LED industrial lighting wired remote intelligent multi-channel dimming control method

Abstract

The invention discloses an LED industrial lighting wired remote intelligent multi-channel dimming control system and method. The LED industrial lighting wired remote intelligent multi-channel dimmingcontrol system comprises a microcontroller, a PWM duty ratio display module, a man-machine interface module, a PWM open-drain output module, a PWM receiving module and a power adapter. The microcontroller displays a PWM duty ratio value on the PWM duty ratio display module according to the PWM data subjected to intelligent conversion processing according to the instruction information sent by theman-machine interface module; and meanwhile, according to the PWM duty ratio and a control instruction, the PWM open-drain output module and the PWM receiving module are used for controlling a plurality of LED driving power supplies contained in the PWM receiving module, so that dimming or turn-off of a plurality of LED lamps is realized. The multi-channel dimming control system has the advantagesthat remote transmission of PWM signals is reliable and stable, interference is avoided, the lamp coverage is wide, dimming and turn-off of the multi-channel dimming turn-off control system are achieved through an intelligent digital control mode, and the multi-channel dimming control system can meet the industrial or commercial intelligent energy-saving lighting requirements.

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 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 of civil buildings. At the same time, wireless technologies such as zigbee and Z-wave are becoming more and more common in smart home lighting. However, there are relatively few product technologies in terms of industrial lighting intelligence. [0003] The industrial lighting environment is relatively harsh. For example, the height and spacing of various machinery and equipment are different, and various factors such as the steel structure of the ceiling chandelier environment and unstable temperature and humidity are not easy to insta...

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.
