A wireless interface remote monitoring system for self-propelled irrigation systems (center pivot and lateral move sprinklers) includes a remote terminal unit (RTU) mounted on an outer drive tower of the irrigation system. The RTU includes a radio transceiver capable of sending and receiving data packets over a satellite or terrestrial telemetry backbone to and from a central control computer. The RTU further includes a current sensor and a GPS receiver both for detecting movement or non-movement of the sprinkler, a microprocessor with nonvolatile memory for storing current data and GPS coordinate data from readings taken in series over time, and a pressure or flow sensor for detecting the presence or absence of water flow at the outer drive tower of the sprinkler. The current sensor connected between the RTU and a tower drive motor, allows the RTU to calculate the “movement” or “non-movement” of the irrigation system over a specified time period. Redundantly, the GPS receiver records changes in position to indicate movement or non-movement within the GPS error tolerance. Once a change from movement to non-movement or vice-versa is determined, the RTU transmits the data by satellite or radio telemetry to a central control computer which logs the movement or non-movement of the monitored drive tower, the GPS coordinate data and the water status readings, all with time and date stamp. The central control computer creates “page message” and “text message” updates as necessary on the status of individual irrigation systems and “groups” of irrigation systems that are in turn delivered to wireless devices and computers for sprinkler operators.
