远程电网电流数据采集系统的设计

摘要

介绍一个由数据采集终端和数据处理主机组成的远程电网电流数据采集系统设计，采集终端对电网电流进行实时数据采集，通过GPRS/互联网发送至云端的数据处理主机，数据处理主机对数据接收及处理。数据采集终端由STM32完成对A/D采集和GPRS数据发送的控制。%The design of a power⁃grid′s remote current data acquisition system consisting of data acquisition terminal and data processing host is introduced in this paper. The data acquisition terminal executes real⁃time data acquisition of power⁃grid current and transmits the data to the data processing host through GPRS/ Internet. The data processing host receives and processes the data. The chip STM32 is used in the data acquisition terminal to control A/D acquisition and GPRS transmission.
