Abstract

This paper presents a portable device based on an Anisotropic Magnetoresistance (AMR) sensor for Steel Health Monitoring. The system operates by detecting magnetic anomalies in ferromagnetic materials caused by strain, corrosion, etc. This sensor can have various applications in the transportation,building, and aerospace fields for safety and maintenance monitoring of ferromagnetic materials. In this work, a low-cost device, that combines a high-sensitivity AMR sensor, a microcontroller, and supporting electronics has been designed and implemented. This sensor allows the contactless measurement of the magnetic flux density along three axes, when placed above the material under test, while the microcontroller and the required electronics enable real-time analysis and monitoring of measurements. In order to house and protect the sensor under various circumstances, a 3D-printed enclosure has also been created. This device can be used along with rehabilitation techniques for treatment of defective areas of an under-test material. Its versatility allows it to be employed in a variety of testing conditions for both single-point and scanning mode monitoring. The device’s portability, ease of use and applicability to on-site measurements make it accessible to a wide range of users, requiring only a personal computer to display the measurements. Finally, measurements are presented to prove the device’s accuracy for steel health monitoring.

基于各向异性磁阻传感器的钢材健康监测装置的研制

提出了一种基于各向异性磁阻(AMR)传感器的便携式钢材健康监测装置。该系统通过检测由应变、腐蚀等引起的铁磁材料中的磁异常来工作。该传感器可在交通运输、建筑、航空航天等领域应用，用于铁磁材料的安全和维护监测。在这项工作中，设计并实现了一种低成本的设备，该设备结合了高灵敏度的AMR传感器，微控制器和支持电子设备。当放置在被测材料上方时，该传感器允许沿着三个轴对磁通密度进行非接触式测量，而微控制器和所需的电子设备可以实时分析和监测测量结果。为了在各种情况下容纳和保护传感器，还创建了一个3d打印外壳。该装置可与修复技术一起用于治疗待测材料的缺陷区域。它的多功能性使其能够在各种测试条件下用于单点和扫描模式监测。该设备的便携性、易用性和对现场测量的适用性使其适用于广泛的用户，只需要一台个人计算机就可以显示测量结果。最后，通过实验验证了该装置对钢材健康监测的准确性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
