Kodi choyezera madzi cha ultrasound chimalumikizana bwanji ndi nsanja?

Kawirikawiri pali njira zingapo zolumikizirachoyezera madzi cha ultrasonicku nsanja motere:

Kulumikiza kwa Waya:

Kulumikizana kwa RS - 485:

Iyi ndi njira yodziwika bwino yolumikizirana ndi waya. Choyezera madzi cha ultrasonic chili ndi mawonekedwe a RS - 485. Mawonekedwe a RS - 485 a choyezera madzi amalumikizidwa ndi a chosonkhanitsa deta kapena chosungira deta kudzera pa chingwe chopindika. Mukalumikiza, onetsetsani kuti mawayawo ndi olondola, ndipo mizere ya A ndi B imalumikizidwa molingana. Kenako, ikani magawo olumikizirana ofanana pa chosonkhanitsa kapena chosungira, monga baud rate, data bits, stop bits, ndi parity bits, kuti zigwirizane ndi za choyezera madzi kuti zitheke kutumiza deta mokhazikika. Wosonkhanitsa deta kapena chosungira deta amayika detayo papulatifomu kudzera m'njira zina za netiweki.

M - Kulumikizana kwa Ma BUS:

Mamita ena amadzi opangidwa ndi ma ultrasound amagwiritsa ntchito mawonekedwe a M-BUS. Mamita ambiri amadzi amalumikizidwa pogwiritsa ntchito basi ya M-BUS, ndipo mbali imodzi ya basi imalumikizidwa ndi chosonkhanitsa kapena chowongolera cha M-BUS. Chosonkhanitsa kapena chowongolera chimakonza ndikuyika deta ya mita yamadzi yosonkhanitsidwa kenako nkuyitumiza ku nsanja kudzera pa netiweki. Basi ya M-BUS ili ndi ubwino wosavuta kugwiritsa ntchito mawaya komanso mphamvu yolimbana ndi kusokoneza, zomwe zimapangitsa kuti ikhale yoyenera pazochitika zomwe mita yamadzi imakhala yochuluka kwambiri.

Kulumikiza Opanda Zingwe:

NB - Kulumikizana kwa IoT:

Choyezera madzi cha ultrasonic chili ndi gawo lolumikizirana la NB-IoT lomangidwa mkati ndipo limatumiza deta kudzera mu netiweki ya NB-IoT ya woyendetsa. Pambuyo poti choyezera madzi chayikidwa, chiyenera kulembetsedwa ndikukonzedwa pa netiweki, ndipo chidziwitso choyenera cha choyezera madzi chimalumikizidwa ku nsanja. Pambuyo pokonza, choyezera madzi chimatumiza deta ku siteshoni ya woyendetsa kudzera mu module ya NB-IoT malinga ndi kayendedwe kake kapena ngati pali kufunika kolemba deta, kenako siteshoni yapansi imatumiza deta ku nsanja. NB-IoT ili ndi mawonekedwe a kufalikira kwakukulu, kugwiritsa ntchito mphamvu zochepa, komanso kulumikizana kokhazikika, zomwe zimapangitsa kuti ikhale yoyenera kuwerenga mita yakutali komanso kulumikizana kwakukulu kwa mita yamadzi.

Kulumikizana kwa LoRaWAN:

Pa mita yamadzi yopangidwa ndi ultrasonic pogwiritsa ntchito ukadaulo wa LoRaWAN, amalumikizana ndi zipata za LoRa zapafupi kudzera mu ma module opanda zingwe a LoRa. Ulalo wopanda zingwe umakhazikitsidwa pakati pa mita yamadzi ndi chipata kuti itumize deta ku chipata. Chipata chikasonkhanitsa deta ya mita yamadzi angapo, chimayika detayo papulatifomu kudzera mu Ethernet kapena njira zina za netiweki. LoRaWAN imagwiritsidwa ntchito kwambiri pazochitika zina zomwe zimafunikira kwambiri pakutalikirana kwa kulumikizana ndi kugwiritsa ntchito mphamvu, monga machitidwe operekera madzi m'madera akumidzi kapena akutali.

Kulumikizana kwa GPRS/4G:

Pazochitika zina zomwe zimafunikira nthawi yeniyeni komanso kuchuluka kwa deta yotumizira deta, ma ultrasound water meter angagwiritse ntchito ma module olumikizirana a GPRS kapena 4G. Chida choyezera madzi chimakhazikitsa kulumikizana ndi nsanja kudzera mu netiweki ya GPRS kapena 4G ndikuyika deta yosonkhanitsidwa pa nsanjayo nthawi yeniyeni. Ubwino wa njira iyi ndi liwiro lotumizira mwachangu komanso kukhazikika bwino, koma kugwiritsa ntchito mphamvu kumakhala kwakukulu, komwe ndikoyenera kukhazikitsa ma water meter okhala ndi magetsi.

Kulumikizana kwa Bluetooth:

Mu nthawi yochepa, choyezera madzi cha ultrasonic chikhoza kulumikizidwa ku ma terminal anzeru (monga mafoni ndi mapiritsi) kudzera pa Bluetooth. Ikani pulogalamu yofanana pa terminal yanzeru, fufuzani ndikulumikiza ndi choyezera madzi kudzera pa Bluetooth, kenako deta ya meter yamadzi ikhoza kuwerengedwa. Ngati deta ikufunika kukwezedwa pa nsanja, pulogalamuyi imatha kutumiza detayo ku nsanja pamene terminal yanzeru yalumikizidwa ku netiweki. Njirayi nthawi zambiri imagwiritsidwa ntchito pokonza zolakwika pa tsamba, kuwerenga mita, kapena kusonkhanitsa deta kwakanthawi.
