Poe Injector: izita, tsananguro

Poe Injector - ndiyo zvokutanga rezvebonde mudziyo kuti huve nyore zvikuru kugadzwa samambure mano ari zvebhizimisi kana muhofisi. Poe technology (PowerOver Ethernet) inobvumira powering pomumbure midziyo nomukombiyuta pomumbure wire, nokudaro kubvisa midziyo iyi aifanira kuisa nemagetsi nehoro munzvimbo zviri zvakavaomera uye kura simba zvokuyamura.

Ngatimboonai zvakanakira zano akadai Poe injector simba. Kana kuiswa muhofisi Wi-Fi kuwana pfungwa, nomumbure makamera, kana router, unofanira kufunga, ndeipi pedyo nzira yokubudisa (220 volts) kubatanidza simba nerubatsiro vezvikwata kubva midziyo yakadaro. Kazhinji, izvi zvinogona kukutadzisa zvaunogona kusarudza zvikuru. Kakawanda, kuti kuwana zvakanakisisa pamwero Wi-Fi mureza, zvakakodzera kuisa kuwana pfungwa yakakwirira Somuenzaniso, musi pasirin'i. Muchiitiko ichi zvakakodzera, kana kumhanya wiring uye hwokugadza nzira yokubudisa idzva iri kumusoro, kana kubayira unhu chiratidzo uye kuisa midziyo apo simba zvitengeswa achibvumira. Uye kana uchida kuisa zvakarukwa midziyo kunzvimbo dziri kure (padenga, atiki, nezvimwewo), ipapo mari wiring uye nezvigadziko kugadzwa kunogona nokukwirira kwazvo. Kugadzirisa dambudziko iri mureza IEEE 802.3AF akasikwa, izvo zvinoita kuti kushandisa Via Ethernet magetsi iyezvino. Kuti ave nechokwadi chokuti kushanda Namano Zvakwana yaivapo netambo muchikwata rechitatu kana rechishanu. Kusiyana 220 volts, apo magetsi ari kusvitsa vose simba-unoparadza zvokushandisa, Poe injector anovapavhurira simba mudziyo mumwe nomumwe.

Sezvo midziyo yose kombiyuta iri dzinofambiswa nokuda zvakananga uno, kuti Poe mureza achipfeka hutachiwana kubudikidza waya imwe DC voltage kune kusarurama vaviri mune zvakawanda kubva 44 volts kusvika 57 volts. ukoshi Izvi akasarudzwa nokuti zvinogona kuitwa kuti netambo ose yakakoswa peya parunogumira mu refu. Nokuti kupararira kwakaita Magetsi ari waya ndiyo mbiri mbiri, musi mumwe nomumwe wavo akapa vane kuitika mu kuwanda 175 milliamperes (350 Ma mu zvachose). Saizvozvowo, simba rimwe zano akadai Poe injector anogona kusvika 16 watts or. Izvi zvinopfuura kwakakwanira powering pemambure michina.

Kutaura zvazviri, Poe injector - zano kuti transmits mureza iri waya magetsi simba. Kombiyuta inogona revatema mumidziyo midziyo (router) kana kuti configured sezvo yakazvimirira mudziyo. Mukupera zvazvingava, Poe injector kwakabatana kune yakakoswa vaviri uye incision kusvika 220 volts. Pakangotanga Data ndivo mazano kuti mudziyo, uye panguva goho - iri voltage uye mashoko.

In mhedziso, tinoisa kuti Poe zvemichina chakaumbwa semukana kuderedza mari apo Matangiro Aungaita network mumahofisi uye mafekitari. Zvisinei, zvikuru angotanga mukurumbira uye private nemauto, sezvo nyore kubatana pakati mambure michina kwazvo uye hakubvisi zvisingakoshi vakawandisa magetsi.
