Unit 6.1 - Automated Systems Flashcards
SCAR
-Sensors –> ADC –> Microprocessors
-Comparison between stored values
-Action from result of comparison
-Repeats
Automated systems definition
combination of software and hardware (sensors, microprocessors, actuators) designed and programmed to work automatically without the need for any human intervention
sensor definition
input devices that take readings from their surroundings and send this data to a microprocessor / computer
microprocessor definition
processes the data and takes the necessary action based on programming
advantages of automated systems [7]
-faster than humans
-safer in dangerous environments
-less expensive long run (less workers needed)
-can run under optimum conditions
-increase productivity overall
-consistent results
-more accurate and faster results
disadvantages of automated systems [5]
-expensive to set up / purchase initially
-possibility that a set of conditions that was not prepared for during development occurs
-constant fear of cyber attacks (hacking)
-enhanced maintenance needed (expensive)
-could lead to unemployment
advantages in industry [6]
-faster than humans
-safer
-process runs under optimum conditions
-less expensive long run (no need for workers monitoring process 24 hours a day)
-higher productivity / more efficient material use
-more consistent results
disadvantages in industry [4]
-expensive to set up in the first place
-set of conditions that were not considered during testing could occur
-enhanced maintenance (supervisors) always needed
-subject to cyberattacks
advantages in transport [6]
-few parking spaces used
-avoids traffic disruption
-cars fit into smaller spaces
-fewer dents and scratches to cars
-safer (monitor all objects)
-consistent results
disadvantages in transport [5]
-loss of skills (over-relying on automated systems)
-faulty/dirty sensors / cameras can lead to malfunction
-sensors may not pick up low kerbs
-expensive
-requires additional maintenance to make sure it functions correctly
advantages in agriculture [6]
-reduced labour costs (only supervisor needed)
-better and more efficient control of process (irrigation)
-better control of resources (water)
-faster response than human
-safer (hot weather)
-different crops = different watering requirements
disadvantages in agriculture [3]
-expensive to set up initially
-high maintenance costs
-increased need to maintain water channels (check of system works correctly at all times)
advantages in gaming [2]
-add realism to games
-more immersive games experience
advantages in lighting [5]
-control light sources automatically
-reduces energy consumption (lights only on when necessary)
-wireless connections chosen (safer)
-longer bulb life (turning off when not needed)
-can program new light displays for different occasions
disadvantages in lighting [3]
-expensive to set up initially
-wireless connections may be less reliable than wired systems
-expensive maintenance is required for consistent performance
