BOARD SYSTEM OF CONTROL AND REGCORDING OF FLIGHT INFORMATION Russian patent published in 2017 - IPC G01D9/00 

FIELD: physics, measurement equipment.

SUBSTANCE: invention refers to information-measuring engineering and can be used for flight data collection and recording, saving in case of air accidents, as well as for operational monitoring of aircraft systems and equipment. To do this, the system includes a protected onboard storage POS, a maintained protected onboard storage MPOS, an operational onboard storage OOS, saved onboard storage SOS; audio and video data acquisition unit AVDU, wherein each of the units: AVDU, POS, MPOS, OOS, is connected to the onboard aircraft computer network switch via AFDX bus; redundant power supplies RPS, which are connected to each system unit (except for SOS): POS, MPOS, OOS have one RPS unit, and AVDU unit has 3 RPS units; 2 video cameras connected to the AVDU unit, each of which is associated with it through one APINC 818 channel, a microphone that is connected to the VDU unit, and channels of multifunction indicators MFI are connected to the AVDU unit, at that, the AVDU unit output is connected to the SOS unit input, connected to the AVDU unit, the AVDU unit is associated with the MSOS unit, system units, including AVDU, are connected to the common power bus of the aircraft, at that the AVDU unit is connected to data inputs, alarm sensor, which is connected to each system unit and assigned to generate an "Alarm" signal.

EFFECT: invention provides expansion of system functionality by providing backup power, emergency frame transmission backup for flight information recording, monitoring of the aircraft systems information channel status with report development, increasing the inter-unit exchange bandwidth.
