When the stepping motor 13 rotates in the forward direction, the knob contact 1211 rotates toward the first fixed end 1213.
With reference to fig. 3, an embodiment of the present disclosure provides a method for controlling a wind deflector, including:
s210, the processor detects the current voltage value of the variable end.
S220, the processor determines a target voltage value of the variable end.
And S240, controlling the stepping motor to rotate by the processor under the condition that the current voltage value is different from the target voltage value.
And S280, controlling the stepping motor to stop rotating by the processor under the condition that the current voltage value is the same as the target voltage value.
By adopting the method for controlling the air deflector provided by the embodiment of the disclosure, the stepping motor drives the knob contact piece of the slide rheostat and the air deflector to rotate, and the rotation angle of the knob contact piece corresponds to that of the air deflector, so that the voltage value of the variable end corresponds to that of the air deflector. And detecting the current voltage value of the variable end to obtain the current angle of the air deflector. And determining a target voltage value of the variable end corresponding to the target angle of the air deflector. Under the condition that the current voltage value is different from the target voltage value, the air deflector is not positioned at the target angle, and the stepping motor is controlled to drive the knob contact piece to rotate to change the current voltage value and drive the air deflector to rotate to change the current angle of the air deflector. And under the condition that the current voltage value is the same as the target voltage value, indicating that the air deflector is already at the target angle, and controlling the stepping motor to stop rotating. And determining whether the air deflector is positioned at a target angle or not and controlling the stepping motor through the current voltage value of the variable end of the slide rheostat so as to improve the accuracy of controlling the rotation of the air deflector of the air conditioner.
Optionally, the processor in step S220 determines a target voltage value of the variable terminal, including: the processor determines a target angle for the air deflection plate. And the processor determines a target voltage value of the variable end according to the target angle. Thus, the target voltage value corresponding to the variable end of the slide rheostat is determined according to the target angle required to be opened by the air deflector. And under the condition that the current voltage value is different from the target voltage value, controlling the stepping motor to rotate so as to enable the current angle of the air deflector to gradually reach the target angle, so as to improve the accuracy of controlling the rotation of the air deflector of the air conditioner.
As shown in fig. 2-2 and fig. 2-3, optionally, the processor determines the target voltage value of the variable terminal according to the target angle, including: u shapet＝(UV-Ui)×θt/θm+Ui. Wherein, UtIs a target voltage value, UVTo the value of the supply voltage, UiIs a minimum voltage value, θtIs the target angle, θmIs the maximum angle. For the voltage divider circuit of FIGS. 2-2, UiIs 0V. For the voltage divider circuits of FIGS. 2-3, Ui＝UV×Rd/(Rm+Rd). Wherein R isdIs the resistance value of a voltage dividing resistor, RmThe maximum resistance value of the sliding rheostat. Therefore, the target voltage value can be calculated according to the target angle of the air deflector, so that the accuracy of controlling the rotation of the air deflector of the air conditioner is improved.
The above two formulas for determining the target voltage value of the variable end are suitable for the situation that the rotation range of the knob contact of the slide rheostat is completely the same as that of the air deflector. Namely, when the air deflector rotates to the maximum angle, the knob contact is positioned at the first fixed end, and the maximum voltage value of the variable end is the power supply voltage value. When the air deflector rotates to the minimum angle, the knob contact is located the second stiff end, and the voltage value of variable end is minimum voltage value. In actual design, certain deviation exists or the rotation ranges of the deviation and the rotation ranges are not completely the same, and only the voltage parameter in the formula needs to be corrected.
Optionally, the larger the current voltage value of the variable end is, the larger the current angle of the wind deflector is. When the stepping motor rotates forwards, the angle of the air deflector is increased. In this way, the direction of rotation of the stepper motor is synchronized with the current voltage value and the current trend of change of the angle. Namely, when the automobile rotates in the forward direction, the current voltage value and the current angle are increased; when the rotation is reversed, the current voltage value and the current angle are reduced. And judging the magnitude relation between the current angle and the target angle according to the magnitude relation between the current voltage value and the target voltage value. The current voltage value and the current angle are increased by controlling the stepping motor to rotate forwards and reduced by rotating backwards, the current voltage value is adjusted to a target voltage value, and the current angle is adjusted to a target angle, so that the accuracy of controlling the air deflector of the air conditioner to rotate is improved.
