摘要
RS485总线常用来实现远程信息交互。该文介绍了基于RS485的分布式LED显示系统。对系统简单描述后,文章详细介绍了系统的硬件和软件设计实现过程,并对RS485的组网提出了建议,提供了一种低成本、结构简单的分布式LED屏实时显示系统解决方案。该系统在清远某玻纤公司称重显示系统得到成功实现。
RS485 bus is usually used in telecommunication. This paper introduced a distributed LED showing system based on RS-485 bus. After simply describing the the system, the paper introduced the design detail of hardware and software, and give advice to the RS485 bus, It’s a low cost, simple structure solution to the distributed LED showing system based on RS485 bus. The system was applied in a weight system in a QingYuan class corporation successfully.
