Abstract

The present invention relates to an OPC UA data service gateway device and an implementation method thereof. The method and device are used for realizing an embedded OPC UA server in the condition of applying industry-standard communication protocol OPC UA, the related information data of different types of field equipment such as an instrument and a PLC can be collected periodically, the equipment is mapped to an OPC UA address space, corresponding equipment model and equipment relation model are established, and the identification and management of the field equipment are realized. At the same time, in order to achieve the interaction between an OPC UA client and the server, an OPC UA transaction management mechanism is applied, and thus the OPC UA server can provide monitoring, listening, inquiring and other services for the client. The invention aims to use an OPC UA protocol to realize an equipment interface technique with the support of multiple wireless communication protocol standards, service adapter hardware with low power consumption and easy expansion is used as a carrier, and thus the underlying protocol and implementation are not considered in carrying out automatic control.

Description

technical field [0001] The invention relates to an OPCUA data service gateway, in particular to an OPCUA data service gateway device and an implementation method thereof, which are used to design an embedded service adapter according to the standard protocol OPCUA. Background technique [0002] With the rapid development of today's industry, the continuous improvement of production efficiency requirements, and the rapid development and integration of control technology, information technology and network technology, the demand for data collection and long-distance transmission in different industrial fields is also increasing. Due to the large number of manufacturers of industrial equipment, the data formats and types generated by the equipment produced by different manufacturers and applied in different industrial occasions are also very different. Most of the existing data gateways complete data acquisition through bus technologies such as RS485 / CAN / ModBus, and only suppor...
