Njengezixhobo zokulinganisa ezikrelekrele, iimitha zamanzi ze-ultrasonic zixhomekeke kwimisebenzi yonxibelelwano ukuze kufezekiswe ukuhanjiswa kwedatha, ukujonga kude, kunye nolawulo. Iindlela zonxibelelwano eziqhelekileyo zahlulwe ngonxibelelwano olunentambo kunye nonxibelelwano olungenazingcingo, ngolu hlobo lulandelayo:
I. Iindlela zoNxibelelwano oluDityanisiweyo
Unxibelelwano olusebenzisa intambo ludlulisela idatha ngemigca ebonakalayo, lunezinzo eziphezulu kunye nobuchule obuqinileyo bokulwa nokuphazamiseka, lufanelekile kwiindawo ezizinzileyo apho ukufakelwa kwentambo kulula khona.
- Unxibelelwano lwe-RS485
- Yenye yezona ndlela zonxibelelwano olunentambo ezisetyenziswa kakhulu kwiinkalo zoshishino. Isebenzisa uthumelo lwesignali eyahlukileyo, enomgama wothumelo ofikelela kwiimitha ezili-1200 kwaye ixhasa uthungelwano lwamanqaku amaninzi (kunokuqhagamshelwa izixhobo ezingama-32).
- Iimitha zamanzi ze-Ultrasonic ziqhagamshela kwii-concentrators, ii-PLC, okanye iikhompyutha eziphezulu ngokusebenzisa ii-interfaces ze-RS485 ukuze kufezekiswe ukulayisha idatha ngexesha langempela (njengokuhamba ngokukhawuleza, ukuhamba okuqokelelweyo) kunye noqwalaselo lweeparameter (ezifana nobubanzi, umda we-alamu).
- Iprotokholi yonxibelelwano isebenzisa kakhulu iModbus-RTU, enokuguquguquka okukhulu kwaye kulula ukuyisebenzisa kwiinkqubo ezahlukeneyo zolawulo.
- Ibhasi ye-M (iBhasi yeMitha)
- Umgangatho webhasi owenzelwe ngokukodwa izixhobo zokulinganisa, oxhasa umbane webhasi (akukho mfuneko yokubonelela ngombane kwiimitha zamanzi ngokwahlukeneyo), ofanelekileyo ukufundwa kweemitha zamanzi, iimitha zobushushu kunye nezinye izixhobo kwindawo enye.
- Umgama wothumelo ungafikelela kwiimitha ezingaphezu kwama-500, kwaye amandla ayo okulwa nokuphazamiseka angcono kune-RS485. Ngocingo olulula (inkqubo yeengcingo ezimbini), isetyenziswa kakhulu kulawulo oluphakathi lweemitha zamanzi kwiindawo zokuhlala nakwizakhiwo.
- Isiphumo sePulse
- Yeyonxibelelwano olulula olusebenzisa intambo. Imitha yamanzi ikhupha imiqondiso yepulse ngokusebenzisa ii-reed switches okanye ii-photoelectric sensors, kwaye inani leepulse lihambelana nokusetyenziswa kwamanzi.
- Ihlala isetyenziselwa ukuqhagamshela nee-PLC, abaqokeleli bedatha kunye nezinye izixhobo ukwenza imitha elula yokuqokelelana kokuhamba kwamanzi. Ixabisa kancinci kodwa inomsebenzi omnye (ikwazi ukudlulisa idatha yokusetyenziswa kuphela).
II. Iindlela zoNxibelelwano olungenazingcingo
Unxibelelwano olungenazingcingo aludingi zintambo, lunokuguquguquka okuphezulu, kwaye lufanelekile kwiindawo ezithe saa kunye neemeko apho ukufakelwa kwezintambo kunzima khona (njengeendawo zasemaphandleni, ukwakhiwa ngokutsha koluntu lwakudala).
- I-LoRa (iRadio ende)
- Ngokusekelwe kubuchwepheshe be-spread spectrum, inomgama omde wokudlulisela (iikhilomitha ezi-1-3 kwiindawo zasezidolophini, iikhilomitha ezi-5-10 kwiindawo ezikufutshane), ukusetyenziswa kwamandla okuphantsi (ubomi bebhetri bunokuba yiminyaka emi-5-10), kwaye ixhasa uthungelwano olukhulu (ngaphezulu kwezixhobo ezili-1,000).
