3. in our day to day life that every one of us uses them no matter if we are aware or not Today 98 of all processors Produced are used in Embedded Systems Because of their power saving features ARM CPUs are dominant in the mobile electronics market where low power consumption is a critical design goal In the existing method if anyone needs information about any transportations information we have to contact that through call for necessary solution And then we need to explain what information we require to the operator Receiving the call by the operator is an optional one so we need wait until they responds to our call for the information we require In the present method we can find the solution to the previous method By using this model there is no need of making calls to get information and no need wait for response from the other side And by this method we can just send message at any time 24X7 It consists of internal data inside the database regarding the general information required for the customer The most interesting point here is no need to keep man power to attend all calls The data services have been gained popularity in cellular networks Short message service SMS is best application in data services SMS is quite simple and the maximum message s length is 160 characters SMS uses only a set of characters as data type In this paper we study the embedded system theory short message service SMS communicat

Mohammad Iliyas Ahmed B Chakradhar International Journal of Engineering Research and Applications IJERA ISSN 2248 9622 www ijera com Vol 3 Issue 1 January February 2013 pp 250 252 Design of Public Transport Service System Based on Short Message Service Mohammad lIliyas Ahmed B Chakradhar PG student Department of Electronics and Communication Engineering CMR College of Engineering and Technology Hyderabad AP India Assistant Professor Department of Electronics and Communication Engineering CMR College of Engineering and Technology Hyderabad AP India Abstract In this paper we proposing the simple public bus transport query system based on short message service SMS Here we analysis embedded system theory and short message service SMS We are combining communication technology and GSM technology Whole traffic routes and timing information is kept in USB per drive and connected to S3C2440A it communicates with GSM and responds to the queries by getting the information from its USB port pen drive GSM will reply to those queries by using AT commands We put forward the system principle block diagram and the hardware circuit of GSM Keywords Advance RISC Machine ARM Global system for Mobile communications GSM pen drive short message service SMS and S3C2440A I INTRODUCTION In modern world embedded systems have become an indispensable part of our life Use of embedded systems has become so common
6. ion technology and GSM technology In this paper we combine GSM technology and computer technology The purpose is to design the public transport system based on SMS As all we know there are so many stops in the big cities which bus will go which stops and Bus numbers and timings will be kept in the database All the bus stops and bus timings will be kept in the data Base We put forward the block diagram and design I METHODOLOGY In our paper we making use of 3 basic things those are ARM9 that is S3C2440A GSM module and to keep all the data we have Pen drive In the basic Block diagram we have ARM9 Microcontroller GSM module and Pen drive We use RS232 to connect the S3C2440A board and GSM module REGULATED POWER SUPPLY S3C2440A GSM MODEM MOBILES Fig 1 250 Page _ 32 bit USB PEN DRIVE Mohammad Iliyas Ahmed B Chakradhar International Journal of Engineering Research and Applications IJERA ISSN 2248 9622 www ijera com Vol 3 Issue 1 January February 2013 pp 250 252 A 3C2440A microcontroller As shown the block diagram in Fig 1 We use the latest SAMSUNG s S3C2440A Its low power simple elegant and fully static design is particularly suitable for cost and power sensitive applications It adopts a new bus architecture known as Advanced Micro controller Bus Architecture AMBA The S3C2440A offers outstanding features with its CPU core a 16 32 bit ARM920T RISC processor designed by Adva
