Abstract
The main aim of this project is to provide security to the two wheelers. The system automatically locks the vehicle as soon as it receives a predefined message from the user.
This project uses the wireless communication, GSM. To receive the messages from the user mobile, we need a GSM modem. This modem will be interfaced to the microcontroller through serial interface. The modem provides the communication interface.
It transports device protocols transparently over the network through a serial interface. The GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.
If the user is somewhere far from the vehicle and he wants to lock the vehicle right from the place he is standing, he has to send a predefined message to the modem. The controlling unit will be fixed to the vehicle. The controlling unit contains the microcontroller and the GSM modem interfaced to it. The microcontroller continuously checks whether it has received any message from the modem.
When the user sends the predefined message to the modem, the modem receives the message and intimates the same to the microcontroller. The microcontroller retrieves this message from the modem by issuing certain AT and T commands to the modem. Thus, after receiving the message from the modem, the microcontroller automatically locks the vehicle. This will be done perfectly without the involvement of any human. The locking of the vehicle is shown by the relay in this project.
Whenever anyone tries to unlock or take away the vehicle, immediately a message will be sent to the user mobile. The user, after checking the message, can respond immediately to save his vehicle. Even when the user tries to unlock or lock the vehicle, a message will be sent to his mobile. Thus, he may ignore the message in this case.
