本文依据变电站用电管理自动化的需求,提出一种变电站电能量远方采集终端的设计方案。该数据采集终端硬件系统的设计基于ARM9处理器,可按照主站设定的采集周期进行电能数据采集,并进行本地处理保存,通过上行通道与主站进行数据交互,可以满足现场的应用。
In this paper, based on the needs of substation power management automation, this paper presents a design scheme of substation remote energy collection terminal. The design of the data acquisition terminal hardware system is based on the ARM9 processor, which can collect the energy data according to the collection cycle set by the master station and perform local processing and saving. The data exchange with the master station through the uplink channel can meet the field application.
