AI Technical Summary

Technical Problem

In existing downhole operating environments, there is a lack of effective coupling analysis between environmental risks and personnel vital signs, which makes it impossible to accurately identify the correlation between environmental risks and personnel anomalies, and makes it difficult to handle periodic and non-periodic events, thus limiting the accuracy and timeliness of risk assessment.

Method used

By acquiring vital signs and environmental information of personnel underground, anomaly detection algorithms and Fourier decomposition are used to determine the sequence of periodic and non-periodic abnormal events, and a comprehensive evaluation is conducted by combining data from wearable devices and environmental sensors.

Benefits of technology

It achieves comprehensive mine risk assessment, avoids the problem of one-sided risk assessment results caused by a single assessment indicator, solves the problem of lack of periodic analysis in mine risk assessment, and has the function of avoiding false alarms or omissions.

Abstract

The application relates to the technical field of mine risk analysis, in particular to an underground environment risk hidden danger and personnel vital sign coupling analysis method and equipment. The method comprises the following steps: acquiring vital sign information and environment information of underground personnel to determine a first abnormal time point sequence, thereby determining a related risk sequence, performing Fourier decomposition on the risk sequence and the first abnormal time point sequence, and determining a periodic abnormal event sequence and a non-periodic abnormal event sequence; the personnel vital sign information is collected through a wearable device; the environment information comprises gas concentration, temperature, humidity, ventilation volume, carbon monoxide concentration, dust concentration and carbon dioxide concentration. The application plays a role in improving the comprehensiveness of mine risk assessment, can avoid the one-sided problem of risk assessment results caused by single evaluation index, solves the problem of lack of periodic analysis in related mine risk assessment, and has the role of avoiding false positives or false negatives in mine risk prediction.
