Mu ntchito zamafakitale—kuyambira ku malo oyeretsera mafuta osakaniza mpaka malo osungira tirigu omwe amayang'anira malo osungira tirigu, ndi mafakitale amadzi otayira omwe amayang'anira matanki a matope—kuyeza molondola kwa mulingo ndikofunikira kwambiri. Kumaonetsetsa kuti malo osungiramo zinthu ndi otetezeka, kumawongolera kasamalidwe ka zinthu, kumaletsa kusefukira kwa madzi kapena kuuma, komanso kumathandizira njira zopangira zinthu mosasunthika. Komabe, zida zoyezera mulingo monga masensa a ultrasound, ma switch oyandama, kapena ma transmitter okakamiza nthawi zambiri amavutika m'malo ovuta kapena ovuta: zizindikiro za ultrasonic zimatsekedwa ndi fumbi kapena nthunzi, ma float amamatira m'madzi okhuthala, ndipo ma transmitter okakamiza amalephera m'matanki okhala ndi kutentha kosiyanasiyana kapena zinthu zowononga. Lowani mu transmitter ya radar yosagwirizana—njira yosinthira masewera yomwe imapereka kulondola kosayerekezeka kwa muyeso wa thanki ndi mulingo wa silo, ngakhale m'mikhalidwe yovuta kwambiri.
Pakati pake, chotumizira cha radar chomwe sichimakhudzana ndi kukhudzana chimagwira ntchito motsatira mfundo ya nthawi yowuluka (ToF). Chimatulutsa ma radar pulses okwera kwambiri (nthawi zambiri 24GHz kapena 80GHz) kuchokera ku antenna yomwe ili pamwamba pa thanki kapena silo. Ma pulses awa amayenda pansi, amawonetsa pamwamba pa madzi, olimba, kapena matope mkati, ndikubwerera ku chotumizira. Chipangizochi chimawerengera nthawi yomwe ma pulses amatenga kuti apite pamwamba ndikubwerera, kenako chimagwiritsa ntchito deta iyi (pamodzi ndi liwiro la mafunde a radar) kuti chiwerengere mtunda weniweni kuchokera ku chinthucho—kumene chimachokera mulingo wapano. Mosiyana ndi zida zogwiritsa ntchito kukhudzana, sichikhudza njira yoyezera, kuchotsa chiopsezo cha kuwonongeka, kuipitsidwa, kapena kulephera kwa makina.
Chomwe chimasiyanitsa ukadaulo uwu ndi kulondola kwake kwapadera, chofunikira kwambiri pakugwiritsa ntchito thanki ndi silo komwe ngakhale zolakwika zazing'ono zoyezera zingayambitse zotsatira zokwera mtengo. Ma transmitter ambiri osakhudzana ndi radar level amadzitamandira kulondola kwa ±1mm mpaka ±5mm, kutengera mtundu ndi mulingo woyezera (womwe ungatalikire kuyambira mamita 0.3 mpaka mamita 80). Kulondola kumeneku kumagwira ntchito ngakhale m'zochitika zosinthika: mwachitsanzo, m'matanki amafuta okhala ndi malo ogwedezeka kapena masilo okhala ndi zinthu zozungulira monga simenti kapena ma pellets apulasitiki. Zinthu zapamwamba monga kusefa ma echo ndi ma algorithms opangira ma signal zimawonjezera kulondola ponyalanyaza zowunikira zabodza kuchokera ku makoma a thanki, zomangamanga zamkati (monga ma agitators kapena ma baffles), kapena mitambo yafumbi - mavuto wamba omwe amakhudza zida zina zoyezera.
