ETHERNET BASED INDUSTRIAL APLICATION

CONTROL SYSTEM

INTRODUCTION

Computer communication systems and especially the Internet are playing an important role in

the daily life. Using this knowledge many applications are imaginable. Home automation, utility

meters, appliances, security systems, card readers, and building controls, which can be easily,

controlled using either special front-end software or a standard internet browser client fromanywhere around the world.

A server is a system which hosts a web site and provides services for any requesting clients. The

general purpose servers compose of an operating system, the web pages or the application and

a huge amount of memory and sometimes a special hardware.

In This Project we are using TCP/IP protocol implementation for controlling of the apparatus

from remote location using internet connection System is good example of interoperable

system and highly compatible. This project is designed to make industrial monitoring and dataacquisition In This project different sensors are used to measure the parameters like RPM

methane gas & temperature. That will be sent to the local PC first and then to the server pc

using TCP/IP protocol

System Architecture

A server is a system which hosts a web site an provides services for any requesting clients. The

general purpose servers compose of an operating system, the web pages or the application and

a huge amount of memory and sometimes a special hardware Fig shows a typical client-server

architecture where, the client accesses the server through the LAN router and the Internet.

Whenever, the client wants to access the sever, it sends the request to the server, this request

is taken by the router, which is connected to the Internet. The web processes the request made

and finally connects to the desired server, access the requested data and sends the data to the

client

Transmission Control Protocol

The Transmission Control Protocol (TCP) is one of the core protocols of the Internet Protocol

Suite. TCP is one of the two original components of the suite, complementing the Internet

Protocol (IP), and therefore the entire suite is commonly referred to as TCP/IP. TCP provides

reliable, ordered delivery of a stream of bytes from a program on one computer to another

program on another computer. TCP is the protocol that major Internet applications such as the

World Wide Web, email, remote administration and file transfer rely on. Other applications,

which do not require reliable data stream service, may use the User Datagram Protocol (UDP),

which provides a datagram service that emphasizes reduced latency over reliability.

Brief Description

TCP provides a communication service at an intermediate level between an application program

and the Internet Protocol (IP). That is, when an application program desires to send a large chunk

of data across the Internet using IP, instead of breaking the data into IP-sized pieces and issuing a

series of IP requests, the software can issue a single request to TCP and let TCP handle the IP

details. IP works by exchanging pieces of information called packets. A packet is a sequence of

octets and consists of a header followed by a body. The header describes the packet's destination

and, optionally, the routers to use for forwarding until it arrives at its destination. The body

contains the data IP is transmitting.

Due to network congestion, traffic load balancing, or other unpredictable network behavior, IP

packets can be lost, duplicated, or delivered out of order. TCP detects these problems, requests

retransmission of lost data, rearranges out-of-order data, and even helps minimize network

congestion to reduce the occurrence of the other problems. Once the TCP receiver has

reassembled the sequence of octets originally transmitted, it passes them to the application

program. Thus, TCP abstracts the application's communication from the underlying networking

details.
