Atmospheric Data Processing Experiment Management System Based On LABVIEW

Atmospheric data computer is the important airborne electronic equipment of airplane. It measures the static pressure, total pressure and total suffocated air temperature of the air stream through the airspeed head and total temperature sensor. And on that basis, to resolve flying height, lifting speed, true airspeed indicated airspeed ,mach number, and mach number rate. And then, send them to the cockpit displays system, flight control system, navigation system, etc. The quality of this system is not only closely related to the accurate detection of atmospheric data, but also affects the completion of tasks and the safety of the flight. But atmospheric data computer is packaged airborne electronic equipment. It is not convenient for learners and developers to understand and monitoring the entire process of data processing directly. So, it is very necessary to design a set of atmospheric data processing system based on PC for the relevant personnel.In this thesis, it is disscussed theoretically on the working principle of the system and atmospheric data decoding principle. It expounds the emergence reason of error sources and gives the corresponding processing method. Finally we verify the correctness of the calculation through the experiments. Combined with practical work, this thesis introduces the total design solution of atmospheric data processing system, and gives a detailed account of the parameters decoding realized by C language, methods of LabVIEW call C programs and the methods of design experiment management system through LabVIEW visual programming platform . It also introduces the process of LabVIEW communicates with SQL Server database and the application of network platform.The system saves all raw data and calculating data in database,and realizes the management of the database.The atmospheric data processing system can complete the supporting experiment of“aviation test system”It also can realize data analysis process quickly and achieve data management conveniently. The experimental results show that the experiment management system offers advantages of easy to use, good extensibility, better independent ability, low costs, etc. It can completely meet the demands of the course and has the aerospace characteristics.
