Mumakore achangopfuura, kuvandudzwa kwePoE magetsi ekugadzira tekinoroji, kubva pa100M kuenda kuGigabit, kusvika kuGigabit yakazara, kusimudzira kwekusimudzira kwePoE magetsi ekugadzira tekinoroji kuri kuwedzera kusimba nekusimba. Iine akatevedzana mabhenefiti akadai sekurerutsa kuisirwa uye kutumira kwemidziyo yemagetsi, kuchengetedza simba, uye chengetedzo, PoE magetsi yave chinhu chitsva chinodiwa mumamiriro ezvinhu akadai sevhavha isina waya, kuchengetedza kuchengetedza, uye smart grids.
Nekudaro, vazhinji vashandisi vachiri nemibvunzo yakawanda nezve PoE magetsi ekupa. Ngatitarisei matambudziko manomwe akajairika emagetsi ePOE.
1. Ungasarudza sei switch yePoE yekutarisisa kuchengetedza uye kuvharika pasina waya
Kune marudzi akawanda ePoE switches, kubva pa100M kusvika ku1000M, kusvika kugigabit yakazara, pamwe chete nemusiyano pakati pemhando dzisina kutarisirwa uye dzakagadziriswa, uye musiyano muhuwandu hwezviteshi zvakasiyana. Kana iwe uchida kusarudza shanduko yakakodzera, iwe unoda kutarisisa kwakadzama uye kwakadzama. . Tora chirongwa chinoda kutariswa kwepamusoro-tsanangudzo semuenzaniso.
Danho 1: Sarudza yakajairika PoE switch (ona mubvunzo 2 nechikonzero)
Danho 2: Sarudza Fast kana Gigabit Switch
Mumhinduro chaiyo, zvinodikanwa kubatanidza huwandu hwemakamera, uye sarudza maparamendi akadai sekugadziriswa kwekamera, bit rate, uye furemu nhamba. Mainstream yekutarisa michina yevagadziri vakaita seHikvision neDahua vanopa nyanzvi bandwidth kuverenga maturusi. Vashandisi vanogona kushandisa zvishandiso kuverenga inodiwa bandwidth uye sarudza yakakodzera PoE switch.
Danho rechitatu: Sarudza af kana pane yakajairwa PoE switch
Maererano nokutarisisa midziyo simba kusarudzwa. Semuenzaniso, kana kamera yemhando inozivikanwa yakashandiswa, simba iri 12W max. Muchiitiko ichi, shanduko ye af standard inoda kusarudzwa. Simba repamusoro-tsanangudzo dome kamera i30W max. Muchiitiko ichi, zvinodikanwa kushandisa pa-standard switch.
Danho rechina: Sarudza nhamba yezviteshi pane switch
PoE switching inogona kukamurwa kuita 4 ports, 8 ports, 16 ports uye 24 ports zvichienderana nehuwandu hwezviteshi, izvo zvinogona kunyatsoongorora simba, huwandu, nzvimbo yemidziyo, magetsi ekuchinja uye kusarudzwa kwemutengo.
2. Sei chinjiro yePoE yakajairika ichifanira kushandiswa kugovera magetsi?
Chekutanga pane zvese, zvinodikanwa kujekesa mutsauko pakati peyakajairwa PoE switch uye isiri-yakajairwa PoE switch. Iyo yakajairwa PoE magetsi emagetsi switch ine PoE control chip mukati, ine basa rekuona pamberi pesimba rekupa. Kana mudziyo wabatanidzwa, jekiseni rePoE rinotumira chiratidzo kunetiweki kuti rione kana terminal iri munetwork iri PD mudziyo unotsigira PoE magetsi.
Iyo isiri-yakajairwa PoE chigadzirwa isimba rakasimba rekupa network tambo yemagetsi magetsi. Inopa simba kana ichinge yabatidzwa. Hapana danho rekuona. Hazvina mhosva kuti iyo terminal iri PoE powered mudziyo kana kwete, ichapa simba, uye zviri nyore kwazvo kupisa mudziyo wekupinda.
