Automated Systems

• An automated system is a combination of hardware and software designed to work automatically without any human intervention
• Use sensors, microprocessors and actuators to control processes
• Industrial uses include within nuclear power stations, and paracetamol manufacture
• Nuclear power stations have a distributed control system (DCS), and a supervisor can override any process if needed
• Transport uses include in Adaptive Cruise control and self parking cars. These systems control the brakes, accelerators and the steering of a car. They use infrared laser sensors and cameras
• Weather stations measure the weather, and rainfall using a bucket and level sensors. Operate 24/7 in all conditions and constantly collects data to send out weather reports
• In Gaming simulations, accelerometers respond to the tilting of input devices. They send sound signals to create realism and alter images on screen
• Lighting systems use light/infrared sensors to turn lights on or off according to lighting levels. They reduce energy consumption
• Advantages:

  • Faster and more consistent than humans
  • Safer in hazardous environments
  • Less expensive long term and more efficient at using materials
  • System more likely to run optimally
• Disadvantages:

  • Often expensive to set up initially
  • Always a possibility for a situation that hasn’t been programmed for to occur
  • Risk of cyberattacks
  • Expensive maintenance