With reference to fig. 4, another method for controlling a wind deflector is provided in an embodiment of the present disclosure, including:
and S200, initializing the air deflector by the processor.
S210, the processor detects the current voltage value of the variable end.
S220, the processor determines a target voltage value of the variable end.
S230, the processor judges whether the current voltage value is the same as the target voltage value. If yes, go to step S280. If not, go to step S241.
S241, the processor judges whether the current voltage value is larger than the target voltage value. If yes, go to step S242. If not, go to step S243.
S242, the processor controls the stepping motor to rotate in reverse, and returns to step S210.
S243, the processor controls the stepping motor to rotate forward, and returns to step S210.
And S280, controlling the stepping motor to stop rotating by the processor.
By adopting the method for controlling the air deflector, provided by the embodiment of the disclosure, the rotating direction of the stepping motor can be determined according to the current voltage value and the target voltage value. The current voltage value and the current angle are increased by controlling the stepping motor to rotate forwards and reduced by rotating backwards, the current voltage value is adjusted to a target voltage value, and the current angle is adjusted to a target angle, so that the accuracy of controlling the air deflector of the air conditioner to rotate is improved.
Optionally, the processor in step S200 initializes the air deflector, including: the processor looks for a reference position of the air deflection plate. In the case of finding the reference position, the processor detects the reference voltage value of the variable terminal. The processor determines a relationship between the angle of the air deflector and the voltage value of the variable terminal according to the reference position and the reference voltage value. Therefore, the relation between the initial angle of the air deflector and the variable terminal voltage value can be determined, and the error between the angle and the voltage value in the rotation control process of the air deflector is reduced, so that the rotation accuracy of the air deflector of the air conditioner is improved.
The reference position of the air deflector is the position of the air deflector when the air deflector is reset. The reference position is divided into the following two types according to the design of the air conditioner structure: when the stepping motor rotates reversely, the angle of the air deflector is always 0 degrees, and the air deflector is in a closed state. Or when the stepping motor rotates forwards, the angle of the air deflector is always the maximum angle, and the air deflector is in a fully-opened state. When the reference position of the air deflector is found, the processor controls the stepping motor to stop rotating.
With reference to fig. 5, another method for controlling a wind deflector is provided in an embodiment of the present disclosure, including:
s210, the processor detects the current voltage value of the variable end.
S220, the processor determines a target voltage value of the variable end.
And S240, controlling the stepping motor to rotate by the processor under the condition that the current voltage value is different from the target voltage value.
S250, the processor detects the current voltage value of the variable terminal again.
S260, the processor determines the difference value between the current voltage value and the previous voltage value.
And S270, under the condition that the sign of the difference value of the voltage values is opposite to the rotating direction of the stepping motor, the processor controls the stepping motor to stop rotating, prompts that the air deflector rotates abnormally, and ends the control.
And S280, controlling the stepping motor to stop rotating by the processor under the condition that the current voltage value is the same as the target voltage value.
By adopting the method for controlling the air deflector provided by the embodiment of the disclosure, whether the rotating direction of the stepping motor is abnormal or not can be judged according to the voltage values detected twice before and after the stepping motor rotates. When the rotating direction of the stepping motor is opposite to the expected direction, the stepping motor or the control circuit is in failure, and the air deflector can be damaged due to continuous operation. At the moment, the stepping motor is controlled to stop rotating, the abnormal rotation of the air deflector is prompted, a user is informed of the need of maintenance, and the air deflector is prevented from being damaged.
