Description

Technical Field

[0001] This invention relates to a multimodal interactive intelligent lighting control system, belonging to the technical field of intelligent lighting control systems. Background Technology

[0002] In recent years, with breakthroughs in IoT, AI, and wireless communication technologies, smart lighting systems are transforming from basic functions to personalized and intelligent solutions. Technologies such as dynamic dimming and color changing have been applied to urban landscapes, commercial advertising, and home settings, significantly enhancing spatial artistry and interactive experiences. However, existing systems largely rely on mobile apps or voice control. While they support preset modes (such as fade / flicker) and parameter adjustments, they still suffer from cumbersome interaction, insufficient device compatibility, and limited scene adaptability, failing to meet the modern family's demand for flexible, intelligent, and personalized lighting.

[0003] Existing lighting control systems largely rely on manual switches, remote controls, or timers, lacking intelligent management and the ability to integrate with other smart devices. Their control methods are simplistic and inconvenient, and they cannot dynamically adjust lighting according to different scenarios. Furthermore, although LED lighting is gradually replacing traditional lighting equipment due to its energy-saving, high-efficiency, and long-life advantages, existing LED control systems still suffer from limited control distance, limited functionality, and the inability to achieve remote control, failing to truly provide users with a convenient and efficient intelligent lighting experience. Summary of the Invention

[0004] Therefore, it is necessary to address the problems existing in the above-mentioned lighting control systems by providing a solution that integrates multiple control methods such as wireless communication, voice recognition, and remote control buttons. This solution would allow users to flexibly control lighting with different effects through wireless remote control, voice assistants, and other means, meeting the lighting needs of different scenarios. Furthermore, it would have the ability to interact with other smart devices, thereby improving the overall level of intelligence and promoting the development of smart lighting technology.

[0005] In a first aspect, this application provides a multimodal interactive intelligent lighting control system, comprising the following steps: The mainboard of the lighting system includes a main control module, a lighting module, an OLED module, and a communication unit (WIFI module, wireless module receiver, and voice module).

[0010] In the description of this application, it should be noted that the terms "1" and "2" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, the term "core" is used only to describe the importance of the portion within the device and does not imply that the portion is located at the center of the device.

[0011] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, the TCP connection establishment phase implements triple protection: a fixed target address of 192.168.4.2:8080, a three-way handshake retry mechanism, and automatic activation of the transparent transmission mode; special mode 7 activates the network connection counter, while other modes forcibly reset the communication flag. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0012] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0013] (a) Implementation of the main lighting control system board like Figure 2 As shown in the figure, this application discloses a multimodal interactive intelligent lighting control system, the specific implementation process of which includes: This device uses the main control system board as the core of lighting control, integrating a multi-modal control interface and a dynamic lighting effect engine to construct a three-layer control architecture. The hardware layer employs an STM32F103 series microcontroller, implementing three-channel LED driving via the GPIOA port. The push-pull output mode ensures a 20ns response time at a 50MHz rate, and an initial high-level configuration avoids power-on surges. Independent control of PA1-PA3 forms the basis for combined lighting effects, with direct register manipulation during mode switching to achieve μs-level state transitions. The lighting effect algorithm layer is divided into static and dynamic categories: the basic modes 0-3 achieve single-lamp, dual-lamp, and full-brightness control through level combinations; the dynamic mode uses a software simulation strategy, with flowing light effects sequentially activating PA1-PA3 pins at 100ms intervals, and duty cycle adjustment achieving linear gradation from 0-100 levels. The flashing mode generates a 50% duty cycle square wave, with the frequency adjusted by parameter H. The state management layer implements a dual-path synchronization mechanism. The OLED partial refresh technology only updates the hexadecimal mode display area. In the interrupt response design, each light effect loop is embedded with a HandleCommand() call to ensure that external instructions are responded to within 50ms. When an abnormal exit occurs, the LED state is forcibly reset to prevent light effect residue.

