technical field

The invention relates to the technical field of wireless communication, in particular to a physical entity model building block for an intelligent port, an intelligent port and an intelligent network.

Background technique

German Industry 4.0 originated from the Hannover Messe in 2011. The German industry put forward the idea to improve the German manufacturing level through the application of technologies such as the Internet of Things, and released "Securing the Future of German Manufacturing: About Implementation" in April 2013 Proposals for Industry 4.0 Strategies". The concept of Industry 4.0 is the fourth industrial revolution led by intelligent manufacturing. The strategy aims to transform the manufacturing industry into intelligence by making full use of the combination of information and communication technology and cyberspace virtual system. However, in terms of how to achieve intelligent transformation, they are all designed based on specific factory needs, and the norms are not universal enough to be common among different industries, and there is no concept and function realization of a smart port.

In 2014, China Electronics Technology Group proposed the concept of IoT port. IoT port refers to the ability to provide equipment access to the bottom and the ability to package and release object services to the top. As the middleware of the Internet of Things, it shields the construction of the Internet of Things application system. Heterogeneity of the underlying layer. For device accessors, they can use the object access capabilities provided by the port to access devices. For application development, they can use the object services provided by the port to develop complex object applications. At the same time, many basic IoT ports can be combined and connected into a more complex IoT port. Through the TNS general architecture, all objects connected to the port can be addressed and precisely controlled in the whole network. It can be seen that IoT Port does not emphasize intelligent processing and services, and its support for ordinary users and intelligent manufacturing is far from enough.

Smart cities and smart manufacturing urgently need a common service platform, so that smart cities and smart manufacturing can be realized on the basis of making full use of existing equipment and at a relatively low cost, especially to solve the lack of smart processing for general users Ability issue.

Therefore, the current use of cyber physical systems (CPS, Cyber Physical System). A cyber-physical system is a complex intelligent system, and the ability to perceive changes in the physical environment is an important attribute of it. As a new information acquisition and processing technology, sensor network is an important part of cyber-physical system. Cyber-physical systems are closely connected to the real world through sensor networks, and the advanced computing capabilities of cyberspace are effectively used in the real world, so that in the manufacturing process, all data related to design, development, and production will be collected and analyzed by sensors , forming an intelligent production system that can operate autonomously. Its essence is to realize "smart factory", "smart production" and "smart logistics" based on "cyber-physical system". The essence of "Internet +" is to use the Internet, big data, cloud computing, and the Internet of Things to combine with modern manufacturing to promote the healthy development of e-commerce, industrial Internet and Internet finance. Establish a highly flexible intelligent production model of personalized and digital products and services. These features are similar to Germany's Industry 4.0. Cyber-physical systems can realize the interaction between the physical world, the computing world, and the ternary world of human society.

For example, the air conditioner connected to the network, the user can turn on or off the air conditioner through the network, and the air conditioner connected to the power supply can cool, heat, dehumidify, ventilate and other functions. At this time, first describe the attribute name, type and value range of the relevant capability in the capability section. For example, the value range of the switch type is defined as Turn_value:=('on', 'off'), then the control statement to turn on the air conditioner is: Control(Resource_model_code, VR_code, IP_add, Turn := 'On').

The model relationship segment editing module 115 is used for encapsulating the service that physical entities obtain knowledge and intelligence through the network.

The model relationship segment is used to describe the growing knowledge of the object (including the knowledge of interaction with other physical entities), the intelligence obtained from the intelligent network service platform, autonomous intelligence, etc.

Referring to FIG. 5, FIG. 5 is a schematic structural diagram of an intelligent network provided by the present invention.

On the basis of providing the above-mentioned smart port, the present invention provides an intelligent network, including the above-mentioned smart port. The intelligent network in a narrow sense is based on the Internet and the Internet of Things, and its core components are the intelligent port and the intelligent network service platform, which are used to support the development and operation of cyber-physical systems. In a broad sense, the intelligent network is equal to intelligent port + intelligent network service platform + Internet + Internet of Things + CPS. Systems such as new smart cities, new smart homes, and smart manufacturing based on smart networks are so-called cyber-physical systems. A smart port can exist independently of the existing network, such as a separate smart home port, which can exist independently without access to the established Internet or Internet of Things.

