Internet of Things Appears Outbreak Growth Trend

The Internet of Things, according to the definition of the International Telecommunication Union, mainly solves the problem of interconnection between articles, people and articles, and people. It includes not only the related technologies of information exchange and communication between all things, but also the services and applications generated from it. It can be divided into four levels: perception layer, transport layer, platform layer and application layer.

Judging from the overall trend, the Internet of Things is developing rapidly and has great market potential in the future. According to Gartnert, a market analysis company, the number of Internet of Things devices in the world will reach 26 billion by 2020, with the Internet of Things market reaching 1.9 trillion US dollars. In China, the scale of the Internet of Things industry reached 1150 billion yuan in 2017, up nearly 6 times from 170 billion yuan in 2009, showing an explosive growth trend.

Judging from the distribution of enterprises, the world’s leading Internet of Things enterprises are mostly manufacturing enterprises such as network communication and electronic and electrical equipment, while the number of Internet enterprises is relatively small. Researchers found that there were 19 enterprises in the network, communication equipment and telecommunication industry, the largest number, after analyzing the top 50 enterprises in the world’s top 500 Internet of Things in 2018. This was followed by electronic and electrical equipment enterprises (14) and industrial machinery manufacturing enterprises (9). There are only 3 Internet enterprises, accounting for only 6%.

From the perspective of application field, the Internet of Things is currently mainly used in manufacturing, transportation, public utilities and other fields. According to statistics, the global Internet of Things expenditure in 2018 was 77 million US dollars, of which manufacturing was the highest, accounting for 19 million US dollars, accounting for 24.5% of the total, and transportation and public utilities were 11% and 9% respectively. Verizon Telecom found that in 2017, the growth rate of Internet of Things network connectivity was the highest in manufacturing, with 84%, followed by energy and public utilities, transportation and Smart City.

Taking Users as the Center to Create a Good Ecology

According to the industry distribution of Internet of Things enterprises in the world, what are the characteristics of Internet communication enterprises, industrial manufacturing enterprises and Internet enterprises in the construction of Internet of Things?

From the application scenario, the Internet of Things is mainly used to optimize asset management, deepen customer analysis and innovate business models. Schneider Electric digital factory has networked tens of thousands of assets and carried out remote monitoring of assets, Predictive maintenance and optimization of energy consumption. GE Predix connects industrial equipment with suppliers and carries out asset safety monitoring, industrial data management, industrial data analysis, etc. The China Aerospace Science and Industry Group has built an INDICS Industrial Internet cloud platform to support access to various industrial equipment. Through online information exchange and resource sharing, it is pulling off-line intelligent transformation to create a new format that combines O2O, manufacturing services and innovation and entrepreneurship.

From the perspective of application mode, data is the core. Collecting and processing data and carrying out large-scale calculation on it, thus realizing problem diagnosis, rule analysis, cause tracing and future prediction are the main modes of Internet of Things. Amazon Web Services is the world’s largest cloud computing manufacturer, and Amazon’s data center has nearly 3 million servers. Alibaba’s data centers are located in 17 countries and regions including China, the United States, Singapore, Australia, Europe, the Middle East and Malaysia. Google has set up data centers around the world and has set up supporting power stations and optical cables to reduce energy consumption in data centers and improve operating efficiency.

From the perspective of development priorities, there are many Internet of Things platform-level enterprises in China, while sensor-based perception-level enterprises are mainly concentrated in developed countries. For example, Huawei has built the OceanConnect Internet of Things platform, which can realize connection management, equipment management and application enabling management. Alibaba has built the Alibaba Cloud Internet of Things platform, including the development tool platform, application market platform and ICA (Partner Program Alliance) data standard platform.

From the perspective of construction path, most industrial manufacturing enterprises enter the Internet of Things with infrastructure as the starting point, while most Internet enterprises take application as the starting point, but in the end they all take users as the center to create a good ecology. Haier, through the construction of COSMOPlat platform, connects the entire intelligent manufacturing system with the needs of users, and allows users to participate in the whole process of product design and development, production and manufacturing, logistics and distribution, iterative upgrade, etc., so as to create an ecological system in which users, resources and enterprises share a win-win situation. Xiaomi Ecological Chain plans to push backward from the entry of mobile phones, homes, bracelets and other application terminals, and gradually open up links such as connections, platforms and chips.

Energy Enterprises Should Use Advantages to Expand Blue Ocean

What are the characteristics of energy and power enterprises in the process of building the Internet of Things?

On the basis of development, energy and power enterprises have the natural advantages of power system automation and have achieved good results in the primary application of the Internet of Things. Singapore Energy Company has set up SCADA, asset equipment management FMS, etc. to monitor 80% of the state of the power grid, saving about 260 million RMB per year. The oil pressure on-line monitoring system has been built to control the cable operation at any time and realize the new use of a large number of old equipment such as Oil filled cable, which has achieved remarkable effects in reducing operating costs and effectively preventing accidents.

From the application scenario, energy and power enterprises mainly use the Internet of Things to carry out equipment monitoring and management, smart meter data analysis, new energy monitoring and optimization, commercial value mining, etc. TEPCO has installed sensors in power generation facilities such as steam turbines. Through the Internet of Things Remote Optimization Center, it can remotely monitor, detect abnormalities and manage thermal efficiency of the power station. It can reduce downtime and overhaul by 10% ~ 20%, saving millions of dollars in fuel costs for thermal power business every year. Electricite de France has deployed Linky smart meter system to carry out in-depth development and application of non-metering functions to detect, quickly locate and isolate low-voltage faults in distribution networks. Edison Electric uses the full stack Internet of Things development platform to develop customer service and commercial value for 5 million smart meter data.

Judging from the application level, most enterprises are still in the stage of performance verification, platform construction and scattered demonstration application, and have not yet formed the top-level design and system promotion of the power Internet of Things. In addition to Tokyo Electric Power Company’s relatively sound physical network system in the power generation field and its system design and commercial application, most enterprises’ application of Internet of Things is still in a scattered state. E.ON focuses on the research and development of intelligent sensing instruments, home energy management systems, and monitoring and analysis of wind farm data. Electricite de France focuses on the layout of Internet of Things hardware such as smart meters and low-power wireless network services.

From the perspective of development mode, energy and power enterprises attach importance to high-quality data analysis and decision-making transformation, and generally adopt cooperation with advanced communication and information technology enterprises to speed up the construction and application of the Internet of Things. Electricity has the physical characteristics of instantaneous completion of production, supply and marketing. Information perception, transmission and real-time control for power grid operation are relatively sound, but high-quality analysis of information and accurate decision-making transformation are the main pain points.

On the whole, the Internet of Things is developing rapidly with great potential and is a blue ocean for future development. At the same time, due to its relatively short development history, there are still some problems such as uncertain investment income, single business model, inconsistent standards and norms, and relatively lack of professional talents. At present, most of the Internet of Things is still in the stage of small-scale demonstration and verification, and there is still a big gap from systematic and large-scale commercial applications. For power grid enterprises, opportunities and challenges coexist.

In the future, on the premise of top-level design, power grid enterprises should carry out demonstration projects to explore and expand the application of the Internet of Things in substation management, material Purchasing, comprehensive energy services, distributed energy, customer behavior analysis, etc. Strengthen data management, analysis and application, and improve the large-scale processing capacity of data; According to Energy Internet’s requirements for data scale, precision and speed, research and development of suitable sensors, chips and other key equipment will promote the transformation and upgrading of the industry.
