Description

Smart Factory Data Collection System Using Blockchain Technology The present invention relates to a smart factory data collection system utilizing blockchain technology, and more specifically, to a technology that enhances data security and transparency of a smart factory by collecting process data from already established IoT nodes in a smart factory data collection system where a POP (Point Of Production) or MES (Manufacturing Execution System) is established, forming a blockchain, and distributing and storing it across each node. Smart factories are advanced production systems that lead the future of manufacturing. It can be described as a system that goes beyond simply automating machinery to intelligently connecting and optimizing all processes, from product planning to production and distribution, by utilizing Information and Communication Technology (ICT). Smart factories minimize human intervention and efficiently operate production processes through robots and automation systems. They utilize sensors, big data analysis, and artificial intelligence to collect and analyze production data in real time, automating predictive maintenance and quality control. Furthermore, they establish a flexible production system capable of rapidly responding to market changes, such as multi-product, small-batch production and customized manufacturing, while ensuring connectivity that optimizes the entire process by networking all devices and systems within the factory to exchange information in real time. Such smart factories have the advantages of maximizing productivity and reducing production costs through automation and optimization, improving product quality by predicting and resolving quality issues in advance through real-time data analysis, optimizing production plans, shortening delivery times by reducing unnecessary inventory, increasing energy efficiency by optimizing energy consumption, and contributing to environmental protection. Smart factories are composed of sensors that collect various data from the production site; IoT platforms that connect and analyze the collected data; big data analysis, which derives insights by analyzing vast amounts of data; artificial intelligence that performs functions such as prediction, learning, and optimization; cloud computing that provides a cloud environment for data storage, processing, and analysis; and robots that automate repetitive tasks and perform precise work; and are expected to emerge as a core technology that will change the paradigm of manufacturing and lead the era of the Fourth Industrial Revolution. While smart factories offer various advantages such as increased productivity and improved quality, they face challenges including high initial investment costs, the potential for system failures, security risks like production data leakage and system paralysis due to vulnerability to cyber attacks, and the difficulty of efficiently managing and analyzing vast amounts of data. Therefore, there is a problem requiring a robust security system to protect sensitive production data. As smart factories generate and utilize vast amounts of data to enhance productivity and quality, this data faces a high risk of exposure to cyber attacks, making data security a critical issue. Blockchain technology is opening up new possibilities by enhancing data security and transparency in smart factories. Blockchain's distributed ledger technology guarantees data integrity by making it impossible to alter data once it is recorded, thereby enabling the secure recording and management of all data generated during the production process (raw materials, parts, product information, etc.). Because blockchain stores data in a distributed manner among nodes without a central server, it can significantly reduce the risk of hacking or data leakage, and it offers the advantage of streamlining supply chain management by enabling real-time information sharing and collaboration through the blockchain network. Korean prior patent No. 102330347, 'Blockchain-based Smart Factory Operating System,' is a technology designed to achieve these advantages and presents a structure for installing a blockchain system in a smart factory. However, in the case of such technology, there is a technical problem in that installing blockchain infrastructure in existing smart factories poses an excessive burden in terms of cost and time to establishing blockchain-based nodes, networks, and authentication systems within an already installed environment. Korean prior patent application No. 10-2019-0172280, 'Blockchain Energy Management Platform in Smart Factory Environment,' also has the same technical problem as an invention that establishes a separate blockchain platform in a smart factory in this manner. Korean prior patent application No. 10-2019-0143866, 'Blockchain-linked smart factory production management system,' relates to a blockchain-linked smart factory MES (Manufacturing Execution System) that suppor
