Problems solved by technology

This kind of technical means has high data transmission efficiency and relatively mature technology. However, in the test of large-span scaffolding structures, as the building area continues to increase, the number of sensors and the amount of wired cables also increase sharply, which makes site layout and evacuation difficult. The workload of wired cables increases and the test cycle is prolonged, resulting in a significant decrease in efficiency, and the wiring of several kilometers of wired cables cannot even be implemented
The distribution of many wired cables is complicated and messy, and it is easy to connect the wrong wires, which will inevitably bring irreparable losses to the later data processing
Furthermore, the traditional wired cable transmission method uses analog signal transmission, which is prone to crosstalk between cables; moreover, the analog signal is particularly interfered by temperature and electromagnetic waves, resulting in the data not correctly reflecting the bridge inclination detection information

Description

technical field [0001] The invention relates to the technical field of scaffolding, in particular to an intelligent scaffolding fastener capable of measuring inclination changes. Background technique [0002] The entire life cycle of a building is divided into the construction phase and the use phase. Structural engineers usually pay more attention to the safety issues during the service life of the bridge, but tend to ignore various related structural safety, strength and stability issues faced by the bridge during the construction phase. . In practical applications, bridges seldom encounter the maximum load in design during their service life. On the contrary, in the construction process, accidental collapse accidents are often caused due to insufficient support bearing capacity. For this reason, various new steel pipe scaffolds have appeared. Especially in recent years, steel pipe supports have been gradually adopted in engineering, such as bowl buckle brackets. The bowl...
