The Automatics Recognition and Broadcasting System in Bus Station Based on RFID

Many buses are installed automatic bus-stop broadcasting systems.But in fact,the recognition of bus stops and voice broadcasting are operated manually by the bus driver.This not only adds the driver′s operations,but also may cause dangers to the bus.This article introduces a new method based on RFID techniques,to realize real automatic bus-stop recognition and broadcasting.By this new method,the identification of bus stops and voice broadcasting can be performed without the involving of the driver.The receiver which is installed on a bus receives and decodes the RFID signals which are generated by the transmitter installed on a bus stop,and controls the broadcasting system to perform voice broadcasting.Thus,a real automatic broadcasting system is achieved.Because both the identification of bus stop and the broadcasting are not done manually,the driver′s operations are lessened.Therefore the security of a bus is more guaranteed.
