碩士 === 華梵大學 === 電子工程學系碩士班 === 98 === ZigBee is a short-range wireless standard based on IEEE 802.15.4 and ZigBee protocol stack theorem which developed by ZigBee Alliance. The specification of ZigBee supports low-power, low cost, short distance and data transmission rate of 20k up to 250k bps. In this thesis, we utilize ZigBee modules provide by chip set venders and tool kid OEM to fast construct ZigBee network. The studies and investigations on ZigBee properties and ZigBee protocol are then followed. At the beginning, we take ZigBee modules that adopt ZigBee solutions of Jennic SOC chip, JN5121, to accomplish the environment monitoring. When a ZigBee network is easily configured under AT-Command interface, environmental data are sampled by sensor modules and are transmitted to a PC server via the ZigBee network. Data are stored in a databank and its time varying curve is shown on a webpage. In protocol studies, ZigBee modules work in CC2530 ZigBee chip solutions of Texas Instruments are considered. Our attention reach to Z-Stack protocol stack architecture, GenericApp example, ZigBee programming; device startup, associating, Binding, Routing and data displaying. At the end, experiment on temperature acquisition brings discussions on network topology and data routing. In the experiment, ZigBee network properties along with its typical topologies are examined.
