Digital Twins

This component implements the Digital Twin concept using the semantic model based on the Web
Things API (Mozilla). It facilitates the auto-generation of the code of the twins to be deployed at
the edge in Javascript format and provides a broker (Digital Twin Broker) for its connection with
the cloud. The extension with Flow Engine allows defining collaborative twins environments in the
cloud.

Edge Engine

Edge Engine is Minsait’s commitment to build a rich architecture of containers at the edge that
permits data to be processed wherever it is generated. Edge Engine increases response speed and
data security while reducing communication costs. It provides the tools to manage the component
life cycle, as well as a set of useful protocols and services.

Workload Consolidation

The Unified Hybrid IoT Framework for Industry, based on Kubernetes distributed clusters, is a
management tool for real-time computational support in plants with heavy operation workloads
. It allows the deployment and management of automation acquisition elements through RF and
wired networks as well as the use of ML algorithms with low latency.

Programming languages

The platform is designed mainly in Java (Spring Boot). But the following languages can be used
to interact with the platform:

• Dashboards – JavaScript, angular, html5, css3.

• Flow engine – JavaScript.
• Streamsets – JavaScript and sql.

• Notebooks – spark, r, python, sql.

5.4 Set of operational IT solutions for integrated city management

The axes and actions of the Smart Logroño project are the following:

1 Internal Axis aimed at municipal services:

• Dissemination, promotion and implementation of the “smart culture” that fosters a change in
the service management model based on efficiency and re-use of resources, the evaluation
and monitoring of indicators and the use of georeferenced capacities.

• Development of the different vertical and thematic projects identified in the Master Plan.
