Abstract

The invention relates to the field of robotics technology, in particular to a system for monitoring the stress state of a steel structure throughout the life cycle of a station building in a severe cold region, comprising a monitoring part, a calculation processing part and an early warning evaluation part; the monitoring content of the monitoring part includes structural stress and strain monitoring, wind power Monitoring and structural temperature monitoring; the calculation processing part includes a receiver for receiving data, a single-chip microcomputer for data processing, and a correction module for data correction; the early warning evaluation part includes a reliability analysis module, a reliability evaluation module and a lifespan The output ports of the period analysis module, the reliability evaluation module and the life cycle analysis module are jointly connected to the early warning module; the present invention can greatly improve the accuracy of monitoring data, and can better monitor the stress condition of the steel structure of the station building, considering the actual situation The effect of temperature load can better simulate the actual stress situation; at the same time, it can also improve the reconstruction accuracy of missing data.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a system for monitoring the stress state of a steel structure throughout the life cycle of a station building in a severe cold area. Background technique [0002] Since the 21st century, with the rapid development of various science and technology, people's demand for steel structures such as airports, station buildings, gymnasiums, museums, expo halls and other large-scale public building structures is increasing. Therefore, steel structures have developed rapidly. The structural types and spatial layout of large-span spatial structures are gradually becoming diversified, and their design theory and construction technology have been developed to varying degrees. Although the space structure with larger span has its unique advantages in force, it is more complicated, and its safety issue still needs special attention. [0003] In the safety accident of steel structure, due to imp...

Problems solved by technology

[0007] The present invention proposes in view of the background technology that when the station building is located in a severe cold area, the steel structure material will generate temperature stress due to thermal expansion and contraction, which will affect the stress state of the structure, resulting in a large error problem in the stress monitoring data, and Due to sensor failure, energy interruption, communication failure, accidental destruction and other factors, it will lead to incorrect data or even data loss. A friction model modeling and friction torque compensation based on 5G and cyclic neural network is designed. method
