This document describes a road accident avoiding system using a drunk driver sensing technique. The system includes a controller, switches and sensors, relays, and motors. The controller is programmed to control the vehicle's functions. A drunk sensor detects if a drunk person is in the vehicle and sends a signal to the controller to stop the DC motor and vehicle via relays if a drunk driver is detected. The system aims to reduce accidents by automatically stopping a vehicle if a drunk driver is sensed.

ROAD ACCIDENT AVOIDING SYSTEM BY DRUNKER
SENSING TECHNIQUE
ABSTARCT:
Mechanical engineering without production and manufacturing is
meaningless and inseparable. Production and manufacturing process deals
with conversation of raw materials inputs to finished products as per
required dimensions specifications and efficiently using recent technology.
The figure shows the block diagram of controller based Drunker
Sensing Vehicle. This system is equipped with drunker sensor to identify
the Drunker Person in the Vehicle and Stop the Vehicle.
The block consists of switches and sensor, controller, relays and
motors. The Required Actions of vehicles are First Programmed and is
Stored in controller. So we can get Signal from controller Only.
Start Button is used to start the operation of the vehicles. We can
Press the Start button and then vehicles action can perform. Drunker Sensor
is used to Sensing for Drunker Person in the Vehicle. controller reads the
Input Signals and it can produce the output according to the Assembly
language program stored in it. The output Signals to drive the DC motor is

2. used to Forward & Reverse Direction using relays & relay and then the
vehicles action can perform like forward and reverse
If
any
Drunker
Person is occurred, the controller Stop the DC Motor using relay driver and
relay. In this way can Drunker Person in Vehicle using controller.
