Virtual Fence IC Design

The goal of the project is to design a virtual fence system that keeps cattle in an enclosed area. The system consists of posts along the perimeter and low weight and power devices on the cattle that delivers high voltage stimulus if cattle are near the perimeter.

=Problem Definition= Now the current limitations are  Expensive, complex, and Bulky  GPS-based (not always reliable and energy hungry)Require getting the perimeter loaded onto eachdevice (intensive effort and/or requires internetconnection)  Strong/heavy energy source must be on animalMay cause stress on animals not knowing wherethe perimeter is  May require monthly subscription

Background
We used to use a barbed wire fence as a border to restrict the movement of cow. But the barbed wire cost is very high and not easy to move, it may injure animals, And requires regular maintenance. Also the rancher cannot check the position and status of the cow at any time. He must go to the farm on his own to see if the cow is out of range.

Deliverables
Permanent Beacons Know their own position  Geolocate Cows and Fence Line Mobile Beacons  Markers for Fence Line Nose Clip  Buzz  Zap  Long life User Interface  A user interface for the rancher

Specifications
Nanotron Devices  operates at 2.4 GHz (Zigbee)  3.3 V, 120 mA  Low Power Options

  

=Design Considerations= We are developing a simplified,low-cost approach to virtual fencing that leverages animal physiology and behavior, proximity beacons, and lightweight electronic nose clips to manage cattle distribution.
