Design And Implementation Of Personnel Positioning Scheduling System Based On WebGIS

With the rapid development of smartphone software and hardware technology, Organic combination of mobile Internet and geographic information systems forms the command and dispatch applications for mobile phones and other portable devices. Positioning scheduling system is the organic combination of computer software technology, WebGIS technology, GPS technology and wireless communication technology and other advanced technologies. The paper is conformed to the trend of the development of WebGIS technology and the requirements of positioning scheduling system, and integrates the two means organically to perfect function of positioning scheduling system。 Then, completed the detailed design and implementation of personnel positioning scheduling system based on WebGIS.This paper firstly has presented the overall design of the positioning scheduling system, in accordance with the requirements of the entire system designed the system architecture. Divided into three functional modules, personnel positioning functional subsystems based on Google Maps, personnel information management system and communications services subsystem, the paper has realized the design of the public database server based on these demand.Then, the paper described the detailed design of the three major functional subsystems of the positioning scheduling system.(1) For the personnel positioning functional subsystems based on Google Maps API technology, firstly introduces the technical principles of the Google Maps API and objects, methods and properties, the paper has realized the main functions according to the basic positioning, historical track playback and picture display of the subsystem. On this basis, this paper has presented the implementation process on the server and client according to the functions, and emphasized the Ajax communication process of the Google Map API and the web server.(2) For the personnel information management subsystem, its major function is the realization of the administrator could distribute the account and password to the dispatcher and mobile terminal staff, and it’s responsible for its file information editing and management.(3) Firstly, compared Socket and HTTP network communication, opt for the latter to implement server-side and mobile terminal communication, detail authentication and authorization process for login request of client, location information and image information received and stored procedures. Finally, this article was summarized and proposed research directions in the future according to the system deficiencies.
