A method and device for accessing an Internet of Things device

Abstract

The invention discloses an Internet of Things device access method and device. The access method includes: receiving an instruction issued by an upper-layer business system, searching for the first device protocol associated with the first device model to encode the instruction, and searching for the first device protocol under the device domain. The adapter instance corresponding to the adapter model sends a downlink message, and the adapter instance sends the encoded instruction parameter information to the first IoT device or the third-party platform. The access method also includes: the adapter instance receives the device data uploaded by the first IoT device or pushed by the third-party platform, uploads the uplink message, searches for the uplink service processing module for data processing, and searches for the first device protocol associated with the first device model to perform Data decoding, and push the decoded data to the upper business system. This application solves the differences in device protocol encoding and decoding and device access methods by designing device models and adapter models, and flexibly supports unified operation and management of devices with arbitrary device protocols and access methods.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, and more specifically, to a method and device for accessing an Internet of Things device. Background technique [0002] In the process of building a smart city, the Internet of Things plays an important role. Installing Internet of Things devices on urban infrastructure such as manhole covers, geomagnetism, and street lights, so that they have "network identities" for intelligent identification and management, is an effective means of intelligent urban operation and management. However, the huge amount of urban infrastructure makes the effective access of massive IoT devices an urgent problem to be solved. [0003] IoT device access needs to consider the differences in device protocol codecs and device access methods. [0004] Device protocol encoding and decoding refers to the conversion between human understandable character data and corresponding byte data. Interactio...

AI Technical Summary

Problems solved by technology

However, different device protocols have different definitions, and the uploaded data defined by some protocols does not clearly distinguish between the protocol and the protocol version identifier, and the judgment conditions cannot be accurately matched to a specific protocol by setting the protocol format

Therefore, the data uploaded by the device cannot be uniformly distributed

[0009] (2) The existing device access method does not comprehensively consider the situation where the third-party platform method and the direct connection method are used to access the device
