I-Industrial “Brain” PLC: Uguquko olungabonakaliyo lwe-Machine Automation

Kwiiworkshop ezigqumayo zeefektri zanamhlanje, iibhokisi zesinyithi ezingenamkhethe zilawula ngokuzolileyo ukusebenza ngokuchanekileyo koomatshini abaninzi. Ezi ziiProgrammable Logic Controllers (PLC)—iingqondo eziphambili ze-automation yemizi-mveliso.

Emva kokusebenza ngocwangco kweukufakwa kwelayiniumatshini okanyeukufaka i-liner kunye ne-hemmingumatshini, ikhompyutha yemizi-mveliso eyaziwa ngokuba yiProgrammable Logic Controller (PLC) ilawula kwaye ilungelelanisa yonke into.

01 Yintoni i-PLC?

I-PLC sisifinyezo se-Programmable Logic Controller. Yikhompyutha yedijithali eyenzelwe ngokukodwa iindawo zoshishino, esetyenziselwa ukwenza ulawulo lwezixhobo zoomatshini kunye neenkqubo zemveliso zibe zezona zizenzekelayo.

I-PLC ngokuyintloko iqulathe iYunithi yokuCwangcisa ePhakathi (i-CPU), iimodyuli zokufaka, iimodyuli zokukhupha, izixhobo zokucwangcisa, kunye neemodyuli zombane. Ifezekisa imisebenzi ezenzekelayo ngokuqhubekeka ngokuskena imiqondiso yokufaka, ukusebenzisa i-logic yenkqubo, kunye nokuhlaziya ulawulo lwemveliso.

02 Idlala Njani Indima Ephambili?

I-PLC inokulawula ulawulo lwentshukumo, isebenzisa iimodyuli ezikhethekileyo kunye nemiyalelo yokulawula ngokuchanekileyo indawo, isantya, kunye nokukhawuleziswa kweentshukumo ezithe tye okanye ezijikelezayo. Oku kubaluleke kakhulu kumatshini wokuhlanganisa kunye neerobhothi.

I-PLC ikwavumela ulawulo lwenkqubo ye-closed-loop, yenza ulawulo lwe-PID closed-loop kwiimilinganiselo ze-analog ezitshintsha rhoqo ezifana nobushushu, uxinzelelo, kunye nesantya sokuhamba, ukuqinisekisa uzinzo lweenkqubo zemveliso.

 03 Uluhlu olubanzi lwezicelo

I-PLC zisetyenziswa kakhulu kwi-automation yemizi-mveliso, zigubungela iinkalo ezininzi.Okwangoku,ukufakwa kwe-liner yethuumatshini okanyeukufaka i-liner kunye ne-hemmingumatshini ukubandakanya iinkqubo ze-PLC, nto leyo ephucula kakhulu ukusebenza kakuhle kwemveliso kunye nokunciphisa iindleko zabasebenzi.

Konke oku kubonisa ukuba ii-PLC, njengezona zinto ziphambili eziqhuba ukwenziwa kwezinto ngokuzenzekelayo kwimizi-mveliso, zihlala ziqhubela phambili ishishini lokuvelisa ukuze lisebenze kakuhle, libe nobukrelekrele, kwaye lizinze.
