Abstract

The invention discloses a general aircraft data recording unit, belongs to the technical field of flight data recording, and aims to solve the problem that the existing data recording unit is not suitable for small aircrafts such as general aviation due to the defects of single type of acquired information, low integration level, simple communication interface and non-universality. The system comprises an MCU logic processing unit, and the MCU logic processing unit is electrically connected with a data storage unit, a data export interface, an RS232 data recording interface, an angle displacement acquisition interface, a temperature acquisition interface, a flap position recording unit, a stall alarm recording unit and an elevator joystick force recording unit. The RS232 data recording interface is electrically connected with an airborne RS232 communication bus, the stall alarm recording unit is electrically connected with a stall alarm detection system, the flap position recording unit records the position of a flap, and the elevator joystick force recording unit is electrically connected with a force sensor. The method is suitable for a general aircraft data recording unit.

Description

technical field [0001] The invention belongs to the technical field of flight data recording, in particular to a general aircraft data recording unit. Background technique [0002] The existing flight parameter recording system is an onboard electronic device used to record various system parameters on the aircraft, commonly known as "black box". The recorded flight parameters can be used for fault recording, ground maintenance, aircraft daily flight quality assessment, aircraft status analysis and flight. accident analysis. [0003] The existing data recording units generally have shortcomings such as single type of collected information, low integration, simple and uncommon communication interfaces, and are not suitable for small aircraft such as general aviation. With the development of the general aviation industry, general aircraft have the characteristics of large demand, flexible application, high integration, light weight and low cost. The development of data record...
