AI Technical Summary

Technical Problem

In existing similar simulation test methods, there is a lack of verifiable mapping relationship between the control input and output disturbance of the vibration generating device. It is difficult to stably convert the on-site blasting vibration record, blasting energy characteristics and waveform parameters into an executable excitation sequence. The correlation between stage number, event number and timestamp between stage condition record and multiple original data packets is inconsistent, resulting in insufficient traceability and verifiability of the coupling analysis result packet.

Method used

The monitoring unit collects output disturbances, establishes a control input-output mapping table, maps blasting energy characteristics and waveform parameters to excitation sequences, generates disturbance loading configurations, and records stage number, event number, timestamp, excavation volume and excitation sequence version in the stage working condition record. It writes unified time base and sensor deployment metadata, performs time alignment, noise suppression, feature extraction and co-evolution analysis, and outputs a coupling analysis result package.

Benefits of technology

It solidifies the correspondence between the control input of the vibration generator and the output disturbance on the similar simulation platform, reduces the situation where disturbances cannot be verified due to differences in device status and input settings between different test batches, ensures a unified index and traceability link for multiple monitoring data, and supports consistent analysis and verification of multiple responses to the same event.
