Application And Research Of Personnel Security System

Through the discussion and research on social public safety,this paper designs and implements the personnel security system from the perspective of people's personal security.This paper discusses the architecture design of the system software.The architecture and function design of the system includes the structural function design of the service management platform,user client and security client.The core of the overall design process of the system includes security customization,one-button rescue,The core business such as Ping An escort,and finally the test results of the personnel security system were explained.The order matching problem encountered in the system development process is extended to the closest problem based on the GeoHash algorithm.Firstly,the neighboring point search strategy is introduced to introduce the GeoHash algorithm,and the latitude and longitude coordinates of the points in the region are provided by assuming that the user initiates a rescue request.Through the experimental calculation,the final result is that the Geohash algorithm can provide higher precision while consuming less resources.Through the use of the security personnel encountered in the application can exceed the route specified by the navigation,the idea of the improved A* algorithm based on the bifurcation road segment is proposed,and the improved path planning is established through the open source path planning engine OSRM simulation,and the verification verification algorithm model is established.Imperfect,need to collect more analog data.The main innovation of this thesis is to apply and improve the best advantage problem in the matching region of GeoHash algorithm and the improved A* interactive path planning algorithm in the personnel security software,and find the deficiencies in the established model.Through the practical application verification and the application scenario of the research algorithm,the applicability of the algorithm can be verified by the actual theory,so that it can be applied not only in the personnel security system software studied in this paper,but also in the related fields of agricultural engineering and information technology.Widely used,the research results of path planning in agricultural production robot research can also be applied.The common research content in the spatial index matching the closest point problem is also applicable to the research of agricultural machinery automatic fertilization and unmanned spraying pesticide.
