| Vehicle traveling data recorder is a digital electronical apparatus that is used to record such data as velocity, time and mileage and the information referring to the status of the vehicle. These data can be output to the computer through serial interface. With analyzing the data that has collected for special purpose, the management software of vehicle traveling data recorder can reappear, analyze and supervise the course of automobile's traveling in various states.The thesis focuses on the implementation of GIS(Geography Information System) in the management software of the vehicle traveling data recorder, furthermore this software implements the network management of GIS. In order to avoid system mistake due to opening the illegal file by client, the author designs a model of two levers server based on analyzing the present network of GIS;in the implementation of GIS, the author adopts SuperEngine as the developing platform and realizes the second integrated development, and moreover adds the function of replaying of historical running data, and then analyzes and studies the handling unusual data in the function of replaying of historical running data, chooses polynomial curve fitting arithmetic to deal with unusual data based to ensure the continuity of curve. Through the designing of the frame of network communication and communication protocol related to vehicle traveling data recorder, server and client, the software finally implements the network management of GIS in client, replaying of historical running data, and supervising of the real-time information . |
