With the arrival of the Industry 4.0 era, intelligence and automation have become the keywords of industrial production. In this context, the importance of industrial intelligent gateway, as a key hub connecting industrial equipment and the Internet, is becoming more and more prominent. This paper will explore the function and role of industrial intelligent gateway and its position in the future development of industrial intelligence from a new perspective.
I. Definition and characteristics of industrial intelligent gateway
Industrial intelligent gateway, also known as industrial IoT intelligent gateway, is a kind of industrial-grade network equipment with the functions of data acquisition, protocol conversion, edge computing, remote management and so on. It is capable of connecting industrial devices with different communication protocols, standardizing and transmitting the collected data to the cloud platform or local server, and receiving control commands from the cloud to realize remote monitoring and management of the devices. Industrial smart gateway has the following characteristics:
Multi-protocol support: there are often multiple devices with different communication protocols in industrial sites, and industrial intelligent gateway can support access of devices with multiple protocols to realize unified data collection and transmission in heterogeneous networks.
Edge computing capability: The gateway's built-in edge computing capability allows for pre-processing of data at the data source, such as data filtering, aggregation, encryption, etc., which reduces the transmission of invalid data and lowers the network load, while improving data security and processing efficiency.
Remote management and control: with the help of cloud platform and mobile Internet technology, managers can check the status of the equipment, receive alarm information, and remotely control and adjust the parameters of the equipment anytime and anywhere through cell phones, computers and other terminals.
II. Functions and roles of industrial intelligent gateway
Industrial data collection: Industrial intelligent gateway can connect various PLCs, instruments, sensors and other industrial equipments to collect real-time running status of industrial equipments and various environmental parameters, such as temperature, humidity, pressure, etc., and send the collected data to the upper computer or cloud platform system in real time to realize remote monitoring and data analysis.
Industrial equipment control: Industrial intelligent gateway can connect various industrial control equipment, such as PLC, touch screen, DCS, etc., to realize remote control and automation operation, and improve the production efficiency of the factory.
Industrial equipment networking: Industrial intelligent gateway can realize wireless connection between multiple equipments in the factory, realize data exchange and linkage control between equipments, and realize intelligent management.
In addition, the industrial intelligent gateway also has strong security protection ability, using remote security communication method, combined with encryption algorithms to ensure communication security, strictly prevent data leakage. At the same time, it supports disconnection and reconnection, abnormal recovery, system self-monitoring and other functions to ensure that the equipment is online in real time to ensure the normal operation of the monitoring system.
With the continuous development of industrial Internet, 5G, Internet of Things and other new technologies, industrial intelligent gateway will be deeply integrated with cloud computing, big data, artificial intelligence and other technologies to promote the continuous improvement of industrial intelligence. The data collected through the industrial intelligent gateway can be analyzed by big data to provide enterprises with more accurate production scheduling, equipment maintenance and other decision-making support. At the same time, combined with artificial intelligence technology, intelligent diagnosis and predictive maintenance of equipment can be realized, further reducing production costs and improving production efficiency.
Industrial intelligent gateway, as the core hub of future industrial intelligence, will play an important role in promoting industrial transformation and upgrading, and enhancing industrial production efficiency. With the continuous progress of technology and the continuous expansion of application fields, the prospect of industrial intelligent gateway will be broader.
