gsm based sms notice board with moving message display

ABSTRACT
In the last few decades, communication technology has developed by leaps and bounds. The employ of “Embedded System in Communication” has given rise to many appealing applications. There are numerous places which need very important notice to be displayed like colleges, hospitals, restaurants, shopping malls, theaters, public transportation, share-market, traffic signs, highways signs etc. Several firms are mechanized audio / video systems like public announcement system, CCTV, programmable sign boards etc. However of these systems are generally hardwired, complicated in nature and not easy to expand. So, by adding wireless communication interface like GSM to those systems, we will overcome their limitations. This work contains a mixture of wireless technology with LED Display Boards formalized by designing and integrating the hardware and software with AT89S51 microcontroller, GSM module, and moving LED display. The message is distributed through a mobile phone which is accepted by the GSM module SIM. Number authentication is finished by AT89S51 microcontroller and the stored numbers in EEPROM is compared with the incoming number. The message will be valid solely when the incoming cell phone number is validated. Authentication result is displayed on LCD whether the number is matched or not matched and the message is finally displayed on moving LED (Light emitting diode) display. Additional a similar SMS is itself sent by GSM module to Multiple LED Display Boards that are connected via completely different GSM modules.Wireless communication has announced its arrival on big stage and the world is going mobile. We want to control everything and without moving an inch. This remote control of appliances is possible through Embedded Systems. The use of “Embedded System in Communication” has given rise to many interesting applications that ensures comfort and safety to human life. The main aim of the project will be to design a SMS driven automatic display toolkit which can replace the currently used programmable electronic display. It is proposed to design receive cum display toolkit which can be programmed from an authorized mobile phone. The message to be displayed is sent through a SMS from an authorized transmitter. The toolkit receives the SMS, validates the sending Mobile Identification Number (MIN) and displays the desired information after necessary code conversion. The system is made efficient by using ‘clone’ SIMs of same MIN in a geographical area so that the same SMS can be received by number of display boards in a locality using techniques of time division multiple access. Started of as an instantaneous News display unit, we have improved upon it and tried to take advantage of the computing capabilities of microcontroller. We envision a toolkit that will not only display message but also can be used to do some mechanical work. Looking into current trend of information transfer in the campus, it is seen that important notice take time to be displayed in the notice boards. This latency is not expected in most of the cases and must be avoided. It is proposed to implement this project at the institute level. It is proposed to place display boards in major access points. The electronics displays which are currently used are programmable displays which need to be reprogrammed each time. This makes it inefficient for immediate information transfer, and thus the display board looses its importance. The GSM based display toolkit can be used as a add-on to these display boards and make it truly wireless. The display board programs itself with the help of the incoming SMS with proper validation. Such a system proves to be helpful for immediate information transfer.The system required for the purpose is nothing but a Microcontroller based SMS box. The main components of the toolkit include microcontroller, GSM modem. These components are integrated with the display board and thus incorporate the wireless features. The GSM modem receives the SMS. The AT commands are serially transferred to the modem through MAX232. In return the modem transmits the stored message through the COM port. The microcontroller validates the SMS and then displays the message in the LCD display board. Various time division multiplexing techniques have been suggested to make the display boards functionally efficient. The microcontroller used in this case is Philips P89C51RD2BN. Matrix Simado GDT11 is used as the GSM modem. In the prototype model, LCD display is used for simulation purpose. While implementation this can be replaced by actually display boards. The results presented in the thesis support the proper functionalities and working of the system. The timing diagram suggests the response of the modem to various AT commands.

OBJECTIVESThe main objective of the study is to gain information and knowledge in developing a real time application. Apart from this, to realize the information of Micro Controller, GSM modem and the way in which these may be accustomed receive messages and show on display board. The working of the modem may be controlled by “AT” commands. Display board is connected to the system simply to indicate that, it is possible to regulate various notice boards using micro controller. The planned system is based on ATMEL 89S51 µcontroller. For this work we tend to use the software like Embedded C for programming the application software system to the microcontroller.

INTRODUCTION
In today’s world of technological advancements communications and management is necessary in any part of the world. The novel idea of this project is to receive message through mobile phones and send it to Display board for display. This project is basically a micro controller- based design used to control remote display board. Now- a -days people from different parts of the globe are ready to communicate with one another among fractions of seconds. GSM (Global system for mobile communication) network is among the foremost wide used wireless communication networks these days for calling or SMS (Short message service). The utilization of “Embedded System in Communication” has given rise to several fascinating applications that ensure a cushy and secure human life. This work aims at developing a system that will show the message received by the GSM module. Microcontroller will then control the system by doing verification and so creating it more secure than other display systems. This system is simple to use in day to day life by any-one and at any place (globally). The large outlets and shopping centers are using the digital moving displays currently. In terminus and bus stands everything that’s price tag information, platform number etc is showing in digital moving display. However in these displays if they need to vary the message or style they need to travel there and connect the display to LAPTOP or PC. Suppose the constant message if the person wish to display in main centers of the cities, means that he has to go there with laptop and alter the message by connecting into laptop. This method is also additionally helpful for police or army .i.e. displays are going to be connected to any or all the main centers in city if they need to display messages regarding something crucial within 5 minute, that they cannot. Thus keeping this in mind a brand new display system which may be accessed remotely, using the GSM technology to create the communication between microcontroller and mobile was designed.

CONCLUSION
By employing the concept of wireless technology within the field of communication we are able to create our communication more economical, and faster, with greater efficiency. We can display the messages and with less errors and maintenance. This model will be used very efficiently in institutions like chain restaurants whereby the order and special discounts will be displayed in the least branches simultaneously, in colleges wherein students and staffs will be informed simultaneously in no time. It will be found out at public transport places like railways, bus station, and airport and also at roadside for traffic control and in emergency situations, it is cost efficient system and extremely, easy to handle. Latency concerned in using of papers in displaying of notices is avoided and the information will be updated by the authorized persons. F
