基于RF的无线抄表系统设计

A Design of Wireless meter reading system based on RF

在分析目前无线抄表使用的主要技术基础上,结合目前规划智能电网和智能电表的大量需求,提出一种基于RF无线芯片和RS-485通信标准的无线抄表系统,在不改动传统仪表的工作方式的条件下,为传统仪表加上数据采集模块、中继模块和汇聚模块,通过RF无线传输模块构建通信网,制定了相应的通信协议,进行中继通信,扩大传输距离,实现了远程无线抄表的功能,该抄表系统硬件电路简单、成本低廉、操作简单;通过实验测试,所设计的无线抄表系统性能良好,具有广泛的应用前景。

This paper based on the analysis of the main technologies of the current wireless meter, propose a new scheme of the wireless meter , which isn＇t need to change the works of the traditional instruments, just as traditional instruments combined with data acquisition, relay and convergence module, this module can set up communication network by RF wireless data transmission module, relay communication, expand the transmission distance, to implement the features of the remote wireless meter reading function.
