Laser Led Based Voice Communication System ECE Project Abstract

Introduction to Laser Led Based Voice Communication System Project:

In past radio frequency signals are the mere source of data transfer but due to improved technology in communication fields recent times created new dimensions in the field of wireless communication. Any electrical and electronic system is operated without the involvement of the wired connections (conductors) are termed as wireless,

In our project laser/led based voice communication system we discuss briefly about designing of the proposed circuit, and develop new ideas in this concerned field, we provide the detail study of the entire circuitry and different types of components used in this circuit.

The active medium in this process is the laser which is the main source for the transmission of the information the choice of laser should have the following properties like; I should be highly monochromatic and coherent.

 This paper describes about two major units one is transmitter unit and the second is receiver unit, the transmitter modulate the signal into optical signal with the help of lasers and transmits the signals through air, and in the receiver section a highly-sensitive receiver is employed for speech bandwidth modifications which decodes the optical information into required audio signal by the help of audio amplifier and photo transistor.

This photo transistor gains information from the light signals and feeds to the amplifier which amplifies the signal and passes to the speaker, the complete circuit description and its operation along with modified results are mentioned in this paper.

While considering the advantages this system is very improved in the areas like maintaining secrecy, high audio quality, privacy in communications is facilitated by using automatic sensor systems, this technique is adopted for interior or exterior communications over a wide range of distances.

The research on laser applications in the field of wireless communications paved path for the advancement in the free space optical communication to a great extent.

JNTU Mini Project for ECE on Mobile Controlled Devices with Project Report

Introduction to  Mini Project on Mobile Controlled Devices with Project:

In this project we designed a system which use sour mobile phone(DTMF)Dual Tone Multi Frequency technology  Every mobile phone has this facility. In this present technology we have a challenge of long distance computer communication, this can also referred as information networks.

For exchange of information we have many information services in present days like Video teleconferencing,Telex, Facsimile transmission (FAX), Electronics mail, which are much efficient to transfer the information but are expensive too. Our project Mobile Controlled Devices designed by us comes into picture when all the technologies fail when the situation comes to upload or terminal download of files or information fails from the mains.

Use of RF circuits in wireless controlled devices have the drawbacks of limited frequency range, limited working range,limited control options and limited features.To overcome all these above mentioned limitations, our designed device is operated using a mobile phone so that this device can be controlled from anywhere in the world and also gives the advantages of more control options other than device control, no interference as the telecom network has the fixed bandwidth with other signals and if the coverage area of telecom network is good depending on this the working range of the device is unlimited. In our device we can adopt 12 different control options as from any mobile or land line phone, by activating the mobile keypads different keys 12 different DTMF codes will be generated.

Mobile phones or cordless phones are suites best for this application, which use 8870 chips for design.Our designed device in the project working principle is that the device receives the command signals through the mobile phone, the switching of devices will be controlled according to the remote end control signals received through another mobile by decoding the cordless phone DTMF signals received.

ECE Industry Mini Project Report on Power Supply Scheme of BEL

Introduction to Mini Project Topic on Power Supply Scheme of BEL:

BEL- Bharat Electronics Limited, Machilipatnam is established in the year of 1981 become an India mart member since from 2011. It is a manufacturer company expanded their business in the Indian subcontinent and nearly 500 people employed in it.

There is a requirement for energy management means usage of fewer amounts of energy resources or fossil fuels as we have limited energy resources. People in all over the world has been realized the importance of energy management as we have limited fossil fuels and there is an increase in demand. Energy management and energy efficiency place a very important role in saving the energy.In transmission and distribution of power, power factor plays a major role that is how means if the power factor is low then that system draws more current to satisfy the connected load for a given amount of power. There are two Power Factor Control Centers (PFCs) in BEL to correct low power factors.

BEL-MACHILIPATNAM is having 11KV/440V substation to take care of loads inside the factory and for stepping down the voltage levels BEL-MC has two 750KVA on-load transformers. The incoming main supply 11KV at BEL-MC is divided into 2 feeders to connect to these two transformers through Gang Operating Switch (GOS).

BEL-MC has many energy consumption areas and has a11KV/440V substation. Through this substation only the electric power generated from the APSEB is distributed and Power Control Center controls the power distribution throughout the plant. For any power supply failures BEL-MC consists a backup of 750KVA DG-set.This substation contains one power control center, two 750KVA transformers and one diesel generator.

This paper gives detailed information about the substation, energy consumption pattern in the BEL-MC and the concepts of Energy Conservation and Energy Efficiency that how BEL-MC fallow and satisfy the energy conservation methods.
