FIELD PROGRAMMABLE GATE ARRAY
Nios development board Cyclone II edition(C language)Wired and wireless motion sensorsMemory Management UnitCustom peripheralsControllable home appliances and devices such as
refrigerators, air conditioners, fans, lights, motion detectors, smoke detectors and so on
Socket programming, HyperText Markup language (HTML), cascading style sheet (CSS), Javascript and personal home page (PHP) are used to develop the user interface
Overall System
FIELD PROGRAMMABLE GATE ARRAY
The Nios II board is factory programmed with a reference design that implements a web server.
A host computer is connected to the board's Ethernet port, assigning an IP address to the board and helping with browsing the web server from the host computer.
In order to function on a network like local area network (LAN), the board must have an IP address.
Obtain a dynamic IP address using dynamic host configuration protocol (DHCP) or a static IP address stored in flash memory.
The Nios II development flow is comprised of threecategories.
1 )Hardware design steps; 2 )Software design steps;
3 )System design steps

• Backbone of entire system• Server serves webpages for
direct communication between user & system
• HTML-Markup of page• CSS- layout & style• PHP- communicate with
server to send mails to user• Javascript-advanced parts
• Create a web server that can provide web pages to a browser;
• Design and implement the web pages for the browser
• Add capability to control output pins from the web pages
• When the inputs are triggered, automatically update web pages.

FIRE AND INTRUDER ALERTING
The fire accident that can happen in home during the absence of the resident and, intruder making unauthorized entry into the flat should be alerted and intimated to a remote location.
Following actions are taken1. occurrence fire in home or, detection of intruder by a sensor is detected electronically. 2. It is then sent as SMS and then converted into email and sent again to a remote PC. 3. remote PC executes a file to create an alarming sound. The email can also be received in a cell phone causing a beep sound
FIRE AND INTRUDER ALERTING
FIRE AND INTRUDER ALERTING
WORKING of System If excessive light or heat is sensed electronically in
the flat and if any of its voltage exceeds the threshold then it interrupts the microcomputer.
The interrupt service sends a text message to GSM module which in turn sends an email to the specified email-id.
This email message can be received in an internet backed PC.
the email platform is set up with a specific word in the text, the exe file would run a set of instructions as to give alarming message.
The email can also be received in a cell phone causing beep sound alerting the user.
Fire Detector Actuated Telephone Dialing and Response
Heat or light is sensed electronically and comparing with a threshold.
An electronic dialing circuit attached to home telephone can be triggered by signal obtained from any type of detector circuit.
it operates a relay circuit so as to receive dial tone and to commence dialing.
it sends signal to a sequential logic circuit that injects the series of pulses corresponding to chosen digits into the telephone lines.
It will dial the digits of resident’s mobile number whenever fire detector is activated.
A relay circuit is switched ON so as to operate a solenoid valve triggering a fire extinguisher electromechanically.
The fire extinguisher can be set to operate manually also.
Why is a webpage preferred over customised GUI in FPGA?
1. Eliminates hassle and inconvenience of installing
program
2. Quicker, easier, cost-effective to Update & make
changes
3. Marketable
Advantages of FPGA and GSM
1. Real time home security monitoring
2. Remotely controlled home appliances
3. Accessibility (remote location –SMS/mail)
4. Reliability
5. Low cost
6. Low power consumption
7. Secured with a login password
8. Monitored systems
Disadvantages of FGPA & GSM
1. Password can be hacked
2. Webpage refresh rate is 10sec
3. Compulsory internet or SMS connection is
required
4. Just monitoring and image capture of
intruders
5. Batteries have to be replaced
6. Monitored systems normally are not sold
separately
Future scope and alternatives
Development of biometric sensorsSmart surveillance cameraMore mainstream
