| Aiming at the problems of low management efficiency of station inspectors and prone to safety accidents,in order to strengthen the work supervision and safety protection of station inspectors,Bluetooth positioning technology is used to collect and display the location information of station inspectors in real time,In order to improve the management efficiency of station patrol personnel and strengthen the safety management of station patrol personnel.Starting from the positioning requirements,the basic layout idea of dividing the positioning area into positioning units is determined.For the positioning unit,the positioning effect under different layout methods and different layout spacing is studied.For different types of stations,the layout scheme of positioning unit for different stations is proposed.According to the actual needs,the basic positioning accuracy requirements are determined.According to the layout scheme,the basic idea of first determining the positioning unit and then positioning inside the unit is determined.The unit matching algorithm,cyclic triangular centroid algorithm,adverse situation compensation algorithm and inertial position estimation algorithm are designed,and the algorithm flow in different cases is determined.The station patrol personnel management system is designed and developed,and the smart watch application software based on Android platform and the server application based on spring boot framework are compiled.Finally,after the system test,the functions of the system are complete and operate normally.It can obtain the location information of patrol inspectors in real time.It is a feasible scheme for station patrol management. |