Alternatively, in a case where the sign of the difference in the voltage values is positive and the direction in which the stepping motor is controlled to rotate is reverse, the processor determines that the sign of the difference in the voltage values is opposite to the direction in which the stepping motor rotates. Alternatively, in the case where the sign of the difference in voltage values is negative and the direction in which the stepping motor is controlled to rotate is positive, the processor determines that the sign of the difference in voltage values is opposite to the direction in which the stepping motor rotates. Therefore, whether the rotating process of the stepping motor is abnormal or not is judged conveniently through the direction relation between the sign of the difference value of the preset voltage value and the signal for controlling the rotation of the stepping motor, and the damage of the stepping motor is avoided.
With reference to fig. 6, another method for controlling a wind deflector is provided in accordance with an embodiment of the present disclosure, including:
s210, the processor detects the current voltage value of the variable end.
S220, the processor determines a target voltage value of the variable end.
And S240, controlling the stepping motor to rotate by the processor under the condition that the current voltage value is different from the target voltage value.
S250, the processor detects the current voltage value of the variable terminal again.
S260, the processor determines the difference value between the current voltage value and the previous voltage value.
And S271, under the condition that the absolute value of the difference value of the voltage values is greater than the difference threshold value, the processor controls the stepping motor to stop rotating, prompts abnormal rotation of the air deflector and ends the control.
And S280, controlling the stepping motor to stop rotating by the processor under the condition that the current voltage value is the same as the target voltage value.
By adopting the method for controlling the air deflector provided by the embodiment of the disclosure, whether the rotating speed of the stepping motor is abnormal or not can be judged according to the voltage values detected twice before and after the stepping motor rotates. When the rotating speed of the stepping motor exceeds the expected maximum speed, the stepping motor is indicated to have a fault, and the continuous operation can cause the damage of the stepping motor and the air deflector. At the moment, the stepping motor is controlled to stop rotating, the abnormal rotation of the air deflector is prompted, a user is informed of the need of maintenance, and the air deflector is prevented from being damaged.
As shown in fig. 2-2 and fig. 2-3, the case that the absolute value of the difference of the voltage values in step S271 is greater than the difference threshold is reflected that the rotation speed of the stepping motor exceeds the expected maximum speed, or reflected that the rotation angle of the stepping motor and/or the air deflector within a certain time exceeds the expected maximum angle. The relation between the rotating angle of the air deflector and the voltage value of the variable end is as follows: Δ θ ═ U2-U1)/(UV-Ui)×θm. Wherein, Delta theta is the angle of rotation, U2Is the current voltage value, U1Is the previous voltage value, UVTo the value of the supply voltage, UiIs a minimum voltage value, θmIs the maximum angle. For the voltage divider circuit of FIGS. 2-2, UiIs 0V. For the voltage divider circuits of FIGS. 2-3, Ui＝UV×Rd/(Rm+Rd). Wherein R isdIs the resistance value of a voltage dividing resistor, RmThe maximum resistance value of the sliding rheostat.
With reference to fig. 7, another method for controlling a wind deflector is provided in an embodiment of the present disclosure, including:
s210, the processor detects the current voltage value of the variable end.
S220, the processor determines a target voltage value of the variable end.
And S240, under the condition that the current voltage value is not the same as the target voltage value, the processor controls the stepping motor to rotate and returns to the step S210.
And S280, controlling the stepping motor to stop rotating by the processor under the condition that the current voltage value is the same as the target voltage value.
S250, the processor detects the current voltage value of the variable terminal again.
S260, the processor determines the difference value between the current voltage value and the previous voltage value.
And S272, under the condition that the difference value of the voltage values is not zero, prompting that the air deflector rotates abnormally by the processor.
By adopting the method for controlling the air deflector provided by the embodiment of the disclosure, whether the stepping motor continues to rotate or not can be judged according to the voltage values detected twice before and after the stepping motor stops rotating. When the stepping motor rotates without rotating, the fault of the stepping motor is proved, and the air deflector can be damaged. At the moment, the abnormal rotation of the air deflector is prompted, a user is informed of the need of maintenance, and the air deflector is prevented from being damaged.
