Agricultural Irrigation Systems Advantages Maximum Flexibility: allows distribution of the parcels in a larger number of plots and turns, which can be easily matched with soil and crops characteristics Increase Productivity: will achieve maximum uniformity of water and fertilizer distribution, which results in better and more equal yields Savings in operation: reduce the water and other supplies consumption It is also possible to reduce the travel of the tractors, making the grouping of irrigation turns in response to the geography of the land Time Saving and avoid manual work: permitto program the irrigation frequency and characteristics and then be executed by the system Division into lots of an agricultural field Scalable Solutions: permit to work with different sizes of irrigation systems in a modular way, allowing reuse code and finding the right equipment for your need Overview Solution Automatic Irrigation Systems appears from the need to optimize the use of water and other resources on agricultural crops Using automatic devices ensures that plantations receive the necessary amounts of water and nutrients at the right time and according to climatic and geographical conditions There are a number of alternatives for Rockwell Automation to control these irrigation systems From simple architectures based on Micro800 or MicroLogix until CompactLogix,based ones, depending on the complexity of the system design (signal number, irrigation turns, type of pump start) Additionally it is possible to monitor the conditions of each system component and to maintain the normal operation and service The components of an automated irrigation system are commonly: Filtering System Fertilization System Drip Hoses and Accessories Field Valves and Accessories Acidification System Pipes Pump System The Logix Control Platform from Rockwell is the basis for developing a control, display, information and communication robust system The design and delivery process is more efficient and lower cost Unlike conventional control architectures, offering fully integrated solutions, using a single scalable control platform and a single development environment, you have different options for communication, and allow optimal reusing engineering designs and coding Agricultural Irrigation Systems Modular Programming and Reusable Pressure Sensors With modular programming we refer to a number of conventions and best practices on industry standards, followed in developing code that will allow us to make changes to the irrigation control system functionality without rewriting the code The pressure measurement is an important factor for the normal operation of these systems The pressure control ensures the proper functioning of the pumping equipment (including auxiliary systems, cleaning and lubrication), as the precise distribution of water and fertilizer dosage Among these we have the choice of tags, implementation of state models, predefined HMI screens, etc For this specific application we offer available pre-configured modules for management of: Pressures: performs reception and analog signal processing (scaling, alarma levels, etc.) It is used in all the pressure measurements, either for irrigation, pumping and condition monitoring Pressure Control: Performs PID pressure control loops in the system, allowing easy change of parameters, benchmarks and alarm mode Rockwell Automation has used 836E sensors for this technical alternative, whose main characteristics are: Operating pressures ranges: from -15 to 6000 psi (gauge) Outputs: Independently programmable dual PNP NO/NC outputs or 20 mA analog output with single PNP NO/NC Housing: Rugged, corrosion-resistant 316LStainless steel housing with IP66 rating enclosure Optional Display: Four-digit 14-segment digital display SensingElement: 316L Stainless steel Selectable units of measurement: kPa, psi, bar, or % Turns: allows automatic handling of the irrigation It is able to control the start and stop of the pumping equipment according to the schedule entered by the operator and monitoring conditions 836E Sensors Agricultural Irrigation Systems Automated Irrigation Systems TypicalArchitectures Flex I/O PanelView Component PanelViewPlus Flex I/O Micrologix Micro830 Point I/O PowerFlex 70 PowerFlex 40 Pump Motor Pump Motor Based on MicroLogix Based on Micro800 CompactLogix Armor Point I/O PanelViewPlus Pump Motor PowerFlex755 Publication WWW-AT-001-A-EN-P – May 2013 Copyright ©2013 Rockwell Automation, Inc All Rights Reserved Basedon Compact Logix
