Satellite-positioning System Of Mobile Phone Case Study Based On GPS And GPRS Technology

The main purpose of this thesis is to explore mobile phone satellite fixes position monitoring systems key technologies such as monitor the work of the principle ,hardware and software architecture, the system functions and security systems and to resolve the scheme。at the same time, the paper exemplifies the part function of the mobile phone satellite fixes position monitoring systems。In this thesis, completed the following work:1. An analysis of satellite positioning to monitor the work of the basic principles, and described the mobile phone satellite fixes position monitoring systems design thought。Be system's turn to be being composed of tripartite logically, namely GPS fixer system , geographic information system (GIS) and communication chain circuit are composed of;Talk from the hardware on made up of , be system's turn to be composed of tripartite also , be to monitor centre , communication network and mobile phone terminal。2. Studied the mobile satellite fixes position monitoring systems software architecture。The problem having discussed the systematic software population frame, has given system out the basis choosing a type ,has cited an example by way of explanation the choice problem that the server OS and the customer hold OS,and choice of database systems, GIS platforms and communications systems to carry out the detailed Analysis。3. Discussed the mobile phone satellite fixes position monitoring system's hardware selection and the principle of networking programs,and monitoring the system's basic hardware system configuration request。 4. Analysis of mobile phone satellite fixes position monitoring system function。Including the monitoring system on the composition of the function modules,examples of the monitoring system to monitor the goals and objectives of tracking, real-time scheduling, information services, remote settings, remote control, remote monitoring, and playback track, and report to the police for speeding, regional police, Emergency alarm, map editing and image back, and other monitoring functions of scheduling,to discuss the monitoring system of auxiliary functions WEBGPS as well as monitoring,and have given to problem such as administration upkeep and system interface turn discuss ,and other issues to discuss。5. On the mobile phone satellite fixes position monitoring system an indispensable link in the GIS to carry out a detailed investigation and discussion。And the accuracy having introduced geographical feature map choice ,coding and geographic features precision, described by the raw data acquisition,analysis,processing and topographic map of the integration steps constitute the basic map data processing and map the basic data quality control process to give details Note。6. Has set forth the mobile phone satellite fixes position monitoring system the safety of the system。The application safety and network safety problem that supervisory control system respectively right away give analysis。This article related to the mobile phone satellite fixes position monitoring system designed to monitor all aspects of the research carried out one by one,convenience and rapidity giving an example to function can come true by system and what brought about by a user has made and explanation systematically , article theory has described a practical feasible mobile phone satellite fixes position monitoring system truly with a view of actual expounding。The tradition artificial satellite fixer system returns the certain defect and deficiency back to existence , it is believed that with the uninterrupted growth of science and technology and production process of increasing sophistication and mobile phone satellite fixes position monitoring system to make more contributions to the community just around the corner。...
