I-plc, i-DCS, i-FCS: I-FCS: I-FCS

Kwindawo yokulawula imizi-mveliso, ukuqonda umahluko kunye nobudlelwane phakathi kwee-Plcs, iDCSs, kunye ne-FCS ibalulekile. Nantsi iqhekeza elineenkcukacha:

Amagqabantshintshi nge-PLC, DCS, kunye neFCS

• I-PLC (i-Logic eququzelekileyo ye-Logic):Ukuphakanyiswa kwiNkqubo yokuLawula i-DREAY, ii-PLCs zizixhobo ze-elektroniki ezilungiselelwe ukuba zihenyuzwe kwaye zenziwe ngemveliso ezenziwe ngemveliso. Basebenzisa inkumbulo enokufikeleleka ukugcina imiyalelo yokwenza imisebenzi esengqiqweni, ukuvumela ukulawulwa kweenkqubo ezahlukeneyo zemveliso kunye nemveliso.

• I-DCS (inkqubo yolawulo ethunyelweyo):Ukuvela nge-1970s njengezikali zemveliso eyandisiweyo kunye neemfuno zokulawula ukwanda, idilesi ye-DCSS imida yeenkqubo zeNkqubo elawula izinto ezikumgangatho. Babonisa ubume be-hierarchical ngolawulo oluphakathi kunye nolawulo oluphakathi, ludibanisa itekhnoloji yoqeqesho oluninzi njenge-elektroniki, iikhompyuter kunye nonxibelelwano.

• I-FCS (inkqubo yokulawula intsimi):Inkqubo entsha-yokulawula imizi-mveliso ye-1990, i-FCS isebenzisa itekhnoloji yendawo yokudibanisa izixhobo kunye nabalawuli, ukudala inkqubo yonxibelelwano yedijithali, ezimbini eziphumelela ngokufanelekileyo kwimisebenzi yolawulo.

I-FCS kunye ne-DCS uthelekiso

UPhuhliso kunye nokudityaniswa: I-FCS ivela kwi-DCS kunye neetekhnoloji ze-PLC, ibandakanya iimpawu zabo ngelixa usenza inkqubela phambili yotshintsho. I-DCSS yanamhlanje kunye nee-PLCs ziguquka ekusebenzeni, kunye ne-DCSS ifumana amandla olawulo olungqalileyo kunye nee-PLCs ezivaliweyo - uLawulo lweLoop. Zombini zinokwenza uthungelwano olukhulu kakhulu, olukhokelela ekugqityweni kwezicelo zabo.

Ezona mpawu :

• Unxibelelwano:Kwii-DCS, ibhasi yedatha isebenza njengomqolo, kunye noyilo lwenkqubo yokuguquguquka kwenkqubo kunye nokhuseleko. Uninzi lwabathengisi be-DCS banikezela ngeebhasi zedatha abangafunekiyo kwaye basebenzise iiprothokholi zonxibelelwano ezintsonkothileyo kunye nempazamo-yokujonga iindlela zokujonga. Iindlela zonxibelelwano ziquka iindlela ze-synchronous kunye ne-asynchnnshrononous.

• Ulwakhiwo:I-DCS ihlala isebenzisa i-on-uqhagamshelo olunye olwenziwayo kunye nokudluliselwa kwesibonakaliso esinye, ngelixa i-FCS isebenzisa enye - ukunxibelelana okuninzi kunye nokudluliselwa kwesikhombisi.

• Ukuthembeka:I-FCS ineendlela ezingcono zokudluliselwa kosulelo lwedijithali kunye nezakhono zokuphazamiseka kunye nokuchaneka okuphezulu. Ngokwahlukileyo, i-DCS isebenzisa imiqondiso ye-analog eqhelene nokuphazamiseka kwaye ichanekile.

• Ukulawulwa kokukhuthazeka:I-FCS ifezekisa ngokupheleleyo imisebenzi yolawulo kwizixhobo zasemzileni, ngelixa i-DCS ifakwe ngokuyinxenye.

• Isixhobo:I-FCS isebenzisa izixhobo ezikrelekrele nonxibelelwano lwedijithali kunye nezakhono zokulawula, ngelixa i-DCS ixhomekeke kwizixhobo ze-alog ezinemisebenzi encinci.

• Iindlela zonxibelelwano:I-FCS yamkela indlela yedijithali yedijithali, i-bi - i-bi - i-bi - i-bi - i-bi - i-bi - i-bi - i-bi - i-bi-bi kuwo onke amanqanaba, ngelixa i-DCS inolwazi lwe-hcbrid ngonxibelelwano lwedijithali kwimibhalo ephezulu kunye nemiqondiso ye-analog kwinqanaba lentsimi.

• Ukusebenzisana:I-FCS ivumela ukunxibelelana ngokulula kunye nokudibana kwezixhobo ezivela kubathengisi abahlukeneyo kusetyenziswa umgangatho ofanayo wecandelo, ngelixa i-DCS inenziwa ngokubambisana ngokungafanelekanga ngenxa yeeprotokholi zonxibelelwano zamandla.

I-PLC kunye ne-DCS uthelekiso

Plc:

• Ukuvela kwendalo:Ii-PLCs ziye zavela kulawulo lokutshintsha ukuba zilawule ngokulandelelana kunye nokulungiswa kwedatha, kwaye ngoku zibandakanya ulawulo lwe-PID oluqhubekayo, ngemisebenzi ye-PID ephakathi kwizikhululo eziphazamisayo. Banokwenza uthungelwano lwe-PLC ngenye i-PC njengesikhululo esikhulu kunye nee-PLCs ezininzi njengezikhululo zamakhoboka, okanye nge-plc enye njengeNkosi kunye nabanye njengamakhoboka.

• Imeko yesicelo:Ii-PLCs zisetyenziselwa ngokuyintloko kulawulo olulandelelanayo kwiinkqubo zemizi-mveliso, kwaye ii-SELCs zale mihla ziphathelele kulawulo lwe-loop.

I-DCS:

• Ukudityaniswa kobugcisa:I-DCS idibanisa i-4C (unxibelelwano, ikhompyuter, iKhompyuter, itekhnoloji ye-CRT yokujonga nokulawula. Inika umthi-njenge-topology kunxibelelwano njengeyona nto iphambili.

• Uyilo lwenkqubo:I-DCS inamanqanaba amathathu aqukayo (Isikhululo senjini), ukusebenza (isikhululo se-ongertor), kunye nezixhobo zentsimi (isikhululo sentsimi). Isebenzisa imiqondiso ye-analog nge-A / D - D / Inguquko kunye nokudityaniswa koor. Isixhobo ngasinye siqhagamshelwe ngokusebenzisa umgca onikezelweyo kwi-I / O, enxibelelene ne-LAN ngeSikhululo soLawulo.

• Amasimiselo:I-DCS ilungele ukuqhutywa kwenkqubo enkulu yokuqhubeka kwenkqubo, enjengakwimizi-mveliso yePetrochemical.

Ukuqonda ezi nkqubo kuyanceda ukukhetha itekhnoloji yelungelo leProjekthi yeMizi-mveliso.
