Air Traffic Control

At any given moment there are simultaneously several thousands of aircrafts in the skies. It is evident that safe operating of the aircrafts cannot be provided without air traffic control (ATC) services using high-performance equipment. ATC controllers provide organizing traffic flow and direct aircraft in the air and on the ground. Air traffic control radar system forms its integral part. Systems recording the information received from radar equipment and aircraft transponders are widely used for investigation of incidents that may occur in the airport area. In this case the surveillance information from the radar recorders should be timely and accurately represented.

Systems providing air traffic control

Air traffic controllers monitor and direct all aircraft movements. Radar systems both in the airport area and in the Terminal Radar Approach Control (TRACON) facilities permanently detect and monitor all approaching and leaving planes. For each flight listed on an information board in the airport there are two more tracked by the controllers and showed on their screens.  Among other equipment the air traffic controllers use long range radars, terminal area radars and surface radars. The Airfield Surface Detection Equipment (ASDE) system is capable of detecting possible runway conflicts. It ensures detailed coverage of movement on taxiways and runways. Terminal radars provide advisories to the controllers towards improving efficiency in the airspace. Long range radars provide en-route control.

 Radar recording solutions

Radar recording equipment for the most part answers purposes of the traffic radars. Devices available to capture signals from several video sources generally cannot provide VGA signal support and Internet connection (Euresys PCI boards, Skyquest solutions by Curtiss-Wright etc.). This problem can be solved by Epiphan Systems' VGA Grid. The system comprising VGA Grid, VGA Concentrator (also acting as a server) and Ethernet allows for displaying up to 256 VGA signals on one screen.  Any of the signals can be zoomed in and recorded if necessary.  Anyway, when selecting an affordable device for recording information from radars via Ethernet the one should keep in mind the following principal requirements for the solution: ability to support a great number of VGA outputs from air traffic control radars as well as considerably high capture and transmission rates.

How Computer Hardware Works

 

COMPUTER HARDWARE BASICS

 

MICROPROCESSOR:

 

Microprocessor is the brain of any computer. It controls all activities inside the computer. Basically it performs 2 forms of operations - arithmetic & logical operation (internally), learn & write (externally). Learn /write operations are carried out on 2 types of devices - I/O and memory devices. It makes use of the "deal with bus" to select any "location" on these devices, sends a read/write signal over the "management bus" and then the information over the "data bus".

 

MEMORY DEVICES:

 

The CPU shops all data in the pc's memory. There are reminiscence varieties - RAM & ROM

 

RAM (Random Access Memory):

 

This volatile kind is a read & write reminiscence device. This loses its contents when power is shut off.

 

The types of RAM are

 

· DRAM (Dynamic ram) - is similar to a capacitor, as it tends to lose its contents and therefore requires to be refreshed. That is the Computer RAM.

 

· SRAM (Static ram) - Is quicker than Dram and would not require to be refreshed. That is costly and hence only a limited amount is used as CACHE memory within the computer.

 

ROM (Learn only reminiscence):

 

ROM may be programmed utilizing a programmer and then it acts as a "read solely" device. This device is used because the textbook for the CPU within the computer and is named ROM BIOS. It stores all the essential information of programming the units current contained in the system as well as the POST (Power On Self Test) sequence. AMIBIOS and AWARD BIOS are the most typical ROM BIOS.

 

The types of ROM are

 

· PROM (Programmable Learn Only Memory)

 

· EPROM (Erasable & Programmable Learn Solely Memory)

 

· FLASH ROM

 

· EEPROM (Electrically EPROM)

 

· EAPROM (Electrically Alterable ROM)

 

I/O DEVICES:

 

Aside from passive memory units, there are particular controllers within the system, which assist the CPU in performing various operations. These are known as I/O devices. These units embrace Interrupt controller, Timer, Ports, DMA Controller, Floppy Drive Controller, CRT Controller etc.

 

BUSES & EXPANSION SLOTS:

 

These are the means by way of which communication between varied gadgets of the computer takes place and the types are as talked about below.

 

ISA (Industry Customary Structure):

 

ISA bus consists of a 24-bit tackle bus and the sixteen-bit knowledge bus. ISA can support 8MHZ clock speed.

 

MCA BUS (Micro Channel Structure):

 

MCA bus is accessible either in sixteen bit or 32 bit versions. It was developed in a new line of computer systems known as the PS/2 (private system 2). The clock pace is slightly quicker (10MHZ instead of 8MHZ).

 

EISA BUS:

 

EISA has a 32-bit Deal with and Information bus and 10MHZ CLK speed.

