Problems solved by technology

However, existing domestic data recording devices generally use digital interfaces such as RS-485, USB2.0 or 100M Ethernet and a single serial bus for data reception and storage array writing, and the storage rate is low. At the same time, the traditional structure The design is also becoming more and more difficult to ensure the reliability of the storage body after the aircraft crashes to the ground at high speed
