INTELLIGENT WIRELESS TALKING BUS STOP

Abstract

This paper is about a bus system that uses Wireless Sensor Networks (WSNs).A ZigBee unit is provided to the blind people in the bus station. This is recognized by the ZigBee in the bus and the presence of blind people in the bus station is indicated in the bus. This will help the bus to stop in that particular station. The bus that has to be  taken by the blind is notified to him with the help of speech recognition system HM2007. The input about the place that has to be reached is given by the blind using microphones and the voice recognition system recognizes it. The microcontroller analyzes the input and the corresponding bus numbers are generated in accordance to the location provided by the blind. A voice synthesizer APR 9600 is used to convert the bus number into audio output. The bus number is sent from the zigbee transceiver in the bus to the transceiver in the blind’s zigbee and it is announced to the blind by means of headphones. This helps blind to take the right bus parked in front of him and a GPS-634R that is connected with the controller and voice synthesizer which produces the audio output announces them when the destination is reached. Zigbee also identifies the blind in bus station and the number of bus parked in the bus station. When both the numbers matches then the buzzer in the bus unit sends the alarm.
