Design And Implementation Of Underground Personnel Positioning System

In order to reduce the accident probability of underground workers in coal mines,the underground personnel positioning system has become an important part of the "six systems"to avoid safety.However,in engineering practice,the system still has some functional and performance problems.In view of the existing problems,this paper studies the underground personnel positioning system from three aspects:demand,design and realization.The specific work is as follows.First,based on the analysis of the tasks and characteristics of the underground personnel positioning system,the system's functional requirements are positioned in five aspects:alarm,attendance,real-time monitoring,report query,and management,and non-functional requirements such as compatibility,performance,and security are put forward.It lays the foundation for the design and realization of underground personnel positioning system.Secondly,according to the requirement of the system,the general framework of the system and the design ideas of each functional module are put forward.On this basis,we define the classes required for the five functional modules and implement the corresponding logical design based on the time series diagram.Based on the E-R diagram,the database and table of underground personnel positioning system are designed,and the optimization measures are put forward.Thirdly,using the system design framework as a guide,combined with JSP + MySQL +Web technology,the five functional modules are implemented from class diagrams,flow charts,core code,and web implementations,and their test environments are pointed out.Through the above work,the design and implementation of the underground personnel positioning system are completed,which provides a platform for improving the safety of underground workers in coal mines.However,there are still some bugs that have not been repaired during the test process.Later,they will gradually be perfected,and they will continue to work hard to promote their true integration into the six systems.
