无线传感器网络具有布线灵活、低功耗的特点，能在恶劣环境下可靠工作，适合温度采集。本文介绍了基于ISO18000-7标准的DASH7无线技术，探讨了无线SoC芯片CC430的结构特点和工作原理，设计一种星形拓扑结构的温度无线传感器网络，提出一种节能能量模型和通信协议，并对协议进行了能量优化。%Because of routing flexibility, low power consumption, and working reliably in harsh environments, wireless sensor network is ideal for temperature acquisition. This paper introduces DASH7 technology evolved from ISO18000-7 and wireless SoC chip CC430, proposes a temperature wireless sensor network with star topology. Based on the hardware, a wireless communication protocol proposed and energy consumption from the aspect of protocol through simulation optimized.
