Automated Systems

Advanced technologies are revolutionizing various industries through the integration of automated systems, sensors, and robotics. Sensors, which measure analogue signals, are essential in detecting changes in temperature, light, and pressure, and these signals are converted to digital form for processing by computers.

Systems analysis

The systems analyst does the systems analysis of a factory/workplace.


  • He/she reviews the tasks compelted in the present system
  • Decides whether introducing computers or a new system would make it more efficient
  • Designs the new system
  • Implements the new system.
  • Advantages - SHAARE

    Sensors

  • These sensors measure ANALOGUE signals. Signals which vary constantly.
  • The signals they collect are sent back to the computer controlling the device
  • The controller decides on a course of action
  • Interface
    D to A converter

    Digital to Analogue converter

    Used to convert signals from the processor to the analogue device. Examples of these devices are motors and switches.

    A to D converter

    Analogue to Digital Converter

    Used to convert analolgue signals from the sensor to digital signals for the computer to process

    magnetic
    light
    Temperature
    Moisture
    Pressure

    CAD/CAM

    Computer Aided Design

    The design of components, cars, buildings etc using computers:



  • more accurate
  • quicker to create design
  • can be changed easily

  • Graphics tablets can be used to create the drawing

    Intelligent software
    Embedded systems

    A computer system that is dedicated to one task.

    Usually a microprocessor embedded into the object.

    Examples are mobile phones, ipods, microwaves etc.

    Control software held in ROM

    Control software is used to give instructions to automated machiners (eg. robots).

    It is known as ROM software and is burnt onto ROM chips so that it cannot be altered.

    Altering the software might cause the machinery to malfunction causing loss of thousands of pounds or even causing an accident.
