Description

The utility model relates to devices for monitoring flight parameters of an aircraft and can be used for video recording of emergency situations during the flight and analysis of such situations.

From the technical literature, an on-board drive is known (the so-called “black box”), which is protected and secured on board the aircraft (see “Encyclopedia of Aviation”, p. 118, ed. “TSB” and TsAGI, 1994). The on-board drive provides registration of flight information - parametric and speech. The parameters are recorded on magnetic or metal tape, which ensures the safety of information when exposed to high temperatures, shock loads, aggressive fluids, etc. This information is used by emergency commissions when investigating flight accidents.

The known device does not provide instant monitoring and recording of data at the current time by the ground recorder and storage of information not on board a flying aircraft, but at the ground control point of flights.

A known system for controlling flight parameters by a ground-based recorder (RF patent No. 2558167, IPC B64D 45/00, B64D 47/08, published July 27, 2015), including a smartphone, the lens of which provides an image of the dashboard on the smartphone screen, the position of command and control organs of the aircraft, as well as the position and action of the pilots, in addition, to record the voice information of the crew using a microphone microphone. Video and audio signals from a smartphone are transmitted via satellite, cellular mobile communication to a ground-based recorder, where video and audio recordings of flight parameters from take-off to aircraft landing are performed, then video and audio recordings of the ground-based recorder are used for technical analysis of flight results in case of emergency or aircraft search during off-aerodrome landing, as well as its disappearance from the radar screens of the ground-based air traffic control service.

The known system does not allow to fix possible external emergency situations with the aircraft, such as terrorist attacks, an explosion on board the aircraft, technical malfunction, lightning strike, a collision in the air with another object, an engine explosion, depressurization of the aircraft, and other factors that caused the destruction of the aircraft with its blackout .

The objective of the proposed utility model is to provide video recording of the emergency state of the aircraft and the transmission of visual information about the emergency in the ground recorder.

The technical result is an effective registration of the emergency state of the aircraft with saving a video image of such a situation and transmitting it to the ground-based recorder.

The problem is solved, and the technical result is achieved by the device for generating and transmitting to the ground recorder the video file of the emergency state of the aircraft installed in the upper part inside the keel of the aircraft, containing a video camera with a pupil and an ambient light sensor, an airplane emergency recognition module connected to it via a local area network, including a computing a device with a database implemented on it with pre-recorded descriptions or images of alarm situations, which connected through a hardware-software interface with a video camera, and the emergency state recognition module is adapted to analyze the signal from the video camera, with the ability to recognize the emergency state in accordance with a predetermined algorithm using the description of alarm situations stored in the database, and issuing a control signal to the associated with it, a module for generating and saving a video file of the last 10-60 seconds of flight, which is configured to continuously generate a video file of the last 1 0-60 seconds of flight and updating the specified video file with the frame rate of the video camera and connected to it by a local circuit, as well as connected to the module for transmitting the video file via satellite to the ground-based recorder, while the device contains an autonomous power source configured to recharge from the on-board network aircraft, and all elements of the device are located in an explosion-proof housing. According to the utility model:

- the aircraft emergency state recognition module is a computing device with a memory in which the program for recognizing the emergency state is recorded;

- the pupil of the video camera is placed in an explosion-proof transparent capsule and connected by a bus to the module for generating and saving the video file of the last 10-60 seconds of flight or performed together with it;

- the video camera is configured to generate a digital video signal in the normal or IF range depending on the illumination and the possibility of transmitting video images through local circuits to the aircraft emergency state recognition module, as well as to the video file generation and storage module for the last 10-60 seconds of flight;

- the database of the aircraft emergency recognition module contains individual databases for the description of emergency or alarm situations for each type of aircraft, for example, an explosion on board, an explosion near an aircraft, an engine ignition, a lightning strike, and a sudden blackout of the aircraft;

- an autonomous power source is made in the form of a battery with the possibility of constant recharging from the on-board network.

The device includes interconnected blocks electrically connected to each other according to rules known in the art.

The essence of the utility model is explained by the drawings, where:

in FIG. 1 shows a block diagram of the inventive device for generating and transmitting to the ground-based recorder the video file of the emergency state of the aircraft; in FIG. 2 shows the operation of the device in the event of an emergency on board the aircraft.

In FIG. 1 is indicated:

1 - Pupil of a video camera;

2 - Light sensor;

3 - Video camera;

4 - Aircraft emergency state recognition module;

5- Module for generating and saving the video file of the last 10-60 seconds of flight;

6 - Module for transmitting a video file via satellite communication to a ground-based recorder;

7 - Autonomous power supply with recharging from the aircraft network.

In FIG. 2: 8 - the claimed device, 9 - satellite, 10 - ground-based recorder.

The device operates as follows.

During the flight of the aircraft, the module 4 for recognizing the emergency state of the aircraft in accordance with a predetermined algorithm, using the description of the alarm situations stored in the database of the computing device, constantly analyzes the signals from the video camera 3 and, in case of recognition of the emergency state, transmits a control signal to the module 5 for generating and saving the video file last 10-60 seconds of flight. The latter is also associated with video camera 3, it constantly generates a video file with a delay of 10-60 seconds of flight and, in the absence of a control signal, is updated with the refresh rate of the video camera frame. In the case of a control signal from the emergency recognition module 4, it transfers the last stored video file lasting 10-60 seconds to the video transmission module 6 via satellite communication to the ground recorder and continues to generate and transmit the current video file of subsequent events until the device is damaged. Autonomous power supply 7 is constantly recharged from the on-board network, but in the event of a blackout of the aircraft, it will ensure the operation of the device (made in the form of a battery with the possibility of constant recharging from the on-board network).

Thus, the use of the device provides effective registration of the emergency state of the aircraft while maintaining a video image of such a situation and transmitting it to the ground recorder. The proposed system allows you to equip existing aircraft. It works on the principle of "set and forget." But in the event of the disappearance of the aircraft from the radar screens, it will give an answer what happened in the last seconds of the flight of the aircraft.
