Self-adaptive access method and system for heterogeneous equipment of Internet of Things platform

Abstract

The invention belongs to the technical field of Internet of Things, and discloses a self-adaptive access method and system for heterogeneous equipment of an Internet of Things platform. The system comprises a protocol identification obtaining module which is used for obtaining the identification of an equipment access layer non-standard Internet of Things protocol in an overall architecture; and aheterogeneous protocol unification middleware which comprises a virtual device model layer, a model mapping layer and an application data model layer. According to the method, the Internet of Thingsplatform with application development as the center is constructed, existing software development companies and personnel are better utilized, and the flexibility, user experience and software qualityof constructing the Internet of Things application are improved. According to the invention, a stable virtual device data model mapping mechanism is developed for an application program, and a virtual device data model sharing co-construction method suitable for software developers is constructed.

Description

Technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a method and system for adaptive access of heterogeneous devices on an Internet of Things platform. Background technique [0002] At present, the Internet of Things market is huge, and it is estimated that the global Internet of Things market will reach US$1.9 trillion by 2020. And the IoT industry chain is lengthy, involving software and hardware development, embedded development, cloud product purchase, server construction and maintenance, and many other links. Among them, the development cycle and quality of IoT application software are the key to the success or failure of IoT projects. Therefore, shortening the development cycle of Internet of Things application software and improving the quality of Internet of Things software are problems to be solved urgently. [0003] Traditional Internet of Things application development is centered on equipment, and...

AI Technical Summary

Problems solved by technology

The heterogeneous protocol analysis gateway is a hardware entity, which does not meet the requirements of some scenarios. For example, the smart door lock scenario is not suitable for adding an additional hardware entity, and the heterogeneous protocol gateway is generally aimed at sensor network protocols, such as: Bluetooth, zigbee, etc., not for MQTT, CoAP and other application layer protocols

[0006] Through the above analysis, the existing problems and defects of the existing technology are: (1) There is a strong coupling between the existing technology for the application of the Internet of Things and the device, so that the user must purchase multiple sets of the Internet of Things platform and the Internet of Things when solving practical problems using the Internet of Things. Networking application developers or solution providers must also master the device access and development methods of different platforms or develop access modules by themselves, which lengthens the development cycle of IoT applications

[0007] (2) The data format standardization method dominated by the standard organization in the existing technology cannot meet the marketization needs of the Internet of Things market with a large variety of devices and emerging new Internet of Things devices

The difficulty is that the data format standard system of the Internet of Things protocol is imperfect and the number of standards is complicated. It is difficult for a single standard to adapt to the numerous Internet of Things devices in the Internet of Things industry.
