DETAILED DESCRIPTION

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1-5As shown, this embodiment includes six compatible components: a PLC main control 1, a PLC transformer 2, a PLC connector 3, a PLC gateway 4, and a PLC floor-mounted light 5. The PLC main control 1 consists of a power driver module, a PLC module, an illumination module, a display module, a key module, and an MCU module, enabling simple human-computer interaction and controlling the light string. The power driver module connects to and supplies power to the illumination module, display module, key module, and MCU module, respectively. The MCU module also connects to the PLC module, illumination module, display module, and key module for signals. All of these connections are made via an AC line. The power driver module converts the incoming AC line (12V) to DC3.3V and supplies power to the illumination module, display module, key module, and MCU module. The PLC module operates by connecting to the AC line (12V). The PLC module primarily performs modulation and demodulation. After receiving signal data from the MCU module, the PLC module modulates it into the AC line for transmission to other devices. Once the PLC module demodulates the data from the AC line, it transmits it to the MCU module. The illumination module converts illumination into a voltage for the MCU module to collect through an illumination diode and a voltage divider resistor. The display module consists of an indicator light and a digital display. The indicator light indicates the current operating mode of the light string; the digital display primarily displays the time and coordinates the light string operating mode. The key module has five pre-set buttons: MENU, UP, DOWN, ENTER, and RESET. Each button's action converts high and low voltage levels and transmits them to the MCU module. The MCU module primarily implements a real-time clock, collects illumination, and uses keystroke information to set the operating mode and control the light string. Several operating modes are available: 1) TIMEON / OFF mode, which turns the light string on and off at a scheduled time; 2) PHOTOEYEON / TIMEROFF mode, which turns the light string on and off at a scheduled time (darkness); 3) PHOTOEYEAUTO mode, which turns the light string on and off based on illumination (dusk on, dawn off); and 4) MANUAL mode, which turns the light string on and off manually.

[0019] like Figure 2As shown, PLC transformer 2 consists of a PLC module, a transformer module, and a switch module. It integrates the transformer with the PLC master control 1, primarily performing the functions of converting AC power to 12V and PLC master control 1. The structure of the PLC module is identical to that of the PLC master control 1. The transformer module connects to the external AC power supply and outputs operating power to the PLC module and power driver module within the PLC module. The switch module is located between the power driver module and the transformer module within the PLC module to control the on / off of both. The switch module receives high and low voltage levels from the MCU module pins to control the on / off of the AC line (12V). The PLC module has the same functions as the PLC master control 1, but also adds an output to disconnect the AC line (12V). The transformer module can convert AC power to 12V, powering the light string.

[0020] like Figure 3 As shown, the PLC connector 3 is composed of a power driver module, a PLC module, a floor lamp driver module, and an MCU module. Through the PLC connector 3, an ordinary floor lamp can be modified to be able to be controlled over the Internet, and remote control and synchronous switching of the light string to adjust the brightness can be achieved. The power driver module is connected to the MCU module and supplies power, and the MCU module is respectively connected to the PLC module and the floor lamp driver module signal. The floor lamp driver module mainly receives the PWM of the MCU module and supplies power to the ordinary floor lamp according to its duty cycle, and controls its switching and brightness by phase-cutting dimming. The MCU module can receive instructions from the PLC module and output PWM with different duty cycles to the floor lamp driver module according to the instructions.

[0021] like Figure 4 As shown, the PLC floor lamp 5 is composed of a power drive module, a PLC module, a light-emitting board module, and an MCU module. It is a floor lamp that can realize linkage control and synchronization of lighting status. The power drive module is connected to the light-emitting board module and the MCU module and supplies power, and the MCU module is respectively connected to the PLC module and the light-emitting board module signal. The power drive module can convert the AC line (12V) into DC3.3V and DC25V to power the MCU module and the light-emitting board module respectively. The light-emitting board module mainly receives the five-way PWM of the MCU module and controls the switching and brightness of the five-way RGBCW lamp beads according to their duty cycle. The MCU module mainly receives instructions from the PLC module, and outputs five-way PWM modules with different duty cycles to the light-emitting board module according to the instructions. Various lighting modes and brightness are achieved with different ratios of the five-way RGBCW PWM of the same light.

[0022] like Figure 5As shown, the PLC gateway 4 consists of a power driver module, a PLC module, a WIFI module, a Bluetooth module, and an MCU module, and can realize the function of remotely controlling the light string through an APP or a mini-program. The power driver module is respectively connected to and powered by the WIFI module, the Bluetooth module, and the MCU module, and the MCU module is respectively connected to the PLC module, the WIFI module, and the Bluetooth module for signal connection. The WIFI module mainly implements WIFI remote control, transmitting the light control instructions of the APP and the mini-program to the MCU module. After the MCU module parses and executes, it transmits the execution results of the light string to the APP and the mini-program. The Bluetooth module mainly implements Bluetooth short-range remote control, transmitting the light control instructions of the APP and the mini-program to the MCU module. After the MCU module parses and executes, it returns the results to the APP and the mini-program. The MCU module mainly implements the parsing and execution of WIFI and Bluetooth instructions, and modulates the specific light control instructions to the AC line (12V) power line through the PLC module for transmission to the other plug-in lamps.

[0023] Example 1.

[0024] like Figure 6 As shown, this embodiment is a conventional floor-mounted light string system modified using the aforementioned components. This conventional floor-mounted light string system includes a PLC master controller 1 and two PLC connectors 3. Specifically, by mounting the PLC master controller 1 on the AC line (12V) and connecting the PLC connectors 3 in series to the AC sub-line of each conventional floor-mounted light, the conventional floor-mounted light string can be enhanced with PLCLinkable functionality, enabling timing control, light sensitivity control, and lighting status synchronization. If a PLC gateway 4 is also mounted on the AC line (12V), the light string can be remotely controlled via an app or mini-program.

[0025] Example 2.

[0026] like Figure 7 As shown in the figure, this embodiment is a PLCLinkable floor-mounted light string system modified using the above components. This floor-mounted light string system includes a PLC transformer 2, a PLC gateway 4, and multiple PLC floor-mounted lights 5. Specifically, each component is mounted on the AC line (12V). The power line carrier of the AC line (12V) enables timing control, light sensing control, remote control via an app or mini-program, and synchronization of the light string's lighting status.
