acquisition, Industrial automations and safety measures etc,. Users can monitor & control remote machines/systems by using an
embedded web server. The main objective of this system is used to monitor the industrial parameters and control the various
machines/systems in the industry from anywhere in the world through embedded web server. The machine/instrument is

1 INTRODUCTION
DATA-ACQUISITION systems are in huge demand in
industry and consumer applications. In this application, it is
necessary to monitor the industrial parameters with great
accuracy [1]. Monitoring and controlling is significant in
industrial automation. With the development of modern
industry, the monitoring of industrial parameters gets higher
[2]. But also controlling of the machine/instrument is required.
The monitoring and controlling becomes a distributed
framework. In framework only wired communication is used
between the host and front panel. These systems cannot be
widely used and maintenance cost becomes high. In order to
solve the problem, we use a GPRS technology to monitor the
industrial parameters [3].
Online Interactive Data Acquisition and Control system
play the major role in the field of measurement and control
systems. It is designed with many electrical and electronic
components and makes the system more complicated [4]. So we
utilize a system that contains a Data acquisition and control
system. In this system we can monitor and control the industrial
devices.
The data acquisition & control devices are best solution for
unmanned devices. A single person can monitor and interact
with the ongoing work from a single base station through web
server. An acquisition unit design to collect data in their
simplest form which is based on Linux [5]. The Linux operating
system is simple, but difficult to recognize so to overcome this
limitation we employ ARM 7 processor which have a Real
Time Operating system & we design data acquisition unit with
embedded language. For a wide range of data transmission the
client and server architecture is not suitable. So, the central
server is replaced by a web server [6].
The proposed system is low cost and portability. It contains
the GPRS technology and it helps to communicate with GSM.
The GSM has an inbuilt TCP/IP protocols for internet data
transfer. An embedded web server is an easy way of monitoring
and controlling the industrial machines. The client can monitor
and control the machines/instruments from anywhere in the
world. The sensor’s are used to monitor the parameters of the
machine/instruments. The cryptography method is used in this
system for data security.
The structure of the paper is as follows. Section II
explains the concept of an embedded web server. Section III
will describe the operation when different sensor’s connected to
the embedded system and the software algorithm of the system.
Section IV explains the experimental results. Finally, section V
presents the conclusion and future work.
2 EMBEDDED WEB SERVER
Every client can access the industry directly without any
interaction with additional server and modules [7]. Fig 1 shows
proposed DAC system with an embedded web server. This
contains a portable ARM 7 processor. An ARM processor is
responsible for handling all tasks like measuring & conversion
of signals, data base updating, communicating with owner by
sending HTML pages. An ARM 7 processor manages all tasks
in parallel in tiny amounts of time. The client can monitor and
control the various industrial parameters in the web server.](https://image.slidesharecdn.com/ictte097-150928064334-lva1-app6892/85/Arm-Based-Real-Time-Monitoring-and-Controlling-of-Industrial-Parameters-Using-GPRS-1-320.jpg)

Client can interact with the industry by giving instruction
on web page. The system has numerous advantages: user-
friendly, low-development cost and high maintainability.
3 SYSTEM DESIGN
3.1 Existing System
Networked embedded systems have become quite
essential for monitoring and control the industrial devices. The
existing system is used to monitor only the parameters of the
machine/instruments in the industry through web server [1]. It
do not contain any security. The main advantage of the
proposed system design is the client can monitor and control the
machines/instruments through an embedded web server.
Encryption and decryption is carried out in the data sharing in
the internet. This system reduces the manpower in the industry.

Fig 2 General structure of the system
Different types of sensor’s such as temperature sensor,
pressure sensor and speed sensor is connected to each I/O
channel of the ARM processor. The data from sensors is
collected & maintained by the ARM processor. GSM modem is
connected to the transmitter and receiver pin of ARM
processor. GSM modem shares data from the board to internet.
In Web page, the data can be monitored by the client from
anywhere across the world through internet. The client can
control the machine/instrument by giving ON/OFF in the web
page. The relays are used to control the machine/instrument.
The cryptography is applied in this system for security.
3.3 Software
Keil µVision IDE is a simple integrated development
environment (IDE) that runs on regular personal computers and
provides tools for a powerful, easy to apply and easy to learn
environment for developing embedded applications. It includes
the components we need to create, debug and assembles our
C/C++ source files, and incorporate simulation for
microcontrollers and related peripherals. It also has RTX RTOS
Kernel Library, Device Database, Debugger and Analysis tools
and complete device simulation. It also has RTOS and
Middleware components for implementing time-critical
software and shorten the development cycle. Further, it has
Flash File system, USB Device Interface and CAN Interface.
The Keil ULINK-JTAG adapters connect the USB port of a PC
to the target hardware. This enables us to download, test and
debug the final executable hex code generated by the Keil IDE
to the target hardware. The embedded c code is designed to
monitor the parameters and to control the machine/instrument.
The encryption and decryption code is also designed in this
system.
The software consists of RTOS and HTML. The
application runs in the form of tasks. The RTOS is applied to
manage the tasks. The tasks are real time operations. The
software that runs on the embedded web server follows TCP/IP
protocols.
The HTML or Hyper Text Mark-up Language is
used to design the embedded web page. The HTML page is
used for data communication between the client and server. The
HTML page displays the parameter information of the
machine/instrument. The HTML page is saved on the board.
ALGORITHM
Step1: Initialize VPDIV register for setting clock frequency.
Step2: Initialize ADC ports P 0.6,P 0.7,P 0.8 for pressure

parameters.
Step3: Initialize the ports P 0.15 and P 0.17 for the relays to
control the machine.
Step4: Interface GSM to the transmitter and receiver pin of
ARM processor.
Step5: Initialize and enable the interrupts.
