Monitoring, control & feedback: ICU, traffic lights & modern cars
Narrated lesson · press play
Computers quietly watch over things for us, and sometimes they take action to keep those things just right. In this lesson you will learn the difference between monitoring and control, meet the feedback loop that lets a system correct itself, and see it working in a hospital intensive care unit, at traffic lights, and inside a modern car.
What you'll learn in this lesson
By the end you should be able to (NSSCO Computer Studies 2.1.4):
- Describe monitoring and control systems
- Describe how the feedback process takes place in a control system
- Describe the use of computer systems to monitor hospital patients in an intensive care unit such as: how vital signs are monitored, what triggers the system to activate an alarm
- Describe the use of computer systems to regulate traffic control by the use of traffic lights, such as: how models/simulators are used to set traffic light timing, types of sensors used to gather data, how systems manage timing of lights
- Discuss the role of computers in modern motor vehicles, such as: airbag systems, stability control for brake systems, controlling the heat of the car engine, cruise control, active parking assistance, rain and light sensors
