The control circuit board 14 is electrically connected to the battery 144 through the battery power supply circuit. All of the above electrical connections are existing technology. See the circuit diagram. Figures 4 to 9 , The control circuit board 14 also includes a charging line, one end of which is electrically connected to the battery 144, and the other end of which is electrically connected to the charging terminal. The bottom cover 19 has a clearance opening corresponding to the charging terminal. In this embodiment, the charging circuit is a TYPE-C port charging circuit. One end of the TYPE-C port charging circuit is electrically connected to the battery 144, and the other end of the TYPE-C port charging circuit is electrically connected to the TYPE-C terminal. A clearance opening is provided on the bottom cover 19 corresponding to the TYPE-C terminal. See the circuit diagram. Figure 10 .

[0020] It also includes a Hall effect switch sensor, which is located in the wireless receiver corresponding to remote controller 1 and is electrically connected to the second microcontroller within the wireless receiver. See the circuit diagram. Figure 11 .

[0021] In this embodiment, the control circuit board 14 is provided with a plurality of buttons 141. The buttons 141 are electrically connected to the first microcontroller through button circuits. A button cover plate 13 is snapped onto the outside of the control circuit board 14. A rubber ring 12 is embedded in the center of the button cover plate 13. A panel 11 is attached to the button cover plate 13 and the rubber ring 12. The panel 11 is provided with corresponding markings. Pressing the panel 11 will activate the corresponding button 141.

[0022] In this embodiment, a thin antenna is provided on the inner side of the panel 11, and the thin antenna is electrically connected to the wireless radio frequency transceiver circuit. Because the bearing 17 is made of metal, it will affect the signal transmission and reception of the wireless transmission module. By setting up the thin antenna, the signal transmission and reception can be enhanced.

[0023] In this embodiment, the control circuit board 14 is equipped with four buttons: up, down, pause, and frequency selection function buttons. For the frequency selection function, this embodiment provides eight frequency bands.

[0024] In this embodiment, see Figure 4 The bottom cover 19 has a waterproof cover 194 at the clearance opening.

[0025] In this embodiment, see Figure 3 The control circuit board is equipped with several LEDs 142. The first microcontroller is electrically connected to the LEDs 142 through a frequency-selective LED display circuit. See the circuit diagram. Figure 6 .

[0029] Usage and working principle: The method and principle of using the remote control 1 to rotate and control the louvers to raise, lower, and flip are existing technologies. For details, please refer to the existing patents mentioned in the background section, and will not be repeated here.

[0030] How to use the wireless induction pairing method: Simply bring the remote control 1 close to the wireless receiver to complete the pairing; Working principle: The Hall effect sensor in the wireless receiver senses the magnetic field generated by the first magnet 18 of the remote control 1. Due to the magnetic field discrimination capability of the omnipolar Hall effect switch, the Hall effect sensor is activated and outputs a signal. This signal is transmitted to the second microcontroller (usually a single-chip microcomputer) within the wireless receiver. Upon receiving this signal, the second microcontroller initiates pairing with the remote control 1, completing the pairing function. (See circuit diagram). Figure 11The process of editing the above steps in the software and then importing the data into the second microcontroller is a standard technique and will not be elaborated upon here. Compared to existing remote control pairing technology, this greatly simplifies the operation process and is more user-friendly.

[0031] Example 2 See Figure 12 The difference from Embodiment 1 is that this embodiment uses a second base 3, the placement surface of which is inclined, and a second magnet is installed inside the placement surface. An iron sheet is placed on the bottom cover 19 and is magnetically attracted to the second magnet. This provides users with more choices.
