In this paper, we propose the reefer container monitoring system that not only monitors internal temperature, humidity of reefer container but also tracks the real-time location using GPS. It consists of a tag of information of situation using 433MHz RF transmitter(communication), GPS to track the real-time location and a device using WCDMA/GSM communication to transmit information to the server. We tested by applying the proposed system in reefer containers with yellow melons, melons transported from Korea to Singapore to track the location and check the temperature and the humidity. The result of this test is that there is a temperature difference around 1.7 degree depending on the position of inside of container and maintains the humidity stably about 97%. If we apply this proposed system to agricultural marketing, it is possible to get the time that fruits start to decay and minimize the loss of fruits by decaying during shipping.

지금까지의 컨테이너 터미널은 항만 하역작업에 주안점을 두고 운영되어 왔다. 그리하여 크레인 기술 향상, 장치장의 현대화 등 많은 노력을 해왔으나 21세기가 시작된 지금은 컨테이너 터미널 내부에 각각 이루어지던 작업이 통합되어진 형태로의 운영이 필요한 시점에 이르게 되었다. 국내에서 건설하려는 컨테이너 터미널은 지금까지와는 다른 형태로 건설되어야 한다. 현재 컨테이너 터미널 운영 시스템 터미널 내부에서 발생하는 전체를 총괄하지는 못한다. 크레인 모니터링, 게이트모니터링, 작업 상황 등이 모두 다르게 되어 있어서 하역작업에 관한 내용만을 모니터링하는 수준이다. 본 논문에서 서술하고자 하는 통합 모니터링은 컨테이너 터미널 내에서 관제실에서 크레인 운전 정보, 작업 지시, 상황 보고, 게이트 모니터링, 사고 예방, 사고 발생시의 경보 등을 모두 하나로 묶는 문제 파악에서 부터 해결 방안 제시 등, 첨단화된 지능을 갖춘 컨테이너 터미널을 구현하는데 필요로 하는 내용들을 서술하여 그 방법을 제시 하고자 한다.

The recent trend of logistics demands for improved monitoring system of the inside of containers including current temperature and other environmental conditions. This paper presents an information processing technique with fuzzy logic that recognizes the current situations inside the target container and can be implemented on intelligent container systems. The ZigBee modules are used to collect information such as temperature, humidity, and shock inside the container in ubiquitous environment. The information processing system using fuzzy logic and the InTouch, one of SCADA(Supervisory Control and Data Acquisition) systems, is implemented to monitor the inside of the container and predict the emergency state.

This paper proposes the ITMS(Intelligent Transport Monitoring System) which manages the route and state of freight by using the Meteorological Office, the Transportation Management Center, GPS and Sensors, etc. The ITMS consists of the CIMS(Container Inner Monitoring System) transmitting the inner temperature and humidity of a container, the TMM(Transport Management Module) computing an estimated time of arrival with Freight Vehicle location information and transmits the result to the CIMS, the FMM(Freight Management Module) checking and managing the freight freshness by using the temperature and humidity of the collected containers, and the SMM(Stevedoring Management Module) selecting the container loading and unloading places with the information transmitted from the CIMS, the TMM, and the FMM and attaching the freight formation to containers using an RFID label. The ITMS not only checks the freight condition at intervals but also acquires and manages the freight information with RFID labels rapidly and accurately.

스마트 컨테이너 제어를 위해서는 컨테이너 내부에 센서가 필요하나, 센서의 개수가 증가하면 비용 및 시스템 부하가 증가한다. 본 연구에서는 CFD(Computational Fluid Dynamics)를 이용하여 얻은 컨테이너 내부 온도 데이터와 센서 위치 최적화 알고리즘을 이용하여 컨테이너 내부 모니터링을 위한 최적의 센서 위치 결정 방법론을 제시한다. CFD 상용 SW로 컨테이너 내·외부 상황을 가정하여 내부 온도 데이터를 추출하고, 이를 바탕으로 내부 상태를 대표하는 공간들을 구분한다. 컨테이너 내벽에 부착된 센서가 탐지할 수 있는 능력을 탐지 거리 및 각도의 수식들로 나타내어 각 수식을 조합하여 센서의 탐지 능력을 수치화하고, 이 수치에 따라 균등하게 분포된 센서 위치 후보군 중, 선별된 공간을 탐지하는 센서 위치를 최적화하여 효율적인 컨테이너 제어를 위한 여건을 마련한다.

In this paper, we designed and built a system that is site manager can be monitored remotely to the growth of the fishery environment. To this end, modular distribution system and environmental monitoring of live fishery products. Simulation results, were building a purification system and the oxygen supply to the fishery living inside the container was to build a system that can be monitored in real time. As a result, it was able to raise the necessary environment for the storage and distribution of fisheries products. We constructed a monitoring system with database and communication environment and created the optimal environment suitable for growth with sensor. As a result, it was possible to monitor the environment for the storage and distribution of fishery products and to build a suitable fishery products management system.

The contents of reef container face a risk of being damaged if the interior temperature and certain maintenance conditions for the shipments cannot be met. Currently, the temperature and other conditions within a reefer container is checked manually and periodically by someone in charge of it. Since it means that there is no real-time checking of the conditions, if something goes wrong, there is no immediate means of correcting the problem. This paper introduces reefer container monitoring system, that checks interior temperature of container on real-time by sensor nodes attaching reefer container using wireless sensor network. It senses the temperature, amount of light, motion and the change in speed of the objects that distributes sensors throughout the desired places and sends the data wirelessly to anyone interested. Because the prosed technique can check the temperature and other conditions within a reefer container on real-time basis, it enables efficient and effective maintenance of temperature and other conditions

X-ray of up to 9MeV are used for container inspection. X-ray intensity must be maintained stably regardless of changes in time. If dose is not constant, it may affect the image quality, and as a result, may affect the inspection of abnormal cargo. Therefore, to acquire high-quality images, continuous dose monitoring is required. In this study, the ion-chamber based device was developed for monitoring the dose change in high-energy x-ray. And to estimate the performance of signal-processing device change according to the environmental change, the output changing due to the change of temperature and humidity was observed. In addition, verification of the device was performed by measuring the output change. As a result of the measurement, there was no significant difference in performance due to changes in temperature and humidity, and the change in output according to the change in exposure was linear. Therefore, it was found that the developed device is suitable for the dose monitoring of high-energy x-ray.
