摘要
由于单片机数据处理速率低,而AMR7缺乏存储管理单元,基于这些设备的自动抄表系统难以满足电力系统对负荷控制的精细化要求。在此设计了一种基于ARM9和GPRS的实时电力负控管理系统,本设计重点利用ARM9微处理器采集速率高、处理能力强的特点,提高了系统的精确度;利用Linux2.6操作系统较高的实时性提高了系统的响应速度;利用宽带GPRS网络实现了用电信息的无线采集和实时监测等功能。该系统已被电力部门试用,在实际应用中抄表速度快、实时性强,基本达到了电力部门的使用需求,为电力部门提高管理水平和实现电管理现代化提供了技术保障。
Since SCM has low processing rate,ARM7 lacks of MMU,and the automatic meter-reading system based on the devices mentioned above can not satisfy the requirement of power supply system to load control,a real-time load control and management system based on ARM9 and GPRS is proposed in this paper.This system has been tried out by the power department.It can read meter swiftly and has a perfect real-time performance in practical application.This system can meet the demands of the power department basically.It provides technical support for improving management level and electricity consumption management modernization of power department.
