Design And Research Of Traffic Alarm Network Communication Scheme Based On ZigBee Wireless Communication Technology

The research on the network communication system of road traffic alarm is put forward against the background of the more developed traffic and the increasing number of accidents in our country.Because of the complexity,uncertainty and multiple factors of traffic accidents in China,the research of wireless traffic alarm system is a heavy and arduous task.Therefore,the current research on traffic alarm is not deep enough.Based on the analysis of the causes of traffic accidents and the existing research results,this paper puts forward the design and research methods of traffic alarm network communication scheme based on ZigBee wireless communication technology.Firstly,this paper analyses the research background and current situation of traffic alarm network at home and abroad.Secondly,it elaborates the characteristics,topological structure and protocol specification of wireless sensor network technology in detail.It also analyses the feasibility of the application of wireless communication technology in traffic alarm network and its advantages in application.In the third chapter,it gives the design of traffic alarm network.The factors needing attention in the process,the specific requirements of wireless network design and the basic content are introduced in detail.Then the ZigBee wireless communication technology is introduced in detail,including the chip selection of ZigBee,the overall design scheme of the wireless traffic alarm network and the design scheme of each subsystem are introduced in detail,and the modules of the system(mainly the data acquisition nodes and paths)are given.Software and hardware implementation method of node and coordinator node.Generally speaking,the design process of the traffic alarm system is based on wireless networking,data acquisition,transmission and analysis,as well as automatic alarm and road co-ordination.The design scheme of this paper gives the corresponding ZigBee network protocol for the complexity of road structure and traffic function,which makes the whole network cost-effective,low power consumption and simple.Operation and maintenance,reliability,safety,accuracy and other functions.It is expected that the above research will have a positive impact on alleviating road problems and traffic accidents,and ensure the orderly conduct of road traffic and pedestrian traffic safety.
