2. • Car park barriers are the most common
method of managing traffic flow and parking
in busy or sensitive areas.
• Various boom barriers are primarily designed
to control traffic flow.
• Application ranges from private to
commercial including public car parks.
4. • Automatic detection of vehicle entering the car park.
• Automatic generation of ticket and lifting up of
entrance barrier & then lowering the barrier.
• For frequent users or staff, prepaid cards or tickets
have been provided and card reader machines are
placed at the entry point.
• Automated identification of ticket and lifting up of exit
barrier.
• Computerized computation of No. of vehicles in the car
park station and provides information about status of
car park station by showing ‘no space/available space’.
5. • Sensor (Ultrasonic transmitter & ultrasonic
detector)
• Microcontroller or Programmable logic
controller (PLC)
• Vehicle counter
• Barrier arms with motorized connection.
• Automated pay and ticket generation machine
• Central operation unit
6. • When a current flows through the solenoid of
valve, the piston in a cylinder moves upwards and
causes the barrier to rotate about its pivot and
raise to let a car through.
• When the current flow is stopped, the return
spring of the valve results in the valve position
changing back to its original position.
• When the current flows through another valve,
the pressure is applied to lower the barrier.
• Limit switches are used to identify whether
barrier is down or up.
7. • It is an automatic identification system.
• It consists of a RFID tags or transponders and a RFID
reader.
• The data or information about the vehicle is stored in a
RFID tag or transponder.
• The RFID tag can be affix or interpolated to a product
or vehicle for detection and tracking using radio waves.
• During the operation, these data has been retrieved by
the RFID reader.
• There are many different types of RFID systems in the
market. These are categorized on the basis of their
frequency ranges.
8. • A RFID system encompasses:
– An antenna or coil,
– a transceiver (with decoder) and
– a transponder (RFID tag) electronically
programmed with unique information.
