safeguard passengers‚ crew and aircraft is now met by ground based infrastructure‚ in which air traffic controllers issue mandatory instructions to pilots. The aim of Air Traffic Control Service is to ensure a safe‚ orderly and expeditious flow of air traffic. 3. Primary objective of Air Traffic Control is to prevent collisions between aircraft. In order to achieve this objective‚ the Air Traffic Controller issues clearances to provide safe separation between aircraft at any given time. Internationally

Timeframe More Sophisticated Safety Controllers We will see the wider adoption and greater sophistication of safety controllers‚ which includes such devices as safety relay modules‚ relay-controller hybrids‚ safety PLCs‚ and specific function safety controllers‚ such as a muting controller. The next step up in the quest for more intelligent safety controls are the relay-controller hybrids‚ often described as modular controllers. These are simple controllers with relay or electronic-based expansion

What is SCADA? Axel Daneels‚ Wayne Salter ‚ IT/CO Abstract An industrial SCADA system will be used for the development of the controls of the four LHC experiments. This paper describes the SCADA systems in terms of their architecture‚ their interface to the process hardware‚ the functionality and the application development facilities they provide. Some attention is also paid to the industrial standards to which they abide‚ their planned evolution as well as the potential benefits of their

2. PROGRAMMABLE LOGIC CONTROLLERS 2.1 INTRODUCTION Control engineering has evolved over time. In the past humans were the main method for controlling a system. More recently electricity has been used for control and early electrical control was based on relays. These relays allow power to be switched on and off without a mechanical switch. It is common to use relays to make simple logical control decisions. The development of low cost computer has brought the most recent revolution‚ the Programmable

A REPORT ON AUTOMATION OF CONVERTOR TILTING DRIVE USING PLC AND VVVF DRIVES Abstract: Industry is a home of various kinds of machines that are used for numerous processes and treatments. The control and working of these machines have been automated through the use of PLCs. Automation has resulted in faster production rate‚ increased accuracy‚ better quality and reduced faults and human errors. PLCs and VVVF drives are used in most of the sections and units at VISL because of their simple methods

Thirty-six years ago‚ on August 3‚ 1981‚ more than 12‚000 members of the Professional Air Traffic Controllers Organization (PATCO) walked out‚ releasing multiple events that has since redefined labor unions. In rejoinder to the walkout‚ President Ronald Reagan delivered one of the crucial statements of his term. He said the striking air-traffic controllers were in desecration of the law; if they did not report to work within 48 hours‚ they would be fired. Long after Reagan’s presidency‚ tensions

CHAPTER II: THEORETICAL FRAMEWORK 2.1 Introduction In this fast-paced era‚ the need for faster‚ reliable and more convenient systems increases in any aspects of the society. Certain problems exist such as the slow manual sales system of some evolving business firms‚ effective reduction of the number of vehicular accidents that occur‚ security problems in some establishments or even in parking areas and more. One of the reasons why these problems arise is the lack of innovations that is why automated