 

VL BUS/VESA LOCAL BUS:

 

It's a 32-bit bus which was positioned local to the CPU and therefore its name. Due to this fact it could support excessive bus speeds (that of the CPU).

 

PCI BUS:

 

PCI has many advantages over other bus types. To start with, it helps 64 bit and 32-bit knowledge paths. So it may be used both for 486 and Pentium based mostly systems. PCI can run up to 33MHZ speed and has the advantage of being isolated from the CPU. INTEL developed this bus.

 

PCMCIA: (PC Reminiscence Card Worldwide Affiliation):

 

The PCMCIA was first designed for expanding the memory in small, dealt with computers. PCMICIA'S bus width is simply 16 bits, but a 32-bit model is on its way. There are three varieties of cards specifically

 

· Sort 1 (3.3 m thick)- used for reminiscence card.

 

· Type 2 (5 mm thick)- used for modem and LAN adapter.

 

· Type three (10.5 mm0 thick) - used for commonest applications like PC arduous disk Cards.

 

ADD ON CARDS:

 

These are cards plugged on to the primary board, the mom board (The one that homes the CPU & RAM/ROM Bios). Each performs specific features of interfacing the Motherboard to peripheral device like mouse, Monitor etc. Some Add-ons are discussed below.

 

DISPLAY ADAPTER:

 

These interface the motherboard with the monitor and there are a number of sorts of cards. The variations are in decision, no. Of colors supported and speed.

 

CGA (Shade Graphics Adapter)

 

640 X 200 pixels

 

MDA (Mono Display Adapter):

 

eighty characters extensive 25 lines lengthy

 

EGA (Enhanced Graphics Adapter):

 

640 X 350 mode

 

VGA (Video Graphics Adapter):

 

Advanced variations of SVGA/TVGA which begin from a decision of 640 X 480 pixel

 

AGP (Accelerated Graphics Port):

 

Launched within the celeron/P II based programs, this caters to the demanding multimedia purposes with its excessive performance.

 

IDE I/O CARD:

 

Supports the next functions.

 

SERIAL PORT:

 

Communication exterior to the pc is done serially (bit after bit) by way of this port. It is used to connect communication units like mouse, modem etc.

 

PARALLEL PORT:

 

8 Bit information switch takes place between the computer and an external device. It is usually used to attach a printer.

 

GAME PORT:

IDE (Built-in/Clever Drive Electronics) Interface: This interface is used to communicate with IDE Laborious disks.

 

FLOPPY DISK CONTROLLER:

 

The FDC can assist up to two floppy disk drives. The FDC is related to the system bus and to the DMA controller. It performs information switch in DMA mode.

 

SOUND CARD:

 

This is the cardboard that adds audio results to the computer by providing interface with microphone and speaker. This is used in Multimedia Computers.

 

PERIPHERAL DEVICES:

 

FLOPPY DRIVES:

 

1.forty four MB & 1.2 MB are two forms of well-liked Floppy Drives.

 

HARD DISK DRIVES:

 

ST 506 & ESDI are previous types. IDE arduous disks are common because their value to performance ratio is very good. For very high efficiency, SCSI (Small Computer Systems Interface) is the perfect option, if value will not be a criterion.

 

CDROM DRIVES:

 

CDROM drive is utilized in a multimedia system as it could possibly help all kinds of CD ROMs - be it information CD, Audio CD, Video CD. It has a fantastic advantage of storing about 650 MB of data in a single CD.

 

KEYBOARD:

 

Keyboard interprets the keystrokes into letters or numbers. These letters are interpreted and the computer CPU relying executes instructions on what was sent. Variations by way of XT/AT, no. of keys, kind of keys used could also be observed.

 

MOUSE:

 

To work together with the photographs (ICONS), a particular pointer machine was launched into the pc world. This device is called mouse and is linked to the serial port.

 

The mouse accommodates a round ball that makes contact with rollers-one for X-axis (the horizontal) and one for Y-axis (the vertical). Moving the mouse causes the ball to roll, and the ball, which is in touch with the 2 rollers, causes them to turn. That is used for moving clicking the mouse buttons makes a pointer head on the screen and selection.

 

SCANNERS:

 

Along with keyboards and pointing devices, there may be another quite common method of getting data into the computer. A Scanner is used to scan an image (say from a photo) and editing may be executed using an acceptable software.

 

MONITORS:

 

The monitor receives video alerts from the pc video adapter card and displays the video info as pixels (picture components) on the monitor screen. A variety of screens ranging from CGA mono to SVGA color can be found for customers to choose from (although the previous is completely obsolete).

