AUTOMATIC VEHICLE ACCIDENT INFORMATION SYSTEM-TWO WHEELER.doc (Size: 78 KB / Downloads: 142) AUTOMATIC VEHICLE ACCIDENT INFORMATION SYSTEM SYNOPSIS In the fast moving world, no body is ready to look what’s happening around them. Even an accident occurs, nobody cares. So we found out a solution for this problem and we develop a project called “automatic Accident Information system” system. We have got the sensor called Accident sensor which is nothing but a force sensor. This Force sensor senses the vibration that occurs during the accident and the output is given to FM transmitter unit. The modulated signal is then given to a FM modulator. At the Receiver side the modulated signal gets demodulated by using FM demodulator. The demodulated signal is then given to FSK demodulator. The final output signal is then given to a relay and alarm circuits. INTRODUCTION Nowadays Automation occupies various electronic sections by its comfortable nature. This is an era of automation where it is broadly defined as replacement of manual effort by electronic power in all degrees of automation. The operation remains an essential part of the system although with changing demands on physical input as the degree of mechanization is increased. Degrees of automation are of two types, viz. Full automation. Semi automation. In semi automation a combination of manual effort and electronic power is required whereas in full automation human participation is very negligible. BLOCK DIAGRAM 1. TRANSMITTER:- 2. RECEIVER:- APLLICATIONS AND ADVANTAGES 1. Transmitter and receiver is compact in size 2. It is very economical. 3. As we said earlier it is easy to giving information even when we are hidden from the devices through a closed room or concrete wall. 4. Receiving problem is restricted. 5. This project provides another facility to control the speed of the fan by gradual regulation. LIMITATIONS 1. A wide range of frequencies cannot be tuned with the help of this remote control. 2. There is a possibility of heavy line fluctuations and disturbances to occur. In case of TV or Radio, at certain times, the receiver will be liable to pick up the disturbances such as sound of vehicles and other things. 3. It will not be possible to increase the range of channels. 4. Interruption in the frequency range is possible. The above statement states that, if we have a frequency range say 10 MHz, 12MHz and so on, then there will be an interruption in the middle frequencies like 11 MHz, 9 MHz etc. |
