无线传感器网络是一项基于无线网络通信、在普适环境下可实现区域性信息采集的网络技术。基于Nios II系列32位RISC嵌入式处理器Nios II,采用创新的三维IP地址分配法,结合传统无线网络技术和MAC协议,设计了一个通用性较强的无线传感器网络模型。同时利用太阳能和节点自身携带微型电池协同供电,太阳能充电的双模式供电法,在无线传感网络的能源问题上作出了改进。
Wireless sensor network is a network technology based on wireless network communication that can realize regional information collection under universal environment. Based on the Nios II II, a Nios II series 32-bit RISC embedded processor, an innovative three-dimensional IP address allocation method is adopted to combine the traditional wireless network technology with the MAC protocol to design a universal wireless sensor network model. At the same time, the solar cell and the node itself are used to carry the micro-battery to supply power in coordination with each other. The dual-mode solar power charging method is improved on the energy problem of the wireless sensor network.
