Emisebenzini yezimboni—kusukela ezindaweni zokuhlanza uwoyela ezigcina uwoyela ongahluziwe kuya ezindaweni zokusanhlamvu ezilawula ama-silo kakolweni, kanye nezitshalo zamanzi amdaka eziqapha amathangi odaka—ukulinganisa izinga okunembile kubalulekile. Kuqinisekisa ukugcinwa okuphephile, kuthuthukisa ukuphathwa kwempahla, kuvimbela ukugcwala noma ukuhamba okomile, futhi kusekela imisebenzi yokukhiqiza engenamthungo. Kodwa-ke, amathuluzi okulinganisa izinga lendabuko afana nezinzwa ze-ultrasonic, ukushintshana kwe-float, noma ama-pressure transmitter avame ukuba nenkinga ezindaweni ezinzima noma eziyinkimbinkimbi: amasignali e-ultrasonic avinjelwa uthuli noma umhwamuko, ama-float abhajwa oketshezini oluqinile, futhi ama-pressure transmitter ayahluleka emathangini anamazinga okushisa ahlukahlukene noma imithombo ebolile. Ngena ku-transmitter yezinga le-radar engathintani—isisombululo esishintsha umdlalo esinikeza ukunemba okungenakuqhathaniswa kokulinganisa izinga lethangi ne-silo, ngisho nasezimweni ezinzima kakhulu.
Embindini wayo, i-transmitter yezinga le-radar engathintani isebenza ngesimiso se-time-of-flight (ToF). Ikhipha ama-radar pulse avame kakhulu (ngokuvamile angu-24GHz noma angu-80GHz) avela ku-antenna efakwe phezulu kwethangi noma i-silo. Lawa ma-pulse ahamba phansi, abonise ubuso boketshezi, obuqinile, noma obumanzi ngaphakathi, bese ebuyela emuva ku-transmitter. Idivayisi ibala isikhathi esithathwa ama-pulse ukuthi ahambe aye phezulu futhi abuye, bese isebenzisa le datha (kanye nesivinini samagagasi e-radar) ukuze ibale ibanga eliqondile lezinto—lapho ithola khona izinga lamanje. Ngokungafani namathuluzi asekelwe ekuthinteni, ayilokothi ithinte indawo elinganisiwe, isuse ingozi yokuguguleka, ukungcola, noma ukwehluleka kwemishini.
Okuhlukanisa lobu buchwepheshe ukunemba kwabo okuyingqayizivele, isidingo esiyinhloko sezinhlelo zokusebenza zamathangi kanye ne-silo lapho ngisho namaphutha amancane okulinganisa angaholela emiphumeleni ebizayo. Ama-transmitter amaningi angathintani ne-radar aqhosha ngokunemba okungu-±1mm kuya ku-±5mm, kuye ngemodeli kanye nobubanzi bokulinganisa (okungasukela kumamitha angu-0.3 kuya phezulu kwamamitha angu-80). Lokhu kunemba kusebenza ngisho nasezimweni eziguquguqukayo: isibonelo, emathangini kawoyela anezindawo eziguquguqukayo noma ama-silo anezinto ezigelezayo ezifana nesamente noma ama-pellet epulasitiki. Izici ezithuthukisiwe ezifana nokuhlunga i-echo kanye nama-algorithms okucubungula isignali zithuthukisa ukunemba ngokunganaki ukubonakaliswa okungamanga okuvela ezindongeni zamathangi, izakhiwo zangaphakathi (njengezi-agitators noma ama-baffle), noma amafu othuli—izinkinga ezivamile ezihlupha amanye amathuluzi okulinganisa.
