Kwimisebenzi yemizi-mveliso—ukusuka kwiindawo zokucoca ioyile ezigcina ioyile eluhlaza ukuya kwiindawo zokugcina iinkozo ezilawula ii-silos zengqolowa, kunye nezityalo zamanzi amdaka ezijonga iitanki zodaka—ukulinganisa ngokuchanekileyo kwinqanaba kubalulekile. Kuqinisekisa ukugcinwa okukhuselekileyo, kuphucula ulawulo lwempahla, kuthintela ukugcwala okanye ukuhamba okomileyo, kwaye kuxhasa imisebenzi yemveliso engenamthungo. Nangona kunjalo, izixhobo zokulinganisa kwinqanaba zemveli ezifana nee-ultrasound sensors, ii-float switches, okanye ii-pressure transmitters zihlala zisokola kwiindawo ezinzima okanye ezinzima: imiqondiso ye-ultrasonic ivalwe luthuli okanye ngumphunga, ii-float zibambeka kulwelo oluxineneyo, kwaye ii-pressure transmitters ziyasilela kwiitanki ezinamaqondo obushushu ahlukeneyo okanye imidiya ebolileyo. Ngena kwi-transmitter yenqanaba le-radar engadibaniyo—isisombululo esitshintsha umdlalo esinika ukuchaneka okungenakuthelekiswa nanto kokulinganisa inqanaba letanki kunye ne-silo, nokuba kwiimeko ezinzima kakhulu.
Embindini wayo, i-transmitter yenqanaba le-radar engadibaniyo isebenza ngokomgaqo wexesha lokubhabha (i-ToF). Ikhupha ii-radar pulses eziphezulu (ngesiqhelo i-24GHz okanye i-80GHz) ezivela kwi-antenna ebekwe phezulu kwitanki okanye kwi-silo. Ezi pulses zihamba ziyehla, zibonise umphezulu wolwelo, oluqinileyo, okanye olumdaka ngaphakathi, kwaye zibuyele kwi-transmitter. Isixhobo sibala ixesha elithathwayo ukuba ii-pulses zihambe ziye kumphezulu zize zibuye, emva koko sisebenzisa le datha (kunye nesantya samaza e-radar) ukubala umgama ochanekileyo kwizinto—apho ifumana khona inqanaba langoku. Ngokungafaniyo nezixhobo ezisekelwe kudibaniso, ayichukumisi medium elinganisiweyo, isusa umngcipheko wokuguguleka, ungcoliseko, okanye ukusilela koomatshini.
Okwenza obu buchwephesha bahluke kakhulu kukuchaneka kwayo okugqwesileyo, imfuneko ephambili yokusetyenziswa kweetanki kunye ne-silo apho iimpazamo ezincinci zokulinganisa zinokukhokelela kwimiphumo ebiza kakhulu. Uninzi lwee-transmitters ze-radar ezingadibaniyo ziqhayisa ngokuchaneka kwe-±1mm ukuya kwi-±5mm, kuxhomekeke kumzekelo kunye noluhlu lokulinganisa (olunokuthatha ukusuka kwi-0.3 yeemitha ukuya phezulu njengeemitha ezingama-80). Oku kuchaneka kuyasebenza nakwiimeko eziguquguqukayo: umzekelo, kwiitanki zeoyile ezineendawo eziguquguqukayo okanye ii-silos ezinezixhobo ezigelezayo ezifana nesamente okanye ii-pellets zeplastiki. Iimpawu eziphambili ezifana nokucoca i-echo kunye ne-algorithms yokucubungula isignali ziphucula ngakumbi ukuchaneka ngokungahoyi ukubonakaliswa okungachanekanga okuvela kwiindonga zeetanki, izakhiwo zangaphakathi (ezifana nee-agitators okanye ii-baffles), okanye amafu othuli—iingxaki eziqhelekileyo ezichaphazela ezinye izixhobo zokulinganisa.
