Fig. 4 is a flowchart of a method for detecting the slippage of the curtain motor according to an embodiment of the present invention, which can be applied to the curtain motor in the above embodiments. The method comprises the following steps:
s101, controlling the curtain motor to move in the horizontal direction, and acquiring the acceleration of the curtain motor in the moving process through the acceleration sensor.
The acceleration acquired by the acceleration sensor may specifically be a three-axis acceleration, that is, an acceleration of X, Y, Z axis.
S102, detecting whether the driving wheel and the curtain track slide or not according to the acquired change condition of the acceleration.
In this embodiment, the detecting whether the driving wheel slips from the track of the window curtain according to the collected change of the acceleration includes: acquiring a change waveform of the acceleration and time according to the acquired acceleration; and when the fluctuation value of the waveform of the acceleration in a time period is smaller than a first preset threshold value and larger than a second preset threshold value, and the acceleration change characteristic corresponds to the end point of the time period, determining that the driving wheel and the track of the curtain are in a slip state. The variation characteristic of the acceleration comprises: the acceleration is changed from a first acceleration to a second acceleration, wherein the first acceleration is larger than the second acceleration, and the difference value of the first acceleration and the second acceleration is larger than a preset threshold value.
The first preset threshold and the second preset threshold represent the fluctuation value of the waveform, the fluctuation of the waveform is larger when the first preset threshold is larger than the first preset threshold, and the fluctuation of the waveform is smaller when the second preset threshold is smaller than the second preset threshold. The first preset threshold and the second preset threshold can be set systematically or manually, and the first preset threshold and the second preset threshold can be determined through repeated experiments. The first acceleration can be far larger than the second acceleration, and the larger the difference value between the first acceleration and the second acceleration is, the larger the fluctuation value of the corresponding waveform is, that is, the more obvious the acceleration change characteristics at the critical positions of different states are, so that the operation state of the curtain motor can be accurately distinguished.
After the slip state is determined according to the first preset threshold and the second preset threshold, the normal running state and the stop state of the curtain motor can be determined. Namely, when the fluctuation value of the waveform of the acceleration in a time period is greater than the first preset threshold value and the acceleration change characteristic corresponds to the end point of the time period, determining that the curtain motor is in the running state; and when the fluctuation value of the waveform of the acceleration in a time period is smaller than the second preset threshold value, determining that the curtain motor is in a static state.
For example, as shown in fig. 5, fig. 5 is a schematic diagram of the variation trend of the triaxial acceleration in different states. The three axes are respectively an X axis, a Y axis and a Z axis, and when the curtain motor moves horizontally, if the curtain motor is in a normal operation state, the acceleration change of the X, Y, Z three axes is large, and the fluctuation value of the waveform is large; if the state is a slipping state, the acceleration change of the three shafts X, Y, Z is small, and the fluctuation value of the waveform is small; if the vehicle is in a stop state, the acceleration of the three shafts X, Y, Z is basically unchanged, and the fluctuation value of the waveform is basically zero. In addition, the critical points of the three states correspond to acceleration change characteristics, and the acceleration change characteristics are used for indicating that the acceleration has larger acceleration change at the adjacent time point.
According to the method for detecting the slippage of the curtain motor, provided by the embodiment of the invention, the curtain motor is controlled to move in the horizontal direction, and the acceleration of the curtain motor in the moving process is acquired through the acceleration sensor; and detecting whether the driving wheel and the track of the curtain slip or not according to the acquired change condition of the acceleration. According to the method, on one hand, because the stroke of the curtain motor needs to be automatically detected when the curtain motor is installed for the first time, the method provided by the embodiment of the invention can be unfolded when the stroke of the curtain motor is automatically detected when the curtain motor is installed for the first time, so that the process is saved; on the other hand, the curtain motor can automatically detect the slipping phenomenon generated when the curtain is opened or closed, so that the holding function is started when the slipping occurs, and the stability of the curtain is improved.
Fig. 6 is a flowchart of a method for detecting a curtain motor slipping according to another embodiment of the present invention, and fig. 6 is different from fig. 4 mainly in that the method further includes:
s103, obtaining the displacement of the curtain motor in the moving process according to the acceleration;
s104, detecting the change condition of the displacement, and if the displacement is not changed within the preset time and a motor stop instruction is not detected, determining that the driving wheel and the track of the curtain tightly held by the driving wheel are in a slipping state.
The embodiment of the invention detects whether the slip phenomenon occurs according to the displacement change condition of the curtain motor. When the curtain motor starts to move horizontally, the acceleration value of the curtain motor is output through the acceleration sensor, and the displacement of the curtain motor can be obtained by performing double integration on the acceleration value. And if the curtain motor is not indicated to stop working and the detected displacement of the curtain motor is not increased any more, the curtain motor can be determined to slip.
The method provided by the embodiment of the invention is based on the method embodiment, and further detects whether the curtain motor slips or not by detecting the displacement change of the curtain motor, and the method can also be applied to the process of stroke self-detection when the curtain motor is installed for the first time, so that whether the curtain motor slips or not is automatically detected after the curtain motor is installed for the first time, and the detection is carried out by double guarantee of acceleration change and displacement change, so that the stable operation of the curtain is greatly improved, and the user experience can be improved.
It should be noted that, the slippage phenomenon of the curtain motor may also be detected only by the change of the displacement. Of course, other methods than detecting the slip phenomenon based on the change in acceleration and the change in displacement may be employed. In addition, in the daily use process of the curtain, whether the curtain motor slips or not can be detected by the method provided by the embodiment of the invention, so that the curtain motor can be ensured to stably operate, and the service life of the curtain motor is prolonged.
The embodiment of the invention also provides a curtain, which comprises a curtain rail, a curtain fabric and the curtain motor in the embodiment, wherein the curtain motor is used for driving the curtain fabric to move on the curtain rail, and the curtain motor can also be specifically used for executing the method in the method embodiment. The curtain motor can be connected with a curtain hook on a curtain rail through a host hanging buckle arranged on the curtain motor, so that the curtain motor is connected with the curtain. The curtain motor can also with other modes with the curtain is connected, for example, one side of curtain track still is equipped with transmission case and supplies the motor mount pad of curtain motor setting, the motor mount pad can dismantle set up in on the transmission case, run through on the motor mount pad and set up the perforation that supplies the motor shaft to pass. In this embodiment, the curtain motor may be connected to the curtain in various ways, not limited to the above two ways.
The curtain provided by the embodiment of the invention can stably run in the automatic opening and closing processes of the curtain cloth, so that the unstable phenomena such as slipping are avoided, and the performance of the curtain is integrally improved.
