INTRODUCTION
This project is an advanced device for the toll collection in the highways .
This project is an advanced device for collecting the taxes of vehicles easily
and very effectively .
This project is an device which not only for toll collection we can use for alcoholic detection also
Major advantages of PSoC controller
There is no other microcontroller that has programmable voltage
Hardware generators of pseudorandom and CRC code as well as
analog modulators are unique to this families
MAC (Multiply-accumulate) is an essential part of digital signal
processors
Option for low voltage supply (~1V) is a tremendous advantage
in battery -operated systems.
Timers, counters, and PWM units are more flexible than the usual implementation.
Automatic code writing for accessing all the peripherals in use.
BLOCK DIAGRAM DESCRIPTION:
PSoC : Programmable System on Chip
PSoC (Programmable System on Chip) represents a whole new
concept in microcontroller development. Consist of 8-bit
Microcontrollers.
Characteristics of PSoC microcontrollers
MAC unit, hardware 8x8 multiplication, with result stored in 32-bit accumulator,
Changeable working voltage, 3.3V or 5V.
Possibility of small voltage supply, to 1V.
Programmable frequency choice.
Card reader (RFID)
RFID stands for Radio-Frequency Identification.
Small electronic devices that consist of a small chip and an antenna.
The chip typically is capable of carrying 2,000 bytes of data or less.
The RFID device serves the same purpose as a bar code or a magnetic
strip on the back of a credit card or ATM card; it provides a unique
identifier for that object.
Display (LCD)
A liquid crystal display (LCD) is a thin, flat panel used for
electronically displaying information such as text, images,
and moving pictures
keypad
Keypads are a part of HMI or Human Machine Interface and
play really important role in a small embedded system where
human interaction or human input is needed
ALCHCOL DETECTION USING PSOC
The Automotive Coalition for Traffic Safety and the National
Highway Traffic Safety Administration have entered into a
cooperative research agreement to explore the feasibility,
the potential benefits of, and the public policy challenges
associated with a more widespread use of in-vehicle
technology to prevent alcohol-impaired driving.
Almost 9,000 road traffic deaths could
be prevented every year if alcohol
detection devices were used
in all vehicles.
SENSOR
A sensor is a device that measures a physical
quantity and converts it into a signal which
can be read by an observer or by an instrument.
LCD (DISPLAY)
It is a thin, flat panel used for electronically displaying information
such as text, images, and moving pictures. Its uses include
monitors for computers, televisions, instrument panels.
ADVANTAGES (automated toll collection)Toll Lane Capacity
Vehicle Waiting Times
Reduction of Toll User Costs
Simplified Infrastructure and Accounting System
Toll Agency Costs
User Costs
DISADVANTAGES
Payment Enforcement
Legal and Technical Criteria for Payment Enforcement
Automatic Vehicle Classification (AVC)
ADVANTAGES (ALCOHOLIC DETECTION)
Almost road traffic deaths could be prevented every year alcohol detection .
Safety is more .
Traffic jamming will be prevented because of no accidents .
DISADVANTAGES
Expensive (in the sense cost is more)
If we cannot wipe properly its shows wrong results
