Process informatics

from Wikipedia, the free encyclopedia

Process informatics (or process data processing ) is the science of observation, control, regulation (including diagnosis), monitoring, optimization, visualization and logging of technical processes with computers. On the one hand, it is part of applied computer science and, on the other hand, cybernetics (control technology) in general and automation technology (measurement, control, regulation) in particular. It can be understood as the intersection of applied computer science and automation technology. From the user's point of view, process informatics is a sub-area of computer science that deals with applications in automation technology or the natural sciences . The computer is used for the modeling , simulation or automation of technical and / or scientific processes . Process informatics is therefore also related to industrial information technology (industrial IT), which is about information acquisition, distribution and processing. The knowledge area arose from the knowledge areas of automation technology with the sub-areas of measurement , control and regulation technology , process computing technology , simulation technology and real-time programming. It is closely related to applied computer science .

Since computers have now become an important tool in specialist areas such as system analysis and control engineering, many areas of control engineering are migrating to process informatics or process automation. The computer is the most economical alternative and an essential tool for system analysis, modeling, simulation, hardware-in-the-loop simulation, automation, control and regulation of technical and scientific processes, process monitoring, diagnosis and visualization. The area of ​​process control technology can also be subsumed under the term process informatics.

In contrast to IT, process IT always involves real-time processing of the signals, i. H. simultaneous and timely processing of the data and provision of the results play a crucial role. Then there is "digitization", i. H. the amplitude and time discrete representation and calculation of actually analog and continuous process variables. The z-transformation has proven itself for the mathematical representation .

The independent new areas of knowledge created by the triumph of the computer since the 1960s, such as digital signal processing, digital filters, and digital control, can also be summarized under the heading of process informatics.
