Abstract

A sensor network which is composed of a large number of sensors that perform various sensing is applied in a variety of fields. The sensor networks can be widely used for various application area like as home automation, fire detection and security area. Development of new sensor to have appropriate functions and deployment of networks for suitable application are served actively. In this paper, we design and implement a system that monitors various factory facilities by deploying sensor network at a working place which threatens the worker's safety. A sensor node reports its sensing data like as temperature and humidity to monitor facilities to a sink node. And the server which is connect to the sink node gathers and provides information by user interface. In addition, digital data which are generated at a work place can be transferred via the sensor network to increase the efficiency of works. The proposed sensor network provides the convenience of working, since it is deployed at a garbage collection company to monitor a temperature and humidity of garbage and to transmit data about the weight of trucks which enters the company.

주변 환경을 감시하도록 구축된 센서 네트워크는 다양한 감지 작업을 수행하는 센서들로 구성되어 있으며 다양한 분야에서 적용되고 있다. 센서 네트워크는 가정 자동화, 화재감지 및 보안 분야 등기 다양한 응용분야에서 광범위하게 사용되고 있으며, 적절한 기능을 가지는 센서의 개발과 적합한 응용을 위한 네트워크 구축이 활발하게 추진되고 있다. 본 논문에서는 작업자의 안전을 위협하는 요소가 많은 작업현장에 센서 네트워크를 구축하여 각종 설비 현황을 모니터링 하도록 시스템을 설계하고 구현한다. 작업환경을 모니터링 하는 센서는 온도, 습도 데이터를 수집하여 싱크 노드에게 전송하고, 싱크노드와 연결된 서버는 데이터를 수집하여 사용자 인터페이스를 통해 작업자에게 제공한다. 또한, 작업현장에서 발생하는 디지털 데이터는 작업의 효율성을 높일 수 있도록 센서네트워크를 경유하여 전달된다. 제안하는 센서 네트워크는 음식물 폐기업체에 적용되어 음식 폐기물의 온도와 습도를 모니터링하고 업체에 출입하는 트럭의 중량 정보를 전송하여 작업의 편의성을 증대한다.
