A virtual debugging system based on an OPC UA industrial communication protocol

Abstract

The invention discloses a virtual debugging system based on an OPC UA industrial communication protocol. Modules of the virtual debugging system are mainly divided into a data acquisition layer, a data interaction layer and a simulation equipment layer. The data acquisition layer comprises an industrial robot, a PLC and an OPC UA acquisition module; the data interaction layer comprises a data processing module, a Redis database module and an interaction interface module; the simulation equipment layer comprises a RoboDK simulation robot and a RoboDK simulation machining center; the data acquisition layer acquires output data of the PLC and the industrial robot through an OPC UA protocol, transmits the data as input to the data interaction layer, and writes the data transmitted by the datainteraction layer into equipment; the data interaction layer transmits data into the simulation equipment layer according to a data address configured by the interaction interface module and transmitsthe data of the simulation equipment layer to the data acquisition layer; the simulation equipment layer transmits data of the data interaction layer to the simulation model through an API, and transmits a signal of simulation equipment to the data interaction layer; and the system completes a virtual debugging function by controlling input and output of the simulation equipment.

Description

technical field [0001] The invention relates to a debugging system of various industrial equipment, in particular to a virtual debugging system based on the OPC UA industrial communication protocol. Background technique [0002] With the widespread use of industrial robots in various industries, industrial robots occupy an increasingly important position in the industrial manufacturing process, and the manufacturing system composed of industrial robots is quite professional, and improper operation will cause harm to the system, so Operators are required to have certain experience. "Virtual" refers to the use of simulation models instead of real equipment. "Debugging" is to make each device in the system run smoothly according to the program settings through tests. [0003] Most of the traditional virtual debugging systems are carried out on the simulation platform, all the equipment is virtual, so only the operator needs to operate on the software, and because all the virt...

AI Technical Summary

Problems solved by technology

[0006] First of all, the system can overcome the problem of communication security between industrial control systems and field communication equipment but cannot connect various types of equipment. Secondly, it also solves the problem of obtaining specified data in real time while consuming less computer resources. Finally, the OPC UA industrial The communication protocol is used in the virtual debugging system, which verifies the feasibility of the solution based on the OPCUA protocol in the large-scale manufacturing system
