为了实现低成本连续在线监测,提出了ZigBee网络测控系统;将嵌入式操作系统linux进行移植构建ARMlinux嵌入式开发平台,利用该平台设计了一种ZigBee无线传感器网络监控系统;该系统把JN5121作为无线网络设备微控制器,内嵌ARM9核的S3C2410与JN5121共同构成网络数据采集集中器;硬件电路复用率高,实现了无线网络与远程监控中心的通信连接;实验结果表明该系统功耗低、工作时问长、能自组织地通信以及在危险区域和大面积监测中容易布置,较传统在线监测系统具有更大的优势。
In order to achieve low--cost, continuous on--line monitoring designed the ZigBee network test and control system. The key points of transplanting embedded OS linux were introduced, and the embedded ARM--linux development platform was designed. A ZigBee wireless sensor network monitoring system based on the platform was achieved. JN5121 as a single--chip microprocessor was designed to be wireless microcontroller, while S3C2410 with an advanced ARM9 core and JNS121 were made to be net data concentrator. The design has high rate hardware reusing device that can well communicate with remote control center.
