Development of Reefer Container Real-time Management System

Abstract

In spite of a recent trend of container ships becoming larger in size, the current circumstance is that managing reefer containers marine transportation is being mostly dependent upon manpower. Particularly, in the case of bad weather or nighttime, reefer containers are not being monitored due to lack of safety device. For the purpose of reducing such risk, IMO is recommending a system using PLC but the system is not being used. In addition, they are still relying on manpower for control and reliability of freight in transit is decreasing due to lack of information during marine transportation for every subject related to freight as well as shipper. Accordingly, the purpose of this paper is to propose a real-time reefer container management system to effectively control all reefer containers widely being used across the world.

A U-shaped Association between Body Mass Index and Psychological Distress on the Multiphasic Personality Inventory: Retrospective Cross-sectional Analysis of 19-year-old Men in Korea

“…Thus, the test is an objective personality test similar to the MMPI. The test-retest reliability and Cronbach's alpha of the MPI range from 0.61-0.83 and 0.58-0.80 for the scales, and the discrimination rate of the MPI is 80% ( 25 ).…”

Fresh Agricultural Product Export Environment Analysis Using IP-RFID-based Reefer Container Monitoring Equipment

“…Targeting the strawberry exported using the maritime transport method and the air transport method from Korea to Far Eastern Russia, this study monitored the export environment through the application of the IP-RFID-based reefer container monitoring system introduced in this study for strawberry cargo [12].…”

“…[9][10] Table 1 summarized the characteristics and limitations of current methods to monitor reefer containers. [11][12] This system consists of the IP-RFID Tag attached to the cargo inside the reefer container, which senses the temperature, humidity, and impact around the cargo, and transmits them to the outside using 433MHz RF communication system. Meanwhile, the Smart Point installed inside of the control unit box that collects the status information of the cargo transmitted from the multiple IP-RFID tags and after the collection, transmits the data again to the remote service platform on a real-time basis after adding the location information of the reefer container using GPS technology.…”
