본 연구에서는 익일부하예측 기능을 갖는 빌딩에너지관리시스템을 제시한다. 기존의 빌딩에너지 관리시스템은 빌딩내의 다양한 인프라를 이용하여 에너지를 감시 한다 그러나 이러한 시스템을 구현하기 위해서는 많은 인프라 구축비용이 소요 되어, 에너지 절감을 위한 인프라 구축비용과 실제 절감된 전기 요금을 비교 할 경우, 에너지 절감을 위해 투자한 비용을 전기 요금 절약으로 회수하는데 수년이 걸리고, 또한 인프라 설비 유지 보수를 고려할 경우, 결과적으로 에너지 절약 효과가 미비하다. 따라서 본 연구에서는 보다 저렴하고 합리적인 방법으로 빌딩의 에너지 소비를 억제할 수 있도록, 기상청데이터와 한전의 ISmart 데이터를 기반으로 데이터마이닝기법을 이용하여 빌딩의 익일 부하 사용량을 예측하고 이를 기반으로 빌딩 부하의 On/Off를 수행하도록 빌딩에너지관리시스템을 구현함으로써 상대적으로 저렴한 비용으로 빌딩에너지 사용의 합리화를 이루도록 하였다.

최근 자동차산업에서의 시장의 세계화와 증가하는 고객의 까다로운 욕구는 다양한 제품의 증가와 제조업체가 공급해야 하는 생산라인의 다양한 방식의 증가로 이어지게 되었다. 또한, 자동차 생산시스템의 모듈화는 자동차부품 공급업체들의 생산시스템에도 많은 영향을 미치고 있다. 이러한 변화는 혼합형 모델 조립라인이라 불리는 비용 효율적이고 유연한 생산시스템의 구현을 요구하고 있다. 본 논문에서는 이러한 혼합형 모델 조립에서 발생하는 여러 문제점들과 이러한 조립오류를 방지할 수 있는 기술에 대해 살펴보고, 혼합형 모델 자동차부품 조립라인에서 RFID를 이용한 오류방지 모니터링시스템을 개발하였다. 특히, 자동차부품 조립현장에서 일어나는 부품의 잘못된 설치와 누락과 같은 문제점들을 최소화하기 위하여 RFID를 이용한 모니터링시스템을 개발함으로써 문제점을 해결하고 조립오류를 예방하여 기존의 시스템을 보완하고자 하였다.

A Smart TV device is either a television set with integrated internet capabilities or a set-top box for television that offers more advanced computing ability and connectivity than a contemporary basic television set. In recent years, there has been a popularity rose up on Smart TV (Smart Television) usage at home. This paper present the intelligent production status boards using features and functions of smart TV in shop floor. With the proposed status boards, we can reduce installation and operating costs of the existing production status boards. In addition, This article present the system that can line monitoring without equipments as CC TV.

Global competition to increase production output and to improve quality is spurring manufacturing companies to use condition monitoring and fault diagnostic systems for predictive maintenance. As monitoring, testing, and measuring techniques develop, predictive control of components and complete systems have become more practical and affordable. In this article, we will consider the computer based data acquisition system for condition monitoring and the condition parameter analysis techniques for fault detection and diagnostics in the machinery and briefly discuss reliability prediction and the limit value determination in condition monitoring.

In this paper, production information management systems for global manufacturing enterprises is discussed. Three basic technologies to implement the system such as networking, database, and H/W interface technology are investigated, and a web based prototype systems integrating order and production information is developed with two server computers and a educational FMS. A MMI s/w is engaged in interfacing and real-time monitoring of FMS and an intranet is used for communication between the servers and clients.

The weekly ultrasound scanner (US) observations of reproductive organs in a commercial dairy herd with the popular stanchion style management were conducted for over 26 months. Based on reproductive records, the following were evaluated: 1) the effect of postpartum period commencement of US monitoring on herd reproductive efficacy, and 2) the effectiveness of a US monitoring-based diagnosis and subsequent treatments of reproductive disorders on postpartum reproductive efficiency. The reproductive parameters of cows, which were subjected to US monitoring between Days 30-40 (Day 0 = day of parturition), Days 41-50, Days 51-60, and above Day 61, were compared. The reproductive parameters of cows diagnosed as having reproductive disorders (RD) with US monitoring before or after the first artificial insemination (AI) were also compared. It was found that the day of commencement of US monitoring in cows diagnosed with and without RD significantly affected the period towards the first AI and the open period. In particular, cystic follicles and anoestrus detected either before or after the first AI significantly affected herd reproductive efficiency. The implementation of US monitoring improved reproductive efficiency by reducing the open period and increasing the number of milking cows in the herd. The results of this field trial indicate that the postpartum reproductive management of dairy cows with the use of the US monitoring system is one strategy to improve reproductive efficiency, especially in a high-yielding dairy herd reared stanchion management style.

As the Fourth Industrial Revolution accelerating, countries worldwide are developing technologies to digitize and automate various industrial sectors. Building smart factories not only reduces costs through improved process productivity but also allows for preemptive identification and removal of risk factors through the practice of Health, Safety, and Environment (HSE) management, thereby reducing industrial accident risks. In this study, we visualized pressure, temperature, power, and wind speed data measured in real-time via a monitoring GUI, enabling field managers and workers to easily access related information. Through the work environment monitoring system developed in this study, it is possible to conduct economic analysis on per-unit basis, based on the digitization of production management elements and the tracking of required resources. By implementing HSE in shipyards, potential risk factors can be improved, and gas and electrical leaks can be identified, which are expected to reduce production costs.

The manufacturing equipment on most shop floors consists of numerical control machines, and the condition of each piece of equipment is monitored and controlled by an internal sensor or programmable logic controller (PLC). To control and monitor production lines that consist of an equipment or production module, a separate control and monitoring system such as a manufacturing execution system should be introduced. However, there is no standardized system, and it is costly and difficult to build a system for small or medium-sized plants. In this paper, a PLC-based supervisory system for operation control of a group of production machines is proposed, and the developed PLC-based system is evaluated by applying it to a computer numerical control machine.

In this paper, we standardized the water operation system picture, process control logic, realtime database and system configuration. All aspects, including monitoring & controlling processes, symbols such as pumps, valves and pipes were standardized. As a result we have developed a specialized Integrated water operation system, iWater. We have developed a variety of advanced application programs that are essential for water treatment systems, such as IWS (Integrated Warning system), MBO(modbus opc)/LSE(LS ethernet) driver, video monitoring, self diagnosis system, network monitoring, etc. IWS prevents water supply accidents by using a variety of alarms and warning messages. Drivers have the flexibility to communicate with other 3rd party systems. We expect that iWater will eliminate any concerns regarding water-related issues while also promoting the production and fair distribution of clean water.
