Description

Technical Field

[0001] This invention relates to the field of electronic digital data processing, and specifically to a real-time monitoring system for blasting vibration in railway tunnels based on a multi-point sensor network. Background Technology

[0002] The blasting process of railway tunnels generates intense vibrations, which not only affect the surrounding environment but can also damage the tunnel structure itself. Especially in high-risk areas, excessive vibrations can trigger collapses, surface cracks, and damage to nearby buildings, seriously threatening construction safety and regional stability. Therefore, real-time monitoring and analysis of railway tunnel blasting vibrations is a crucial technical task. Traditional blasting vibration monitoring methods typically use a small number of fixed monitoring points for vibration data acquisition, resulting in limited monitoring range and insufficient resolution, making it difficult to comprehensively reflect the vibration distribution characteristics. Furthermore, these methods largely rely on manual analysis, which is inefficient and hinders timely warnings of potential risks.

[0003] The foregoing description of the background art is intended only to facilitate understanding of the invention. This description does not endorse or acknowledge any common general knowledge in the materials mentioned.

[0004] Many vibration monitoring systems have been developed. After extensive research and reference, existing monitoring systems, such as the one disclosed in CN117454114B, are found to generally include a monitoring platform, a data acquisition unit, a back-end evaluation unit, an operation monitoring unit, an acquisition and evaluation unit, a safety feedback unit, and an operation and maintenance management unit. This invention analyzes the system from the perspectives of the front end and the front end combined with the back end. On the one hand, it helps to improve the operational safety and stability of the equipment; on the other hand, it helps to improve the effectiveness and security of the collected data. At the same time, the information feedback method facilitates the safety 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, this system can only process the vibration information of the monitoring point and cannot be extended to the entire area, thus failing to provide sufficient data support for subsequent operations.
