Universal model abstraction system and method based on heterogeneous industrial data acquisition protocol

Abstract

The invention discloses a universal model abstraction system and method based on a heterogeneous industrial data acquisition protocol. The system comprises an industrial Internet of Things platform, an industrial gateway, a PLC and industrial equipment, the industrial Internet of Things platform comprises an equipment object model module, an industrial communication protocol model module, an object model and communication protocol mapping module and a data acquisition configuration publishing module; the equipment object model module is used for configuring an equipment object model based on industrial equipment and acquiring an object model instance of the industrial equipment; the industrial communication protocol model module is used for configuring an industrial communication protocol model and acquiring communication protocol parameters of industrial equipment; the object model and communication protocol mapping module is used for establishing dynamic mapping from an object model instance to a communication protocol parameter, namely obtaining data acquisition configuration; the data acquisition configuration issuing module is used for issuing data acquisition configuration to an industrial gateway of an edge end; and the industrial gateway is used for automatically receiving the data acquisition configuration and performing industrial data acquisition of related equipment based on the data acquisition configuration.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things of the Industrial Internet, in particular to a general model abstraction system and method based on a heterogeneous industrial data collection protocol. Background technique [0002] In the process of industrial production, equipment process data, environmental data, material and product data are continuously generated. These data are related to time series and reflect the entire life cycle of the production process of industrial products; the collection and fusion of these data is the basis for realizing intelligent manufacturing. [0003] The production data of industrial equipment is generally generated by the PLC (programmable logic controller) directly connected to the industrial equipment. According to the production status, there may be one or more PLCs in a factory area, and each PLC can be connected to multiple or multiple industrial devices. An industrial equipment may c...

Problems solved by technology

It caused trouble for subsequent data conversion, and even data incompatibility did not meet the requirements.

If you want to solve the incompatibility problem through manual configuration, you need to master the business layer model and the device layer protocol at the same time, and the development cost is high
