Mu gawo lachikhalidwe la kuyang'anira madzi, timagwiritsa ntchito zida zakuthupi monga ma dipstick, ma ruler, kapena ma bobber oyandama. Komabe, mafakitale amakono asintha njira yosavuta iyi yoyezera kukhala sayansi yolondola kwambiri. Ndi kusintha kwa ukadaulo wa Non-Contact Flow Meter—makamaka kugwiritsa ntchito ukadaulo wa 76-81 GHz FMCW (Frequency-Modulated Continuous Wave)—kasamalidwe ka madzi kakusintha kuchoka pa "kuyerekeza kolakwika" kupita ku "kulamulira kolondola".
Kutengera ndi deta yaposachedwa yaukadaulo, nkhaniyi ikufotokoza momwe sensa yapamwamba iyi ikusinthira miyezo ya ukadaulo wa Radar Flow Meter ndikusanthula kufunika kwake kofunikira mu ntchito monga River Flow Monitoring ndi Sewer Flow Meter / Wastewater Flow Monitoring.
1. Kudumphadumpha kwaukadaulo: Kupita patsogolo ku Era ya 80GHz
Ngakhale kuti ukadaulo wonse wa 24GHz/80GHz Radar Flow Meter ulipo pamsika, sensa ya 76-81 GHz yapamwamba yomwe yafotokozedwa mu gwero lake ikuyimira kulondola kwakukulu,. Mosiyana ndi ma radar osavuta a pulse, sensa iyi imagwiritsa ntchito ukadaulo wa FMCW kutulutsa "kulira" kosalekeza kwa mafunde a wailesi, zomwe zimathandiza kuti miyeso ikhale yodalirika kwambiri.
Ubwino wake waukulu uli pakupeza "kulondola kosatheka":
• Kulondola Kwambiri kwa Ma Range ndi Millimeter: Imatha kuyeza kuchuluka kwa madzi kuchokera pa mtunda wa mamita 65 ndi kulondola kwa ±1mm. Kuti timvetse bwino izi, zili ngati kuyeza makulidwe a khadi la ngongole kudutsa dziwe lalikulu losambira.
• Yankho Lachangu: Limapereka deta yopitilira, limatenga muyeso watsopano ma milliseconds 500 mpaka 800 aliwonse.
• Malo Osawoneka Bwino: Kapangidwe kapamwamba kamalola kuti izindikire molondola ngakhale madzi atakhala okwera kwambiri komanso pafupi ndi sensa, zomwe zimapangitsa kuti pasakhale kufunikira koyang'anira zoopsa pakamwa panthawi ya kusefukira kwa madzi.
2. Kuyang'ana Kwambiri ndi Luntha: Mayankho a Open Channel Flow Meter a Malo Ovuta
Mu Open Channel Flow Meter, chilengedwe nthawi zambiri chimakhala chosokonekera. Zizindikiro zomwe zimagunda m'mphepete mwa mitsinje kapena makoma a ngalande zimatha kusokoneza deta. Sensor iyi imathetsa vutoli ndi radar beam yolunjika kwambiri yokhala ndi ngodya yopapatiza ya 6° beam, yomwe imagwira ntchito ngati laser kuti ifike pamwamba pa madzi.
• Chitetezo Chosokoneza: Malangizo okhazikitsa amalimbikitsa kuyika sensa osachepera 30cm kuchokera pakhoma kuti muwonetsetse kuti mphamvu ikulunjika pamadzi okha.
• False Echo Learning: Ili ndi luso la "False echo learning" lomwe lingakonzedwe kuti lisamaganizire zopinga zokhazikika zomwe zimawonekera. Izi ndizofunikira kwambiri pa Muyeso wa Madzi Amvula, komwe mapaipi otulutsira madzi kapena ngalande nthawi zambiri zimakhala ndi zinyalala kapena zinthu zosakhazikika; kusefa mwanzeru kumaonetsetsa kuti makina odziyimira okha sayambitsidwa ndi ma alarm abodza.
