Process Control

Process Control

1. Process Control in Industry

   • Process Control is a Real Time system
   • It allows the system to respond immediately to data received from sensors
     • This repetition is called a Feedback System

2. Robotics

   • Robots a machine that can be programmed to perform many actions
     • Robots can carry out:
       • Boring Jobs
       • Dangerous Jobs
       • High Precision Jobs
       • Heavy Jobs
     • Instructions can be written using special computer programming language
     • Some can be guide manually and remember what they have to do

3. Bionics

   • Bionics is the linking of machines to living things
     • Such as an Artificial Limb controlled by the brian

4. Computer control in Hospitals

   • Computers are used to control life support machines because they are more reliable than humans
   • Inputs include: Pulse Rate, Temperature, Blood Pressure, Blood gasses and Breathing rate monitors
   • Readings are taken a specific intervals and often frequent intervals such as fractions of a second
   • Alarms and other displays are used to notify that something is wrong with the patient

5. Artificial Intellligence

   • AI gives machines the appearance of being intelligent
     • E.g. Predictive text
   • Systems that can read handwriting
   • Systems that analyse walking styles and identify possible suspicous activity

6. Expert Systems

   • An Expert System takes the place of a human expert
   • A database of knowledge can be used and deductions made on the basis of the results
