Improvements and upgrades to the universal water system's communications, operations, and controls

Anthony Moody

This report details the improvements and upgrades to Murdoch University’s Universal Water Systems (UWS) operations, communications and controls. The UWS can operate as a single integrated control system or as three smaller sub-systems through the manipulation of manual valves. A high level of system interaction is present, which allows the use of single-input-single-output (SISO) or multiple-input-multiple-output (MIMO) operation, giving students the opportunity to implement various styles of control strategies. This project has focused on improving hardware, Client Software, Master Software, documentation, and the development of Student Software and an automatic operating procedure. Faulty equipment was replaced to ensure the system could perform optimally, as the hardware governed all possible system actions. The Client Software was modified to meet abnormal situation management (ASM) compliance and ensure operators have system-wide control. Further development of the Master Software has allowed an implementation of an automated operating procedure, which can demonstrate the capabilities of the system in a visually spectacular way. The Student Software was developed to create a workspace in which students can customise the user interface as well as design and implement advanced control schemes into the system, with no effect on the underlying system code. The project is now complete, with successful testing and commissioning on all aspects of the UWS. The changes have been thoroughly documented with extensive user and maintenance guides developed. There is still room to improve the UWS; however, these improvements were beyond the scope of this project. At the completion of this project, the system now allows students complete and reliable operation of the UWS through the use of a standardised interface and a fully customisable workspace.
