摘要: 针对传统振动检测系统中组网能力弱、通信速率低等问题,设计了一种基于ZigBee和以太网传输的振动检测系统。系统具有三层结构,测量节点N与路由节点R之间采用基于XBee-PRO的ZigBee方案构建通信网络,以适应多测点和大空间分布的应用场合;路由节点R与用户终端层采用基于LwIP的以太网方案完成通信,以保证数据实时、可靠地传输;用户终端层的服务器节点S将数据暂存在SD卡中,供PC端读取分析。实验结果表明,这种三层结构的测量方案能充分发挥ZigBee的分布式组网优势和以太网的高速稳定优势,既实现对振动检测系统中测量点的有效控制,又满足测点广泛分布和数据实时传输的需求。

Abstract: In the traditional method of vibration measurement system, the ability of the network construction is weak and the transmission rate is slow. In order to solve these problems, a new kind of vibration measurement was designed using ZigBee and Ethernet. There are three layers in the system. ZigBee based on XBee-PRO was used to establish the communication between collector nodes and router nodes to suit the multipoint and long-span measurement. Ethernet based on LwIP was used to make the data transmitted accurately in real-time. On the end device layer, the data were stored in SD-card in a server node and offered to computers. The experimental results show that the three layers structure of the measurement system combines the strength of ZigBee's network construction ability and Ethernet's high speed and good stability. It can not only realize an effective control to the measure points, but also meet the requirements of a long-span measurement and a real-time data transmission.
