Abstract:

 

The solution has been provided for the problems encountered at BUSY Traffic signals using RFID technology.The software has been handled for controlling, the traffic.Radio-frequency identification is an automatic identification method wherein the data stored on RFID tags or transponders is remotely retrieved.RFID tag is a device that can be attached to or incorporated into a product, animal or person for identification and tracking using radio waves. Some tags can be read from several meters away, beyond the line of sight of the reader. RFID technology can be used in vehicle parking systems of malls and buildings.The system normally consists of a microcontroller, RFID Reader Module, display board and RFID tags.The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

INTRODUCTION:

In cities most of the vehicleS struck under the traffic by this they doesn’t went to their works properly for that purpose an advanced approach is required to detect the strength of the traffic before 500 mts.

By using RFID Technology we can detect the strength of the traffic and it is displayed on the lcd in a vehicle.

RFID Radio Frequency Identification technology has become one of the leading technologies in the modern world of communications with its utility in many areas of industry.

Any obstacle can be their infront of the vehicle sensors in the vehicle can detect the obstacle and displayed on the LCD display.

ARM-7LPC2148:

• The ARM7TDMI core is a 32-bit embedded RISC processor delivered as a hard macro cell optimized to provide the best combination of performance, power and area characteristics. •The LPC2148 microcontrollers are based on a 32 bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines the microcontroller with embedded high speed flash memory of 512 kB.• A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate.

• ARM stands for Advanced RISC machine. The first processor in ARM family was developed at Acorn Computers Ltd between October 1983 and April 1985.• The ARM core uses RISC architecture. Its design philosophy is aimed at delivering simple but powerful instructions that execute within a single cycle at a high clock speed.

ARM-7TDMI Features: 

32/16-bit RISC architecture (ARM v4T) 32-bit ARM instruction set for maximum performance

and flexibility 16-bit Thumb instruction set for increased code

density Unified bus interface, 32-bit data bus carries both

instructions and data Three-stage pipeline 32-bit ALU Very small die size and low power consumption Fully static operation Coprocessor interface

Features of LPC2148 Microcontroller :-

•16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.•8 to 40kB of on-chip static RAM and 32 to 512KB of on-chip flash program memory.• 128 bit wide interface/accelerator enables high speed 60 MHz operation.

•Single 10-bit D/A converter provides variable analog output.•Two 32-bit timers/external event counters (with four capture and four compare channels each), PWM unit (six outputs) and watchdog.•One or two (LPC2141/2 vs. LPC2144/6/8) 10-bit A/D converters provide a total of 6/14 analog inputs, with conversion times as low as 2.44 μs per channel.

•Low power real-time clock with independent power and dedicated 32 kHz clock input.

• Power saving modes include Idle and Power-down.

Software:EMBEDDED CEmbedded C is nothing but a subset of C language which is

compatible with certain microcontrollers.Some features are added using header files like <avr/io.h>,

<util/delay.h>.scanf() and printf() are removed as the inputs are scanned from

the sensors and outputs are given to the ports.Control structures remain the same like if-statement, for loop,

do-while etc. Keil compiler and proteous software are going to

be used.

ADVANTAGES:

•Gathering information through wireless technologies•Highly useful in traffic clearance and avoiding accidents•Can be used in ambulances•Accessible through world wideAPPLICATIONS:

•Commercial applications•Industrial applications•Bio-Medical applications•Wild Life monitoring and research

FUTURE SCOPEThe future implementation of this system can be

done through GSM (Global System for Mobile Communication) where communication media can be cellular.

CONCLUSION

•This project is a standalone intelligent transport system using RFID technology. • From the above discussion and information of this system, it can be concluded that it is highly reliable, effective and economical in urban, semi urban and also dense traffic areas. •Though it is not possible to install such system in all available vehicles, it certainly provides benefit to us and thereby to our nation.
