Abstract-The internet enabled devices for remote

control and remote monitoring are becoming popular

now days, the use of Ethernet for the connectivity for

the appliances is increasing, so the challenges for the

embedded designers are to add more functionality

without increasing the cost and size of the product.

This paper presents the approach for developing an

automation system that can remote monitor and remote

control the appliances through the use of embedded web

server with SoC platform via home area network or

internet.

The system can control the fan motor light & other

electrical appliances also acquire & monitor sensors

data to know the temperature & humidity. Advantages

are low cost, light weight & reliable.

Key words: Arm9, BOA web server, TCP/IP, CGI.

I. INTRODUCTION:

Focusing on the autonomy of the people over the

age of 65 having the disabilities, this paper represents

a web server to monitor and control data in home area

network. Now a day’s internet enabled devices are

becoming very popular, on the same technology we

are going to implement TCP/IP web server system

which acquires and monitors the data and provides

control over the devices [6].

Needs of high speed, bandwidth, economy,

compatibility, are satisfied by the Web server system

using TCP/IP. For this, interface design is the main

issue, web pages provide the interface to the

embedded server system.HTML (hypertext-markup-

language) pages and web server software is the need

of embedded system [6].

TCP/IP allows the different computing devices to

access the web page which provides greater security,

the user can browse web page from different area

using the home area network/internet.

The purposed system provides control over,

Control of home appliances.

Measuring of sensors data

Monitoring of live status of devices.

II .RELATED WORK:

It is noticed that, works on home automation for

people disabilities are specific, usually on single type.

This wok focuses on elderlies, visually impaired

people, hearing impaired, people with motor

impairment & cognitive disabilities ([5]-[7]).

The project assistive housing focuses on elderly

comfort uses television set and remote for home

automation. To improve legibility& accessibility

large icons along with captions were used,. in that

numbers are used as a shortcuts to interact with user

& navigation is avoided [7].

III. PROPOSED METHODOLOGY:

3.1 Hardware Details:

Its hardware details are Samsung S3C2440 with

ARM920T RISC technology which is 32 bit also

provides an Ethernet controller DM9000 and audio

codec UDA1341TS which are useful for this paper

[19]. Ethernet controller: The DM9000 is a fully

integrated and cost-effective single chip fast Ethernet

MAC controller with a general processor interface, a

10/100M PHY and 4k Dword SRAM. It is designed

with low power and high performance process [19].

Page 2: Building a TCP/IP Web Server System to Acquire and Control Data …ijsetr.org/wp-content/uploads/2014/12/IJSETR-VOL-3-ISSUE... · issue, web pages provide the interface to the embedded

International Journal of Science, Engineering and Technology Research (IJSETR), Volume 3, Issue 12, December 2014

3330 ISSN: 2278 – 7798 All Rights Reserved © 2014 IJSETR

The DM9000 supports 8-bit, 16-bit and 32-bit micro

processor interface to internal memory access for

different processors. The DM9000 also supports

IEEE802.3X full- duplex flow control.Enhanced

ARM architecture MMU to support WinCE, EPOC

32 and Linux [19].

Fig2: showing S3C2440.

Instruction cache, data cache, writes buffer and

Physical address TAG RAM to reduce the effect of

main memory bandwidth and latency on performance.

Camera with 20 pins The mini2440 is a practical

low‐ cost ARM9 Single Board Computer (SBC)

with a very high performance/cost ratio. With the

Samsung S3C2440 microprocessor and the use of

professional layout and quality peripheral chips, it is

very robust. The Mini2440 uses a four layer board

design with gold immersion processing, and has

high quality equal length bus routing in timing

critical areas. The production environment and

quality control are the same as those of modern high

speed motherboards [16].

A. Relays:

A relay is an electrically controllable switch

widely used in industrial controls, automobiles and

appliances.

The relay allows the isolation of two separate

sections of a system with two different voltage sources

i.e., a small amount of voltage/current on one side can

handle a large amount of voltage/current on the other

side but there is no chance that these two voltages mix

up [21].

B.LM35:

The LM35 series are precision integrated-circuit

temperature sensors, whose output voltage is linearly

proportional to the Celsius (Centigrade) temperature.

The LM35 thus has an advantage over linear

temperature sensors calibrated in ° Kelvin, as the user

is not required to subtract a large constant voltage

from its output to obtain convenient Centigrade

scaling. The LM35 does not require any external

calibration or trimming to provide typical accuracies

of ±1⁄4°C at room temperature and ±3⁄4°C over a full

−55 to +150°C temperature range. Low cost is

assured by trimming and calibration at the wafer

level. The LM35’s low output impedance, linear

output, and precise inherent calibration make

interfacing to readout or control circuitry especially

easy. It can be used with single power supplies, or

with plus and minus supplies. As it draws only 60 μA

from its supply, it has very low self-heating, less than

0.1°C in still air. The LM35 is rated to operate over a

−55° to +150°C temperature range [21].

3.2. Software:

Software design needs development of cross

compiler, boot loader, embedded web server Linux

platform on the basis of OS.

