Industrial switches dzakanyatsogadzirirwa kusangana nezvinodiwa zvekuchinjika uye zvinochinjika zvemaindasitiri application uye inopa inodhura-inoshanda maindasitiri Ethernet yekukurukurirana mhinduro.Uye yayo networking mode inonyanya kutariswa pane loop dhizaini.Ringi rine musiyano pakati pemhete imwe chete nemhete dzakawanda.Panguva imwecheteyo, kune yakavanzika mhete mapuroteni akagadzirwa nevagadziri vakasiyana zvichienderana neSTP uye RSTP, senge FRP mhete, turbo mhete, nezvimwe.

Industrial switches ine zvinotevera zvakanakira:

(1) Zero yekuzviporesa mhete network tekinoroji kuti uwane kuvimbika kwakanyanya uye kutendeseka kwekufambiswa kwedata:

Izvi zvisati zvaitika, nguva yekukurumidza yekuzviporesa yekuchinja kwemaindasitiri epasi rose yaive 20 milliseconds.Zvisinei, zvisinei kuti ipfupi sei nguva yekuzviporesa yemhete yemhete kukundikana, kurasikirwa kwepaketi yedata kuchaita kuti pave nenguva yekuchinja, iyo isingagoni kushivirirwa pakutonga kwekuraira.Uye zero yekuzviporesa pasina mubvunzo yakawana budiriro mune iripo matekinoroji kuve nechokwadi chekuvimbika kwepamusoro uye kuvimbika kwedata.Iyo switch inoshandisa nzira mbiri-dhata kuyerera kuti ive nechokwadi chekuti kana network ikatadza, pane nguva dzose nzira imwe yekusvika kwainoenda, kuve nechokwadi chekusavhiringidzwa chekudzora data.

(2) Iyo bhazi-mhando network inoziva kubatanidzwa kwetiweki uye mutsara:

Iyo bhazi-mhando network inobvumira vashandisi kugadzirisa inodzorwa mudziyo.Nekubata iyo yakafanana chaiyo Mac terminal sechinhu chimwe chete, switch inobata mudziyo unodzorwa semudziyo mumwe chete, zvichiita kuti zvishandiso izvi zvitaurirane, kugovana ruzivo, uye kuve nechokwadi chekubatana kwekutonga.

Iyo switch inotsigira akasiyana siyana emabhazi maprotocol uye I/O interfaces kuona network yedata data.Panzvimbo peiyo isiri-yechinyakare point-to-point modhi, wedzera zviwanikwa zvekushandisa network nebhazi.Uyezve, flexible network configuration inogona kuitika, iyo inogona kubatanidzwa zvakananga kune zvigadzirwa zvemumunda zvakadai semamita uye makamera emaindasitiri, zvichibvumira maPLC kuti abatanidzwe kumidziyo yeI / O kure kure, kuderedza zvikuru nhamba yePLC muhurongwa hwose, uye zvakanyanya. kuderedza mari yekubatanidzwa kwehurongwa .Mukuwedzera, kushandiswa kwemaindasitiri kunogona kubatanidzwa mune network monitoring software kuburikidza neWebhu uye SNMP OPC Server kuti iongorore node mamiriro munguva chaiyo, uye yakashongedzerwa nemhosva yealarm mabasa kuti ifambise kuchengetedza uye kutarisira kure.

(3) Fast uye chaiyo-nguva:

Maindasitiri anochinja ane data rekutanga maficha, achibvumira vashandisi kugadzirisa mamwe maturusi seanokurumidza data zvishandiso.Kana data rinokurumidza richionekwa munetiweki yemhete, data yakajairwa ichaita nzira yekukurumidza data.Iyo inodzivirira iyo mamiriro ekuti echinyakare switch haigone kuiswa kune yekudzora yekuraira layer nekuda kwekunyanya kunonoka data.

(4) Yakazvimirira uye inodzoreka dhizaini:

Maindasitiri ekuchinja zvinhu akazvigadzira ega uye ane chigadzirwa chenjere pfuma kodzero.Yayo musimboti software/hardware, zvigadzirwa, uye masevhisi zvese zvakazvimiririra uye zvinodzoreka, kunyanya kuve nechokwadi kuti hapana hutsinye hwekudzokera shure uye kuti hunogona kuramba huchivandudzwa kana kuvharwa.
