Design And Implementation Of Monitoring And Early Warning System For Mine Gas

In recent years,with the rapid development of science and technology in our country and the continuous improvement of national security awareness,the casualty rate caused by gas accidents in China has decreased.However,its catastrophic consequences cannot be underestimated.The existing mine gas detection systems have been unable to meet the needs of enterprises and front-line workers.Therefore,to meet the safety needs of enterprises for mine operation safety,a mine gas monitoring system proposed by Hebi Dezheng gas detection co.ltd.has been optimized,upgraded and serve other related enterprises.As an important part of the above-mentioned mine gas monitoring and early warning system,the software service subsystem designed in work includes four parts: information monitoring subsystem,early warning information subsystem,equipment verification subsystem,and background management subsystem.This software service subsystem can monitor real-time data.,historical data,historical alarm data,real-time warning data,achieve chart display and equipment verification functions.The workflow of this thesis is as follows:(1)Requirements analysis phase: identifying system requirements and analyzing the model by communicating with relevant technical personnel of Hebi Dezheng Gas Detection Co.,Ltd.through on-site field surveys and on-site talks;by using the use case diagrams,domain models,and system sequence diagrams in UML.(2)Preliminary design phase: completing the system’s physical topology diagram,the system structure model,and the database physical structure to establish the core of the system;Detailed design stage: the business logic in detail by using class diagrams,sequence diagrams,and flowcharts;implementing the description by Java web development technology.(3)Finalization: Proposing plans to resolve the technical difficulty in the early warning system.In order to meet the different requirements of different early-warning levels,the system was designed to establish and implement three warning levels,including safety,attention,and emergency,under three early-warning modes-stable,disturbance,and aggregation modes.The mine gas monitoring and early warning software service subsystem has passed the acceptance test of Hebi Dezheng Gas Detection Co.,Ltd.The subsystem has been confirmed to fully meet the user’s software requirements.After establishment of the basic hardware environment of the mine gas monitoring and early warning system,the software service subsystem can be successfully deployed and commissioned.
