Eyona ndlela ikhawulezayo yokufaka iseti yeekhithi ze-robotics ezixhunyiweyo kuthungelwano lwesikolo asikokubuza ukuba "ngaba iirobhothi zingayisebenzisa i-WiFi." Kukunika iqela lakho le-IT isicelo esifutshane, esichanekileyo esinokusifunda kube kanye size sisivume. I-IT ithi hayi kwizicelo ezingacacanga kuba izicelo ezingacacanga zidala umngcipheko ongaziwayo. Banike iinkcukacha ezichanekileyo endaweni yoko, uze uphume kuninzi lwengxwabangxwaba.

Yintoni ngokwenene ekufuneka iqela lakho le-IT liyazi

Iibhodi ze-IoT zegumbi lokufundela zizixhobo ezincinci, ezisebenzisa amandla amancinci. Zixhuma kwi-WiFi, zithumele imiyalezo emincinci kwinkonzo yelifu, zize zifumane imiyalelo ibuya. Oko kufana nendlela esebenza ngayo nayiphi na i-sensor eziphethe kakuhle, kwaye kufuna okuncinci kakhulu kunetroli yeelaptop. Guqulela isicelo sakho kwiinkcukacha i-IT ecwangcisa ngazo:

• Ibhendi nokhuseleko: iibhodi zisebenzisa i-WiFi ye-2.4GHz ene-WPA2-PSK. Azixhumi kwii-SSID ze-5GHz kuphela, kwaye uthungelwano oludala lwe-WPA okanye lwe-TKIP aluyi kusebenza. Into eziyifunayo yiqhosha eliqhelekileyo le-WPA2 elabelwe kwangaphambili.
• I-SSID okanye i-VLAN: lolophi uthungelwano ekufuneka zixhume kulo. I-IT ihlala ikhetha i-SSID eyahlukileyo yezixhobo okanye i-VLAN eyahlukanisiweyo, into leyo elungileyo, ngoko yithi wanelisekile yiloo nto.
• Uluhlu lwee-MAC ezivunyelweyo: ibhodi nganye inedilesi ye-MAC engatshintshiyo, ngokungafaniyo neefowuni, ezitshintsha ezazo ngokungakhethiyo. Nikela ngoluhlu olupheleleyo ukuze i-IT ivumele kanye ezo zixhobo kungabikho enye into.
• Ii-port eziphumayo: izixhobo zixhuma ngokuphuma phandle kuphela, ngesiqhelo i-HTTPS ku-443 kunye ne-MQTT ekhuselekileyo ku-8883. Akukho ii-port ezingenayo, akukho ku-forward-a kwee-port, akukho nto ityhilelwe kwi-intanethi.
• I-bandwidth: iklasi ephilayo yeebhodi isebenzisa into engephi, iikhilobhayithi ezimbalwa kwisixhobo ngasinye ngomzuzu kwimiyalezo yobume. Ayizukukhuphisana nokusasazwa kweevidiyo okanye iimviwo eziqhutywa kwi-intanethi.
• Ukwahlulwa kweeklayenti: ukuba iibhodi zithetha nelifu kuphela, i-IT inokushiya ukwahlulwa kweeklayenti kuvuliwe. Yikhankanye nokuba kunjani ukuze kungabikho zothuso.

I-imeyile onokuyikopa uyincamathisele

Guqula iindawo ezikwiibrakethi uze uthumele oku kubani na olawula uthungelwano:

Isihloko: Isicelo sokufikelela kuthungelwano, izixhobo ze-IoT zegumbi lokufundela ezingu-[inani]

Molo [igama], ndiqhuba iklasi yokukhowuda neye-robotics kwigumbi elingu-[igumbi] ngo-[iintsuku namaxesha]. Ndingathanda ukuxhuma iibhodi ze-microcontroller ezingu-[inani] ezisebenza ngeebhetri kuthungelwano ukwenzela izifundo. Ziziphatha njengee-sensor ezilula, kwaye ndineenkcukacha zobuchwepheshe ezingezantsi ukuze uzivume ngaphandle kwengxaki.

