최근에 시판 되고 있는 냉동·냉장 가전제품은 사물인터넷(IoT) 기능이 추가된 제품이 출시되고 있으나, IoT 기능에 대한 시험은 거의 없는 실정이다. 특히 기존의 시험체제에서는 IoT 기반의 냉동·냉장 가전제품에 대해 IoT 시험항목이 마련되어 있지 않아 제품을 제조하는 업체의 경우에는 결함이 발생하더라도 원인을 쉽게 찾기가 어려우며, 시험기관의 경우에도 IoT와 관련한 시험항목 선정 및 방법의 부재로 올바른 성능시험 수행에 제약이 있다. 본 논문에서는 가전기기 분야의 제품 중 IoT 기능이 포함된 냉동·냉장 제품의 성능시험 프로세스에서 제품 결함을 찾아내고 그 원인을 식별할 수 있는 시험항목 프레임워크를 설계하고, 이를 이용한 시험방법 및 관리방안을 제안한다. 제안하는 연구를 통해 제조사 및 시험기관은 IoT 기반의 냉동·냉장 제품의 올바른 성능시험이 가능하여, 제품의 완성도를 높이고 신뢰성을 확보할 수 있다.

Abstract ▼ AI-Helper

Recently, frozen and refrigerated appliances on the market are being released with additional IoT functions, but there are few tests on IoT functions. In particular, the existing test system does not have IoT test items for IoT-based frozen and refrigerated appliances, making it difficult for companies to find the cause even if defects occur, and test institutions are also restricted from selecting IoT-related test items and conducting correct performance tests. In this paper, we design a test item framework that can identify product defects and identify causes in the performance test process of frozen and refrigerated products with IoT functions among products in the home appliance field, and propose test methods and management measures using them. Through the proposed research, manufacturers and testing institutions can test the correct performance of IoT-based frozen and refrigerated products, thereby enhancing the completeness and securing reliability of the products.