The characteristic of the intelligent network is to support the sharing and intelligent interaction of physical entities.

The operation mechanism of the intelligent network is as follows: the physical entity of the cyber-physical system is registered and connected to a smart port, the smart port is responsible for direct or indirect interaction with the physical entity, and the smart port stores the virtual entity corresponding to the physical entity and the access network of the physical entity The physical entity information that the information indirectly interacts with may not be stored in the smart port. People, physical entities or smart ports in the intelligent network can call the standardized control statements of the capability segment according to the description of the intelligent application segment of the virtual entity, and obtain the real-time status and perception results of the physical entity. A registered physical entity can be connected to any smart port, and a physical entity in a cyber-physical system can be connected to different smart ports. People generally interact with physical entities or implement control behaviors indirectly through intelligent network service platforms or smart ports. However, intelligent interaction and control behaviors can occur directly between physical entities or through intelligent network service platforms and intelligent ports. This is the so-called deep integration of information systems and physical systems, that is, cyber-physical systems. Any physical entity connected to the intelligent network can become a CPS node with communication, intelligent computing and control capabilities. Any number of CPS nodes constitutes a CPS system. The CPS system can also be regarded as a CPS node, which is superimposed and interacts with each other to form an intelligent network or intelligent network space.

The basic capabilities of the entity are defined when building the virtual entity model; when accessing the smart port, the ability to customize the service platform for registered users is instantiated; after accessing the network, further capabilities are obtained through intelligent learning. Due to the sharing of physical entity capabilities of the intelligent network, in a broad sense, it can be considered that any capability of the intelligent network can be obtained after accessing the network.

There is a two-way solid line between the smart port and the Internet and the Internet of Things, indicating that they are closely connected. The core part of the intelligent service platform is generally deployed in the intelligent network operation management center, which can also be regarded as a special port or intelligent engine of the intelligent network. The intelligent service platform is connected with the existing network by two-way solid lines, indicating that the two are closely connected and mutually supportive.

The intelligent network service platform is connected with the dotted line of CPS, indicating that it is indirectly connected. CPS nodes have the capabilities of communication, intelligence and control. After registering and customizing intelligent services, the CPS system can run independently of the intelligent network service platform. For example, a single robot system can access the network to obtain services or provide services, or can independently run. CPS nodes generally need to exchange information with smart ports, which may be delayed, so the two are connected by wide arrows, indicating a strong association. The overlapping of two CPSs means that one physical entity can be part of multiple CPSs at the same time, which indicates that not only information is shared on the intelligent network, but also physical entities are shared. This lays the foundation for improving the utilization of resources, which is also an inevitable requirement for smart cities or smart manufacturing. The intersection of CPS and existing networks indicates that CPS can utilize the resources of existing networks or the Internet of Things.

For example, if a camera is installed in a room, it can be regarded as a simple cyber-physical system supported by an intelligent network service platform. If a stranger enters, it will automatically call the police, and take a photo and send it to the designated mobile phone, while familiar people will not call the police. Any camera registered to this intelligent service platform can have this function, as long as he provides relevant photos of acquaintances in advance, the number of acquaintances will be automatically increased in the future, which can reflect intelligence to a certain extent. The action of taking pictures and who to send them to can be designed or customized by the user under the support of the intelligent network service platform. User-customized processes can be provided as a service of the platform for other users to use or refer to. User-customized processes can be provided as a service of the platform for other users to use or refer to. User-customized processes can be provided as a service of the platform for other users to use or refer to. User-customized processes can be provided as a service of the platform for other users to use or refer to. In principle, users can obtain any service on the smart service platform under the premise of authorization, and these services are constantly increasing, and the intelligence is also increasing independently.

Compared with the Internet and the Internet of Things, the intelligent network has added a smart port and an intelligent network service platform, which can support the perception of the state of physical entities and share capabilities, forming an effective support environment for the operation of cyber-physical systems.

Above, the physical entity class model building block, smart port and smart network provided by the present invention have been introduced in detail, and the specific principles and implementation methods of the present invention have been set forth through the embodiments, and these descriptions are only used to help Understand the core idea of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can be made to the present invention, and these improvements and modifications also belong to the protection scope of the claims of the present invention.
