Field bus control system for intelligent light-emitting diode (LED) lamp

Abstract

The invention provides a field bus control system for an intelligent light-emitting diode (LED) lamp. The field bus control system at least comprises a master controller and a plurality of slave controllers, wherein the slave controllers comprise a first slave controller, a second slave controller, ..., an (N-1)th slave controller and an Nth slave controller; a signal wire of the master controller is at least directly connected to the first slave controller, the second slave controller or / and the next slave controller; and a signal wire of one of the slave controllers is at least directly connected to the next slave controller or / and the second next slave controller or / and the third next slave controller adjacent to the controller. The field bus control system aims to solve the problems of difficulty in management, limitation to a communication distance, low fault tolerant capability and the like of an LED field control bus in the prior art.

Description

technical field [0001] The invention relates to the field of system control of LED lamps, in particular to a field bus control system for LED intelligent lamps. Background technique [0002] LED has attracted more and more attention due to its high luminous efficiency, good color rendering, long service life, high reliability, easy control and multi-color features. As a symbolic symbol of a city, street lamps have gradually become a landscape of the city. , especially recently, more and more countries have formulated energy-saving emission reduction regulations and lighting standards, which has more effectively promoted the development of the LED smart lamp market. [0003] However, with the rapid development of the LED lighting market, the LED smart light market has become a major focus for companies to compete for share. Due to the lag in the development of authoritative technical standards, the entire LED smart light industry is uneven. Looking at the current wired networ...
