Smart Nurse Tank Concept Guide

Smart Nurse Tank Concept Guide

This user guide contains the workflow and progress of developing an integrated control system which is further embedded in an automated refill procedure from a nurse tank to a sectioned sprayer. The system enables the pumping liquid fertiliser product (Easy N) from the nurse tank into a section sprayer with automated start and stop once the sprayer was filled; allowing the operator to refill fast and safe without the need to exit the cab of the tractor. This report will cover the system developed currently and the goals for future integrations.
The specific architecture and features of the system can be described in three parts; the nurse tank trailer itself with pump and plumbing, the control system that manages the refill process once signalled to do so, and the remote monitoring system for the nurse tank level. The current method of refill is to fill the sprayer in a “top fill” manner through the top hatch via a hanging boom arm, rather than a docked and cam locked fitting.
The automated nurse trailer in this guide is flexible to any section sprayer which can be top filled via its hatch and has no requirements on the type of tractor or machine which is coupled with the sprayer implement. The report has two main sections: one covering the ‘v1’ prototype developed by UniSQ, and a proposal for a second version suited for commercial use based on the learnings from this project.
