Technical Field

[0002] In the field of smart home control, the rotation angle recognition of the knob dimmer switch panel is usually achieved by using devices such as rotary potentiometers and rotary encoders to identify the resistance changes when rotating to different positions or the phase difference changes between conductive contact points to identify the angle point during the rotation process.
[0003] Usually, since the resistance variation range or the number of conductive contact points is determined by the physical characteristics of the device itself, the selection can only be done by selecting a precision specification according to the needs to achieve product dimming. In addition, the current product's rotation points are usually limited to 30 at most, and the maximum recognition accuracy of the knob is only able to recognize a rotation operation every 12 degrees of rotation.
[0004] This will result in the knob switch being unable to customize the dimming accuracy according to the characteristics of the on-site load and the actual requirements of the owner when adjusting the light brightness or light color temperature. At the same time, due to the small number of points that can be rotated, the maximum dimming granularity is not delicate and accurate enough. As a result, it cannot widen the gap in control quality with other products on the market.
[0005] In summary, it is possible to implement customized dimming accuracy switching on the knob dimmer switch panel, while achieving more precise rotation angle recognition. The precision control of light brightness and color temperature can be adjusted according to actual usage scenarios, thereby greatly improving the market competitiveness of the dimming panel.

[0032] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.
[0033] The utility model discloses a knob dimming switch panel device supporting customized dimming precision, which comprises a panel body 1, a knob body and an infrared transmitting and receiving module 3, wherein the knob body comprises a knob inner shaft 2, a knob outer cover 4 and a rotation precision adjustment cover piece 5, the rear end of the panel body 1 is connected to the light load through a thyristor, the knob inner shaft 2 is fixed at the center of the panel body 1, the infrared transmitting and receiving module 3 is placed in an opening above the knob inner shaft 2, the positioning hole on the knob outer cover 4 is aligned with the infrared transmitting and receiving module 3, the rotation precision adjustment cover piece 5 is pasted on the outside of the knob outer cover 4, and the knob outer cover 4 rotates with the knob inner shaft.
[0034] As a preferred embodiment of the utility model, the knob outer cover 4 is a hollow ring with a circular groove on the back, the knob inner shaft 2 is a cylinder, the knob inner shaft is embedded in the knob outer cover, and the knob outer cover can perform 360-degree infinite continuous rotation on a plane.
[0035] As a preferred embodiment of the present utility model, the rotation accuracy adjustment cover is a transparent film, and different transparent films have different numbers of shading points around them.
[0036] As a preferred embodiment of the utility model, the outside of the knob cover supports the pasting of multiple rotation accuracy adjustment covers 5 with different shading points, and the multiple rotation accuracy adjustment covers 5 rotate synchronously with the knob cover.
[0037] As a preferred embodiment of the present utility model, the panel body 1 is connected to the control circuit of the knob body through SPI, the infrared transmitting and receiving module 3 is connected to the inner shaft of the knob through IIC, and the infrared transmitting and receiving module 3 is connected to the MCU through IIC.
[0038] In a specific embodiment of the utility model, a knob dimming switch panel with customizable dimming accuracy is provided in the field of smart home control devices, which solves the problem of the fixed number of rotation points of the knob dimming panel and meets the different requirements of dimming accuracy and fineness for different application scenarios on site. By increasing the number of rotation angles of the identified knob, the transition of the dimming process can be made smoother. At the same time, the customized accuracy makes the trial range of the product wider, and the load can achieve more accurate brightness and color temperature values.
[0039] The utility model discloses a knob dimming switch panel with customizable dimming accuracy, comprising a panel body 1, a knob inner shaft 2, an infrared transmitting and receiving module 3, a knob outer cover 4, and a rotation accuracy adjustment cover sheet 5.
[0040] The rear part of the panel body 1 of the switch panel controls the light load dimming through the thyristor, and the step accuracy control of the dimming power is determined by the number of knob rotation points recognized by the front infrared transmitting and receiving module 3 per unit time.
[0041] The inner shaft of the knob of the switch panel is fixed on the dimming panel body 1, and a hole is opened above the inner shaft of the knob to expose the infrared transmitting and receiving module. The infrared transmitting and receiving module communicates with the MCU via IIC.
[0042] like Figure 1 As shown, the panel body and the light load are connected through a thyristor solution to achieve a strong electric dimming solution. The panel body and the knob inner shaft control circuit communicate through SPI. The infrared transmitting and receiving module communicates with the knob inner shaft through IIC. The rotation accuracy adjustment cover 5 gives different rotation signals to the infrared transmitting and receiving module by reflecting the intensity of the emitted infrared.
