Wireless dimming and toning intelligent lighting system

Abstract

The invention relates to a wireless dimming and toning intelligent lighting system which comprises a mobile control terminal, a router, an intelligent gateway, and an LED lamp group. A mobile control end is connected to the router through WiFi. The router is connected to the intelligent gateway which is in a two-way wireless communication with the LED lamp group. The intelligent gateway is formed by an RJ45 network interface, a data processing unit, a network chip, a first wireless transmission processing unit. The LAN port of the router is connected to the RJ45 network interface of the intelligent gateway. The data processing unit is a microcontroller unit (MCU) which is connected to the network chip through a parallel bus. The microcontroller unit (MCU) is connected to the first wireless transmission processing unit through a UART series interface. The first wireless transmission processing unit is connected to a second wireless transmission processing unit which is connected to an LED lamp group driving module which is connected to an LED lamp group. According to the wireless dimming and toning intelligent lighting system, the random brightness and color wireless control of light is realized, the system is suitable for various scene lighting, and the system has the advantages of convenience and rapidness, energy saving, environment protection and low cost.

[0002] In recent years, people's demand for intelligent and high-quality life has become increasingly strong, and the requirements for lighting have also continued to increase; traditional lighting systems have cumbersome wiring, poor management scalability, and single lighting effects. In order to avoid a series of problems such as wiring construction, intelligent lighting The system came into being

[0003] The intelligent lighting system is mainly controlled by 2.4G radio frequency technology, including three wireless communication technologies of Bluetooth, WiFi and Zigbee; the existing Bluetooth-based wireless control lighting solution has a simple connection method, a communication rate of 1Mbit / s, and a very long transmission distance. Limited, generally 0.1 ~ 10m, and due to the single connectivity of Bluetooth communication, the number of devices that can be connected to this type of system is very small, which is not conducive to system expansion; while the lighting control system based on WiFi, although the communication rate is 11Mbit / s, the radio wave The coverage and controllable range has reached 100m, but its design is cumbersome and the power consumption is very high, so it cannot be applied to many wireless lighting scenarios that require low energy consumption; at the same time, the networking capability of WiFi is low, and the expansion space is also limited, so it is not suitable for Multi-device large-scale wireless lighting control similar to smart buildings
