1. AUTOMATIC PNEUMATIC BUMPER AND BREAK ACTUATION BEFORE COLLISION
ABSTRACT:
 The technology of pneumatics has gained tremendous importance in the field of workplace
rationalization and automation from old-fashioned timber works and coal mines to modern
machine shops and space robots. It is therefore important that technicians and engineers should
have a good knowledge of pneumatic system, air operated valves and accessories.

“ AUTOMATIC PNEUMATIC BUMPER AND BREAK ACTUATION BEFORE
COLLISION” . This system is consists of IR transmitter and Receiver circuit, Control
Unit, Pneumatic bumper system and pneumatic braking system. The IR sensor is used to detect
the obstacle. There is any obstacle closer to the vehicle (with in 3-4 feet), the control signal is
given to the bumper activation system and also pneumatic braking system simultaneously. The
pneumatic bumper and braking system is used to product the man and vehicle. This bumper
and braking activation system is only activated the vehicle speed above 30-40 km per hour.
This vehicle speed is sensed by the proximity sensor and this signal is given to the control unit
and pneumatic bumper and braking activation system.

2. SCOPE OF THE PROJECT:
We have pleasure in introducing our new project “AUTOMATIC PNEUMATIC BUMPER
AND BREAK ACTUATION BEFORE COLLISION”, which is fully equipped by IR sensors circuit and
Pneumatic bumper and braking activation circuit.
It is a genuine project which is fully equipped and designed for Automobile vehicles. This forms an
integral part of best quality. This product underwent strenuous test in our Automobile vehicles and it is
good.
WORKING OPERATION:
The vehicle speed is sensed by the proximity sensor. The vehicle speed is above the 30-40 Km per
hour, the control unit will activate the IR sensor Unit. The IR TRANSMITTER circuit is to transmite the
Infra-Red rays. If any obstacle is there in a path, the Infra-Red rays reflected. This reflected Infra-Red rays
are received by the receiver circuit is called “IR RECEIVER”. The IR receiver circuir receives the reflected
IR rays and giving the control signal to the control circuit. The control circuit is used to activate the solenoid
valve. If the solenoid valve is activated, the compressed air passes to the Pneumatic Cylinder. The
compressed air activates the pneumatic cylinder and moves the piston rod.
If the piston moves forward, then the bumper arrangement and braking arrangements are activated.
The piston speed is varied by adjesting the valve is called “FLOW CONTROL VALVE”. In our project,
we have to apply this arrangement in one wheel as a model. The compressed air is drawn from the
compressor in our project. The compressed air is flow through the Polyurethene tube to the flow control
valve. The flow control valve is connected to the solenoid valve as mentioned in the diagram.
ADVANTAGES
 . Free from wear adjustment.
 Less power consumption
 It gives simplified very operation.
 Installation is simplified very much.
 To minimize the accident

3.  Safe the vehicle and human being

DISADVANTAGES
 Additional cost is required to install this arrangement in the vehicle.
