ABSTRACT
GSM (Global System for Mobile communications) is an open, digital cellular technology used for transmitting mobile voices and data services. Here we are using this only for transmitting and receiving the messages. GSM wireless data module is used for remote wireless applications, machine to machine or user to machine and remote data communications in many applications.
The communication used in this project is the mobile communication. GSM (GLOBAL SYSTEM FOR MOBILE COMMUNICATION) modem is connected to the micro controller through a max 232 which is a TTL level converter.
The concept of this project to control the home appliances remotely through GSM. To interface the GSM we use a microcontroller with serial communication using MAX232. Initially we need to interface the home appliances that we need to control remotely to the microcontroller. If we want to control the appliances without we present in the region we need to send a Pre-defined message to the GSM which is included in the program. The message that we sent is collected serially by the microcontroller. When a message is received from the GSM, the microcontroller displays that message on LCD and will do the corresponding operation for that number like switching the devices ON or OFF. The microcontroller sends a reply message to the user number which is also a Pre-defined one stating which appliance got activated and simultaneously displays it on the LCD. We can connect as many appliances as we want and can control those using GSM.
IR and RF communications are limited to a certain area where GSM can be operated from anywhere in the world to control the appliances. So, this GSM communication is better, secure and user friendly. This complete process depends on only one factor i.e. Signal for GSM. If this GSM unit is placed in a place where it gets the maximum signal the process goes on.
GSM Based Ticket Reservation System projects main idea is to develop a application through which users can books bus and train tickets through mobile. GSM technology is used to develop this application.
In existing system most of ticket reservations are done through web portal sites. As mobile technology is increasing and there is scope for developing new applications for mobiles.
Other wireless technologies like IR and RF are limited to certain distance so GSM technology can work from all over the world so by using this technology users can access application from all over the world. Compare to other wireless technologies GSM is secure and consistent. This system entirely depends on the signal strength of the Mobile.
Applications for this are Industries with heavy parameters to handle, complicated areas where we can’t monitor the conditions manually; these are Now-a-days used in all kind of industrial and commercial complexes.
