Design and Implementation of Control System for Deep-Sea Dry Recovery Unit Based on OPC UA

This paper designs and develops a control system based on the OPC UA for the requirements of the deep-sea dry recovery unit. In terms of hardware, the idea of decentralized collection and centralized control is adopted, with multiple IO modules arranged to collect device data. On the software side, establish the OPC UA information model and server to store the status data uploaded by the IO module, and send user instructions to the IO modules to generate a control signal output to devices. The user interface development was completed using QML language, based on the OPC UA client. Finally, the system functionality was verified through prototype testing.