[0043] After power-on, the infrared transmitter and receiver module transmits and receives infrared signals at a frequency of 4Hz. When the infrared transmitter and receiver module is transmitting and receiving, if the difference between two consecutive received energies is between 2000, it is considered to have rotated one point.
[0044] When the MCU determines that the rotation is one point within 1 second, the step will be 1%. When the MCU determines that the rotation is more than one point within 1 second, the step will be 5% for each point.
[0045] As shown in Fig. 2, the panel body includes three main parts: the knob inner shaft, the knob outer cover and the rotation accuracy adjustment cover 5. The knob inner shaft device is fixed in the center of the panel body, and the infrared transmitting and receiving module is located above the front of the knob inner shaft.
[0046] As shown in Figure 3, the knob cover is cylindrical in shape. The front view is a circular ring with a hollow center and a semi-translucent edge. The back is a circular groove. There is a positioning hole above the front view of the cover to facilitate alignment with the infrared transmitter and receiver modules on the inner shaft of the knob during installation. Figure 3c A schematic diagram of the cover rotating on the inner shaft is also shown.
[0047] As shown in FIG. 4 , the inner shaft of the knob is cylindrical, with an infrared transmitting and receiving module at the top, and the transmitting and receiving parts are circular windows.
[0048] As shown in FIG. 5 , the knob outer cover and the knob inner shaft can be combined together, and the knob inner shaft is embedded in the knob outer cover. When the knob outer cover rotates, the inner shaft does not move, and the knob outer cover can rotate 360 degrees continuously on a plane.
[0049] As shown in FIG6 , the rotation accuracy adjustment cover is a transparent film with different numbers of light shielding points around the film, and two films can overlap each other at the cross-shading points.
[0050] As shown in FIG. 7 , a rotation accuracy adjustment cover sheet 5 with different shading points can be pasted on the outside of the knob cover, and the cover sheet rotates synchronously with the knob cover during rotation.
[0051] The knob outer cover 4 is rotated based on the knob inner shaft. During factory installation, the infrared transmitting and receiving module 3 on the knob inner shaft 2 is aligned and assembled through the positioning hole on the knob outer cover 4. After equipment, infrared calibration is performed. After the calibration is completed, the rotation accuracy adjustment cover 5 with the universal point number is affixed.
[0052] Rotate the knob cover. Assuming that the rotation speed remains unchanged, the greater the density of the shading points of the rotation accuracy adjustment cover, the more frequent the difference changes recognized by the infrared emission and receiving modules 3 of the component per unit time. The corresponding logic judgment of the MCU is that the more points are rotated, the adjustment trend will change to 5% for each point. The dimming panel will adjust the load faster and more obviously, which means that the knob adjustment is more sensitive and more accurate.
[0053] When the on-site load requires a higher and faster dimming experience, the rotation accuracy adjustment cover 5 can be replaced or combined to increase the shading point density to achieve it.
[0054] When the load dimming range on site is narrow, the sensitivity and change process of dimming can be slowed down by replacing the rotary precision adjustment cover 5 to reduce the density of shading points.
[0055] In this solution, when the knob cover rotates, the infrared transmitting and receiving modules receive infrared reflected light of different intensities by precisely adjusting the light-transmitting and light-shielding positions of the cover to determine the current rotation state. The number of rotation points of the knob can be customized by adjusting the light-shielding position of the light-shielding film or combining different precision-adjustable covers. The number of rotation points determines the difference in load dimming accuracy.
[0056] The working principle of the utility model is as follows:
[0057] The inner shaft of the knob is fixed to the switch body through a structure.
[0058] The infrared transmitting and receiving modules on the inner shaft of the knob communicate with the MCU through IIC.
[0059] The infrared transmitting and receiving module determines whether there is a change in the reflection value in front by transmitting and receiving reflected infrared signals.
[0060] During the rotation process, the outer cover determines the density of different shading points during the rotation process by covering different precision adjustment cover pieces, so that the infrared transmitting and receiving modules can detect the rotation action during the rotation process.
[0061] The infrared transmitting and receiving modules transmit the identified rotating points to the MCU, and the MCU determines the dimming step accuracy and adjustment speed according to the number of rotating points and the speed at which the two points arrive.
[0062] This device can customize the knob dimming switch panel of dimming precision; different dimming precisions can be switched according to the actual user's demand for dimming fineness; secondary precision adjustment can be performed according to the performance difference of actual on-site load dimming; the number of dimming rotation points can be increased to 60 by adjusting the density and size of the shading position compared to the traditional 30 points.

[0064] It can be understood that the same or similar parts of the above embodiments can be referenced to each other, and the contents not described in detail in some embodiments can refer to the same or similar contents in other embodiments.