- Ifanelekile ukufundwa kweemitha zamanzi kude, ingakumbi xa isetyenziswa kakhulu kwiimeko zokugubungela indawo ebanzi (ezifana neenethiwekhi zemibhobho zasezidolophini, iinkqubo zokubonelela ngamanzi zasemaphandleni). Inganxibelelana ngokuthe ngqo neesango zeLoRa, ize ifikelele kwiqonga lelifu ngesango.
- I-NB-IoT (i-intanethi yezinto zeNarrow Band)
- Itekhnoloji yenethiwekhi yendawo ebanzi enamandla aphantsi esekelwe kwiinethiwekhi zeselula, ezigutyungelwe zizikhululo zesiseko ezibonelelwa ngabaqhubi, ngaphandle kwesidingo sokwakha amasango ngokwakho. Inothumelo oluzinzileyo kunye nogutyungelwe olubanzi kakhulu (ingangena eludongeni nakwimibhobho engaphantsi komhlaba).
- Ixhasa uqhagamshelo olukhulu (iseli nganye inokudibanisa izixhobo ezili-100,000) kunye nokusetyenziswa kwamandla okuphantsi (ubomi bebhetri yiminyaka emi-3-8), ifanelekile kwiindlela ezinkulu zokuguqula iimitha zamanzi ezidolophini, ukufikelela ngqo kwiqonga lelifu ukuze kufezekiswe ukujonga okukude kunye nohlalutyo lwedatha.
- ibluetooth
- Unxibelelwano olungenazingcingo oluhamba umgama omfutshane (ngesiqhelo luziimitha ezili-10-100) olusebenzisa amandla aphantsi, olusetyenziswa kakhulu ekulungiseni iingxaki kwindawo kunye nokufunda idatha umgama omfutshane (njengokuba abafundi beemitha besondela kwiimitha zamanzi besebenzisa izixhobo eziphathwayo ukuze bafunde idatha).
- Ayifanelekanga ukufundwa kwemitha ekude, kodwa ingasetyenziswa njengendlela yonxibelelwano encedisayo ukuze kube lula kubasebenzi bokulungisa ukuseta iiparameter okanye ukusombulula iingxaki kwindawo.
- I-GPRS/4G (Inethiwekhi yeSelfowuni)
- Ngokusekelwe kwinethiwekhi yomqhubi weselula, inesantya esiphezulu sokudlulisa idatha kwaye inokudlulisa idatha eninzi ngexesha langempela, kodwa ukusetyenziswa kwayo kwamandla kuphezulu (ifuna umbane wangaphandle okanye ibhetri enamandla amakhulu), kwaye ixabiso liphezulu kakhulu.
- Ifanelekile kwiimeko ezineemfuno eziphezulu zokusebenza kwedatha ngexesha langempela (njengokubeka esweni iimitha zamanzi zoshishino ezinobukhulu obukhulu) okanye njengendlela yokunxibelelana yogcino kwezinye iindlela ezingenazingcingo.
Ukukhethwa kwendlela yonxibelelwano yeemitha zamanzi ze-ultrasonic kufuneka kumiselwe ngokupheleleyo ngokwemeko yesicelo (efana nolawulo oluphakathi/uyilo olusasazekileyo, idolophu/ilali), umgama wokudluliselwa, iimfuno zokusetyenziswa kombane, kunye nohlahlo lwabiwo-mali lweendleko:
- Unxibelelwano olusebenzisa intambo (RS485, M-Bus) lufanelekile kwiifektri ezizinzileyo neziphakathi, kugxilwe kakhulu kuzinzo;
- Unxibelelwano olungenazingcingo (iLoRa, iNB-IoT) lufanelekile kwiimeko ezisasazekileyo nezinkulu, kugxilwe kakhulu ekuguquguqukeni;
- I-pulse output kunye ne-Bluetooth zisetyenziswa kakhulu kwi-metering elula okanye kwi-assistant debugging.
Kwiindlela ezisebenzayo, ezinye iimitha zamanzi ze-ultrasonic ziya kudibanisa iindlela ezininzi zonxibelelwano (ezifana ne-“RS485 + LoRa”) ukuze zilungelelanise iimeko zokusetyenziswa ezintsonkothileyo.
