Abstract: The proposed device in this paper integrates high-precision strain gauges at key points of safety ropes to capture minute deformation data in real-time. Using dedicated signal conditioning circuits and embedded algorithms, it achieves instant detection and graded warning of abnormal force states. Additionally, by employing a UWB and barometer fused positioning technology, it accurately acquires the three-dimensional spatial coordinates of anchor points. By comparing these coordinates with predefined safety zones, the system enables intelligent evaluation of anchor point validity. The research completed the hardware integration and software development of the device and built a system prototype that integrates data acquisition, edge computing, and wireless communication. Test results show that this device can effectively enhance real-time risk perception and early warning capabilities for high-altitude operations.
