Computer-oriented control system

Means that the system is controlled by computer(PC) or controller
Usually , it is for process control purposes


3 elements involved :




Types of computer-oriented control system

1. DCS (Distributed control system)
2. PLC (Programmable Logic Controller)
3. PC (Personal Computer)
4. Embedded controller

Computer




Dedicated-application system

• Where the system is dedicated to perform a single task or a single group of tasks
• Examples : Microwave, ECU, Calculator
• A microcomputer/controller receives input information
• Executes a sequence of instruction to process the information
• Provides output

Example of Dedicated-application system

Engine status display system

1. The input information (engine parameter: temperature, oil pressure,etc) is converted to an electrical quantity by some type of transducer.
2. The electrical quantities are then converted to a digital form to be inputted to the microcomputer system (µC)
3. The µC processes the input data
4. Then outputs the information to the display panel

sensor

• Electronic transducer that converts a physical quantity into an electronic signal.
• Detect temperature, light, force, strain, etc

Type of sensor

• Color sensor
• Proximity sensor
• Motion sensor
• pH sensor
• Load cell
• Photo cell
• Humidity sensor

BASIC SENSOR CIRCUITS

The bridge circuit

Is used to compare the signal to some setpoint value

The Op Amp Circuit

Is used to amplify any sensor signal that is too small
