基于ZigBee的土壤含水率检测系统设计.doc

题目：基于ZigBee的土壤含水率检测系统设计中文摘要PAGE\*MERGEFORMAT3【摘要】在农业、生态环境科学等领域的研究中，常常需要测量土壤的湿度。土壤湿度测量具有被测土地面积大、测量点多、需要观测时间长等特点。传统的测试方法是将传感器插入土层，然后进行读数记录，不仅花费大量的时间和人力，而且由于人为等因素还会造成数据测试不准等问题。本文采用CC2530作为核心控制器件，利用埋入地下的土壤湿度传感器检测土壤的湿度，采用基于ZigBee和WSN的自组网通信技术实现远程数据采集，克服了传统土壤湿度检测的缺点，讨论了系统的硬件电路设计、软件编程和系统调试。该系统综合了Zigbee无线网络自组网、自行愈合和超低功耗的优点，能实时监测土壤信息，为进一步简化农业和生态环境的研究操作。最终经过测试结果表明，该系统运行稳定，丢包率低，能及时准确的监控土壤信息，并将土壤含水率维持在适合植物生长的最佳含水量的范围之内。【关键词】CC2530ZigBeeWSN技术低功耗自组网英文摘要【Abstract】Researchinthefieldofagriculture,ecologyandenvironmentalscience,andoftenneedtomeasuresoilmoisture.Soilmoisturemeasurementhasaofmeasuredlandareameasurementpoints,needalongobservationtime.Traditionaltestingmethodsisthesensorintothesoil,andthenreadingtherecord,notonlyspendalotoftimeandeffort,butalsoduetoman-madeandotherfactorscanalsocausedatatestallowedandsoon.Inthispaper,CC2530asthecorecontroldeviceburiedinthegroundsoilmoisturesensordetectsthemoisturecontentofthesoil,theuseofremotedataacquisitionbasedonZigBeeWSNgroupnetworkcommunicationtechnology,toovercomethetraditionalsoilmoisturedetectiondisadvantageofthesystemisdiscussedinthehardwarecircuitdesign,softwareprogrammingandsystemdebugging.ThesystemcombinestheZigBeewirelessnetworkfromthenetworkself-healingandultra-lowpowerconsumptionadvantages,real-timemonitoringofsoilinformationtofurthersimplifytheresearchoperationofagriculturalandecologicalenvironment.Afterthefinaltestresultsshowthatthesystemisstable,lowpacketlossrate,timelyandaccuratemonitoringsoil,andthesoilmoisturecontentismaintainedwithinthescopeoftheoptimummoisturecontentsuitableforplantgrowth.【Keyword】CC2530ZigBeeWSNLowpowerconsumptionAutoAddNetwork目录目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc355820655"一、绪论1HYPERLINK\l"_Toc355820656"1.1课题背景PAGEREF_Toc355820656\h2HYPERLINK\l"_Toc355820657"1.2研究的目的和意义PAGEREF_Toc355820657\h2HYPERLINK\l"_Toc355820658"1.3国内外的发展现状PAGEREF_Toc355820658\h2HYPERLINK\l"_Toc355820659"二、ZigBee简介PAGEREF_Toc355820659\h2HYPERLINK\l"_Toc355820660"2.1Zigbee的概念及特点PAGEREF_
