The Multi-function Automatic Broad-casting System For Bus Based On RFID

In the process of informationization in China, a city's public transportation industry becomes the measuring level and a reference point of urban civilization for informationization as an important window. The developing level of public transportation not only represents the image of a city,but also relates with everyone in the city. The Broadcasting System for Bus well embodies services and careness for passengers.At present, the Broadcasting System installed on the bus is still operated manually with push-button, which may have potential safety hazard. In order to control the speed of each bus, Public Transport Company has to send a worker to record the time when the buses in the same line arrive at the station. The television installed on each bus transmits the same programme all day, which hardly satisfies every passenger. So the cost of advertisements broadcasted on the TV can' t drop. Based on the studies on present public transportation system, the dissertation aims to design the multi-function automatic broadcasting system for bus, which technologically combines ARM with RFID. RFID is a kind of non-contact automatic identification technology; it identifies and obtains the corresponding data automatically through the RF signal. This system can not only realize the basic function of automatic broadcasting but also do attendance checking for buses' arrival time as well. At the same time, it has realized Play AD at Real-Space-a new kind of advertising on the bus, thus enhencing the informationization level of public transpotation industry , reducing management costs, satisfing most passangers favors, improving the serving and operating level of automatic broadcasting and then makes the city more beautiful.
