<\/h2>\n

I. Contexte<\/h2>\n<\/div>\n
Dans divers sc\u00e9narios d'application industrielle, la collecte et l'analyse efficaces des donn\u00e9es constituent un d\u00e9fi majeur pour les entreprises industrielles d'aujourd'hui. Comment utiliser efficacement les donn\u00e9es collect\u00e9es ? \u00c0 la recherche de solutions fiables, des plateformes IoT en nuage ont vu le jour. Actuellement, l'industrie de l'IdO utilise diverses technologies de collecte et m\u00e9thodes d'analyse, la plus courante \u00e9tant la combinaison de l'informatique en nuage + des plateformes en nuage IdO + des appareils. Gr\u00e2ce \u00e0 l'analyse des donn\u00e9es et au contr\u00f4le des appareils, les utilisateurs\/entreprises peuvent augmenter les niveaux d'automatisation, r\u00e9duire les co\u00fbts et am\u00e9liorer l'efficacit\u00e9.<\/span><\/div>\n
\u00c0 l'\u00e8re de l'internet, 80% des donn\u00e9es mondiales proviendront de l'IdO. Les secteurs traditionnels et les industries \u00e9mergentes exploiteront des donn\u00e9es pr\u00e9cieuses pour soutenir le d\u00e9veloppement de nouveaux march\u00e9s et conduire de nouvelles initiatives commerciales, en parvenant \u00e0 r\u00e9duire les co\u00fbts et \u00e0 am\u00e9liorer l'efficacit\u00e9.<\/span><\/div>\n
\n

II. Surveillance de l'environnement<\/h2>\n<\/div>\n
La surveillance de l'environnement implique la collecte de donn\u00e9es de mesure au niveau physique. Ces mesures fournissent une base solide pour l'analyse des conditions environnementales. Elles constituent la base de la protection de la sant\u00e9 humaine, de la r\u00e9alisation d'un d\u00e9veloppement environnemental durable et de l'aide apport\u00e9e aux gouvernements pour formuler des politiques pertinentes.<\/span><\/div>\n
En ce qui concerne la valeur commerciale des plates-formes en nuage et des dispositifs de surveillance de l'environnement, le d\u00e9veloppement \u00e9conomique rapide de la Chine et sa transition d'un pays industriel \u00e0 un pays de technologie avanc\u00e9e ont permis d'accorder une grande attention aux questions de surveillance de l'environnement.<\/span><\/div>\n
\n

III. Connexion aux plateformes IoT en nuage<\/h2>\n<\/div>\n
Prendre le DTU (Unit\u00e9 de transfert de donn\u00e9es<\/strong><\/a>) \u00e0 titre d'exemple, ce dispositif terminal de communication IoT commun sert de passerelle, acc\u00e9dant aux serveurs cloud par le biais de ports s\u00e9rie ou de technologies sans fil.<\/span><\/div>\n
Actuellement, les DTU jouent un r\u00f4le majeur dans la collecte de donn\u00e9es. Une proportion importante d'utilisateurs de plateformes IoT utilise ce type d'appareil pour la connectivit\u00e9, comme nos DTU200, DTU300, etc. qui peuvent r\u00e9pondre \u00e0 diff\u00e9rentes exigences et sc\u00e9narios d'utilisation. G\u00e9n\u00e9ralement, les dispositifs se connectent \u00e0 des \u00e9quipements esclaves ModBus \u00e0 l'aide de ports RS422\/232\/485, pour des applications telles que l'allumage des lumi\u00e8res, la surveillance de la temp\u00e9rature de l'air, les compteurs \u00e9lectriques, les compteurs d'eau, les compteurs de gaz, le contr\u00f4le des \u00e9quipements \u00e9lectriques, etc. Ces produits sont \u00e9galement utilis\u00e9s dans des sc\u00e9narios n\u00e9cessitant des zones de couverture \u00e9tendues, une faible consommation d'\u00e9nergie et une transmission sans fil.<\/span><\/div>\n
Une fois les appareils connect\u00e9s aux plateformes IoT et les donn\u00e9es accumul\u00e9es, l'analyse devient possible - en comparant les diff\u00e9rents co\u00fbts par ann\u00e9e, par mois et par jour pour trouver des moyens de r\u00e9duire les d\u00e9penses tout en fournissant des donn\u00e9es puissantes pour la planification et les pr\u00e9visions futures de l'entreprise.<\/span><\/div>\n

