The Software Design And Implementation Of Digital Air Data Computer

With the development of Electronic Technology, the data air computer meetssoaring requirements, and it has entered the digital, integrated and rapid developmentperiod. DSP (Digital Signal Processor) is widely used in digital air computer for itsexcellent performance.The work principle of a digital air data computer is briefly analyzed in this article.Then, the air data computer error classification，compensation analysis and Functionsand the hardware part of the air data computer is introduced. Based on the above, theDSP design of air data computer is introduced in detail. This contains the design of theinterrupt program, the CDM configuration file and the main program.The purpose of testing, test methods, test results and performance are introduced intest section. The tests show that the measured values of the parameters can meet thedesign requirements. The implementation result of air data computer is accurate. This isconvenient for design and verification of the subsequent signal processing module.
