GTR MQTT gateway actively collects device data and performs protocol analysis. After the parsed data is standardized, the MQTT protocol is used as the uplink access protocol. Through the corresponding topics on the message publishing server, the user-developed software system is used. The cloud platform acquires data by subscribing to the topic of the message. When the software system/cloud platform sends instructions or writes data to the device, the application software system/cloud platform issues a message to the corresponding gateway, and then the gateway transfers the data to the device; thus implementing the software system/cloud platform and site Equipment data reporting and control. 1, purchase a Wutong Bolian MQTT gateway If you use 4G or 3G Internet access, you need to purchase an IoT card (you can contact Itobo Link IoT card sales engineer or directly to the operator to purchase) 2. Build the MQTT server by yourself and develop the software system and build the cloud platform according to the document. 3. If you have a budget for funds, you can directly purchase the Botong Cloud Data Cloud platform and then quickly develop it through the Restful API. Wutong Bolian offers two development methods: (1) The user purchases the Bolink MQTT gateway and directly connects with the independently developed cloud platform. The user sets up the MQTT server and develops its own cloud platform. Among them, Wutong Bolian MQTT gateway can realize data collection, analysis and standardization for various field devices and upload them to the cloud platform. (II) The user purchases the Bolink MQTT gateway and the Wutong WIOT-DCloud Internet of Things data cloud platform, and directly develops the cloud platform system directly through the Restful API; in which the Wutong-Wuhan-Connected WIOT-DCloud Internet of Things data cloud platform provides optimization. The MQTT server function, providing engineering configuration and device management functions, providing timing database and relational database, users only need to directly obtain data through the HTTP API interface for data analysis and data display.
