As shown in fig. 3, at step B: when the motor stalling of adjusting luminance, whether the angle of adjusting luminance that detects intelligent (window) curtain is in first preset state, if, stop including in the motor pivoted step of adjusting luminance:
b1: when the dimming motor is locked, detecting whether dimming angles of all the moving balls are in a first preset state;
b2: when the dimming angle of at least one walking ball is detected not to be in a first preset state, the dimming shaft is continuously rotated towards the rotation blocking direction, and the dimming shaft drives the dimming angle of the walking ball to change until all the dimming angles of the walking ball are in the first preset state.
Specifically, when the dimming motor 100 is locked, the ball 120 in the first preset state does not rotate any more, and if the dimming axis 110 continues to rotate at this time, the ball 120 in the first preset state slips with the dimming axis 110, the ball 120 does not rotate any more, and the ball 120 with the dimming angle not in the first preset state does not slip with the dimming axis 110, and the ball continues to rotate to the first preset state until the dimming angles of all the balls 120 are in the first preset state. In general, since the dimming angles of the plurality of beads 120 do not rotate after reaching the first preset state, a large resistance is generated to affect the dimming motor 100 through the dimming axis 110, and the power of the dimming motor 100 is limited, and the dimming motor cannot rotate continuously under the condition of a large resistance, at this time, the dimming axis 110 can be continuously rotated by a manual or external machine until all the dimming angles of the plurality of beads 120 are in the first preset state, and the dimming axis 110 is not rotated any more.
This application is hindered at dimming motor 100 and is hindered the power influence, when unable continuation rotation, continues to rotate dimming axle 110 through external machine or manual work for the angle of adjusting luminance is not in walking of first preset state pearl 120 and can continue rotatoryly, and the angle of adjusting luminance of walking pearl 120 all is in first preset state up to all. The problem of adjust luminance the motor 100 and be influenced by the resistance, can't continue to rotate, lead to adjusting luminance the angle and not being in the unable rotation to first predetermined state of adjusting luminance of walking pearl 120 of first predetermined state is solved. And when the dimming angles of all the beads 120 are uniform, the beads are in a first preset state, namely the dimming angle is 0 degree, the dimming angle and the Hall signal are conveniently aligned, and the problem that the dimming angle and the Hall signal are not aligned due to the influence of external force factors on the intelligent curtain is solved.
As shown in fig. 4, in step C: detecting whether the Hall signal is in a second preset state, if not, the step of setting the Hall signal to be in the second preset state comprises the following steps:
c1: the dimming motor rotates forwards;
c2: when the stroke of the dimming motor is equal to the preset maximum value of the Hall signal, detecting whether the dimming angle is in a third preset state;
wherein, the third preset state is the maximum dimming angle.
Specifically, when the stroke of the dimming motor 100 is equal to the preset maximum value of the hall signal, it represents that the hall signal is precisely aligned with the dimming angle. The stroke of the dimming motor 100, that is, the number of turns of the dimming motor 100 to be rotated from the minimum dimming angle to the maximum dimming angle, may be detected by the hall signal scanning element 130, the hall signal scanning element 130 scans and records the number of times the magnet 140 passes through in the circumferential array direction of the magnet 140, when the first scanned magnet 140 is scanned and recorded by the hall signal scanning element 130 again, the number of turns of the magnet 140 is added by 1, and the number of turns of the magnet 140 is the number of turns of the dimming motor 100. Whether the dimming angle is aligned with the hall signal one by one as shown in the above table is detected by detecting whether the forward rotation stroke of the dimming motor 100 is equal to the maximum value of the hall signal.
In the step where the third preset state is the maximum dimming angle, the maximum dimming angle is the forward rotation of the dimming motor 100, and drives the dimming angle to be adjusted toward the direction opposite to the first preset state, when the dimming motor 100 is locked, the dimming angle stops being adjusted, and the dimming angle at this time is the maximum dimming angle.
