Research And Design Of Wireless Temperature Sensor Base On ZigBee Protocol

With the progresses of computer networks and communication technology, newtheories, standards and technology will be endless. Wireless communication from the3G wireless communication network to the wireless network access and to the IEEE802.11x wireless LAN,networks become ubiquitous,and our lives have become closerand closer.Wireless Sensor Network(WSN) is a new-type network which involves sensortechnology,ernbedded computing technology, distributed information technology andwireless communication technology．It is able to monitor,apperceive and collect allkinds of information about environment and monitored things in the networkdistributed field momentarily．During the procession, the information is processed byembedded system and sent to terminal user via random autonomous wirelesscommunication network with multi-hop relay manner．It is the advanced researchhotspot field of recent international attention．The main works finished in this thesis are as follows:(1) Based on CC2530from hardware design aspect,completes the electricalcircuit design of coordinator,router and terminal device,and also analyses the designof the peripheral circuit module of each kind of the sensor points.(2) Completes the program design of intelligent gateway,and displays the detailprogram design,core code,Code comments based on the function of intelligentgateway.(3) Completes the program design of coordinator,router and terminaldevice.analyses the basic function and program flow of the three kind of sensorpoint.Displays the detail program design,core code,code comments based on thefunction of coordinator,router and terminal device.(4) Complete the program design of the Android user control terminal.Analysesthe basic part and work flow of Android user control terminal.Displays the detailprogram design,core code,code comments of some important submodular.In the end, the article has demonstrated the feasibility and reliability of thesystem by a small temperature WSN with several temperature sensors.The system can complete the real-time detection of temperature value and achieve good results.
