摘　　要：根据配电网对电参数采集和传输的需求,设计了一种基于STM32和Modbus协议的对电力参数进行数据采集、处理和传输的实用性较高的电参数采集系统。介绍了STM32、RS485通讯及Modbus协议,并给出了采集系统的工作原理、软硬件设计和功能实现方法。系统主要是为了提高电参数采集系统的实时性和可靠性,为配电系统电参数的实时采集与传输提供了一种实用的联网技术方案。确实增加了数据采集系统的实时性与稳定性,对目前电参数采集系统的发展起到了推动和促进作用。Aiming at the demands of electric parameter acquisition and reliable data transmission in distribution net- work,an electric parameter acquisition system based on STM32 and Modbus protocol was designed in this paper. The paper introduces STM32,Modbus protocol and RS-485 communications.It also presents the working principle,software and hardware design of the acquisition system and function realization. The new electric parameter acquisition system was to improve the real-time and reliability of the electric parameter acquisition. The practical application shows that the system provides a practical program of networking technology for real-time acquisition and reliable data transmission.It surely increases the real-time and stability of electric parameter acquisition system,which plays an important role on the development of the electric parameter acquisition system.
