PLC programmable controller

Programmable Logic Controller (PLC) idhijitari inoshanda yemagetsi sisitimu yakagadzirirwa chaizvo maapplication munzvimbo dzemaindasitiri.Inoshandisa ndangariro inorongeka kuchengeta mirairo yekuita logic mashandiro, sequential control, nguva, kuverenga, uye arithmetic mashandiro mukati mayo.Iyo inodzora mhando dzakasiyana dzemichina michina kana maitiro ekugadzira kuburikidza nedhijitari kana analog yekupinza uye kubuda.

Programmable Logic Controller (PLC) idhijitari arithmetic controller ine microprocessor ye otomatiki kudzora, iyo inogona kuchengeta nekuita mirairo yekudzora mundangariro dzevanhu chero nguva.Iyo programmable controller inoumbwa neanoshanda mayuniti akadai seCPU, instruction uye data memory, input/output interface, power supply, digital to analog conversion, etc. Mumazuva ekutanga, programmable logic controllers vaingova nebasa re logic control, saka ivo vakanzi programmable logic controllers.Gare gare, nekuvandudzwa kunoramba kuripo, aya mamodule emakombuta ane mabasa akareruka pakutanga aive nemabasa akasiyana siyana, anosanganisira logic control, timing control, analogi control, uye multi machine communication.Iro zita rakachinjwawo kuita Programmable Controller, Zvisineyi, nekuda kwekunetsana kuri pakati pechipfupiso chePC uye chidimbu chePersonal Computer, uye nekuda kwezvikonzero zvechivanhu, vanhu vachiri kushandisa izwi rekuti programmable logic controller, uye vachiri kushandisa chidimbu PLC.Izvo zvakakosha zvePLC programmable logic controller komputa yakatsaurirwa kutonga kwemaindasitiri.Zvikamu zvaro zvakakosha zvinosanganisira: magetsi emagetsi module, CPU module, ndangariro, I / O yekupinda uye yekubuda module, backplane uye rack module, yekutaurirana module, inoshanda module, nezvimwe.

PLC Programmable Logic Controller: PLC inozivikanwa zvizere se Programmable Logic Controller muChirungu uye programmable logic controller muchiChinese.Inotsanangurwa seyemagetsi sisitimu inoshanda nedhijitari mashandiro, akagadzirirwa chaizvo kushandiswa munzvimbo dzeindasitiri.Inoshandisa kirasi yekurangarira inorongeka yekuchengetedza zvirongwa mukati, kuita mirairo yakatarisana nemushandisi senge zvine musoro mashandiro, sequential control, nguva, kuverenga, uye arithmetic mashandiro, uye kutonga akasiyana marudzi emakanika kana ekugadzira maitiro kuburikidza nedhijitari kana analog yekupinda / kubuda.DCS Distributed Control System: Zita rakazara rechirungu reDCS rinonzi Distributed Control System, ukuwo zita rakazara rechiChinese richinzi Distributed Control System.DCS inogona kududzirwa sechigadzirwa che automated high-tech chinoshandiswa zvakanyanya mumaindasitiri umo mune akawanda analogi loop controls, kuderedza njodzi dzinokonzerwa nekutonga, uye kuisa pakati pekutonga nekuratidzira mabasa.DCS kazhinji ine zvikamu zvishanu: 1: controller 2: I/O bhodhi 3: operation station 4: network network 5: graphics uye process software.
1. Power module, iyo inopa simba rekushanda mukati rekushanda kwePLC, uye vamwe vanogonawo kupa simba rekuisa zviratidzo.
2. CPU module, inova pakati pekugadzirisa unit yePLC, ndiyo musimboti wePLC hardware.Kuita kukuru kwePLC, sekumhanya uye chiyero, kunoratidzwa nekuita kwayo;
3. Memory: Inonyanya kuchengetedza mapurogiramu evashandisi, uye mamwe anopawo imwe ndangariro yekushanda yehurongwa.Zvimiro, ndangariro inosungirirwa kuCPU module;
4. I / O module, iyo inobatanidza matunhu eI / O uye yakakamurwa kuva ma modules ezvinyorwa zvakasiyana-siyana maererano nenhamba yemapoinzi uye rudzi rwedunhu, kusanganisira DI, DO, AI, AO, nezvimwewo;
5. Base plate uye rack module: Inopa chigadziko cheplate yekuisa akasiyana-siyana PLC modules, uye inopa bhazi rekubatana pakati pemamodules.Dzimwe ndege dzinoshandisainterface modules uye vamwe vanoshandisa nzvimbo dzemabhazi kutaurirana.Vagadziri vakasiyana kana marudzi akasiyana ePLCs kubva kumugadziri mumwechete haana kufanana;

6. Nhaurirano module: Mushure mekubatanidza kuPLC, inogona kuita kuti PLC itaure nekombiyuta, kana PLC kuti itaure nePLC.Vamwe vanogonawo kuwana kutaurirana nezvimwe zvinhu zvekudzora, senge frequency converters, tembiricha controller, kana kuumba network yemuno.Iyo yekukurukurirana module inomiririra kugona network kwePLC uye inomiririra chinhu chakakosha chePLC kuita nhasi;

7. Functional modules: Kazhinji, kune yakakwirira-speed counting modules, position control modules, tembiricha modules, PID modules, etc. Aya ma modules ane maCPU avo anogona kutangira kana kutumira zviratidzo zvekugadzirisa kurerutsa PLC CPU kutonga kwezvinhu zvakaoma programmable controls. .Mhando uye maitiro ehungwaru modules zvakare akasiyana zvakanyanya.Kune maPLC ane kuita kwakanaka, aya mamodule ane akawanda marudzi uye kuita kwakanaka.
