AUTOMATION DEFINITION PDF

Noun. the technique, method, or system of operating or controlling a process by highly automatic means, as by electronic devices, reducing human intervention to a minimum. a mechanical device, operated electronically, that functions automatically, without continuous input from an operator. act or process of automating. The definition of automation is the use of machines and technology to make processes run on their own without manpower. An example or automation is the. Definition of automation - the use or introduction of automatic equipment in a manufacturing or other process or facility.

Automation Definition - What does Automation mean? Automation definition is the creation of technology and its application in order to control and monitor the production and delivery of various goods and services.

AUTOMATION DEFINITION PDF

It performs automation definition that were previously performed by humans. Automation is being used in a number of areas such as manufacturing, transport, utilities, defense, facilities, operations and lately, information technology.

Automation

Free Webinar Register Today! The "lock in" contacts in the start circuit and the main power contacts for the automation definition are held engaged by automation definition respective electromagnets until a "stop" or "off" button is pressed, which de-energizes the lock in relay.

AUTOMATION DEFINITION PDF

Suppose that the motor in the example is powering machinery that has a critical need for lubrication. In this case automation definition interlock could be added to insure that the oil pump is running before the motor starts.

Timers, limit switches and electric eyes are other common elements in automation definition circuits. Solenoid valves are widely used on compressed air or hydraulic fluid for powering actuators on mechanical components. While motors are used to supply continuous rotary motion, actuators are typically a better choice for intermittently automation definition a limited range of movement for a mechanical component, such as moving various mechanical arms, opening or closing valves, raising heavy press rolls, applying pressure to presses.

Computer control[ edit ] Computers can perform both sequential control and feedback control, and typically a single computer will do both in an industrial application.

Automation

Programmable logic controllers PLCs are a type of special purpose microprocessor that replaced many hardware components such as timers and drum sequencers used in relay logic type systems.

General purpose process control computers have increasingly replaced stand alone controllers, with a single computer able to perform the operations of hundreds of controllers. Process control computers can process data from a network of PLCs, instruments and controllers in order to implement typical such as PID control of many individual variables or, in some cases, to implement complex control algorithms using multiple inputs and mathematical manipulations.

They can also analyze data and create real time graphical displays for operators and run reports for operators, engineers and management. Control of an automation definition teller machine ATM is an example of an interactive process in which a computer will perform a logic derived response to a user selection based on information automation definition from a networked database.

The ATM process has similarities with other online transaction processes. The different logical responses are called scenarios. Such processes are typically designed with the aid of use cases and flowchartswhich guide the writing of the software code.

The earliest feedback control mechanism was the water clock invented by Greek engineer Ctesibius — BC Early history[ edit ] Ctesibius's clepsydra 3rd century BC.

It was a preoccupation of the Greeks and Arabs in the period between about BC and about AD to keep accurate track of time. In Ptolemaic Egyptabout BC, Ctesibius described a float regulator for a water clocka device not unlike the ball and cock in a modern flush toilet.

This was the earliest feedback controlled mechanism. Another control mechanism was used to tent the sails of windmills. It was patented by Edmund Lee in The design of feedback control systems up through the Industrial Revolution was by trial-and-error, together with a great deal of engineering intuition.

Thus, it was more of an art than a science. In the midth century mathematics was first used to analyze the stability of feedback control systems. Since mathematics is the formal language of automatic control theory, we could call the period before this time the prehistory of control theory.

What is Automation? - Definition from Techopedia

In Richard Arkwright invented the first fully automated spinning mill driven by water power, known at the time as the automation definition frame. The centrifugal governorwhich was invented by Christian Huygens in the seventeenth century, was used to adjust the gap between millstones.

Bunce of England in as part of a model steam crane. The governor was able to handle smaller variations such as those caused by fluctuating heat load automation definition the boiler. Also, there was a tendency for oscillation whenever there was a speed change.
