Embodiment approach 1

[0042] Implementation Mode 1, see figure 1 This embodiment will be described. The MOM system automation equipment data interaction integration platform based on the OPC UA protocol described in this embodiment, its upper layer is Kafka and MySQL cluster, the middle layer uses OPC UAClient to build the architecture, and the bottom layer uses KepServerEX to build the OPC UA server.

[0043] In this embodiment, the Kafka and MySQL clusters in the upper layer are used to realize data collection and storage, and form data interaction with the OPC UA Client in the middle layer;

[0044]In this embodiment, the OPC UA Client in the middle layer realizes data interaction with several PLC devices through the KepServerEX in the bottom layer.

[0045] The data interaction between KepServerEX and the application is realized through the OPC protocol.

[0046] The platform described in this embodiment communicates with PLC equipment through KepServerEX, and the application program connects...

Embodiment approach 2

[0065] Embodiment 2. This embodiment is a data interaction method corresponding to the MOM system automation equipment data interaction integration platform based on the OPC UA protocol described in Embodiment 1. The method is as follows: the MOM system communicates with the MOM system through Kafka and MySQL clusters. The OPC UA Client realizes data interaction; the OPC UA Client realizes data interaction with several PLC devices through KepServerEX.

[0066] In the method, the OPC UA Client realizes connecting two OPC servers on the same network through VPN or the Internet through the OPC UA Client Driver, and creates a tunnel between the two OPC servers.

[0067] The Kafka is used to receive messages from the database and all applications into corresponding topics, and then import them into the MySQL database; the data stored in the MySQL database can be directly read by the MOM system.

[0068] The data interaction between KepServerEX and the application is realized throug...

Abstract

The invention discloses an MOM system automation equipment data interaction integration platform and method based on an OPC UA protocol, and relates to the technical field of industrial intelligent manufacturing. The problems that in an existing MOM system, communication protocol standards of field devices are inconsistent, and message blockage is likely to occur in the real-time data communication process are solved. According to the MOM system automation equipment data interaction integration platform based on the OPC UA protocol, the upper layer is a Kafka and MySQL cluster, the middle layer adopts an OPC UA Client to build a framework, and the bottom layer adopts a KepServerEX to build an OPC UA server. The data interaction between the KepServerEX and the application program is realized through an OPC (OLE for Process Control) protocol. The platform is communicated with the PLC equipment through the KepServerEX, and the application program is connected with the KepServerEX through an OPC (OLE for Process Control) protocol. According to the OPC UA Client, an OPC UA Client Driver is adopted, so that two OPC servers on the same network are connected through a VPN (Virtual Private Network) or the Internet, and a tunnel is created between the two OPC servers. The system has a unified framework, is an open platform, is high in expandability, and is suitable for the field of industrial intelligent manufacturing.

Description

technical field [0001] The invention relates to the technical field of industrial intelligent manufacturing. Background technique [0002] The definition of manufacturing operation management in the IEC / ISO 62264 standard is: the activity of transforming raw materials or parts into products by coordinating and managing resources such as personnel, equipment, materials and energy of the enterprise. It includes managing those activities performed by physical equipment, people, and information systems, and covers activities related to scheduling, capacity, product definitions, historical information, plant information, and related resource status information. [0003] MOM (Manufacturing Operation Management) manufacturing operation management system is to delineate the boundary of manufacturing operation management in a broader sense, as a general research object and content in this field, and construct a general activity model for the four main categories of production, mainte...
