Big data transmission and persistence method and system for industrial intelligent internet of things

Abstract

The invention provides a big data transmission and persistence method and system for an industrial intelligent internet of things. The method comprises the following steps: an equipment data uploadingsecurity verification step: registering a user and encrypting uploaded data; a data transmission route distribution step: publishing the uploaded data and performing route distribution; a data analysis and persistence step: analyzing the uploaded data and carrying out data persistence operation. According to the metod disclosed in the invention, by adopting the modes of data security center registration and data connection encryption, the security problem of subdividing to transmission equipment and time granularity is solved; by adopting a weighted polling routing distribution rule, the problems of non-uniform load and data response delay in a data transmission and forwarding process are solved; by adopting a mode of combining real-time persistence and offline persistence, the problems that data persistence is difficult to align and data links are not unified are solved; configuration is loaded in a dynamic configuration center mode, and the problems that a traditional data transmission mode is inflexible in configuration and cumbersome in changed message processing logic are solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for big data transmission and persistence of the industrial intelligent manufacturing Internet of Things. Background technique [0002] In the traditional file transfer method based on the mqtt protocol, the transfer security depends on the mqtt proxy verification. This patent provides a way to register and issue a time-limited certificate through the data center, and encrypt the connection during the transfer process to ensure the transfer security; in addition Existing data transmission methods do not support high-speed storage persistence and [0003] The resource capacity of the transmission link is dynamically expanded. The routing distribution strategy adopted in this patent supports the dynamic expansion of the transmission node under the premise of ensuring the throughput and delay, and persists the transmission data in a highly fault-tolerant manner...

AI Technical Summary

Problems solved by technology

[0006] In the above scheme, the file transfer method based on the MQTT protocol does not realize clustered data distribution and routing, and the data throughput and low-latency transmission of data cannot be satisfied, while the method of secure data transmission based on MQTT does not realize the security verification based on the data center. Once the data is intercepted in the middle, there is a risk of encryption leakage and malicious insertion of dirty data
