The Research Of GPS Vehicle Monitor Information Management System

GPS Vehicle Monitor System can real-time monitor the vehicles'position and state by position technique, communication and E-map display. As one of the most parts of GPS Vehicle Monitor System, GPS Vehicle Monitor Information Management System can receive and store the monitor record, dispay and print the monitor record. It is helpful to administrate and attemper the vehicle, and plan the conveyance. It is significant to development a GPS Vehicle Monitor Information Management System to increase the manage level and the benefit of enterprises.With a view to the disadvantage of the former GPS Vehicle Monitor System which has low speed of response, not reliable and safe enough, a new design of GPS Vehicle Monitor Information Management System which based on Oracle database and the improved three layer structure framework is proposed. In this thesis, the database of GPS Vehicle Monitor Information Management System is designed, the design of the man-machine conversation interface and the software of the database server, also the software of the mid-ware are accomplished.An improved and logical three layer structure framework is used to utilize the resource of the system efficiently, balance the load, and improve the expansibility of the system; powerful Oracle database is used as background database to provide high performance service to the system which has numerous users and large-scale; encrpytion arithmetic of communication data is designed to ensure the safty of GPS Vehicle Monitor Information Management System communication; the usage of fire wall, system privilege management and data backup improved the safty of the Information Management System database; high usability design is realized by Oracle Data Guard; optimization of the Information Management System made the whole GPS Vehicle Monitor System persistent, stable and high quality.This thesis consists of five chapters. The first chapter introduces the development and the main technologys of GPS Vehicle Monitor System, summarizes the function of GPS Vehicle Monitor System, indicates the research background and the main work of this thesis. The second chapter expatiates the structure and the principle of GPS Vehicle Monitor System, introduces the basic function of the in-vehicle terminal and the Information Management System. In the third chapter, the design of the GPS Vehicle Monitor Information Management System is researched. It includes the basic...
