Remote current sensor monitoring system and GPS tracking system and method for mechanized irrigation systems

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.

Irrigation controller water management with temperature budgeting

ActiveUS7266428B2Easy and less-expensive to installEasy and less-expensive to and and maintainSelf-acting watering devicesClimate change adaptationAgricultural engineeringControl theory
The present invention provides methods for water conservation with AC, DC, or ambient light powered irrigation controllers without the use of complex ET (evapotranspiration) data or ET related service fees. Programming may consist of the operator entering a preliminary irrigation schedule, and entering the local zip code. The controller then periodically calculates a water budget by comparing current (non ET) local geo-environmental data with stored local geo-environmental data, and then modifies the preliminary schedule using the water budget. A number of embodiments are possible: stand-alone controllers with a temperature sensor attached directly to the microprocessor within that controller, or as a centrally placed CBM (Central Broadcast Module) which calculates a water budget percentage which is transmitted to one or more field controllers by wired or wireless means. Alternately, a TBM (Temperature Budget Module) that is separate from the controller is connected between the controller outputs and the valves, or mounted at the valves themselves. The TBM periodically calculates the ,water budget, monitors the controller outputs and adjusts the irrigation schedule based upon the water budget ratio. Because of its flexible capabilities with AC, DC, solar, or ambient light powered controllers, as a centrally broadcast water budget ratio in a wired or wireless configuration, or as an add-on to existing controllers or valves, its programming simplicity and close approximation to ET without its complications and cost, the present invention has the potential to save more water and minimize runoff than currently available ET methods.
