In jewelry industry, the proportion of labor costs is high. Also, the production time and quality of products are highly varied depending on the workers' capabilities. Therefore, there is a demand from the jewelry industry for automation. The ear pin insertion automation system is the robot automatically inserts the ear pins into the silicone mold, and this automated system require accurate and fast hole detection method. In this paper, we propose optimal binarization method and a template matching method that can be applied in the ear pin insertion automation system. Through the performance test, it was shown that the applied method has an accuracy of 98.5% and 0.5 seconds faster processing speed than the Otsu binarization method. So, this automation system can contribute to cost reduction, work time reduction, and productivity improvement.

PLC의 도입이 10여년 남짓된 지금, 자동화의 추세는 기능의 다양함과, 빠른 제어 속도, 높은 신뢰도가 요구되어 전기적인 제어에서 전자적인 제어로 전환되어 가고 있다. 특히 주 컴퓨터와 연결하여 생산 및 판매, 관리 부시 등에 정보를 신속히 제공할 수 있어 여러모로 편리하다. 이와 같은 흐름은 전문적인 지식을 필요로 하지 않고 프로그램의 작성 및 수정이 용이하며 시스템고 장수리시 PLC의 기능에 의해 간단히 해결되고 새로운 전자제품의 개발로 점점 더 가격이 싸지 고 있다는 점을 감안할 때 FMS(flexible manufacturing system)를 실현하고자 하는 모든 기업에 그 응용이 예상된다.

In this paper, we have implemented Green House automation system. The system should be kept in optimal condition in real-time by checking the greenhouse environmental conditions in the greenhouse. In addition, it can be converted to temporarily the necessary equipment by converting to manual mode in the environment you want. Environmental data collected from the greenhouse is sent to your computer monitor, as well as it support the web-based system to enable immediate control through the web. Users can view the situation of the greenhouse in real time by using a web-based system and maintain automation features by deciding specified conditions for a greenhouse environment.

COVID-19 확산으로 인해 우리나라는 공공장소 출입 시 마스크 착용이 의무화되었고, 체온이 37.5℃ 이상일 경우 발열로 간주하여 출입을 금지함에 따라 이를 효율적으로 검사할 수 있는 자동화 시스템을 개발하고자 한다. 이를 위해 다양한 각도, 마스크의 착용 위치에 따른 자료를 수집하여 모델에 적용하였고, 실시간 영상은 96.5%의 높은 정확도를 보였고, 영상 처리 추론 속도는 28fps임을 확인했다. 본 논문은 딥러닝 알고리즘을 활용한 마스크 착용 판별 및 체온 측정 시스템을 제시한다.

A simple and very flexible automatic dipping machine was constructed for producing functional multilayer films on wide substrates via the layer-by-layer (LbL) assembly technique. The proposed machine exhibits several features that allow a fully automated coating operation, such as various depositing recipes, control of the dipping depth and time, operating speed, and rinsing flow, air-assist drying nozzles, and an operation display. The machine uniformly dips a substrate into aqueous mixtures containing complementary (e.g., oppositely charged, capable of hydrogen bonding, or capable of covalent bonding) species. Between the dipping of each species, the sample is spray cleaned with deionized water and blow-dried with air. The dipping, rinsing, and drying areas and times are adjustable by a computer program. Graphene-based thin films up to ten-bilayers were prepared and characterized. This film exhibits the highly filled multilayer structures and low thermal resistance, indicating that the robotic dipping system is simple to produce functional thin film coatings with a variety of different layers.

Prior to the introduction of automated systems such as jewelry CAD and CAM, the jewelry manufacturing industry had many originals made by hand. However, after the introduction of the automated system, original craftsmen with high technology have disappeared, and computer designers and 3D printing print engineers are taking their place. The introduction of automated systems such as CAD and CAM in the existing hand-made production line has resulted in diversification of designs and cutting-edge and specialization of jewelry manufacturing. In the domestic jewelry industry, the dependence of automation systems such as CAD and CAM in the manufacturing process continues to increase, and the situation is taking up more and more parts in the jewelry design curriculum of universities. From these results, the CAD/CAM automation system field in the jewelry manufacturing industry becomes an essential and important field in the future.

In this paper, a smart bus system that automates public bus traffic payment by applying beacon and computer vision and provides bus route information, real-time location information, getting off alarm is proposed. By using the beacon to recognize busses near the stop and to board the bus to be boarded, this system automatically processes the payment when boarding by using the distance from the beacon and the information provided by the beacon and the face comparison. After the payment processing, the system provides the route information of the boarded bus and the real-time bus location information to the user, and when the user sets an alarm using these informations, the alarm is activated when the bus leaves the bus stop.

The demands for the development of large scale software systems are being increased. Various software development methods have been introduced to meet these demands. The unit size of the codes that are reused is increasing in the development methods. These units reflect the concept of software reusability and can be identified as the object, component, and module. Recent trend in the development or a large scale software systems treats a commercial program as a unit to be reused. This approach lies along the same line as the identification of above three types of units. This paper shows how the above four types of units for enhancing the software reusability can be applied to the development of automatic graphic drawing System for a metal production.
