My brother's girlfriend had gotten an RV bus and I was asked about updating the controls. I looked into this and started writing a program to control and monitor things like thru water pump, water heater, generator start/stop, inverter on/off, battery voltage, battery amperage, battery level and tank levels.
I got these things to work on the test bench and started working on WiFi access to the plc. WiFi access from any given spot was going to require more hardware so, I dropped that for now.
My brother (Jeff) and his girlfriend (Julie) had taken a vacation to the Grand Canyon. So, I did not get the chance to get anything installed. That gave me time to think about what else could be incorporated into this control system. That's when I thought about and auto-leveling control for the leveling jacks. I ordered some parts and made a leveling sensor plate to be mounted under the bus. I then got started on the programming. After finishing the program, they got back from vacation and decided to move to California. So, still no time to get the system installed. Over the next several weeks, I debugged and studied ways to refine the whole plc code.
I have been thinking of incorporating the environmental thermostat controls. Maybe even main engine and generator temps. Maybe I'll do it after the rest of the system is installed and fine tuned.
Stay tuned...
