THE DESIGN AND IMPLEMENTATION OF A CAR LOCK WITH 5-MINUTES IGNITION DEACTIVATION FACILITY
ABSTRACT
This project deals with the design and implementation of a radio controlled car lock with 5-minutes ignition deactivation facility capable of locking a vehicle using a remote control from a distance. The system is designed in two functional units; the transmitter which is an RF handheld remote control, and the receiver units. The receiver unit is realized in several modules. A tuned radio frequency receiver (TRF) output is used to trigger a bi-stable multi-vibrator configured using CD 4013 whose output is used to trigger the car lock switch. The four doors of a conventional car are represented using four push and hold switches wired to trigger a 5-min delay circuit realized with Ne555 timer in mono-stable mode. The system works in such a way that if your car is snatched at gunpoint, you simply press the remote and the car locks by switching off a green LED before the armed robber zoom off. And once any of the doors is opened and closed, the vehicle automatically comes to a stop after five minutes. And the ignition lamp goes off too. The system also contains a reset switch installed at a recessed location in the car for resetting the locking system when the car is found. Due mainly because of the area of application, the system is chordless.
