g) User Registration Window On the registration window, the admin double clicking on the Expert System icon on the Desktop and splash up of the user access point window comprising of register and exit button. The system is design for the admin to grant access to the user before he/she can have access to the system. An evaluated and validated window result for a successful registration process of a New User (Field operator/Process Engineer) carried out by the admin is shown in Figure7 below: Figure 7: User Registration Window Admin Authorization Window: This comprises of the following textbox, Admin password and authorize button, the (field operator/Engineer) username, password, and login button. Retrieve your credentials Window: it also comprises of the text boxes, security question, security answer and retrieve now button. The above window interface also assist user with a forgotten login credentials, user (field operator/engineer) is expected to choose a security question and type the answer in the given text box and click the “Retrieve Now” button as shown in figure 6. h) The Main System Control Panel Interfaces The main control panel interface is where the users will navigate, monitor, controlled, and maintained the real-time conditions and readings (default parameters of the steam package boiler expert system with their operating setpoints for better efficiency, reliability, performance, and product throughput. The main control panel interface comprises of seven (7) panels as shown on Fig7. above. • The Top Control Panel • The Drum Water Quality Display Panel • The Feed Water Quality Display Panel • The Level, Temperature, Flow and Pressure Bars • The Steam Package Drum • The Bottom Control Panel Each of these operational panels are describe below for better understanding. The top control panel: This is menu situated on top of the main application comprises of simple “automatic and manual sim” buttons”, “setting” button, panel selection drops down menu bar and “logout” button. The automatic simulation button is used to run and navigate the steam package boiler in an Auto Mode where all errors are corrected by the designed fuzzy logic system. The Drum Water Quality Display Panel: This drum panel on the main application displays the real-time parameter values of the Total Hardness as CaCO3 in ppm, TI (ppm Fe), TC (ppm Cu), Oil & Organic, pH value at 25 Deg. C, total dissolved solids (ppm TDS), and the Reactive Silica max (ppm SiO2) of the water in the boiler drum, in their respective range of values.