Enye inzuzo yezixhobo zokuhambisa iradar ezingadibaniyo kukuguquguquka kwazo kwiindawo ezihlala iitanki kunye neendawo ezihlala iitanki. Ziphatha uluhlu olubanzi lwezixhobo zokusasaza: ulwelo (kuquka iihydrocarbon, iikhemikhali, kunye namanzi), izinto eziqinileyo (iinkozo, iipowders, kunye neepellets), kwanezibi ezinzima ukuzilinganisa (ezifana nodaka lwamanzi amdaka okanye iingceba zemigodi). Uyilo lwazo oluqinileyo lumelana neemeko ezinzima: amaqondo obushushu aphezulu (ukuya kuthi ga kwi-200°C nangaphezulu ngeemodeli ezikhethekileyo), uxinzelelo oluphezulu (ukuya kuthi ga kwi-100 bar), kunye neemeko ezirhabaxa—okuzenza zilungele amashishini afana neekhemikhali zepetroli, ukutya neziselo, kunye nemigodi. Iimodeli ezininzi ziza nemilinganiselo yokhuseleko lwe-IP67 okanye i-IP68, ukuqinisekisa ukumelana nothuli, amanzi, kunye nokufuma, okubalulekileyo kwiindawo ezihlala iitanki zangaphandle okanye kwiindawo zokucubungula amanzi.
Kwabasebenzi bemizi-mveliso, iingenelo zidlulela ngaphaya kokuchaneka nokuqina ukuya ekusebenzeni kakuhle. Iitransmitter zeradar ezingadibaniyo zifuna ulondolozo oluncinci: ngaphandle kweendawo ezishukumayo okanye ukudibana nesixhobo, akukho mfuneko yokucoca rhoqo, ukulinganisa, okanye ukutshintshwa kwenxalenye—ngokungafaniyo neeswitshi ezidadayo ezifuna ukulungiswa rhoqo okanye iitransmitter zoxinzelelo ezidla ngokuvaleka. Zikwadibaniswa ngokungenamthungo neenkqubo zolawulo ezikhoyo ngeenkqubo eziqhelekileyo ezifana neModbus, HART, okanye i-4-20mA analog output. Oku kuthetha ukuba idatha yenqanaba inokudluliselwa ngexesha langempela kwiinkqubo ze-SCADA, isoftware yolawulo lwempahla, okanye amaqonga asekelwe kwilifu, okuvumela abasebenzi ukuba bajonge amanqanaba bekude, babeke izilumkiso ezenzekelayo zamanqanaba aphantsi/aphezulu, kwaye benze izigqibo eziqhutywa yidatha malunga nokuzalisa okanye ukukhupha iitanki/ii-silos.
Cinga nge-elevator enkulu yeenkozo enee-silos ezininzi ezigcina ingqolowa nombona. I-transmitter yenqanaba le-radar engadibaniyo efakwe kwi-silo nganye inika idatha echanekileyo, yexesha langempela, evumela ukuba isikhungo silandelele uluhlu lwezinto ngaphandle kokuhlolwa ngesandla (okuthabatha ixesha kwaye kuyingozi). Ukuba i-silo isondela kumthamo, inkqubo ibangela isilumkiso sokumisa ukutya okungenayo, okuthintela ukugcwala. Kwindawo yokuhluza ioyile, ii-transmitter ze-radar kwiitanki zeoyile ekrwada ziqinisekisa ukulinganiswa ngokuchanekileyo komthamo ogciniweyo, zixhasa ukuthotyelwa kweemfuno zengxelo ezilawulayo kunye nokwenza ngcono ucwangciso lokuhanjiswa kweetanki.
Ukuqukumbela, i-transmitter yenqanaba le-radar engadibaniyo ichaze ngokutsha umlinganiselo wetanki kunye nenqanaba lesilo. Uyilo lwayo olungadibaniyo lususa iimpazamo zezixhobo zemveli, ukuchaneka kwayo okuphezulu kunciphisa iingozi zokusebenza, kwaye ukuguquguquka kwayo kuyahambelana neemfuno ezahlukeneyo zoshishino. Kumashishini afuna ukuphucula ukhuseleko, ukuphucula ulawulo lwezinto ezisetyenzisiweyo, kunye nokuphucula ukusebenza kakuhle ngokubanzi, obu buchwephesha abuyonto nje yokulinganisa—sisixa esibalulekileyo esiqhuba ukuthembeka kunye nemveliso kwimisebenzi yemizi-mveliso yanamhlanje.
