You can cater for non-crop and water sensitive areas under pivots through Variable Rate Irrigation (VRI). Avoid putting water where you don’t need or want it.The Farmscan 7000 system enables variable water application rates. Using GPS, banks of sprinklers are cycled on /off according to a pre-determined prescription map. Additionally, it controls pivot travel speed and end gun function for optimal efficiency.
The Farmscan 7000 master node can control five zones plus end gun in stand alone mode. By adding Farmscan's 7001 slave nodes along the boom on a simple shared communication system, up to 48 watering zones plus endgun can be controlled.
Sprinklers are grouped into banks and these banks are controlled by either an air or a water pilot line that turns the water off. Using air/water control greatly reduces sensitivity to impurities in the water.
Fail Safe Operation
This unique and innovative system is 100% failsafe. If the 7000 is disconnected from power, the pivot will return to normal operation, with all watering points on and end gun and pivot speed under normal manual control.
Prescription maps are created using PC desktop software. The application map divides the circular area covered by the pivot into 1-10° pie slices and every slice is divided into segments.
Rates can be assigned to as many or as few of these segments as required. Maps are then transferred to the 7000 controller via a USB stick. The GPS at the end of the pivot monitors actual position. If watering rates need to increase above 100%, the pivot will be slowed down. Similarly, if less than 100% is required in zones, the pivot will walk faster, saving energy and wear and tear.
All applications developed for the Farmscan 7000 are tested extensively in the field to ensure robust performance over many years. Products are under continuous development, with new and enhanced applications being released regularly.
