Abstract

The invention provides aeronautical data recording equipment. The aeronautical data recording equipment comprises a NAND-FLASH module, a first level conversion circuit, a second level conversion circuit and a third level conversion circuit, wherein a processing module is in bidirectional communication with the first level conversion circuit, the second level conversion circuit, the third level conversion circuit and the NAND-FLASH module and is used for receiving setting data and communication data, which are subjected to level conversion, and directly storing the setting data and the communication data into a memory in a direct memory access DMA manner; alternative storage of the data is realized by adopting a ping-pong caching manner and the data is completely written into the NAND-FLASH module; and an upper computer is communicated with the processing module and is used for setting working parameters of the processing module. The aeronautical data recording equipment has the characteristics of high-speed data transmission, high reliability and high interference resistance.

Description

technical field [0001] The invention relates to the technical field of aviation data storage and recording, in particular to an aviation data recording device. Background technique [0002] In foreign countries, from the end of the last century, it was first developed and developed on the solid-state data recorder for military use to today. The advantages of post-power storage data preservation, high integration, low power consumption and reasonable price also promote its application in many fields. [0003] The use of storage media includes static memory, dynamic memory and memory, etc., and its application fields are also expanding, from military applications to civilian fields, and in weapon systems, unmanned aerial vehicles, satellites, aviation, aerospace, deep sea There are also many applications in detection and so on. In addition, some recorder products under special and harsh environment requirements are also emerging. [0004] The defects of existing aviation ap...
