基于LoRa技术的物联网终端通信与状态管理系统
资料介绍
提出了一种基于LoRa技术的物联网终端通信与状态管理系统。该系统采用异构网络结构,通过对层与层之间的通信协议与机制进行设计,实现了系统中任意节点间的安全、可靠的双向通信以及系统层面的终端状态管理,并提高了网关设备的计算资源利用率。首先分析了传统的嵌入式终端入网方法,总结归纳了其存在的缺点,并介绍了系统的总体架构。在对网关层、服务器层与应用层间的通信进行概述后,对终端层与网关层间的通信机制与协议进行了详述。最后验证了系统的功能与特性。
In the paper,a LoRa based communication and status managing system of IoT clients is proposed.Heterogeneous network structure is adopted in the system.The communication protocol between layers has been specially designed.The system has fully implemented high security and availability communication between inner nodes and systematic status managing of clients,while the computing resources utilization rate of the gateway devices is also raised.In this paper,the legacy network access system of embedded clients is analyzed firstly,based on which the disadvantages are summarized,and the structure of the system is introduced.After the communications between gateway layer,server layer and application layer are sketched,the communication protocol and procedure between client layer and gateway layer are introduced.Finally,the tests have been done to prove the functions and features of the system.
