REMOTE NOTICE BOARD IMPLEMENTATION USING GSM COMMUNICATIONABSTRACT

AIM:

THE MAIN OBJECTIVE OF THIS PROJECT IS TO DEVELOP AN EMBEDDED

SYSTEM, WHICH IS USED FOR SPONTANEOUS ADVERTISEMENT USING GSM

TECHNOLOGY.

IMPLEMENTATION:

THIS PROJECT IS IMPLEMENTED 8051 BASED AT89S52 DEVELOPED BOARD

INTERFACED WITH GSM MODEM AND LCD FOR DISPLAYING THE DATA.

DESCRIPTION:

NOW A DAYS EVERY ADVERTISEMENT IS GOING TO BE DIGITAL. THE BIG

SHOPS AND SHOPPING CENTERS ARE USING THE DIGITAL MOVING DISPLAYS

NOW. IN RAILWAY STATION AND BUS STANDS EVERYTHING THAT IS TICKET

INFORMATION, PLATFORM NUMBER ETC IS DISPLAYING IN DIGITAL MOVING

DISPLAY. BUT IN THESE DISPLAYS IF THEY WANTS TO CHANGE THE MESSAGE

OR STYLE THEY HAVE TO GO THERE AND CONNECT THE DISPLAY TO PC OR


STEP DOWN

BRIDGE

RECTIFIER

FILTER

CIRCUIT

REGULATOR

LAPTOP. IF THEY WANT TO DISPLAY MESSAGES ABOUT SOMETHING CRUCIAL

WITHIN 5 MINUTE, THEY CAN’T

HERE WE ARE DESIGNING A NEW DISPLAY SYSTEM WHICH CAN ACCESS

REMOTELY, WE ARE USING THE GSM TECHNOLOGY TO ACCESS THE DISPLAY’S

IS ONE OF THE NEW TECHNOLOGY IN THE EMBEDDED FIELD TO MAKE THE

COMMUNICATION BETWEEN MICROCONTROLLER AND MOBILE.

THIS PROJECT IS A REMOTE DEVICE WITH GSM MODEM CONNECTED TO IT,

SO IF THE USER WANTS TO DISPLAY SOME MESSAGES, HE WILL SEND THE

MESSAGES IN SMS FORMAT. THE GSM MODEM WILL RECEIVE THE MESSAGE AND

THE MICROCONTROLLER WILL UPDATE THE DISPLAY ON THE LCD ACCORDING

TO THE MESSAGE.

THE SYSTEM USES A COMPACT CIRCUITRY BUILD AROUND FLASH

VERSION OF AT89S52 MICROCONTROLLER WITH A NON VOLATILE MEMORY

PROGRAMS ARE DEVELOPED USING EMBEDDED C, COMPILED USING RIDE

TOOL. ISP IS USED TO DUMP THE CODE INTO MICROCONTROLLER.

SOFTWARE:

EMBEDDED ‘C’

RIDE TO WRITE CODE

ISP TO BURN THE CHIP




HARDWARE:

AT89S52 BASED OUR OWN DEVELOPED BOARD

POWER SUPPLY

GSM MODEM

LCD

ADVANTAGES: LOW COST, AUTOMATED OPERATION, LOW POWER

CONSUMPTION.
