The Study Of ZigBee Wireless Sensor Networks Applied In Comprehensive Warehouse Monitoring Base-Station

Wireless sensor networks (WSNs) are believed to be the first of the top ten technologies that will change the world in the future. It can be used to collect full and accurate information in any time and any environment. ZigBee is a short-range, low complexity, low-power, low data-rate, low-cost two-way wireless communication technology or wireless networks technology which can be embedded into various devices. Although the comprehensive warehouse monitoring base-station has broken the tranditional monitoring manner and achieved the level of hierarchical, cyberizing and distributed management, it still remains some disadvantages such as the inconvenience of wire routing, diversified data formats and so on. Therefore, the study of how to embed ZigBee technology into the base-station for the purpose of solving the existing problems in the base-station has important significance.According to the analyses of the architecture and features of WSNs, the architecture, features and protocol specifications of ZigBee, appling ZigBee technology into the monitoring base-station is technically feasible. The main reserch of this paper consists of three parts: hardware design, network construction design and software design. The part of hardware design mainly elaborates in detail the base-station improvement design and the circuit design of universal data acquisition node, and elabrates the key issues of circuit design; the part of network construction design makes an anaylsis on several kinds of network topology, thus presenting the best monitoring base-station nodes topology, at the same time this part also introduces the network construction process in the form of the primitives and illustrates the routing mechanism and base-station network address allocation mechanism; the software design part elaborates in detail the software design of the universal data acquisition node and changed part design of the base-station software. Finally, the work done and innovation in this paper has been presented, and the future work has been brought forward.
