Kuvandudzwa kwekirasi yesainzi yekombuta muchikoro cheRussia paMalinka: yakachipa uye inofara

Iko hakuna nyaya inosiririsa munyika kupfuura dzidzo yeRussia IT muavhareji chikoro

Nhanganyaya

Dzidzo muRussia ine matambudziko akawanda akasiyana, asi nhasi ini ndichatarisa nyaya isingawanzokurukurwa kakawanda: IT dzidzo kuchikoro. Muchiitiko ichi, ini handisi kuzobata pamusoro penyaya yevashandi, asi ndichangoitisa "kuedza kwekufunga" uye edza kugadzirisa dambudziko rekushongedza kirasi yesainzi yekombuta neropa shoma.

Matambudziko

1. Muzvikoro zvizhinji zvesekondari (kunyanya mumapurovhinzi), makirasi esainzi emakombuta haana kuvandudzwa kwenguva yakareba, pane zvikonzero zvakasiyana zveizvi, ini ndicharatidza zvemari: kushomeka kwemajekiseni anonangwa kubva kumabhajeti ekanzuru, kana bhajeti yechikoro pachayo haibvumiri kuvandudzwa.
2. Kune zvakare chimwe chinhu, kunze kwenguva, chinokanganisa mamiriro emidziyo - vadzidzi. Kazhinji, iyo system unit inowanikwa padyo nepedyo nemudzidzi, saka munguva dzekufinhwa uye pasina ari kuona, vamwe vanhu vanogona kukanda system unit kana kunakidzwa nayo nedzimwe nzira.
3. Kusadzora komputa iyo mudzidzi ari kushanda pairi. Somuenzaniso, mukirasi yevanhu 20 (chaizvoizvo nhamba iyi inosvika makumi matatu kana kupfuura), basa rakapiwa pamifananidzo yepakombiyuta kana pakunyora purogiramu. Muchiitiko ichi, chidzidzo chaizoenda nerufaro zvikuru kana mudzidzisi akawana mukana wekuona zviri kuitika pazvikirini zvevadzidzi, pane kumhanya-mhanya kirasi yose akatarisa pamonitor yemunhu wese uye kumira kwemaminitsi mashanu kuti atarise.

Raspberry solution

Iye zvino: kubva pakuchema kusvika pakuita. Iwe unogona kunge watonzwisisa kuti mhinduro yandichakurudzira kumatambudziko ari pamusoro ndeye raspberry pi, asi handei poindi.

1. Mitengo yemidziyo ichatorwa pamitengo yekutengesa, ne saiti mutengesi mukuru wemubatanidzwa - izvi zvakaitwa chete nekuda kwekureruka uye, sezvineiwo, mumamiriro ezvinhu chaiwo, kana uchitenga michina, mitengo yemitengo yakaderera.
2. Mukirasi yangu yekufungidzira, ndichaita fungidziro: mudzidzisi akagadzirira kugara uye kudzidza mamwe ma nuances ane chekuita nekuvandudza michina uye nekuwedzera kugona kweuyu mudzidzisi chaiye.

Saka ngatitangei. Pfungwa yose yakabatana nekushandiswa kweraspberries inobva pane zvakanakira zvakanakira: compactness, kuwanika kwehama, kuderedza kushandiswa kwesimba.

Base

1. Ngatitangei kuti vangani uye rudzii rwe raspberries tinoda kutenga. Ngatitorei avhareji yenhamba yemotokari yekirasi: 24 + 1 (ini ndichakuudza kuti nei izvi zvishoma gare gare). Tichazvitora Raspberry Pi 3 Mhando B +, kureva, anenge 3,5 zviuru rubles. pachidimbu kana 87,5 zviuru rubles. kwe25 zvidimbu.
2. Tevere, kuisa mabhodhi isu tinogona kutora telecommunications cabinet, semuenzaniso, Cabeus avhareji mutengo ~ 13 zviuru rubles. Panguva imwecheteyo, tinogadzirisa dambudziko rinotaurwa mundima yechipiri, kureva kuti, zvinokwanisika kubvisa chikamu chemidziyo kubva kuvadzidzi uye kuzvidzora mumuviri chero nguva.
3. Muzvikoro zvakawanda, kune chikwereti cheBazi reDzidzo, iyo inodiwa network network yakaiswa: switch, routers, nezvimwewo, zvisinei, nekuda kwekuchena kwekuvaka, isu tichabatanidza zvinhu izvi mune rondedzero yezvinodiwa. Ngatitorei shanduko yakapusa, chinhu chikuru ndechekuti kune nhamba yakakwana yezviteshi - kubva makumi maviri nematanhatu (26 vadzidzi, 24 yakakosha, 1 yemudzidzisi), ndingasarudza D-Link DES-1210-28, iyo inowedzera imwe 7,5 zviuru rubles. nemari yedu.
4. Ngatitorei zvakare yakapfava router, sezvo chinonyanya kukosha kwatiri ndechekuti inobata huwandu hwemichina nekumhanya kwakanaka, ngatitorei. microtic - ndiyo imwe + 4,5 zviuru rubles.
5. Rumwe ruzivo: 3 zvakajairika network mafirita HAMA 47775 + 5,7 zviuru rub. Patch tambo 25 pcs. ye wiring kubva pakuchinja 2 m. Greenconnect GCR-50691 = +3,7 zviuru rub. Memory makadhi ekuisa OS pane raspberries, kadhi risiri pasi pekirasi 10 Transcend 300S microSDHC 32 GB imwe +10 zviuru rubles. kwe25 zvidimbu.
6. Sezvaunonzwisisa, kudzidzisa akati wandei makirasi kubva kwakasiyana kufanana kunoda kupfuura 32 GB. kunzvimbo yebasa, saka nzvimbo yekuchengetera ine basa remudzidzi ichagoverwa. Kuti tiite izvi, ngatitorei Synology Disk Station DS119j +8,2 zviuru rub. uye terabyte dhisiki yayo Toshiba P300 +2,7 zviuru rub.

