pdf innovative college bus information system to students using gsm

ABSTRACT:

Now a days, Everybody is having and using mobiles. Somebody is having the interest to know college bus information in their respective areas. Our project is designed to send an SMS as text with bus information. Here in this project code is implemented in RIDE software. The whole system is placed in a bus and can be controlled by the conductor or driver. There are some switches which can be used select the stage. Whenever bus is nearer to the stage corresponding stage switch can be pressed by the driver. Then automatically information regarding the bus can be send to the students which are already
registered in that bus stop. GSM module is used to transmit the data to the students. GSM module communicates with microcontroller via MAX232. Thus LCD unit in the system will display the information to commuters in the bus stops. This system is very much cheap, easily implementable on large scale and very much suitable for countries like India. This system consists of data transfer involves transmitting the data from the bus to the students using the GSM controlled by the bus conductor or driver. This project uses regulated 5v, 750ma power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/18v step down transformer
