DETAILS OF BLOCKS

IR Transmitter IR transmitter is an

optical transducer which converts electrical signals into IR rays.

Optical Transducer IR Receiver

IR receiver is an optical transducer which converts IR rays into electrical signals.

Stepper Motor

Stepper Motor Driver Circuit

IRF540 Mosfets are used to drive the stepper motors.

Stepper Motor

Unipolar (Half step sequence) stepper motor are used for rotating antenna .

Slot sensor

It consists of IR light emitting diode(LED1) and phototransistors(Q1). It is used to detect the position of the target.

Firing indicator

A Red LED is used along with a buzzer. Whenever a fire command given, LED

blink once and buzzer beeps.

PC Block The scanning process can be seen in PC RS232 cable is used for the communication

between PC and the Micro Controller.

RS 232 The communication between

microcontroller and personal computer DB 9 female

Micro Controller Unit

A micro controller is used to supervise all these functions.

Battery power supply

A +12v, 7Ah Ni – cad, maintenance free battery is used to power the vehicle.

SOFTWARE

A Micro Controller is used to supervise the above functions according to the program stored in it.

This program is made in assembly language.

At the receiving end, for the computer, the program is written in ‘C’ language to receive the serial data from the Micro Controller and to display the object information on the monitor.

WORKING OF PROJECT if the anti aircraft detects PC will indicate with RED signal. if the our aircraft detects PC will indicate with GREEN

signal.

Conclusion

This project is developed in order to help the Border security system to avoid the human losses by controlling with the wireless communication.

To face new challenges in the present day situation in Military applications unmanned systems are more accurate, flexible and reliable.

Demo purpose, we are using optical sensors instead of microwave in the radar antenna.
