Intelligent manufacturing is the future development direction of manufacturing industry. There are still some problems lurk in the traditional mode of production, such as “information island” and “network security”, which result in low productivity but high-cost production, and information leakage. With application of the new generation information technology in manufacturing field is expanded, the deep integration of information technology and manufacturing industry promotes the development of production towards intellectualization, networking, and service. Single mode of production is gradually replaced by the way of large-scale collaborative production, so the traditional industrial internet of things (IoT) and manufacturing architecture are not suitable for the needs of actual production any more. For instance, the great challenges of compatibility and coordination of interface protocols, huge data, cost, and safety. In order to solve these problems, a new model of industrial IoT with security mechanism used in intelligent workshop is proposed. Firstly, this article analyzes the current situation of manufacturing industry and information technology, a secure transmission model of industrial IoT was designed based on the new generation information technology. Secondly, combined with the structure of the IoT and the real production demands, a six-tier industrial IoT architecture based on the new generation information technology is proposed. Finally, the three dimensions of the intelligent manufacturing model are expanded according to the architecture of the IoT. Not only a six-tier intelligent manufacturing system framework based on the new generation of information technology is obtained, but also the network security mechanism is introduced. On one hand, it realizes the coordinated operation of industrial chain, supply chain, and value chain of production process, on the other hand, it also improves the networking, intellectualization, and service level of industrial production. What is more the system can also provide the reference model for the various application of IoT.

具有安全机制的工业物联网新模式——在柴油机复杂车间的应用

智能制造是未来制造业的发展方向。传统生产方式还存在“信息孤岛”、“网络安全”等问题，导致生产效率低、生产成本高、信息泄露等问题。随着新一代信息技术在制造领域的应用不断扩大，信息技术与制造业的深度融合，推动生产向智能化、网络化、服务化方向发展。单一的生产方式逐渐被大规模协同生产的方式所取代，传统的工业物联网（IoT）和制造架构已不再适合实际生产的需要。例如，接口协议的兼容性和协调性、海量数据、成本和安全性的巨大挑战。为了解决这些问题，提出了一种用于智能车间的具有安全机制的工业物联网新模式。本文首先分析了制造业和信息技术的现状，设计了一种基于新一代信息技术的工业物联网安全传输模型。其次，结合物联网的结构和实际生产需求，提出了基于新一代信息技术的六层工业物联网架构。最后，根据物联网的架构，扩展了智能制造模型的三个维度。不仅获得了基于新一代信息技术的六层智能制造系统框架，还引入了网络安全机制。一方面实现了产业链、供应链、生产过程价值链的协同运作，另一方面也提高了工业生产的网络化、智能化、服务化水平。更重要的是，该系统还可以为物联网的各种应用提供参考模型。
