Description

A kind of flying quality and audio collection register

Technical field

The utility model belongs to the avionics field, relates to a kind of flying quality and audio collection register.

Background technology

Flight data recording system, be commonly called as " black box ", generally formed by flying quality collector (Flight Data acquire unit is called for short FDAU) and flight data recorder (Flight Data Recorder is called for short FDR) with anti-crash ability, the flight data recording system recorded data, significant for air-accident investigation.Passenger cabin voice-frequency sender (Cockpit Voice Recorder is called for short CVR) then be gather, the register with anti-crash ability of logging machine group membership conversation, passenger cabin audio-frequency information, the information that the passenger cabin voice-frequency sender records, in conjunction with the flying quality that flight data recording system records, passenger cabin sight and Aircraft State when the aircraft accident of can reducing more clear, really occurs.For light-small aircraft, because its cost control is strict, the body limited space is suitable for FDAU, the FDR of large aircraft and price and the volume of CVR, is unacceptable for baby plane.So develop a kind of light-small aircraft that is suitable for, small volume, collection flying quality and audio data collecting, the flying quality that is recorded in one and voice-frequency sender be necessary.

Summary of the invention

Technical problem to be solved in the utility model: the utility model provides little, comprehensive, low-cost, the safe and reliable flying quality of a kind of volume and audio collection register for the flight data recording system that is installed on civilian light-small aircraft.

The technical solution of the utility model: a kind of flying quality and audio collection register comprise power circuit 1, switch and frequency signal Acquisition Circuit 2, analogue signal acquisition circuit 3, integrated data management circuit 4 and data storage circuitry 5;

Described analogue signal acquisition circuit 3 includes the signal receiving circuit 31 that is comprised of front end modulate circuit 301 and multiway analog switch 302 that gathers control module 30 and some groups of parallel connections, is used for receiving simulating signal, interchange rate signal and synchronizer signal;

Described integrated data management circuit 4 links to each other with data storage circuitry 5 by pseudo-parallel bus 41, is used for the record of flying quality and voice data; Fpga chip 42 in the integrated data management circuit 4 is connected with Front Side Bus equipment and sound signal, realizes the collection to bus signals and sound signal.

Ethernet 43 in the described integrated data management circuit 4 is connected with service equipment, is used for loading and the maintenance of program.

MAX232 chip 44 in the described integrated data management circuit 4 links to each other with development equipment by RS-232 interface 45, is used for debugging and exploitation.

The beneficial effects of the utility model: the utility model flying quality and audio collection register, can be simultaneously to flying quality and sound signal gathers and record, cost is lower, safe and reliable, greatly reduced to fly to join the volume and weight of system, on the light-small aircraft of the interior limited space of the machine that is installed in of being more convenient for.The utility model uses Ethernet to safeguard, the user uses general portable computer, can carry out that data are downloaded, the type plane No. is inserted, equipment Inspection, device program are upgraded, the detection maintenance work of relevant device, sensor on the aircraft, the maintenance cost of greatly having saved the user.
