Description

Technical Field

[0001] The present invention relates to the technical field of structure monitoring, and in particular to a method and system for monitoring deformation of civil engineering structures. Background Art

[0002] Civil engineering structure refers to a combination of load-bearing components made of various building materials connected to each other. It not only meets the functional and performance requirements of the project, but must also be safe, applicable and durable during its service life. Monitoring the deformation of civil engineering structures is to continuously observe, analyze and predict the changes in shape and position of buildings or structures under various external forces.

[0003] Application No. CN202210643913.X discloses a civil engineering structure deformation detection system and method, which includes an acquisition module for obtaining the actual structural information of the civil engineering structure to be detected; and a retrieval module for obtaining the initial structural information of the civil engineering structure. The retrieval module can synchronously obtain the initial structural information of the civil engineering structure to be tested during detection, thereby providing a certain comparison effect for deformation detection and improving the accuracy of deformation judgment; the traceability module obtains the ledger information of the civil engineering structure to be tested, which can be directly traced back to the relevant information of the structure, thereby facilitating subsequent accountability. The overall functionality of the system is strong and the use effect is good.

[0004] After searching the above patents, it was found that there are some deficiencies in monitoring the deformation of civil engineering structures: 1. When monitoring the deformation of water and wood engineering structures, the existing technology usually adopts precise leveling and trigonometric height measurement, etc. The monitoring accuracy of these devices may be affected in extreme environments or complex terrain conditions, especially when measuring in mountainous areas or deep valleys, obstructed vision may cause measurement errors, and these errors cannot be predicted in real time according to the environment or complex terrain, resulting in a decrease in the accuracy of monitoring the deformation of civil engineering structures; 2. When monitoring the deformation of civil engineering structures, it is impossible to switch in real time in multiple directions and multiple pitch angles, resulting in monitoring blind spots when monitoring the deformation of civil engineering structures, and the timeliness and effectiveness of the monitoring of the deformation of civil engineering structures cannot be guaranteed, further affecting the monitoring accuracy; 3. When monitoring the deformation of civil engineering structures by switching in multiple directions and multiple pitch angles in a timely manner, the multiple data that appear cannot be collaboratively analyzed to form the final optimized value of the deformation adjustment of the civil engineering structures, resulting in the inability to obtain the correction value in time after the abnormal deformation of the civil engineering structures, affecting the timeliness of the correction of the deformation of the civil engineering structures.

[0005] Therefore, a method and system for monitoring deformation of civil engineering structures are proposed to solve the above problems. Summary of the invention
