#01 Achieving digital transformation Technologies for realizing SPINEX design concepts Shuji Yamamoto Chief Specialist Product and Service Marketing Div. Toshiba Digital Solutions Corporation

Since first being made commercially available, Toshiba's SPINEX IoT (Internet of Things) architecture has been extremely well-received by a variety of customers in the industrial and social fields, and has been used in the field to resolve problems using the potential of the IoT. Our mission is to apply SPINEX design concepts digital twins, edge computing, and open partnerships to various operational issues, producing effective solutions that accelerate customer innovation. This is achieved by processing, analyzing, and leveraging time-series data collected from IoT networks in factories and in the field. We provide greater security for the massive collections of data used in these solutions while creating new value which spans company and industry lines. Let's look at some of the notable products, services, and measures that make up the SPINEX platform for producing new value from the worksite.

Worksites leveraging SPINEX

This spring, the Ministry of Economy, Trade and Industry announced the new Japanese industrial policy concept of “Connected Industries.” Work is underway in reflecting this concept in concrete measures. For Germany's “industrie 4.0” national project and the U.S. “Industrial Internet,” concrete architecture and system creation began from the policy conceptualization stage, and these activities are accelerating. We are now at the stage where corporate and societal reforms which leverage the IoT need actual implementation in the field, not mere concepts.

A critical part of field-level implementation is the systematization of practice-based expertise and architecture. Overall architecture (including services), which encompasses business information usage and operation, is designed, and not only are standards and de facto standards used, but open partnerships are thoroughly leveraged to achieve the results that are possible through collaboration. Our core technologies and products are then used in areas which require the technologies and features that Toshiba can provide.
Toshiba systematically merges advanced technologies such as IoT, cloud, and AI (Artificial Intelligence) technologies, with its extensive practical experience and expertise, cultivated in the field in a wide range of businesses such as semiconductors and social infrastructure. This is supplied in the form of the innovative IoT architecture “SPINEX.” Toshiba provides powerful support for customer digital transformation.

SPINEX's features include its use of “digital twins,” which digitally replicate site activities and environments in real-time, “edge computing,” which performs real-time edge (site) processing and collaborative processing with the cloud, and “media intelligence”, which is the technology for knowledge processing utilizing speech and images, developed through Toshiba's long years of experience to support communication between human and machines. These technologies are used to sense and analyze site data. They are core technologies that are leverage these data in operations, and are shaped by a precisely defined architecture of advanced technologies based on site use.
Since before the announcement of SPINEX in November 2016 Toshiba has engaged in leading overall architectures, such as developing and improving the products and services used in SPINEX by providing big data platforms combining middleware products and services, and by developing improved security. These platform technologies and technologies developed by our global partners, have made it possible to connect all types of information, people, as well as diverse products, services, and technologies, in real time (Fig. 1).

Unique middleware and databases supporting data collection, storage, and analysis

Edge computing is a method for processing massive collaborative distributed data, such as time-series sensor data, images, and videos, between edges (sites) and the cloud. This method reduces network loads while improving the immediacy of site data processing and state detection.
Toshiba has developed SmartEDA, a data collection and event processing solution which is effective for implementing edge computing. SmartEDA can be placed on site controllers and gateways to collect large amounts of data from devices and sensors and performs initial data processing. It can detect real-time abnormality and control site device and equipment autonomously, as well as forecast sign detection of imminent system failures. It can also identify abnormal values, immediately sending this data to the cloud while sending problem-free data at regular intervals. This freely configurable transmission control reduces the network loads while performing data editing aligned with user needs, supporting collaborative distributed processing.

Digital twins together with edge computing are the central elements that support digital transformation by SPINEX. Large amounts of collected data are used to accurately reproduce real-world events in digital representation in real time (mapping). For example, conditions within a plant can be accurately monitored, and signs of production line delays, stoppages, and product defects are rapidly detected, enabling prompt improvements. Thus production site productivity and quality are dramatically improved.
The key issue is how to best store the explosively increasing sensor data and process it efficiently while accommodating the specific characteristics of individual customer operations and changes in their environments. Toshiba has developed and released GridDB, a high-speed, scalable data management solution optimal for representing phenomena and identifying signs of issues through the use of digital twins. GridDB uses a unique IoT-oriented data model appropriate for managing time-series data and three-dimensional spatial data, ensuring data consistency on a per-container basis. Necessary data is placed not only in storage media but in memory as well, and is processed efficiently. Its overwhelming scalability, allowing capacity and performance expansion simply by adding servers, has been proven by third-party benchmark tests. Toshiba provides GridDB globally as open source software, and it is even being used in verification testing at a US university.

* GridDB is introduced in detail in #03.

An industrial big data solution that accelerates site action

Toshiba provides a big data solution to ensure that the big data accumulated through the implementation of edge computing and digital twins is smoothly tied into action on work site.
In addition to SmartEDA and GridDB, the GridData analysis solution performs high-speed processing across large amounts of both internal and external data of a corporatation. GridData applies open, industry-standard analytics technology and cutting-edge algorithms, with Toshiba's unique event pattern analysis technology and AI at a high level. Thus all-in-one support for “collection -> storage -> prediction and analysis -> visualization -> utilization” processes is performed. These technologies are backed by the Toshiba Group's experience through using big data in semiconductor plants and other worksites. Inference engines are run in the edge sections, near devices, to flexible collect, edit, and convey sensing data, providing functions aimed at achieving even more advanced, truly edge rich platforms.

Multilayer security protection for open systems

Even in environments poised to receive the full benefits provided by SPINEX, when we apply results to business, the security of control systems, which increasingly use multi-device, multi-cloud connectivity and are increasingly open, is important.
Toshiba has extensive technologies developed from minute semiconductor products to large industrial machines, experience of the construction and operation of critical control systems used in social infrastructure, and operation expertise regarding the information systems that have provided to over 200,000 employees with hundreds of thousands of information devices through years. We leverage these experience in the development and operation of security systems for use with the IoT. Of course, we are also at the forefront of deploying and using the latest software, hardware, and solutions for combatting cyber-attacks, both in Japan and abroad. We provide OT (Operational Technology) security solutions that offer multi-layer protection from cyber security threats for edges such as devices and IoT gateways, as well as networks, clouds, and entire systems.

By using optimal security design based on risk assessment form the IoT system design phase, we provide SPINEX with safety that extends from devices to clouds. We provide support for secure data collection, storage, analysis, and action, engage in open and active corporate collaboration, and contribute to greater competitiveness by leveraging a diverse range of data.
