摘要:

WIA-PA是一种新兴的工业无线传感器网络协议,提出一种基于WIA-PA协议的农田温湿度信息传感网络的设计与实现方法;主要从事基于分层状态机原理构建WIA-PA的各层协议,并采用QP(Quantum Platform)量子编程平台作为任务调度的枢纽;主要从事温湿度传感器节点通过星状网和网状网组合形式组建成自组织的无线网络,并将信息汇聚至网关节点;主要从事此外,设计了传感器协议的低功耗模式和网关与服务器之间信息交互的协议,并对设计的WIA-PA传感网络的功耗以及丢包率等进行了实测,验证了所设计传感网的良好性能。

Abstract:

WIA-PA is an emerging industrial wireless sensor network protocol. This paper proposes a kind of design and implementation method for the farmland temperature and humidity sensor network based on WIA-PA protocol. The layers of the protocol are built on the basis of the principle of hierarchical state machine. And WIA-PA uses the QP (Quantum Platform) programming platform as a hub of task scheduling. Star network and mesh network are combined to form the self-organized wireless network by the temperature and humidity sensor nodes, and the sensor information will be gathered to the gateway node. In addition, the system is designed to be with low power consumption. And the interaction between the gateway and the server has also been achieved by an agreement. What’s more, the power consumption of the sensor network and the packet loss rate are measured, and the design is proved to be effective and reliable.
