Chapter 1 INTRODUCTION TO AUTOMATION 1.1 WHAT IS AUTOMATION? It is the technique of making an apparatus, a process, or a system operate automatically. Automation federation defines automation as “The creation and application of technology to monitor and control the production and delivery of products and services.” Automation means use of Available technologies to reduce the need of Human work. Mechanization provides human operators machinery to assist themselves with the muscular requirements of work…… While Automation greatly decreases the need for human sensory and mental requirements as wellAutomation is a technology concerned with application of mechanical, electronic and computer-based system to operate and control system. 1.2 OBJECTIVE …show more content…
• Improved robustness (consistency), of processes or product. • Increased consistency of output. • Reduced direct human labor costs and expenses. 3.3 DISADVANTAGES OF AUTOMATION: Following are the disadvantages of automation: • Causing unemployment and poverty by replacing human labor. • Security Threats/Vulnerability: An automated system may have a limited level of intelligence, and is therefore more susceptible to committing errors outside of its immediate scope of knowledge (e.g., it is typically unable to apply the rules of simple logic to general propositions). • Unpredictable/excessive development costs: The research and development cost of automating a process may exceed the cost saved by the automation itself. • High initial cost: The automation of a new product or plant typically requires a very large initial investment in comparison with the unit cost of the product, although the cost of automation may be spread among many products and over time. 3.4 APPLICATIONS OF AUTOMATION: Following are the applications of automation: 1. Automation in Industries. 2. Automation in power plants. 3. Automated mining. 4. Automated highway systems. 5. Automated waste …show more content…
The size of the inductive coil and the capacitor are matched to produce a self-sustaining sine wave oscillation at a fixed frequency. The coil and the capacitor act like two electrical springs with a weight hung between them, constantly pushing electrons back and forth between each other. Electrical energy is fed into the circuit to initiate and sustain the oscillation. Without sustaining energy, the oscillation would collapse due to the small power losses from the electrical resistance of the thin copper wire in the coil and other parasitic
