Research And Implementation Of Coal Mine Personnel Positioning System

The project is to develop a downhole personnel positioning system,combined with the actual mine underground mine,investment,the actual demand.Developed a personnel positioning system that includes downhole real-time dynamic mastering and staff time node recording.The normal production of workers in the case of work into the well,underground working hours,workplace,well time to monitor.With the underground staff to bid two-way call,suggesting that the vicinity of the sudden situation,to avoid a reasonable and so on.To ensure that the situation of workers in the underground real-time control for the ground dispatch staff to provide a fast and convenient management approach.This topic explains the coal mine personnel positioning system is composed of two parts of hardware and software.Hardware part adopts the ZigBee technology to realize the coal mine data collection of distributed automation.The software part is adopted ThinkPHP framework to develop a personnel positioning based on B/S architecture and information management system for managing hardware related data were collected.Paper first describes the current situation of study on the coal mine personnel positioning system.It is concluded that the coal mine personnel positioning system functional requirements of reality.At the same time in the system,on the basis of feasibility analysis,the method of UML use case diagram the basic function of the system are analyzed,and draw the use case diagram,for the subsequent system design in detail on the overall train of thought.After clearly understand the functional requirements of the system,start to the system design of each function module in detail.At the same time,the first database of a detailed analysis of overall demand,and then on the needs of the database to the database to an overall database logic design,construct database e-r diagram,combining database e-r chart to design a database table structure.Then,according to the business logic of the system has the function of each structure,each function of the system functions,completed the system each function module of the program interface is built and related code,can realize the function of the system design requirements.Finally,to all aspects of the test system.This topic explains the new river system from sichuan dazhou platform of coal mine well the real project,the mine for the new mine,mine personnel positioning system is completed and necessary part of the coal mine.This system according to the actual needs of the mine to realize the related features of the coal mine personnel positioning system,from the aspects of the system of test index and test data,the system has reached the expected purpose.
