  • 본 논문은 다중 모듈 통합형 태양광 발전 시스템의 발전 단가를 낮추기 위한 MPPT(Maximum Power Point Tracking) 방법에 관한 것이다. 기존의 다중 모듈 통합형 태양광 발전 시스템에서는 각 모듈마다 MPPT 동작을 필요로 하기 때문에 전류센서와 전압센서를 모두 사용하며, 이는 발전 단가를 상승시키는 원인 중 하나가 된다. 본 논문에서는 시스템의 제작비용을 낮추기 위하여 다중 모듈 통합형 태양광 발전 시스템에서 상대적으로 가격이 비싼 전류센서의 사용을 줄여, 여러 개의 모듈에서도 하나의 전류센서만을 사용하는 MPPT 방법을 제안하고 PSIM 시뮬레이션과 실험을 통해 입증하고자 한다.

  • In this paper, we propose the Agricultural Environment Monitoring System based on Sensor Network which can collect information of crop cultivation environment and monitor it in real-time by using various environment sensors. Existing wireless sensor nodes, based on the sensor network, require extra conversion/control module depending on the characteristics. To solve this problem, we developed an integrated sensor module which can integrate various kinds of sensors used to obtain the necessary information for the area under crop cultivation. In addition, we developed sensor networks monitoring system which is suitable for an integrated sensor module. To verify the operating status of the proposed system, an integrated sensor node is installed in the test environment so that it can sense information of the environment and monitor it in real-time.

  • This paper presents a multimodal emergency recognition system based on visual information, audio information and gravity sensor information. It consists of video processing module, audio processing module, gravity sensor processing module and multimodal integration module. The video processing module and gravity sensor processing module respectively detects actions such as moving, stopping and fainting and transfer them to the multimodal integration module. The multimodal integration module detects emergency by fusing the transferred information and verifies it by asking a question and recognizing the answer via audio channel. The experiment results show that the recognition rate of video processing module only is 91.5% and that of gravity sensor processing module only is 94%, but when both information are combined the recognition result becomes 100%.

  • Recently, intelligent surveillance camera systems are needed popularly. However, current researches are focussed on improvement of a single module rather than implementation of an integrated system. In this paper, we implemented a wireless surveillance camera system which is composed of face detection, and using motion sensor. In our implementation, we used a camera module from SHARP, a pair of wireless video transmission module from ECOM, a pair of ZigBee RF wireless transmission module from ROBOBLOCK, and a motion sensor module (AMN14111) from PANASONIC. We used OpenCV library for face dection and MFC for implement software. We identified real-time operations of face detection, PTT control, and motion sensor detecton. Thus, the implemented system will be useful for the applications of remote control, human detection, and using motion sensor.

  • The development trend of jet fighter's avionics system architecture is the digitization of subsystem component functions, increased RF sensor sharing, fiber optic channel networks, and modularized integrated structures. The avionics system architecture of the fifth generation jet fighters (F-22, F-35) has evolved into an integrated modular avionics system based on computing function integration and RF integrated sensor systems. The integrated modular avionics system of jet fighters should provide improved combat power, fault tolerance, and ease of jet fighter control. To this aim, this paper presents the direction and requirements of the next-generation jet fighter's avionics system architecture through analysis of the fifth generation jet fighter's avionics system architecture. The core challenge of the integrated modularized avionic system architecture requirements for next-generation fighters is to build a platform that integrates major components and sensors into aircraft. In other words, the architecture of the next-generation fighters is standardization of systems, sensor integration of each subsystem through open interfaces, integration of functional elements, network integration, and integration of pilots and fighters to improve their ability to respond and control.

  • The monitoring of environmental information (e.g. noise, dust, vibration, temperature, humidity) is crucial to the safe and sustainable operation of a construction site. However, commercial sensors exhibit certain drawbacks when applied on-site. First, the installation cost is prohibitively high. Second, these sensors have been engineered without considering the rugged and harsh conditions of a construction site, resulting in error-prone sensing. Third, construction sites are compelled to allocate additional resources in terms of manpower, expenses, and physical spaces to accommodate individual sensors. This research developed an integrated sensing module to measure the environmental information in construction site. The sensing module slashes the installation cost to 3.3%, is robust enough to harsh and outdoor sites, and consolidates multiple sensors into a single unit. The sensing module also supports GPS, LTE, and real-time sensing. The evaluation showed remarkable results including 97.5% accuracy and 99.9% precision in noise measurement, an 89.7% accuracy in dust measurement, and a 93.5% reliability in data transmission. This research empowers the collection of substantial volumes and high-quality environmental data from construction sites, providing invaluable support to decision-making process. These encompass objective regulatory compliance checking, simulations of environmental data dispersion, and the development of environmental mitigation strategies.

  • 통합항해시스템이라 함은 자동화된 선박의 운용에 관한 것으로, 다양한 항해 센서(GPS, Gyro, Speed Log, echo sounder)를 이용하여 선박의 항해에 필요한 각종 정보를 입수하여 최적의 항로를 설정해주고, 운항의 안정성과 효율을 극대화시키는 시스템을 지칭한다. 즉, 선박의 운항에 필요한 다수의 모듈들을 독립적으로 운용하는 것이 아니라 이를 통합된 형태로 운용하여 효율을 극대화시키는 시스템이 통합항해시스템이라 할 수 있다. 통합항해시스템은 다양한 항해 센서들과 항해 시스템으로 구성되며, 다양한 항해 데이터들은 항해 센서로부터 수신하여 처리하는 동작을 수행한다. 즉, 통합항해시스템은 다수의 센서들로부터 수신된 정보를 평가하고 잠재적 위험과 무결성 저하에 대해서는 적절한 경고를 제공하여야한다. 따라서, 항해센서 데이터의 유효성(Validity) 및 모호성(Plausibility) 검사와 무결성 감시(Integrity Monitoring)는 통합항해시스템의 필수적 기능이라 할 수 있다. 본 연구에서는 IEC 61924 규격에 의한 항해센서로부터 수신된 항해데이터가 정확하고 유효함을 가지는 지에 대한 가치평가의 척도와 독립적인 데이터 소스로부터 데이터를 비교하여 검증하는 무결성, 정확도 이내의 정보를 완전하고 명확한 방법으로 사용자에게 제공하는 무결성 감시의 방법을 제시하며, 항해센서들에 의해 취득되는 항해 데이터의 무결성 검사를 통한 유효성, 적용가능성, 무결성의 평가방법을 기술한다.
