Description

The invention relates to information-measuring equipment and can be used in on-board systems for recording information generated by systems and units of controlled vehicles, both on small and large aircraft.

A known data recording system comprising an information collection and processing unit, an operational on-board drive, a secure on-board drive, an additional on-board drive, a video information processing unit (patent RU 2497082, IPC G01D 9/00, 10.27.13). A disadvantage of the known system is its applicability only on large aircraft because of the cost, weight and dimensions, which is not acceptable for small aircraft.

Known small-sized system for collecting and recording flight information (ICBM), containing a module for collecting and converting, a control module, a module for processing audio information, a protected drive equipped with a module for the total operating time of a small-sized on-board recorder and engine in various modes, the module for collecting and converting, a control module , the audio information processing module, the protected drive and the total operating time of the ICBM and the engine in various modes are interconnected via an internal bus (RU 2454 713, G06F 17/40, 03/09/11) (prototype).

The disadvantages of the known system are limited functionality:

- lack of reception and processing of video information;

- insufficient bandwidth information on the internal bus.

The objective of the invention is to expand the functionality of the known system (see RU 2454713 G06F 17/40, 09.03.11), as the closest in technical essence and the achieved result, adopted as a prototype, which through the introduction of additional buses and a video processing module expands the functionality registration system, increases the amount of bandwidth of recorded information, which reduces the time of investigation of an incident due to the prompt receipt of registered video information.

The technical result is achieved by the fact that the registrar contains a module for collecting and converting, a module for processing audio information, a protected drive, a module for processing video information, a module for the total operating hours, a control module, and the recorder has information inputs and outputs for connecting to sensors and systems of the controlled object, for operational on-board storage (if available at the facility), to ground-based information processing equipment and on-board information display system (if available at the facility). The registrar is characterized in that it includes an additional video processing module 5 and instead of one internal serial bus, independent serial buses are introduced:

bus 1 - between the control module 7 and the collection and conversion module 2 and the total operating time module 6;

bus 2 - between the control module 7 and the audio information processing module 3;

bus 3 - between the control module 7 and the protected drive 4;

bus 4 - between the control module 7 and the video processing module 5.

The drawing shows a structural diagram of a registrar. Registrar 1 consists of modules: a module for collecting and converting 2, a module for processing audio information 3, a protected drive 4, a module for processing video information 5, a module for total operating time 6, a control module 7, and buses 1-4.

The data logger operates as follows. Information (data) coming from sensors and systems of the monitored object to the information inputs of recorder 1 is converted to digital form in the collection and conversion module 2 and, through the control module 7, is converted to the form required for writing to the protected drive 4.

A program for processing incoming information, a program for connecting sensors and systems, the frequency of their polling, the structure of the information frame recorded in a secure drive, is developed for each specific application of the registration system.

Identification data (board number, date, astronomical time, etc.), which are also converted for recording into information frames, can be entered into the recorder 1 from the control panel or from ground processing equipment. The entire memory area of the protected drive 4 is divided into the information area, where all registered information is stored, and the service area, where special information and programs are stored, which are necessary for linking the registration system to a specific control object.

In the module for processing audio information 3, the incoming audio information at its inputs from an airplane intercom and microphones is converted to digital form, processed using special algorithms to reduce the memory required for its registration (data compression), and transmitted via bus 2 to the control module 7 Through the control module 7, it is recorded on the bus 3 to the protected drive 4, while the information coming from individual sound channels is written to separate zones of the information area of the memory, completely allocated for this.

The video information entering module 5 is compressed by the selected algorithm (for example, MJPEG) and recorded in a specially allocated area in the protected drive 4.

The recording time of parametric, audio and video information is set in the technical requirements for the registrar with the organization of recording of the “ring” type.

In the process of converting into recorded audio and video information, time stamps obtained from parametric information are periodically added, which provides a general time synchronization of all information flows in the system.

The accumulated operating time module 6 is a non-volatile memory in which, upon power-up, the total operating time of the recorder 1 is recorded, the total operating time in flight is determined by the presence of one-time commands to turn on the engine, squeeze the landing gear or other signs of flight mode, the total operating time of the engine and the operating time of the engine in various operating modes It is recorded according to information from the engine speed sensor and the engine temperature sensor. All excesses of the permissible operating modes of the engine are stored in the non-volatile memory of the total operating time module 6, and during ground handling a decision is made on further operation or sending the engine for repair, which affects flight safety.

All the work of the recorder 1 is controlled by the control module 7, made on the basis of a parallel multi-controller system. This multi-controller system provides parallel streaming data processing in real time and includes controllers:

central computing controller;

bus controller 1 (parametric information);

bus controller 2 (audio information);

4 bus controller (video information).

The central computing controller collects parametric, sound and video information, formatting and recording via bus 3 to a secure drive 4. At the same time, the central computing processor controls the bus controllers 1, 2, 4, which provide information compression using built-in algorithms in order to increase channel bandwidth , and analyzes the built-in control of each module with the issuance of an integral signal of serviceability to the operator and communication with the ground processing equipment in deformations of.

The use of parallel streaming data processing on buses 1-4 by parallel computing structures allowed to increase the throughput of information with minimal weight and size characteristics of the registrar.

The exchange of information between the registrar 1, the on-board information display system, ground processing equipment, the control panel is carried out bidirectional communication via a serial code.

Given that modern drives use high-capacity non-volatile memory chips, that is, the ability to record video information of the entire flight. If necessary, the operator can programmatically set any algorithm for recording video information.

Thus, the presence of the video information processing module 5 in the recorder 1 and the registration of video information in the secure drive 4 will allow in the event of an accident to evaluate piloting techniques during take-off and landing and during the flight, analyze the operation of the main systems of the object, the information of which is displayed on multifunction indicators, register images of the cockpit space together with information about the state of equipment, aircraft systems and sound information, which significantly increased to the accuracy of the processing of flight information regarding the fulfillment of the flight mission, as well as to reduce the time of investigation of a flight accident while maintaining optimal weight and size characteristics of the registrar.
