FFPA Completes Technical Specifications to Stabilize Various Wireless Communication Systems Co-located in Factory Sites

- A progress toward visualization and integrated management of various information -

Flexible Factory Partner Alliance (FFPA, Chairperson Andreas Dengel) has created the technical specifications that is aiming for various wireless systems co-located in factory sites to operate stably. National Institute of Information and Communications Technology (NICT) has proposed Smart Resource Flow (SRF) wireless platform*1 which has been adopted as architecture for the specifications. By adopting this platform, stable wireless communication is realized, making it easy to visualize and interactively manage various information on the manufacturing sites.

The technical specifications define functions and interfaces to provide framework for coordination and coexistence of wireless systems with different standards, of different generations, and by different vendors coexisting in a same factory site.

An overview of the specifications will be presented at the FFPA seminar, "A vision of future factory sites created with the SRF wireless platform - Introduction of FFPA technical specifications Version1 -" held on October 31 in Tokyo.

[ Background ]

In the factory sites, usage of Information and Communications Technology (ICT) is increasing to enhance productivity by flexible operation releasing constrains of shortage of skilled workers and workstyle change nowadays. Especially for use of wireless commutations, voices from factory sites include:

·Need to monitor conditions of old machines by retrofit wireless sensors.
·Need to remotely monitor and control moving objects, e.g., human and automated guided vehicles (AGVs).
·Need to flexible change processes and layouts of factory sites without costly and time-consuming rewiring of cables.

Wireless communication is indispensable methods to cover these needs. More and more wireless systems have been becoming introduced to accompany manufacturing equipment for status monitoring, product inspection, process management, environment sensing, and machine control, and so on.

There are concerns such as communication instabilities that lead to impact on the current equipment due to interference among wireless systems in unlicensed spectrum where they operate independently and sometimes cannot meet requirements for communications due to degradation of wireless link quality. To address the issues on a technical approach, NICT has proposed the SRF wireless platform to define functions and interfaces among them. FFPA has established since July, 2017 to promote the SRF wireless platform into implementation for use in industries and to make an effort to create the specifications of wireless communications.

[ Achievements ]

FFPA has finalized the technical specifications defining functions and interfaces to pursue commercialization based on architecture of the SRF wireless platform proposed by NICT. The specifications enable wireless communication stabilities, and facilitate visualization and integrated management of various information on the manufacturing sites.

The technical specifications also provide framework for coordination and coexistence of wireless systems with different standards, of different generations, and by different vendors coexisting in the same factory site.

In the architecture of the SRF wireless platform, Field Manager (i.e. coordinator) manages and controls multiple wireless systems consisting of gateways and wireless terminals with coordination (global control).
The features are:
·Radio resources of frequency, time and space assigned to each system by setting control policy,
·Management with cognitive ways of both wireless communications and factory applications, and
·Monitoring wireless environment on the SRF wireless platform.

In addition, each system is allowed to have autonomous internal control based on the control policy to adapt to rapidly local change in wireless environment (local control).

An overview of the specifications will be presented at the FFPA seminar, "A vision of future factory sites created with SRF wireless platform - Introduction of FFPA technical specifications Version1 -" held on October 31 in Tokyo.

[ Future Prospects ]

FFPA is developing test specifications for preparation of certification program starting around in the middle of 2020. It also promotes the spread of the SRF wireless platform that enables visualization of various information on the factory site and integrated management of equipment connected to the network for the use of information and communications to improve productivity.

Formation of Flexible Factory Partner Alliance to Accelerate Use of IoT in Factories

Promoting the spread of coordination control technology to ensure stable communications of various wireless systems

OMRON Corporation, Advanced Telecommunications Research Institute International (ATR), Sanritz Automation Co., Ltd., National Institute of Information and Communications Technology (NICT), NEC Corporation, Fujitsu Limited, and Murata Machinery, Ltd., today announced the formation of the Flexible Factory Partner Alliance (Chairperson: Professor Andreas Dengel of the German Research Center for Artificial Intelligence (DFKI)) to promote the formulation of standards for coordination control technology. This will work to ensure stable communications in an environment where various wireless systems coexist, as well as to promote their use and further accelerate the adoption of wireless systems in manufacturing facilities.

Through the initiatives of this alliance, the partners will seek to meet expectations for a new industrial revolution accompanying the spreading use of IoT in manufacturing facilities.

1. Background and Outlook

In response to fierce international competition resulting from increased globalization, as well as labor shortages and a reduced number of skilled workers due to falling birthrates and aging populations, utilizing ICT in manufacturing to improve productivity is seen as a critical issue. Given that ‘visualization’ in production equipment and production status is moving forward to improve productivity, and as product development cycles have shortened in recent years, there has been a demand for greater flexibility in the configuration of production facilities equipment and in modifying the production line construction. As a means of achieving greater flexibility, there are rising expectations for wireless communications as an important technology. In fact, there has been an increasing trend of manufacturing facilities deploying wireless communications on a trial basis, and then based on these trials, fully implementing such wireless systems.

At the same time, a major issue in wireless communications in factories where various wireless systems coexist is communication instability due to interference between wireless systems and the impact that has on equipment operation. There had previously been few efforts, however, to resolve this sort of wireless communication issue in manufacturing facilities.

To find solutions for the above issues, OMRON, ATR, Sanritz, NICT, NEC, Fujitsu, and Murata Machinery have been conducting trials of wireless communications and evaluating the wireless environment in factories. These companies and organizations have at academic conferences and other venues broadly proposed coordination control technology that would enable stability in communications. This would work by controlling independent wireless systems for each piece of equipment, with specific use cases in actual manufacturing facilities in mind.

Now these companies have come together to form the Flexible Factory Partner Alliance to promote the formulation of standards for coordination control technology. This will thereby ensure stable communications in an environment where various wireless systems coexist, as well as promote their use and further accelerate the adoption of wireless systems in manufacturing facilities. Professor Andreas Dengel of the German Research Center for Artificial Intelligence (DFKI) has been appointed the chairperson of this alliance.

Through the initiatives of this alliance, the partners will work to meet expectations for a new industrial revolution accompanying the spread of the use of IoT in manufacturing facilities.

2. Goals

The goal of this alliance is to contribute to the standardization of technology to stabilize various wireless systems with coordination control, promote the application of wireless communications in manufacturing factories that are expected to accelerate wireless-connected devices to increase productivity, and disseminate the standards.

3. Summary of Activities
