Abstract
An automated system for identifying a watering zone malfunction includes a sensor and a controller. The watering zone includes a valve that couples an input conduit to an output conduit. The output conduit terminates at one or more water distributors. The sensor is for capturing mechanical perturbations of the watering zone. The controller is configured to: store a profile defining at least one profile parameter based upon a transient operation of the zone in an intact state, receive the signal from the sensor during a watering operation when the zone is in an unknown state, compute a operation parameter based upon the signal for at least one time window of receiving the signal, determining a malfunction exists, and determine whether to take further action based upon the comparison.