Linux is open source code OS .the kernel of Linux

is configured to run the proposed embedded hardware

platform. First download the image of the Linux

Kernel is and configure it. Also install the device

drivers for USB to serial interface, provide the

TCP/IP protocol support. For Ethernet select the

DM9000.Establish the file system. This will establish

the Linux platform.

Set up the BOA server. Boa is an open-source,

small-footprint web server that is suitable for

embedded applications. Download version of BOA

from http://www.boa.org/ and cross-compile for

embedded Linux platform will be done to use in our

application. Make a web directory for cgi.bin and

html pages [20].

Common Gateway Interface (CGI) is a standard

method used to generate dynamic content on web

pages and web applications. CGI, when implemented

on a web server provides an interface between the

web server and programs that generate the web

content. These programs are known as CGI scripts or

simply CGIs. Using this script will interface the ARM

processor GPIO pins with web server page [9].

It is based on CGI program and HTTP server .For

front end program is html to communicate with

server. Here HTTP and SSL protocols are used

combined called as HTTPS.CGI based program

reduces the source code. CGI program provides

remote monitoring, control and security [9] .CGI

program is designed on C and Linux platform.

IV. WORKDONE AND RESULTS:

The first software we need on our ubuntu system

in minicom.Minicom is just like hyperterminal.Install

minicom first sudo apt-get install minicom which is

just like hyper terminal [19].

Now connect mini2440 to our system two

connection one from the serial port and next from the

Type B USB plug must be made to the system. On the

Page 3: Building a TCP/IP Web Server System to Acquire and Control Data …ijsetr.org/wp-content/uploads/2014/12/IJSETR-VOL-3-ISSUE... · issue, web pages provide the interface to the embedded

friendly arm board the NAND/NOR switch must be

placed in the NOR position [19].

Now invoke minicom from terminal using

command sudo minicom usually you will get

something like this as shown in fig3on your terminal.

Before that we need a hyper terminal.

We need USB to serial converter. The problem is you

need to configure minicom the port etc use the

command dmesg.This command lists several other

messages also so you have to closely observe to

which port the board is connected. Here serial to USB

converter is used .So the port detected for mine

is ttyUSB0 if you connected it to serial port itself it

will be different.

Fig 3: Process of setting hyper terminal on minicom

Fig4: process of invoking minicom

4.1 Setting up the Supervivi and kernel in

MINICOM

Download usbpush from http://www.friendlyarm.net/dl.php?file=usbpush.zip

Remaining Files Loaded into Mini2440 can be

found in provided CD / images folder.

Push the image files from our system to mini2440

target. When we extract we can see one more usbpush

folder inside that folder there will be a usbpush binary

file give executable permission to that binary file .

sudo chmod +x usbpush/usbpush/usbpush

So you will get the boot loader using command.

sudo minicom

Fig 5: Downloading supervivi and installing

Now the next step is to load supervivi to target

board using usbpush. Supervivi is the boot loader.

Only after this you should push file from the host

system. If the push is successful then it will be back

to the boot loader.

So supervivi is successfully installed. Next is

zImage, Kernel images generated by the kernel build

process are either uncompressed “Image” files or

compressed zImage files. Here we select zImage W35

because MINI2440 with 3.5″ display.

After this step the basic Linux kernel image will be

loaded into memory.

Now we need to Download the root yaffs

image.YAFFS (Flash File System) is now in its

second generation and provides a fast robust file

system for NAND and NOR Flash.

Now select the boot to boot the system.This

willprovide you prompt of friendly arm.

4.2 Configuring ARM GCC:

Then come to your Home Folder there type sudo

gedit .bashrc.

In this file at the bottom paste the path of the

folder by doing “pwd” at the stored file ..for example

...below bold is the path u got from pwd cmd done in

where u saved the folder.

export

PATH=/usr/local/toolschain/4.4.3/bin/:$PATH

export CROSS_COMPILE= arm-none-linux-gnueabi-

After this restart the system, then open a terminal

and type “arm-linux-gcc –v”, then u should received

the output of gcc version .If so u have successfully

installed arm gcc.

4.2 Running a C program on MINI2440: Create a simple Hello World program in C.

This is the program

#include<stdio.h>

int main(){

printf ("Hello World\n");

}

Save it as hello.c .Now compiling it for our target

or mini2440.open terminal and change directory to

the folder where c program is present and issue this

command.

arm-linux-gcc hello.c -o hello

The arm-linux-gcc command was present bcoz we

setup the toolchain early. Now a binary hello will be

present in the folder. Use file command to know the

type of the binary it will suitable for ARM.

Move the binary to mini2440 using pen drive or

sdcard.To see the output execute the binary like this.

./hello

Fig 8: Directory containing files of Firmware

To control the Mini2440 through IP Connection..

the html and CGI files format files are used. CGI -

Common gate interface on.cgi and off.cgi has the

script to assign, change direction and value

index.html has the details of how to operate from a

button. Two communication paths are created one for

transmitting data from server to CGI program which

converts commands to executable files after execution

relay is turned on and also another path from CGI to

server for monitoring.

For Home area we are using router so we need to

set up router configuration with arm s3c2440 using

hyper terminal. HyperTerminal is used for PC

communication with board

Set the boards IP:

IP=192.168.1.230
