This webinar will introduce a way for an open-source time series database, InfluxDB, to be used in IIoT system monitoring.
It will highlight a new architecture that meets the software framework requirements by combining the capabilities of the Data Distribution Service (DDS), a standard from Object Management Group (OMG) for real-time data exchange with InfluxDB.

Making DDS Really Real-Time with OpenFlow

https://dl.acm.org/citation.cfm?doid=2968478.2968479

An increasing amount of distributed real-time systems and other critical infrastructure now rely on Data Distribution Service (DDS) middleware for timely dissementation of data between system nodes. While DDS has been designed specifically for use in distributed real-time systems and exposes a number of QoS properties to programmers, DDS fails to lift time fully into the programming abstraction. The reason for this is simple: DDS cannot directly control the underlying network to ensure that messages always arrive to their destination on time.

Multi-Level Time-Sensitive Networking (TSN) Using the Data Distribution Services (DDS) for Synchronized Three-Phase Measurement Data Transfer

https://ieeexplore.ieee.org/abstract/document/8823854

This paper presents the design and implementation of a Multi-level Time Sensitive Networking (TSN) protocol based on a real-time communication platform utilizing Data Distribution Service (DDS) middleware for data transfer of synchronous three phase measurement data. To transfer ultra-high three phase measurement samples, the DDS open-source protocol is exploited to shape the network’s data traffic according to specific Quality of Service (QoS) profiles, leading to low packet loss and low latency by synchronizing and prioritizing the data in the network.

Autopilot for Robocar

https://secretaria.uvigo.gal/docnet-nuevo/guia_docent/?centre=305&ensenyament=V0…

At the University of Vigo's telecommunications engineering school, students learn the mathematical and physical principles that are necessary to understand telecommunication systems. We also teach them different programming languages, design tools, or in general, how to use computer based and electronic tools to build these communication systems.

In the final year of undergraduate studies, in the subject "Embedded Systems Design", we ask students to design and build a small autonomous vehicle (a quadcopter or a robocar). To do this, they must first create an "autopilot" to manage the information from the sensors, distribute it to the various information processing and decision making systems and finally apply the control commands.

The students build a distributed system in which they use RTI Connext DDS to exchange information between the different blocks of software.

Control Communications with DDS using IEC61499 Service Interface Function Blocks

https://ieeexplore.ieee.org/abstract/document/5641207

The IEC61499 is an open standard for distributed control and automation. The interface between control software and hardware or communications is achieved by means of the so-called Service Interface Function Blocks (SIFB).

Describes the devekopment of UAV Control Station by Raytheon:

  • The control stations provide command and control of an unmanned air vehicle (UAV)
  • A common control station controls more than one type of UAV
  • A control station is made up of a set of service
  • Services defined by the Unmanned Systems (UxS) Control Segment (UCS) Architecture standard. Some common to all vehicles and some unique to a single vehicle

UAV Control Systems belong to a class of systems that require:
