Abstract Safe exploitation of a building requires constant monitoring of both the object itself as well as its surrounding through the monitoring system. These tasks find particular applications when operating large construction projects, especially in urbanised areas. Besides the warning function and undertaking reactions, the monitoring system allows for recording changes in object geometries to assess their stability. To conduct monitoring, various sensors and instruments that work within the applied measuring systems can be used. As an example, one can mention precise inclinometers (‘electronic bubbles’) allowing for accurate determination of inclination angles. The paper discusses the precision and functional aspect of the original inclinometer developed and improved by the authors. The working principle of the device is based on optical fibres, light projection and its detection on a CCD camera objective. The presented issue is a low-cost solution offering high measurement accuracy, which may be used in structural monitoring of objects located in the impact zone of a deep excavation or other nearby ongoing investments.

用于结构监测的原始低成本光纤倾角仪的准确性和功能评估

摘要 建筑物的安全开发需要通过监控系统对对象本身及其周围环境进行持续监控。这些任务在运营大型建筑项目时特别适用，尤其是在城市化地区。除了警告功能和进行反应外，监控系统还允许记录物体几何形状的变化以评估其稳定性。为了进行监测，可以使用在所应用的测量系统内工作的各种传感器和仪器。例如，可以提到精确的倾角仪（“电子气泡”），可以准确确定倾角。本文讨论了作者开发和改进的原始倾角仪的精度和功能方面。该设备的工作原理基于光纤、光投射及其在 CCD 相机物镜上的检测。所提出的问题是一种提供高测量精度的低成本解决方案，可用于对位于深坑或其他附近正在进行的投资的影响区中的物体进行结构监测。
