Description

Technical Field

[0001] This invention relates to the field of smart home technology, and in particular to the intelligent control of home lighting systems. Specifically, it is an IoT-based intelligent control system for home lighting, built upon Internet of Things (IoT) technology, artificial intelligence algorithms, and energy-saving and environmental protection concepts. The system aims to provide a system that can automatically adjust the lighting status according to environmental changes, objective requirements, and user-defined needs. Background Technology

[0002] With the advancement of technology and the improvement of living standards, smart homes have become an important lifestyle choice for modern families. Among these, intelligent lighting systems, as a key component, directly impact the residents' living experience. Traditional home lighting systems mostly rely on manual switches and cannot automatically adjust lighting based on ambient light, user behavior, or time of day, failing to meet the modern family's pursuit of a high quality of life. Therefore, developing a smart home lighting control system that can automatically adapt to environmental changes, adjust lighting intensity and color temperature according to user habits, and also features remote control and energy-saving capabilities is particularly important. Summary of the Invention

[0003] To address the current situation, this invention provides an intelligent home lighting control system aimed at improving the intelligence of lighting control and meeting diverse user needs. This invention proposes an IoT-based intelligent home lighting control system, including a router, an IoT gateway (server), a touch control panel, a human body sensor, a light sensor, a dimming controller, and LED lighting equipment. The router connects multiple networks (LAN, Internet) to enable communication between different networks; the IoT gateway (server) acts as a bridge between IoT devices and the management terminal, distributing control commands from the management terminal; the touch control panel operates and controls the LED lighting equipment and integrates a voice recognition module; the LED lighting equipment provides illumination to meet people's lighting needs in different scenarios; the human body sensor uses radar waves to detect the presence and movement of people; the light sensor detects the intensity of light in the environment; and the dimming controller receives commands to adjust and control the brightness of the LED lighting equipment. The voice receiver converts voice signals into digital signals and performs filtering, amplification, and other processing.

[0004] The IoT gateway (server) is bidirectionally connected to the router, communicating using the standard TCP / IP protocol. The gateway (server) provides services to the management terminal and receives instructions from it through the router. The gateway (server)'s input terminals are connected to the output terminals of the human body sensor, light sensor, and dimming controller, communicating using the standard Modbus protocol. It collects real-time status data from the human body sensor and light sensor and converts it into standard digital signals.

[0005] The touch control panel has its output end connected to the input end of the IoT gateway (server) and communicates using the standard Modbus protocol to transmit control commands to the IoT gateway (server) for execution.

[0006] The dimming controller has its input terminal connected to the output terminal of the gateway device and communicates using the standard Modbus protocol. The microcontroller of the dimming controller receives control commands from the gateway, and the output terminal of the dimming controller is connected to the input terminal of the LED lighting device. By changing the duty cycle of the current and voltage output to the LED lighting device through pulse width modulation, the dimming controller realizes digital control of the switching and light intensity of the LED lighting device.

[0007] The voice receiver's output is connected to the input of the IoT gateway (server). It communicates using the Modbus protocol. The voice receiver performs preprocessing such as noise reduction, filtering, and enhancement on the received user voice commands, converts them into digital signals, and transmits them to the IoT gateway (server) through a digital interface. The IoT gateway (server) parses and recognizes the data and issues response commands according to the system's preset scenarios.

[0008] Through the above technical solutions, the present invention achieves intelligent control of LED lighting equipment in three ways, the specific intelligent control methods are as follows.

[0009] Method 1, Automatic Control: First, the IoT gateway (server) collects key information such as the presence of people indoors detected by the human body sensor and the light data from the light sensor in real time. The system analyzes and processes this data through a light sensing algorithm based on multiple parameters such as the presence of people, light intensity, and time. According to the system's preset rules and strategies, it generates control commands to change the voltage and current, and sends the commands to the dimming controller through the IoT gateway (server), thereby achieving precise control of the LED lighting equipment.

