Igereranya ry'ibanze hagati y'amashanyarazi akoreshwa na adakora (Active na Passive PoE Power Supply)

Mu buryo bw'umutekano mu nganda, porogaramu zikoresha imashini zireba, no gushyiraho ibikoresho bya IoT,PoE (Ingufu kuri Ethernet)Yabaye igisubizo cy’amashanyarazi gisanzwe bitewe n’ubushobozi bwayo bwo kohereza amakuru n’ingufu ku mugozi umwe wa Ethernet, bigabanya cyane uburyo insinga zikoreshwa n’amafaranga yo kuzishyiraho. Ariko,PoE ikoranaPoE idakorabitandukanye cyane mu mahame agenga imikorere yabyo, uburyo bw'umutekano, n'uburyo bwo kuyikoresha. Guhitamo igisubizo kibi bishobora kwangiza igikoresho, kwangiza umuyoboro w'itumanaho, cyangwa se igihe umurongo w'imikorere udakora.

Itandukaniro rikomeye hagati y’ibyo byombi ni ukumenya niba bishyigikirauburyo busanzwe bwo kuganira ku ngufu.

Ihame ry'imikorere: Ibiganiro by'ubwenge ugereranije no gutanga amashanyarazi mu buryo butaziguye

PoE ikora, izwi kandi nkaPoE isanzwe, yubahiriza neza amahame mpuzamahanga ya IEEE 802.3af, 802.3at, na 802.3bt. Ihame ryayo ry'ingenzi ni"gusuzuma no kuganira mbere yo gutanga amashanyarazi."

Mbere yo gutanga ingufu,Ibikoresho byo Gushakisha Ingufu (PSE), nka switch ya PoE, yohereza ikimenyetso cyo kumenya voltage nke binyuze kuri insinga ya Ethernet kugira ngo hamenyekane niba igikoresho gihujwe gikurikiza amategekoIgikoresho Gikoresha Ingufu (PD)PSE kandi igenzura ibisabwa ku ngufu z'igikoresho kandi irangiza gusabana intoki mbere yo gutanga ingufu za 48V DC. Iyi gahunda ikubiyemo itumanaho ryimbitse no gukurikirana uko ibintu bimeze, kwemeza ko imikorere yacyo ikora neza kandi yizewe.

Ibinyuranye n'ibyo,PoE idakorantabwo irimo inzira iyo ari yo yose yo kumenya cyangwa yo kuganira. Iyo imaze gukoreshwa, PoE injector cyangwa module y'amashanyarazi ihita ishyira voltage idahinduka ku nsinga zimwe na zimwe ziri muri insinga ya Ethernet. Ubu buryo bwo gutanga ingufu "buhora buri kuri" bushingiye gusa ku kugenzura imiterere y'insinga n'ibipimo by'igikoresho, nta bushishozi cyangwa igenzura ry'uburyo gihuye.

Umutekano n'Ubwizerwe: Itandukaniro rikomeye

Icyuho kiri hagati ya Active na Passive PoE kirushaho kugaragara mu bijyanye n'umutekano n'ubwirinzi.

Sisitemu za PoE zikora zikubiyemo uburyo burambuye bwo kurinda, harimo:

• Uburinzi bw'umutwaro urenze urugero
• Uburinzi bw'amashanyarazi make
• Uburinzi bwa polarite isubira inyuma
• Gutahura igikoresho kidakoresha PoE byikora

Iyo igikoresho kidakoresha PoE gihujwe, ingufu zikoreshwa zirenze urugero rwemewe, cyangwa habayeho guhagarara k'umuyoboro, sisitemu ihita ihagarika ingufu kugira ngo hirindwe kwangirika kw'imiyoboro y'itumanaho n'ibikoresho bihujwe.

Byongeye kandi, Active PoE ishyigikiragushyira mu byiciro ingufu n'uburyo ingufu zikoreshwa, bigatuma itanga ingufu zikwiye ku bikoresho bitandukanye nka kamera zo mu nganda, aho abantu binjira nta mugozi, n'inzira za IoT. Bitewe n'uburyo bwa PoE bukoreshwa, gutanga ingufu bishobora kuva kuri hafi15W kugeza 90W, ikubiyemo ibintu byinshi bitandukanye bikoreshwa mu nganda.

Ariko, Passive PoE nta burinzi itanga. Voltage isohoka ikomeza gukora uko ishoboye kose hatitawe ku gikoresho gihujwe. Insinga zidakora neza, ibisabwa kuri voltage idahuye, cyangwa guhuza impanuka n'igikoresho kitari PoE bishobora kwangiza ako kanya ports za Ethernet n'imiyoboro y'imbere, bigatuma ibikoresho binanirwa gukora.

Byongeye kandi, Passive PoE nta bushobozi bwo gucunga ingufu ihari. Iyo ingufu zikenewe n'izitangwa zidahuye, ibibazo nko gutanga ingufu zidahagije, kudakora neza, gushyuha cyane kw'insinga, no kudakora neza kw'ibikoresho bishobora kubaho byoroshye. Kubera iyo mpamvu, muri rusange ntikwiriye ahantu hakorerwa inganda hasaba ubwizigirwa bwinshi no gukomeza gukoreshwa.

Uburyo bwo guhuza no gukoresha porogaramu

Guhuza ni irindi tandukaniro rikomeye riri hagati y’ikoranabuhanga ryombi.

Kubera ko Active PoE ikurikiza amahame mpuzamahanga ya IEEE, swichi, injectors, n'ibikoresho bikoresha imbaraga biva mu nganda zitandukanye bishobora gukorana neza. Uru rwego rwo hejuru rw'imikoranire rutuma Active PoE iba amahitamo meza kuri:

• Imiyoboro y'ikoranabuhanga mu nganda
• Sisitemu zo kureba imashini
• Sisitemu zo kugenzura uruganda
• Itumanaho ry'inganda ridafite umugozi
• Gukoresha IoT mu buryo bunini

Ku rundi ruhande, Passive PoE nta gipimo ngenderwaho cyemewe na bose. Inganda zitandukanye zishobora gukoresha urwego rw'amashanyarazi atandukanye, imikoreshereze y'amapine, n'imiterere y'insinga. Kubera iyo mpamvu, ibikoresho bya Passive PoE akenshi bihuza gusa n'ibikoresho byagenewe imiterere imwe y'amashanyarazi cyangwa ikirango kimwe.

Porogaramu zisanzwe za Passive PoE zirimo:

• Sisitemu zo kugenzura amazu zihendutse
• Gushyira imiyoboro mito y'agateganyo
• Imiterere y'ibikoresho idahindagurika ifite imiterere ihoraho

Umwanzuro

Ku bijyanye n'imikorere y'inganda, ikoranabuhanga rigezweho, gukora ibintu mu buryo bw'ikoranabuhanga, n'izindi porogaramu z'ingenzi,igisubizo cya Active PoE cyujuje ibisabwa kirasabwa cyane. Uburyo bwayo bwo kuganira ku ngufu, uburyo bwo kurinda busesuye, hamwe n'uburyo buhuriweho butuma ikora neza kandi mu buryo bwizewe.

Passive PoE igomba kwitabwaho gusa ku bikoresho bihendutse kandi by'agateganyo aho kuzuzanya kw'ibikoresho byemejwe neza kandi bigagenzurwa neza.Nubwo bimeze gutyo, imiterere y’amashanyarazi, imiterere y’insinga, n’ibisabwa n’ibikoresho bigomba gusuzumwa neza kugira ngo hirindwe kwangirika kw’ibikoresho no kwangirika k’umuyoboro w’itumanaho.
