起重机超重保护仪设计论文

毕业设计（论文）任务书设计题目起重机超重保护仪设计（硬件）毕业设计（论文）要求及原始数据（资料）起重机超重保护仪是监测起重机在起吊中是否超载，发现超载时及时发出报警信号或停止起重，防止事故发生的一种安全保护装置。本次设计的起重机超重保护仪采用应变式称重传感器，它的输出信号为010MV，输出电阻为350欧姆。本保护仪有一个四位的LED数字显示器，用来显示起重机当前的起吊重量。本保护仪应能设定报警限值和保护限值，因此要有若干个按键。本保护仪应能发出声光报警信号，并能控制起重机的起重回路，因此要有两个继电器输出控制信号。本设计采用与51系列兼容的单片机。硬件采用PROTEL99或DXP软件进行电路设计。本课题分为硬件设计和软件设计两的子题目，由两名同学分别做设计。本设计为硬件部分。指导教师可提供条件和经费和设G3803，进行G17153G1092G1815器件G451G2164G5049电路G7507和G13464装G451G16855G16809和测G16809测G16809G4466G20576G12573。设计条件和设计要G8726G7261G451称重传感器输出G9801G6947G5242G7262MV/V2G451要G8726采用单片机G1881部的A/DG17728G6454，G17728G6454G17907G5242G993G4579G11221000次/G121983G451供电电G2399G726220VG1144G89814G451称重传感器G7737路电阻G7263505G451G1946G11842G5242G726G1260G11222（论文）主要工作内容G29G3G20G451G3G7053G7708设计G3G21G451G3G1815器件G17885G3423G3G22G451G3电路设计G3G23G451G3G2372G2059电路G7507设计G3G24G451G3G13546G1901G1147G2709G16840G7138G1082。G3G25G451G3G13546G1901设计G16840G7138G1082G12573设计G7003件。G125442G20041学生应交出的设计文件（论文）设计说明书，包括1G451设计G16840G7138G7272G451G1363用G16840G7138G10823G451电G2419G10714G3282G7274G451PCBG32825G451G1815件G9177单G7276G451重要G1815件的G2454数G17885G6333计G12651G1082G7277G451光G11436G7003件。8G451G3818G7003G17176G7021G16805G7003一G12699。G125443G20041主要参考文献（资料）1G451G4437G8886G7619G2159传感器制G17908有限G1856G2508G457传感器G16840G7138G1082G458G7272G451G1815器件G6175G1888G7273G451电路G3282G451G2372G2059电路计G12651机G17753G2173设计软件G6175G1888G7274G451G11468G1863教G7460。A1A0A2A3A5A4A62006A31A2A8A7A10A9A11A12A14A13A16A15A17A18A19A202010A223A231A192010A226A2318A19A24A21A25A26A27A29A19A20A25A28A30A31A32A33A34A27A29A19A20A36A31A32A35A37A27A29A19A20G125444G20041I起重机超载限制器设计摘要起重机超载限制器G708CRANEOVERLOADLIMITERG709是一种重要的起重机超载保护装置。它G1039要装G3803在G8785G17722吊，G17730G13986吊和G4665G5114吊G12573G3835G3423起重机G990。G17902G17819系G13491G1881的传感器G4557起重机的G1863键G5049G1328G2454数进行G4466时G7828测，经G17819分G7524计G12651和数G6466G3800G10714G5483G2052G13479G7536并G13479G2524起重机的当前G5049G1929进行G2040G7041G726当G4466G19481载G14667G6521G17829起重机的G19762安全G5049G1328G14551G3272时，系G13491G20056报警。超G17819G19762安全G5049G1328G14551G3272时，系G13491报警并G14270G2172进行安全保护控制，禁止起重机向危险G7053向G2172G1328。本G7003设计了一种单片机嵌入式起重机超载限制器，电源，传感器信号采集端，模拟信号放G3835电路，ADG17728G6454电路，天线部分，光电报警电路，232G6521口电路，按键设计和LCD显示部G12573部分构成。仪器G1039要功能有显示重量，显示G990限G12573。报警包括超限报警和保护报警，报警G7053式设置了光电报警，同时，该限制器具有短距离无线G17902讯的能G2159，G1363之应用更G2164广泛，G1363用更G2164G7053便。目前国G19481化的趋势是保护仪想G4579G3423化，模块化，集成化，智能化发展，其技术性能趋向G17907率高G1946G11842G5242高，稳定性高，可靠性高G12573。