摘要
针对目前水族馆中的水温监控系统存在的实时性差和有线网络布线复杂的问题,设计了一种将Zig Bee无线传感器网络(WSNs)与虚拟仪器相结合的水温控制系统。该系统以ATmega128L单片机和CC2420芯片为核心设计传感器节点,结合MAX232芯片设计Sink节点,实现数据的无线传输和水温的实时监控。该方法克服了传统单一网络的局限性,避免了其它无线通信技术高功耗的缺点。给出了系统的硬件设计和软件流程,并将本系统用于对实际系统的检测与控制,结果表明:该系统具有结构简单、操作方便、实时性较好的优点。
In view of problem of poor real-time and complicated cable network wiring of water temperature monitor system existed in current aquaria,an improved monitoring system combined WSNs of Zig Bee with virtual instruments is designed.The Sink node of the system is mainly designed by ATmega128L SCM and CC2420,combined with MAX232 chip.This system realizes wireless data transmission and real-time monitoring of water temperature and overcome the limitation of single networks and avoids high energy-cost of other wireless communication technology.The design of hardware and the flowchart of software are given.The experiment shows that the system has advantage of simple,convenient and has good real-time.
