Introduction to DATA ACQUISITION. Working Background Advantages Real life applications Future prospects Conclusion

Introduction(what is it???) The process of gathering real-world data

to validate models and simulations.

In its broadest sense , data acquisition is the process of gathering information in an automated fashion from analog and digital measurement sources and presenting that information in meaningful way.

Working Background

Signal Conditioning

Amplification

Isolation

Filtering

Linearization

Analog to digital convertor

Step size=1/2^n * vref , where n is no of bits used

n-bit ADC Digital outputAnalog input

Advantages

Does not require programming. Enables developers to design the custom

instrument best suited to their application. Examples- TestPoint , LabViEW ,

SnapMaster. Involve the use of programming language

like c++ , BASIC, development tools

Real life application

Refrigerator Water control system Water boiler Electric arc furnace Life support system Blood pressure monitoring Heart beat monitoring Oxygen monitoirng

Electric arc furnace Industrial arc furnace temperatures can

be up to 1800 *c, while laboratory units can exceed 3000*c

The electrodes are automatically raised and lowered by a positioning system which may use hydraulic cylinders

By using of electronic device it sends a data to the furnace so that it automatically stop working

Life Support System

Providing breathable oxygen Removing carbon dioxide humidity Portable life support system contained a

radio transceiver and antenna for communication

Plss controls were provided the remote control unit(RCU) mounted on the astronaut’s chest

HEART BEAT MONITOR

Sensor fusion algorithm allow these monitors to detect core temperature and dehydration

When a heart beat is detected a radio signal is transmitted,which the receiver uses to determine the current heart rate

This signal can be simple radio pulse or a unique coded signal from the chest.

Future prospects

Have found applications. incredibly broad usage in areas as diverse as monitoring agricultural

To testing the next generation NASA space telescope.

Expect to see continued growth and adoption of USB and added flexibility with onboard FPGA.

CONCLUSION

Thus , finally we conclude that data acquisition is the need of time which is required in varieties of field from life saving process to industrial and product manufacturing process .
