基于ARM9和CC2530的远程无线抄表系统设计

针对有线抄表方式空间局限性大、抗干扰能力差等问题,提出了一种基于ARM和ZigBee协议的远程无线抄表系统。该系统由数据采集、数据传输和集抄中心3部分组成。以低功耗片上系统CC2530为核心,采集器配以相应电能计量芯片STPM01进行数据采集,集中器设置了基于μCLinux操作系统的ARM9嵌入式网关,配备打印机接口、触摸屏接口等,用以实现快速现场查询、处理、存储、测试、打印等功能,并为将来复杂无线传感器数据的接入作准备。该无线电能抄表系统具有实用性强、可靠性高、低功耗和可扩展等特点,配置功率放大电路后,有障碍传输距离400 m左右。

The design of remote wireless meter reading system based on ARM 9 and CC2530

For wired meter reading system has space limitations and poor anti-interference ability,a remote meter reading system based on ARM and ZigBee protocol is proposed.This system consists of three parts：data acquisition,data transmission and control center.Take the low power system-on-chip CC2530 as the core,the design goes together with the corresponding energy metering IC STPM01 for data collection.Concentrator is set up the embedded gateway based on ARM9 and μCLinux operating system.Equipped with printer interface,touch screen interface,etc.,the system is able to achieve rapid on-site inquiry,process,storage,testing,printing and other functions,and make the future preparation of the data access of ubiquitous wireless sensor.The wireless meter reading system has strong practicability,high reliability,low power consumption and extensibility etc,after configuring the power amplification circuit,the transmission distance of about 400 m.
