为研究适应配电网发展需求的监测网络,提出采用集成了ZigBee射频(RF)前端、内存和微控制器的单芯片CC2430进行无线传感器网络节点的硬件设计,并基于μC/OSⅡ嵌入式操作系统和CC2430芯片内置的ZigBee协议栈进行软件设计,实现数据采集处理和无线通信等功能。无线传感器网络节点包括传感器节点和汇聚节点,通过同一款芯片CC2430来实现,在具体的设计过程中,针对不同的功能,传感器节点和汇聚节点在硬件和软件设计上有不同的侧重。本设计具有成本低、性能好和可靠性高的优点,可适应配电网无线监测的要求。
In order to study the monitoring network which adapts to the development demand of distribution network, a single chip CC2430 integrated with ZigBee radio frequency (RF) front end, memory and micro-controller is proposed to design the hardware of WSN node. Based on μC / OSⅡ embedded operating system And CC2430 chip built ZigBee protocol stack software design, data acquisition and processing and wireless communications and other functions. WSN nodes include sensor nodes and sink nodes, which are realized by the same chip CC2430. In the specific design process, sensor nodes and sink nodes have different hardware and software design focuses on different functions. The design has the advantages of low cost, good performance and high reliability, and can meet the requirements of the wireless monitoring of the distribution network.
