Flood Prevention and Early Warning System-NetworkTransmission DesignAbstractThe early warning system is to provide real-time water information for waterconservancy projects such as rivers and related areas for water conservancy managersto make decisions.With the development of wireless sensor networks,zigbee-basedwireless sensor networks have gradually become one of the research hotspots.The research topic of this paper is the network transmission design of the floodcontrol early warning system.First of all,through literature review,we understand the overall researchbackground and significance of the early warning system,and analyze the basictheory and working principle of the network transmission design of the early warningsystem,and summarize it.Secondly,according to the definition of wireless wide area network (WSN),based on Zigbee wireless communication technology,after mastering the Zigbeetransmission protocol,the network structure of the coordination node was designed,the system architecture of the monitoring coordination node was designed accordingto the network structure,and then the hardware part was designed..Finally,the network transmission part of the flood control early warning systemincluding the hardware and software layer of the joint debugging experiment,drawconclusions and analysis.The successful test of the system shows the advantages of stability and speed ofthe transmission part,which can timely collect water level data and timely processdata to be transmitted to the server,and plays an irreplaceable role in the earlywarning system for flood control and wut.Keywords:Flood prevention and early warning;The Internet of things;Networktransmission
