Abstract


UAV due to the lightweight and flexible characteristics , widely used in modern warfare detection . This paper discusses the the the UAV air data test system works , FPGA chip as the carrier demonstrate overall program suited to its characteristics , and focus on system -on-chip internal modular design are discussed . Divided according to the functions of each module in the design , based on the actual take , and design of the various modules of the test system . Air data parameters there is a lot of pressure altitude is a very important parameter to control the UAV normal flight , the UAV completed tasks . The common approach is to indirectly measure the UAV height by measuring atmospheric static pressure . The to of pressure altitude H_p the test system as the design of the main trunk , discusses the relationship between the system structure and each module test pressure altitude H_p . Hardware modeled after the completion of each module , using ASMD way , all modules using Verilog HDL source code written in modules to simulate and analyze the results through the preparation of the test stimulus file . The overall system is verified by simulation ; This article system is a real time system design needs . The pressure altitude measurement system in the front-end sensor frequency signal 5k to 10kHz, modify the corresponding register parameter word length and other precision measurements can be used in different frequency ranges . Using standard FPGA chip signal frequency , frequency measurement accuracy requirements are met , you can improve the speed of the test system . Compared MCU entire test system , the FPGA implementation has strong anti-interference , stable and reliable work .
