Aiming at the wired and mechanical control methods of traditional lighting, this paper proposes an LED intelligent lighting control system based on Internet of Things (IoTThings, IOT) technology, embedding intelligent control module into LED lighting terminal, comprehensively using embedded technology, wireless sensor network, etc. The technology realizes intelligent, digital and wireless intelligent lighting control methods, and also has monitoring functions of environmental parameters such as ambient temperature and humidity and illuminance.
Overview
With the increasing popularity of LED lighting and the rapid development of mobile Internet technology, people are increasingly demanding the networking, intelligence, and energy saving of home life, and adopting wireless devices such as household appliances, lighting fixtures, and security alarms. Integrated into the control platform for intelligent control and intelligent management.
With the development of the Internet of Things (IOT) industry, smart LED lighting has become an important part of IOT.
This article provides intelligent LED lighting control system for the implementation of "Green Smart Lighting", using Internet of Things technology, embedded technology, etc. to realize wireless remote control of various lighting modes of LED lamps, and within the working range of LED lamps Ambient illumination and LED lamp working status are monitored in real time. At the same time, sensor technology is used to realize adaptive illumination adjustment of LED illumination and various combinations of light color conversion, thereby creating a comfortable, energy-saving and safe light environment. Figure 1 shows:
System hardware design
The hardware design of the system includes LED lighting control terminal and touch panel, which are used to realize intelligent lighting control of LED lamps; mainly include control module, communication module, LED driver module and power module.
(1) Hardware design of the main control unit
The main control unit of LED intelligent lighting control system is composed of two main parts: LED lighting control terminal and data acquisition terminal. The LED lamp control terminal is composed of ARM processor STM32 as the control core, which is composed of power supply circuit, peripheral circuit and illumination sensor. The data acquisition terminal is composed of temperature and humidity sensor, illuminance sensor and PM2.5 sensor. The schematic diagram of the hardware circuit is shown in Figure 2. Shown.