Tora Wangyue Technology MS akateedzana akajairwa PoE switch semuenzaniso. Mushure memagetsi, switch inozoona otomatiki mudziyo une simba. Kana iyo yakaona kuti isiri-PoE powered mudziyo yakabatana, inomira yega magetsi kuchengetedza mudziyo une simba uye kudzivirira kupera simba. Mamiriro emidziyo anoitika, zvichiita kuti simba rekupa simba rive rakachengeteka. Nzira yekuona ndeyotevera. Naizvozvo, yakajairwa PoE switch inofanirwa kushandiswa kune magetsi.
3. Nzira yekusiyanisa sei pakati pePoE yakajairika uye isiri-yakajairika PoE iri nyore kwazvo, ingoshandisa multimeter kuyera. Nzira dziri pasi apa:
Tanga chishandiso, gadzirisa iyo multimeter kune iyo voltage kuyerwa chinzvimbo, uye shandisa mapeni maviri ebvunzo emultimeter kubata mapini emagetsi eiyo PSE mudziyo (kazhinji 1/2, 3/6 kana 4/5, 7/8 ye. iyo RJ45 port). ), kana mudziyo une yakagadzikana kubuda kwe48V kana mamwe ma voltage values (12V, 24V, etc.) akayerwa, isiri-yakajairwa chigadzirwa. Nekuti mukuita uku, iyo PSE haione mudziyo wekugamuchira simba (pano, iyo multimeter), uye yakananga inoshandisa 48V kana mamwe mavheti emagetsi kupa simba.
Sezvineiwo, kana iyo voltage isingakwanisi kuyerwa uye tsono yemultimeter inosvetuka pakati pe2 ne10V, inguva yePOE. Nokuti panguva ino, PSE iri kuedza rutivi rwePD (heino multimeter), uye multimeter haisi PD yepamutemo, PSE haizopi simba, uye hapana mhepo yakagadzikana ichagadzirwa.
4. Simba rePoE rakagadzikana here?
Mukuvaka uye kushandiswa chaiko, pachange paine mamiriro ezvinhu apo iyo PoE switch haigone kupa simba kana kuti magetsi haana kugadzikana. Magetsi ePoE akanyatsogadzikana here?
Muchokwadi, tekinoroji yePoE yakagadziridzwa kwemakore mazhinji, uye iko zvino yave padanho rakakura kwazvo. Iyo yakajairwa PoE simba rekupa yakagadzikana uye yakachengeteka zvakakwana. Mazhinji emamiriro ezvinhu anokonzerwa neiyo yakasarudzwa isiri-yakajairwa PoE switch kana waya yemhando yakadzikira, kana dhizaini yemhinduro pachayo haina musoro, chinhambwe chekupa magetsi hachina kurongeka zvakanaka, kana michina yakawanda yemagetsi yakabatana, uye simba rekushandisa harina kukwana (kunyanya kana chigadziro chekucherechedza chinoshandura moto wekupisa usiku). Nguva). Nokudaro, mukushandiswa kwechokwadi, kana magetsi akawanikwa asina kugadzikana, zvakakosha kuongorora zvikonzero zvekunze kutanga.
5. Iyo yakakwirira simba rePoE magetsi emagetsi, zviri nani here?
Nekuda kwekubuda kwemidziyo ine simba repamusoro-soro senge makamera edome epamusoro-soro uye mafoni evhidhiyo chaiwo, vagadziri vemidziyo yetiweki vari kutsvanzvadzira kugadzira maPoE switch ane simba rakawanda. Nekudaro, zvigadzirwa zvakawanda zvinongoteedzera kuvandudzwa kwesimba rakazara, kufuratira hukama pakati pesimba nehuwandu hwezviteshi. Kana simba racho rakwira, zvinotowedzera kuwedzera mutengo wemuchina. Nekuda kweizvozvo, iyo PoE switch yakasarudzwa nemushandisi haina kunyatsoita uye inodhura-inoshanda.
