After making the A/D mods, I finished checkout of the convertors and switches. Determined values for all of the fuses and got them installed. I have started on the software – got the initialization part written.Read more "5/28/17 Hardware Completed"
I’m using potentiometers and the A/D convertors to simulate flow control valves, turbine speed, generator loading, etc. Plus 5 volts on one side of the pot and GRD on the other side. Middle tap goes to the A/D card. Well… turns out there is a resistor voltage divider on the A/D card. Putting the pot […]Read more "5/24/17 Design Change"
Shout Outs! 1) Raspberry Pi – The core of my project. Definitely a solution looking for a problem. It has been rock solid. 2) AB Electronics UK – Supplied the I/O and A/D cards. Great Tech Support. 3) Express PCB – Their design software is very easy to use. Quick two day turnaround on the […]Read more "5/19/17 Shout Outs"
I used a number of articles to refresh my nuclear power plant operations memory. I would suggest reading some or all of the articles listed below. I found all of them on the internet. 1) The Westinghouse Pressurized Water Reactor Nuclear Power Plant (Westinghouse) This manual provides a complete description of a Westinghouse PWR. It […]Read more "5/18/17 Reactor / Plant Reference Material"
Finished wiring the lower Switch/Rotary panel. Remaining work for this panel is to wire the ribbon connectors and decode which I/O lines go to which switches.Read more "5/15/17 Wiring The Lower Panel"
The other part of the project is the graphics where current values are displayed. A mockup of the plant is shown. I’m using Zelle Graphics to display a GIF picture I created in Microsoft Publisher. I wrote a quick python program that would allow me to position/change text on the GIF picture until things lined […]Read more "5/11/17 Simulator Plant Graphics"
Here are the three circuit cards I had made. Express PCB has special prices for boards that conform to their 3.8 x 2.5 footprint. I was able to design the LED Driver and Status NOT Driver boards within the footprint. No way the Power Distribution Board would fit so I spaced it out so things […]Read more "5/10/17 Custom Circuit Cards"
