Research And Implementation Of The Personnel Position System Based On LBS

With the development of infinite communication and positioning technology, the development of LBS in the mobile data services has been rapid development. Users can learn about the surrounding situation by using a wireless device with a position sensing function at any time. In the daily operations of public security, it is sometimes necessary to locate the whereabouts of a specific person, so as to realize the real-time control of its whereabouts and to query the running track of a specific time period. At the same time, by setting the corresponding boundary, it can be able to carry out real-time warning when the specific personnel cross the border.In this paper, based on the research background and research status of mobile Internet application based on LBS, this paper analyzes the functional requirements and non functional requirements of the system, and provides a framework for the personnel positioning system based on LBS. The system includes three subsystems: mobile client, server and location query service. Mobile client is responsible for data acquisition and auxiliary functions, the server is responsible for data storage and location query service is responsible for the presentation of data. Next, this paper on the three subsystems design, elaborated on the mobile client positioning, map display, geocoder is reverse coded, the search path, distance calculation, reaching warning lamp function realization method, the server socket communication, location information storage storage design method and the corresponding functions of the location query server design method. Finally, the paper takes the example to explain the operation of the system and optimizes the system.The running results show that the system can meet the business needs of the specific personnel in the public security operations, and has good openness and scalability.
