Method for accessing and managing massive Internet of Things devices

Abstract

The invention belongs to the technical field of Internet of Things, discloses a mass Internet of Things equipment access and management method, and designs a unified equipment abstract model. The equipment abstract model is used for describing the capability characteristics of the equipment, and the abstract model is used for describing the capability of the equipment and the provided service; and the equipment model is described in the forms of JSON and XML, and the model is uploaded to a cloud system and an equipment end after the equipment model is developed. And the capability characteristics of the equipment are equipment model identification attributes: equipment type, manufacturer, model, protocol type, service supported by the equipment, attribute and control command. According to the method, the steps are simple and clear, the massive heterogeneous equipment is subjected to standardization processing by designing the equipment unified description model, and a very good effect can be achieved. Compared with the existing Internet of Things access technology, the mass Internet of Things equipment access and management method provided by the invention fundamentally solves the problems of difficulty in Internet of Things equipment access, high cost, poor safety and difficulty in interaction.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a method for accessing and managing massive Internet of Things devices. Background technique [0002] At present, the Internet of Things has formed a distinct hierarchical architecture in the development process: perception layer, network layer, platform layer, and application layer. The core of the Internet of Things is data, and the source of data is a variety of sensor devices. Obtaining information about the physical world through sensing devices installed on the devices is an important means of digitizing information, thus forming the most cutting-edge Internet of Things The perception layer; the access layer is responsible for selecting the appropriate communication technology for the digital information received by the perception layer according to the needs of scenarios and costs, such as short-distance communication technologies represented by ...

AI Technical Summary

Problems solved by technology

[0005] (1) The devices produced by IoT device manufacturers have different communication protocols, communication processes, and interaction methods, resulting in high access costs, poor security, and difficult interactions for IoT devices

[0006] (2) Requirement changes in the development process of IoT applications require re-adaptation and coding operations, resulting in difficult maintenance and redundant codes;

[0007] (3) The existing technology lacks a unified model standard. Although the IoT platform manufacturers provide an SDK to facilitate developers to integrate the platform on the device side, they can only be integrated according to the platform standard, resulting in incompatibility between various systems and " The emergence of "information islands" is not conducive to users and developers to develop once and adapt to multiple places

The difficulty lies in the inability to analyze these heterogeneous data in a unified way. The types of data analyzed by the Internet of Things platform are limited, and it is difficult to realize massive data analysis.

[0010] (2) The problem of re-adaptation in response to changes in the development requirements of Internet of Things applications

The difficulty is that although various manufacturers provide SDKs to lower the threshold for device integration and networking, it also leads to a device that can only be connected to one IoT platform, making it difficult to share data. Networking presents a learning cost
