AUTOMATIC BUS STATION ANNOUNCEMENT SYSTEM
ANTENNA
Message section
3. WORKING EXPLANATION
The above fig shows the complete circuit diagram of automatic bus station announcement system. It consists of a transmitter, receiver (main circuit) and a message section.
Transmitter:
The transmitter circuit transmits the code of each bus from the bus. To generate the code and the address we use an encoder IC HT12E. The encoder has an 8 bit address and 4 bit data lines. Through these bits we can select any code for a bus. The ad ....etc

1. Introduction

Voice morphing means the transition of one speech signal into another. Like image morphing, speech morphing aims to preserve the shared characteristics of the starting and final signals, while generating a smooth transition between them. Speech morphing is analogous to image morphing. In image morphing the in-between images all show one face smoothly changing its shape and texture until it turns into the target face. It is this feature that a speech morph should possess. One speech signal should smoothly change into another, ....etc

in this project need to designe a circuit which contains a micro controller which Sends the serial data through its serial port every time after resetting. Then it sends the data by RF using DTMF tones.
Now after transmitting the data micro controller wait for some time and then again transmit it.

Information transmission by IR:-
These informationâ„¢s are pre feeded into the microconrollers ROM and by using infrared LED in the following way :-
As we know that sensors only detects 38 KHz IR signal so we modulate the 38KHz signal ....etc

Present project is designed using 8051 microcontroller to avoid railway accidents happening at unattended railway gates, if implemented in spirit. This project utilizes two powerful IR transmitters and two receivers; one pair of transmitter and receiver is fixed at up side (from where the train comes) at a level higher than a human being in exact alignment and similarly the other pair is fixed at down side of the train direction. Sensor activation time is so adjusted by calculating the time taken at a certain speed to cross at least one compart ....etc
