Design Of Control Software For Meteorological Radar Terminal System Based On Loongson

Terminal system is an important part of weather radar,which is composed of various application software running on computer.It mainly completes radar system control,fault detection,automatic calibration,data acquisition,data storage,data processing,meteorological product production and display,etc.At present,the terminal systems of domestic meteorological radar are mostly based on Windows and Intel CPU platforms,which have great potential information security risks and uncontrolled information security.In this case,we have carried out the research of weather radar terminal system based on domestic CPU and domestic operating system.The main work of this paper is to study the development and design of real-time control software for meteorological radar terminal system under the environment of Loongson CPU and Kirin Operating System.This paper introduces the composition and working principle of meteorological radar,and designs the overall structure of the real-time control software of terminal system.The software adopts the server/client structure,takes monitoring and acquisition as the server side,and real-time display software as the client side,and divides its functional modules.In order to solve the actual situation of low main frequency of domestic CPU,the software mainly adopts modularization and multi-threading design method,and designs modules of data acquisition,sky-control threads,state monitoring,radar control,radar testing,image display and data storage.The modules are integrated to realize Loongson CPU and winning Kirin operation.The functions of data acquisition and storage,system monitoring,image processing,data distribution and sharing of the real-time control software of meteorological radar terminal system under the system platform are implemented.The validation test in real environment is carried out on the whole radar,and the test results meet the design requirements.The project succeeds in research and development,and achieves completely autonomous,controllable and safe meteorological radar terminal products.It gradually replaces the existing real-time control software of meteorological radar terminal system based on Intel CPU and Microsoft Windows operating system,eliminates the information security hidden dangers existing in the information processing and exchange process due to the use of imported equipment and chips,and realizes the real-time control of meteorological radar terminal system.The whole process of software development,production,upgrade and maintenance can be controlled independently.
