스마트시티 플랫폼은 도시내의 다양한 센서로부터 수집되는 데이터를 기반으로 도시 공간의 상황을 보여주는 시스템이다. 기존의 스마트시티 시스템들은 IoT 센서들의 정보를 모아서 보여주고 고정형 CCTV 의 영상을 관제 시스템에서 보여줌으로써, 관제사에 의한 상황 파악을 주 목적으로 개발되고 운용되어 왔다. 최근 5G 무선 통신망이 구축되면서 5G 의 edge computing 기술과 영상 정보, 센싱 정보 등 다양한 형태의 정보 분석 및 대응이 요구되고 있으며 단위 기능으로 제공되는 데이터들을 사용자의 필요에 따라 조합하여 새로운 서비스를 제공할 수 있는 플랫폼의 구조를 제시하고자 한다.

MSRDS(Microsoft Robotics Developer Studio), the robot simulation platform provides the simulation robots and environments enabling to the basic robot programming without hardware robots. In this paper, we carry the maze escaping problems to compare and analyze the performance of LRF, bumper, IR, and sonar sensor with the same condition on MSRDS(Microsoft Robotics Developer Studio) environment. To evaluate the performance of sensors, we program the simulation environments with same conditions for all sensors. We could find that the LRF sensor had the highest performance and the bumper sensor has the lowest performance on the travel time, the number of turning, and the number of collisions. It was also confirmed that IR sensor and sonar sensor had lower performance than LRF sensor on the number of turning.

최근 공공안전 분야에서는 국민의 위험상황을 분석하여 선제적으로 예측을 하여 국민의 안전을 보장하기 위한 요구사항이 대두대고 있다. 또한 스마트폰 및 스마트워치와 같은 고성능 모바일 단말 기기들의 대중화로 인해 해당 기기들에 부착된 다양한 센서 데이터들을 융복합하여 분석할 경우, 수집한 센서 데이터의 잠재적 가치를 안전보장 측면에서 사용할 수 있는 장점이 있다. 본 논문에서는 대인, 대물, 장소에 해당하는 로그 데이터들을 융복합 분석하여 보호대상자의 안전을 지원하는 다중로그 플랫폼 기반 이동경로 분석 기법을 제안한다. 다중로그 플랫폼에서 수집하는 보호대상자의 이동 경로 궤적을 활용하여 과거에 축적된 이동경로 패턴과 비교를 통해 현재 경로가 평소에 이용하던 경로와의 유사도를 추천하게 된다. 해당 이동 경로 분석 시스템은 위치기반 멀티모달 센서 데이터를 융복합 하여 보호대상자의 안전을 보장하는데 기여 할 것으로 예상된다.

This study was conducted the management of a water level through the water sensor, the waterline and the drain applied to the rice paddy. The gateway transfers the information to oneM2M(: Machine to Machine) platform of IoT(: Internet of Thing) standards to the height of the water level sensor information through the LoRa connection. Depending on the water level requested by the IoT platform, the gateway is to On or Off waterline or drain motor switch and send the information of the water level sensor. IoT platform performs the intelligent application function according to the condition of the water level.

USN(Ubiquitous Sensor Network) environment that provides the service measured from sensors in real-time the information is delivered to application service. However, domestic service, application service provider environment between providers and users, most of the research are on the service platform architecture, and process the information detected by sensors between the providers of standard services platform architecture, which is a very weak level. In this paper, we proposed new service architecture though analysis of the OGC SWE(Sensor Web Enablement) with standards and research analysis of domestic standards. And we designed and implemented to each component of provider side.

Using crowdsourced sensor data collection technique, it is possible to collect high-density ground vibration data which is difficult to obtain by conventional methods. In this study, we have developed a crowdsourced ground vibration data collection system using MEMS sensors mounted on small electronic devices including smartphones, and implemented client and server based on the proposed infrastructure system design. The system is designed to gather vibration data quickly through Android-based smartphones or fixed devices based on Android Things, minimizing the usage of resource like power usage and data transmission traffic of the hardware.
