ABSTRACT
Our project is vehicle theft identification done by thee Radio frequency identification. The preface is the Identification of the vehicle is theft (or) not. In the block consists of
1) Transmitter module
2) Code generator.
3) Receiver module
4) Decoder unit
5) Micro controller unit
6) Relay unit.
Here we are using a transmitter section which will be kept by the vehicle unit and the receiver sections placed at different locations by the police department. The code generator will produce a particular tone frequency for each transmitter. The code is used to distinguish between different transmitters. Using the demodulated signal at the receiver section, the IC HT12 E will produce a four bit output equivalent to the received code signal. The output from the receiver units at different locations are given to a CMOS switch via buffer nearer to the Micro controller unit, connected through wire. The output from the decoder section is fed to the MC via buffer unit and, it is process and verify by using PIC asm program.
