Indoor LED intelligent illumination system based on multi-sensor data fusion

Abstract

The invention discloses an indoor LED intelligent illumination system based on multi-sensor data fusion, and belongs to the technical field of indoor illumination. The system comprises a low-power-consumption power supply, a multi-sensor module, a data processing fusion module, an intelligent control module, an LED drive module, an LED lamp, and a wireless communication module. The multi-sensor module collects the data of indoor illumination, person moving and lamp temperature, and transmits the data into the data processing fusion module for preprocessing and feature extraction and recognition, carries out the independent decision of a detected target, carries out the information fusion of all independent decisions through employing a D-S evidence theory, and forms an illumination decision. The intelligent control module generates a corresponding PWM signal according to the illumination decision, and drives the LED drive module to control the adaptive change of the LED lamp. The system generates corresponding illumination control strategies for different indoor illumination demands, improves the illumination effect and comfort, saves the electric energy, and prolongs the service life of the lamp.

Description

technical field [0001] The invention relates to an indoor LED intelligent lighting system, especially based on data collection and fusion of various types of sensors, which can monitor and adaptively control the indoor lighting environment and the working status of LED lamps in real time, and belongs to the technical field of indoor lighting. Background technique [0002] Indoor lighting affects people's daily life, and a good indoor lighting environment can create beautiful lighting effects. At present, about 20% of electricity is used for lighting. LED, as a new lighting source, gradually replaces other types of lamps and becomes a main lighting source due to its advantages of energy saving, environmental protection and long life. LED lamps can be easily digitally dimmed. Taking advantage of this advantage, the intelligent control of indoor LED lighting systems can be realized through electronic technology and computer technology. An intelligent indoor lighting system can...

Problems solved by technology

[0003] In actual use, some LED dimming control systems have appeared, such as timing control of all or part of LED lamps on and off, controlling the switch of LED lamps according to illuminance, or using infrared sensors to detect whether there are people. The effects of these control methods are relatively extensive. There are still problems such as low operational efficiency, high energy consumption, and high investment costs
