Internet of Things cloud access method and system based on Web Service

Abstract

The invention relates to an Internet of Things cloud access method and system based on Web Service. The method comprises the following steps of: 1, sending registration request information to a cloud receiving end through an Internet of Things emitting client; 2, feeding digital certificate information back to the Internet of Things emitting client by the cloud receiving end after receiving the registration request information; 3, acquiring a service resource identifier of the cloud receiving end through the Internet of Things emitting client; and 4, bidirectionally sending data information to the cloud receiving end at fixed period by the Internet of Things emitting client according to the service resource identifier and the digital certificate information. According to the Internet of Things cloud access method and system based on the Web Service, both the generality and the flexibility are combined, thus the problem of the conventional cloud access system can be solved well, the access equipment of various types can be compatible, and the data can be safely and reliably transmitted to a cloud center through the Internet of Things emitting client; an HTTP / HTTPS (Hyper Text Transport Protocol / Hypertext Transfer Protocol Secure) protocol is adopted, therefore, the possibility of error interception is avoided; and with the adoption of a self-defined JSON (JavaScript Object Notation) message format providing envelope mechanism, the industrial data models of various types are supported.

Description

technical field [0001] The present invention relates to a method for data transmission between the Internet of Things and the cloud, in particular to a method and system for accessing the Internet of Things cloud based on Web Service. Background technique [0002] Under the historical background that the whole society is gradually entering the era of the Internet of Things, ordinary people have become accustomed to connecting their devices or sensors to the cloud through the network, storing, processing and analyzing the uploaded data, as well as accessing personal devices. Many enterprises have also begun to install IoT terminal devices (mainly monitoring devices) in their factories, construction sites or office areas, and upload the data collected by these devices to private or public clouds. After the data is processed and analyzed, operations such as remote upgrade and remote control can be performed on the corresponding equipment. [0003] Internet of Things technology...

AI Technical Summary

Problems solved by technology

The message format provided by the existing cloud access system is not flexible enough to support industrial protocols, and there is no unified message format to be compatible with various protocols

Due to the lack of flexibility, the cloud center has great difficulty in verifying, parsing and processing the received data
