Objectives The course deals with the process control theory and the automation in industrial applications.
The subject Measures for Automation and Industrial Production aims to provide students with the necessary knowledge for the proper management of modern industrial production processes measurement and control systems. The course will develop the basic concepts and methodologies for proper management of the measures in process automation. The ultimate goal is to guide students in the methodological design of experiments and the development of virtual instrumentation for the monitoring of plants and production testing. It will also provide the basis for the development of tests for the characterization and control of reliability, quality and improvement of an industrial production process. The course has a strong experimental connotation, tied to an intensive use of the laboratory in order to understand the basic concepts relating to the acquisition and data processing by means of distributed systems and to remote control of measurement instrumentation using network protocols.
Programme Data acquisition systems. Field devices: sensors, actuators, and controllers. Metrological characteristics of the sensors. Conditioning circuits. Data processing techniques for extracting information of measurement: digital filtering, deconvolution. Techniques of immunity to interference and noise. Shields and filters to reduce interference on the measurement. Automatic measurement systems. Distributed architectures. Standard communication between instrumentation: RS232, IEEE 488, Ethernet, PXI, VME / VXI. Issues with Real-Time applications. Programming environment dedicated to the instrumentation: LabVIEW. Virtual instrumentation for monitoring and testing of the production. Equipment calibration and e-calibration. Techniques for improving industrial production. Methods for control of the reliability and credibility of the results. Design of experiments and parametric optimization. Control cards. Advanced techniques of phase locking of signals and synchronization acquisition of signals coming from different acquisition systems. Development of applications for remote control of digital instrumentation via Matlab and LabVIEW. Realization of virtual instruments for real-time control of critical industrial processes, remote measures (Internet).
The laboratory activity will cover practical exercises relating the use of automated instrumentation for measurement, data acquisition boards, the use of the standard communication interfaces previously listed and the development of procedures for the management of board instrumentation for PCs. The main objective of the exercises consist in the realization of virtual instruments for real-time controlling of critical industrial processes, remote measurements (Internet), development of applications for remote control of digital instrumentation via Java, C/C + +, Matlab, LabVIEW .
Practical laboratory exercises:
1) Implementation of a thermoresistance-based temperature meter. Realization of the conditioning circuit, calibration and verification of performance and metrological characteristics.
2) Implementation of a temperature meter based on microcontoller through the use of thermocouples and electronic sensors chips. Construction of signal conditioning circuits, calibration and performance verification. Comparison with the performance of the thermoresistance-based one.
3) Measuring system for time-varying quantities: automatic acquisition of the transient discharge of an RC circuit. Implementation of a measurement management program, performance testing using external instrumentation and RS232/IEEE488 interface. Analysis of problems related to the time discretization.
4) Repetition of previous experience using a data acquisition board internal to the computer. Writing of a management program for the acquisition board in a Windows environment and use of integrated packages. Comparison of performances obtained with the two methods.
5) Improvement of the accuracy of transient temperature measurement through digital signal processing.
6) Automatic station for controlling the temperature of an enclosed environment. Temperature control and decision risks: decision-making, ISO 14253 and control charts.
7) Automatic station for measuring the phase difference between two signals by the use of an oscilloscope: RC circuit.
8) Automatic station for measuring the active and reactive power of an RC circuit by the use of an oscilloscope. Comparison of the measure with a numeric counter.
9) Automatic station for the characterization of an electric motor.
10) Realization of a variable resistance through an actuators board and a swithc matrix.
11) Automatic station for the metrological characterization of an A/D converter.