• Izixhobo: iibhodi ezingu-[inani], i-WiFi ye-2.4GHz, i-WPA2-PSK kuphela (akukho 5GHz kuphela, akukho WPA1 okanye TKIP).
• Uxhulumaniso: oluphuma phandle kuphela, i-HTTPS 443 kunye ne-MQTT nge-TLS 8883. Akukho kufikelela okungenayo okufunekayo.
• Idatha: iikhilobhayithi ezimbalwa kwisixhobo ngasinye ngomzuzu.
• Ukuchongwa: iidilesi ze-MAC ezingatshintshiyo, uluhlu olupheleleyo luqhotyoshelwe ukuze zivunyelwe.
• Indawo: ndiyavuma ukuba zibe kwi-SSID eyahlukileyo yezixhobo, i-VLAN yeendwendwe, okanye icandelo elahlukanisiweyo ukuba ukhetha njalo.

Ungandazisa ukuba yeyiphi i-SSID neqhosha endinokulisebenzisa, okanye eyona ndlela ilungileyo yokuzifaka kuthungelwano? Ndingazizisa iibhodi kuwe ukuze ubhalise ii-MAC. Enkosi.

Ukuba i-IT ithi hayi, okanye ithi hayi okwangoku

Iimvume zithatha ixesha, kwaye ikota inokuqala phambi kokuba amaxwebhu agqitywe. Akukho nanye kwezo zinto ekufuneka imise isifundo:

• Qala usebenze ungaxhunyanga kwi-intanethi. Abafundi banokwakha baze bavavanye ezo nkqubo zinye kwisimulator yesikhangeli ngaphandle kothungelwano kwaphela. Zama isimulator yeebhloko okanye isimulator ye-verse, uze udlulele kwizixhobo zokwenene xa uthungelwano selulungile.
• Sebenzisa i-hotspot eyodwa. I-router yohambo ye-2.4GHz engabizi okanye i-hotspot yefowuni ikunika uthungelwano lwe-WPA2 olucocekileyo oluphantsi kolawulo lwakho, olukude ngokupheleleyo kwi-LAN yesikolo. Ikwaphila ngcono emva kokusetha kwakhona okubangelwa lu-load shedding kunothungelwano olwabelwanayo.
• Cela i-SSID yeendwendwe. Izikolo ezininzi sele ziqhuba uthungelwano lweendwendwe olwahlukanisiweyo. Izixhobo ezikulo zinokufikelela elifini ngaphandle kokuchukumisa iinkqubo zangaphakathi, into leyo esoloko ilelona "ewe" lulula kwi-IT.
• Zisa iqonga kubo. Ngenkqubo elawulwayo enjenge-sheenIoT kunye nebhodi ye-sheenbot infinity, indlela yokuxhuma iyaziwa kwaye iyaphindaphindeka, ngoko i-IT iyihlola kanye endaweni yokuhlola isixhobo ngasinye.

Ujongo lwemizuzwana engama-60 phambi kokuba uthumele

• Bala izixhobo uze uphawule igumbi, iintsuku namaxesha.
• Hlanganisa iidilesi ze-MAC kwisiqhoboshelo esinye.
• Chaza ngokucacileyo ukuba idatha iphuma phandle kuphela kwaye incinci.
• Nikela ngethuba lothungelwano olwahlukanisiweyo kwasekuqaleni.
• Nika i-IT isicelo esinye, esithe ngqo: yeyiphi i-SSID neqhosha ekufuneka lisetyenziswe.

Thetha ulwimi lothungelwano size isicelo siyeke ukukhangeleka njengomngcipheko siqale ukukhangeleka njengomsebenzi wemizuzu emihlanu. Ikhefu likaJulayi lithuba elihle lokuba i-IT isilungise, ukuze iibhodi zibe zilungele ukuxhuma xa kuqala ikota yesithathu.
