齐齐哈尔大学毕业设计（论文）题目基于无线传感器网络的精准农业环境监测系统设计学院通信与电子工程学院专业班级物联网111班学生姓名卢旭指导教师苗凤娟成绩2015年6月25日摘要众所周知，无线传感器技术已经成为农业环境监测的主要技术，通过该技术解决了传统农业环境监测的诸多问题，比如：设备繁多、维修困难；布线繁琐、容易腐化；规模庞大、不易管理等。本设计基于无线传感器网络技术根据要求不仅能够采集农业环境参数，还利用视频技术采集了环境的图像信息，这样不仅从数据分析上得到农业环境参数，更能通过图像直观的观测农田环境，为本设计提供更可靠的依据。本设计融合软件和硬件，对于无线传输硬件，选择了Zigbee模块和Wifi模块，Zigbee模块主要负责传输传感器的数据，Wifi负责传输视频，因为需要采集温湿度、二氧化碳浓度和光照强度，所以比较了多种传感器后，温湿度传感器选择DHT11，二氧化碳传感器使用MG811，对于光照强度传感器使用BH1750。传感器监测节点很简单，传感器采集数据经过Zigbee模块传送给协调器，由协调器在传送到上位机即可。另一部分采用Wifi模块传输摄像头采集的视频，将视频传输到上位机，监测农作物是否有病虫害，或者是否有人侵入等。软件则涉及了Altiumdesigner设计硬件的电路图，上位机选用VisualStudio2013，程序设计语言C#，PC机接将数据存储、分析，若是超出了设置的范围，则会自动实现报警功能，真正实现远程监测的功能。关键词：环境监测系统；无线传感器网络；传感器；协调器；AbstractAsweallknow,thewirelesssensortechnologyhasbecomeamajoragriculturaltechnologyforenvironmentalmonitoring,throughthetechnologytosolvethemanyproblemsoftraditionalagricultureenvironmentalmonitoring,suchas:equipmentrange,difficultmaintenance;wiringcumbersome,easytocorrupt;large-scale,difficulttomanageandsoon.Thedesignisbasedonwirelesssensornetworktechnologycannotonlycollectaccordingtotherequirementsofagriculturalenvironmentalparameters,butalsotheuseofvideotechnologytocollecttheimageinformationenvironment,sothatnotonlytheagriculturalenvironmentparametersobtainedfromthedataanalysis,moreintuitiveobservationbyimagefarmlandenvironment-orienteddesignedtoprovideamorereliablebasis.Theintegrationofsoftwareandhardwaredesign,hardwareforwirelesstransmission,selecttheZigbeemoduleandWifimodule,Zigbeemoduleismainlyresponsibleforthedatatransmissionofthesensor,Wifiresponsibleforthetransmissionofvideo,becauseyouneedtocollecttemperature,humidity,carbondioxideconcentrationandlightintensity,itismoreamoreafterthekindofsensor,temperatureandhumiditysensorselectionDHT11,carbondioxidesensorsMG811,thelightintensitysensorsBH1750.SensorsmonitornodeissimplesensortocollectdatatothecoordinatorafterZigbeemodule,bythecoordinatorinthetransmissiontothehostcomputercanbe.AnotherpartofWifimoduletransmissioncameratocapturethevideo,thevideotransmissiontothehostcomputer,monitorcropsiftherearepestsanddiseases,orwhethersomeonebreaksthelike.Altiumdesignersoftwareinvolvesthedesignofhardwarecircuit,thehostmachineselectsVisualStudio2013,theprogramminglanguageC#,PCmachinesconnectedtodatastorage,analysis,ifbeyondthescopesetalarmfunctionwillautomaticallytrulyremotemonitoringfunctions.Keywords:environmentalmonitoringsystem;wirelesssensornetworks;coordinator;sensors;目录摘要.........................................................................................................................................IAbstract......................................................................................................................................II第1章绪论..............................................................
