 Brief Methodology

        This project is designed with microcontroller, Ultrasonic Transmitter, Receiver, Signal conditioning unit, Analog to Digital converter, Driver Circuit and Mechanical arrangement.

        The oscillator circuit generate 40KHZ frequency signal. It is transmitted through ultrasonic transmitter. The ultrasonic receiver is used to receive the reflected wave due to in front of the vehicle. Then the reflected wave is given to signal conditioning unit in which the incoming wave is amplified and converted into square pulse. Then the square pulse is given to ADC. Depends upon distance the reflected wave strength is varied.

        ADC is nothing but analog to digital converter, which converts the input analog signal into corresponding and digital signal. This digital signal is given to microcontroller.

        The microcontroller may Atmel or PIC both are flash type reprogrammable microcontroller in which we have already programmed. So it received the signal from ADC displayed on the LCD display. This is equal to distance between the vehivle and front side object. The object may vehicle, trees or road barriers. Nearest dangerous distance value is already stored in the microcontroller. When measured distance is reached this value, microcontroller automatically activates the relay driver circuit. The relay output is directly connected to mechanical arrangement. Through this mechanical arrangement braking is provided and vehicle is stopped in order to avoid the accident.

Block Diagram: - Automatic Filling System

 Introduction

        This project is designed with micro-controller, Real time clock, Relay driver circuit along with relays, Keypad and Mechanical arrangement.

        Real time clock is the special type to IC integrated circuit used to generate real timing signal. It is generally called as RTC. Battery is in build in this IC. Even though power is switched OFF, it can maintain the timing signal. RTC sends the timing signal to micro-controller.

        Here the micro-controller may Atmel or PIC both are flash type reprogrammable micro-controller in which we have already programmed. The set of keys in the keypad is used to set the time of operation.

        For an example if you want to cut the material for an hour the timing is set in the microcontroller through the key bad. The microcontroller receives the timing signal from RTC, and activates the relay driver circuit for that particular time period. The relay output is directly connected mechanical arrangement. This mechanical arrangement is designed to be fit the different hack saw such as slanting teeth, sharp teeth etc. So the cutting operation is performed for that particular time period. At the end of the setting time, microcontrollers turn OFF the relay so the cutting operation is stopped. Through this way cutting operation is performed automatically.

Car Theft Prevention Using Code Locking System

 Aim :- :-

        The aim of this project is to detect the theft of a vehicle and alert the user and to prevent the vehicle from theft by disconnecting the petrol tank connection at emergency situation automatically.

Project Description:-

            Nowadays the car theft is a huge criterion for the car owners. Even though the manufacturers provide car security system, but the car thieves easily break those systems. So, we plan to prevent the car from the thieves using FUZZY LOGIC.

       In this project, the car could be started only when the given password is correct. We use a 4x4 matrix keypad to feed the password. The LCD display is used for displaying purpose. The micro controller is the heart of the project, which controls the whole system.

        The micro controller is interfaced with the keypad, LCD display EEPROM, petrol tank and battery control circuitry. The password is stored in the EEPROM. The EEPROM is used because the stored password can be electrically erased and could store another password if necessary.

       While starting the vehicle, the password should be entered. If the entered password matches with the stored password, the petrol tank is opened and the battery control circuitry is switched ON. The micro controller is programmed to perform all those operations.

       But if the entered password mismatches, then the micro controller will not allow the petrol flow and also will not switch ON the battery circuitry. Hence, our circuit provides a guaranteed security to the car or vehicle using this system.

Embedded Digital Dash Board

 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.
