摘要
介绍了一种基于ARM和GPBS技术的无线自动抄表系统的设计方案,该系统将Atmel AT91SAM9260工业级处理器和ARM Cortex M3处理器分别作为集中器和采集器的核心处理器,以嵌入式μC/OS-II实时系统作为软件开发平台,上行通道采用GPRS无线通信方式,下行通道采用RS-485串口和电力载波传输数据,该系统具有成本低、传输速度快、可靠性高、实时性好的优点,较好地满足了远程自动抄表的要求,具有较高的实用价值。
A wireless automatic meter reading system based on ARM and GPRS technology is designed. This system uses Atmel Ar[91SAM9260 and ARM Cortex M3 as the main processors of the concentrator and collec- tor, and uses μC/OS-Ⅱ as the software development platform. Upstream uses GPRS wireless communication, downlink channel uses RS485 and power line carrier to transfer data. This system has many benefits such as low-cost, fast transmission speed, high reliability and real-time, meets the requirement in automatic meter read- ing system well. It has a high practical application value.
