Metrology for the Digitalization of Economy and Society

Digitalization is an area, which will very intensively engage and sustainable change the PTB in the long run. Novel measurands in high frequency technology (5G), imaging techniques (e.g. in medicine) and in the manufacturing technologies require fundamental research to ensure trust in such measurements by establishing their traceability to the SI-unit system. Especially for SMEs this simplifies the decision to invest in new digital technologies and enhances their international competitiveness.

A various number of standards and guidelines nationally as well as internationally have to be revised substantially in the foreseeable future, in order to comply the extensive changes of the digital transformation. Here the international importance of the PTB as a competent partner plays an important role in issues of measurement technology and data analysis. Thereby standardization, especially for SMEs are effective means to enter new markets and to enable new digital business models.

Especially in Germany the legal metrology, with its 160 million devices, counts on the major role of the PTB in digital transformation and needs a full and sustainable support. Therefore, the PTB pushes the digitalization of conformity assessment and market surveillance processes by developing a metrological platform, establishing data based services, cutting down innovation barriers and offering reference architectures. In this way, all partners in legal metrology can benefit from the possibilities of the digitalization.

 

The PTB counts on existing cooperations as well as national and international platforms for an efficient networking of legal metrology. At the Berlin Initiative “digital capital” the PTB, for instance, uses a tight cooperation with the local excellent research institutes and networks. Moreover, the PTB is engaged in cooperations with representatives of the “Plattform Industrie 4.0”, the “Labs Networks Industrie 4.0” and many more, to advance the metrology research and standardization. Currently, in the field of digitalization international cooperations are striven with a series of EMPIR-proposals within the scope of the programs of horizon2020.

PTB Digitalization Study 2017

Currently this study is available in a pre-release version. The official study will be published in December 2017 / January 2018 as issue 4.2017 of the PTB-Mitteilungen.

Structure and organisation

The main pillars for PTB, as a supporter of digital transformation in the economy and society, are, in the first place, interdisciplinary cross-sectoral projects:

Metrology cloud – Establishing a trustworthy core platform for a digital quality infrastructure by coupling existing data infrastructures and databases and providing all partners with customized access for digitally upgrading legal metrology.

Digital calibration certificate – Developing a secure and standardized digital information structure for universal use in calibration, accreditation and metrology as well as digitally upgrading the whole calibration hierarchy in the quality infrastructure.

Virtual experiments and mathematics-aided metrology – Developing an interdisciplinary, virtual competence group to metrologically support the paradigm change for the use of simulations and data analysis as essential components of measurement procedures.

Moreover, the metrological research for modern high-frequency networks (5G), the expansion of the quality infrastructure to online surveillance, and the metrological support to digitalized precision production are some of the tasks that will have to be furthered in the long term in the respective departments.

These initiatives are accompanied, coordinated and cross-linked centrally by the working group Opens internal link in current windowPSt1 "Koordination Digitalisierung".

Milestones

End 2017

  • The PTB will introduce a prototype of a digital calibration certificate.

Beginning 2018

  • The PTB will publish a comprehensive concept about the management of research data, which supports the special needs of the research community in the field of reliable freely accessible data according to the Open Data Strategy.
  • Together with the BNetzA, the PTB will work out the metrological challenges and research issues in the section of broad-band measurements and if necessary will announce a research cooperation.
  • The joint professorial chair “Biomedical imaging” in cooperation with the TU Berlin and the Einstein Center will start its work with the main focus on “digital health” and the integration of quantitative image data in biomedical information.
  • Together, the PTB and the British National Physical Laboratory will organize an international workshop of the national metrology institutes (NMI), where the future role of the NMIs in the field of data science will be discussed.
  • The PTB will start a joint cooperation with the company Siemens which focuses on the section “Metrology for industrial IoT” and contains the components “digital calibration certificate” and “reference architectures for cloud computing”.
  • The junior group and cooperated junior professorship “secure and trustworthy net-tied systems” will start their work at the Einstein Center, and based on the existing and broad industry connections, it aims on supporting the increasing digitalization of measuring instruments and measurement methods in legal metrology.

Middle of 2018

  • This junior group is closely linked with the project “Metrology Cloud” which concentrates on conformity assessment and market surveillance processes by developing a common platform, creating data based services and cutting down innovation barriers. The implementation of this project is scheduled for mid-2018.
  • By that time the preparations for the appointment of a joint professorship “Uncertainties and Machine Learning” with TU Berlin are expected to be completed. The aim is to describe the behavior of machine learning methods more proper with regard to data uncertainty, so that barriers of using that methods are cut down.
  • The PTB will start the measurements of systems for the 5G-technologies (e.g. antenna systems and waveguides). Prospectively, these measurements will be implemented into the broad research proposal “Metrology for 5G”.
  • An implementation of an interdisciplinary and inter-divisional competence group for the topic “Metrology of Virtual measurement devices” is planned. It is expected that this group will pick up und push the existing tasks of the PTB in the sections of “digital twins”, “mathematic based measurements” and physical simulation in a holistic approach.
  • The PTB will establish a research focus in the field of “metrology for heterogeneous sensor networks”, which will combine the expertise of the measurement technology and data analyses with the challenges of Industry 4.0 and other areas in an interdivisional and interdisciplinary way.