3. Kulumikizana kwa Bluetooth: Kusintha Ntchito Zowunikira Mayendedwe a Mtsinje
Pochita Kuwunika kwa Mtsinje kuthengo, zida zachikhalidwe nthawi zambiri zimafuna akatswiri kuti akwere makwerero kapena kunyamula ma laputopu akuluakulu kuti alumikize zingwe. Sensa yapamwamba iyi imayambitsa kuphweka kwa zida zamagetsi zamagetsi pogwiritsa ntchito ukadaulo wa Bluetooth 5.0 womangidwa mkati.
Ogwira ntchito yokonza zinthu amatha kugwiritsa ntchito pulogalamu ya foni yam'manja yotchedwa "Radar Tools" (yomwe ikupezeka pa iOS ndi Android) kuti alumikizane ndi chipangizocho popanda waya kuchokera pa mtunda wa mamita 12. Izi zimapangitsa kuti ntchito yowopsa ya anthu awiri ikhale yogwira ntchito yofulumira komanso yotetezeka yochitidwa ndi munthu m'modzi kuchokera pansi.
4. Kulimba Kolimba: Kuthana ndi Vuto la Chitsulo Choyezera Kuyenda kwa Madzi Otayira/Kuyang'anira Kuyenda kwa Madzi Otayira
Chida Choyezera Kuyenda kwa Madzi Otayira/Kuwunika Kuyenda kwa Madzi Otayira ndi chimodzi mwa malo ovuta kwambiri, komwe zipangizo ziyenera kupirira dzimbiri, chinyezi, ndi kukhudzidwa ndi zinthu zakuthupi.
Sensa iyi yapangidwa kuti igwiritsidwe ntchito pazochitika zoopsa kwambiri:
• Chitetezo cha IP68: Chimatsekedwa kwathunthu ku fumbi ndipo chimatha kupulumuka chikamizidwa m'madzi kwa nthawi yayitali, zomwe zimapangitsa kuti chikhale choyenera kwambiri m'madzi otayira madzi omwe angadzazidwe ndi mphepo yamkuntho.
• Kutentha Kwambiri & Zipangizo Zolimba: Imagwira ntchito bwino kuyambira -30°C mpaka 70°C. Chipolopolocho chimapangidwa ndi zipangizo zolimba monga chitsulo chosapanga dzimbiri ndi PP, ndipo pali njira yolimba kwambiri ya aluminiyamu yomwe ingagwiritsidwe ntchito pa chitsanzo cha 4-20mA kuti isawonongeke ndi dzimbiri.
5. Kulumikizana kwa Mafakitale: Gwero Lalikulu la Deta Yodzipangira Yokha
Sensa yodzipatula siingapange makina amakono a Radar Flow Meter. Chipangizochi "chimalankhula" chilankhulo cha makina odziyimira pawokha a mafakitale, chomwe chili ndi mitundu iwiri yayikulu yotulutsa:
1. 4-20mA/HART: Chizindikiro cha analogi chokhazikika chomwe chimawonjezeredwa ndi deta yowunikira ya digito.
2. RS485/MODBUS: Njira yolimba yolumikizirana ndi zida zambiri.
Ma protocol awa amalola kuti igwirizane bwino ndi ma PLC (Programmable Logic Controllers), ndikuisintha kuchoka pa chida chodziyimira payokha kukhala gwero lofunikira la deta yamakompyuta akuluakulu. Kaya kuyambitsa machenjezo a kusefukira kwa madzi kapena kuwongolera kudzaza matanki amafakitale, zimathandiza kuyang'anira molondola popanda kulowererapo kwa anthu ambiri.
Seti yonse ya ma seva ndi mapulogalamu opanda zingwe, imathandizira RS485 GPRS /4g/WIFI/LORA/LORAWAN
Kuti mudziwe zambiri zokhudza sensa ya madzi ya radar zambiri,
