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
SYSTEM WITHOUT CAN
SYSTEM WITH CAN

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?
