Abstract — Desaturation Protection MATLAB

stacks, simulation worlds, reports and viva from Bangalore. This paper proposes, designs and constructs an image recognition & voice technology based security system by highlighting the advantages of image processing technology and voice synthesis technology which are presence in the electronic market.

Analytical & State-Space Control Methodology

This paper mainly approaches towards enhanced security by checking the tag image of the operator as well as recognizing voice which are validated previously by this system just using simply a web-camera or closed circuit television (CCTV) camera and a voice recording software system and gives the signal in terms of alarm, Alert Light, message via global system for mobile communication (GSM)/ general packet radio service (GPRS) to the consumer mobile number/the nearest police station’s mobile number.

Simulink Waveforms & Power Quality Findings

Keywords: Closed circuit television (CCTV), Light dependent resistor (LDR), Short message service (SMS), Synthesis, Two dimensional discrete cosine transform (2D-DCT), Figure 1: Power Converter Circuit Schematic & Electrical Interfacing for Desaturation Protection Matlab An outlying home security, supervision and protection system have become more and more desirable with the progress of IT technology, network and automatic control technology now-a-days. Wireless sensor network (WSN) and global system for mobile communication (GSM) technology provide a better design and development of remote home security and supervene system whose main goal is to identify theft, fire etc., and send SMS to the respective house owner’s mobile phone . By visualizing home safety status on the controller desktop, laptop, PDA, mailing address or mobile phone, the user is always notifying with the current view of home. However, appropriate development of this method provides justification of the current safety level as well as to make summary judgment of home safety . The need of security system is essential to make safety against crime and burglary acts that are the common issues now-a -days. Till now, a number of solutions on home security system are developed and some are implemented successfully in the market but most of these are either highly expensive or have lack of pleasant security. For example, “Wireless home network using 802.11 technology” in paper suggests a wireless home network security known as Wi-Fi security system, which provides a medium for transferring media files. However, it is highly expensive and power consumer. “Security system against asset theft by using radio frequency Identification Technology” and “Positioning and tracking construction vehicles in highly dense urban areas and building construction sites” both papers highly represent, graphical user interface (GUI), is used in vehicle security system where the information is controlled via the GUI [4, 5]. The system is activated when the tag image is read while the motor cycle is being located within the effective range. It’s also highly expensive and power consumer.
