Zvakakosha Plc ruzivo rwe auto

Mudenga rekugadzira maindasitiri uye kufambira mberi kwehunyanzvi, PLCS (yakarongwa logic vanodzora) vanotamba basa rakakosha mukudzora automation. Iyo PLC inogona kunzwisiswa zvakanyanya seyakavharwa yekudzosera mari yekuwedzera kudzora. Mune zvinoshanda zvinoshanda, plcs zvinoderedza zvakanyanya kuderedza maindasitiri ekudzora mari uye kusimudzira manejimendi manejimendi uye automation. Kuna Master PLCS, munhu anofanira kutanga atanga kuziva ruzivo rwekutanga.

PLC zvikamu uye mabasa avo

Pamusoro peCPU, memory, uye kutaurirana nzvimbo, maplcs vane maincoque uye anobuda mitezo zvine chekuita nenzvimbo dzekushanda.

1. Input interface: inogamuchira masaini kubva kune yakadzorwa zvishandiso uye inotyaira matunhu emukati kuburikidza neopicocouple uye yekuisa matunhu.

2. Output interface: Transmits chirongwa kuuraya zvinokonzerwa kuburikidza neoptocouplers uye zvinobuda zvikamu (zvinotevera, vatariri veKorasitors, vanotsauka) kudzora mitoro yekunze.

Basic plc unit uye zvikamu zvacho

Iyo yekutanga plc yunivhesiti ine akati wandei zvakakosha zvikamu:

1. CPU: Iyo Core yeiyo PLC, kutungamira akasiyana mashandiro akadai sekugamuchira zvirongwa zveMushandisi uye data, Diagnostics, uye kuuraya chirongwa.

3. REALY BUDAT Mhando: Inoenderana neese AC uye DC mitoro, asi ine nguva yakareba yekupindura nguva uye yakaderera yekushandisa frequency.

PLC mhando dzemhando uye zvadzo

Plcs inogona kuiswa mumhando nhatu dzekugadzira:

1. Typel Tyral Type: Nesimba, uye I / O / O / O / Type iyi yakaenzana uye mutengo - inowanzo shandiswa muzvikamu zvidiki - zviyero zvekutanga.

2. Mhando yeModular: Zvimiro zvinoparadzanisa mamai emabasa akasiyana, zvinopa shanduko inochinjika uye nyore kuwedzera uye kugadzirisa. Izvo zvinowanzo shandiswa pakati nepakati - uye hombe

3. Typeable Type: Inosanganisa iyo maficha emhando dzekubatanidza uye dzeModular. Iyo CPU, SIMBA SUPLY, uye i / O / O misangano yakazvimirira module yakabatana nemabhuruku, inoverengera inoshanduka inoshanduka uye saizi yemuchinjiki.

PLC SCAN kutenderera uye kufurira kwayo zvinhu

Iyo plc scan kutenderera inosanganisira matanho mashanu: Yemukati yekugadzirisa, yekukurukurirana basa, yekuisa kugadzirisa, kuuraya chirongwa, uye kugadzirwa kwekubuditsa. Iyo nguva inodiwa kuti upedze aya mashanu kamwe chete inonzi scan kutenderera. Iyo inokanganiswa neiyo CPU's Yekushandisa Yekumhanya, PLC Hardware inogadziriswa, uye kureba kwechirongwa chemushandisi.

PLC chirongwa chekuuraya nzira uye maitiro

Plcs Execute mushandisi zvirongwa uchishandisa cyclic scaning nzira. Maitiro ekuuraya anosanganisira matanho matatu: Input sampling, kuuraya chirongwa, uye kuburitsa zororo.

Zvakanakira zvePLC kutonga kweSystems pamusoro pekudzokorora kudzora masisitimu

1. Maitiro ekudzora: PLCS Shandisa hurongwa hwekudzora, uchibvumira kushandurwa kuri nyore kana kuwedzera kwekutonga zvinodiwa, nemafambisirwo asina muganho.

2. Kushanda Mode: PLCS inoshanda mune serial mode, kuvandudza iyo inorwisa system - yekukanganisa kugona.

3. Dzivirira Speed: PLC Contaces zvakanyanyisa zvinokonzeresa kuraira kwekurairwa kuurayiwa muMicoseconds.

4. Nguva uye kuverenga: PLCS Shandisa Semiconductor yakasanganiswa matunhu seyakagadzirwa yakapihwa neCrystal Oscilloctors, inopa yakakwira nguva chaiyo uye Wide - Ranging Capiting Capiting. Ivo zvakare vane kuverenga mabasa hakuwanikwe muzvinyorwa zvekare.

