Imitha Yamandla Ehlakaniphile ene-MQTT Yomsizi Wasekhaya kanye Nezinhlelo Zamandla ze-IoT

Isingeniso: Kungani i-MQTT Ibalulekile Ekulinganisweni Kwamandla Kwesimanje

Njengoba izinhlelo zamandla ezihlakaniphile zixhumana kakhulu, ukuqapha kwendabuko kwamafu kuphela akusanele. Amaphrojekthi wamandla ezindawo zokuhlala kanye namabhizinisi amancane namuhla adinga kakhuluukufinyelela kwedatha yendawo, yesikhathi sangempela, kanye nezinga lesistimu—ikakhulukazi uma kuhlanganiswa amamitha kagesi kumapulatifomu afana ne-Home Assistant, izinhlelo zokuphatha amandla zokwakha, noma izakhiwo ze-IoT ezenziwe ngokwezifiso.

Lolu shintsho lubangela ukukhula kwesidingo se-amamitha wamandla ahlakaniphile anokusekelwa kwe-MQTT. Kubahlinzeki bezixazululo kanye nabaklami bezinhlelo, i-MQTT ivumela ukushintshaniswa kwedatha okuqondile, ukuhlanganiswa kwezinhlelo okuguquguqukayo, kanye nokuzimela kwepulatifomu isikhathi eside.

Kusukela kokuhlangenwe nakho kwethu njengomkhiqizi wamamitha kagesi ahlakaniphile, imibuzo efana nokuthi"Ingabe le mitha yamandla iyayisekela i-MQTT?" or "Ngingayihlanganisa kanjani imitha yamandla nomsizi wasekhaya ngisebenzisa i-MQTT?"akusezona izimo zokusetshenziswa ezithuthukisiwe—seziba yizidingo ezijwayelekile kumaphrojekthi wamandla wesimanje.

Iyini i-Smart Energy Meter ene-MQTT?

A imitha yamandla ehlakaniphile ene-MQTTiyimitha kagesi ekwazi ukushicilela idatha yokulinganisa yesikhathi sangempela—njengamandla, amandla, i-voltage, kanye nogesi—ngqo kumthengisi we-MQTT. Esikhundleni sokuthembela kuphela kumadeshibhodi efu azimele, i-MQTT ivumela idatha yamandla ukuthi isetshenziswe izinhlelo eziningi ngasikhathi sinye.

Izinzuzo ezibalulekile zifaka:

Ukutholakala kwedatha yendawo ngaphandle kokuthembela efwini
Ukuxhumana okulula, okubambezeleka kancane
Ukuhlanganiswa okulula namapulatifomu e-Home Assistant, EMS, kanye ne-BMS
Ukuguquguquka kwesikhathi eside kokwandiswa kwesistimu

Yingakho amagama angukhiye afanaUmsizi Wasekhaya wemitha yamandla ye-mqtt, imitha yamandla i-WiFi MQTT, futhiimitha yamandla ehlakaniphile i-MQTTkuvela kakhulu ekusesheni kwesigaba sokuthengwa kwempahla.

Kungani i-MQTT Ikhethwa Ezinhlelweni Zokuqapha Amandla

Uma kuqhathaniswa nama-REST noma ama-API e-cloud kuphela, i-MQTT ifaneleka kakhulu ekuqapheni amandla ngoba isekelaukusakaza idatha okuqhubekayofuthiizakhiwo eziqhutshwa yimicimbi.

Ekusetshenzisweni okusebenzayo, i-MQTT ivumela:

Idatha yamandla yesikhathi sangempela yeziqalisi zokwenza ngokuzenzakalela
Ukuhlanganiswa namasango e-Modbus noma abalawuli bomphetho
Ukugeleza kwedatha okuhlangene kuwo wonke amamitha wamandla, ama-inverter, kanye nezinhlelo zokugcina

Kumaphrojekthi adinga izimpendulo ezithembekile—njengokulawula umthwalo, ukwenza ngcono amandla, noma ukugeleza kwamandla okuphikisana nokubuyela emuva—i-MQTT ivame ukuba ungqimba lokuxhumana oluyisisekelo.

I-MQTT kanye nomsizi wasekhaya: Inhlanganisela yemvelo

Abasebenzisi abaningi abafunaimitha yamandla ye-mqttUmsizi Wasekhayaabafuni izifundo—bahlola ukuthi idivayisi iyafanelana yini nokwakhiwa kwesistimu yabo.

Umsizi Wasekhaya usekela i-MQTT ngokwendabuko, okwenza:

Amadeshibhodi wamandla endawo
Imithetho yokwenza izinto ngokuzenzakalela esuselwe kumandla
Ukuhlanganiswa namashaja elanga, ama-EV, kanye nemithwalo ehlakaniphile

Uma imitha yamandla ehlakaniphile ishicilela izihloko ze-MQTT ezijwayelekile, ingafakwa ku-Home Assistant ngaphandle kokuvalela iphrojekthi ohlelweni olulodwa lomthengisi.

Ukwakhiwa kwe-Smart Energy Meter MQTT: Indlela Esebenza Ngayo

Kusethaphu ejwayelekile:

Imitha yamandla ilinganisa amapharamitha kagesi wesikhathi sangempela isebenzisa ama-CT clamp.
Idatha idluliselwa nge-WiFi noma i-Zigbee esangweni lendawo noma ngqo kunethiwekhi.
Amanani okulinganisa ashicilelwa kumthengisi we-MQTT.
Umsizi Wasekhaya noma ezinye izinhlelo zivumelana nezihloko ezifanele.

