Description

Technical Field

[0001] The invention relates to the field of electric digital data processing, and in particular to a railway tunnel blasting vibration real-time monitoring system based on a multi-point sensing network. Background Art

[0002] Railway tunnels generate strong vibrations during blasting construction, which not only affects the surrounding environment of the tunnel, but may also cause damage to the tunnel structure itself. Especially in high-risk areas, excessive vibrations may cause landslides, surface cracks, and damage to adjacent buildings, seriously threatening construction safety and regional stability. Therefore, real-time monitoring and analysis of railway tunnel blasting vibrations has become a crucial technical task. Traditional blasting vibration monitoring methods usually use a small number of fixed monitoring points for vibration collection, with a limited monitoring range and insufficient resolution, making it difficult to fully reflect the vibration distribution characteristics. In addition, these methods mostly rely on manual analysis, which is inefficient and difficult to warn of potential risks in a timely manner.

[0003] The foregoing discussion of the background art is intended only to facilitate an understanding of the present invention. This discussion does not acknowledge or admit that any of the material referred to is part of the common general knowledge.

[0004] Now many vibration monitoring systems have been developed. After a lot of searching and reference, it is found that the existing monitoring systems include the system disclosed in the publication number CN117454114B. These systems generally include a monitoring platform, a data acquisition unit, a back-end evaluation unit, an operation supervision unit, an acquisition evaluation unit, a safety feedback unit and an operation and maintenance management unit. The present invention analyzes from the perspective of the front end and the front end combined with the back end. On the one hand, it helps to improve the operating safety and stability of the equipment, and on the other hand, it helps to improve the effectiveness and utilization safety of the collected data. At the same time, through information feedback, it is convenient to carry out safe monitoring and management of blasting vibration during the equipment monitoring process, so as to ensure the stability and effectiveness of the entire blasting vibration monitoring process. However, the system can only process the vibration information of the monitoring point, and cannot be expanded to the entire area, and cannot provide sufficient data support for subsequent operations.
