, if the current motor rotation speed is close to the target motor rotation speed, the PWM pulse duty cycle output is not adjusted by the air conditioner indoor unit, after the main controller adjusts the current motor rotation speed to tend to be equal to the target motor rotation speed, the PWM pulse duty cycle output is changed by a small amplitude, the motor rotation speed fluctuation is approximately within a deviation of plus or minus 5 revolutions of the target value, the motor rotation speed fluctuation range is relatively.
In an optional embodiment of the present application, if the air deflector of the air conditioner internal unit is in the full-sweep mode, the air outlet and the air direction are changed, and a fast adjustment manner is used, which easily causes an over-high or over-low rotation speed, so that the relationship between the current motor rotation speed and the target value rotation speed and the predetermined deviation value is increased and judged, and the air conditioner motor is controlled to adjust the current output pulse duty ratio.
In the embodiment of the application, when the air deflector of the air conditioner is detected to move, the size of the air outlet is changed, the rotating speed change of the motor is influenced, the main controller judges whether the current rotating speed of the motor is equal to a target rotating speed value or not according to a motor feedback signal, if the current rotating speed of the motor is higher than or lower than the target value, the main controller continuously adjusts the current rotating speed of the motor towards the target rotating speed of the motor, and the rotating speed fluctuation is easily large due to the excessively fast or excessively slow adjusting speed. In order to solve the problems, judgment of whether the air deflector moves is added, if the feedback signal of the motor changes greatly, the main controller judges that the rotating speed of the motor is higher than a target value plus a deviation value (or lower than the target value plus the deviation value), and then the rotating speed of the motor is regulated, and the rotating speed of the motor is not regulated within the range of the target value plus or minus the deviation value.
In an alternative embodiment, controlling the air conditioning motor to adjust the pulse duty ratio of the current output based on the predetermined deviation value, the current motor speed, and the target motor speed includes:
step S402, if the current motor speed is higher than the target motor speed plus the preset deviation value, controlling the air conditioner motor to reduce the current output pulse duty ratio;
step S404, if the current motor speed is lower than the target motor speed minus the preset deviation value, controlling the air-conditioning motor to increase the currently output pulse duty ratio;
step S406, if the current motor speed is higher than the target motor speed minus the predetermined deviation value, and the current motor speed is lower than the target motor speed plus the predetermined deviation value, controlling the air conditioning motor without changing the currently output pulse duty ratio.
In this embodiment of the application, based on the predetermined deviation value, the current motor speed, and the target motor speed, it may be determined whether the inner fan speed is close to the target value speed, the inner fan speed is not adjusted if the inner fan speed is close to the target value speed, and the current motor speed is adjusted if the inner fan speed exceeds the target value speed.
Optionally, if the current motor rotation speed is higher than the target value rotation speed plus the deviation value, the main controller reduces the PWM pulse duty ratio of the motor; if the current motor rotating speed is lower than the target value rotating speed-deviation value, the main controller increases the PWM pulse duty ratio of the motor; and if the current motor rotating speed is higher than the target rotating speed-deviation value and lower than the target rotating speed + deviation value, the main controller does not change the PWM pulse duty ratio output of the motor. Because the air deflector of the indoor unit circularly moves, the rotating speed of the motor needs to be judged to be within the interval range, and the indoor unit of the air conditioner does not adjust the rotating speed temporarily, so that the adjusting speed of the motor of the air conditioner is reduced, and the fluctuation of the rotating speed of the motor caused by too fast and too slow adjusting of the rotating speed of the motor is reduced.