5. Kuvimbika uye Kuchengetedza: PLCS Shandisa MicroelectRocial Technology uye Inoratidza Kuzvibata - Kuongorora Mabasa Ekuwanikwa Kwakakosha Kanganiso.

Zvinokonzeresa zvePLC Exput mhinduro Lag uye mhinduro

PLCS inoshandisa centraled sampling uye kubuda cyclic scanning. Nhamba dzekupinza dzinongoverengwa panguva yekuisa sampling chikamu chega chega chechiteshi chechiteshi, uye kuurayiwa kweProgram Pamusoro pezvo, kupinda uye kuburitsa kunonoka uye mushandisi chirongwa chekureba kunogona kukonzera kuburitsa mhinduro yeLag. Kusimudzira I / O Prindance Speed, mumwe anogona kuwedzera kuwanda kwekuisa sampling uye overput Sampling Sampling

PLC sarudzo yekufungisisa

1. Sarudzo yemuenzaniso: Fungidzira zvinhu zvakadai seyakagadzirwa, nzira yekuisa, inoshanda zvinodiwa, mhinduro yekumhanyisa, kuvimbika, uye kufanana kwekuenzanisa.

2. Kusarudzwa kwekugona: Kubva pane i / o mapoinzi uye mushandisi memory kugona.

3. I / o module sarudzo: inovhara switching uye analog i / o module pamwe neakakosha - basa modules.

4. Simba rekupa module uye humwe kusarudzwa kwekushandisa: senge zvirongwa zvekuronga.

Hunhu hwePLC Centraled sampling uye kubuda kushanda mode

Mukuremedza sampling, chimiro chekuisa sampled chete panguva yekuisa sampling chikamu chechiteshi chechiteshi, uye magumo ekupedzisira akavharirwa panguva yekuuraya chirongwa. Mukukwira kwepasirese, iyo yekuburitsa Refresh chikamu ndiyo nguva iyo iyo mamiriro ari mugwaro rekubuditsa logy hunotamiswa kune iyo yekubuditsa latch yekuburitsa iyo yekubuditsa iyo yekubuditsa interface. Iyi nzira yekushanda inovandudza iyo Inti yeSystems Inti - Kuvhiringidza kugona uye kuvimbika asi kunogona kukonzera mhinduro / yekuburitsa mhinduro yeLag muPLCS.

Plc inoshanda mode uye maficha

PLCS inoshanda uchishandisa Centraded Sampling Sampling Sampling Sampling Sampling Sampling Sampling Sampling Sampling Sampling Sampling Sampling Sampling Sampling Sampling Sampled, uye Cyclic Scanning. Sampled sampling inoreva kuti Inting Status inongori chete panguva yekuisa chikamu chekusangana kwekutanga kwekutenderera kwekutenderera, nekupedzisira kuguma kwakavharirwa panguva yekuuraya chirongwa. Centraled inobuda inoreva kuendesa kwekubuda kwekubuda - zvine hukama kubva kune yekubuditsa logy image kunyoresa kune iyo yekubuda kunze kwekutanga kwekuzorodza chikamu chekuzorora. Cyclic Scanning inosanganisira kuuraya akawanda mashandiro mukutenderera kwekutenderera kuburikidza nenguva - kupatsanurana kutevedzana.

Kuumbwa uye kushanda nheyo yeElectromagnetic vatauri

Electromagnetic contages ine electromagnic mechanisms, vatevedzani, arc - yekudzima midziyo, sunungura michina yemuchina, uye zvikamu zvimisikidzo. Kana iyo Electromagnetic Coil, iyo iripo inounza munda wemaginhini, ichikonzera iyo station iron core yekugadzira electromagnetic Suction inokwezva iyo Armature uye inotora mafambisirwo. Izvi zvinokonzeresa zvinovharirwa zvekuvhara kuvhura uye kazhinji zvakavhurika vatinosangana navo kuvhara. Kana iyo coil is de - inosimbiswa, iyo Electromaggnic simba rinonyangarika, uye ruoko rwunosunungurwa neiyo tsime, kudzoreredza mafambiro kune yavo yekutanga mamiriro.

Tsanangudzo yeProgrammable Logic Controllers (PLCS)

Iyo PLC mudziyo wedhijitari yemagetsi yakagadzirirwa nzvimbo dzeindasitiri. Inoshandisa ndangariro inoratidzwa yekuchengetedza mirayiridzo yekuita zvine musoro, kutevedzera, nguva, kuverenga, uye arithmetic mashandiro. Inodzora akasiyana mashini kana maitiro ekugadzira kuburikidza nedhijitari kana analog input / kubuda.

Plcs uye zvine chekuita nePeripheral zvishandiso zvakagadzirirwa kubatanidza nyore nyore nekudzivirira kwemaindasitiri uye kufambisa kushanda.
