Problems solved by technology

[0005] Conventional structural monitoring systems can only process the response data at the collection location, and cannot obtain the load responses of other members and nodes, and researchers often need to know more real-time information about the structure in order to comprehensively assess the overall state of the structure. grasp
Arranging more sensors and collecting boxes with more collection channels is time-consuming, labor-intensive and uneconomical, and the work efficiency is low, which limits the engineering structure monitoring system. It is the bottleneck in the further development of this field, affecting the promotion and application, and cannot Meet the needs of the market and users

Description

technical field [0001] The invention relates to an engineering monitoring demonstration platform, in particular to a real-time online intelligent monitoring demonstration platform for structural load-response changes. Background technique [0002] At present, 1. Structural load-response changes are the core content of civil and structural engineers and civil researchers. Courses on structural load-response changes, such as structural health monitoring and structural vibration control, are very important in the civil engineering teaching plan However, such courses are often characterized by being too theoretically abstract and quite different from actual engineering. Theoretical research is relatively boring and not intuitive enough, so it is not easy for learners to understand and master. In addition, due to the large size of civil engineering structures, it is difficult to demonstrate the structural load-response change system on site. It is time-consuming and labor-intensi...
