Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more features. In the description of the utility model, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0028] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] like Figures 1-2 As shown, the distributed control whole-house lighting system based on G3-PLC communication proposed in this utility model includes multiple LED lights, a gateway controller, an LBS (Low-Based Service) of model LC850, multiple LBDs (Low-Based Lighting) of model LC850, and multiple LED controllers, wherein:

[0030] Multiple LED lights are positioned in different locations indoors to provide illumination, featuring adjustable brightness and color temperature. The G3-PLC communication system uses two devices: LBS and LBD. The LBS is installed at the gateway, and the LBD is installed on each LED light. The LBS manages and maintains the entire G3-PLC communication system and can communicate with each LBD. In addition to communicating with the LBS, the LBD must also output PWM to control the LED brightness. The gateway sends a scene description to the LBD, which automatically adjusts the light brightness accordingly. The gateway can send commands to the LBD via unicast, multicast, and broadcast. The gateway can also read the LED's voltage, current, and power from the LBD. The gateway controller is connected to the LBS for control, the LBS to the LBD for communication, the LBD to the LED controller for control, and the LED controller to the LED lights for control. The LBS has a PLC transceiver a, and the LBD has a PLC transceiver b. The LBS and PLC transceiver a are connected for control, and the LBD and PLC transceiver b are connected for control. PLC transceiver a and PLC transceiver b are also connected for communication.

[0031] To facilitate observation of the working status of LBS and LBD, this utility model includes a communication indicator light a on the LBS, which is electrically connected to the communication indicator light a, and a communication indicator light b on the LBD, which is electrically connected to the communication indicator light b. In this way, the operator can determine the working status of the G3-PLC communication system by using the communication indicator lights a and b.

[0032] Based on the above embodiments, an ambient light sensor is also included. An ambient light sensor is installed on the LBD. The ambient light sensor is used to detect the ambient light intensity in real time and send the detection data to the LBS through the PLC transceiver b. The LBS generates a corresponding control signal based on the received ambient light intensity data and the preset brightness adjustment strategy and sends it to the LBD. The LED controller then automatically adjusts the brightness of the LED lights according to the control signal to maintain the comfort and stability of indoor lighting.

[0033] Furthermore, it also includes a self-test module, which is installed on the LBS, LBD, and LED controller. By setting up the self-test module, the system can monitor its own working status and communication status in real time. When a device fault or communication abnormality is detected, the self-test module feeds back the fault information to the LBS through the PLC transceiver. The LBS then reports the fault information to the gateway controller. The gateway controller takes corresponding recovery measures based on the fault information, such as attempting to resend control signals, switching to a backup communication channel, or prompting the user to perform equipment maintenance, to ensure the normal operation of the lighting system.

[0034] Furthermore, it also includes a network communication module. The gateway controller is equipped with a network communication module that communicates with the user's mobile terminal device via the internet. The user can remotely send lighting control commands to the gateway controller through an application on their mobile terminal device. The gateway controller then performs the corresponding control operations according to the commands, enabling the user to remotely control the whole-house lighting system and conveniently control indoor lighting from different locations.

[0035] In summary, this application uses G3-PLC communication technology instead of Bluetooth technology, avoiding the unreliability of communication caused by the increase of Bluetooth nodes and the impact of obstacles on communication performance. Power lines, as a widely distributed and stable communication medium, and the G3-PLC communication protocol with strong anti-interference capabilities and error correction mechanisms, ensure stable data transmission between the gateway controller and each LED light, guaranteeing the accurate issuance of lighting system control commands. Users can remotely send lighting control commands to the gateway controller via the internet through an application on mobile terminal devices (such as mobile phones and tablets), regardless of their location. This allows users to turn on the lights in advance before returning home, or check and adjust the lighting status when away from home, providing great convenience and enhancing the smart home user experience.

[0036] Working principle: such as Figure 2 As shown, LBS and LBD constitute the communication network of G3-PLC. The gateway sends commands to each LBD or LED through LBS to control the brightness or color temperature of the LED. LBS manages and maintains the G3-PLC network, ensuring communication reliability. PLC communication is not spatially limited because signals are transmitted via power lines. Since HPLC is widely used in centralized meter reading systems, its use indoors would affect these systems. Because G3-PLC is not used in centralized meter reading systems in China, its use for indoor lighting control will not affect these systems. Furthermore, G3-PLC also uses OFDM communication technology with a communication rate of up to 300K, ensuring reliable communication and fully meeting the needs of lighting control.

[0037] Furthermore, the LC850 in this invention features an M4 core, operates at 150MHz, and has a built-in G3-PLC baseband PHY interface. The G3-PLC has a communication rate >300Kbps in FCC mode, a maximum operating speed of 150MHz, 2Mbyte FLASH, 2Mbyte SRAM, 7 UARTs, 3 SPIs, 2 I2Cs, an Ethernet RMII interface, a PLC MAC / PHY interface, 4 timers with PWM output, 53 GPIOs, a built-in 3.3V to 1.2V converter, and an operating temperature range of -40℃ to +85℃. A built-in independent WDG ensures stable and reliable system operation. Power management provides a stable DC 3.3V power supply for stable system operation. The built-in G3-PLC baseband PHY interface receives and transmits G3-PLC carrier signals via a PLC transceiver. The LC850 outputs PWM signals to adjust the brightness of the LEDs and communicates with the LED controller via a serial port. The gateway controller communicates with the LBS via a serial port, and sends commands to the indoor LED lights through the LBS. The communication indicator LEDs display the communication status of the carrier.

[0038] Through our technicians' practical experience, we have found that the following issues should be noted during the production and installation of LBS and LBD:

[0039] 1. After installation indoors, the gateway needs to be configured for it to work.

[0040] 2: LBDs must be configured with a unique device address at the factory.

[0041] 3: After installation, the gateway needs to register the device address of each LBD.

[0042] 4. The gateway needs to group LBDs and configure scenarios.

[0043] 5: Users can control the lights via the gateway using unicast, multicast, or broadcast.

[0044] 6. It allows indoor lights to be used in various application scenarios.

[0045] 7. The gateway can monitor the operating status of each light and promptly identify any light malfunctions.

[0046] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