Mari yese: RUB 142 (kana uchifunga nezvemitengo yekutengesa).

Peripherals

Ini ndichabva ndachengeta kuti iyo inotevera runyorwa inofunga nezve chokwadi chekuti kiyibhodhi, mbeva uye mamonitor atovepo - chete dambudziko rekuvabatanidza kumuchina uri kure rinogadziriswa. Zvakare, ini ndinoita fungidziro yekuti chigadziko chiri mukamuri imwe chete chinhambwe chisingasviki 5-10 metres, nekuti kana iri chinhambwe chikuru iwe uchafanirwa kutenga tambo dzeHDMI nevanodzokorora.

1. Sezvambotaurwa, kubatanidza mamonitor kune raspberry pi isu tichada HDMI tambo. Ngatitorei mamita mashanu FinePower HDMI + 19,2 zviuru rub. kwe24 zvidimbu.
2. Kuti ubatanidze mbeva nekhibhodi tinoda USB yekuwedzera tambo Gembird USB +5,2 zviuru rub. uye splitters DEXP BT3-03 +9,6 zviuru rub.

Mari yese: RUB 34 (kana uchifunga nezvemitengo yekutengesa).

Pfupiso yezvikamu: RUB 176 (kana uchifunga nezvemitengo yekutengesa).

Software level

SeOs yevadzidzi, ndinofunga zvakakodzera kusarudza yakajairwa Raspbian, sezvo kunyangwe iye zvino zvikoro zvakawanda zvinoshandisa Linux kugovera (zvinofanirwa kutaura kuti izvi zvinowanzoitika nekuda kwezviwanikwa zvishoma, uye kwete nekuti vanonzwisisa kuti zvinobatsira). Kupfuurirazve, pane raspbian iwe unogona kuisa zvese zvaunoda kuti ugone chirongwa chekudzidzisa: hofisi yemahara, geany kana imwe kodhi kodhi, pinta, kazhinji, zvese zvakatoshandiswa ikozvino. Chinhu chinonyanya kukosha kugadzirisa Veyon kana software yakafanana, sezvo inogadzirisa dambudziko kubva pachikamu chechitatu, ichikubvumira kudzora zviri kuitika pamakombiyuta emudzidzi, uye inobvumirawo mudzidzisi kuti aratidze chinyorwa chake, semuenzaniso, kune mharidzo.

Iyo software inodiwa kumudzidzisi, kazhinji, haina kunyanya kusiyana nesoftware inodiwa kumudzidzi. Chinhu chinonyanya kukosha kutaurwa maererano nemudzidzisi ndechekuti 25th raspberry pi board ichidiwa. Muchokwadi, hazvisi zvekumanikidzwa, asi kwandiri chinangwa chayo chakakosha. Ndinofunga zvakakodzera kuisa pi hole - yakakosha software inogona kubatsira mudzidzisi kutarisa network yevadzidzi.

Afterword

Ichi chinyorwa chakafanana nemutsara:

Akadaro, asingatauri chero ani zvake.

Ndinofunga zviri pachena kune wese kuti kuverenga uye mitengo murugwaro urwu hazvina kururama, zvisinei, kubva kwavari iwe unogona kunzwisisa kuti haudi miriyoni kana hafu yemari iyi kuti uvandudze kirasi yesainzi yekombuta muzvikoro zvekare zveRussia, kuwedzera kunyaradza semudzidzi, uye mudzidzisi.

Nyora mumashoko zvaungashandura kana kuwedzera mukirasi ino yekufungidzira, chero kushoropodza kunogamuchirwa.
