摘　　要：针对无线传感器网络自身的可靠性和维护问题,提出了一种基于FPAA(field programmable analog arrays)的自修复智能无线传感器节点的实现方法。该方法以FPAA为核心构成传感器的主要信号调理电路,节点设计有硬件故障自诊断功能,在节点部分硬件模块发生故障的情况下,可修复相应故障,确保节点在无人职守及野外应用时的可靠性,避免节点的直接丢弃。重点介绍了自修复节点的实现方法、软硬件研发并对节点进行了自修复实验研究,分析了自修复节点的功耗及可工作时间,节点能够在2节具有1 700 mAh的AA电池的供电下工作半年时间。This paper focuses on the reliability and maintenance problems of wireless sensor network, and presents a field programmable analog arrays（FPAA） based wireless sensor networks （WSNs） node self-repairing method. This method takes FPAA as the core to construct the signal conditioning circuit of the sensor in a wireless sensor networks node. Hardware fault diagnosis function is implemented in the design of this kind of nodes, with which the node can self-diagnose its hardware faults and repair itself with the self-organization ability of the FPAA chip. This method can ensure the node reliability in unattended service and outdoor applications. This paper introduces the realization meth- od of the self-repairing node, and the software and hardware implementation. The experimental evaluation of the self- repairing function was carried out. The power consumption and service life of the developed serf-repairing node are analyzed which shows that the node can be used for 6 months with two 1 700 mAh AA batteries.
