1. INTRODUCTION

The Data Recording and Playback Position (DRF) is one of the elements of the Tower and Approach

Integrated Control System.

The main duties of this position are the recording of all relevant data in a convenient order and their

subsequent recognition and playback.

The DRFs is a utility for recording and playbacking. The information of SDDs is saved on tapes.

The process is:

1. SDDs record all data in local files. The data are: Events, monitoring, etc. This data files are sent to the DRFs each hour automatically.

2. When the DRFs receive the files from the SDDs, these ones are recorded on tapes.

3. The DRFs displays to technical staff all files received from the SDDs on a screen as well all files save on tapes.

Also, the DRFs allow monitoring the tapes states, the recorder files, used capacity tapes.

To reproduce information stored in tape it would be enough with:

1st: To gather the necessary files stored in tape. This operation is carried out by means of an intuitive graphic interface.

2nd: The DRF will take charge loading the above mentioned information in the SDD specified by the technician for his later reproduction.

3. PLAYBACK

In the AIRCON 2100 System exist two clear ways to playback one SDD:

1st: PLAYBACK 24h:

This one play all data stored in one SDD.

This data stored is, only, the last 24 hours.

Allow playback more quickly because the recorded data are stored in the same SDD.

Only is possible playback in the same SDD that success occurs because the data are stored in the same SDD.

2nd: PLAYBACK:

Allow this playback it is possible play all success or event stored in tape.

It is possible to specify a SDD to reproduce the events.

It is possible to reproduce the events stored of a SDD in another different SDD.

To reproduce in this mode is necessary load data from a tape. Obviously, this load process isn‟t a real time process. It is necessary to wait the all requested data loading.

3.1 STORAGE

In accordance with the playback modes, the system offers two storage modes:

● A Local storage performed in each disc on the SDD position.

● A Central storage on the DRF position.

3.1.1 Local Storage

Each control position carries out its recording using its own local disc. These recordings concern received

data, local configurations (maps, etc.) and the most relevant actions achieved by the controller (for

example: Hand-over actions).

General system information: Messages received at control positions (radar targets, radar/ADS tracks sent

by the SDP, flight sent by the FDP, etc.). This information is recorded making use of compressed files

with one hour capacity.

Each SDD records during a maximum of 24 hours and when one hour file is complete, the system copy

this file in the DRFs and the oldest file is removed immediately.

All SDDs send every hour automatically the last generated files to the DRFs.

When the xx % (defined in a configurable file) capacity of local hard disk is exceeded, the supervisor

position is warned about it.

(DRF-UM)





Date: 09/07/2012

3.1.2 Central Storage

Central storage is performed on the DRFs position:

● Recording files on disc. The information kept in these files is local information concerning every single control position. This files are stored in “local/<proj>/sdd/exec/grabacion/pregrabados” folder waiting to transfer at tapes by

the DRFs.

The list of files pending to transfer to the tapes are stored in ASCII file named "pendientes"

existing in “local/<proj>/sdd/exec/grabacion/pregrabados”

● Data transfer from disc to tape. The information received from SDDs will be saved on tapes by DRFs. The DRFs between 5 and 10 minutes test if they are files on a “local/<proj>/sdd/exec/grabacion/pregrabados” folder to transfer at tapes.

This Recording function is able to keep 9000 files capacity tapes (approximately depending on the SDDs

activities). This offers a convenient interval of time in case of tape unavailability.

(DRF-UM)





4. DRF WINDOWS DESCRIPTION

The main screen is divided in four main areas:

● Position Name. Date and Current Time.

● Commands Area.

It is located at the top of the main screen and allows the display of the tape recording/playback windows.

The colour of the icon informs about the tape use:

■ Yellow colour means that the tape is ready for recording

■ White colour means that the tape is ready for playback

■ Clear grey colour means that the tape is not operative.

● System Warning Messages Area.

● Information Area.

It offers information about recording/playback on every tape.

5. SDD DESCRIPTION (PLAYBACK MODE)

This section describes the playback process on the SDD position.

The information can be recovered from the disc at the SDD position or from the DRF position itself. From

the playback operative point of view, there is no difference between both playback options (24 hours and

historic); the only difference is the way of planning. The 24 hours playback is activated from the SDD

position that is going to be replicated, however, the historic playback demands the previous selection of

the information that is going to be playbacked from the DRF (as described in section 4.).

