The invention belongs to the technical field of avionics, and particularly relates to a highly reliable micro-miniature airborne record system. The system comprises a central processing module (101), an ethernet receiving and dispatching module (104), an FPGA encryption and decryption module (103), a file management module (106), an NVPAM cache module (107) and an NAND storage module (108), wherein the central processing module (101) contains a main processor and an RAM. According to the micro-miniature airborne record system, an NVRAM is used for caching so that the situation can be avoided that an NAND medium is frequently written, accordingly the service life of the NAND medium is prolonged, cache data cannot be lost when the power fails, and meanwhile the system helps to rapidly destroy file data when emergency happens.
Description
technical field [0001] The invention relates to a data transmission and storage system, in particular to a miniature airborne recording system Background technique [0002] The airborne recording system is one of the key systems of the entire airborne avionics system, which undertakes the important task of data recording and transmission. Airborne data such as cockpit voice, waypoints and other data, the data volume is small, the on-board transmission rate is not high, but it is extremely critical and has high reliability requirements. The traditional miniature airborne recording system only has the ability to record data, and lacks the protection of data security and the ability to process data in emergencies (such as power failure, key destruction), or by adding large-capacity capacitors to maintain burst The power supply after power failure is used to realize power failure protection, which increases the complexity and cost of hardware design. Therefore, it is of great ...
