New methods and functionalities for railway maintenance through a draisine prototype based on RADAR sensors

AbstractInspection of the railway tracks requires relying on a precise positioning system that accurately determines the location of potential failures and deficiencies. Therefore, measuring the speed and precise location of rail vehicles is essential. Many methods and approaches have been proposed, but most of them lack several conditions that do not allow them to be optimal for this task. In this paper, the authors present a novel method for measuring the speed of a train by means of the time correlation approach, by using 2‐mm wave radar sensors. Additionally, it is also an accurate positioning system because the authors prove that the track has a unique profile, sufficiently characteristic and stable over time, that serves as a distinctive signature, which can be used to locate the vehicle at any point on that track. As a result, this new methodology, combined with a laser profilometer device, can be used as an effective inspection system for cracks or deficiencies in the rails, sleepers, fastenings, bolts etc., locating them precisely on the railway track.

Fog Computing Based Hybrid Deep Learning Framework in effective inspection system for smart manufacturing

Most sensors have been taken up, which resulted in a massive data size, with the continuously growing IoT (Internet of Things) devices and communications infrastructure in development. The inspection of the manufacturer to identify product defects is one of the most common examples. In order to develop an effective inspection system with greater precision, this paper has been proposed a Fog Computing based Hybrid Deep-Learning Framework (FC-HDLF), that can find possible defective products. Since a large number of assembly lines can occur in a single factory, one of the main problems is how these data are processed in real-time. The system can handle incredibly large amounts of data by discharging the load from the central servers to the fog nodes. In this paper, there are two obvious advantages. Next, the Convolutional Neural Network (CNN) model is adapted to the fog computing environment, which improves its calculation performance considerably. The other is that a model of control is built that can display the form and extent of the defect simultaneously. A decision-making framework for multi-agents is built to ensure a production process architecture to optimize production processes.

Dispersion of Lamb waves in a honeycomb composite sandwich panel

Composite materials are increasingly being used in advanced aircraft and aerospace structures. Despite their many advantages, composites are often susceptible to hidden damages that may occur during manufacturing and/or service of the structure. Therefore, safe operation of composite structures requires careful monitoring of the initiation and growth of such defects. Ultrasonic methods using guided waves offer a reliable and cost effective method for defects monitoring in advanced structures due to their long propagation range and their sensitivity to defects in their propagation path. In this paper, some of the useful properties of guided Lamb type waves are investigated, using analytical, numerical and experimental methods, in an effort to provide the knowledge base required for the development of viable structural health monitoring systems for composite structures. The laboratory experiments involve a pitch-catch method in which a pair of movable transducers is placed on the outside surface of the structure for generating and recording the wave signals. The specific cases considered include an aluminum plate, a woven composite laminate and an aluminum honeycomb sandwich panel. The agreement between experimental, numerical and theoretical results are shown to be excellent in certain frequency ranges, providing a guidance for the design of effective inspection systems.

Multi-function optical characterization and inspection of MEMS components using stroboscopic coherence scanning interferometry

Abstract A Micro-electro-mechanical-system (MEMS) is a widely used component in many industries, including energy, biotechnology, medical, communications, and automotive industries. However, effective inspection systems are also needed to ensure the functional reliability of MEMS. This study developed a stroboscopic coherence scanning Interferometry (SCSI) technique for measuring key characteristics typically used as criteria in MEMS inspections. Surface profiles of MEMS both static and dynamic conditions were measured by means of coherence scanning Interferometry (CSI). Resonant frequencies of vibrating MEMS were measured by deformation of interferogram fringes for out-of-plane vibration and by image correlation for in-plane vibration. The measurement bandwidth of the developed system can be tuned up to three megahertz or higher for both in-plane and out-of-plane measurement of MEMS.

육안점검표 및 스마트폰을 이용한 하천제방 배수통문 육안점검시스템 개발

배수통문은 하천제방을 횡단하여 설치된 하천시설로, 연속적으로 시공되어져야 하는 제방의 특성에 반하여 불연속적인 단면을 제공함으로써 하천제방 안전성을 저하시키는 구조물로 알려져 있다. 본 논문에서는 배수통문의 효율적인 점검 체계 구축을 위하여 육안점검표 및 휴대용 단말기를 이용한 육안조사 시스템을 제시하고 향후 개선방향을 제시하였다. 제안된 육안점검표는 적용성 평가결과 간단한 육안점검에 의한 손상 파악을 통해 배수통문의 보수 계획 수립과 보수 및 정밀안전진단에 대한 투자우선순위 선정에 적용성이 높은 것으로 평가되었다. Culverts are structures constructed across river levees. Since river levees are to be constructed continuously, constructions of culvert are known to reduce the stability of river levees. In order to establish an effective inspection system of culverts, a visual inspection system using checklists and smart phone was recommended in this paper. It was determined that the recommended visual inspection checklist is applicable in establishing the investment priority based on the culvert's repair plan establishment, repair and precision safety inspection.

Active insp ection supporting system based on mixed reality after design and manufacture in an offshore structure

When inspection is conducted in the fields of design and manufacturing, how well that inspection is carried out is as important as how well the design and manufacturing are done. It is important that we consider how well a product is inspected in the offshore industry because offshore structures are operated far from center of operations. This paper presents a fast and effective inspection system to guarantee product performance after the design and manufacturing process by using Mixed Reality (MR) and Ubiquitous Sensor Network (USN).

>OFSTED: inspecting schools and improvement through inspection

Abstract Approximately one‐third of all maintained secondary schools in England, and a smaller tranche of nursery, primary and special schools, were inspected under the arrangements set out in Section 9 of the 1992 Education (Schools) Act by the end of 1994. This article reviews some aspects of quality assurance in the national inspection system in England. It looks in particular at the improvement of inspection and at improvement through inspection. Continuous improvement of the inspection system reflects feedback from key stakeholders, as well as work by OFSTED to incorporate new developments. Improvement through inspection, broadly defined, has to cover both what occurs at the individual school level and in the system at large as a result of inspection. We argue that an effective inspection system can provide a powerful incentive for, as well as directly contributing to, school improvement and development

A simplified visual inspection system using a personal computer

AbstractFor a practical visual inspection system, data processing in real time, flexibility for variety of products, and cost performance have been required. This article describes a simplified visual inspection system that has well‐balanced performance that meets these requirements. Inspection data processing by software makes the inspection system flexible. Development of a simplified pattern matching method based on limiting the inspection within the area pointed by an user and direct memory access of binary image data performs a high speed inspection function. By using a personal computer as a processor of this system, a cost effective inspection system is realized.
