R & D

SUNPN has one software & hardware engineers team with rich experience, in view of customers different demand, develop corresponding function product. Meanwhile constantly update and innovation  product cases, add new science technology to make product more safe, more stable, and more convenient. Our company  own complete independent intellectual property rights, and we obtained major breakthrough on gas sign digit display control side in 2013, got innovation technology patent of gas sign digit display RS485 differential signal control system .




Invention Content

To level signal long distance transmission are susceptible to interference question, this new type invention adopt single chip micro controller to alonely control each segment digit, then use main control card to control each segment digit display through inner protocol, use RS485 differential transmission way(DTR) between segment digit to segment digit, and control card to control card, greatly improved the signal transmission distance and stability, at the same time, flexible inner communication protocol ensures the synchronization effect.

Invention Effect

Through using above LED segment type display way, greatly improved the signal transmission distance, make display signal cable length be extended to 1 km between digit to digit and control card to control card in one sign, markedly improve signal stability, effectively restrain the sign flash etc unnormal question,at the same time, simplify the connecting between display digit and control card, between display digit to display digit can be parallel wiring, series wiring as well, no limit.