[0014] The network communication module constructs a dual-mode control channel. The ESP8266 is configured in AP mode, and the SSID "ESP8266" uses WPA2-PSK encryption. A pre-configured address of 192.168.4.1 is used to avoid IP conflicts. Triple protection is implemented during the TCP connection establishment phase: a fixed target address of 192.168.4.2:8080, a three-way handshake retry mechanism, and automatic activation of the pass-through mode. The instruction processing system implements priority arbitration. When the WiFi channel parses text instructions, it immediately returns an "OK" confirmation packet. LED status queries generate real-time reporting data through polling GPIO. The NRF24L01 wireless channel directly reads the first byte of the buffer to update mode, and dual-channel data is synchronized on the OLED screen. The exception handling module is designed with self-healing logic. Network interruption triggers the Shu counter to accumulate. After three consecutive communication failures, it automatically switches to wireless control mode. The pass-through exit sequence "++" ensures a safe reset of the protocol stack.

[0015] The voice control module drives I²C communication via an external interrupt, with data reception triggered by the PA7 pin detecting the start condition. It strictly adheres to standard timing: the address byte verifies the 0x3C device identifier, and the data byte directly maps to the mode command. Special mode 7 activates the network connection counter, while other modes forcibly reset the communication flag. The interrupt service routine completes address matching and data parsing within 10μs, and the hardware filtering mechanism effectively isolates bus interference. The three-layer architecture achieves microsecond-level response, but there is a risk of missing verification; this can be upgraded to CRC checksum + retransmission mechanism to improve reliability.

[0016] (ii) Implementation of the wireless controller like Figure 3 As shown in the figure, this application discloses a multimodal interactive intelligent lighting control system, the specific implementation process of which includes: The controller uses an STM32F103 as its processing core, constructing a dual-function system for human-machine interaction and command relay. The input system implements an analog signal partitioning strategy; a 12-bit ADC quantizes the physical travel into a value range of 0-4095, with the edge 10% (≤100 / ≥4000) designated as the effective trigger zone and the middle 90% as a dead zone for anti-jitter. The XYZ axes are mapped to ±1 / 0 digital signals, with a 100ms fixed delay window to suppress mechanical jitter. Although this results in a 300ms periodic delay, it ensures operational determinism. The menu navigation engine uses a circular index model, with a global variable T1 recording the focus positions of items 0-7. X-axis input drives T1 to increase and decrease in a circular manner, while the Y-axis has a reserved expansion interface. The visual feedback system implements layered rendering: the base layer preloads 8 menu icons, the dynamic layer draws an "OK" confirmation icon in real time, the focus layer highlights the current option with an inverted color block, and local refresh technology controls the OLED update area to 80x16 pixels, with a refresh time of <50ms.

[0017] The execution phase involves three atomic operations: clearing the history prompt area to avoid information overlap, displaying "OK" feedback horizontally centered at 56 pixels, and updating the inverted focus using the Menu_Area function. The data communication layer encapsulates an 8-byte buffer, with the first byte storing the mode number. The NRF24L01 transmits at a rate of 2Mbps, and a 1-second state lock prevents command overload. The spatial layout uses a four-row static window, with the Y-axis coordinate dynamically calculated as (T1%4+1)*16. The scrolling mechanism supports 8 menu items, but the lack of a pagination indicator negatively impacts user experience. The core process comprises a 200ms operation cycle: 100ms input detection + 50ms interface refresh + 50ms communication processing, ensuring data encapsulation and transmission are completed within 3ms at a 2Mbps rate.

[0018] The system design offers two levels of optimization: at the hardware level, an encoder can be added to achieve stepless scrolling; at the software level, a state machine can be used to replace blocking delays. The current architecture implements basic functions on low-cost hardware, but suffers from interaction continuity defects. Future updates can improve smoothness by using a non-blocking timer and double-buffered display. The communication protocol urgently needs enhancements to verify fields and serial numbers to cope with interference in industrial environments. In a typical application scenario, the operator selects mode 4 (flowing light effect). After confirmation, the controller sends the 0x04 command. Upon receiving this command, the main control board activates a sequential scan of PA1-PA3, and the OLED display updates synchronously, forming a complete closed-loop control.
