摘要

针对当前大多数机械设备运行环境复杂,人员难以接近等特点,为了能够满足机械振动信号采集的需求,设计了一种基于6LoWPAN的无线传感器网络振动监测系统。系统由6LoWPAN无线传感器节点、6LoWPAN网关节点、IPv6传输网络以及互联网终端用户组成。节点采用模块化设计,其中以自带处理器和无线通信功能的CC2630作为节点的核心,选择高精度三轴加速度计ADXL345采集振动数据。利用基于Contiki操作系统上的IAR开发工具设计6LoWPAN协议栈,实现了节点间的组网,将采集到的三轴加速度振动信号通过6LoWPAN无线传感器网络传输到接入IPv6网络的互联网用户终端上,并通过实验结果验证了该系统设计能够满足机械设备的较高频率振动监测的要求。
        In view of the complex operating environment of most mechanical equipment and the difficulty of personnel access, a wireless sensor network vibration monitoring system based on 6LoWPAN is designed to meet the needs of mechanical vibration signal acquisition. The system consists of a 6LoWPAN wireless sensor node, a 6LoWPAN gateway node, an IPv6 transport network, and an Internet terminal user. The node adopts a modular design, in which the CC2630 with its own processor and wireless communication function is used as the core of the node, and the high-precision threeaxis accelerometer ADXL345 is selected to collect the vibration data. The IAR development tool in the Contiki operating system is used to design the 6 LoWPAN protocol stack, which realizes the networking between nodes, and transmits the collected three-axis acceleration vibration signals to the Internet user terminal accessing the IPv6 network through the6 LoWPAN wireless sensor network. The experimental results show that the system design can meet the requirements of higher frequency vibration monitoring of mechanical equipment.
