[0037] The following will further explain this technical solution in detail:

[0038] Figure 1 This is a schematic diagram of the entire main panel of the single-fire single-control dual-control dimmer switch circuit structure of this technical solution, including the main panel power supply, the slave panel power supply communication unit, the load switch unit, the zero point circuit unit, the interactive unit and the main control unit;

[0039] Figure 2 This is a schematic diagram of the main panel power supply structure, which is mainly used to power the entire main panel and supply power to the slave panels through the slave panel power supply communication unit. The key points of this circuit structure are to use an isolated power supply and realize the common ground L-GND of the live wire;

[0040] Figure 3 This is a schematic diagram of the structure of the slave panel power supply communication unit, which is mainly used to obtain power from the slave panel and communicate with the master panel. Figure 3 As shown, the master panel supplies power to the slave panel via RT1 and D3 from the dual-control C port. The master and slave panel MCUs complete bidirectional communication through the dual-control C port by reading RX and controlling TX. It should be noted that RX needs to use the internal pull-down resistor of the MCU.

[0041] Figure 4 The waveform structure diagram of RX and TX is shown below. By changing the transmission frequency and duty cycle of TX, the on / off state, brightness state and indicator light state of the light can be transmitted.

[0042] The load switch unit is mainly used to control the on and off of the load lamp, and this part mainly includes a MOS tube or a thyristor;

[0043] The zero point circuit unit is mainly used by the MCU to detect the zero point of the AC power, thereby determining the frequency of the AC power and serving as a basis for determining whether to turn on or off the load, thereby achieving different brightness changes.

[0044] The interactive unit is mainly used for human-computer interaction input, which can be a mechanical button, touch button or encoder, etc. The MCU detects the button switch time to determine whether it is a short press or a long press, and realizes the switch and dimming of the load lamp;

[0045] The main control unit is mainly composed of MCU and MOS tube or thyristor drive circuit, which is used for the logic control of the entire system. The entire system needs to maintain low power consumption;

[0046] The single-fire, single-control, dual-control dimmer switch circuit structure design of this technical solution can effectively solve the problem of different button feel at both ends. The master and slave panel structures are the same, and there is no need to distinguish between models, which achieves significant savings in manufacturing costs for manufacturers.

[0047] In practical applications, this technical solution: (1) Utilizing live wire common ground technology, the dual-control C port can easily provide power to the slave panel, eliminating the tedious step of connecting the slave panel to a separate power source. (2) Utilizing the dual-control C port for single-line communication, efficient and stable data transmission is achieved through carefully defined communication frequency and duty cycle. This communication method not only improves the system's response speed but also ensures the accuracy and reliability of data transmission. (3) This design does not require distinguishing between master and slave switches. Through flexible wiring adjustments, each switch can serve as both a master switch and a slave switch.
