Internet of Things entity interoperation method based on state model

Abstract

The invention discloses an Internet of Things entity interoperation method based on a state model. A state model is established for an Internet of Things entity; the abstraction of the Internet of Things entity is realized; as long as the Internet of Things entity has a similar behavior pattern, when the Internet of Things entity message is analyzed, a similar state model is established for the Internet of Things entity message, so that specific differences among different manufacturer devices are shielded, interoperability among different Internet of Things terminal devices is realized, semantic information in the Internet of Things entity message is analyzed based on the state model defined by a user, and the application range of semantic analysis in the Internet of Things is expanded.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a method for interoperating entities of the Internet of Things based on a state model. Background technique [0002] The Internet of Things is an information carrier such as the Internet and traditional telecommunication networks, and it is a network that enables all ordinary objects that can perform independent functions to realize interconnection. The Internet of Things connects all items to the Internet through radio frequency identification and other information sensing devices to realize intelligent identification and management. [0003] The existing technology mainly adopts the method based on semantic understanding to realize the interoperability of the terminal equipment of the Internet of Things, and obtains each entity of the Internet of Things application and the naming of each entity in the Internet according to the internal and external knowledge ba...

AI Technical Summary

Problems solved by technology

[0004] The existing technology mainly has the following deficiencies: 1. Due to the diversity of IoT devices, it is difficult for the existing technology to guarantee the compatibility between different IoT terminals. The interface and data specifications are agreed, and the messages sent and received by the two devices cannot be understood by the other party, so they cannot interoperate; 2. The existing technology can only follow the fixed semantic analysis logic and compare the fixed goals. Parsing semantics, semantic parsing methods are difficult and have low accuracy, which greatly limits the scope of application of existing technologies in IoT entities
