Njengoko izakhiwo, iifektri, kunye neziseko zamandla zisiya zisiba zedijithali ngakumbi, imibutho ifuna iindlela ezikrelekrele zokujonga ukusetyenziswa kombane kwiindawo ezahlukeneyo nakwiinkqubo.

Iimitha zamandla zemveli zibonelela kuphela ngezibalo zasekuhlaleni. Iinkqubo zamandla zanamhlanje zifunaukufikelela kwedatha ngexesha langempela, ukuhlanganiswa kweqonga, kunye nokubeka esweni okunokwandiswa kuzo zonke iiasethi ezisasaziweyo.

Yiyo loo ntoIimitha zamandla ezikrelekrele ezine-MQTT APIngokukhawuleza ziba yinxalenye ebalulekileyo yoyilo lwanamhlanje lokujonga amandla.

Imitha yamandla ehlakaniphile enikwe amandla yi-MQTT ivumela idatha yamandla ukuba idluliselwe ngexesha langempela ukuzeIiNkqubo zoLawulo lwaMandla (i-EMS), iiNkqubo zoLawulo lweZakhiwo (i-BMS), kunye namaqonga e-IoT enziwe ngokwezifisoEndaweni yokusebenza njengesixhobo sokulinganisa esizimeleyo, imitha iba yinxalenye yenkqubo yamandla edibeneyo apho idatha yombane inokuhlalutywa, ibonwe, kwaye isetyenziswe ukuphucula imisebenzi.

At Ubuchwepheshe be-OWON, siyila kwaye senza iimitha zamandla ezikrelekrele ngokukodwa kwiimeko zokudibanisa. Izixhobo zethu zidibanisa izixhobo zokulinganisa ezichanekileyo kunyevula ii-API ze-MQTT, okuvumela abadibanisi beenkqubo kunye nababoneleli ngezisombululo zamandla ukuba baqhagamshele idatha yombane ngqo kumaqonga abo esoftware.

Yintoni iSmart Energy Meter ene-MQTT API?

A Imitha yamandla ehlakaniphile ene-MQTT APIyimitha yombane enikwe amandla yi-IoT ethumela idatha yamandla ngexesha langempela ngeprotocol ye-MQTT.

I-MQTT (i-Message Queuing Telemetry Transport) isetyenziswa kakhulu kwiinkqubo ze-IoT kuba ibonelela:

Unxibelelwano olulula
Ukuhanjiswa kwedatha okuthembekileyo ngexesha langempela
Uqhagamshelo lwesixhobo esikwaziyo ukwandiswa
Ukuhlanganiswa kwelifu okusebenzayo

Xa idityaniswe kwinkqubo yokubeka esweni, imitha yamandla ye-MQTT inokupapasha idatha yombane rhoqo efana nale:

I-Voltage
Okwangoku
Amandla asebenzayo
Into yamandla
Izihlandlo
Ukusetyenziswa kwamandla

Olu lwazi lunokusetyenziswa zizicelo ezininzi ngaxeshanye, kubandakanya:

Iideshibhodi zamandla
Iinkqubo zokubeka esweni kwemizi-mveliso
Amaqonga okwakha akrelekrele
Iinjini zohlalutyo lwelifu

Isiphumo si-inkqubo yokujonga amandla edijithali ngexesha langempelaexhasa izigqibo zokusebenza kunye nokuphuculwa kwamandla.

Kutheni iiMeter zamandla zeMQTT zilungele ukuhlanganiswa kwe-EMS kunye ne-BMS

Amaqonga olawulo lwamandla axhomekeke kulwazi oluhambelanayo noluthembekileyo oluvela kwizixhobo zasentsimini.

Izisombululo zemveli zokulinganisa zihlala zixhomekeke kwiiprotokholi ezizimeleyo ekunzima ukuzidibanisa noyilo lwamafu lwanamhlanje.

Iimitha zamandla ze-MQTT zisombulula le ngxaki ngokubonelelaunxibelelwano olusemgangathweni, oluqhutywa ziziganeko.

Oku kuvumela abaphuhlisi beenkqubo ukuba badibanise iimitha ngokulula ku:

Iinkqubo zoLawulo lwaMandla (i-EMS)
Iinkqubo zoLawulo lweZakhiwo (i-BMS)
Amaqonga okubeka esweni e-SCADA
Iiplatifomu zelifu ze-IoT
Isoftware yokwenza izinto ngokuzenzekelayo kwimizi-mveliso

Ngenxa yokuba i-MQTT isebenzisa uyilo lokushicilela-ukubhalisa, iinkqubo ezininzi zinokufumana idatha yamandla efanayo ngaxeshanye ngaphandle koqwalaselo olongezelelweyo lwesixhobo.

Oku kwenza i-MQTT ifaneleke ngakumbi kwi-ukuthunyelwa okukhulu kwizakhiwo zorhwebo, iifektri, kunye neeprojekthi zeziseko zophuhliso zamandla.

Uyilo oluqhelekileyo lweNkqubo yokuJonga amandla ye-MQTT

Kwinkqubo yanamhlanje yokujonga amandla e-IoT, iimitha ezikrelekrele zisebenza njengezixhobo ezisemaphethelweni eziqokelela idatha yombane kwaye ziyithumele kwiqonga eliphakathi.

Uyilo oluqhelekileyo lubukeka ngolu hlobo:

Imitha yamandla ehlakaniphile
→ Isango okanye iRouter
→ Umthengisi we-MQTT
→ Iqonga le-EMS / BMS / IoT

Kule ndlela yokwakha:

Imitha ekrelekrele ilinganisa iiparameter zombane ngexesha langempela.
Idatha idluliselwa ngeWiFi, iZigbee, okanye ezinye iinethiwekhi zonxibelelwano.
Umthengisi we-MQTT usasaza idatha kwiinkqubo ezibhalisiweyo.
Ukubeka esweni iinkqubo zesoftware kunye nokubonisa ulwazi.

Uyilo lweqonga le-OWON le-IoT luvumela abahlanganisi beenkqubo ukuba baqhagamshele izixhobo besebenzisaii-API zenqanaba lesixhobo, ukuhlanganiswa kwesango, okanye unxibelelwano oluvela kwilifu ukuya kwilifu, ebonelela ngeendlela zokudibanisa eziguquguqukayo kumaqonga eqela lesithathu.
