1. Harsh maindasitiri nzvimbo nzvimbo

Sezvo Ethernet yakagadzirwa pakutanga, yakanga isina kubva pamaindasitiri network network application. Kana ikashandiswa kunzvimbo dzemaindasitiri, yakatarisana nemamiriro ekushanda akaomarara, kupindira kwakakomba kwemutsara, nezvimwewo, izvi zvinozokonzeresa kuvimbika kwayo kudzikire. Munzvimbo yekugadzira, maindasitiri network anofanirwa kuve nekuvimbika kwakanaka, kudzoreredza, uye kuchengetedza. Iko kuita shuwa kuti kana chero chinhu chiri munetwork system chikatadza, hachizokonzerese kuti application, inoshanda sisitimu, kana kunyange network network iparare nekuoma mitezo.

Industrial Ethernet switches dzakagadzirirwa kutarisisa mamiriro akaomarara enzvimbo yeindasitiri, kuitira kuti igone kuchinjika kune nharaunda yeindasitiri uye kuita basa remaindasitiri-giredhi switch.

Mamiriro enzvimbo yemaindasitiri akashata kupfuura nharaunda yakajairwa, zvirinani maererano nekudengenyeka, humidity, uye tembiricha, machinjiro akajairwa haana kugadzirwa kumirisana nemamiriro akasiyana siyana anoonekwa munzvimbo yeindasitiri, machinjiro akajairwa haagone kushanda munzvimbo ino yakaoma. kwenguva yakareba, uye ivo vanowanzoita kukundikana, izvo zvinowedzera mari yekuchengetedza. Kazhinji hazvikurudzirwe kushandisa shanduko dzekutengesa munzvimbo yeindasitiri. Kuti uite kuti shanduko ishandiswe munzvimbo iyi yakaoma, shanduko inogona kuenderana nemamiriro ezvinhu aya inogadzirwa. Kuvimbika kweiyo indasitiri-giredhi switch kunosanganisira kutadza kwemagetsi, kukanganiswa kwechiteshi, relay yekuburitsa alarm, redundant mbiri mbiri DC magetsi ekuisa, inoshanda Circuit dziviriro, otomatiki redunhu breaker kuchengetedza kweanopfuura-voltage uye pasi-voltage, (kuvimbika kunosiyana zvishoma zvichienderana nemuenzaniso. )

Musiyano wekushanda unonyanya kureva: maindasitiri-giredhi switch ari padyo neindasitiri network kutaurirana mune basa, senge interconnection neakasiyana mabhazi emunda, midziyo redundancy, uye midziyo chaiyo-nguva, etc. Musiyano mukuita unonyanya kuratidzwa mukugadzirisa kune kunze kwezvakatipoteredza parameters. Pamusoro penzvimbo dzakawanda dzakaomarara dzakaita semigodhi yemarasha uye ngarava, nharaunda yeindasitiri inewo zvakakosha zvinodiwa maererano neEMI (electromagnetic kuenderana), tembiricha, humidity, uye guruva kuramba. Pakati pavo, pesvedzero yekushisa paindasitiri network network ndiyo yakanyanya kuwanda.

2. Iyo Ethernet network mutoro inorema

Nekuti MAC layer protocol yeEthernet ndeye CSMA/CD, iyi protocol inoita kukakavara panetiweki, kunyanya kana network inotakura yakawandisa, zviri pachena. Kune network yeindasitiri, kana paine huwandu hukuru hwemakakatanwa, iyo data inofanirwa kuendeswazve kakawanda, izvo zvinowedzera zvakanyanya kusava nechokwadi kwekutaurirana pakati pemambure. Mune maindasitiri anodzora network, uku kusagadzikana kubva kune imwe nzvimbo kuenda kune imwe kunozotungamira mukudzikira kwemaitiro ekutonga system.

3. Yakasimba chaiyo-nguva yekushanda kwemaindasitiri data

Mumaindasitiri ekudzora masisitimu, chaiyo-nguva inogona kutsanangurwa sekuyerwa kweiyo system yekupindura nguva kune chiitiko. Mushure mekunge chiitiko chaitika, sisitimu inofanirwa kupindura mukati menguva yakatarwa inogona kunyatsofanoona. Nekudaro, iyo indasitiri ine zvakaomesesa zvinodikanwa zvechaiyo-nguva yekufambisa data, uye dhizaini yedata inowanzopedzwa mukati memakumi emakumi. Uye zvakare nekuda kweiyo CSMA / CD meshini iripo muEthernet, kana kukakavara kuchiitika, iyo data inofanirwa kuendeswazve, iyo inogona kuyedzwa kusvika ka16. Zviripachena, iyi nzira yekugadzirisa kusawirirana inouya nemutengo wenguva. Uye kana paine kukamburwa, kunyangwe angori masekondi mashoma, zvinogona kukonzera kumira kwekugadzira kwese kana midziyo netsaona dzekuchengetedza.

Zvakanaka, zviri pamusoro apa zvakagovaniswa neJHA TECH pane nei maindasitiri mhete network switch ichifanirwa kushandiswa munzvimbo dzemaindasitiri? Sumo yakadzama yenyaya iyi, ndinovimba ichabatsira kune wese!
