Mine Rescue Personnel Rescue System Design And Implement

The coal mining industry is recognized as a high-risk industry.Most of the workplaces are hundreds of meters underground and the activity space is limited.The complex work of coal mines,the changing geological conditions,the poor production conditions,and the poor technical equipment are often threatened by water,fire,gas and natural disasters.Since the coal mining face is generally in a deep underground position,if the mine disaster occurs,the ambulance personnel may cause secondary damage during the rescue process.Aiming at the current situation of wide distribution of mines,slow emergency response of rescue,lack of emergency plans,and difficult real-time monitoring of rescue sites,real-time emergency video surveillance,real-time accurate positioning of underground rescue personnel,micro-wireless audio communication,and positioning of rescue personnel are realized.The live video of the ambulance work surface,two-way voice call,to solve the related problems encountered in the search and rescue process.In order to ensure the safety of the ambulance personnel,the system can realize the positioning of the ambulance personnel.The live video of the ambulance work surface was obtained and a voice call was made to solve the related problems.The main contributions are listed:(1)Through the business analysis,the business domain model and core business processes are determined;through the functional analysis,the system use case analysis and the main use case specification are given.In the design process of the scheme,the circle determined by the distance between the base station coordinates and the base station and the tag is used,and the algorithm for finding the intersection point of the plurality of circles is used to realize the positioning of the personnel;in the system development phase,the Spring boot and the Thymeleaf Android are mainly used.Develop and implement,and use Bootstrap to beautify and perfect the interface.(2)The system mainly includes two roles:the first is the rescue personnel.When the mine disaster occurs,each rescuer carries a tag and carries a mobile base station.The Android terminal of the system is used to enter the area where rescue is needed;the positioning algorithm of the system can be used.Real-time access to the location information of the rescue personnel,and upload the coordinates and distance of the base station and the tag to the Web,and use the coordinates of each base station as the center of the circle,and draw the distance between each base station and multiple tags as a radius,and multi-circle The intersection formula calculates the coordinates of the label and displays it on the roadway map and the radar map on the Web side in real time.Once the rescuer has a secondary disaster,it can be rescued.The second is the rescue commander.The system can establish real-time calls between commanders and rescuers.It can also broadcast or single-point calls to rescuers and direct rescuers.Since the equipment carried by the rescuers has a camera,the commander can obtain real-time downhole image information by picking up the camera of the device.(3)The system implements the basic information management of roles and users,and can add,delete,modify and query the personal information of the system users.When a disaster occurs,the location of the rescuer can appear on the roadway map and the radar map in real time.The commander can actively organize the rescue according to the real-time personnel position information,which provides convenience for real-time rescue.The project realizes video surveillance of emergency rescue,real-time accurate positioning of underground rescue personnel,wireless audio communication,wireless transmission of underground rescue data,and builds a search and rescue positioning system for mine rescue personnel to realize information interconnection and meet the needs of users’ mine emergency requirements.
