1. PNEAUAMTIC OPERATED INTELIGENT BRAKING SYSTEM
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. 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.

is used to break the system
SCOPE OF THE PROJECT:
 We have pleasure in introducing our new project “AUTOMATIC PNEUMATIC
CLUTCH AND BRAKING SYSTEM”, which is fully equipped by IR sensors circuit
and Pneumatic breaking 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 BRAKEING CIRCUIT” can stop the vehicle within 2 to 3
seconds running at a speed of 50 KM. The intelligent breaking 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.
ADVANTAGES
 Brake 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

4.  Additional cost require doing the automation
 Free from wear adjustment
