The Design And Implementation Of Coal Mine Dynamic Disaster Monitoring System

Dynamic disaster is one of the most serious accidents in coal mines.Due to the depth of coal mining has increased in recent years,the frequency of underground dynamic disasters has also increased.When the dynamic disaster occurs,the roadway and working place under the coal mine can be destroyed instantaneously.The ejected coal and rock caused roadway blockage,equipment damage and even casualties.Because the characteristics of underground power disasters and natural earthquakes are different,how to design a real-time effective coal mine dynamic disaster monitoring method has always been a hot issue in the field of coal mine disaster prevention.With the rapid development of the computer field in recent years,advanced sensing technology and computer processing technology provide the possibility and technical basis for dynamic disaster monitoring,and the use of information technology to achieve monitoring of coal mine underground power disasters is also receiving more and more attention from experts in related fields.This paper designs and implements a coal mine power disaster monitoring system,and applies it to many coal mine groups in Pingdingshan Pingmei Group 11 Mining Area and so on.Based on the actual demands of the mining area,this paper designs and develops the software based on the hardware already deployed.The hardware part of the system consists of the monitoring station for collecting the sensing data,the wireless bridge for data transmission,and the central machine for calculation and display,which can realize the data transmission from the station to the central machine.The system software part consists of a first-level real-time monitoring module and a secondary data analysis module.The first-level real-time monitoring module is composed of a data stream conversion processing module,a core magnitude positioning calculation module and a real-time monitoring visualization module.The data stream conversion processing module uses multiple threads to time-align the data and uniformly read the sensing data;the core magnitude positioning After the calculation module obtains the sensory data,it uses the algorithm provided by the experts in the coal mine field to calculate the position,time and magnitude of the microseismic.The real-time monitoring visualization module adopts the B/S architecture design,displays the relevant detection data through the browser,and adopts the waveform diagram and The mine map map assists the monitoring personnel.The secondary data analysis module consists of a historical data analysis module and a data analysis visualization module.The historical data analysis module stores the microseismic data of each mining area into the database,and the data analysis visualization module is responsible for visually presenting the data to the analyst.According to the software engineering development process,this paper introduces the system in detail from five stages: requirements analysis,overall design,detailed design,implementation and testing.
