INTRODUCTION:
THIS PROJECT IS
TECHNIQUE WHICH USED FOR FOUND THE FAULT IN COMPLEX NETWORK IT IS CIRCUIT WHICH
OPREATE ON RADIO FREQUENCY (RF) THERE ARE TWO PARTS OF THIS PROJECT, ONE IS
TRANSMITTER AND OTHER IS RECIVER. THE TRANSMITTER CONSIST ON INPUT’S STAGES AND
RECIVER IS CONSIST ON 7 SCETION WHICH IS ( RECIVER MODILE, POWER SUPPLY,
DECODER, MICROCONTROLLER, SERIAL COMMUNICATOR, SERIAL PORT, COMPUTER) THIS TRANSMITTER
AND RECIVER WHICH WE USING IN THIS PROJECT HAS 100ft COVERAGE WITH 10%
TOLERANCE OF THE DISTANCE , IT FREQUENCYRANGE IS 30MHZ TO 300MHZ WHICH IS LIES
IN VHF/UHF SPECTRUM. WE CAN USE THIS PROJECT FOR THOSE THINGS WHICH ARE FAR FROM US, BUT THEIR RESPONSE IS
REQUIRED VERY EARLY. THE RECIVER OF THE PROJECT OPTEATE ON +5V DC SUPPLY AND IN RECIVER 89S51 MICROCONTROLLER ARE USED FOR WRITING
THE THOSE STATEMENTS WHICH WE REQUIRED APPER ON YOUER COMPUER IN CASE FAULT OCCURE . IN THE RECIVER THE MAX 232 IS
USED FOR INTERFACE THE SERILLY DATA TO COMPUTER. AT LAST IN THE WINDOWS WE ARE USING HYPER
TERMINAL WITH TYPICAL SETTING, FOR READ THE REQUIRD STATEMENTS.
WE CAN WRITE REQUIRED INSTRUCTIONS
IN THE MICROCONTROLLER WITH THE HELP OF FOLLOWING LANGUAGES.
1- ASSEMBLLY.
2- C
LANGUAGE.
3- OTHER
LANGUAGES.
PROJECT PURPOSE.
BASICALLY THIS PROJECT IS DESING
FOR SAVE THE GOLDEN TIME OF THE MAN. THE FOLLWING EXAMPLE CAN BE CALLER IT’S
IMPORTANTS .
