Computer-Based Instrumentation: A Boost for Industrialization

2008

This paper discusses the various methods by which instruments used in industries and process control can be computer-based. Instruments can be connected to computers so that collecting, controlling, and adjusting parameters under the supervision of computer program is facilitated. This paper discusses various methods of data acquisition by which properties exhibited by various instruments can be acquired in an appropriate form, processed, and made ready for the computer environment. This paper also examines the means of transmitting acquired signals to the appropriate interface system, which eventually links the computer system for processing and control. It thereafter concludes by advising the instrument and process control engineers to understand the main principles of communication to ensure proper integration into process control system and industrial environment.

PC-Controlled Electronics Laboratory Multi-Apparatus

2007

This paper contains the design of an integrated voltme er, ammeter, ohmmete , logic probe, oscilloscope, DC voltage supply and a signal generator. All of these instruments a e controlled using a personal computer through the PCI bus. The hardware needs to be supported by the equally important software for this system. The system in this case includes the GU for the user to control the instruments as well as get feedback through the monitor. The same software is also responsible for doing the necessary adjustments and computations before displaying the measurements or waveforms on the screen. Programming is done in Visual Basic. Discussions on the design, considerations and methodology are also inc uded in this paper Different experimentat ons done to test the var ous modules of the system as well as an analysis of the results are also presented. This paper will also touch on how this project differs from some of the previous work in the same area.

PC-Based Instrumentation for Versatile Applications Advantages, Implementation Challenges and Combating Techniques

Personal Computer (PC) based instrumentation has a wide range of applications in the field of education and research. The wide variety, high performance, and reasonable cost of both commercial hardware and software make this platform an attractive choice for instrumentation. Although PC-based instrumentation offers significant advantages, it also has technical obstacles and significant implementation challenges for high-performance test and measurement applications. This paper presents the advantages of PC-based instrumentation and identifies the technical limitations to implement a high-performance system for versatile applications. The methods of combating the inherent problems associated with the PC-based instrumentation have also been presented. The paper suggested an implementation method for PC-based instrumentation which is based on Virtual Instrumentation (VI) technique and PXI architecture. This method enhances the system implementation productivity and lowers the cost thro...

A REVIEW STUDY ON INSTRUMENTATION AND CONTROL ENGINEERING

A REVIEW STUDY ON INSTRUMENTATION AND CONTROL ENGINEERING, 2023

In the present review, instrumentation and control engineering (ICE) is defined as a branch of engineering that studies the measurement and control of process variables, and the design and implementation of systems that incorporate them. Instrumentation and control engineering (ICE) combines two branches of engineering. Instrumentation engineering is the science of the measurement and control of process variables within a production or manufacturing area. Meanwhile, control engineering, also called control systems engineering, is the engineering discipline that applies control theory to design systems with desired behaviors. Control engineers are responsible for the research, design, and development of control devices and systems, typically in manufacturing facilities and process plants. Control methods employ sensors to measure the output variable of the device and provide feedback to the controller so that it can make corrections toward desired performance. Automatic control manages a device without the need of human inputs for correction, such as cruise control for regulating a car's speed. In the present study a comprehensive review study on instrumentation and control engineering have been presented. The study was considered from different viewpoints which includes general introduction to instrumentation and control engineering; a comprehensive instrumentation that deliberates the present subject from the consideration of introduction, historical background and development, applications, measurement parameters, instrumentation engineering, impact of modern development; control engineering from the consideration of introduction, overview, history, control theory, control systems, control engineering education, control engineering careers, and recent advancement; and the last section is the conclusions.

Virtual instrumentation: A practical approach to control and supervision process

This work describes a control and supervision application takes into account the virtual instrumentation advantages to control and supervision industrial manufacturing stations belonging to the modular production system MPS® by Festo. These stations integrate sensors, actuators, conveyor belt and other industrial elements. The focus in this approach was to replace the use of programmable logic controllers by a computer equipped with a software application based on Labview and, together, performs the functions of traditional instruments and PLCs. The manufacturing stations had their processes modeled and simulated in Petri nets. After the models were implemented in Labview environment. Tests and previous similar works in MPS® installed in Automation Laboratory, at UNESP Sorocaba campus, showed the materials and methods used in this work allow the successful use of virtual instrumentation. The results indicate the technology as an advantageous approach for the automation of industrial processes, with gains in flexibility and reduction in project cost.
