In the field of missile data acquisition in aerospace, in response to the problem that telemetry systems are influenced by environmental factors and and the "black barrier" existing in the detection area, an on-board telemetry acquisition and storage system that combines telemetry system and anti-destruction recorder is designed. The system is designed to ensure high impact resistance and stability through the design of the inner and outer protection structure of the anti-destructive recorder; in the hardware aspect, it realizes the functions of multi-channel high-voltage analog signal acquisition and digital signal reception by designing 56 channel analog signal conditioning circuit, analog-to-digital conversion circuit and optocoupler isolated interface circuit of multi-channel RS422 and LVDS digital signal; in the software aspect, it realizes the functions of multi-channel high-voltage analog signal acquisition and digital signal reception through the overall analysis of the system Logic design and telemetry module design, realize the data acquisition, storage, sending and reading. Finally, through the experimental test, it shows that the system can realize the function of multi-channel high voltage analog signal acquisition and data accurate and complete read back, and ensure the correctness and integrity of missile flight data.
