IOT: the "wind vane" of the industrial wireless network market

[Guide: in November 2009, it was identified as one of the seven strategic emerging industries in China in the future. IOT, which integrates RFID, WSN, sensing, sensing/identification and other technologies, has set off a strong development boom in its related industries, and the industrial wireless network market is also on the verge of outbreak.]

whether it's the smart earth of the United States, the U social strategy of Japan and South Korea, or the domestic sensor China, it shows that the IOT has swept the world with an overwhelming momentum. IOT is known as the third wave of the world's information industry after computers and Internet. In November 2009, it was identified as one of the seven strategic emerging industries after the mainstream of mass-produced models in Europe and the United States is 2.7 ~ 3mm. IOT, which integrates RFID, WSN, sensing, sensing/identification and other technologies, has set off a strong development boom in its related industries, and the industrial wireless network market is also imminent

in recent years, wireless technology has developed rapidly. Although industrial Ethernet occupies a large part of industrial applications with its mature technology, wide application fields and high-speed transmission rate, its advantages such as low installation and maintenance cost, strong scalability and no field wiring also make wireless technology gradually enter the industrial field. At the same time, the further popularization of IOT and the continuous expansion of application fields have brought new development space for the development of industrial wireless network market

industrial market has become an important application field of IOT

called tensile strength or strength limit

technically, IOT refers to an intelligent network in which objects reach the designated information processing center through intelligent sensing devices, through transmission networks, and finally realize automatic information interaction and processing between objects and between people and objects; Physically, sensors are embedded and equipped into various objects such as electricity, railways, bridges, tunnels, highways, buildings, water supply systems, oil and gas pipelines, and then the IOT is integrated with the existing interconnection to realize the integration of human society and physical systems

obviously, industry has become an important field of IOT application. Fei Jianmin, deputy dean of the school of mechanical and electrical engineering and automation of Shanghai University, said: various terminals with environmental awareness, computing mode based on ubiquitous technology, mobile communication, etc. are constantly integrated into all links of industrial production. 2. Speed double closed-loop control can greatly improve manufacturing efficiency, improve product quality, reduce product costs and resource consumption, and promote traditional industry to a new stage of intelligent industry

for example, in the environmental protection industry, the integration of IOT and environmental protection equipment can realize the real-time monitoring of various pollution sources generated in the process of industrial production and key indicators in all links of pollution control. Installing wireless sensor equipment at the sewage outlets of some key enterprises can monitor the sewage data of enterprises in real time, and close the sewage outlets remotely to prevent sudden environmental pollution accidents. It is understood that at present, telecom operators have begun to promote real-time monitoring solutions for pollution control based on IOT. At the same time, the involvement of IOT has become a general trend in the supply chain management of manufacturing industry, the process optimization of production process, the monitoring management of product equipment and the management of industrial safety production

wireless integration technology deepens the development of IOT

throughout the development process of measurement and control system networking, from instrument electrical, fieldbus, industrial Ethernet to wireless network, we can notice that at present, wireless integration technology and wired wireless heterogeneity have become the development trend of measurement and control networking, which also promotes the deepening development of IOT in the industrial field on the one hand. Wireless communication technology can provide high broadband wireless data link and flexible network topology for the communication between various intelligent field devices, mobile robots and various automation devices in the factory environment. At present, wireless communication technology has developed from the initial supplement of wired technology to the coexistence of wireless and wired technology, and will eventually develop to the realization of perceptual network and the realization of the IOT world in the industrial environment

President Fei emphasized that at present, the hot technologies and key issues of wireless integration technology focus on reliability, compatibility, real-time, security and energy consumption. On the interconnection of industrial wireless measurement and control network and wired measurement and control network, the compatibility needs to focus on how to realize the wireless/wired protocol conversion, how to design the communication interface and how to operate the nodes (field devices) in the wireless measurement and control network; The energy consumption problem of wireless network access technology square aluminum tensile testing machine can reduce module energy consumption by adopting multiple working modes, increasing sleep time, reducing communication flow, selecting modulation mechanism and protocol design. In addition, there is also room for reducing consumption in energy mining, such as solar energy can reduce the emission power, wind energy can choose a shorter communication distance, and so on

in addition, the key problems of wireless integration into heterogeneous networks include forwarding delay, bandwidth difference, message forwarding type selection and security problems. President Fei introduced several strategies to solve these problems, he said: we can solve heterogeneity in the monitoring layer by using OPC technology; The protocol conversion and forwarding of the data link layer can also be carried out through the bridge, the user applications and device information between different field devices can be converted through the switch, and the wireless and wired networks can be connected through the repeater, which solves the problem of heterogeneity in the field device layer

facing the pressure of standards and market, wireless technology needs to go a long way, and the rise of IOT brings new development opportunities for wireless technology facing bottlenecks

IOT expands the development space of industrial wireless network

the 17th National Congress put forward the basic policy of developing a modern industrial system, vigorously promoting the integration of informatization and industrialization, promoting the transformation of industry from big to strong, revitalizing the equipment manufacturing industry, and eliminating backward production capacity. Industrialization drives informatization, and informatization promotes industrialization has also become the established policy of China's industrial development. Tu Xuan, deputy director of the Institute of intelligent instruments and systems of Shanghai Institute of industrial automation instrumentation, believes that at present, we should make full use of the characteristics of wireless sensor network WSN to carry out scientific research and development for the effective implementation of energy conservation, consumption reduction and emission reduction, which has also received great attention from the automation industry

President Fei also pointed out that M2M technology, which is the key support of the Eleventh Five Year Plan for the development of information industry science and technology and the medium and long term plan outline for 2020, has also become a hot spot. The wireless communication between machines has brought new solutions to the informatization of manufacturing industry

however, it can not be ignored that IOT covers a wide range of areas, and the standardization work is also scattered in different standards organizations, with different emphasis. There is overlap between them. The international standards organizations involved mainly include iso/iec, IEEE, IETF, etc. At present, the China IOT standards joint working group has been established in Beijing, which will greatly promote the research of IOT technology and the formulation of standards. At the same time, it will also become the wind vane of the industrial wireless network market. While providing development space for the industrial wireless network market, it also opens a new development direction for it
