基于IEEE 802.15.4 MAC协议电能量自动抄表系统

Automatic Reading System for Electrical Power Meters based on the Protocol of IEEE 802.15.4 MAC

摘要:

提出了媒体接入控制(MAC)协议下用于自动读取电能量数据的无线总线结构,并在此结构形式上,分析了电能量终端的数据量特点,以及无线信道中影响误码率的因素.通过实际分析给出了适合无线传输的数据帧格式,最后对通信协议和终端的软、硬件进行了设计.

Abstract:

This paper presents an automatic reading system for electrical power meters based on the structure of the media access control(MAC)wireless bus.The data characteristic of electrical power terminals and the factors influencing packet loss rate in wireless channels are analyzed for this structure.The transmission format of the data frame is proposed.Finally,the communication protocol,the terminal software and hardware are designed.
