Dynamic Display System For Bus Stop Board Based On Embedded System

At present,the travel tool is mainly the public traffic vehicles for most chinese citizens, traffic system is rapidly growing,but the intelligent transportation system has not yet applied in mass transit vehicles.According to the domestic and international the intelligent transportation system profiles,and at present in China intelligent public transport system based on GPS technology is imperfect,combined with related research work about the Granary Temperature Measure System, this paper presents a bus stop board dynamic display system based on embedded system.A bus stop board dynamic display system based on embedded system is mainly composed of two parts: the car system and electronic bus stop board system. Car system mainly transmits sign information to the electronic bus stop, and auto-stop for the passengers on board. Electronic bus stop board system displays information arriving from the vehicle for the waiting passengers,and transmits sign information to the next electronic bus stop.Vehicle system sents information through infrared carrier modulation,after the infrared receiver of a bus stop board system demodulates,ARM microprocessor deals with the relevant information,displaying relevant information in the LCD large screen,at the same time,it constitutes a new sending data packets,transmits to the next electronic bus stop with the wireless transceiver module SRWF-508,a different vehicle route information dynamically display through the relay,complete real-time transmission and displaying of the entire route information. At the same time each terminal will transmit the vehicle dynamic information in real time transimtted to the bus control center for central control through wirless Internet.
