Miniature caching recorder for civil aviation

Abstract

The invention belongs to the technical field of avionics and relates to a miniature caching recorder for civil aviation. The miniature caching recorder comprises a case part, an aviation connector, a data management module and a battery, wherein the aviation connector is mounted at the physical center of the back of the case part, is used for being connected with aircraft equipment and plays a structural support role; the data management module and the battery are mounted in the case part, and the data management module is connected with the aviation connector. The miniature caching recorder has the advantages that the miniature caching recorder is connected with a universal computer through a USB interface, the miniature caching recorder can become a removable storage medium, and accordingly direct data reading is achieved; the battery is designed in the miniature caching recorder, and the battery can supply power for the miniature caching recorder when external power supply fails; the ARINC-717 and ARINC-429 interfaces used by the miniature caching recorder are directly connected with an ARM microprocessor through a SPI interface, an situation that originally the ARINC-717 and ARINC-429 interfaces can only be connected with the ARM microprocessor through FPGA is changed, part module volume is reduced, and circuit design is simplified.

Description

technical field [0001] The invention belongs to the technical field of avionics and relates to a miniature civil aviation cache recorder. Background technique [0002] The cache recorder is used to record flight data. It can quickly and conveniently obtain flight data and shorten aircraft maintenance time by quickly replacing the storage medium in the product. It is widely used in the daily maintenance of aircraft. In the previous cache recorder design, the product size was large and the weight was heavy. In light and small aircraft, because the aircraft is small and the take-off weight is light, the airborne equipment required must be small in size, light in weight, and reliable. High and low cost, so the traditional cache recorder has been unable to meet the use requirements of light and small aircraft, and a miniature cache recorder must be developed to meet the use requirements of light and small aircraft.

Problems solved by technology

In the previous cache recorder design, the product size was large and the weight was heavy. In light and small aircraft, because the aircraft is small and the take-off weight is light, the airborne equipment required must be small in size, light in weight, and reliable. High and low cost, so the traditional cache recorder is no longer suitable for the use of light and small aircraft, it is necessary to develop a miniature cache recorder to meet the use requirements of light and small aircraft
