INTRODUCTION“CAN Based Accident Avoiding System”

PICTORIAL VIEW

What Is CAN Controller Area Network

Invented by Robert Bosch GmbH in 1980 for automotive applications

Asynchronous Serial Bus Simple 2-wire differential bus Absence of node addressing

• Message identifier specifies contents and priority• Lowest message identifier has highest priority

Non-destructive arbitration system by CSMA with collision detection

Multi-master / Broadcasting concept Sophisticated error detection & handling system

ULTRA SONIC SENSOR

• KIEL Micro Vision4.

• LPC flash utility

SOFTWARE USED

16/32-bit ARM7TDMI-S microcontroller in a 64 or 144 pin package. 16 kB on-chip Static RAM. 128/256 kB on-chip Flash Program Memory. 128-bit wide interface/accelerator enables high speed 60 MHz operation. Two/four interconnected CAN interfaces with advanced acceptance filters. Four/eight channel (64/144 pin package) 10-bit A/D converter with conversion time as low as 2.44 ms. Two 32-bit timers (with 4 capture and 4 compare channels), PWM unit (6 outputs), Real Time Clock and Watchdog. Multiple serial interfaces including two UARTs (16C550), Fast I2C (400 Kbits/s) and two SPIs. On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz

FEATURES OF LPC2129

ULTRASONIC SENSOR

•With 2.5V - 5.5V power the ultrasonic provides very

short to long-range detection and ranging, in an

incredibly small package

• The LV-MaxSonar-EZ1 detects objects from 0

inches to 254-inches (6.45-meters) and provides sonar

range information from 6-inches out to 254-inches

with 1-inch resolution.

FEATURES OF ULTRASONIC SENSOR

Minimum range 10 centimeters

Maximum range 650 centimeters (6.5 Meters)

Accuracy of +-1 cm

Resolution 1 cm

5V DC Supply voltage

Compact sized SMD design

Modulated at 40 kHz

Serial data of 9600 bps TTL level output for easy

interface with any microcontroller

•Multiple operations can be performed

•Centralize control

•High accuracy

•Very high level of security

•Error detection and error signaling

ADVANTAGES

Used as a Warning System to avoid Collision in National Highways.

Used by Police to Track the speed of the approaching vehicles.

Used to detect an object in Extreme conditions like Fog and misty areas.

Can be implemented in Robotic Applications.

Can be used in large vehicles like Trucks and buses

Can be implemented in Aircraft and aerospace electronics

Can be used in Passenger and cargo trains

Can be implemented in Maritime electronics

APPLICATIONS

Any Quarries?
