At an embedded/Internet of Things (IoT) technology seminar held in Yokohama, Japan last week, Ken Sakamura, the inventor of Japan's self-produced open-ended real-time operating system, slammed Japan's local embedded system designers. Inability to become a promoter of the global Internet of Things (IoT).
As a professor at the University of Tokyo, he has always been a frame-riding thinker, bold and brave, and enthusiastically supports the next-generation computing architecture; most of his academic life is devoted to the development of TRON, and its popularity in Japan. The concept of ubiquitous computing. Yucun said that his "Intelligent Object Network" - similar to the popular Internet of Things - dates back to one of the TRON goals he developed in 1987.
Intelligent Object Network conceived by the village
In the special speech, Mr. Yukun spoke of his disappointment with the Japanese embedded industry community: "Japan has thus allowed Germany to launch the "Industry 4.0" policy and let the US lead the Industrial Internet Consorium ("Industrial Internet ConsorTIum";" Japan's embedded design engineers not only have years of experience in embedded real-time operating systems (RTOS), but also familiar with "ubiquitous computing," but have not tried to dominate the global Internet of Things.
The village further pointed out, and they stood by and let others work hard to define the Internet of Things specifications, and wanted to enjoy the global standard of “winning†in the shortest time; he criticized Japanese engineers for skipping the key procedures for developing standards, and the vision was too narrow. The land only wants to launch commercial products.
The village also mentioned recent exchanges with German engineers: "I was told that Germany has a lot of questions about Industry 4.0 to consult with Japan." He explained that Japanese engineers are obviously looking for a technical standard called Industry 4.0. Not knowing that Industry 4.0 is a German policy; in fact, that is not a technical specification.
Japan: Good at closed, not open, Internet of Things
In his speech, Mr. Yu also talked about the revolutionary changes in the engineering world today from the closed Internet of Things to the open Internet of Things; “The key here is the Internet,†he stressed, as long as the rules continue—TCP/ IP Protocol - Interaction, anyone can connect with any object on the Internet: "No permissions, this is the beauty of the open Internet of Things."
He further explained that openness has become commonplace in any aspect of engineering implementation, starting with an open architecture that extends to open hardware and operating systems, open APIs, and then all the way to open data. For example, once the Internet of Things becomes “open†in Industry 4.0, providing every component necessary for product assembly will require collaboration across the entire path to communicate with unprecedented transparency across the production line.
“You might ask, is this different from the Kanban (instant management) system of the Toyota factory?†said Yucun: “This is actually Toyota’s Kanban. The only difference is that Toyota only allows Toyota’s production. The site became part of the Kanban system."

KOMTRAX, the remote monitoring system of Japanese heavy machinery manufacturer Komatsu, also has similar functions; the observation of the village is: "The difference between Komatsu and GE's attempt to complete with the Industrial Internet Alliance is not so different."
The degree of openness is the difference between KOMTRAX and the Industrial Internet Alliance. Although KOMTRAX can work with Komatsu's own machine tool, its design is not to work with other machine tools or devices in the world. Conversely, GE works with other leaders such as AT&T, Cisco, IBM and Intel to develop technical standards for the Industrial Internet Alliance that anyone in the world can use.
Yucun pointed out that Japanese companies are often conceived in a closed environment, so they are mostly afraid of “opennessâ€; they may be good at closed Internet of Things, but not necessarily for open Internet of Things. . To make matters worse, the Japanese lack the experience of developing “mechanism for governanceâ€.
“Many Japanese engineers misunderstand that “opening†means “doing what they wantâ€;†Yucun said: “They must understand that an open Internet of Things can only happen after we develop rules and incorporate governance.â€
Japanese engineers believe that "making policies" for the open Internet of Things is not theirs, but the responsibility of others. The village emphasizes: "It should not be like this;" Engineers only talk about the technical possibilities of the Internet of Things, but do not participate in the development of deployment. The user context and rules of the open Internet of Things are actually completely unfounded. He called: "It is time to change the Japanese engineering culture."
The future of the Internet of Things is the "aggregation model"
The village also pointed out that if Japanese embedded engineers regard the open Internet of Things as an alarm, they still have not grasped the key point; the future of the Internet of Things that he envisions should be what he calls the "aggregate model". appearance.
Under the so-called aggregation mode, the edge node becomes the real backbone - for example, just a simple sensor; the necessary operations and data processing will be done in the cloud, not the edge device. “Edge devices no longer need to load higher processing performance, a powerful graphics engine to produce a more appealing user interface (UI), and no more memory;†Yucun said: “They will be lighter, so Lower power consumption."
Yucun believes that it is time to rethink how to design embedded systems in the Internet of Things era. Take the familiar digital camera products as an example. The essential elements of natural user interfaces such as image sensors, monitors, graphics engines and other sensing devices - also carried in current cameras - can be broken down into separate Blocks, better UI, digital effects and more powerful image processing will all be combined and integrated in the cloud, not edge devices.
He explained: "Because the cost of communication is getting closer to zero, all this will be feasible." If he is right, the so-called aggregation model will require a great rethinking of the design of embedded systems, especially for Japan. For the embedded design engineer, the traditional skill is to put all the functions into a very small space.
The village is rare in the Japanese engineering community, and its work achievements and prestige spread to a professional outside Japan; he was awarded the ITU150 International ITU Award in May last year, which was celebrated by the ITU. Established on the 150th anniversary, it recognizes outstanding thinkers who have contributed to the achievements of the Alliance.
Also awarded with the awards include MarTIn Cooper (father of mobile phones), Robert E. Kahn (playing a leader in the development of the Internet digital object architecture), and Mark I. Krivocheev (the European Broadcasting Union developing the world's digital TV standard) , the promoter of the HDTV standard), and Thomas Wiegand (to jointly lead the development of the ITU-T H.264/MPEG-AVC video coding standard).