Specifically, after the forward rotation of the dimming motor 100 is stopped, a forward rotation instruction of the dimming motor 100 is continuously given to drive the dimming motor 100 to rotate, at this time, whether the dimming motor 100 is locked or not can be judged by detecting whether the dimming angle is changed or not, if the dimming angle is not changed, the dimming motor 100 is locked or not, the stroke of the dimming motor 100 is equal to the preset maximum value of the hall signal, and if the dimming angle is changed again, the stroke of the dimming motor 100 is unequal to the preset maximum value of the hall signal or the dimming angle is not aligned to the value of the hall signal, which indicates that the intelligent curtain is in error during assembly or production and needs to be returned to the factory for maintenance.
This embodiment is through above-mentioned step, does a detection to the counterpoint condition of angle of adjusting luminance and hall signal numerical value, avoids adjusting luminance after spacing setting up the completion, and angle of adjusting luminance is not counterpointed with hall signal numerical value, leads to the unable accurate regulation and control of angle of adjusting luminance of accomplishing in the user's use.
In another embodiment, after step C, the dimming motor hall signal is calculated by two stalls, the steps comprising:
the dimming motor rotates forwards;
stopping the dimming motor, and detecting whether the dimming motor is locked;
and detecting whether the dimming angle of the intelligent curtain is in a third preset state, if so, calculating numerical information equal to the Hall signal according to the stroke information of the dimming motor.
In this embodiment, be provided with two stifled commentaries on classics positions between the axle of adjusting luminance that this dimming motor is connected and the walking ball, rotate clockwise when adjusting luminance the axle promptly and then form stifled commentaries on classics for the first time to a certain position, after the stifled commentaries on classics for the first time, anticlockwise rotation rotates to a certain position then forms stifled commentaries on classics for the second time. Changing the stroke between two times of locked rotor is the formation information of the dimming motor, when the dimming shaft rotates from the position of the first locked rotor to the position of the second locked rotor, the Hall signals are recorded for x times totally, the 0-x times of recording is the stroke information of the Hall signals, and x is the maximum numerical value of the Hall signals and corresponds to the state that the dimming angle is 0 or 180 degrees. The stroke information of the Hall signals can be not preset in the embodiment, and the two-time locked-rotor position can be adjusted according to the actual position, so that the numerical value of each Hall signal corresponds to the dimming angle within the range one by one, and the intelligent window curtain is more intelligent and suitable for different intelligent window curtains.
In this embodiment, after the smart window curtain completes the step of setting the dimming limit, when a first adjustment instruction for adjusting the dimming angle is received, where the first adjustment instruction includes a first preset value of the dimming angle, the driving mechanism drives the dimming motor 100 to rotate, the dimming motor 100 drives the first dimming gear 150 to rotate, the first dimming gear 150 drives the second dimming gear 160 to rotate, the second dimming gear 160 drives the dimming shaft 110 to rotate, the dimming shaft 110 drives the ball 120 to rotate, and the detection mechanism operates to detect whether the dimming angle reaches the first preset value, and when the dimming angle reaches the first preset value, the dimming motor 100 stops rotating.
When a second adjusting instruction for adjusting the dimming angle given by the user is received, wherein the second adjusting instruction includes a second preset value of the dimming angle, a preset value of a hall signal corresponding to second preset value information of the dimming angle is correspondingly searched according to the second preset value of the dimming angle of the second adjusting instruction, the driving mechanism drives the dimming motor 100 to rotate, the dimming motor 100 drives the first dimming gear 150 to rotate, the first dimming gear 150 drives the second dimming gear 160 to rotate, the second dimming gear 160 drives the dimming shaft 110 to rotate, the dimming shaft 110 drives the ball 120 to rotate, meanwhile, the detection mechanism operates to detect whether the dimming angle reaches the second preset value, and when the dimming angle reaches the second preset value, the driving mechanism drives the dimming motor 100 to stop rotating.
It should be noted that, when a second adjustment instruction is received, the difference between the preset values of the hall signals corresponding to the first preset value and the second preset value of the dimming angle is calculated, and according to the difference, the rotation direction of the dimming motor 100 is selected, when the second preset value is greater than the first preset value, that is, the difference is a positive number, the dimming motor 100 rotates in the forward direction, and if the second preset value is less than the first preset value, that is, the difference is a negative number, the dimming motor 100 rotates in the reverse direction.
