基于ZigBee技术的数据采集系统的设计

摘要

As a short distance communication technology, ZigBee is a ideal data transmission method for wireless sensor networks for its low cost and power consumption. And the data acquisition system based on wireless sensor network is widely used in industry and agriculture. Based on ZigBee protocol, the data acquisition node, terminal node and the monitor software are designed and implemented, at the same time, the data transmission on the wireless sensor network is implemented on the network routing. The trusted security protocol based on LBlock algorithm is designed to achieve the security of data trans-mission. The experiment shows that the data acquisition system can be used to acquisition and monitor va-rious kind of data.%作为一种短距离通信技术,ZigBee以其低成本和低功耗成为无线传感器网络的一种理想数据传输方法。基于无线传感器网络的数据采集系统在工农业中有广泛的用途。基于ZigBee协议,设计并实现了无线传感器网络中的终端节点、数据采集节点和系统的监控软件,同时采用Zig-Bee协议在网络路由的基础上实现了传感器网络的组网和传输。为了保证数据参数的安全性,在无线传感器网络中采用LBlock算法实现受信任的安全协议。实验表明,该数据采集系统能够实时采集和监控多种信息数据。
