AIM:
The main aim the project is to design “DEVELOPMENT OF ADVANCED EMBEDDED SYSTEM FOR ACCIDENT AVOIDANCE SYSTEM”.
COMPONENTS:
S3C2440 (ARM9)/LPC2148 (ARM7)/ AT89S52, IR transmitter and Receiver, LCD , Motor and buzzer.
EXISTING METHOD:
In the existing method it is just used to detect the obstacles and gives indication to the person inside the vehicle through buzzer sound as an indication. But with the growth of vehicles in large number and with the same Narrow size road it is very difficult for the driver to drive a vehicle safely without a crash on the road even though a buzzer sound indication is given. If for a small fraction of time if a vehicle driven has missed his attention then it will result in crash of vehicle with front vehicle even if the vehicle is in small speed or no speed. In congested traffic sometimes a vehicle owner gets frosted on hearing the buzzer sound continuously and he can’t keep watch on vehicle in slow moving traffic.
PROPOSED METHOD:
In our proposed system we are using an Infrared transmitter and infrared receiver combination system which is attached to a microcontroller board. Motor is attached to a microcontroller based embedded board. The IR sensor system continuously sends signals and monitors any car or other obstacles are in front of car. The distance up to which IR sensor can work may be up to 1 meter. When any obstacle or vehicle detected by IR sensor system it will send signal to the embedded board. After receiving this signal embedded board sends a signal to the motor to stop the car automatically which stops immediately. Vehicle is controlled automatically without any manual operation when the vehicle is at 1 meter distance away from the front vehicle.
The system uses a compact circuitry built around S3C2440 (ARM9)/LPC2148 (ARM7)/ 8051 microcontroller Programs are developed in Embedded C. Flash magic is used for loading programs into Microcontroller
