摘要

The cable is a key component of large-span cable-stayed bridges to ensure structural safety. Real-time monitoring and intelligent assessment of the cable condition is crucial for the safe operation of bridges. Latest technologies such as the Internet of Things (IoT) provide more convenient means and tools in this field. This paper analyses the hierarchical structure and key technologies of the Internet of Things, studies the sensors for cable force collection, and proposes the scheme and engineering key points of the monitoring system based on IoT technology. The test results show that the system can effectively and accurately monitor bridge cable forces and has good application value for improving bridge safety and reducing construction costs.
