基于ZigBee技术的室内环境检测系统设计摘要随着嵌入式计算、传感器、无线通信等技术的飞速发展，无线传感网被广泛应用于环境监测、军事国防和工农业控制等诸多领域，已成为电子信息技术发展的一个热点。CC2530是TI公司针对ZigBee的无线传感网芯片解决方案，具有功耗低，可靠性高，组网简单等优势。基于CC2530和ZigBee协议，设计了温湿度数据采集系统，分别给出了协调器和普通节点的软件算法，在干扰环境下测试表明，网络具有较强的鲁棒性和自组能力。本文主要介绍基于STC12C5608AD单片机为核心的家庭环境监测系统的硬件电路设计和软件流程设计，实现了在家庭环境中对温度、湿度、灯光及家用电能质量的检测，其中分别用相应传感器、电流互感器、电压互感器。其中，将温度、湿度、灯光传感器的模拟量经过单片机AD转换处理后输出相应的控制动作调节相应参数；电能质量的检测，将互感器与电能质量及单相双向功率集成电路芯片CS5460A结合检测电压、电流、功率等检测，经单片机输出相应保护控制:瞬时过电流保护，过载保护、过电压保护、失压保护等。本设计使用ZigBee无线网络协议，将系统参数传输及控制，也可与上位机实时通讯和监控。关键词：单片机，传感器，ZigBee，环境监测，继电保护DesignofIndoorEnvironmentMonitoringSystemBasedonZigBeeTechnologyABSTRACTWiththerapiddevelopmentofembeddedcomputing,sensor,wirelesscommunicationtechnology,wirelesssensornetworkiswidelyusedinenvironmentalmonitoring,militarydefense,industrialandagriculturalcontrolfields,hasbecomeahotspotinthedevelopmentofelectronicinformationtechnology.CC2530isawirelesssensornetworkchipforZigBeeTIsolution,withlowpowerconsumption,highreliability,simplenetworkingadvantages.CC2530andbasedonZigBeeprotocol,designthetemperatureandhumiditydataacquisitionsystem,thesoftwarealgorithmcoordinatorandordinarynodesaregivenrespectively,testedininterferenceenvironment,thenetworkhasstrongrobustnessandself-organizingability.ThispapermainlyintroducesthedesignofhardwarecircuitandsoftwareflowdesignoffamilyenvironmentmonitoringsystembasedonSTC12C5608ADSCMasthecore,realizesinthehomeenvironmentoftemperature,humidity,lightingandhouseholdelectricalenergyqualitydetection,whichweretreatedwithcorrespondingsensors,currenttransformer,voltagetransformer.Amongthem,theanalogtemperature,humidity,lightsensorthroughtheSCMADconversionprocessingoutputcontrolactioncorrespondingadjustingthecorrespondingparameters;detectionofpowerquality,thetransformerandpowerqualityandsinglephasebidirectionalpowerintegratedcircuitchipCS5460Acombineddetectionofvoltage,current,powerdetection,SCMoutputscorrespondingprotectioncontrol:instantaneousovercurrentprotection,overloadprotection,over-voltageprotection,under-voltageprotectionetc..ThisdesignusesZigBeewirelessnetworkprotocol,thesystemparametersoftransmissionandcontrol,isalsoavailablewithaPCreal-timecommunicationandmonitoring.Keywords:Microcontroller,Sensor,ZigBee,EnvironmentalMonitoring,目录第1章绪论............................................................11.1本文研究背景与意义..............................................................................................11.2智能家居环境监测系统的特点..............................................................................11.3国内外发展现状及分析..........................................................................................21.4典型无线网络技术介绍..........................................................................................31.4.1ZigBee技术.................................................................................................
