摘要
探讨了采用现有的无线数传模块实现无线组网的几个难点问题,介绍了目前在工业控制场合中常用的一种无线网络拓扑结构.并在无线数传模块的硬件平台上,设计了一种适用于该拓扑结构的无线网络协议.重点对网络编址、冲突避免、出错重传/超时重试等方面的设计思路进行了阐述,给出了设计所用的状态图以及为提高系统稳定性而采取的软件方面的措施.
This paper presents some difficulties in wireless network organization with present wireless digital-transportation modules,introduces a kind of wireless network topology which is widely used in industry control system.Based on the hardware platform of the wireless digital-transportation module,this paper puts forward a kind of wireless network protocol which applies to the network topology mentioned,expatiates some design thoughts on network address organization,collision avoiding,error-retransfer and timeout-retry,and also provides the state-diagram for design and some software ways to enhance the stabilization for the system.
