Mumasisitimu ekuchengetedza maindasitiri, mashandisirwo ekuona kwemuchina, uye kuiswa kwemidziyo yeIoT,PoE (Simba pamusoro peEthernet)rave mhinduro huru yemagetsi nekuda kwekugona kwaro kutumira data nesimba pamusoro petambo imwe chete yeEthernet, zvichideredza zvakanyanya kuoma kwetambo uye mari yekuisa. Zvisinei,Active PoEuyePassive PoEZvinosiyana zvakanyanya mukushanda kwavo, nzira dzekuchengetedza, uye mamiriro ekushandisa. Kusarudza mhinduro isiriyo kunogona kukonzera kukuvara kwemudziyo, kukundikana kwenetwork, kana kutotadza kushanda kwemutsetse wekugadzira.
Musiyano mukuru pakati pezviviri izvi uri pakuti zvinotsigira here kana kuti kwetenzira yakajairika yekutaurirana kwesimba.
Nheyo Yekushanda: Kukurukurirana Kwakangwara vs. Kutumira Simba Zvakananga
Active PoE, inozivikanwawo sePoE yakajairika, inoenderana zvakanyanya nezvinodiwa zvepasi rose zveIEEE 802.3af, 802.3at, uye 802.3bt. Musimboti wayo mukuru ndewekuti"ona uye taurirana usati wapa magetsi."
Vasati vapa simba,Midziyo Yekutsvagisa Simba (PSE), senge switch yePoE, inotumira chiratidzo chekuona voltage yakaderera kuburikidza netambo yeEthernet kuti ione kana mudziyo wakabatana uchienderana nezvinodiwa nevatengi.Mudziyo Une Simba (PD)PSE inoongororawo zvinodiwa pamagetsi emuchina uye inopedzisa kubatana maoko neprotocol isati yapa simba re48V DC. Maitiro aya anosanganisira kutaurirana kwakangwara uye kutarisa mamiriro nguva dzose, kuve nechokwadi chekuti mashandiro akachengeteka uye akavimbika.
Mukupesana ne,Passive PoEHaisanganisiri maitiro ekuona kana ekutaurirana. Kana yangobatidzwa, PoE injector kana power module inoisa voltage yakagadzika pakarepo kune waya dzakatarwa dziri muEthernet cable. Iyi nzira yekuendesa simba "inogara yakabatidzwa" inotsamira pakusimbisa magadzirirwo ewaya nemaoko uye zvinodiwa zvemudziyo, pasina dziviriro yakangwara kana kuongororwa kwekuenderana.
Kuchengetedzeka uye Kuvimbika: Misiyano Yakakosha
Musiyano uripo pakati peActive nePassive PoE unonyanya kuoneka panyaya yekuchengetedzeka nekuvimbika.
Masisitimu eActive PoE anosanganisira nzira dzakakwana dzekudzivirira, dzinosanganisira:
- Dziviriro yekuremerwa zvakanyanya
- Dziviriro yepfupi-yedunhu
- Dziviriro yekudzivirira polarity yekudzokera shure
- Kuonekwa otomatiki kwemudziyo usiri wePoE
Kana mudziyo usiri wePoE wakabatana, simba rinoshandiswa kupfuura muganho unobvumirwa, kana kuti pakaitika short circuit, system inodzima magetsi otomatiki kudzivirira kukuvara kwe network interfaces nemidziyo yakabatana.
Pamusoro pezvo, Active PoE inotsigirakupatsanura simba uye kugoverwa kwesimba rinoshanduka, zvichiita kuti ikwanise kupa simba rakakodzera kumidziyo yakasiyana-siyana yakadai semakamera eindasitiri, nzvimbo dzekuwana mawaya dzisina waya, uye magedhi eIoT. Zvichienderana nePoE standard inoshandiswa, simba rekutumira magetsi rinogona kubva paanenge15W kusvika 90W, inosanganisira mhando dzakasiyana-siyana dzemashandisirwo emaindasitiri.
Zvisinei, Passive PoE haipe dziviriro yakavakirwa mukati. Voltage inobuda inoramba ichishanda pasinei nemudziyo wakabatana. Kusashanda zvakanaka kwewaya, zvinodiwa zvevoltage zvisina kuenderana, kana kubatana netsaona nemudziyo usiri wePoE zvinogona kukanganisa maports eEthernet nemidziyo yemukati, zvichikonzera kutadza kushanda kwemidziyo.
Uyezve, Passive PoE haina simba rekugadzirisa magetsi. Kana kudiwa kwemagetsi nekuwanikwa kwawo zvikasaenderana, matambudziko akadai sekushaya simba remagetsi, kushanda kusina kugadzikana, kupisa kwetambo, uye kusashanda zvakanaka kwemidziyo zvinogona kuitika zviri nyore. Nekuda kweizvozvo, kazhinji haikodzeri nzvimbo dzemaindasitiri dzinoda kuvimbika kwakanyanya uye kushanda nguva dzose.
Mamiriro Ekushanda Nekushandisa
Kuenderana ndeimwe musiyano mukuru pakati pematekinoroji maviri aya.
Nekuti Active PoE inotevedzera mitemo yeIEEE inozivikanwa pasi rose, maswichi, majekiseni, uye zvishandiso zvinoshandisa simba kubva kuvagadziri vakasiyana zvinogona kushanda pamwe chete zvakanaka. Kushanda pamwe chete uku kwakanyanya kunoita kuti Active PoE ive sarudzo inosarudzwa ye:
- Manetiweki ekushandisa otomatiki emaindasitiri
- Masisitimu ekuona kwemuchina
- Masisitimu ekutarisa mafekitori
- Kutaurirana kwemaindasitiri kusina waya
- Kuiswa kweIoT kwakakura
Kune rumwe rutivi, Passive PoE haina mwero unogamuchirwa nevanhu vose. Vagadziri vakasiyana vanogona kushandisa ma voltage levels akasiyana, ma pin assignments, uye wiring configurations. Nekuda kweizvozvo, michina yePassive PoE inowanzo shanda chete nemidziyo yakagadzirirwa simba rimwe chete kana brand.
Maitiro akajairika ePassive PoE anosanganisira:
- Masisitimu ekutarisa dzimba asingadhuri
- Kuiswa kwetiweki diki kwenguva pfupi
- Kuisa zvinhu zvinodhura zvishoma zvine michina yakatarwa
Mhedziso
Kune otomatiki yemaindasitiri, kuona kwemuchina, kugadzira zvinhu zvakangwara, nezvimwe zvinoshandiswa zvakakosha pabasa,mhinduro yeActive PoE inoenderana nezvinodiwa inokurudzirwa zvikuru. Kutaurirana kwayo nesimba zvine hungwaru, maficha akazara ekudzivirira, uye kushanda kwayo kwakabatana zvinovimbisa kushanda kwakachengeteka uye kwakavimbika.
Passive PoE inofanira kungotariswa chete kana paine kushandiswa kwenguva pfupi uye kwakaderera uko kuenderana kwemidziyo kwakasimbiswa zvizere uye kwakanyatsodzorwa.Kunyangwe mumamiriro ezvinhu akadai, zvinodiwa pamagetsi, magadzirirwo ewaya, uye zvinodiwa nemidziyo zvinofanirwa kuongororwa zvakakwana kudzivirira kukuvara kwemidziyo uye kutadza kushanda kwenetwork.
