- Extending the Synoptics of Things (SoT) Framework to Manage ISoS Technology LandscapesPublication . Serras, Bruno; Gonçalves, Carlos; Dias, Tiago; F. G. Osório, A. LuísManaging and monitoring the software and hardware artifacts of an industrial organization are fundamental efforts that can often be challenging endeavors to achieve, especially when such technological landscapes are composed of multiple heterogeneous systems. Usually, Internet of Things (IoT) devices are provided by different suppliers and may use different protocols and interfaces. Thus, the integration of these devices results in complex development and maintenance cycles. The Synoptics of Things (SoT) framework can address these problems, in conjunction with the Informatics System of Systems (ISoS) platform by promoting an open market competitive tech nology landscape for organizations. The purpose of the research presented in this paper was to extend the SoT framework in order to manage and monitor the different elements of an ISoS enabled organization, namely the ISystems (Informatics Systems), CES (Cooperation Enabled Services), and Services. We argue that the SoT framework can be essential in a supervisory control and data acquisition (SCADA) system in today’s modern web, by adopting the concept of Web Components as a standard to enable the development of custom and reusable components. We present and discuss such issues in the context of the HORUS system, an informatic system responsible for payment enforcement in fueling stations. In this system, several devices must work in coordination, such as video cameras and video recorders, which are fundamental for the retrieving of license plate images and, therefore, be continually monitored to ensure the correct functioning of the HORUS system.
- Synoptics of Things (SoT): an open framework for the supervision of IoT devicesPublication . Serras, Bruno; Gonçalves, Carlos; Dias, Tiago; F. G. Osório, A. LuísIn the industry, there is a need to manage and monitor systems and their associated devices. This process can be quite complex when the technological landscape is composed of several heterogeneous systems. In such scenarios, both the systems and their devices can be from different suppliers, each one with its own interfaces, often proprietary and non standardized. Moreover, several different administrators can be responsible for the supervision of a system, which greatly complicates the process of supervising multiple systems. Yet, overviewing a technological landscape can be facilitated by the concept of Synoptics, as a fundamental part of a supervisory control and data acquisition system. As modern applications become more and more web based, it makes sense to use web browsers to implement the concept of Synoptics. In this paper, we present the Synoptics of Things (SoT) framework to extend the Synoptics concept to the web domain. The proposed SoT framework explores the concept of Web Components as a standard to enable the development of custom and reusable components for modern web browsers. Such components, or Widgets-IoT, as we call them, can function as an abstraction of both IoT devices and informatics systems, facilitating the interaction with the supervising operators. Accordingly, we present and discuss the use of the SoT framework in an Informatics System of Systems reference implementation to monitor and control the involved systems and the various executive services that compose them.
