【摘要】：为了实现智能家居安防系统的监测需求,并解决以往监控系统中网关存在的丢包率高、可靠性低和能耗高的问题,设计了一种基于改进UDP协议的物联网网关。首先,设计了以S3C2410为微控制器、DM9000为以太网芯片、EC189为3G模块和XBEE ZNET为无线通信模块的网关节点,然后,定义了MAC层的改进的T-MAC通信协议和对应的数据帧格式,在网络层设计了一种基于改进LEACH协议的低功耗分簇路由协议,在数据传输层定义了基于改进UDP的协议以实现数据的可靠传输,并定义了网关的软件流程。实验结果证明设计的网关能实现协议之间的转换,具有数据丢包率低、可靠性高和能耗低的优点,能辅助系统实现室内数据的实时采集和监控,并在数据异常时进行报警提示。
[Abstract]:In order to realize the monitoring requirement of smart home security system, and to solve the problems of high packet loss rate, low reliability and high energy consumption, a kind of Internet of things gateway based on improved UDP protocol is designed.Firstly, the gateway node with S3C2410 as microcontroller and Ethernet chip EC189 as 3G module and XBEE ZNET as wireless communication module is designed. Then, the improved T-MAC communication protocol and corresponding data frame format of MAC layer are defined.A low power clustering routing protocol based on improved LEACH protocol is designed in the network layer. In the data transmission layer, the protocol based on improved UDP is defined to achieve reliable data transmission, and the software flow of the gateway is defined.The experimental results show that the gateway can realize the conversion between protocols, which has the advantages of low packet loss rate, high reliability and low energy consumption. It can assist the system to realize the real-time collection and monitoring of indoor data, and alarm and prompt if the data is abnormal.
