Abstract

An irrigation system comprises a plurality of towers, a time domain reflectometry (TDR) unit, and a central controller. Each tower includes a successive one of a plurality of safety switches, with each safety switch being either closed or open. The safety switch of each tower is electrically connected to at least one safety switch of another tower. The TDR unit is electrically connected to at least one safety switch and is configured to output data regarding an open safety switch. The central controller is configured to receive data from the TDR unit, and determine, according to the data from the TDR unit, at least one of a location of the open safety switch and an identifier of the tower associated with the open safety switch.
