Node design of an internet of things node for ocean environment oriented data collection and dynamic monitoring

为了实现海洋环境的有效监控,设计了一种面向海洋环境数据采集和动态监控的物联网节点。首先,定义了系统模型,将系统分为无线传感器网络、Sink节点和监控中心,将系统中的节点分为传感器节点和Sink节点,然后对传感器节点、Sink节点、传感器接口电路以及监控中心的硬件均进行了设计和描述,同时对传感器节点和Sink节点的软件流程进行了设计。系统测试表明文中方法能对海洋环境信息进行实时数据采集和动态监控,当出现异常情况时,给出报警以对用户进行提示,同时死亡节点数较少,具有成本低、功耗低和可靠性高的优点,具有很强的可行性。

In order to monitor ocean environment effectively,an internet of things node for ocean environment oriented data collection and dynamic monitoring is proposed.Firstly,the system model is defined.The system is divided into wireless sensor network,sink node and monitoring center,while the nodes in the system is divided into the sensor node and the Sink node, then the sensor node,the Sink node,the interface circuit and the monitoring center hardware are designed and described.Soft-ware flow for the sensor node and the Sink node is designed.The experiment shows that the method can realize ocean environ-ment oriented data collection in real-time and dynamic monitoring,and when the exceptional case emerges,the alarm is given to the user.It has a small number of dead nodes,and has the characteristics of low cost,low power consumption and higher relia-bility,with strong feasibility.
