摘　　要：为了将无线传感器网络应用于机械振动监测中,提出了一种面向机械振动监测的多数据汇集点的无线网络拓扑结构,以降低数据汇集点的传输负载,增加网络的数据传输速率,平衡网内能量耗散。利用通用无线传感器网络硬件平台,设计实现了网络传输协议和相关辅助机制,构建了无线振动监测试验平台,通过实测试验评估了多数据汇集点网络结构的传输性能。结果表明,利用多数据汇集点的无线传感器网络拓扑结构可以满足1 kH z采样得到的振动数据连续传输要求。In order to employ the wireless sensor networks(WSN) in the mechanical vibration monitoring,a multi-sink-based topological structure of WSN was proposed,which can reduce the transport load of data sink,achieve higher data transport rate and lower energy consumption.With the help of the Micaz motes,the WSN transport protocols and assistant mechanism were designed and implemented.An experiment device for WSN in the mechanical vibration monitoring was built.Experimental result shows that the WSN with multi-sink topology has a better performance for the mechanical vibration monitoring,and with the multi-sink networks,1 kHz sampling frequency can be achieved,which can satisfy the mechanical vibration monitoring.