Enye inzuzo yama-radar transmitter angathintani ukuthi asebenza ngezindlela eziningi ezindaweni zamathangi kanye nezindawo zokugcina izinto. Aphatha izinhlobo eziningi zemidiya: uketshezi (kufaka phakathi ama-hydrocarbon, amakhemikhali, namanzi), izinto eziqinile (okusanhlamvu, impuphu, nama-pellet), ngisho nama-slurry okunzima ukuwalinganisa (njengodaka lwamanzi angcolile noma imisele yezimayini). Ukwakheka kwawo okuqinile kumelana nezimo ezimbi kakhulu: amazinga okushisa aphezulu (kufika ku-200°C noma ngaphezulu ngamamodeli akhethekile), ukucindezela okuphezulu (kufika ku-100 bar), kanye nemimoya egqwalisayo—okwenza kube kuhle kakhulu ezimbonini ezifana namakhemikhali kaphethiloli, ukudla neziphuzo, kanye nezimayini. Amamodeli amaningi nawo anezilinganiso zokuvikela ze-IP67 noma ze-IP68, okuqinisekisa ukumelana nothuli, amanzi, kanye nomswakama, okubalulekile ezindaweni zokugcina izinto zangaphandle noma ezindaweni zokucubungula ezimanzi.
Kwabasebenzi bezimboni, izinzuzo zidlulela ngale kokunemba nokuqina kuya ekusebenzeni kahle. Ama-radar transmitter angathintani adinga ukulungiswa okuncane: ngaphandle kwezingxenye ezihambayo noma ukuxhumana ne-medium, asikho isidingo sokuhlanza njalo, ukulinganisa, noma ukushintsha izingxenye—ngokungafani nama-float switch adinga ukuseviswa njalo noma ama-pressure transmitter avame ukuvaleka. Aphinde ahlanganiswe kalula nezinhlelo zokulawula ezikhona ngokusebenzisa amaphrothokholi ajwayelekile njenge-Modbus, HART, noma i-analog output engu-4-20mA. Lokhu kusho ukuthi idatha yezinga ingadluliselwa ngesikhathi sangempela ezinhlelweni ze-SCADA, isofthiwe yokuphatha impahla, noma amapulatifomu asekelwe efwini, okuvumela abasebenzi ukuthi baqaphe amazinga kude, basethe izexwayiso ezenzakalelayo zamazinga aphansi/aphezulu, futhi benze izinqumo eziqhutshwa idatha mayelana nokugcwalisa kabusha noma ukuthulula amathangi/ama-silo.
Cabanga nge-elevator enkulu yokusanhlamvu enezindawo eziningi zokugcina ukolweni nommbila. I-transmitter yezinga le-radar engathintani efakwe ku-silo ngayinye inikeza idatha enembile, yezinga lesikhathi sangempela, okwenza indawo ikwazi ukulandelela impahla ngaphandle kokuhlolwa ngesandla (okudla isikhathi futhi okuyingozi). Uma i-silo isondela ekuthwaleni, uhlelo luqala isaziso sokumisa okusanhlamvu okungenayo, kuvimbele ukugcwala. Endaweni yokuhluza uwoyela, ama-radar transmitter emathangini kawoyela ongahluziwe aqinisekisa ukulinganiswa okunembile komthamo ogciniwe, okusekela ukuhambisana nezidingo zokubika zomthetho kanye nokwenza ngcono ukuhlela kokulethwa kwamathangi.
Ekuphetheni, isithumeli sezinga le-radar esingathintani sichaze kabusha ukulinganiswa kwethangi kanye nezinga le-silo. Ukwakheka kwaso okungathintani kususa amaphutha amathuluzi endabuko, ukunemba kwaso okuphezulu kunciphisa izingozi zokusebenza, futhi ukuguquguquka kwaso kuhambisana nezidingo ezahlukahlukene zezimboni. Kumabhizinisi afuna ukuthuthukisa ukuphepha, ukwenza lula ukuphathwa kwempahla, nokuthuthukisa ukusebenza kahle okuphelele, lobu buchwepheshe abuyona nje ithuluzi lokulinganisa—buyimpahla ebalulekile eqhuba ukuthembeka nokukhiqiza emisebenzini yezimboni yanamuhla.
