[0002] Smart industrial gateways are intelligent industrial gateways that integrate edge computing. In addition to basic protocol conversion functions, they also have the following functions: they can actively collect and transmit data; they can parse data; they can filter and aggregate data; the new generation of smart industrial gateways focuses on data polymorphism, compatibility of various protocols, and edge processing of data. They are more convenient in deployment and operation, and their application scenarios and fields are becoming more and more extensive. However, the current smart industrial gateways cannot assist servers in edge computing, and their comprehensive capabilities are relatively weak. Summary of the invention

[0003] In view of the defects of the prior art, the present invention proposes an intelligent gateway device and an application method, which are implemented through the following technical solutions.

Assets use specific driver instances to communicate with underlying devices, and generic device resources are modeled as channels. Registers in a PLC or GATT characteristics in a Bluetooth device are examples of channels. In this way, each asset has multiple channels for reading data from or writing data to industrial devices.
