Distributed mine earthquake detection method and device

Abstract

The invention discloses a distributed mine earthquake detection method and device and relates to the field of underground coal mine safety monitoring. The distributed mine earthquake detection method comprises the steps that multiple channels of quake detection devices are arranged on a device or area to be detected in a distributed mode; after a server provides a starting signal, high-accuracy synchronous quake detection begins to be performed, and the acquired signal is received and processed by devices and transmitted to the cloud server through the Ethernet; the server performs data fusion analysis processing on mass information and then provides the processed information for users. Hardware of the distributed mine earthquake detection device comprises a quake detection and conversion unit, a microcontroller unit, a human-computer interaction unit, a storage unit, a communication unit, a time synchronous unit and the server. The distributed mine earthquake detection method and device has the advantages that quake signals with high sensitivity and a large dynamic range can be detected, frequency response characteristics are wide, data can be transmitted quickly in a nondestructive mode, networked synchronization and focus positioning accuracy under a distributed environment is high, and the system is high in capacity, strong in expansion capability and low in expansion cost.

Description

technical field [0001] The invention relates to the technical field of mine earthquake detection, in particular to a distributed mine earthquake detection method and device.

AI Technical Summary

Problems solved by technology

[0006] 1. Most of them still use localized, regionalized, and independent node-based layout structures, which cannot use distributed big data fusion to truly reflect earthquake conditions

[0007] 2. A small amount of distributed monitoring methods cannot guarantee the synchronization, consistency, and correlation of collected data, and the method of post-data analysis has a large error

[0008] 3. The existing monitoring network needs to be wired separately, which is costly, poor in scalability, and difficult
