Specific educational targets
The aim of the course is to provide skilles and competences about typical informatics methodologies and technologies involved in industrial processes amnagement. At the end of the course, the student should be able to deal with the computer interfacing with different control systems, to acquire data coming from sesors, to dirve usual industrial actuators and to implement simple digital filtering on the acquired signals.
Moreover, throughout the course and in a specific section, the student will be introduced to embedded systems with an overview of typical computer architectures employed in this field.
Course program
Data acquisition
Digitale interfacing and signal detection with levels and edges: digital COTS components driving (latch, buffer,
counters). Electrical and algorithmic filtering. Algorithms and their C implementation for pulse signals acquisition, for
incremental optical encoders interfacing, for angular velocity detection.
Pulse emission and numerical codes from absolute encoders acquisition.
Analogic interfacing
Data acquisition chain, commercial component and examples. Techniques for transducing, multiplexing, ADC conversion. Sigma/Delta converters.Hints on linearisation, calibration and numeric ARMA filtering: mobile average and exponential digital filters.
