Munyika yeIoT, iyo yakajairwa network yekuvaka ndeyekutevera. Kutanga, iyo terminal mudziyo kana sensor inounganidza masaini kana ruzivo. Kune zvishandiso zvisingakwanisi kuwana Internet kana intranet network, sensor inotanga kutumira ruzivo rwakaonekwa kuIoT gedhi, uye ipapo gedhi rinotumira ruzivo kune server; mamwe madivayiri ane mabasa avo ekuwana network, senge nharembozha, iyo inogona kubatanidzwa zvakananga kune server.
Dzimwe nguva, kuitira kuti decompress sevha, tinogona kusarudza mamwe maitiro akareruka ekutaurirana, akadai seMQTT pachinzvimbo cheHTTP, saka sei uchisarudza MQTT pachinzvimbo cheHTTP? Nemhaka yokuti musoro weHTTP protocol yakakura, uye nguva dzose kana data inotumirwa, pakiti inotumirwa kuti ibatanidze / kubvisa TCP, saka iyo data yakawanda inotumirwa, inowedzera huwandu hwehuwandu hwemashoko.
Musoro weMQTT mudiki, uye unogona zvakare kutumira uye kugamuchira iyo inotevera data uchichengetedza iyo TCP yekubatanidza, saka inogona kudzvinyirira iyo yakazara data traffic kupfuura HTTP.
Mukuwedzera, paunenge uchishandisa MQTT, munhu anofanirawo kubhadhara kune izvozvo, achichengetedza TCP yekubatanidza MQTT, data inofanira kutumirwa uye kugamuchirwa. Nokuti MQTT inoderedza kuwanda kwekutaurirana nekuchengetedza TCP connection, kana iwe ukabvisa kubatana kweTCP nguva dzose kana kutaurirana kwemashoko kunoitwa, MQTT ichaita yekubatanidza nekugadzirisa kushandiswa nguva dzose data inotumirwa, seHTTP, asi chigumisiro chichawedzera kutaurirana. volume.
Unoda kudzidza zvakawanda nezve iyo IoT gedhi inoshanda? Inzwa wakasununguka kubata Feasycom Ltd.
