Controls for your tracker mechanics

What a tracker controller has to do

• Sun position and backtracking for the row spacing of your plants
• Safety positions for wind, severe-weather warnings and snow – without internet, too
• Two drives per tracker in sync, limit switches, emergency stop
• Messages and data for operators and service

What Feldmelder does here

• The box computes the sun position and points the trackers; with backtracking it flattens the rows when the sun is low so that no row shades the next.
• The box works without the cloud – it decides on safety positions in the field and buffers its data for up to 72 hours.
• Wind stow from the wind sensor in the field; while it is active the box refuses the "automatic" command.
• On an official hail or storm warning of the German Weather Service (DWD) for the site the box moves the trackers to the safety position (off until it is set up).
• On a DWD snow or ice warning the trackers move to the snow position so that the snow slides off.
• If the link to a tracker drops, it follows its stored schedule and then moves to the safe position.
• A fault at one tracker reaches the portal with the tracker number; the other rows keep following the sun.
• Commands from the portal (safety position, automatic, maintenance) are signed and valid for two minutes only; the box rejects forged commands.
• The protocol between box and portal (TTP v1) is openly documented, with JSON schemas to validate every message.

How working together would start

We start with your documents: geometry, drives, sensors, power supply. From these we plan a pilot on one of your trackers – with acceptance criteria we agree on beforehand. Series and quantities come only after that.