When the synchronized reproduction between SDD recording and Voice recording is desired, the SDD

rewind forward until the voice recording beginning point, and then the synchronized playback begins from

this point in normal play mode.

5.1 STARTING UP THE PLAYBACK POSITION

Before starting the playback process, the corresponding SDD must be halted from the Supervision

Position (CMD). Once it is not available (OFF in system mode), the controller starts up the playback

function by introducing the Username and Password. The Username for the 24 hours playback is saved

in DBM application.

5.2 WINDOWS DESCRIPTION

A SDD working in playback mode looks very similar to another SDD working in operative mode.

The main difference is the existence of two new windows with their corresponding bi-state icons located

on the Main Menu Window: [PLAYB CTR] y [PLAYB DAT].

Two new windows are displayed when pressing on these new bi-state icons:

● SDD Playback Control Window [PLAYB CTR]

● Playback Status Window [PLAYB DAT]

5.3 SDD PLAYBACK CONTROL WINDOW

This window allows the control of the playback function and appears and disappears by pressing on the

[PLAYB CTR] bi-state icon on the Main Menu Window.

When the colour of the tape is WHITE: the tape is in playback mode.

When the colour is YELLOW: the tape is in recording mode.

6.2 BACKUP FILES NOT COPIED AT DRFS

When the SDD send one file at DRFs, the SDD take two ways, LAN1 or LAN2. If the SDD cannot copy

this backup files, the system need that the technical execute the next actions.

Remark: This procedure is for different cases:

● LAN 1 and 2 broken

● DRF1 and DRF2 disconnected of the LAN

● DRF1 and DRF2 are shutdown when the files are transferred by the SDDs.

6.2.1 The DRF Diagnoses Tape Not Working:

It is necessary to use cleaning tapes for each Unit Tape following a periodic procedure. In other case, the

tapes can corrupt stored data.

In the case when the message "TAPE NOT WORKING" appears in DRF and CMD, after each writting

attempt, it is recommended to do the following steps:

1. Shutdown DRF application which is involved in diagnose

2. Execute the following commands in the corresponding machine:

#rm -r /local/<proj>/sdd/exec/tar1.tmp

#rm -r /local/<proj>/sdd/exec/tar2.tmp

#rm -r /local/<proj>/sdd/exec/grabacion/de_cinta

#rm -r /local/<proj>/sdd/exec/grabacion/directorios1

#rm -r /local/<proj>/sdd/exec/grabacion/directorios2

#rm -r /local/<proj>/sdd/exec/grabacion/pregrabados/*

3. Clean Unit tape and format the tape,

4. Both tapes will appear in REPRODUCTION status. Change the operative status of one of them

5. if it does not fix the problem, then replace the tape.

It is strongly recommended to change tapes periodically (1 month aprox.)

6.2.2 The DRFs Software is Shutdown, Inoperative or LAN Disconnected:

For each SDD is necessary to do the next steps:

1st: The SDD software operative

2nd

: The DRFs software down (software off)

3rd

: In remote mode, and for all SDDs, the technical operator need execute the next command:

Go to DIRECTORY for each SDD: /local/<proj>/sdd/exec/grabacion

Need EXECUTE this command: gunzip *.Z. (Only in the files that not copied at DRF)

(DRF-UM)





4th: Start-up DRFs. In this moment, automatically, the DRFs verify all SDD to copy all files at the

“pendientes” directory of the DRFs.

5th: Is recommended that verify all copied files correctly on tapes.

WARNINGS:

It is very important that the technician see the free space in tapes to recovery data.

Of course, this procedure assures tape data continuity while DRFs is start-up in 24 hours duration.

It is necessary that they don‟t change the tapes or load empty tapes for assure continuity and saved

data‟s.

This process is very slow and need that the DRFs take a several minutes to verify all files and SDD

positions. Is very recommended that don‟t operate with the DRFs until the process are finished.

The DRFs, when start-up, automatically restore all files pending of the SDDs

6.3 DIFFERENT START-UPS OF DRFS

This part explains different states when DRF is restarted.

REMARK:

If one tape is formatted all functions of DRF are disabled. It exists two ways to format tape:

● Format function in DRFs

● Manual format:

○ /local/<proj>/sdd/exec/bin/mtx –f /dev/rmt/0 erase

○ or /local/<proj>/sdd/exec/bin/mtx –f /dev/rmt/1 erase
