Study Notes
History of Automation
-
Ancient Examples:
- The Great Pyramids used basic forms of automation.
- The Roman Empire used rudimentary flow meters in aqueducts.
- In the 3rd century BC, the first true control device, a water clock valve, was invented.
-
Early Automation:
- James Watt invented the flyball governor in 1772, still used to control steam engines.
- The flyball governor is a simple mechanical device that controls the speed of a steam engine through centrifugal force and feedback loops.
-
Modern Automation's Beginnings:
- Automation started taking off in the 1960s, driven by automotive manufacturing assembly lines.
- Early automation relied on hardwired electrical and electromagnetic relays, allowing basic logical functions like AND, OR, and counting.
-
Programmable Logic Controllers (PLCs):
- Modern PLCs evolved from the hardwired relay systems of the 1960s.
- PLCs are small, versatile devices with CPUs, input/output cables, and sometimes ethernet and wireless connections.
- PLC advancement stems from the early hardwired relay systems.
