  • This study was conducted as a basic study for the selection of tags suitable for logistics management in the palletized unit-load unit and the development of various technologies to activate the palletized unit-load shipment of agricultural products through local APCs. Three types of passive RFID tags of UHF 900 MHz and one type of active RFID tag of 2.4 GHz band designed and manufactured through this study were used to analyze the receiving strength according to the tag's attachment location and distance of the palletized unit-load of agricultural products. In the passive RFID tag, there was a large difference in receiving strength by the tag's attachment location and a large amount of data loss depending on the distance within 30 m, whereas, in the active RFID tag, it was superior to the passive tags in terms of both receiving strength and data loss. Therefore, active tags are desirable from the perspective of multiple identification of warehouses with large spaces in relation to the application of RFID tags for palletized unit-loads of agricultural products, but the development of low-power technologies such as software wakeup power management as well as hardware to minimize battery power consumption is necessary.

  • 현재, 국내 랙크식 창고의 소화설비들은 연면적 및 층수만을 고려하는 평면적인 입장에서의 사양설계로 이루어지고 있다. 하지만 수직적인 구조를 갖는 랙크식 창고는 평면적인 소화설비뿐만 아니라 입면적인 측면도 함께 고려되어져야 하며, 상황에 따른 적절한 성능설계를 지향하기 위해서는 랙크 내 적재되는 물품의 화재하중 산정이 우선시되어야 한다. 이에 본 연구에서는 국내 현장조사 결과와 국외 적재물품 위험도등급 등을 함께 고려하여 구성된 표준 파렛트단위 적재물품(파렛트 +박스단위 적재물품 +비닐포장재)의 화재특성을 분석하였다. 그 결과로 화재하중 산정을 위한 열방출율 및 화재감지기 등의 소화설비를 위한 환경조건인 연기발생률을 도출하였다.

  • Is not used by consistency transport at transport of freight nothing but is using Pallet only by pedestal when work palletized unit load or materials handling when keep simplicity receptacle which fill raw material or product in factory in our country. Therefore, pallet that is most important function of Pallet is not empled circulation to end consumer from manufacturing plant which is circulation process whole path being done and factory. It is real condition stopping only in extremely determinate part process use of warehouse back. Additionally, it is possible to figure out the flow of all the materials loaded on the RFID pallet; product, material, raw material immediately, so that epoch-making management is possible and it contributes to the reduction of logistics cost because there are little loss or outflow of pallet. The materials flow is getting speedy and inventory is decreasing in the logistics process, and also bad inventory and loss problems are prevented. As a result, not only logistics cost of company but also national logistics cost is decreased. Thus it contributes to the strength of national competitiveness.
