| Yeah, I don't think I've seen a system that can currently effectively do a 'nozzle by nozzle variable rate that is changing based on prescription maps on a #-foot zone resolution'. You'd effectively need a PWM system (probably best) or a very complicated tiered nozzle cluster to be able to try pull that off. PWM would at least keep pressure more consistent than a nozzle cluster and keep things closer to what you'd want, but a nozzle cluster would be the only way you are getting a larger variance of like 0-40GPA variable rate across a prescription map.
There have been talks of having dual-solenoid PWM systems that'd effectively be able to use two solenoids and nozzles to replicate a huge rate range too (akin to having a tiered nozzle setup) that would probably do the best of both, but not sure where we are at for the processing power side of things. Systems seems to be able to work better with rate controllers over the last 10 years with PWM systems too, which would be right up there with the processing side of things. (as you could imagine swinging from high to low to no-flow areas on a VR map in extreme cases will be a tough ask for current rate controller tech as it can't react that quickly)
I'd be curious to see if Carbon-bee would be able to pull it off though, as maybe AI can anticipate look-ahead rates or stuff like that better than others to feed in a 'modulated flow rate requirement' to the rate controller so you can still keep a 'dumb' rate controller without it always being slow to react to huge swings in pressure and flow.
Pretty optimistic that we will see it eventually though. | |