Naizvozvo, mukutumirwa chaiko, tarisa simba uye huwandu hwemidziyo yePD zvinoenderana nematanho ari mubvunzo 1, uye sarudza yakanyatsokodzera PoE switch.
6. Chinhambwe chekupa magetsi chePoE chinogona kuva mamita zana chete?
Yazvino yazvino inogona kufambiswa kure kure neakajairwa Ethernet tambo, saka nei kureba kwekufambisa kuchigumira kumamita zana?
Icho chokwadi ndechekuti kureba kwekufambisa kure kwePoE switch kunonyanya kuenderana nedanho rekufambisa data. Kana kureba kwekufambisa kuchipfuura 100 metres, kunonoka kwedata uye kurasikirwa kwepaketi kunogona kuitika. Naizvozvo, mukuita chaiko kwekuvaka, kureba kwekufambisa hakufanirwe kudarika 100 metres. Zvakadaro, kwatova nemamwe maPoE switch anogona kusvika kureba kwekutapurirana kwemamita mazana maviri nemakumi mashanu. Semuyenzaniso, Wangyue MS akatevedzana akajairwa PoE switch anoshandisa L-PoE basa, iro rinogona kuwedzera nzvimbo yekufambisa yePoE kusvika pamamita mazana maviri nemakumi mashanu kuti isangane nemagetsi ekureba. Zvinotendwa zvakare kuti nekuvandudzwa kwePoE magetsi ekugadzira tekinoroji munguva pfupi iri kutevera, kureba kwekufambisa kuchawedzerwa mberi.
Yechipiri ndiyo tambo yetiweki. Iyo tambo yetiweki zvakare inosarudza kureba kwemagetsi. Iyo network tambo ine chiyero chenyika inodarika Chikamu 5 uye 6 inogoneka, kunyanya yenyika standard network tambo inodarika Chikamu 6 inogoneka. Vamwe vatengi vanoshandisa tambo dzakachipa uye dzakashata-yemhando yetiweki, dzisingakwanise kuzadzisa chinhambwe chinodiwa kune magetsi, uye nekutaurawo kuti pane dambudziko neFengrunda PoE switch yedu kana PoE splitter, asi patakatumira tekinoroji mainjiniya, kungowana chete. kunze Isu takanga tisina nyaya nePoE switch yedu uye nyaya yakagadziriswa mushure mekutsiva tambo yetiweki.
Kune vanhu vazhinji vasingakwanise kusiyanisa kana network tambo iri yenguva dzose network tambo kana kwete. Pane tambo dzemanyepo dzakawandisa pamusika. Ini ndichakupa nzira shoma dzekuona huchokwadi hwetambo yetiweki, yekutarisa chete:
a. Kune yenguva dzose yenyika standard network tambo, kukosha kwekupokana kuri kure nemamita gumi kusvika ku100 metres isingasviki gumi ohms. Izvi zvinogona kuyerwa zvakananga ne multimeter. Kana yakakura kupfuura 10 ohms, yakadai seyekupikisa kukosha inosvika makumi matatu ohms, ipapo iyi network network inofanira kunge iri fake;
b. Iyo yenguva dzose yenyika yakajairwa network tambo, bhokisi remamita mazana matatu neshanu, mutengo wemusika ungangoita 450-500 yuan (mutengo unotengwa kunze kwenyika uchakwira), shamwari dzinoziva dzinogona kutengawo 430 yuan, asi kana yakaderera pane mutengo uyu. , inhema.
c. Matambo emuchadenga emunyika akajairwa ese imhangura yakachena, kana mhangura isina oxygen, uye zvimwe zvinhu zvakaita semhangura-yakavharwa simbi, copper-clad aluminium, zvichingodaro.