Lolu lwakhiwo luvumelaukuqapha amandla okungakhuliswa, okungakhethi umthengisi, okuyinto ethandwa kakhulu ekusetshenzisweni kwamandla ahlakaniphile kochwepheshe.

I-Owon's PC321 Smart Energy Meter enokusekelwa kwe-MQTT

Ukuze kuhlangatshezwane nalezi zimfuneko zokuhlanganiswa,Imitha yamandla ehlakaniphile ye-PC321yakhelwe ukusekela ukulethwa kwedatha yamandla esekwe ku-MQTT kuzo zombiliI-WiFifuthiI-Zigbeeizinhlobo zokuxhumana.

Ngokombono wokuklama uhlelo, i-PC321 inikeza:

Ukulinganisa okunembile kwamandla asekelwe ku-CT
Idatha yesikhathi sangempela efanelekela ukushicilelwa kwe-MQTT
Usekelo lokuqapha ukungenisa/ukuthumela igridi
Ukuhambisana ne-Home Assistant kanye namapulatifomu e-IoT enziwe ngokwezifiso

Kungakhathaliseki ukuthi isetshenziswe njengeIsixazululo se-MQTT samamitha wamandla we-WiFinoma njengengxenye yenethiwekhi yamandla esekelwe ku-Zigbee, i-PC321 ivumela ukufinyelela kwedatha okuqhubekayo kuzo zonke izakhiwo zesistimu ezahlukene.

I-WiFi vs Zigbee: Ukukhetha Isendlalelo Sokuxhumana Esifanele se-MQTT

Kokubili i-WiFi ne-Zigbee zingasebenza ndawonye nezinhlelo zamandla ezisekelwe ku-MQTT, kodwa ngayinye ihlangabezana nezidingo ezahlukene zokufakwa.

Imitha yamandla ye-WiFi MQTTukusetha kulungele amaphrojekthi okuhlala azimele noma ukuhlanganiswa kwe-LAN okuqondile.
Amamitha wamandla e-Zigbeezivame ukuthandwa kumanethiwekhi ezinzwa ezisatshalaliswayo noma uma zihlanganiswa namasango e-Zigbee axhumanisa idatha ne-MQTT.

Ngokunikeza zombili izinketho zokuxhumana, i-PC321 ivumela abaklami bezinhlelo ukuthi bakhethe i-topology efanelana kahle nemikhawulo yephrojekthi yabo ngaphandle kokushintsha ihadiwe yokulinganisa amandla eyinhloko.

Ukusetshenziswa Okusebenzayo Kokulinganisa Amandla Okusekelwe ku-MQTT

Amamitha wamandla ahlakaniphile ane-MQTT avame ukusetshenziswa ku:

Amakhaya ahlakaniphile asekelwe ku-Home Assistant
Izinhlelo zokugcina amandla elanga nezindawo zokuhlala
Amadeshibhodi okuphathwa kwamandla endawo
Ukuzenzakalela okulawulwa umphetho kanye nokwenza ngcono umthwalo
Amaphrojekthi adinga ukuhlanganiswa kwedatha ye-Modbus-to-MQTT

Kuzo zonke lezi zimo, i-MQTT isebenza njengomgogodla othembekile wokushintshaniswa kwedatha yamandla ngesikhathi sangempela.

Izinto Okumelwe Zicatshangelwe Ngabaklami Bezinhlelo Nabahlanganisi

Lapho bekhetha imitha yamandla enamandla e-MQTT, abenzi bezinqumo kufanele bahlole:

Ukunemba kokulinganisa kuzo zonke izigaba zomthwalo
Ukuzinza kokushicilelwa kwedatha ye-MQTT
Ukuthembeka kokuxhumana (i-WiFi noma i-Zigbee)
Ukusekelwa kwe-firmware yesikhathi eside kanye nephrothokholi

Njengomkhiqizi, siklama amamitha kagesi afana ne-PC321 ukuqinisekisa ukuthiukuzinza kwephrothokholi, ukulinganisa okunembile, kanye nokuguquguquka kokuhlanganiswa, okuvumela abahlanganisi bezinhlelo ukuthi bakhe izixazululo ezingandiswa ngaphandle kokuklama kabusha ukwakheka kwazo.

Isiphetho

A imitha yamandla ehlakaniphile ene-MQTTAkuseyona imfuneko ekhethekile—kuyingxenye ebalulekile yezinhlelo zokuqapha amandla zanamuhla kanye nezinhlelo zokwenza izinto ngokuzenzakalela. Ngokuvumela ukufinyelela kwedatha yendawo, ngesikhathi sangempela, kanye nengaxhomekile ohlelweni, ukulinganisa amandla okusekelwe ku-MQTT kusekela izinqumo ezihlakaniphile, ukuzenzakalela okungcono, kanye nokukhula kwephrojekthi yesikhathi eside.

Kwabahlinzeki bezixazululo nabaklami bezinhlelo, ukukhetha imitha yamandla eklanyelwe ukuhlanganiswa kwe-MQTT engqondweni kuqinisekisa ukuthi idatha yamandla ihlala ifinyeleleka, isebenziseka, futhi ivikeleke esikhathini esizayo.

Uma uhlola amamitha wamandla asebenza nge-MQTT kumaphrojekthi wamandla e-Home Assistant noma e-IoT ngokwezifiso, ukuqonda ukwakheka kokuxhumana ezingeni ledivayisi kuyisinyathelo sokuqala sokusetshenziswa okuthembekile.
