1. Pfungwa huru dzekusarudzwa kwePoE switch
1. Sarudza chiyero chePoE switch
Mune yakapfuura PoE column, takataura kuti yakajairwa PoE magetsi emagetsi switch inogona kuona otomatiki kana iyo terminal mune network iri PD mudziyo unotsigira PoE magetsi.
Iyo isiri-yakajairwa PoE chigadzirwa isimba rakasimba rekupa mhando network tambo yemagetsi magetsi, iyo inopa simba kana ichinge yabatidzwa.Naizvozvo, tanga waita shuwa kuti switch yaunotenga ndeye yakajairwa PoE switch, kuti usapisa yekumberi-yekupedzisira kamera.
2. Equipment simba
Sarudza PoE switch zvinoenderana nesimba remudziyo.Kana simba rekutarisa kamera yako iri pasi pe15W, unogona kusarudza PoE switch inotsigira 802.3af standard;kana simba remudziyo rakakura kudarika 15W, saka unoda kusarudza PoE switch ye802.3at standard;kana simba rekhamera rinopfuura 60W, unofanirwa kusarudza 802.3 BT yakajairika high-power switch, kana zvisina kudaro simba harina kukwana, uye midziyo yepamberi haigoni kuunzwa.
3. Nhamba yezviteshi
Parizvino, pane kunyanya 8, 12, 16, uye 24 madoko paPoE switch pamusika.Maitiro ekuzvisarudzira zvinoenderana nenhamba uye simba remberi-yekupedzisira akabatana makamera kuverenga iyo yakazara simba nhamba.Huwandu hwezviteshi zvine simba rakasiyana hunogona kugovaniswa uye kusanganiswa zvichienderana nehuwandu hwemagetsi ekuchinja, uye 10% yetiweki ports yakachengetwa.Ngwarira kusarudza mudziyo wePoE une simba rekuburitsa rakakura kudarika simba rese remudziyo.
Pamusoro pekusangana nezvinodiwa zvemagetsi, chiteshi chengarava chinofanira kusanganawo nedaro rekutaurirana, kunyanya kureba-refu (sekupfuura 100 metres) zvinodiwa.Uye ine mabasa ekudzivirira mheni, kudzivirira kwemagetsi, anti-kupindira, kuchengetedza ruzivo, kudzivirira kupararira kwehutachiona uye kurwisa network.
Kusarudzwa uye kumisikidzwa kwePoE switch
PoE inochinja nenhamba dzakasiyana dzezviteshi
4. Port bandwidth
Port bandwidth ndiyo yakakosha tekinoroji chiratidzo chekuchinja, inoratidzira network yekubatanidza kuita kweiyo switch.Kuchinja kunonyanya kuva nemagetsi anotevera: 10Mbit / s, 100Mbit / s, 1000Mbit / s, 10Gbit / s, nezvimwewo. Paunosarudza poE switch, zvakakosha kutanga kutanga kuenzanisa kufamba kwemotokari kwemakamera akawanda.Paunenge uchiverenga, panofanira kuva nemuganhu.Semuenzaniso, 1000M switch haigone kufungidzirwa zvizere.Kazhinji, chiyero chekushandisa chinenge 60%, iyo inenge 600M..
Tarisa parukova rumwechete zvinoenderana nenetiweki kamera yaunoshandisa, wobva wafungidzira kuti mangani makamera anogona kubatanidzwa kune switch.
Semuenzaniso, imwe kodhi kodhi ye1.3 miriyoni-pixel 960P kamera inowanzo 4M,
Kana ukashandisa 100M chinja, unogona kubatanidza 15 seti (15×4 = 60M);
Iine Gigabit switch, zana nemakumi mashanu (150 × 4 = 600M) anogona kubatana.
Iyo 2-megapixel 1080P kamera inowanzova nerukova rumwechete rwe8M.
Ne 100M chinja, unogona kubatanidza 7 seti (7×8 = 56M);
Ne gigabit switch, 75 seti (75 × 8 = 600M) inogona kubatanidzwa.
5. Backplane bandwidth
Backplane bandwidth inoreva huwandu hwakanyanya hwe data inogona kubatwa pakati peiyo switch interface processor kana interface kadhi nebhasi re data.
Iyo backplane bandwidth inosarudza iyo data yekugadzirisa kugona kweiyo switch.Iyo yakakwirira iyo backplane bandwidth, iyo yakasimba kugona kugadzirisa data uye nekukurumidza iyo data yekuchinjana kasi;kana zvisina kudaro, inononoka iyo data exchange speed.Iyo yekuverengera fomula yebackplane bandwidth yakaita seiyi: Backplane bandwidth = nhamba yemachiteshi × port rate × 2.
Kuverengera muenzaniso: Kana switch ine madoko makumi maviri nemana, uye kumhanya kwechiteshi chega chega kuri gigabit, ipapo iyo backplane bandwidth=24*1000*2/1000=48Gbps.
6. Pakiti yekutumira chiyero
Iyo data mune network inoumbwa nemapaketi e data, uye kugadzirisa kwega yega data packet kunodya zviwanikwa.Chiyero chekufambisa (chinodaidzwawo kuti throughput) zvinoreva huwandu hwemapaketi edata anopfuura nepachikamu chenguva pasina kurasikirwa kwepaketi.Kana iyo throughput ikanyanya kudiki, inozoita network yebhodhoro uye inokanganisa kutapurirana kweiyo network yese.
Chimiro chechiyero chekutakura kwepaketi ndeichi: Kuburikidza (Mpps) = Nhamba ye10 Gigabit ports × 14.88 Mpps + Nhamba yeGigabit ports × 1.488 Mpps + Nhamba ye100 Gigabit ports × 0.1488 Mpps.
Kana iyo yakaverengerwa dhizaini iri shoma pane yekuchinja kwekuchinja, waya-speed switching inogona kuwanikwa, ndiko kuti, chiyero chekuchinja chinosvika padanho rekufambisa data pamutsetse wekutapurirana, nekudaro kubvisa bhodhoro rekuchinja kusvika pamwero mukuru.
