Kugadziriswazve kwenetwork nekushandisa ring setups kana PRP kunoita kuti masisitimu arambe achishanda pasina kana nguva yekumira kana chimwe chinhu chikatadza kushanda.
Kuvimbika kwechiratidzo uye matanho ekuchengetedza cyber zvinobatsira kuchengetedza system yako yekudzora kubva kuzvikanganiso.
Zvikamu Zvikuru zveIndasitiri yeOtomatiki uye Masisitimu Ekudzora
Sisitimu yega yega yekudzora otomatiki yakavimbika inotsamira pazvikamu zvina zvehardware: masensa, ma actuator, ma controllers, uye human machine interface inovabatanidza pamwe chete. Sarudzo dzako pane izvi zvikamu zvinosarudza kana otomatiki yako yeindasitiri uye masisitimu ekudzora anoshanda kwemakore kana kuti akakundikana mukati memwedzi. Chikamu chimwe nechimwe chinofanira kushanda nezvimwe, uye chimwe nechimwe chinoda kusarudzwa kwakanyatsorongeka zvichienderana nenzvimbo yako chaiyo.
MaSensor, Actuators, uye Vatongi
MaSensor anounganidza data kubva mukuita kwako. MaActuator anoita mabasa epanyama. MaController, akadai se programmable logic controllers (PLCs) kana masisitimu ekudzora akaparadzirwa (DCS), gadzirisa data uye mirairo yekuburitsa. Dhizaini yako yemasisitimu ekudzora otomatiki inofanirwa kutsanangura mamiriro ezvinhu akaomarara ari mumafekitori.
Kusagadzikana kwezvakatipoteredza kunowanzo paradzanisa zvinhu zvinovimbika kubva mukukundikana kunogara kuripo. Funga nezvezvinhu izvi pakusarudza masensa nema actuator:
Kupisa kwakanyanya, nharaunda dzine ngura, uye mamiriro ekuzunguzika zvakanyanya zvinoda magadzirirwo emagetsi akagadzirwa nehunyanzvi.
Kudzivirira hunyoro, guruva, uye mamiriro ekunze zvinoda dzimba dzakavharirwa, zvinhu zvisingapindi ngura, uye machira ekudzivirira.
Kuyera nzvimbo dzakavharirwa zvichienderana nezvinodiwa neNEMA uye mirairo yeATEX yemhepo inoputika inoita kuti pave nekuchengetedzwa kwakakodzera kwezvakatipoteredza.
Zvinhu zvinogara kwenguva refu, zvakaita sekuvaka kwakasimba uye nzira dzekusimbisa dzakakosha, zvinowedzera hupenyu hwebasa mumamiriro ezvinhu akaoma.
Tanga magadzirirwo e sensor yako nekutarisa mamiriro ekunze, kwete kutarisa katalogi. Nyora pasi kumanikidzwa kwemvura, kupisa kwakanyanya, makemikari akawandisa, uye maEMI sources. Iyi nzira inodzivirira zvikanganiso zve magadzirirwo zvinokonzeresa kutadza kushanda zvakanaka kwenzvimbo.
Kururama kwemasaini kunokanganisa zvakananga kunaka kwekudzora mashandiro ako. Masisitimu eanalog needhijitari akasiyana zvakanyanya :

Izvi zvinoderedza frequency yewachi uye zvinovandudza signal integrity. Over-terminating differential mode impedance pa receiving end inoita kuti eye-opening characteristics ive nani. Nzira idzi dzinobatsira ma control systems ako kuchengetedza kutaurirana kwakavimbika. Kuva nechokwadi chekuti kutaurirana kwakavimbika ndicho chinhu chakakosha pakudzora maitiro.
Kugadzirisa Kuchengetedzwa KwepaIndaneti uye Kubatanidzwa Kwenhaka
"Kuva nematanho akawanda ekudzivirira kunowanzo tendeka. Kukundikana kamwe chete kunogona uye kuchakundikana."
Pfungwa iyi inotungamira mashandisirwo aunoita maindasitiri ako ekugadzirisa otomatiki uye masisitimu ekudzora kubva mukutyisidzira kwecyber. Tanga kuisa kuchengetedzeka mukugadzira kubva pakutanga chaipo. Shandisa network segmentation uye DMZs kuti uchengetedze michina yekare yeSCADA yakasiyana neIT yekambani uye masisitimu akabatana neinternet. Shandisa mamwe ma control akadai se protocol-aware intrusion detection, bvumira software inotenderwa chete paHMIs, uye ita kuti historical interfaces iverengwe chete. Kuti uwane mukana wakachengeteka wekure, shandisa jump servers dzine multi-factor authentication, session recording, uye permissions dzine nguva shoma.
Kana uchiwedzera hardware itsva kumasisitimu ekare, shandisa kugadziridzwa kwakavakirwa panjodzi nematurusi akaita seCyber-PHA kana CyberHAZOP kuti utarise pane shanduko dzakakosha, uye unyatsoteerera kuti zvinhu zvinobatana sei. Tevedzera mitemo yakaita seIEC 62443 kuti uronge kukwidziridzwa kwakachengeteka. Sarudza.

FAQ
Ndeupi musiyano uripo pakati pemitemo yekuchengetedza yeSIL nePL?
SIL (IEC 62061) inoshandiswa mumaindasitiri ekugadzira zvinhu zvakaita semafuta negesi. PL (ISO 13849) inoshandiswa pamichina. Zvese zvinokubatsira kugadzira sisitimu yako yekudzora. Mashandisirwo ako emagetsi emuindasitiri anofanira kusvika padanho rekuchengetedza rinodiwa.
Unosarudza sei pakati pe PLC uye DCS?
Shandisa a PLC pakudzora michina imwe chete. Shandisa DCS yekudzora maitiro anoshanda nguva dzese. Maindasitiri ako ekugadzirisa otomatiki uye masisitimu ekudzora angangoda chimwe kana chimwe. Masisitimu ese ari maviri ekudzora anobatanidzwa kumasensa nemaactuator.
Ndeipi network topology inoshanda zvakanyanya kune otomatiki yakavimbika?
Kugadziriswa kweringi ne "redundancy" kunoita kuti munhu akwanise kupora nekukurumidza mushure mekukundikana. Kugadziriswa kweStar kunodzivirira kuti kutadza kwemudziyo kusapararire. Sisitimu yako yekudzora inoshanda zvirinani nesarudzo iyi. Kugadziriswa kweindasitiri kunoda kutariswa kwakanaka kwehutano hwenetwork.
Ungaderedza sei kukanganiswa kwemasaini mu control panel?
Chengeta tambo dzemagetsi nedzechiratidzo dzakaparadzana. Shandisa tambo dzine waya dzakakombama uye dzinodzivirira zvakanaka. Batanidza nzvimbo dzese panzvimbo imwe chete. Matanho aya anoita kuti zvinhu zvishande zviri nani. Anoita kuti masisitimu ekudzora eindasitiri ave akavimbika.
Ndezvipi zvakanakira dhizaini yemodular kune system yako?
Dhizaini yemodular inokutendera kuti uwedzere zvikamu apo sisitimu ichiri kushanda. Zvinoita kuti zvive nyore kuwedzera zvikamu zvitsva. Zvinotora nguva shoma kuronga. Inoshanda nemaSCADA systems. Sisitimu yako ye automation inobatsirwa nemhinduro idzi dze industrial automation.
