I-MQTT yinkqubo elula yokuthumela imiyalezo evumela izixhobo ezincinci ukuba zabelane ngedatha ngaphandle kokuthetha omnye komnye ngokuthe ngqo. Isixhobo sipapasha umyalezo omfutshane kumxholo onegama, inkqubo esembindini ebizwa ngokuba yibroker iwubambe, ize nantoni na ebhalisele loo mxholo ifumane ikopi. Owona mfanekiso ulula yibhodi yezaziso yegumbi lokufundela: uncamathisela inqaku phantsi kwesihloko, ize nabani na onomdla kweso sihloko alifunde xa ethuba lifika.

Elo cebo linye lihlanganisa phantse yonke into oyifunayo ukuze uyicacise kwiklasi. Okuseleyo kweli nqaku kuchaza iinxalenye ezine ezisebenzayo ngamagama alula.

Yibhodi yezaziso, ayingomnxeba

Umnxeba ufuna abantu bobabini babe kumnxeba ngaxeshanye. Uninzi lweeprojekthi zee-sensor zasegumbini lokufundela alunjalo. I-sensor yobushushu inokuthumela isilinganiso rhoqo emva kwemizuzwana elishumi, kodwa ideshbhodi ebonisa eso silinganiso isenokuba ivaliwe, okanye umfundi asenokuyivula emva kweyure.

I-MQTT iyisombulula le nto ngendlela efana neyebhodi yezaziso. I-sensor incamathisela inqaku layo ize ihambe. Ideshbhodi ifunda ibhodi nanini na xa ijongile. Akukho cala kufuneka lazi ukuba elinye likhona, okanye libe livukile ngexesha elinye. Oku kubizwa ngokuba kukupapasha nokubhalisela, kwaye sisizathu sokuba ibhodi enye encinci ikwazi ukondla iiskrini ezininzi ngaphandle kokuba nayiphi na kuzo ixhunywe ngeentambo.

Imixholo ziileyibhile nje

Umxholo sisihloko oncamathisela phantsi kwaso inqaku lakho. Ubhalwa njengendlela enee-slash, ngoko ufundeka njengesakhelo sefolda:

• classroom/temperature
• lab/door/status
• greenhouse/soil/moisture

La magama uzenzela wena; akukho luhlu lumiselweyo. Umbhaliseli ucela kanye isihloko asifunayo. Kukwakho neempawu ezimela nantoni na, ngoko ideshbhodi inokubhalisela ku-classroom/# ize ifumane onke amanqaku ancanyathiselwe phantsi kwesihloko segumbi lokufundela ngaxeshanye. Amagama alungileyo emixholo lelona siko liluncedo ukulifundisa, kuba indlela ecocekileyo yokunika amagama igcina iprojekthi ifundeka xa kukho ii-sensor ezingamashumi amabini endaweni yezimbini.

I-broker ihlala embindini

I-broker yinkqubo eqhuba ibhodi yezaziso. Wonke umyalezo uya kwi-broker kuqala, ize i-broker iwudlulisele kubo bonke abo babhalisileyo. Izixhobo zithetha ne-broker kuphela, azize zithethe omnye komnye, into leyo egcina isixhobo ngasinye silula kwaye singabizi. Kwiprojekthi yesikolo i-broker ihlala iyiseva encinci okanye inkonzo egcinwe kwenye indawo; abafundi abafane bayibone, bakhomba nje ibhodi yabo nedeshbhodi yabo kwidilesi enye.

Imiyalezo egcinwayo kunye nomyolelo wokugqibela

Zimbini iimpawu ezongezelelweyo ezivela rhoqo, kwaye zombini ziyangqinelana nomfanekiso webhodi yezaziso.

Umyalezo ogciniweyo linqaku elincanyathiselweyo elihlala lihleli. Ngesiqhelo umyalezo udluliswa kanye ube uphelile. Ukuba inqaku ligciniwe, i-broker igcina elona lisandul' ukufika, ngoko ideshbhodi evulwa kamva ibona ngoko nangoko ixabiso langoku endaweni yeskrini esingenanto. Oku kulungele ngokugqibeleleyo isilinganiso esifana nobushushu bangoku.

Umyolelo wokugqibela linqaku i-broker elipapashayo egameni lesixhobo ukuba eso sixhobo siphuma ngequbuliso. Livumela ideshbhodi ukuba ibonise i-sensor njengengaxhunyiwe kwangoko xa ithe cwaka, endaweni yokubonisa inani elidala ngonaphakade. Ezi mpawu zimbini kunye zizizathu zokuba iskrini se-IoT sikwazi ukuzijonga.

Kutheni iideshbhodi ziyisebenzisa, nokuba udibana nayo phi eklasini

Iideshbhodi zixhomekeke kwi-MQTT kuba imiyalezo mincinci, iyakwazi ukujongana ne-wifi engazinzanga oyifumana egumbini lokufundela lokwenene, kwaye i-broker enye inokunceda izixhobo ezininzi ngaxeshanye. Xa ibhodi ye-sheenbot ifunda i-sensor ize iskrini esibukhoma sihlaziyeke emva komzuzwana, kukupapasha nokubhalisela okuthwele elo nani. Iideshbhodi zethu ze-sheenIoT zisebenza ngale ndlela kanye, zibhalisela imixholo ekhethwa ngabafundi bakho.

Awuzidingi izixhobo eziphathekayo ukufundisa le ngcinga. Abafundi banokupapasha baze bafumane imiyalezo kwisimulator ye-verse kuqala, baze badlulele kwibhodi yokwenene xa umfanekiso wengqondo sele uzinzile. Ukuba ungathanda ukuyibona yakhiwa ukusuka ekuqaleni ukuya ekugqibeleni neklasi, iiworkshop ze-robotics zeeholide zibandakanya iprojekthi epheleleyo ukusuka kwi-sensor ukuya kwideshbhodi.

Umfanekiso wengqondo wemigca emihlanu onokuwunika abafundi

• Ukupapasha kuthetha ukuncamathisela inqaku ebhodini.
• Ukubhalisela kuthetha ukucela ukuxelelwa xa kuvela amanqaku phantsi kwesihloko.
• Umxholo sisihloko, esibhalwa ngolu hlobo classroom/temperature.
• I-broker yibhodi yezaziso ekwabelwana ngayo ngumntu wonke.
• Ukugcinwa kuthetha ukuba inqaku lokugqibela lihlala lincanyathisiwe kumfundi olandelayo.

Gcina olo luhlu eludongeni kwizifundo ezimbalwa zokuqala. Xa abafundi sele bekwazi ukwalatha ibhodi yezaziso baze bathi ngubani oncamathiselayo nangubani ofundayo, igama elithi MQTT liyeka ukuba ligama elinzima libe yinkcazo yento abasele bekwazi ukuyicinga ngengqondo.
