INTRODUCTION

IntroductionAutomation is an ancient Greek word that means self-dictated. In modern day terminology, it means quite the same, and in the context of industries, it refers to a complex set up of machines, motors and drives, information, computers and software that are capable of functioning autonomously, without human intervention, under normal circumstances.

What is important to note is that the aim of automation is not to eliminate workers on the shop floor-every automation scientist worth her salt will admit that no machine can ever beat a humans senses and institutions why automate? The primary motive of automation is to tap the predictability and dependability of machine to do something and it will do it in exactly the same way even after the millionth iteration. Therefore the basic goals of automation are to achieve precision and uniformity, eliminate errors and improve the whole process.

In general, the error rate of 1-1.5 percent found in manual working can be brought down to 0.00001 percent with automation. as stakeholders have begun to increasingly demand certain quality standards, automation has also become a key part of todays manufacturing setup. automation is the key in all types of manufacturing, especially in the face of an emerging global economy. From being used to increase productivity and reduce cost, automation has now become vital to increasing product quality. Further, in certain fields like semiconductor chip manufacturing where miniaturization is the key, machines are capable of achieving greater precision and speed than humans-after all,

We cannot expect men with magnifying glasses to sit and assemble the integrated circuit in innumerable chips manufactured every day. Automation is indispensable in such cases.

It is also vital to recognize the influence of the increasingly dynamic nature of supply chains today, on automation. The manufacturing process has to flex in an ad hoc fashion depending on various fashion depending on various factors ranging from fluctuations in the market demand to customized bulk orders from clients. Supply chain management software, enterprise resource management software and so on automatically sync with the control mechanism, to tweak the manufacturing process as required right from the quantity of production to the configuration of parts. Sometimes, the production line itself is changed as required. It is as easy as few button taps today. In a do-or-die market, such flexibility is crucial, and has been one of the key reasons boosting the role of industrial automation.

Automation is also believed to be energy-efficient, as the operation of machine is optimized. Apart from the smooth rhythm, which in itself conserves power, automation also provides the control needed to put machine on or off in a just-in-time fashion, as required, so there is no redundancy.

Automation is also crucial in hazardous areas that humans would not dare to venture-such as oil refineries, manufacturing of certain hazardous chemicals, metal working and welding, and nuclear reactors. Automation machines, controlled through wireless networks, are more effective in such area than a scared human worker.

More so, in the US and other developed countries, some companies, though not motivated by any of the preceding reasons, have also been forced to go in for automation-for want of semi-skilled labours

As the technology advances there is an increasing need for improvement in the existing technology. So as we found out there are some areas where we can provide a single unit control which will be most beneficial for providing an efficient working in the industry. As the industry performing the manual work function so we are trying to provide a single unit control to drive the multiple application under the regulated control format so a single person can handle many *applications at a time with more easy and comfortably *.

With the advent of modern technology, the human brain is working day by day to develop complex and more technology specific products which have multifarious applications in the different aspects of work field.

This project deals with designing of one such product which can be used multifariously in various commercial and official activities. An introduction to this project can be given as designing of a controlled system through a PC.

The PC controlled system gives us the facility to control big organizations electrical system under a single administrator which saves the valuable electrical power and provides us to have the control of any electrical devices.

It consists of a panel which is attached to various electrical devices from which a single person can handle all systems from one position. These operations are controlled by interfacing it using buses with a personal computer. All operations are controlled through keyboard inputs of a PC. All these executions are made possible with the help of a most powerful programming language the Visual Basic language. The software is comprised of language programs when executed give the desired physical results hence all operations can be easily managed with the PC.

*Benefits Of SCADA:* Efficient Control & Monitoring of System Secure uses encryption algorithms to store data.

Tamper proof.

Security features visual and electronic.

Useable under harsh environment.

Conforms to ISO/IEC standards.

Eliminates the need for carrying paper documents and traditional reporting wherein use of staff resources expenses related to travel, logistic effort and reduced man based dependency for committed errors and repetitive mistakes that can be due to reasons like fatigue and working conditions of harsh weather severities. The important control and monitoring aspects that needs to be atomized by using SCADA and the availably proved technologies that should benefit the in saving their resource utilization, attain transparency in fast data collection and save revenues while attaining maximum benefit with optimum resources.

*VISUAL BASIC *

VISUAL BASIC is the super set of BASIC LANGUAGE. BASIC is windows, it provides graphical user interface (GUI). Since it is GUI application build in VB are more attractive. VB was launched in 1997 in which local database and remote data base connectivity is possible. VISUAL BASIC is the fastest and easiest way to create applications for Microsoft windows programming VISUAL BASIC provides with a complete set of tools to simplify rapid application development.

VISUAL part return to the method to create the graphical user interface (GUI). Instead of writing various lines of code for creating the appearance and location, we can directly place the object and the screen and set its different properties such as shape, colour etc. BASIC part refers to the BASIC (Beginners All Purpose Symbolic Instruction Code) language VISUAL BASIC has evolved from the original BASIC language and now contains several hundred statements, functions and keyboards, may of which relate directly to the windows GUI. Any beginner can create the application by just learning a few of the keywords.

One of the most significant change in visual basic. 6.0 are the Integrated Development Environment (IDE).IDE is a term commonly used in the programming world to describe the interface and environment that we use to create our application. It is called integrated because we can access virtually all of the development tools that we from one screen called an interface. The IDE is also commonly referred to as the design environment, or the program.

Visual basic programs are builds around events. Events are various things that can happen in a program. This will becomes clearer when studies in contrast to procedural programming. In procedural languages, a application written is executed by checking for the program logically through the program statement, one after another. For a temporary phase, the control may be transferred to some other point in program. While n an event driven application, the program statement is executed only when a particular event calls a specific part of the code that is assigned to the event. The code entered in the change event fires when there is a change in the contents of the text box

The click event fires when the text box control is clicked.

The mouse move event fires when the mouse is move over the text box.

*DATABASE*

To launch Access, click the Microsoft Access button on the Microsoft Office Shortcut Bar, or click the Start button and choose Programs Microsoft Access from the menu. When Access starts, youll see a dialog box like the one. The names you see listed in the bottom half of the dialog box will vary depending on the database projects youve already started. At this point, you can.

Create a database from scratch or with the Database Wizard

Create a data access page for viewing Access data with Internet Explore

Create an Access project Open a database or project youve already created

*Elements of an Access Database*

The heart of a database is the information it holds. But there are other important elements, usually referred to as objects, in an Access database. Here are the kinds of objects youll be working with:

Tables hold information.

Queries let you ask questions about your data or make changes to data.

Forms are for viewing and editing information.

Pages are HTML (Hyper Text Markup Language)

Reports are for summarizing and printing data.

Macros perform one or more database actions automatically.

Modules are another type of Access object that you may or may not work with. A module is a program you write using VB (Visual Basic, the programming language included with Office) to automate and customized database functions. Youll see how to create a customized database, but it will all be done without programming. CONCLUSION AND SCOPE OF FUTURE WORK

In the designing of our projects, we have kept in mind the

user . in the implementation part which interacting with the user we had given lot of guideline to user with various massages. Visual basics very good programming languages for implementation of any data base projects because it has powerful control with which you can easily implement various facilities in our projects .the screen are very user friendly.

Scope for future work :-

This projects can be made online and extend the to Human Machine Interface (HMI) which are from out of station they can Access online data and the process will be very fast.