G1863键字G726单片机CC2430，单片机嵌入式起重机超载限制器，LCD显示器IIHOISTCRANEOVERLOADPROTECTIONMETERHARDWAREDESIGNABSTRACTCRANEOVERLOADLIMITERCRANEOVERLOADLIMITERISANIMPORTANTCRANEOVERLOADPROTECTIONDEVICEITSMAINEQUIPMENTINTHEVEHICLESUSPENSION,TIRESANDOTHERLARGECRANEANDCRAWLERCRANETHROUGHTHESYSTEMOFSENSORSONTHECRANESKEYOPERATINGPARAMETERSINREALTIMEDETECTION,AFTERANALYZINGTHERESULTSOFCALCULATIONANDDATAPROCESSINGARECOMBINEDWITHACRANETOJUDGETHECURRENTCONDITIONSLOADCLOSETOTHECRANEWHENTHEACTUALSCOPEOFWORKOFNONSECURITY,THESYSTEMPREALARMSCOPEOFWORKMORETHANNONSECURITY,THESYSTEMSECURITYALARMANDAUTOMATICALLYCONTROLTHEDIRECTIONOFTHEDANGEROUSACTIONAGAINSTCRANETHISPAPERPRESENTSASINGLECHIPEMBEDDEDCRANEOVERLOADLIMITER,POWER,SENSORSIGNALACQUISITIONEND,ANALOGSIGNALCONDITIONINGCIRCUIT,ADCONVERTERCIRCUIT,ANTENNA,PHOTOELECTRICALARMCIRCUIT,232INTERFACE,BUTTONSANDLCDDISPLAYUNIT,ETCTODESIGNPARTSINSTRUMENTSHOWINGTHEWEIGHTOFTHEMAINFEATURES,SHOWINGCEILINGINCLUDINGOVERLIMITALARMANDPROTECTIONALARMALARMALARMSETTINGTHEPHOTOELECTRICALARM,SAMETIME,THELIMITERHASASHORTRANGEWIRELESSCOMMUNICATIONSCAPABILITY,SOTHATTHEAPPLICATIONOFMOREEXTENSIVEANDEASIERTOUSETHECURRENTINTERNATIONALTRENDISTOPROTECTTHEINSTRUMENTTOSMALL,MODULAR,INTEGRATED,INTELLIGENTDEVELOPMENT,ITSTECHNICALPERFORMANCETENDTORATEHIGHACCURACY,HIGHSTABILITYANDHIGHRELIABILITYKEYWORDSSCMCC2430,CRANEOVERLOADLIMITEREMBEDDEDMCU,LCDDISPLAY目录A38A39IABSTRACTIIA40A41A42A43A44111A45A46A47A48A49A50A511111A52A53A54A551112A56A57A58A59A57A60A61A62A63A64A65A66212A67A68A69A70A71A72A73A74A75A76A77A784A79A80A81A82A83A84A85A83A86A87A88A89A90A91A92A93A94A83A84A85A83A86A87A88A89A90A91A92521A95A96A97A985211A99A100A101A102A1035212A99A100A104A105A1035223A106A107A108622A109A110A111A112A109A110A111623A113A114A115A1166231A117A118A1196232A120A121A1196233A122A123A1197234A124A125A119724A126A127A128A129A130725A131A132A129A130726A133A134A135A1368261A117A1188262A137A1388263A124A1398264A140A1418264A142A143A144A145A120A1218266A146A147A144A145A120A1218A148A149A150A151A152A153A154A155A156A157A152A153A154A155A156A157931A158A159A1609311A161A1629312A163A1649313A165A166A167A168A169A170A171A1721132A173A174A17512321A161A16212322A176A177A178A179A180A181A172A167A163A16413323A165A166A167A182A183A180A181A184A1851333A186A18714331A161A16214332A165A166A167A188A1891434A190A191A17516341A161A16216342A192A193A172A167A163A16416343A165A166A167A192A193A1721635A194A195A196A197A198A19917351CC2430A200A20118352CC2430A167A202A203A204A205A17220A206A207A208A209A210A211A212A210A213A214A215A216A217A218A219A210A211A212A210A213A214A215A216A217A218A2192041A220A221A222A2232042A224A225A226A227A228A229A230A2312143A232A233A227A228A234A235A
