摘要
本文剖析了CAN总线和RS-485总线各自的技术特性,结合它们各自的特点,提出了由CAN/RS-485组成的双层网络结构实现户用计量仪表数据远程传输的网络结构设计,并且给出了协议转换网桥的硬件设计和软件流程。实验测试表明,所设计的系统成本较低、可靠性高、扩展性能好、抗干扰能力强,达到了设计要求。
In this paper, the characteristics of CAN bus and RS-485 bus are analyzed, A double level network structure is introduced and the system for realizing the structure of network bridge is given. The practical test shows that this system has the charactern of low-cost, high stability, high expansibility and anti-interference ability.
