Friedrich Schneider (2015)

Friedrich Schneider (born September 19, 1937 in Berlin ) is a German engineer and professor of measurement and control technology . He introduced the process computer to measurement and automation technology and used it in widely branched networks ( telecontrol systems , field bus systems ).

Career

Friedrich Schneider was born in Berlin in 1937 as the youngest of three children. His father was a graduate engineer in electrical engineering . After graduating from the Luitpold-Oberrealschule in Munich, Friedrich studied electrical engineering at the Technical University of Munich , now the Technical University of Munich (TUM), from 1956 . During and at the end of his studies, he did industrial internships at AEG, the North of Scotland Hydro-Electric Board , Urray (Scotland) and the Long Island Lighting Company, Hicksville, NY, USA .

After graduating from the Technical University of Munich in 1962/63, he expanded his knowledge of control engineering with the help of a one-year scholarship from the DAAD at the University of California, Berkeley, and obtained a Master of Science degree in the USA .

After returning from the USA in 1964, he became a research assistant at the TUM Institute for Measurement and Control. Here he introduced the analog and digital computer to teaching and research at the institute. He did his doctorate in 1969 under Ludwig Merz with the topic: "Setting the adaptive control of processes using digital computers". In 1970 he completed his habilitation at TUM with the subject: "Digital computing methods in control engineering" for the subject of control engineering .

Industrial activity

From 1970 to 1983 Schneider was employed by AEG-Telefunken, automation systems in Seligenstadt (Hessen). At AEG-Telefunken, he first set up a software department for systems for recording faults in power plants, for recording measurement data in production processes and for monitoring water and wastewater systems. For this purpose, micro-process computers were used, for which the entire software was developed, starting with the real-time operating system, through the acquisition and processing of measured values, to the log output.

In the period that followed, the telecontrol systems for monitoring and controlling widely distributed processes were digitized. At first the telecontrol center was replaced by the process computer and later, with the advent of the microprocessor, also the substations. Schneider made valuable contributions here for the development of large-scale telecontrol networks with a hierarchical monitoring structure and integrated redundancy concepts.

The number of measuring and control points to be monitored went into the thousands when monitoring equipment in large systems (e.g. in automobile factories). In order to make this manageable, computer-aided project planning aids had to be created under his leadership. The replacement of the impressive, huge waiting areas made of mosaic blocks with color vision devices for human-machine communication also represented a major technological step in which Schneider played a key role.

For the development of the necessary software on all automation levels, engineers with IT knowledge as well as IT specialists with an understanding of technology were required; in Germany the job market was swept empty for this. Schneider managed to recruit the necessary staff in Great Britain.

Before moving to the university, Schneider was most recently in charge of the “Telecontrol Technology Subsystems” department, where he was responsible for around 100 employees, primarily engineers and IT specialists.

Activity at the university

During his industrial activity, Schneider held a lecture on automation systems as a private lecturer in the summer semester.

In 1983 he was appointed professor for measurement and control engineering at TUM. His lecture "Measurement and control engineering including internship" was a compulsory subject for all students for teaching at vocational schools, specializing in electrical engineering. In his diploma course, Schneider gave lectures on automation systems, most recently on "Local and Distributed Measurement Networks". Schneider has offered the compulsory subject “Environmental Measurement Technology” for the “Environmental Technology” postgraduate course for students with a diploma. For all mechanical engineers in the 2nd semester, Schneider held the introductory lecture in computer science , which was offered for the first time for several years .

In research , Schneider, together with diploma and doctoral students, has made a number of contributions to the transmission of measurement data and processing of measured values ​​with bus systems. Under his leadership, an automation system based on transputers was designed and implemented, which was ultimately used in a highly dynamic exhaust test bench at BMW. The special feature of the transputer is that it allows parallel processing of measurement data on the chip.

Fieldbus systems for the serial connection of sensors and actuators on site were a focus of his research work, most recently the aspect of the transmission of safety-relevant data (safety) via a fieldbus.

Schneider set up working groups for home automation , in which building system technology and software engineering were the main focus areas. In a demo house, which was made available by VISION WOHNEN Objekt GbR, the implemented hardware and software could be checked for practicality. Together with the chair of Hans-Rolf Tränkler and a number of industrial partners, several joint home automation projects have been acquired from the BMBF, the Bavarian Research Foundation and the German Environmental Foundation. In the tele-Haus project, the Schneider working group implemented not only the overall software, but also topics such as person and presence detection, system-integrated device protection and an intelligent adapter. As part of this research, Schneider supervised 120 diploma theses and 14 doctorates .

At the university, he was the foreign representative of the faculty, chairman of the diploma main examination board and member of the faculty council. In addition, he was a member of the Association of German Electrical Engineers (VDE), where he headed the specialist committee “Basics of Measurement Systems” in the Society for Measurement and Automation Technology (GMA).

Activities abroad

Shortly after German reunification , the EU initiated the TEMPUS programs, which helped to establish cooperation with universities in the Czech Republic, Hungary, Slovenia, Estonia and Romania. This included the exchange of students and graduate students as well as longer stays for professors. Schneider was the contact person for the Faculty of Electrical Engineering and Information Technology.

Together with Professors Elmar Schrüfer (TUM) and Hans-Rolf Tränkler (University of the Federal Armed Forces, Munich), Schneider set up the East Scholarship Program . As part of this program, graduates from Eastern European universities, in particular from the Czech Republic, Ukraine, Russia and Slovenia, can carry out their diploma theses for six months in the laboratories of Munich universities. This program is financed from third-party funds. 70 students had benefited from this program by 2004.

Within the framework of the SOCRATES / ERASMUS programs of the EU, partnerships have been developed with universities in France, Great Britain, Italy and Spain, among others, through which many foreign and German students can spend at least one semester abroad. The supervision of the students often resulted in closer scientific cooperation. Double degree programs have been agreed with French universities in particular.

Through the network network GE4 (Global Education Exchanges for Engineers and Entrepreneurs), Schneider placed 5 TUM students in the USA every year. With the help of GE4, the US61 / EC111 project "Developing a New Generation of Transatlantic University and Industrial Partners" between 7 US and 7 European universities was created between 1996 and 1999 with Schneider as project manager on the European side. Together with Elmar Schrüfer (TUM), Schneider established contacts with universities in the People's Republic of China, including Tsinghua University in Beijing and Tongji University in Shanghai , where Schneider gave block lectures at the Chinese-German University College (CDHK) . From 2005 to 2008 Schneider was the specialist coordinator for the electrical engineering branch.

Thanks to the personal union as chairman of the diploma main examination board, as foreign representative of the Faculty of Electrical Engineering and Information Technology and as ECTS representative (European Credit Transfer System), Schneider was able to recognize the study achievements made abroad at the TUM without bureaucratic difficulties.
