- 本文介绍了一些结构健康监测（SHM）的结果，属于一个石砌体结构位于Gorai，西北部的孟买，马哈拉施特拉邦，印度。目标结构是全球内观宝塔。它拥有世界上最大跨度（85.15米内径）的石砌圆顶，被内观冥想者用作冥想大厅。主穹顶可容纳8000多名内观禅修者。全球内观宝塔由Pratibha Patil（当时的印度总统）于2009年2月8日揭幕。设计师通过穹顶结构方法实现了约90米的高度。这是一个独特的工程奇迹结构，具有民族和宗教的重要性。作为一种石砌结构，结构的稳定性取决于结构的几何形状。目前采用的结构健康监测主要包括主穹顶的直径监测、温度监测和湿度监测。在环境条件下记录读数。本文介绍了监测结构参数的选择、传感器的选择、传感器的安装以及数据的图形化后处理。SHM系统后来被转换为基于物联网的SHM系统，以使用单板计算机（SBC）远程访问实时数据。计划了中期监测，并根据中期监测计划的结果，计划了长期SHM的行动路线
— The paper presents some structural health monitoring (SHM) results belonging to a stone masonry structure located near Gorai, north-west of Mumbai, Maharashtra, India. The targeted structure is Global Vipassana Pagoda. It has the world's largest span (85.15 m Internal diameter) stone masonry dome which is being used as a meditation hall by the Vipassana meditators. The main dome has capacity to accommodate more than 8000 Vipassana meditators. The global vipassana pagoda was inaugurated by Pratibha Patil (then President of India), on 8th February 2009. The designer has achieved a height of approximately 90 m by dome over dome construction methodology. It is a unique engineering marvel structure and has national as well as religious importance. Being a stone masonry structure, the structural stability depends on the geometry of the structure. At present, The adopted SHM includes the main dome’s diameter monitoring, temperature monitoring and humidity monitoring. The readings are recorded in ambient condition. The paper presents the selection of structural parameter to be monitored, selection of the sensor, installation of the sensors, and post-processed data in graphical format. The SHM system was later converted to an IoT based SHM system to access the real-time data remotely using a single board computer (SBC). Medium term monitoring was planned and based on the output of the medium-term monitoring scheme, the line of action for the long-term SHM is planned
