plotting circuit network on power graph
Posted: Sun May 16, 2021 11:49 am
I've developed a method for displaying circuit network data on the power graph. The design uses sets of 1, 2, 4, 8 etc. lamps to draw an amount of power governed by the input signal. There is 1 lamp connected to the 'AND 1' circuit, 2 to the 'AND 2', 4 to the 'AND 4', etc. The power graph for the isolated power circuit plots the circuit value. To isolate the power grid I'm using a steam engine, so the thing requires steam input to run.
The first approach I tried was switching on and off various devices with power switches. The initial inrush of current to charge the device's internal battery causes a big spike in the graph. Logic gates have 1kW draw and a small internal battery, so make reasonable drains - the spike is small but still visible. Lamps have 5kW draw, but seem to have effectively zero internal battery, so the output on the graph is very clean. Switching power for lamps sometimes leads to power network partitioning issues where the graph will lose its history. Letting lamps turn themselves on and off using their own circuit network logic solves this problem.
There are 127 lamps, this is the effective resolution of the output trace on the power graph. You could increase it to 255 for more granularity.
In this example I'm graphing the fluid level of tanks as I pump water from one to the other.
