Recently, as shown demands and the need for Cloud dig data, large-scale data centers, as well as factory unit's have also vigor. This study focuses the system design that can integrate various facilities on the data center build upon of the factory and the midsize group. Because the integrated facilities management of midsize groups should have variety of sensors and devices requires integrated monitoring system that can manage them as a whole. In this study, it constitutes a integrated model protocol interface of the various facilities, it suggests ways to avoid the errors that may occur during design to study the development and systematically carried out. For this purpose, this study provides the analysis of a failure information delivery time and integration scenario for efficient analysis and evaluation of an integrated monitoring system.

Recently, in order to increase the efficiency of the product production process, the automation of facilities and devices in the factory is in progress, and a smart factory is being built using ICT and IoT technologies. In order to organically solve many problems occurring in the smart factory, a system for monitoring the wireless communication function between facilities and devices and the manufacturing process environment of the smart factory is required. In this paper, we propose a monitoring system using a Bluetooth module, a temperature/humidity sensor and a fine dust sensor to remotely monitor the process environment of a smart factory. The proposed monitoring system collect Arduino sensor values wirelessly through Bluetooth communication.

지하구는 도시의 신경망이라 할 수 있는 통신, 전력, 상수도, 난방, 쓰레기 처리시설 등 도시 운용/관리를 위한 주요시설물을 안전하게 수용하고, 유지 관리하기 위한 시설로 IT기술을 이용하여 수용된 시설을 효과적으로 유지/관리하고, 재난으로부터 안전하게 보호함과 동시에 최소의 비용과 에너지로 수용된 시설물을 유지관리하기 위한 연구가 많이 진행되고 있다. 따라서 본 논문에서는 지하구(공동구, 통신구, 전력구)의 운용 및 유지관리와 지하구에서 발생될 수 있는 각종 재난에 대응하기 위한 지하구 운용 및 유지관리에 대해 알아보고, 지하구 내부에 수용된 시설물을 효과적으로 유지관리하고 재난에 신속히 대응하기 위한 지하구 환경모니터링 시스템에 대해 기술 하고자 한다. 지하구 환경모니터링 시스템은 지하구 내부에는 전력, 상수도, 통신, 난방 등 다양한 시설물이 수용되어 있으며, 이러한 시설물의 부식, 고장 등으로부터 보호하기 위해 지하구내부의 환기시스템의 송풍기와 지하수와 기상재해로 인한 지하구 및 수용시설물의 침수를 막기 위한 양수펌프에 대해 실시간 상태모니터링 통해 송풍기 및 펌프의 고장여부를 판단하여 관리자에게 알림으로써 관리자가 신속하게 대응 할 수 있도록 하였다. 송풍기의 제어는 지하의 내부와 외부에 설치된 온/습도 센서를 통해 지하구 내부환경을 최적으로 유지할 수 있도록 함으로써 쾌적한 지하 내부환경 유지하고, 급/배기가 필요할 경우에만 송풍기를 가동함으로써 에너지를 절약 할 수 있으며, 화재, 침수 등에 대한 재난시 환풍기의 급/배기, 정지 등을 신속하게 제어할 수 있도록 하였다. 또한 지하구내부에서 발생된 재난을 유/무선을 이용하여 신속하게 지하구 주변의 장치(U-Pole 또는 통합컨트롤러)를 통해 경보를 전파함으로써 주변 시민들이 안전하게 대피할 수 있도록 하였다. 그리고 지하구 환경모니터링 시스템을 검증하기 위해 실제 지하구 및 실험실에 시스템 및 Test Board을 설치하여 운용시험을 실시 하였다.

In this paper, we propose an Arduino-based plant monitoring system. The proposed system is based on the Arduino platform, using an environmental sensor and a pressure sensor for measuring temperature, humidity and illuminance in order to monitor the state of the environment and the facilities of the plant. Monitoring data are transmitted to a ZigBee coordinator connected to a server through a radio frequency transceiver. When using a pressure sensor and the environment sensor data stored on the host server, checking the pressure in the environment of the plant and equipment is intended to report any alarm status to the administrator. Using a grid line-based key distribution scheme, the authentication node dynamically generates a data key to protect the monitoring information. Applying a ZigBee wireless sensor network does not require additional wiring for the actual implementation of a plant monitoring system. Possible working-environment monitoring of an efficient plant can help analyze the cause of any failure by backtracking the working environment when a failure occurs. In addition, it is easy to expand or add a sensor function using the Arduino platform and an expansion board.

Globally, rising energy costs and increased energy demand are important issues for the food processing and manufacturing industries, which consume significant amounts of energy throughout the supply chain. Accordingly, there is a need for the development of a real-time energy monitoring and analysis system that can optimize energy use. In this study, a food factory energy monitoring system was proposed based on IoT installed in a food factory, including monitoring of each facility, energy supply and usage monitoring for the heat treatment process, and search functions. The system is based on the IoT sensor of the food processing plant and consists of PLC, database server, OPC-UA server, UI server, API server, and CIMON's HMI. The proposed system builds big data for food factories and provides facility-specific monitoring through collection functions, as well as energy supply and usage monitoring and search service functions for the heat treatment process. This data collection-based energy monitoring system will serve as a guide for the development of a small and medium-sized factory energy monitoring and management system for energy savings. In the future, this system can be used to identify and analyze energy usage to create quantitative energy saving measures that optimize process work.

In recent years, as safety management in underground mines has become more important in the worldwide, mine safety management technologies combining information communication technology such as real-time worker position tracking, monitoring system and equipment remote control have been developed. Wireless communication system is mainly applied to these technologies for the flexibility of network configuration. There are some cases the monitoring system was installed in domestic underground mines, but, it is necessary to develop the technology more suitable for domestic mining standard. In this study, we developed the real-time environmental monitoring system using ZigBee technology and examined the result of application to domestic limestone mine. Furthermore, applicability of the developed environment monitoring system to $VentSim^{TM}$ LiveView was checked. This study is expected to contribute to the related studies like the optimization of the ventilation system in underground mines.
