Wired remote intelligent multi-channel dimming control method for led industrial lighting

Abstract

The invention discloses a wired remote intelligent multi-channel dimming control system and method for LED industrial lighting, comprising a microcontroller, a PWM duty cycle display module, a human-machine interface module, a PWM open-drain output module, a PWM receiving module and a power adapter ; Described microcontroller according to the PWM data that the instruction information that described man-machine interface module sends out through intelligent conversion processing, displays PWM duty cycle value on described PWM duty cycle display module; Press PWM duty cycle value and control instruction at the same time , through the PWM open-drain output module and the PWM receiving module to control several LED driving power supplies included in the PWM receiving module, so as to realize dimming or turning off of several LED lamps. The advantages are that the invention has the reliable and stable long-distance transmission of PWM signals, without interference, the coverage of lamps is wide, and the multi-channel dimming and shut-off control system performs dimming and shut-off through an intelligent digital control method, which can meet and be suitable for industrial or commercial use. Intelligent energy-saving lighting needs.

Description

technical field [0001] The invention belongs to the field of LED lighting, and in particular relates to a wired remote intelligent multi-channel dimming control system for LED industrial lighting and a lighting control method realized by using the control system. Background technique [0002] LED lighting technology has developed from landscape lighting and road lighting to interior decoration lighting, commercial lighting and industrial lighting for civil buildings. At the same time, wireless technologies such as zigbee and Z-wave are becoming more and more common in intelligent home lighting. However, there are relatively few product technologies in industrial lighting intelligence. [0003] The industrial lighting environment is relatively harsh. For example, the height and interval of various machines and equipment are different, and various factors such as the reinforced structure of the ceiling chandelier environment and unstable temperature and humidity are not easy...

AI Technical Summary

Problems solved by technology

For example, the height and interval of various machinery and equipment are different, and various factors such as ceiling chandelier environment steel structure and unstable temperature and humidity are not easy to install wireless intelligent control equipment.

[0004] Especially in the industrial environment, the lighting wireless control signal is easily affected by the interference of objects during transmission, and the signal attenuation is also large, which cannot make the wireless control equipment operate normally.
