无线传感器网络是通过无线通信方式形成的一个多跳自组织网络。传感器节点是无线传感器网络的基本单元,节点设计的好坏直接影响到整个网络的质量。为满足无线传感器网络可靠性和持久性的要求,尽可能地降低传感器节点的功耗成为设计的核心要素。通过对节点功耗的分析研究,选择以MSP430F149作为处理器的传感器,满足了低功耗设计要求,可以实现无线传感器在煤矿监测以及复杂地理环境下的应用。
Wireless sensor network is a multi-hop self-organizing network formed by wireless communication. Sensor node is the basic unit of wireless sensor network. The quality of node design directly affects the quality of the whole network. To meet the reliability and durability requirements of wireless sensor networks, reducing the power consumption of sensor nodes as much as possible becomes the core of the design. Through the analysis of the node power consumption, we choose the MSP430F149 as the sensor of the processor to meet the design requirements of low power consumption, which can realize the application of wireless sensor in coal mine monitoring and complex geography environment.
