摘要
简单分析了现有自动抄表技术存在的问题,介绍了ZigBee技术的特点和优势,将ZigBee技术应用于自动抄表系统,提出了无线网络抄表系统方案。该方案利用TI公司的低功耗单片机MSP430F147作为核心处理器,使用Chipcon公司的射频芯片CC2420实现了数据无线收发通信。论述了系统的构成和工作原理,阐明了系统的硬件电路和软件设计。实践表明,把低成本、低功耗的无线Zig-Bee技术应用于自动抄表系统,提高了系统应用的灵活性,同时也减少了抄表系统现场布线带来的各种问题。
The existing problems in automatic meter reading technology are analyzed. The features and superiority of ZigBee technology are introduced briefly ; and the strategy of wireless network meter reading system is proposed by using ZigBee into automatic meter reading system. In the system, the low power consumption single chip computer MSP430F147 from TI is selected as the core processor; and the radio frequency chip CC2420 from Chipcon is used for wireless data communication. The composition and operational principle of the system are expounded; and the hardware circuits and software designed are illustrated. The practice indicates that the low cost and low power consumption wireless ZigBee makes the automatic meter reading system more flexible and eliminates various problems of field cabling problem of the meter reading system.
