Computer Control

Computer Control

1. Advantages

   • Can work for 24hours a day without a break
   • Can work without holidays or sick breaks
   • Works for free, No wages
   • Can repeat actions accuretly over and over again
   • Can process data from sensors very quickly

2. Disadvantages

   • The Software for the control system is specialist and can cost alot of money to be developed
   • If the computer beaks or stops working the software won't work.
   • The software can't react to unexpected events that could happen
     • It can only do what it has been programed to do
   • It won't work if there is a power cut
   • People might want to have a human expert to do it instead although computer control softwares can do the job just as well

       • Pilot

3. What is it?

   • Computer control means that the computer is part of a control system. The computer is normal used to run the control program. "Computer" is used very loosely as it can be a microchip or processor embedded with the equiptment.

4. Sensors (input)

   • ADC analouge to digital converter (Process)
     • The computer on takes in the values "0" or "1", the ADC converts the information from Analouge to digital which is waves to numbers.
     • Output
       • Once the process has be done the action will take place depending on what it was programed to do
         • e.g
           • If it's too cold the windows will close or if it's too hot they heating will be turned off etc.
   • A sensor is a device that messures an action for example a matt that detects someone stepping on it or a heat sensor that checks for certin tempecture
