Embedded Agricultural GPS Navigation And Variable Fertilization Control Technology Research

With the development of information control technology, more and more areasof information control technology requirements gradually increased throughout thecourse of the study the proportion of information control technology is also growingin recent years, especially in the development of modern agriculture machinery veryquickly, in order to protect the production environment is not destroyed and polluted,to ensure economic maintain a virtuous cycle, resulting in a precision agriculture.Precision agriculture is an important form of modern agricultural productiondeveloped on the basis of modern information technology, biotechnology,engineering technology, consisting of a series on the latest high-tech. Advancedprecision agriculture at the more traditional agriculture is the application of globalpositioning system (GPS), geographic information technologies (GIS), remotesensing technology (RS), computer control technology, expert knowledge anddecision-making system, the positioning of agricultural production, quantitative,timing, do precision agriculture. Precision farming system is a highly integratedcomplex systems, is an important way to achieve low power consumption ofagriculture, efficient, high-quality, safe. Precision agriculture, including theimplementation of a number of aspects, such as GPS navigation driving, informationmanagement and decision-making based on GIS operations, and other variables,including navigation and variable assignment is an important part of theimplementation of precision agriculture.First, we propose a hardware embedded GPS navigation and variablefertilization of agricultural machinery control system components, according to theactual production hardware includes: Ag332GPS receiver, YC-ePC-A70s-W-typecar-touch computer, GPS navigation light and variable rate fertilization targetcontroller.Secondly, agricultural embedded GPS navigation and variable fertilizationcontrol of key technology software used by its key technology research and learning,applying it to implement software function, which can enhance the overall performance of the software to ensure the accuracy of the overall software reliabilityand continuity.Thirdly, is the implementation of software, embedded GPS navigation andvariable fertilization of agricultural machinery control system using GPS technology,GIS technology and embedded programming technology, agricultural embeddedGPS navigation and variable fertilization control system software installedYC-ePC-A70s-W-type car-touch computer, easy human-computer interaction.YC-ePC-A70s-W-type car-touch computer using simplified Chinese version ofWindows CE6.0R3as the operating system; using SQLCE as a database; using theC#programming language and eSuperMap controls, in the Microsoft Visual Studio2008software development environment based on the actual needs analysis,completion of the software.Finally, the hardware part and software parts together and build a completesystem for debugging and testing the system after using the system for comparativeanalysis of the test, the test results showed that: Agricultural embedded GPSnavigation and control system capable of variable fertilization meet the basic jobrequirements.
