基于自组网技术的燃气无线抄表系统研究

摘要

In order to solve the problem of unstable wireless network, complex routing protocol, weak self-repair capacity and so on in data acquisition and transmission in gas wireless meter reading system, a tree topolo-gy wireless ad hoc network system based on wireless communication chip CC1101 is proposed and designed. This paper. mainly conducts research and design in Routing protocols of data acquisition layer and hardware in the system, analyzes the differences between the wireless meter reading system and the traditional wireless meter reading system and designs the network transmission protocol and the whole structure of the data collection layer . Communication between wireless nodes works in 433 MHz Band under strong penetrating power, which can guarantee the stability and speed of Ad Hoc network.%为解决现阶段燃气无线抄表系统数据采集中无线网络不稳定、路由协议复杂、自修复能力薄弱等问题，提出并设计了一种基于cc1101无线传送模块的树形拓扑结构无线自组网系统。系统中主要对数据采集层路由协议和硬件实现进行了研究和设计，分析了该燃气无线抄表系统与传统燃气无线抄表系统的不同之处，设计了该系统数据采集层网络传输协议和总体结构。无线节点建在穿透力强的433 MHz的频率下进行通信，保证了系统自组网的稳定快速。
