A remote access and anti-tampering system for industrial field data in the industrial Internet of Things

Abstract

The invention discloses a remote access and anti-tampering system for industrial field data in the industrial internet of things, comprising a field device layer, a field data acquisition layer, a block data service layer, and a remote data application layer. The field data acquisition layer includes a first switch, the field device layer is connected to the first switch through OPC UA, the block data service layer includes a first server and a plurality of second servers, and the first switch is connected to the first switch. The server is connected, and the first server forms information interaction with multiple second servers, and multiple second servers realize data encryption acquisition and tamper-proof mechanism through blockchain technology, and the first server communicates with the corresponding second server through the Internet. Information interaction is realized, and the remote data application layer interacts with data in the second server. The invention has the advantages that: the invention improves the openness and interoperability of the system, can realize the remote access of the remote data application layer to the field device layer and prevent data from being tampered with.

Description

technical field [0001] The invention relates to the field of industrial site data acquisition, in particular to a remote access and tamper-proof system for industrial site data in the Industrial Internet of Things. Background technique [0002] The automation level of processing and assembly workshops in modern machine manufacturing is getting higher and higher, which requires fine digital management of the production process. Therefore, the modern production management system should have the basic functions of data collection, storage, statistics and analysis of the production process. Although a powerful and easy-to-maintain production data processing and management system can be quickly established by using the PC architecture, the .NET software development platform provided by MicroSoft, mature database technology and network communication technology; Access to process data comes into play. [0003] For the development of the manufacturing industry, an industrial Inter...
