Objective :- :-
The objective of this project is to
monitor the vehicle parameters such as speed, traveled distance, fuel level,
engine temperature and mileage.
Scope
Normal existing meter are Analog meter. The
one draw back in this meter are we cannot know that exact fuel quantity in the
tank but in this project the exact quantity is displayed in the digital form
and also speed of the vehicle and how much distance the vehicle has been
traveled like these information also displayed. We can also monitor the engine
temperature.
Brief Methodology
This project is designed with
- Float sensor
- Microcontroller
- LCD display,
- ADC
- Proximity sensor
- Amplifier unit
- Temperature sensor
- Driver circuit with alarm
In this project proximity sensor is fixed in
the wheel. When the wheel is rotating the proximity sensor gives the pulse to
the micro controller. Inside the counter will count that pulse from this we can
easily calculate the revolution per minute (RPM). If you multiply into hour we
can calculate the revolution per hour by which we can measure speed of the
vehicle.
If we know the Diameter of the
vehicle we can measure the Distance that the vehicle has been traveled. The
fuel storage in the tank is monitoring by float which is fixed in the tank and
connected to microcontroller through amplifier and ADC.
Float sensor is nothing but transducer
which generates the voltage signal depending on the fuel level in the tank.
These signals are in the range of milli volts. So the transducer output is
given to amplifier circuit to amplify the signals. The amplifier circuit consists of operational
amplifier. The amplified signals are
given to ADC.
Similarly the temperature sensor is used
to monitor the engine temperature. The temperature sensor output is given to
microcontroller through amplifier and ADC.
ADC is nothing but analog to digital
converter. It converts the incoming
analog signals into corresponding digital signals. The converted digital signal
is given to micro controller. The microcontroller
is the flash type reprogrammable microcontroller in which we have already
programmed with our objective. The
Microcontroller received those digital output signals from ADC and compared
with stored value. So now we knew distance and fuel used by the vehicle from
which we can measure the mileage of the vehicle and projected mileage for
remaining fuel in the tank.
The corresponding all measured values are
displayed in the LCD display such as speed, traveled distance, fuel quantity
and engine temperature and mileage. If speed or engine temperature is above
normal value as well as the fuel quantity in tank is low level, the
microcontroller activates the alarm driver circuit.
Advantage
1. This
project used to monitor the fuel quantity, speed, distance and engine
temperature.
2. All
measured values are displayed as the digital value in the LCD display. So we
can easily viewed.
