Abstract

There is a new evolution in technological advancement taking place called the Internet of Things (IoT). The IoT enables physical world objects in our surroundings to be connected to the Internet. For this idea to come to life, two architectures are required: the Sensing Entity in the environment which collects data and connects to the cloud and the Cloud Service that hosts the data. In particular, the combination of wireless sensor network for sensing and cloud computing for managing sensor data is becoming a popular intervention for the IoT era. The pharmaceutical cold chain requires controlled environmental conditions for the sensitive products in order for them to maintain their potency and fit for consumption. The monitoring of distribution process is the only assurance that a process has been successfully validated. The distribution process is so critical that anomaly at any point will result in the process being no longer valid. Taking the cold chain monitoring to IoT and using its benefits and power will result in better management and product handling in the cold chain. In this paper, Arduino based wireless sensor network for storage and logistics (land and sea) is presented and integrated with Xively cloud service to offer a real-time and innovative solution for pharmaceutical cold chain monitoring.

사물을 인터넷에 연결시키는 기술인 Internet of Things(IoT)는 새로운 연구분야가 되어 기술적으로 많은 발전이 이루어져왔다. 이러한 IoT 기술은 사물을 관찰하거나 다루는데 있어 쉽게 접근하도록 하여 네트워크 상에서 인터넷으로 데이터의 전달을 가능하게 한다. 이는 두가지의 인프라를 필요로 하는데 하나는 데이터를 수집하는 Sensing Entity이고 다른 하나는 데이터를 점유하는 Sensor Cloud이다. 여기서 무선 센서 네트워크는 사물로부터 측정되는 데이터를 인터넷에 연결시키는데 매우 중요한 역할을 하는데 간단한 컴퓨팅 디바이스나 Arduino, Raspberry Pi와 같은 임베디드시스템으로 구성될 수 있다. Sensor Cloud는 사물로부터 측정되어 나오는 데이터의 공유나 처리를 하도록 하는 클라우드 컴퓨팅으로 모니터링 혹은 컨트롤 시스템에 대한 플랫폼을 제공한다. 본 논문에서는 의약품의 저장 조건들을 모니터링 하는 Cold Chain을 제안한다. 제안된 Cold Chain은 생산에서 소비단계까지 이르는 이동이나 저장상태에 대한 여러 환경적 조건인 습도, 온도, 저장 장소 등을 모니터링 하는 시스템이다. 시스템은 두개의 부시스템으로 구성되는데 하나는 이동에 관련된 것을 다루고 다른 하나는 저장에 관련된 것을 다룬다. 이 두 개의 시스템은 보다 향상된 모니터링 방법을 제공하기 위해 Sensor Cloud 시스템으로 통합된다.
