Ma ultrasound water mita amagwiritsa ntchito ukadaulo wa ultrasound wosiyana ndi nthawi kuti ayesere kuchuluka kwa madzi popanda kusuntha ziwalo zamkati. Ali ndi ma interface osiyanasiyana otulutsa ma signal, amathandizira kuwerenga kwanuko, kutumiza kwakutali ndi waya komanso kukweza deta ya IoT yopanda zingwe, zomwe zimathandiza kwambiri kasamalidwe ka madzi anzeru, kuyang'anira mafakitale ndi kuthirira ulimi. Mitundu yonse yotulutsa imatha kugawidwa m'magulu otulutsa mpweya, mawonekedwe a infrared optical, kulumikizana kwa mabasi ndi waya komanso kutumiza kwa IoT opanda zingwe.
Kutulutsa kwa Pulse
Kutulutsa kwa pulse ndi njira yosavuta kwambiri yotumizira chizindikiro. Chida choyezera madzi chimasintha kuchuluka kwa madzi kokhazikika kukhala chizindikiro cha pulse, ndipo zida zina kapena ma PLC amawerengera kuchuluka kwa madzi omwe amagwiritsidwa ntchito powerengera manambala a pulse. Chimagwiritsa ntchito kapangidwe ka optocoupler kopanda mphamvu kwambiri, kogwirizana ndi ma ultrasound mita oyendetsedwa ndi batri. Njira yotsika mtengo iyi imagwiritsidwa ntchito kwambiri m'mafakitale ang'onoang'ono oyang'anira ndi makina osavuta oyezera madzi. Komabe, chimangotumiza madzi ochulukirapo popanda chidziwitso cha nthawi yeniyeni cha flow rate, kutentha kapena alamu yolakwika, zomwe zimapangitsa kuti chisagwiritsidwe ntchito bwino ndi akatswiri.
Chiyankhulo cha Kuwala cha Infrared
Doko la kuwala la infrared limagwira ntchito ngati njira yowerengera yapafupi ndi munda yomwe ikutsatira miyezo ya EN13757. Akatswiri amagwiritsa ntchito ma infrared reader ogwiritsira ntchito m'manja kuti asonkhanitse deta pamalopo popanda kutsegula nyumba ya mita. Kupatula kuwerenga kuchuluka kwa kayendedwe ka madzi, kuyenda kwa madzi nthawi yomweyo ndi magetsi a batri, mawonekedwe ake amathandizira kuwerengera kwa mita, kukonza magawo ndi kuzindikira zolakwika. Amagwiritsidwa ntchito makamaka poyang'ana ndi manja nthawi zonse komanso kukonza zida m'madera okhala anthu, osafuna mawaya ndipo ali ndi kulumikizana kosavuta pakati pa munthu ndi munthu patali.
Kutulutsa Basi Yolumikizidwa ndi Waya
Mayankho awiri akuluakulu a mabasi olumikizidwa ndi waya ndi RS485 ndi M-Bus, onse amathandizira kuwerenga kwakutali kwa malo ambiri. RS485 imagwira ntchito ndi protocol ya Modbus RTU, kupereka zizindikiro zokhazikika mpaka mamita 1,200. Imatha kutumiza deta yonse kuphatikiza kuyenda kwa mbali ziwiri, kutentha kwapakati, kulephera kwa batri yotsika komanso masensa, imagwirizana ndi makina a PLC ndi SCADA a mapaipi amadzi a fakitale. M-Bus (Meter Bus) ndi muyezo waku Europe wodzipereka ku mita yogwiritsira ntchito, womwe umakwaniritsa magetsi ndi kutumiza deta kudzera pa zingwe ziwiri zazikulu. Ndi yabwino kwambiri pamamita amadzi okhala okhala okhala ndi anthu ambiri, omwe amagwiritsidwa ntchito kwambiri m'mapulojekiti anzeru okhala ku Europe ndi m'nyumba kuti awerengere mita yakutali.
Zotulutsa Zopanda Waya za IoT
Ma module opanda zingwe amachotsa kumangidwa kwa mawaya, chisankho chodziwika kwambiri pa ma network amakono anzeru amadzi. NB-IoT imagwiritsa ntchito malo oyambira ma cellular okhala ndi ma signal amphamvu olowera m'zitsime zapansi panthaka ndi pansi panthaka. Meter imayika deta yokha ku ma platform amtambo nthawi yokonzedweratu ndi kutayika kwa mphamvu kochepa kwambiri, kuonetsetsa kuti batri limakhala ndi moyo kwa zaka zoposa 6. Imakwaniritsa mapaipi ogawa madzi m'mizinda komanso kuyang'anira madzi akumidzi akutali. LoRa ndi LoRaWAN amagwiritsa ntchito ma signal a wailesi akutali, omwe amaphimba makilomita 3-10 pansi pa chipata. Oyenera mapaki amakampani okhazikika komanso madera akuluakulu othirira, amagwiritsa ntchito ma network opanda zingwe m'madera osiyanasiyana popanda kudalira ma network a ma cellular. M-Bus yopanda zingwe ndi njira ina ya RF yowerengera mita yoyenda kapena yoyendetsa, yomwe imagwiritsidwa ntchito kwambiri poyang'anira madzi akumatauni aku Europe.
Buku Lotsogolera Kusankha Ntchito
Ogwiritsa ntchito amasankha zotulutsa malinga ndi momwe zimakhalira. Nyumba zogona zapakati zimakonda kuwerenga kwa waya kwa M-Bus; mapaipi akunja omwazikana amasankha NB-IoT; malo ochitira ntchito zamafakitale amagwiritsa ntchito RS485 kuti agwirizane ndi makina odziyimira okha; kuyang'anira malo kumagwiritsa ntchito ma infrared interfaces, ndipo zida zosavuta zoyezera zimagwiritsa ntchito mphamvu ya pulse output. Ndi kufananiza kosinthasintha kwa njira zingapo zotulutsira, mita yamadzi ya ultrasonic imakwaniritsa zofunikira zonse kuyambira kuwerenga kwa patrol pamanja mpaka kasamalidwe ka madzi anzeru a IoT.
