Abstract: According to current status and regulatory requirements of quality management in wire and cable industry, taking the pilot work of wire and cable quality traceability system construction based on Ecode identification for internet of things as a case, the specific working ideas of wire and cable industry were elaborated on, which used item coding as the carrier, ontology identification of coding as the core, and gathered quality traceability information through big data technology to realize the quality traceability of products from production, sales to use. The overall framework system of wire and cable quality traceability was introduced, focusing on specific business processes of coding application, distribution, identification, and information services. Achievements of quality traceability system construction in enhancing regulatory capabilities, reducing counterfeiting and shoddy products, empowering digital transformation, and forming social governance forces were summarized and analyzed. The issues that should be further improved and paid attention to in quality traceability system were put forward, so as to enhance sustainability of quality traceability system construction and provid reference and inspiration for intelligent supervision in wire and cable industry.
