Abstract

An on-board audio and video player containing a removable information device, characterized in that it contains the main unit of the player and its control panel, while the main unit includes a processor module, a built-in power supply, an interface module with the control panel, sound and video cards, equipped with an input from on-board notification equipment, and the information device is made in the form of a removable hard disk, while the processor module is single-board and installed on the backplane, on which are installed ukovye and graphics cards, which are recorded on a hard disk digital information is converted to analog stereo information, for example, up to ten stereo.

Description

On-board audio video player.

The proposed utility model relates to the field of avionics and can be used, for example, for translating various audio-video programs on board an aircraft and for working together with entertainment systems for civilian aircraft passengers.

Known equipment for reproducing musical programs - the product “Arfa-MB, designed to play on board passenger aircraft music programs previously recorded in the studio using the product“ Arfa-MB on a removable cassette (see technical specifications ЛШЗ.832.029).

The main unit of the Arfa-MB product is an on-board tape recorder. Management, control and indication of the operating modes of the on-board tape recorder are carried out using the controls and alarms that are installed on the tape recorder, as well as through remote control circuits.

As a carrier, a magnetic tape of 6.25 mm type RE, DR or magnetic tape of domestic production type I-4404-6 GOST 22507-77 TU 6-17-98684 is used.

The on-board audio player is a multi-channel device and is designed as a structurally complete unit. The block case has a modular collapsible design.

The stereo signals from the audio video player enter the passenger entertainment audio system, such as the passenger audio service system (CAO). Through an easily removable rear panel, the audio player has access to the user port, as well as to the port for connecting a monitor and keyboard.

- module for interfacing with the control panel (5);

keyboard controller (6);

sound cards (7, 8.9);

a device for storing information in the form of a hard disk (10);

video card (I).

The processor module (3) is designed as a single-board design and is based on a Pentimn III processor with a clock frequency of 450 Hz, 115 V. The module performs various functions in the control and communication system, including compatibility with the WINDOW operating system (“window”) .

On the processor module, expansion slots (slots) are made, in which various boards are located - a video card (11), sound cards (7, 8, 9) and more.

Sound cards provide the translation of digital audio recording signals into analog recording signals (for example, up to 10 stereo channels) recorded on the player’s hard disk.

The information storage device (10) is made in the form of a hard disk, which is the main memory device. On it is a work program and phonograms. Recording (dubbing) of phonograms on a hard disk is carried out in laboratory conditions, having previously removed it from the audio video player. The disk is connected to a computer, from which phonograms are recorded. The built-in power supply module (4) has stabilized output voltages, for example, +5 V, 10 A; -5 V, 05A; + 12 V, FOR; -12 V, 06A, etc. The power supply is threaded from the mains from a continuous current network of 115 V, 400 Hz.

Its power is not more than 100 W, it generates a signal “threading is normal for the non-bass operation of the processor module.

The interaction of all modules of the on-board audio video player is as follows: The processor module controls the operation of all other modules of the player, and also processes the signals received from these modules.

The interface module (5) switches all the player modules with the contacts of the output connector, through which communication with other passenger service and entertainment systems is carried out.

The equipment is controlled from the control and display panel (1) from the “Start / Stop video and“ Start / Stop audio.

After power is supplied, the AP-B automatically enters the built-in control mode, after which the AP-B enters standby mode. As soon as the logical signal “Start-up - audio player (AP-B) will automatically enter the main mode - playback and transmission of audio programs to the input of the SAOP-B system.

Disabling and stopping the transfer of audio programs is carried out by pressing the "Reset.,

When a control logic signal is received from the ABQIy system, the audio player goes into pause mode. In this case, the phonogram playback stops and the “Pause. When the control signal from the intercom system ceases, the audio player will continue playing the phonograms. /.

3 self tests - POST stored in BIOS chip. POST does

testing the processor, memory and system I / O, as well as configuring all software-controlled hardware on the motherboard. After testing and configuration, POST initializes the loading of the operating system. When passing through each section, the POST writes its code (number) to the diagnostic register. This register is physically located on a special diagnostic board installed in the system bus slot. During testing, POST can display diagnostic messages in the form of a sequence of short and long beeps (when installing the built-in dynamic head), and then successfully initialize the graphics adapter, short text messages are displayed on the monitor screen when it is connected to an audio player.

Currently, design documentation has been developed and an industrial design has been created for certification testing of equipment with its subsequent installation on an aircraft, for example, Tu-324, Tu-204,214; IL-9B-300.