\"4b063e2591bb228445fec71f6968e341\"IV. R\u00f4le dans l'exploration p\u00e9troli\u00e8re<\/h2>\n<\/div>\n
Avec la mont\u00e9e en puissance de la Chine, la demande d'extraction de ressources min\u00e9rales s'accro\u00eet de jour en jour, l'exploitation de l'\u00e9nergie p\u00e9troli\u00e8re \u00e9tant particuli\u00e8rement importante. Cependant, les gisements de p\u00e9trole sont relativement dispers\u00e9s et les m\u00e9thodes traditionnelles d'extraction du p\u00e9trole ne sont plus adapt\u00e9es \u00e0 la gestion et \u00e0 la planification des projets. Des m\u00e9thodes plus efficaces sont n\u00e9cessaires de toute urgence pour r\u00e9pondre \u00e0 la demande croissante d'extraction.<\/span><\/div>\n
Comment y rem\u00e9dier ? Pour r\u00e9pondre aux exigences de l'extraction, l'exploration a \u00e9volu\u00e9 pour combiner la technologie de communication 4G avec des DTU industriels afin de r\u00e9aliser une surveillance et un fonctionnement \u00e0 distance sans fil. En connectant la 4G, les appareils DTU et les syst\u00e8mes d'exploitation, le syst\u00e8me peut surveiller l'\u00e9quipement en ligne et recueillir des donn\u00e9es sur les puits de p\u00e9trole, la tension, la temp\u00e9rature de la t\u00eate de puits, la pression d'entr\u00e9e, etc. Gr\u00e2ce \u00e0 la technologie de transmission d'informations stable des trois principaux op\u00e9rateurs de t\u00e9l\u00e9communications, les donn\u00e9es peuvent \u00eatre t\u00e9l\u00e9charg\u00e9es en temps r\u00e9el vers la plateforme de gestion des appareils correspondants pour \u00eatre analys\u00e9es et jug\u00e9es. Cela permet de d\u00e9tecter \u00e0 temps les d\u00e9faillances des puits de p\u00e9trole, les pannes de moteur, les probl\u00e8mes de tension et d'autres anomalies. Lorsque des probl\u00e8mes anormaux surviennent, le DTU peut d\u00e9clencher des alarmes via le r\u00e9seau 4G et ex\u00e9cuter des mesures d'urgence telles que l'arr\u00eat, le red\u00e9marrage ou la mise hors tension de l'\u00e9quipement d\u00e9fectueux en fonction de param\u00e8tres pr\u00e9d\u00e9finis. L'utilisation de DTU+4G dans les domaines industriels permet au personnel d'op\u00e9rer \u00e0 distance, de contr\u00f4ler le d\u00e9marrage et l'arr\u00eat de l'\u00e9quipement, d'assurer la s\u00e9curit\u00e9 du personnel et d'\u00e9tendre la gamme des op\u00e9rations contr\u00f4lables.<\/span><\/div>\n
\n

V. Autres domaines<\/h2>\n<\/div>\n
Les dispositifs DTU ont des applications dans diff\u00e9rents domaines :<\/span><\/div>\n
\n
    \n
  1. Dans le secteur de l'\u00e9nergie, ils ont atteint un stade relativement mature, bien que la demande continue \u00e0 augmenter. La distribution d'\u00e9nergie, le transport d'\u00e9nergie et la surveillance du r\u00e9seau \u00e9lectrique pr\u00e9sentent encore un potentiel commercial important. En raison de la nature particuli\u00e8re de l'industrie de l'\u00e9nergie, les protocoles de transmission sont restreints et, en g\u00e9n\u00e9ral, des DTU sp\u00e9cifiques \u00e0 l'\u00e9nergie sont adopt\u00e9s.<\/li>\n<\/ol>\n<\/div>\n
    \n
      \n
    1. Dans l'agriculture, les DTU peuvent surveiller les niveaux d'eau, l'humidit\u00e9 et la temp\u00e9rature. Gr\u00e2ce \u00e0 diff\u00e9rents dispositifs intelligents de contr\u00f4le de l'environnement, elles peuvent contr\u00f4ler avec pr\u00e9cision les donn\u00e9es tout en recueillant des pr\u00e9visions de changements environnementaux externes par l'interm\u00e9diaire de plateformes en nuage et d'autres dispositifs externes. Ces syst\u00e8mes prennent des d\u00e9cisions concernant le contr\u00f4le des appareils en fonction de programmes sp\u00e9cifiques, ce qui permet de r\u00e9duire consid\u00e9rablement les co\u00fbts de main-d'\u0153uvre tout en diminuant le risque d'erreur humaine.<\/li>\n<\/ol>\n<\/div>\n
      \n
        \n
      1. Dans l'\u00e9conomie du partage, nouveau domaine de l'\u00e8re Internet contemporaine, les dispositifs DTU ont \u00e9t\u00e9 rapidement appliqu\u00e9s en raison de leur faible co\u00fbt, de leur technologie mature, de la pr\u00e9cision de leurs donn\u00e9es et de leur grande rapidit\u00e9 d'ex\u00e9cution. Les exemples incluent des fonctions dans les voitures partag\u00e9es telles que le d\u00e9marrage\/arr\u00eat du v\u00e9hicule, la facturation, la surveillance de l'emplacement, la pr\u00e9diction de la place de parking, le suivi du kilom\u00e9trage et le calcul des frais.<\/li>\n<\/ol>\n