[0010] Method 2, Remote Control: This invention provides an APP and a web management terminal, allowing users to remotely control LED lighting equipment through the APP and web page.

[0011] Method 3, manual and voice control: This invention allows manual control of LED lighting equipment via a touch control panel, while also supporting voice control. Users can preset various intelligent lighting scenes in the system, such as home mode, away mode, and movie mode. Users only need to speak the corresponding command, and the system will automatically adjust the relevant equipment to the preset state to achieve scene linkage. Attached Figure Description

[0013] Figure 2 This is a functional schematic diagram of the home lighting intelligent control system in an embodiment of the present invention. Detailed Implementation

[0014] To further understand the invention's content, features, and effects, a detailed description is provided below in conjunction with the accompanying drawings.

[0015] The present invention will now be described in detail with reference to the accompanying drawings.

[0016] See Figure 1 , Figure 2 This invention provides an IoT-based smart home lighting control system, comprising an IoT security gateway (server), a voice recognizer, a touch control panel, a human body sensor, a light sensor, a router, a management terminal, LED lighting equipment, and a dimming controller. First, the human body sensor and light sensor are deployed in key indoor areas. The human body sensor detects the presence of people in real time, while the light sensor monitors parameters such as indoor light intensity, light direction, and the rate of change of light intensity. The IoT security gateway (server) collects the data from the human body sensor and light sensor in real time. The system analyzes the data collected by the IoT security gateway (server) in real time. By analyzing the presence of people and combining preset values, the system can turn off the lighting equipment if no one is in the room for more than five minutes, or turn on the lighting equipment when someone is detected entering the room. Using a light sensing algorithm, the system comprehensively considers core parameters such as light intensity, light direction, and the rate of change of light intensity, and combines multi-dimensional information such as light source characteristics, indoor environment, lighting needs, and time factors to accurately calculate the appropriate light intensity for the room. Simultaneously, the system generates corresponding control commands based on the calculation results. The dimming controller automatically adjusts the duty cycle of voltage and current according to the required indoor light intensity, enabling automatic control of lighting equipment in different scenarios. It also features overvoltage and overtemperature protection measures.

[0017] Furthermore, a web application service (server) with monitoring and control capabilities is deployed on the IoT security gateway and provided for external access via a router. This server includes four modules: a data acquisition module, a data analysis module, a device control module, and a lighting module. The data acquisition module collects real-time data on human presence and indoor illuminance, allowing users to view the collected data. The data analysis module analyzes the required indoor light intensity using a light-sensing algorithm and determines whether lighting is needed based on human presence. The device control module controls the power supply to the lighting equipment and the light intensity of the lighting equipment. The lighting equipment module, as the foundation of the system, stores LED lighting equipment information digitally within the system, enabling monitoring and control of the lighting equipment based on this information. This invention provides an APP and a web management terminal, allowing users to easily remotely control and manage LED lighting equipment. Specifically, users can not only freely adjust key parameters such as brightness and on / off status of LED lighting equipment, but also flexibly set advanced functions such as timed on / off switching and scene mode switching according to actual needs. Whether you want to create a warm and comfortable home atmosphere or pursue an energy-efficient office environment, users can instantly adjust to their ideal lighting state with a simple touch of their fingertips.

[0018] Furthermore, this invention integrates both manual and voice control support on top of remote control. Users can directly and precisely adjust various parameters of the LED lighting equipment, such as brightness and on / off status, via the touch control panel. Simultaneously, voice recognition technology is introduced. First, the user's original voice is recorded in the system. Then, the voice recognizer captures the sound signal, converts it into an electrical signal, and the system extracts voice features, comparing them with the recorded original voice in terms of spectrum, waveform, pitch, and intensity. If a match is successful, the system converts the human voice into recognizable commands. Based on various preset personalized intelligent lighting scenes, such as home mode, away mode, and movie mode, seamless switching and linkage between scenes are achieved.
