摘　　要：无线传感器网络(Wireless Sensor Network, WSN)节点规模大、部署场合多样,现场更新较为困难。为实现无线传感器的远程灵活配置,同时满足其低成本、低功耗要求,提出一种基于现场可编程门阵列(Field Programmable Gate Arrays, FPGA)的远程可重构无线传感器设计方法。该方法在ZigBee网络基础上自定义远程访问协议和无线上传算法,并通过XBee模块进行远程通信;无需外部控制芯片或内部软核处理器,直接将接收到的配置信息通过FPGA传感器内部顶层状态机和ICAPE2原语写入FLASH配置空间,经多重校验后启动重构命令完成无线传感器节点的远程更新。实验针对6个传感器节点进行远程更新验证,结果表明,该方法相比于同类FPGA远程重构方法具有更低的功耗和更少的资源消耗,适用于大规模WSN节点的远程更新配置。Wireless Sensor Network(WSN)has a large scale of nodes and diverse deployment scenarios,and on-site updates are difficult.In order to realize the remote and flexible configuration of wireless sensors,while meeting their low-cost and low-power requirements,an FPGA-based remote reconfigurable wireless sensor design method is proposed.This method customizes the remote access protocol and wireless upload algorithm on the basis of the ZigBee network,and performs remote communication through the XBee module;no external control chip or internal soft-core processor is required,and the received configuration information is directly written into the FLASH configuration space through the top-level state machine and ICAPE2 primitives inside the FPGA sensor.After multiple verifications,start the reconstruction command to complete the remote update of the wireless sensor node.The experiment performed remote update verification on six sensor nodes.The results show that this method has lower power consumption and less resource consumption than that of similar FPGA remote reconstruction methods,and is suitable for remote update configuration of large-scale WSN nodes.