 

CONFIGURATION SETUP:

 

That is the place we define the system configuration. That is completed only when the system is assembled and configured for the primary time or when it is upgraded. (One could enter the SETUP by pressing "Del" key as the system is powered up). Different BIOS' assist completely different choices but probably the most important ones, which are found on all programs, are listed below.

 

DATE & TIME: It displays the correct Date & Time. It needs to be set when system is first installed.

 

FLOPPY TYPE:

 

To outline the Floppy drives connected (1.2MB or 1.44MB).

 

HARD DISK TYPE: To select the Exhausting disk sort (Major or secondary)

 

DISPLAY TYPE: Its choose the forms of video adapter used for the system monitor.

 

CACHE ENABLE/DISABLE:

 

This class quickens the Reminiscence access. (Default value: Enable) and defines presence or absence of cache memory.

 

QUICK POWER ON SELF TEST: Its hurries up the Power On Self Test after you energy up the computer.

 

PASSWORD SETTING: This lets you set the System password.

 

POWER MANAGEMENT: This category lets you choose the sort (or degree) of energy saving.

 

LOADING DEFAULT VALUES:

 

There are many parameters, which have to be outlined in the CMOS setup, and one might not want to achieve this manually. This selection masses sure default values, saved in the BIOS ROM, which have been defined by the producer for optimum system performance.

 

ENABLE/DISABLE ON BOARD FUNCTIONS:

 

To enable/disable sure onboard capabilities like Floppy Disk Control and so on (This is applicable only to integrated Motherboards the place the ADD ON functions are built-in on the Motherboard itself).

 

PNP FEATURES: This class is used to configure the PCI Bus slots.

 

IDE AUTO DETECTION: This allows you to detect the IDE Hard drives automatically.

 

SAVING & EXITING:

 

This allows you to save the brand new setting value within the CMOS memory and proceed with the booting process.

 

POST (POWER ON SELF TEST):

 

This POST firmware is saved in ROM on the motherboard. This POST is a collection of a easy program to check and catch faults in different parts and circuits. It assessments the microprocessor, interrupt controller, PPI, DMA controller, ROM, RAM, peripheral controllers etc.

 

SYMPTOMS:

 

In case of error detection during POST, indications like error beeps/error messages helps troubleshoot problems.

 

SPEAKER:

 

With the assistance of speaker error beeps, we can troubleshoot faults. Each fault causes the speaker to emit totally different patterns of beeps.

 

DISPLAYED ERROR MESSAGES:

 

When system is powered on, error message will be displayed on the screen (Floppy disk fail), if the Video Adapter is functional.

 

DIAGNOSTIC CARDS:

 

The superior diagnostic add on card captures particulars of POST sequence and shows a hexa code which may be used for in-depth & correct prognosis of a POST problem.

 

CDROM DRIVES:

 

A computer CD-ROM drive uses small, interchangeable, plastic-encased discs from which knowledge is retrieved utilizing a laser beam, very like music compact disc. And like a music CD, a computer CD-ROM shops vast quantities of information. This is achieved by utilizing light to record knowledge in a kind that is extra tightly packed than the relatively clumsy magnetic learn/write heads a standard drive must manage.

 

The drive is managed by a software in your PC that sends directions to controller circuitry that's either part of the computer systems motherboard or on a separate board installed in an expansion slot.

 

How a CD_ROM drive works?

· A motor consistently varies the rate at which CD-ROM disc spins so that regardless of the place a element, referred to as DETECTOR, is located in relation to the radius of the disc, the portion of the disc instantly above the detector is at all times at the similar speed.

 

· The laser tasks a concentrated beam of light that's additional focused by a focusing coil.

 

· The laser beam penetrates a protecting layer of plastic and strikes a reflective layer that appears like aluminum foil on the bottom of disc.

 

· The floor of the reflective layer alternates between lands and pits. Lands are flat floor areas; pits are tiny melancholy within the reflective layer. these surface are file of the 1s and 0s used to retailer data.

 

· Lights that strikes a pit scattered. However gentle that strikes a land is reflected instantly again at the detector, where it passes by way of a prism that deflects laser beam to a LIGHT-SENSING DIODE.

 

· Every pulse of light that strikes the sunshine-sensing diode generates a small electrical voltages. These voltages are matched against a timing circuit to generates a stream of 1s and 0s that can understand.

What kind of slot do I have for a video card? PCI, PCI-E, or VGA?

I would like to get a new video card (my current integrated Intel Pentium one isn't too good for games).

My OS is Windows XP Professional and the computer model is a Dell OptiPlex GX280.

Here are some links to pictures