Ubwino wina wa ma radar transmitter osakhudzana ndi kusinthasintha kwawo m'malo osungiramo zinthu ndi malo osungiramo zinthu. Amagwira ntchito zosiyanasiyana: zakumwa (kuphatikizapo ma hydrocarbon, mankhwala, ndi madzi), zinthu zolimba (tirigu, ufa, ndi ma pellets), komanso zinthu zovuta kuyeza (monga matope a m'madzi otayira kapena malo osungiramo zinthu). Kapangidwe kawo kolimba kamapirira nyengo zovuta kwambiri: kutentha kwambiri (mpaka 200°C kapena kuposerapo ndi mitundu yapadera), kupsinjika kwakukulu (mpaka 100 bar), ndi mlengalenga wowononga - zomwe zimapangitsa kuti zikhale zabwino kwambiri m'mafakitale monga petrochemicals, chakudya ndi zakumwa, ndi migodi. Mitundu yambiri imabweranso ndi IP67 kapena IP68 yoteteza, kuonetsetsa kuti fumbi, madzi, ndi chinyezi sizingagwire ntchito, zomwe ndizofunikira kwambiri pa malo osungiramo zinthu akunja kapena malo osungiramo zinthu zonyowa.
Kwa ogwira ntchito m'mafakitale, ubwino wake umapitirira kulondola ndi kulimba mpaka pakugwira bwino ntchito. Ma transmitter a radar osakhudzana nawo amafunika kusamalidwa pang'ono: popanda kusuntha ziwalo kapena kukhudzana ndi sing'anga, palibe chifukwa choyeretsa nthawi zonse, kuwerengera, kapena kusintha magawo—mosiyana ndi ma switch oyandama omwe amafunikira kukonzedwa pafupipafupi kapena ma transmitter opanikizika omwe amatha kutsekeka. Amalumikizananso bwino ndi machitidwe owongolera omwe alipo kudzera mu ma protocol wamba monga Modbus, HART, kapena 4-20mA analog output. Izi zikutanthauza kuti deta yamlingo imatha kutumizidwa nthawi yeniyeni ku machitidwe a SCADA, mapulogalamu oyang'anira zinthu, kapena nsanja zochokera kumtambo, zomwe zimathandiza ogwira ntchito kuyang'anira milingo patali, kukhazikitsa machenjezo odziyimira pawokha a milingo yotsika/yapamwamba, ndikupanga zisankho zozikidwa pa data zokhudza kudzazanso kapena kutulutsa matanki/malo osungiramo zinthu.
Taganizirani za chikepe chachikulu cha tirigu chokhala ndi malo ambiri osungira tirigu ndi chimanga. Chotumizira radar chomwe sichimalumikizana ndi munthu chomwe chimayikidwa pa malo aliwonse osungiramo zinthu chimapereka deta yolondola komanso yeniyeni, zomwe zimathandiza kuti malowo azitsatira zinthu popanda kuyang'aniridwa ndi manja (zomwe zimawononga nthawi komanso zoopsa). Ngati malo osungiramo zinthu ayandikira kuchuluka kwa mafuta, makinawo amachititsa chenjezo kuti asiye kudzaza mafuta, zomwe zimaletsa kusefukira kwa mafuta. Mu malo oyeretsera mafuta, ma radar transmitters omwe ali m'matanki amafuta osakonzedwa amaonetsetsa kuti mafuta osungidwa akuyezedwa molondola, kuthandizira kutsatira zofunikira pa malipoti ndikuwongolera nthawi yotumizira mafuta m'matanki.
Pomaliza, chotumizira cha radar chosakhudzana ndi kukhudzana chasinthanso muyeso wa thanki ndi silo. Kapangidwe kake kosakhudzana ndi kukhudzana kamachepetsa zolakwika za zida zachikhalidwe, kulondola kwake kwambiri kumachepetsa zoopsa zogwirira ntchito, ndipo kusinthasintha kwake kumagwirizana ndi zosowa zosiyanasiyana zamafakitale. Kwa mabizinesi omwe akufuna kupititsa patsogolo chitetezo, kukonza kasamalidwe ka zinthu, ndikuwonjezera magwiridwe antchito onse, ukadaulo uwu si chida chongoyezera chabe - ndi chuma chofunikira chomwe chimalimbikitsa kudalirika ndi kupanga bwino ntchito zamafakitale amakono.
