Abstract
The rollout of smart meters in Europe requires solutions for the transition from the existing metering system to the digital metering infrastructure. Connecting legacy meters to the new digital backends is one of the major challenges for the transitory phase. Here, the requirements for performing valid registration of measurement values from legacy meters are derived from the legal metrological framework of the European Union. Threats on the process of registration are then determined based on these requirements and subsequently evaluated. A prototypical implementation, making use of photo-optical technology is presented, illustrating how applicable requirements may be covered. With the help of a risk assessment, the critical aspects of the implementation are identified to highlight how actual implementations might be further improved.
Zusammenfassung
Die Einführung intelligenter Messsysteme in Europa erfordert Lösungen für einen nahtlosen Übergang zwischen bestehenden Messsystemen und der digitalen Messinfrastruktur. Bestandszähler an neu entstehende digitale Messdatenverarbeitungssysteme anzubinden, stellt eine der größten Herausforderungen für die Übergangsphase des Rollouts dar. Die Anforderungen an die eine rechtssichere Erfassung von Messwerten aus Bestandszählern werden hier aus dem gesetzlichen metrologischen Rahmenwerk der Europäischen Union abgeleitet. Basierend auf diesen Anforderungen werden Bedrohungen auf den Erfassungsprozess abgeleitet und anschließend evaluiert. In diesem Rahmen wird eine prototypische Implementierung auf Basis foto-optischer Mechanismen vorgestellt mit dem Ziel eine Möglichkeit zur Erfüllung der anwendbaren Anforderungen aufzuzeigen. Mittels einer Risikoanalyse des Systems werden die kritischen Aspekte der vorgeschlagenen Implementierung identifiziert und verdeutlicht, wie real existierende Lösungen verbessert werden können.
