针对470 MHz～510 MHz频段内越来越广泛的低功耗、低成本的无线集中采集系统应用.该文设计了一种基于ARM Cortex-M0微控制器,具有实现自组网,自动路由,节点自动跳频功能的无线终端模块.详细介绍了系统的主要结构,模块的硬件和软件设计,详细阐述了自组网和自动路由的原理和实现方法.设计中实现了自组网、自动路由、自动绑定地址等功能.应用证明,该系统可以应用在无线抄表、安防、智能家居、无线传感器网络等多种中短距离系统中,性价比高,稳定可靠.%For more extensive use of low-power 470MHz~510MHz frequency, low-cost wireless centralized acquisition systems. This paper introduces a design based on ARM Cortex-MO micro controller,with will be able to realize the Ad hoc network,automatic routing,node to be automatic frequency hopping function of the wireless terminal module. Introducing the main structure of the system,the design of hardware and software modules,and expounds the principle and realization method of Ad hoc network and automatic routing. The design realized the functions of networking, automatic routing,automatic binding address and other. Application shows that the system can be applied in wireless meter reading,security,intelligent household,wireless sensor networks and many kinds of medium distance systems,cost-effective,stable and reliable.
