摘要
基于ATmega128L的主从式控制器结构的LonWorks列车智能电表,采用高精度三相电能计量芯片ATT7022A作为测量器件,通过ShortStack方式方便地在电表上增加LonWorks网络接口。并介绍该智能电表的硬件结构、功能及软件设计。
A kind of train intelligent power meter is introduced here. This power meter is based on a master-slave controller by using ATmega128L and Neuron chip. It chooses a high precision three-phase energy metering IC ATT7022A as measuring device and add LonWorks interface to the meter by means of ShortStack. In this paper the structure of hardware, functions and software design have been introduced in detail.
