Research and realization of LED display system based on combining CAN bus with DMX512 standard

Abstract

With the development of computer and LED technology, the market scale of landscape lighting is expanding rapidly. LED display system based on conventional DMX512 standard has such problems as poor reliability, slow speed, short distance communication, which can not completely meet the increasing demands of the current market. We put forward an integrated communication method that LED system combines CAN bus with DMX512 standard. This proposed method merges above two communication modes, makes full use of each advantage and improves systempsilas reliability, communication speed and distance. The improved method is applied to landscape lighting in Shanghai Global Financial Center (the highest building in the world), which can realize a new LED system with long distance, high speed, fully dependable communication and create special lamps according to the building design. The new system has already been used in this highest building and achieved enormous potential ability of the market.
