Microcontroller Project Report on Aeronautical Crash Prevention System through RF Communication

Introduction Micro controller Project Report on Aeronautical Crash Prevention System through RF Communication:

The main objective of this paper is to prevent collision of aircrafts. Here communication is done through RF. RF is preferred due to its features like high Bluetooth range and can detect long distance objects and which are travelling at all sides of the main object. This system consists of microcontroller, LCD, buzzer, transmitter/ receiver, Encoder/Decoder, power supply.

Brief into design and working :

In this system the design involves two sections namely transmitter and receiver section. In the transmitter section, microcontroller generates the parallel data and is encoded, and then the parallel data becomes serial data after encoding and is transmitted through RF transmitter. In receiver section, the receiver receives the transmitted serial data and decodes the serial data into parallel data by using the decoder and is given to microcontroller.

The microcontroller takes the action and status is displayed in the lcd and the buzzer starts initially. Coming to working of this system, each and every aero plane consists of both transmitter and receiver. Every aero plane has an specific IP address. The transmitter keep on transmitting the ip address and if any aero plane is found near by then the receiver receives the ip address of aero plane nearby.

If the receiver receives the information about other aero plane that means it is within the range of hundred meters. Then the status is displayed in the LCD and the buzzer starts .So, when the buzzer starts and status is displayed we can divert the planes without colliding.

Electronic Temperature Controlled Relay Project Report

Introduction to Electronic Temperature Controlled Relay Project:

The main objective of this paper is to develop a simple circuit which can control temperature. In our day to day life, We come across many devices whose temperature has to be maintained. If the device crosses temperature specified then it leads to many problems.

In order to avoid these problems, device has been developed to control temperature. By using this the temperature can be controlled .This circuit consists of comparator, temperature sensor, reference voltage ,relay and printed circuit board.

Brief into Design and working     

The temperature sensor LM35 is used, it senses temperature comparator used acts as a thermal controlled switch. Reference voltage is used to maintain constant voltage even though there are fluctuations in voltage. Relay is used to control the circuit by one signal. Printed circuit board is used to connect components using tracks.

The working of this circuit is as follows. First, temperature is presented. The temperature sensor senses the temperature and if the temperature is above the one which is stored, then relay is actuated and is temperature is controlled.

If the temperature is less than the stored one, then relay is turned off. One of the best practical examples is controlling the temperature in water tank with a heater whose temperature can be set to a particular value.

As the technology is advancing we can add some of the additional benefits like buzzer to give a sound when the temperature is high and gsm technology which can send information to specified person automatically.

Adaptive Equalizer For Digital Systems

Introduction to Adaptive Equalizer For Digital Systems:

This project aims at reducing the effects caused due to multi paths in mobile communications. In non line sight communication the signal does not go in a direct path and it gets effected due to various factors as it under goes deviation. We propose adaptive equalization method for the reduction of multi path signals at the receiver. In this paper we will discuss the working model of adaptive equalizer.

Brief into working of adaptive equalizer:

Due to deviation in the signals the multiple copies are signals are received at the receiver so it becomes difficult to trace out the original signal, by which the accuracy of the signal gets reduced. By using an adaptive equalizer the received signal can be nullified so as to reduce the noise components. Channel response at the receiver is estimated by using a pilot carrier or a training sequence. Approximation inverse filter is used to isolate the distortions occurred in the signal. A matched filter is used to boost up the signal as it undergoes through various processes. Adaptive filter is always inserted in front of the channel so as to compensate the signal. To make the incoming response equal we will use a feedback supply for the channel.

Advantages:

By employing adaptive equalizer the accuracy of the system gets increased.  As the original signal can be traced easily we can increase the quality of the signal. This is an efficient technique for reducing the effects due to scattering and distortions. Thus we can conclude that adaptive equalization technique is the best method to overcome the multipath signals in mobile communication

Generation of PN Sequences for Spread Spectrum Application ECE Project Abstract

Introduction to Generation of PN Sequences for Spread Spectrum Application ECE Project:

Introduction to spread spectrum:

Spread spectrum is an signal structuring technique which employs a frequency hoping of direct sequence for achieving multiple access of signal in telecommunications. We will employ frequency hoping spread spectrum(FHSS), direct sequence spread spectrum(DSSS), time hoping spread spectrum (THSS) and chip spread spectrum(CSS)  for generating pseudorandom of PN sequences. In this paper we will discuss the generation of PN sequences using spread spectrum.

Brief about spread spectrum:

By spread spectrum technique the signal is spread in frequency domain which generates a signal with higher bandwidth. For applying the spread spectrum a direction sequence signal is taken so that the signal can be used for multiple access and this decreases the potential difference at the receivers. At the receivers the original signal is retrieved. Pseudo random generators are used for generating pseudo random for the PN sequence. Radio signal is used for generating a wider signal using spread spectrum for the direct sequence signal. In synchronous digital systems spread spectrum clock generators are used to reduce the spectral density of the electronic interference generated in the system.

Applications:

The spread spectrum is widely used for increasing resistance to a natural interference and to reduce the usage of power flux density. These are mainly used in communication in satellite downlink channels.  By using spread spectrum the noise in the signals can be isolated completely.

The drop bolts are placed in the locker an a electronic switching device (Relay drivers) are connected to these bolts. The signals from the host computer to the these switching devices are carried out with an RS232 cable. The application software checks the entered details and verifies them and allows the use to access the locker. A secure messenger application is used to decrypt the data for the mobiles. The system is provided with back-up power supply to avoid break downs. The entire application is developed on java platform.

Applications and Future scope:

These type are lockers are very useful in providing security, and these lockers are controlled automatically which reduces man power. But the is a drawback that an person can open the lockers by giving the user id and password , as the system does not know whether is a right person or not. This can be overcome by making the authentication process with finger print scanner or an eye scanner, where these is no possibility of manipulating. Thus we can conclude that electronic locker systems are very useful in the modern days.
