Radio frequency based real time Child Monitoring and alarm system


INTORDUCTION
Background
The Child Monitoring System is a system which is developed using RF technology to monitor child in a certain area. The system is separated into two parts. This thesis will concentrate more on parent s part while the thesis on child s part will be concentrated by other person. Parents have the master device while the child has the slave device. The master device is sending and recei ....etc

Design and Application of Radio Frequency
Identification Systems

Abstract

The recent world, development of effective technologies for linking the object
wireless information is being prompted in various fields. Radio frequency identification
(RFID) is the latest technology for automatic identification which allows the transmission
of a unique serial number wirelessly. The purpose of this paper is to review RFID systems
and its various components infrastructure. The components and features are still under
research and b ....etc

1. ABSTRACT
RF communications find great applications in our daily. It has got increased priority in security systems, communications, automations etc. The proposed project is a RF based child monitoring system which is practically reliable and easy to install. Radio Frequency based real time Child monitoring and alarm system helps in monitoring the child by the parents. The device monitors the child and produces an alert signal when ever the child passes a certain distance i.e. for instance the system can be des ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

pOWER TRANSMISSION THROUGH FRACTIONAL
FREQUENCY SYSTEM


ABSTRACT

The fractional frequency transmission system FFTS is a very promising long -distance transmission approach, which uses lower frequency (50/3) to reduce the electrical length of the AC power line, and thus its transmission capacity can be increased several fold . This paper introduces the primary experiments results of FFTS.

The experiment uses the phase-controlled cycloconverter as the frequency changer, stepping up 50/3Hz electricity to 50Hz electricity and ....etc

Power house Monitoring
Power house monitoring is done on the receiver part fitted with lcd.Following parameters monitored are ,high voltage,over load, novoltage or temperature high.,these paremeters are transmitted by transmitter .audio and visual alarm comes on both the places ,alarms have to be reset from both the places.receiver will also display the alarming condition.these conditions also logged on to pc through serial port. ....etc
