The key to intelligent manufacturing is to acquire and analyze big data, transform mass production data into adjustable and controllable information, and push the system to make judgments and decisions on its own. Due to the large number of machinery and equipment in the industrial production process involving hundreds of different data communication transmission protocols, industrial edge computing gateways are needed to optimize data collection and analysis to realize the transformation and upgrading to industrial IoT and intelligent manufacturing.
MQTT is a lightweight, simple, open, and convenient data transmission protocol. It has been widely used in communication sensors, smart homes, and miniaturized devices in multiple industries. MQTT has the following advantages:
●Open standard/interoperable (OASIS standard and Eclipse open standard (TAHU));
●Equipment and application separation;
●Event trigger report;
●Requires very little bandwidth;
●Transport layer security;
●Remotely initiate a connection (outbound only; no inbound firewall rules);
●Status awareness;
●Single source of data;
●Automatically identify tags;
●Data buffering (store and forward);
●Plug and play function.
In modern industrial manufacturing, only by mastering detailed data can we deeply analyze production defects and improve production efficiency. To increase the degree of data acquisition, in addition to expensive upgrades of advanced industrial equipment, old equipment can also be digitally and intensively transformed, connected to industrial edge computing gateways, and efficiently transmit production information through a standardized data transmission structure to achieve a limited cost Improve the overall perception and control of the entire production process.
The BMG700 edge computing gateway is developed by Baima Technology according to the typical application requirements of the Industrial Internet of Things and Ubiquitous Power Internet of Things. Support northbound protocols such as MQTT, JSON, HTTP, etc., and connect to various IoT platforms. It supports OPC, Modbus, TCP, UDP, some brand PLCs and other southbound protocols, extensive access, smart matching, powerful computing, 5G/4G wireless communication , and is an ideal choice for industrial Internet of Things.
