Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0027] Figure 1 and Figure 2 The middle part is a concealed multi-functional wireless control box for electric louvered glass, including a housing 1 and a main circuit board 2, which is generally hidden inside the wall. In this embodiment, the housing 1 is formed by a front cover 11 and a bottom cover 12 fastened together;

[0028] See Figure 3 and Figure 6 The main circuit board 2 is equipped with a microprocessor (MCU), a transformer circuit, a voltage regulation circuit, a wireless transceiver processing circuit, and button and indicator light circuits. (See attached diagram.) Figure 4 and Figure 5 The transformer circuit is connected to an external AC power supply (220V) via power interface 23. The other end of the transformer circuit (output 5V) is electrically connected to the voltage regulator circuit 3. The voltage regulator circuit 3 (output 3.3V) supplies power to the components on the main circuit board 2. See [link / reference]. Figure 8 The main circuit board 2 is equipped with an RS485 communication circuit, see [link / reference]. Figure 9 The main circuit board 2 has several dry contact circuits.

[0029] In this embodiment, the RS485 communication circuit is connected to an RS485 interface 21, and the main circuit board 2 is electrically connected to the smart home control system through the RS485 interface 21.

[0030] In this embodiment, the dry contact circuit is connected to the dry contact interface 24, and the main circuit board 2 is electrically connected to the external controller through the dry contact interface 24.

[0031] In this embodiment, the dry contact circuit has 5 dry contacts, which correspond to the functions of raising, lowering, flipping, pausing, and frequency modulation of the blinds.

[0032] Dry contact communication requirements: Single channel. Can control ≥ 320 glass panels, which can only move simultaneously. In dry contact communication mode, GND or the common terminal must be negative, and the other ports must be positive. Dry contact mode requires that on / off signals and high / low frequency signals are also available. It can be used with Huawei and other smart home devices. Default is high level; low level indicates a button is pressed.

[0033] Dry contact communication control logic: After the receiver enters the pairing state, press the pairing button briefly for 3 seconds. The motor will then reverse direction once more, indicating successful pairing. At this point, the system enters group control mode (the receiver supports learning group control codes). Pairing with the remote control is not required; the remote control and receiver are paired separately. Multiple photoelectric control boxes using dry contact functionality can be connected to a smart home system. Each box can be used individually when needed; group control requires a certain distance to prevent signal interference.

[0034] In this embodiment, see Figure 7 The wireless transceiver processing circuit also includes a wireless antenna, and the main circuit board 2 is wirelessly connected to several wireless transceiver devices through the wireless antenna. In this embodiment, a 433 RF signal is transmitted to control the distance of the louvered glass to be ≥40 meters.

[0035] In this embodiment, see Figure 10 The button and indicator circuit includes a spring-loaded button 22, whose function is set to write code and dry contact code pairing. LEDs are also provided to indicate the status.

[0036] In this embodiment,

[0037] 485 communication requirements: Channel settings can be set from 0X00 to 0XFF, and channels can be controlled individually or in groups. A single channel can control 20 to 40 glass panels.

[0038] 485 communication control logic: When pairing with the receiver, after the receiver enters the pairing state, the 485 communication serial port outputs the pairing signal. If the motor reverses once in the forward or reverse direction, the pairing is successful.

[0039] The channel bit of the 485 communication can be set to any address, up to 0xFF, and can be paired with the receiver (the receiver firmware cannot be updated).

[0040] No pairing code is required with the remote control; the remote control and receiver are paired separately.

[0058] Send 2 to 3 data packets consecutively with an interval of 100-200ms between them to ensure that the data is received normally.

[0059] Pairing method: (Only one code is stored, and subsequent pairing will overwrite the previous code)

[0060] Press the up and down buttons of the motor simultaneously. After the motor stops reversing, press the up button again within 10 seconds. The indicator light will start flashing and a data packet with the AA command will be sent to match the current code.

[0061] Wiring configuration: TXD-----A, RXD-----B, Common-----GND.

[0062] In this embodiment, the PY32F030K28 microcontroller is used as the microprocessor (MCU).

[0063] The wireless driver unit uses a 433MHz wireless transmitter module, which is connected to a 3.3V voltage. The 433MHz wireless transmitter module is connected to the SCLK, SDLO, CBS, and FCBS pins of the microcontroller.

[0064] The RS-485 communication unit is electrically connected to the transformer circuit and the MCU-RS\485-CS\MCU-TX pins of the microcontroller to achieve control.
