摘　　要：讨论了一个基于 RS4 85总线的单片机对等网络 ,并用 C5 1语言实现该网络。与常用的主从式单片机网络相比 ,对等网络具有数据吞吐量大、节点与节点间可直接通信的优点 ,因此 ,对要求通信量大或节点间需要频繁通信的场合特别适用。A method of design the peertopeer microcontroller network based on RS485 bus are presented in this paper It has been implemented by using Franklin C51 Comparing with the common masterslave network, the peertopeer network has better performance in through put of data and communication ability between the nodes, so it is especially suitable for this application that there are many data to be transmitted between the nodes
