Description

The proposed utility model relates to the field of aviation instrumentation, namely to systems for recording parametric (flight) information and can be used to collect, register and save flight information necessary to investigate the causes of a flight accident or its premises, as well as the operational use of information for assessment crew actions during flight or operational control.

Known static storage device according to the patent of the Russian Federation No. 2024923 class. G06F 3/06, which is a solid state drive containing a computer bus, an address port, a data port, control ports, an address decoder, power decoders, a memory unit, and key blocks. In this case, the external computer bus, address, data and control ports, as well as the address decoder, perform the function of the internal micro-computer of the device, and the power supply is represented by two power buses.

The KARAT-B on-board flight information monitoring and recording system is also known (www.qosniias.ru/paqes/karat/n_reklama 1.htm)

This system contains a flight information collection unit, a control panel, sensors, an on-board protected drive.

The flight information collection unit is intended for operational monitoring of the object, as well as transferring the results of control to the information display system and for documentation in the on-board secure storage device, as well as organizing verification of on-board equipment during operational types of technical maintenance of the object.

The known system collects, processes and records parametric and sound information from aircraft sensors and airborne systems, overwrites the recorded parametric and sound information to the ground system for its further processing and analysis, as well as stores and protects recorded information in the event of an accident.

However, in the known system, the presence of difficulties in operation can lead, ultimately, to a decrease in flight safety.

The task to which the claimed utility model is aimed is to increase flight safety by identifying (fixing) system failures and providing information about the conditions of failure occurrence, as well as advanced training and discipline of the crew.

The technical result of the utility model is to provide an assessment of the crew’s actions for controlling the aircraft, meeting the restrictions and recommended flight modes defined by the flight operation manual (flight operation manual), the correct use of aircraft systems and equipment, evaluating the functioning of a number of aircraft systems, which ultimately increases safety flight.

The problem is achieved in that in the registration system of parametric (flight) information containing a flight information collection unit, electrically connected to sensors, a control panel, as well as an instrument speed indicator, protected by an on-board drive, electrically connected to a control panel, according to a utility model, digital the flight information collection unit is electrically connected to the installed operational flight information storage device, which is connected to the control panel.

Thus, the presence of an installed operational drive provides quick and convenient removal of registered information. The digital form of recording provides high accuracy of information registration (0.5-1%), a large amount of registration parameters. Information storages store information for a long time (for the last 25 hours).

The essence of the utility model is illustrated in the drawing, where figure 1 shows the structural diagram of the system.

The system for recording parametric (flight) information comprises a digital block 1 for collecting flight information located on the cushioning frame, electrically connected to sensors and systems of the aircraft, as well as to the control panel 2. The digital block for collecting flight information is also connected to the on-board protected drive 3, electrically connected to a speed indicator 4 and an operational on-board drive 5, also associated with the control panel 2.

The flight information collection unit receives, converts analog, analog-discrete (frequency) and discrete (one-time commands) signals and generates information for registration, and provides programmable reception of information, reception and conversion of service information, reception from the control panel and recording of identification values into the frame data.

The control panel is designed to enter and display service information, manually turn on the system, and indicate failure. The identification data (time, date, flight, centering, take-off weight) is entered manually using the buttons located on the front panel of the control panel. The entered data from the decimal number system is converted to binary decimal and entered into the flight information collection unit, where they are distributed among the frame positions.

The operational drive provides reception from the flight information collection unit to two independent inputs in the form of a bipolar addressless serial code with a return to zero and recording of the received information in the form of files on a memory card.

The protected on-board drive is intended for the accumulation of parametric information in flight and its preservation in the event of a flight accident. A secure on-board drive accepts input information received in the form of a two-frequency serial code and writes it to a secure memory module integrated in a secure on-board drive, also records and stores information for the last 25 hours of operation, reproduces recorded information, and provides the ability to copy recorded information on board aircraft in a personal computer, saves information regardless of the availability of power.

On the plane, the system can be manually turned on using the switch on the control panel, as well as automatic if the system is not manually turned on by the crew before the flight.

For automatic inclusion in the system, a speed indicator (air relay) has been introduced, which is activated at an aircraft speed of ≈70 km / h. and gives a signal to turn on the system and connect to it an emergency power source - the battery.

The use of a signal from the speed signaling device in the power circuit of the system does not allow the system to shut down the system in flight by the crew at their workplaces in case of erroneous actions.

The proposed system converts the signals received from the standard on-board equipment of the aircraft (systems and sensors) into a digital code with their subsequent registration in the solid-state memory module of the protected on-board drive and the memory card of the operational drive. The power source of the system is an on-board DC voltage network of 27V. In case of failure of the main power supply, emergency power is provided. Switching to emergency power is automatic.
