ESICD(Electrical Signal Interface Control Document) refers to a document that describes protocols and data for communication between components consist of a system. Each component developer gathers at a specific place to conduct an integrated test for ESICD verification. In this case, it often happens that the integration test is delayed due to a simple mistake of software developers. There are two reasons for this situation: First, software developers do not perform sufficient verification because it is difficult to configure the system environment in a Lab, and second, they do not immediately find the cause of errors occurred during integration tests. Therefore, in this paper, we propose a strategy to effectively perform ESICD verification, which takes a lot of time between the production and implementation stage of the weapon system development stage and the system integration test stage.

본 논문은 IEC 61850 기반의 전력IT기기에 대한 시험 및 평가방법에 대해 다루었다. 여러 제조업체에서 제작한 IEC 61850 기반 전력IT기기는 현장과 같은 실제 사이트에서 구성된다. 현장시험(SAT: site acceptance test)은 운전하기 이전에 고객에게 확신을 주기위해 사이트에 설치된 모든 장비에 대해 시험 및 평가를 수행한다. 적합성 시험(conformance test)은 효율적인 현장시험을 위해서 수행해야 한다. 그러나 적합성시험을 통과한 장비일지라도 통합작업, 검수시험 및 운전하는 경우 문제가 발생할 수도 있다. 따라서 통합작업, 검수시험 및 운전하는 경우에 문제점을 최소화하기 위해 적합성시험뿐만 아니라 상호운용성 시험을 수행해야 한다.

In order to develope a common ground system, a general procedure language that can be used in both EGSE and MCS is primarily needed. As the first step in developing a common test and integration procedure language, KARI's ATS for AIT and MCE for GS were compared to some of the most representative languages such as PLUTO regarded European standard, STOL and ELISA and PIL. Based on the analysis, design features of developing a common test and integration procedure language were presented.

본 논문은 한국원전계측제어시스템(KNICS) 개발 사업의 일환으로 개발되는 안전등급 PLC(Programmable Logic Controller) 소프트웨어 개발 도구의 컴파일러에 대한 시험을 다룬다. 개발된 컴파일러에 대하여 외부 시스템과 연계하지 않고 내부에서 각 컴포넌트 별로 시험하는 컴포넌트 시험과 컴파일러 외부 시스템과 연계하여 시험하는 통합시험을 수행하였다. 시험 과정은 먼저 시험 계획 단계에서 시험 항목을 선정하고 각 항목 별로 사례와 시험 절차를 작성하며 이에 따라 시험을 수행한 결과를 분석하여 컴파일러의 수정 및 보완에 반영하는 것이다.

This paper proposes the environment construction and test method of system integration laboratory (SIL) and system integration test (SIT) for verification of interface between onboard equipment and ground control equipment of unmanned aerial systems (UAS). This research also describes the interface environment between subsystems built in SIL and verification methods for the systems' operation logic through simulated flights. Similarly, the paper handles the ground integration test process of UAS in the real testing environments.

It is indispensable for a missile to track a target under the flight condition since the tracking capability affects the system performance considerably. The best way to verify the tracker's performance is flight test while it costs too much. Consequently, captive flight test or CFT has an important role in the development of a missile system. CFT, however, cannot simulate missile dynamics and is an offline and open-loop test. In this paper, we propose a new integrated-flight simulation(IFS) method using CFT imagery to overcome the limitation of synthetic image-based IFS method. This method increases the utilization of CFT's outputs and compensates the reality of imagery which lacks in the synthetic image-based IFS. Using this method make it possible to verify the system capability in various simulation modes.

The Propulsion System Test Complex(PSTC) was constructed for the verification test of each stage's propulsion system of KSLV-II. Main Control System(MCS) is the system to operate the onboard equipment and the ground equipment of the PSTC simultaneously. This paper describes the critical design, the development status, and test results of Main Control System. The MCS will be used for the interface connection between ground control systems and onboard equipment. Test sequence and operation process of the Work Manager will be conducted by MCS.

This paper discusses a tester of functionality and call processing performance, based on the MEGACO/H.248 protocol that both IETF and ITU-T recommend as a media gateway control protocol, of both a media gateway controller and an access gateway which constitute a next generation convergence network. Effective methods, a functional architecture and implementation for such testification are provided. Especially included are not only a virtual emulation function of analog subscriber lines connecting to an access gateway, but also a tester emulated as a counter system of the protocol for the testifying a media gateway controller and an access gateway system.
