摘要： Electric fences used to keep animals in or out of a particular area of land often cover great distances over all manner of terrain, making it very difficult to ensure the effectiveness of the entire length of the fence, especially at points distant from a human supervisor or at points which are not in a direct line of sight from a human supervisor. This invention relates to an electric fence monitoring system having a centrally located monitor and one or more remote units positioned along the fence, where the monitor uses wireless communication to broadcast a request for information related to one or more electrical conditions of the electric fence and the remote unit receives the request, takes a reading and uses wireless communication to broadcast a data message back to the monitor via wireless communication.
