Rainer Winz

Rainer Winz (born February 1, 1950 in Duisburg ) is a German engineer and professor of process data processing and operating systems .

Life

Rainer Winz was born in Duisburg. His father Rudolf Winz worked as a representative here, his mother Christel Winz as a secretary. Here he attended a primary school since 1956 and then the Steinbart-Gymnasium , where he passed his Abitur in 1968 .

After completing military service in the Air Force, he began studying electrical engineering at the then newly founded Faculty of Electrical Engineering at the Ruhr University in Bochum in 1970 and obtained his intermediate diploma. He then switched to studying theoretical electrical engineering at the TH Darmstadt , and here he also attended courses on automation technology with Winfried Oppelt , who is one of the fathers of control engineering in German-speaking countries. Winz obtained his degree in engineering in 1975 .

He gained his first professional experience as a commissioning engineer for industrial plants in the well-known electrical company Brown Boweri & Cie , which later merged with the Swedish electrical and robot company ASEA 's second largest electrical engineering company ABB alongside Siemens developed in the German market. At that time, it was already being used on an international level in South Africa in the industrial region of Johannesburg when the electrically operated blast furnace fan with a 30 MW synchronous motor was commissioned at ISCOR Steel Vanderbijlpark, which was used for the first time in this country .

He obtained his doctorate in 1979 after being supervised by Wilhelm Müller at the TH Darmstadt with the development of a method for the numerical solution of Maxwell's equations with the grade “summa cum laude”. This was the first time that the problem of non-linear, 3-dimensional equations was solved numerically using modern computing technology. With his work results, Winz opened up new ways for the technical application of the Maxwell equations, especially for the design of electrical machines in the higher performance classes.

Electrical and automation engineer in industry

After completing his dissertation, Winz went into industry. Starting in 1979, he initially worked as a project manager for the Eckelmann Industrieautomation group of companies , which, as a traditional medium-sized company, goes back to company founder Gerd Eckelmann . Later he took on the role of technical director of the subsidiary in Wiesbaden in the group of companies.

One focus of his activity was the development of process computers , with his own hardware solutions and the associated software being created. The applications of these process computers for plant automation were mainly carried out as initial use in the manufacturing industry. The following are to be highlighted as examples:

  • Development of process computers (hardware and software) that control and regulate time sequences and process steps in accordance with the NAMUR guidelines, especially for the chemical and process industry. In doing so, he took up ideas that go back to Martin Polke .
  • Development of industry solutions with the integration of recipe-controlled weighing and mixing regulations with the Gustav Eirich machine factory for the glass industry, refractory industry, sand processing in foundries, concrete mixing plants and sand-lime brick plants.
  • Development of the automation technology requirements for the special requirements of the ceramic industry, so that ceramic technologists can specify the draft control, temperature profiles and reduction zones without programming knowledge.
  • In response to ever stricter environmental regulations, the development of process computers especially for vacuum mixing technology; Integration of temperature control and material preparation, and no more emissions of solvent vapors by controlling a closed cycle of solvents.
  • Replacement of analog control technology in cold and hot rolling mills with process computers based on Multibus II with real-time multitasking operating system iRMX at SMS-Schloemann-Siemag and the Austrian plant manufacturer Voest-Alpine , around 40 end customers, e.g. B. Arcelor (Lorraine), NUCOR Steel (Indiana), Eisenhüttenstadt cold rolling mill.
  • Development of computer-aided medical diagnostic systems at Boehringer Mannheim .
  • In 1985 Winz participated in the commissioning of the automation system for the mixing and weighing technology in a glassworks in Luoyang, People's Republic of China. This was the first production facility in China for windshields for the automotive industry. Therefore, compared to normal window glass, significantly higher requirements for the automatic control with regard to the accuracy of the weighing and the homogeneity of the processed mixture had to be met, which on the one hand placed higher demands on the commissioning team, but at the same time meant a high level of professional experience for Winz on an international level.

In 1996, Winz also worked for the Munich securities printing company Giesecke & Devrient in the field of chip card technology. Experience in another area of ​​process data processing has grown from this work.

Professor for process data processing

University of Merseburg - main building on campus

In December 1996, Winz was appointed Professor of Operating Systems and Process Data Processing in the Department of Computer Science and Applied Natural Sciences (INW) at the University of Merseburg in Saxony-Anhalt (Rector: Johanna Wanka ).

The university teaching of Winz including in particular lectures in the areas of operating system technology, Data Processing, Computer Integrated Manufacturing (CIM), real-time operating systems and fundamentals of microprocessor technology for electrical engineers, physicists and mechatronics. He also played a key role in the training of graduate engineers in the rather rare specialization in automation systems for process engineering processes in the German-speaking region .

In cooperation with his professor colleagues Werner Kriesel , Frank Sokollik , Peter Helm and Tatjana Lange , internship facilities at the level of industry-related automated systems for process engineering and air conditioning have been created, which represent a unique selling point compared to comparable university institutions in German-speaking countries and are also used for research work. This also resulted in close specialist contacts with Dominik Surek , the head of the Affiliated Institute for Fluid and Pump Technology (FPT), and he also cooperated with mechatronics engineer Manfred Lohöfener , who was later elected dean of the INW department.

As a university professor, Winz worked on a number of fields of science in his research . He developed an independent, industry-related research activity with several partners. Practical solutions were developed for novel processes for computer-based regulation and control, which were also used on the specially created, industry-oriented, highly automated systems for endurance testing. Particularly noteworthy are:

  • the development of a fast multitasking kernel with task change times in the small nanosecond range
  • the development of a method to avoid deadlocks in multitasking real-time systems with low overhead during runtime (40 microseconds on an 800 MHz Pentium processor).

Since 2009 he has been working on a comprehensive compendium of renewable energies in collaboration with the book publisher of the Frankfurter Allgemeine Zeitung (FAZ) and the Fraunhofer Energy Alliance . Here he works as an author as well as coordinator of the scientific articles and as co-editor.

In addition to national and international specialist lectures, his scientific publications include participation in several book publications and over 25 articles in specialist journals. During his professorship, he supervised more than 100 graduation theses for degrees in engineering, bachelor and master degrees.

Winz was involved in the university's academic self-administration : he was a member of the Academic Senate for three terms (2001–2013), another three terms (also 2001–2013) he worked on the faculty council, and one term (1998–2000) in the university council. In the Senate, he was involved in the restructuring and amalgamation of departments and in particular in the integration of the potentials of electrical engineering, computer science and mathematics to raise the profile of the university. In the council he participated in the development of a new basic order of the university, in particular he actively worked towards the streamlining of responsibilities. However, he soon realized that the council did not have permanent tasks, and so he successfully campaigned for the council to be abolished.
