Gushyiramo ibikoresho bitandukanya ibimenyetso ku makabati yo kugenzura PLC

Mu rwego rwo gukora ikoranabuhanga mu nganda, utubati dugenzura PLC (Programmable Logic Controller) tugira uruhare runini, dushinzwe kwakira ibimenyetso bivuye mu byuma bitandukanye bipima amashanyarazi n'ibikoresho bitera amashanyarazi, no kugenzura neza inzira yo gukora binyuze mu bikorwa by'ikoranabuhanga. Ariko, mu bikorwa bifatika, utubati dugenzura PLC dukunze guhura n'ibidukikije bitandukanye bigoye bya electromagnetic hamwe n'ibibazo byo kubangamira ibimenyetso, bishobora gutera imikorere mibi ya sisitemu yo kugenzura, guhomba kenshi, ndetse no guteza akaga ku mutekano w'ibikoresho n'abakozi. Kubwibyo, hongerwamo ikimenyetso cyakuwe ukwacyoAtors kuri PLC control cabinet byabaye igisubizo rusange.

Imirimo y'ingenzi y'ibikoresho bitandukanya ibimenyetso birimo gukumira kohereza kwangirika kwa electromagnetic interference, kugabanya kubaho kwangirika kwa sisitemu, no gutanga uburyo bwo kwitandukanya mu gihe ibikoresho byangiritse aho biri, gukumira gukwirakwira kw'amakosa kuri sisitemu yose yo kugenzura. Mu guhindura no guhindura ibimenyetso byakiriwe na PLC binyuze mu bikoresho bya semiconductor, hanyuma bikavangura no kubihindura hakoreshejwe ibikoresho byo kumenya optique cyangwa magnetic sensing, hanyuma bigasubiramo no kubihindura ku kimenyetso cy'umwimerere cyangwa ibimenyetso bitandukanye, iyi nzira ishimangira ko ikimenyetso gihamye kandi cy'ukuri, mu gihe kandi birinda kwangirika kwa PLC no kugabanya ingaruka z'ibimenyetso biri aho biri kuri PLC, cyane cyane ibimenyetso by'akajagari. Byongeye kandi, ibikoresho bitandukanya ibimenyetso bishobora no guhindura ibimenyetso, nko guhindura ibimenyetso bivuye ku miyoboro ya PT10 bikajya mu bimenyetso bya 4-20mA no kubishyira muri sisitemu za PLC, birinda neza amakimbirane hagati y'amashanyarazi n'amasoko y'amashanyarazi no gukemura ikibazo cyo kubangamirana hagati y'imirongo n'ibikoresho.

Mu bikorwa byihariye, nko mu murongo w’umusaruro w’uruganda rw’icyuma, gupima no kugenzura bigerwaho binyuze muri PLC, ibikoresho byo kwihutisha ibikorwa, n’ibikoresho byo kwihutisha ibikorwa. PLC ishyirwa mu kabati k’ubugenzuzi kari muri metero magana menshi uvuye aho ikorera (ikora ku bushyuhe bw’icyumba), n’ibikoresho byo kwihutisha ibikorwa cyangwa thermocouples bivuye aho ikorera ibimenyetso bisohoka binyuze mu nsinga bijya mu kabati k’ubugenzuzi mu cyumba cy’ubugenzuzi. Muri iki gihe, ikimenyetso cyinjira muri PLC kigomba gukurwaho kandi gishobora no gukenera guhindurwa, nko gutandukanya 4-20mA no kuyihindura 0-5V mbere yo kwinjira muri PLC. Ibikoresho birangiza gutandukanya no guhindura ibimenyetso bya thermocouple byitwa "thermocouple signal isolator" cyangwa "thermocouple temperature transmitter". Akazi kayo k’ingenzi karimo gutandukanya ikimenyetso cyinjiye n’ikimenyetso cy’ibisohoka, ndetse no guhindura ikimenyetso cy’urwego rwa mV cyinjiye kiva muri thermocouple kikajya mu bimenyetso bisanzwe by’inganda (4-20mA, 0-5V, 0-10V).

Muri make, gushyiraho ibyuma bitandukanya ibimenyetso bifite akamaro kanini mu kunoza imikorere y’imikorere y’inganda, kugabanya igipimo cyo gutsindwa, kurinda ibikoresho bya PLC, no kunoza ubwiza bw’ibimenyetso. Ni kimwe mu bintu by’ingenzi mu gutuma imikorere y’ibipimo ihamye kandi yizewe yabyo.
