Title  The design of environmental data collection terminal based on ZigBee                   

Abstract

In recent years, as the development of the wireless networks and sensor technology, the social informatization, family intelligent and industrial automation etc for wireless data transmission and increasing demand, the ZigBee agreement as a new standard of wireless sensor network technology came into being, and showed the rapid development of the good momentum, widely applied to the wireless connection.

In this paper, a kind of wireless data acquisition system which is based on ZigBee technique is put forward . It introduces ZigBee wireless communication standard, the constitution and communication method of network, and analyzes all the primitive services of PHY-Layer(Physical) and MAC-Layer(Media Access Control layer),and generalizes the types and structures of the frames that are transferred between the two layers. Second, functions of wireless sensor nodes to be designed and analyzed from the aspects of low power consumption and low cost. Finally, the hardware circuits design and platform construction which based on the chip CC2530 are completed. At last, the experiments and test of the system are given out. The result of testing shows that the system works stablely, the whole system meets the designing requirements in terms of function and effectiveness.

Keywords: acquisition system; the ZigBee agreement; wireless sensor network; CC2530
