This document describes an automatic pneumatic bumper adjusting system that uses infrared sensors and pneumatic components. The system detects obstacles using an IR transmitter and receiver, then activates solenoid valves and pneumatic cylinders to adjust the position of the bumper. It can stop an oncoming vehicle and requires less human involvement than manual systems. The system has applications for automobiles and industries, providing advantages like lower cost, easier operation and installation, and avoiding wear issues compared to other designs. However, it does require additional upfront costs to implement the automation.

AUTOMATIC PNEUMATIC BUMPER ADJUST
MECHANISM
SYNOPSIS
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. The air is compressed in an
air compressor and from the compressor plant the flow medium is transmitted to
the pneumatic cylinder through a well laid pipe line system. To maintain optimum
efficiency of pneumatic system, it is of vital importance that pressure drop
between generation and consumption of compressed air is kept very low.
The aim is to design and develop a control system based an intelligent
electronically
controlled
“INTELLIGENT
automotive
BUMPER
Bumper
ADJUSTING
system
is
called
SYSTEM”.
Sensor
Operated Bumper Mechanism is consists of IR transmitter and Receiver circuit,
Control Unit, Pneumatic breaking system. The IR sensor is used to detect the
obstacle. There is any obstacle in the path, the IR sensor senses the obstacle and
giving the control signal to the Bumper Adjusting system.

2. INTRODUCTION
We have pleasure in introducing our new project “AUTOMATIC
BUMPER ADJUSTING SYSTEM”, which is fully equipped by IR sensors
circuit and Pneumatic Bumper 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.
The “PNEUMATIC BUMPER CIRCUIT” can stop the Opposite Running
vehicle. The intelligent Pneumatic Bumper system is a fully automation project.
This is an era of automation where it is broadly defined as replacement of manual
effort by mechanical 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 mechanical power
is required whereas in full automation human participation is very negligible.

3. WORKING OPERATION
The IR TRANSMITTER circuit is to transmitter 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 circuit receives the reflected IR rays and giving the control
signal to the control circuit. The control circuit is used to activate the solenoid
valve. The operating principle of solenoid valve is already explained in the above
chapter.

4. APPLICATION
• For automobile application
• Industrial application
ADVANTAGES
• Bumper cost will be less.
• Free from wear adjustment.
• Less power consumption
• Less skill technicians is sufficient to operate.
• It gives simplified very operation.
• Installation is simplified very much.
• To avoid other burnable interactions viz.… (Diaphragm) is not
used.
• Less time and more profit.
DISADVANTAGES
• Additional cost require doing the automation
• Free from wear adjustment
