CONTENTS INTRODUCTION MAJOR COMPONENTS MICRO CONTROLLER RFID GSM PROJECT EXPINATION APPLICATIONS CONCLUSION
INTRODUCTION • For today’s transportation professionals , traffic management, safety and security initiatives are an increasing priority. • State and local agencies are searching for solutions to improve mobility, efficiency and safety of their operations for the driving public. • Current transport facility is suffering with many issues. Accident risk management Traffic rule violation control Traffic signal management • RFID TECHNOLOGY can be effectively used to solve some of them
MAJOR COMPONENTS • Some of the major components are using to develop the projects Power supply Micro controller RFID GSM
POWER SUPPLY • A power supply is a device that supplies electric power to an electrical load. • Basic power supplies can normally be divided into 4 parts. The Transformer The Rectifier The Filter and in some circumstances The Regulator
THE TRANSFORMER • A transformer is an electrical device that transfers energy between two circuits through electromagnetic induction. • A transformer may be used as a safe and efficient voltage converter to change the AC voltage at its input to a higher or lower voltage at its output.
THE RECTIFIER • A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current(DC), which flows in only one direction. The process is known as rectification. • A diode bridge is an arrangement of four diodes in a bridge circuit configuration that provides the same polarity of output for either polarity of input.
FILTERS • Electronic filters are analog circuits which perform signal processing functions, specifically to remove unwanted frequency components from the signal, to enhance wanted ones, or both. • TYPES ACTIVE FILTER PASSIVE FILTER
REGULATOR • A voltage regulator is designed to automatically maintain a constant voltage level. A voltage regulator may be a simple “Feed-forward" design or may include negative feedback control loops. • It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.
SPECIFICATIONS •4 KB on chip program memory. • 128 bytes on chip data memory(RAM). • 4 register banks. • 128 user defined software flags. • 8-bit data bus • 16-bit address bus • 32 general purpose registers each of 8 bits 16 bit timers • 3 internal and 2 external interrupts. • Four 8-bit ports, • 16-bit program counter and data pointer. • 1 Microsecond instruction cycle with 12 MHz Crystal.
RFID • RFID stands for radio frequency identification • radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects • Frequency for RFID uses 433Mhz for short range devices
WORKING OF RFID
• GSM STANDS FOR GLOBAL SYSTEM FOR MOBILE • GSM modem is a device that modulates an analog carrier signal to encode digital information and demodulates the signal to decode the transmitted information. • The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. • Modems can be used with any means of transmitting analog signals, from light emitting diodes to radio
• Each and every RFID tag has a unique identification. • These RFID tags are attached to every vehicles and one RFID reader is to fixed at one side of the road near junction. • If any vehicle crosses the signal then active RFID tags are detected by RFID readers and that vehicles information will be sent to nearest control room through GSM modem
APPLICATIONS • SOME MORE APPLICATINS BY USING RFID TECHNOLOGY Congestion detection & management scheme intelligent traffic-light Finding thieves and offenders public parking
CONCLUSION • In our country that is going to become an electronic government to applicant this plan can have important effect on electronic government and electronic city and optimize traffic moneymen and country transportation system by information and communication technology application
