What is the meaning of IoT?Explain the mechanism of technology that changes society in an easy -to -understand manner
IoT is a mechanism that connects various things to the Internet.
A comfortable life with a familiar smart home appliances and smart speakers have realized a comfortable life.IoT technology is used for products that meet the needs of these eras.However, even if you use products, many people don't know much about IoT.
In this article, I will explain how the society changes depending on the meaning of IoT and IoT technology in an easy -to -understand manner.
What is IoT?
As described at the beginning, IoT is a mechanism that connects various things to the Internet.The Internet makes our lives convenient by collaborating with things and things.
The number of IoT devices in the world is increasing year by year, and the increase in medical care, industrial applications, and cars is expected.
In March 2020, a new commercial service for the 5th generation mobile communication system (5G) has been launched.5G has the features of ultra -high -speed communication, ultra -low delay communication, and many simultaneous connections.By changing from LTE or 4G to 5G, it can be expected that the IoT of society will develop more rapidly than ever.
How to read IoT
The reading of IoT is "I Oti".This is an abbreviation of Internet of Things.
Meaning of IoT
IoT means "Internet of things"."Things" here are specifically "all things".Until now, it was a computer, smartphone, and tablet terminal for things that were connected to the Internet.However, at present, everything and everything can be connected to the Internet.Home appliances such as air conditioners that can adjust temperature on the go and vacuum cleaner robots that automatically clean are already put into practical use and improved convenience.
Maybe a world where the Internet is connected to clothes and furniture will come in the future.
"M2M" is similar to IoT.This word is an abbreviation of "machine-to-machine".It refers to how to exchange information between equipment.
From the late 1980s to the first half of the 1990s, there was the word "ubiquitous computing".The construction of the ubiquitous network, which is currently progressing, is expressed by the word IoT.
IoT market size
According to the IDC JAPAN report, for user spending in the domestic IoT market, the track record (expected value) in 2020 was 6,312.5 billion yen.It is expected to reach 10,190.2 billion yen in 2025.
By industrial field, assembly and manufacturing, process manufacturing, government agencies, public / public interest, retail, and transportation are increasing.In particular, the manufacturing industry has a large proportion of GDP, so it seems that IoT is promoted as a national policy.
Social mechanism brought by IoT technology
The IoT allows you to automate and efficient by entrusting the simple tasks that you need to do so far to the machine.For example, in agriculture, the sensor can detect the temperature, humidity, CO2 concentration, etc. and get data.If you analyze the data and have the machine work automatically, you can grow agricultural products efficiently.
If things exchange with IoT, this optimization is possible.While sleeping, the efforts of robots to harvest crops are already being carried out.
In this way, IoT seems to play a role in solving the shortage of human resources.
What is IoT technology?
Here, we assume a mechanism that allows people to connect sensors and driving devices that open and close pumps to the network, such as the use of IoT in agriculture described earlier, so that people can confirm the results as a report from remote areas.I will explain.
デバイス技術
Device technology begins with grasping various data.A control device to collect data is required using a sensor according to the data you want to get.
For example, combine microcomputers and sensors such as Raspberry Pi and Arduino like Lego.It may seem difficult, but it is easy to use in a programming class for children.
Taking smart agriculture as an example, IoT is often installed outdoors, so it is necessary to consider the natural environment such as rain and dust.It is also necessary to pay attention to battery operation considering power consumption.
ネットワーク技術
Network technology centrally manage and analyze the data collected on the device on the server prepared on the cloud on the Internet.Therefore, it is necessary to send and receive data from the device to the server via the network.Devices equipped with sensors may be installed beyond the scope of short-range wireless networks such as Wi-Fi and Bluetooth, which relay conventional wired and wired.Therefore, it is necessary to consider the use of technology through the network of mobile telecommunications companies such as 5G and LTE.
Sakura Internet offers an IoT SIM service called "Sakura's Secure Mobile Connect".By using the SIM on your device, you can use a secure network on an LTE closed network that does not go through the Internet from SIM to Sakura cloud.
データ処理技術技術
Data processing technology manages the data collected by the device and is used in data analysis.Since it is necessary to prepare an environment where collected data can be managed in one place, we generally build an IoT system using cloud services.
Efficient use of large amounts of data requires big data analysis technology.Since human power has a limit, it is important to use AI technology such as machine learning and deep learning to analyze and analyze on computers.
セキュリティ技術
IoT devices are often exposed to cyber attacks due to the difficulty in managing, and the performance of the device is limited and the appropriate security measures cannot be applied.This is a major issue, so it is necessary to strengthen measures.
Sakura Internet IoT services provide a closed network that does not go through the Internet.The communication route is safe because it is protected by strong security.
In connection with closed networks, Sakura Internet has a service for local governments nationwide called LGWAN Connect.LGWAN is a closed network that is separated from the Internet and maintains advanced security.For LGWAN, see "What is LGWAN? Explain the reason why it is essential for local government businesses in an easy -to -understand manner."
Regardless of IoT, security measures are important.For more information about security, see "What is cyber security? Explain the necessity and risk evaluation based on the basic law and management guidelines ( * Move to ITM's corporate site)".
A society where IoT technology spreads
The introduction of system services such as IoT and AI was announced in the "Communication Usage Trend Survey" announced by the Ministry of Internal Affairs and Communications.As a result, 69.It has become clear that 8 % of companies have not introduced IoT.
This survey also announced the effects of the introduced companies."It was very effective" 19.5 %, "It was effective to some extent" 61.At 5 %, you can see that more than 80 % of companies have realized the effect.From this result, IoT technology is effective in business.
With the expansion of infectious diseases, the need for digital transformation (DX) promotion using IoT technology has been recognized again.
IoT technology greatly changes our lives.It has already been used in everyday life as a wearable device such as cameras and smart watches.In the future, automatic delivery by drones and automatic driving cars may be realized.I can't wait to be developed.
IoTの活用事例
Introducing examples of using IoT by the manufacturing industry.Okaya Heat Treatment Industry Co., Ltd. also checked the operation of the heat treatment furnace at night.However, it takes time, burden, and cost.Therefore, we introduced an IoT mechanism that allows you to grasp the operation status in real time even from outside the factory.
Remote surveillance allows early response and remote control to be safe, and heat -treated furnace can be stopped even in case of emergency, such as when abnormalities occur.(Reference: Ministry of Economy, Trade and Industry small and medium -sized manufacturing companies IoT, etc.
IoT単体では成り立たない？IoTの仕組み
By understanding the connection with the cloud, you can see the overall image of the mechanism.When an IoT device is connected to the Internet, the cloud will be used.
Cloud is a computer system that users use via the Internet and other factors, and are also called cloud computing and cloud services.
The cloud accumulates and analyzes the cloud.IoT services are not established by IoT alone.It is established by combining with technology such as cloud, big data, and AI.
Sakura Internet also provides IoT services.That is the IoT platform service using Sakura's cloud and IoT.
IoT summary
The use of IoT can improve productivity.Why don't you take advantage of these technologies and work on the realization of digital transformation (DX)?
