Application of Nuclear Power Engineering Material Management Based on QR Code + RFID Technology

The traditional engineering material management mainly relies on manual management, with poor transparency; or simple computer stand-alone management, lacking real-time tracking management. With the continuous development of enterprise scale, the traditional manual data collection method has been difficult to meet the rapid and accurate requirements of warehouse management, which has seriously affected the operation efficiency of engineering construction. With the continuous popularization of QR code and RFID technology, it is increasingly used in production, logistics and other industries, and its application in infrastructure industry is also gradually promoted. Through the use of Emei QR code and RFID electronic tags as a logistics and supply chain management process The information carrier of the articles in the article uses RFID readers and handheld data collectors as the information collection equipment to realize the rapid, automatic, effective and batch collection of information, the automatic management of information collection, the realization of human resources, equipment utilization, logistics and Effective management of supply chain management achieves the goal of optimizing processes and improving efficiency.

During the implementation of material management and e-commerce activities, all forms rely on their field information and coding information, add a QR code, set their tracking ID, and each time the information field is loaded, the information brought out by the QR code That is, it is loaded once, from starting production, leaving the factory, to installing into the main project, to ensure the traceability of materials.

The application of two-dimensional code + RFID technology is based on the enterprise ERP management system, e-commerce system, Internet of Things embedded system and handheld terminal operating system (APP). The system integrates the internal headquarters, sub (branch) companies, project department managers, operators , Suppliers, experts, and supervisors are linked into a complete supply chain, logistics, information flow, capital flow, etc. are integrated into one, and external resources and internal resources are coexisting and complementary.

These systems interact with each other to realize the labeling of two-dimensional codes + RFID tags of materials, from supplier management, demand planning, procurement planning, procurement management, acceptance, quality, storage, storage, inventory, transfer, and payment to payment In the supply chain management of the company, data is collected quickly and accurately, entered and transferred many times at a time, the business is open, the process is controlled, the whole process is on file, and the permanent traceability, the operation is safe, efficient, stable, and the information is shared and intelligently integrated.

The demonstration project of the application of two-dimensional code + RFID technology is set in a nuclear power engineering project, with a planned capacity of 6 million-kilowatt nuclear power units. Currently in the preliminary preparation stage of FCD, as the construction contractor of the nuclear island project, the existing material storage is about 3,500 square meters, including material yard, chemical warehouse, welding material warehouse, material greenhouse, etc.

In practical use, for materials that are not easy to damage the entire batch and a large number of materials, you can choose a low-cost QR code label; for materials that have a large value and long maintenance period, you can choose a higher-cost RFID label; for tight stacking RFID tags can be selected for components that are placed and not easily accessible for reading tags. For materials packed in bundles, such as steel bars, there is a nameplate on each side of each steel bar at the factory. You can paste the QR code on the nameplate, or bind the PVC material label with the QR code on each batch of steel bars; For For materials packed in bundles but without nameplates, such as steel belts, wire ropes, steel pipes, etc., PVC labels with a two-dimensional code can be tied to each bundle; for small items and a large number of materials, such as bolts, pipe fittings, Welding materials, etc., you can paste the two-dimensional code on the packaging box of each product; for flat and heavy products such as steel plates, special doors, plywood, etc., paste the two-dimensional code and RFID tag on the surface of the product. For bagged products, such as grout, special mortar, cement, etc., stick a QR code label on the packaging bag; for barreled products, such as paint, paint, etc., stick the QR code label on the packaging barrel.

The application of Emei QR Code + RFID technology will further deepen the service functions of materials, equipment, leasing, and labor subcontracting, combined with the use of financial services in the supply chain, and give full play to the characteristics of openness, collaboration, connection and sharing to realize the supply chain ecology Operation. Technically, through the Internet, QR code + RFID, sensors, controllers to realize the collection, transmission, processing, and execution of data such as materials, personnel, equipment, and status; on the business model, the design, production, and procurement of engineering projects , Construction, operation and maintenance, and other aspects of the entire life cycle value chain to innovate to improve resource allocation capabilities and efficiency.
