The application of IR and PIC microcontroller inexpress bus arrival and identity notification system

Express Bus Arrival and Identity Notification System (EBAINS) is designed to create the convenience for the awaiting passenger in any express bus terminal. This system can provide hassle-free from going to the platform or counter to check the arrival of any particular bus. With this system, each bus has its own arrival indicator at the waiting lobby to indicate its arrival. Transmitters and receivers are installed at buses and platforms to facilitate the detection of bus arrivals. LCD that displays the number of the respective bus is utilized as the arrival indicator. Technically, infrared transceiver was used as transceiver in which the IR transmitter is installed on the bus whereas the IR receiver is installed at the platform. Signal will be encoded before being transmitted. With encoding, the bus is virtually given an identity as each bus is assigned a unique digital code. Besides, IR receiver at the platforms is common to every transmitter on the buses which implies that no matter which platform a bus stops, it can be detected. At the receiver, the received infrared signal is decoded. Decoded signal is then passed to PIC microcontroller chip which determines the number to be displayed accordingly. Basically, the display system for flight departure and arrival information of flight information display system (FIDS) is adapted in this project. Although the function of this system is not as complete as FIDS, it is cheaper and sufficient to solve this problem and satisfy the needs of a bus terminal. The implementation of EBAINS (Express Bus Arrival and Identity Notification System) will surely create a more comfortable express-bus-waiting experience.
