摘要
由于我国现代电子科学技术的迅速发展,电力网络仪表日益趋于智能化和网络化[1]。为了实现电力网络仪衰的实时监控,仪表的接口设计显得尤为重要。Modbus协议以其高效性,可靠性,广泛应用于电力行业[2]。本文设计了一款以ARM Cortex-M3微控制器为核心,基于MODBUS通信协议的电力网络仪表通信接口。
With the rapid development of electronic science and technology, power meter is becoming more and more intelligent and networking, In order to realize the remote monitoring in real time, the design of instrument interface has become an important task. For this reason, I designed a powerful communication interface with a simple structure based on MODBUS-protocol using a ARM Cortex-M3 MCU. This article introduces the principle and working method of this design.
