Anti-collision Detection System

As it is needed for every vehicle, such a system which detects the obstacle or another moving vehicle and reduces the speed to minimum. If obstacle still comes near to vehicle then it must stop the vehicle automatically. It is possible to construct such system using one IR Transmitter and two IR Receivers with slight less efficiency with one another. The working of system is explained in Brief of Block Diagram & its Description section.

The system’s IR Transmitter and IR Receivers must be fitted in front of vehicle and system must be supplied with power only when vehicle starts moving. That means power supply line of the system must be in series with ignition key of vehicle, and when rider switches ON the ignition key vehicle starts and system comes into action.

MAIN FEATURES OF THE SYSTEM

1. Effective in implementation.

2. Low power consumption, and compact size,

3. High reliability, due to the usage of power semiconductor devices.

BLOCK DIAGRAM & ITS DESCRIPTION

The Obstacle Detection System FIG,3 is explained in Brief as follows:

There are two IR Receivers fitted both sides of single IR Transmitter. The IR Receiver #1 is normal receiver where as IR Receiver #2 is slightly less efficiency receiver. So when IR rays transmitted by IR Transmitter hits to any long distance obstacle and comes back, they are received only by IR Receiver #1. Its output goes HIGH and which in turn energizes switching stage relay. The relay’s N/C [Normally Connected] pin supplies normal voltage to motor from Variable Power Supply to move vehicle in normal speed. When relay gets energizes then N/O {Normally Open] pins comes into action and supplies Low voltage from Variable Power Supply to run motor in low speed. Thus vehicle reduces its speed when any obstacle is observed in front of vehicle in a safe distance.
