基于plc的自动门控制系统设计摘要:现在越来越多的公共场所例如广场、宾馆等开始使用自动旋转门，同时现在大家对他的一些安全方面的要求也变得更高。在本文中就研究了将旋转门与自动控制原理结合起来以提高安全门的安全性等问题。首先讨论了当前在国内外旋转门的安全性后通过与PLC技术结合设计了基于PLC的自动门控制系统。这个设计的最重要的部分就是PLC部分，同时还跟许多的红外传感器等结合起来，来确保不管在任何情况下，当有人在出入门的时候，都能够在不碰到人的前提下保证安全性。除此之外，本文中还设计了配合机械知识来进行安全性保障的部分，例如当门受到过大的阻力时会马上停止工作。结合以上多种的设计方案就可以确保在任何情况下都不会出现有人被门夹住等问题，完全保证人的安全。在本文的最后还有一部分关于自我诊断问题的部分，能够保证及时的处理问题，以防止出现更大的问题。关键词：非接触检测，楼宇自动化，故障诊断DesignofautomaticdoorcontrolsystembasedonplcABSTRACT:Withautomaticrevolvingdoorbeing“edtoguesthouses，hotels，buildings，luxuryapartments，large—scaleenterprisesetc．，Peoplehaveincreasedrequirementsaboutitscomfortandsecurity．Therefore，in蛳spaper,bycombiningthetraditionalrevolvingdoorwithautomaticcontrol妒chnology,theautomaticcontrolsystem，whichCallimprovethesafetyoftherevolvingdooLwasresearchedanddesigned.Byanalyzingtheexistingrevolvingdoorcontrolsystemforitslowsecurity,therevolvingdoorcontrolsystembasedonthePLCWasresearchedanddesigned．Thecorecomponentsusedprogrammablelogiccontroller,andthemultipleinfraredsensorswereadded．Anumberofadditionalsecurityfeaturestoensurethatthedoorintherotation,intermsofimport，exportortransferintheinternaldoors，areallwithnon．contactsafetyandsecurity．Inaddition，thedesignofthe”mechanical”securitysystem：Whentheautomaticdoorrotary-wingresistanceisgreaterthanthevalue(adjustablesettings)，theautomaticdoorsatonce-stopspinning．Intheprotectionofmultiplesecuritysystems，weCanguaranteethatnoincidentofpeoplefoldertakeplaceandprotectusersandpedestrians．Finally,afaultself-diagnosissystemWasdesignedSOthatmanagersCansuittheremedyandtaketimelymeasurestopreventtheexpansionoffailure，SOastoavoidTheaccidenttakingplace.KEYWORDS：non—contactdetection，buildingautomation,faultdiagnosis目录................................................................................................................................................3............................................................................................................................3...........................................................................................................................4.........................................................................................................................4.........................................................................................6.................................................................................................6...................................................................................................................7........................................................................................9.......................................................................................................................9.......................................................................................................................9...........................................................................
