Just steering back a bit on topic, a little further progress today.
I was able to get the polling rates up significantly to get several updates per second.
I’m also now looking at monitoring/alerting. This first bit looks at how the F1 pump and system is performing.
This uses the pump relay state to measure two things:
1) Cycle time between pump activations. Too low of a time points to leakage/bleed off.
2) Pump on time. How long it takes the pump to raise the pressure from 40 bar to 50 bar. Again too long of a time here indicates a weak pump or heavy leakage.
3) Additionally I’ve added alerting to the clutch solenoid measure when they exceed 60cc/min.
The M3Stack has a small speaker so a alarm tone can be played.
With all these we can get some early warnings of failures or issues that need addressing.
Any other suggestions for monitoring?
