The hottest industry to rediscover the Internet of

Re recognize the IOT industry

in 2009, the European intelligent system integration technology platform organization (EPoSS) gave a clear definition to IOT. IOT is a network that connects any object with the Internet according to the agreed agreement through radio frequency identification, infrared sensors, global positioning system, laser scanners and other information sensing devices, and carries out information exchange and communication, so as to realize intelligent identification, positioning, tracking, monitoring and management. This definition is most commonly cited. In the 2010 national government work report, China also adopted the definition of EPoSS, which believes that IOT is a network that connects any object with the Internet through information sensing equipment according to the agreed agreement, for information exchange and communication, so as to realize intelligent identification, positioning, monitoring and management. This definition is basically correct, but not comprehensive enough. The definition of EPoSS has the following problems: the definition does not limit the objects of perception and recognition, and the understanding of transmission network and bearer is limited to interconnection, which is not comprehensive enough, and the expression of the role of relevant protocols can be further improved

based on the above understanding, we believe that IOT is an application based on specific objects and meeting specific needs. The sense, knowledge and control of IOT on the physical world can only be oriented to specific and specific objects. Therefore, on the basis of EPoSS' definition of IOT, we further optimize the definition of IOT: IOT is to connect the items that need to be connected with the network through radio frequency identification, infrared sensors, global positioning system, laser scanners and other information sensing equipment, based on the actual management and application needs of social and economic fields, according to the agreed relevant agreements, for information exchange and communication, so as to realize intelligent identification, positioning, tracking A network of monitoring and management

in fact, there is no independent IOT. IOT is not an independent network, and no one can independently build an open and global IOT. Instead, regional, industrial and domain application networks can effectively cooperate and link through public or private networks to form an integrated IOT. Unlike interconnection, interconnection can build basic networks, then realize interconnection and expand applications. IOT is not simply to realize the connection between things. It is completely application-oriented, including industry applications, public domain applications, and family applications. Therefore, IOT is more regional, industrial and territorial

the application of IOT is based on specific objects, and there is no so-called perception of any object. The perception of IOT must be based on specific objects, and specific objects that need to be perceived are perceived. At present, some experts deliberately exaggerate the influence of IOT and IOT industry, and artificially expand the perception object of IOT to any object. In the field of IOT, only the actual management and application needs in the economic and social fields can be perceived, identified and connected by IOT. IOT is based on the actual management and application needs of the economy and society. Only things that need to be perceived can be perceived and controlled

analysis on the architecture of IOT

at present, the popular and typical IOT architecture in the industry is the three-tier architecture of sensing layer, transmission layer and application layer proposed by ITU. Some experts also wrote an article to divide IOT into three-tier architecture of equipment, connection and management. The three-tier structure thus distinguished has the problems of unclear architecture and unclear functional level. The dimensions and granularity of the three levels are inconsistent. Equipment is a product, Connection and management is a functional expression. As we all know, various devices are deployed in different functional layers. The underlying perception layer has devices, the transmission layer has devices, and the processing layer also has devices, and the connections are also distributed in various functional layers. That is, the management functions are also scattered at different levels of BYD. Therefore, the three-tier structure of device, connection and management is also unreasonable

a reasonable architecture should be an application-based, highly abstract functional level, which includes the perception layer, the transport layer and the processing layer. The perception layer is mainly responsible for the identification of objects and the collection of information. The transmission layer is responsible for the network access of various devices and the transmission of information. The processing layer completes the analysis, processing and decision-making of information, as well as the realization or completion of specific intelligent application and service tasks, so as to realize the recognition and perception between objects and people/objects, and play an intelligent role

perception layer: as the core layer of IOT, this layer is mainly used for the intelligent collection of item identification and information. It is composed of basic sensing devices and the network composed of sensors

transmission layer: the transmission layer mainly completes the functions of access and transmission. It is a data path for information exchange and transmission, including access and transmission. Transmission consists of public and private, and typical transmission networks include telecommunications, radio and television, interconnection, power communication, and private

processing layer: the processing layer is composed of business support platform (middleware platform), network management platform (such as M2M management platform) and information processing platform. Generally, there are three kinds of hardness commonly used: Brinell, Rockwell and Vickers hardness -- associate professor, doctoral tutor, information security platform, service support platform, etc., to complete the functions of collaboration, management, calculation, storage, analysis, mining, and providing services for Industry and public users, Typical technologies include middleware technology, virtual technology, high trust technology, cloud computing service mode, SOA system architecture method and other advanced technologies and service modes can be widely adopted

although the application characteristics of IOT in various fields of economy and society are very different as soon as possible, its basic architecture includes three levels: perception, transmission and processing, and various application subsystems are built based on the three-tier basic architecture

IOT industrial chain analysis

the industrial chain of IOT is very complete. From components to equipment, from software products to information services, each functional layer of IOT includes hardware products, hardware equipment to software products, system solutions, and operation and maintenance services of industry systems. We believe that the relatively complete IOT industrial chain mainly includes six links: perception and control device providers, perception layer end device providers, network providers, interconnection, radio and television, power communications, software and system solution providers, system integrators, operations and service providers

we should pay attention to the core industrial chain of IOT, that is, we should focus on industries directly related to the perception layer and the processing layer. We believe that the IOT transport layer belongs to a mature communication network with independent operation services, mature technology, mature application and relatively mature business model. It belongs to the network support service system of IOT and should not belong to the content of the core industrial chain of IOT. Of course, if the communication network operators, based on their own transmission network advantages, extend the services of the upper and lower perception layers and processing layers to provide the operation and maintenance services of the application system, this matter is no longer the traditional network transmission provider, but the industry-specific operation and maintenance services of IOT, which belongs to the operation and maintenance service provider

in IOT applications, there is no need for data transmission and data processing without the need for perception control. The perception layer is at the core and key position of the IOT industrial chain. The core of the perception layer is the provider of perception devices, the provider of end equipment of the perception layer and the software developer

the bottom layer of IOT realizes the sense. In order to realize the knowledge of items, and then realize the control of items, the intelligent processing of the processing layer plays an essential role. The software developers, system integrators and operation service providers of the processing layer play an important role in the IOT industrial chain. After an application system is completed, the continuous application and economic value come from the services of the processing layer

face up to the severe challenges faced by the development of China's IOT industry

at present, the development of China's IOT industry is facing economic, technological and security challenges. Specifically, the core technology needs to be broken through, and the standard system is not perfect; The cost remains high, and the business model needs to be explored; Information security is a bottleneck, and industrial security is facing a test; IOT industry involves not only information security, but also industrial security; As well as the disconnection between application and industry, it is difficult for application and industry to interact

to develop IOT in China, we should accurately grasp the development trend of IOT industry at home and abroad, seize the strategic opportunities of IOT industry development, take promoting the development of electronic information industry as the starting point, promote the integration of industrialization and industrialization as the foothold, take national security and social security as the fundamental point, adhere to the principles of planning first, technological breakthrough, application guidance and industrial follow-up, and strive to formulate a good industrial development plan and optimize the industrial layout of IOT in China; Strive to encourage technological innovation and overcome core technologies with independent property rights; Focus on guiding the application of IOT to drive industrial development; Focus on formulating industrial standards and standardizing industrial development; Focus on innovating business models and building a perfect industrial chain
