Back-end Service Software Design Of Vehicle Positioning System For Special Cars

The back-end service software of vehicle positioning system for special cars,cooperating with electronical maps,may have a visible real-time monitoring and status monitoring on vehicle terminals through positioning information of vehicle terminals passed back by communication technology.The back-end service software system,as a crucial part of police tracing work,has a function of receiving,searching and displaying of monitoring information,provides convenience for administrators to make operation and management of vehicle terminals,helps the police force to coordinate and make reasonable arrangements for their special work plan,and improve the accuracy and reliability.The development and application of the back-end software not only has a great significance in enhancing regulation of the police force,but also provides much help in command and control of major security work.This article has a research on the vehicle positioning system for special cars and mainly discusses the design and realization of the back-end service software system.By a analysis of requirement from the perspective of function,performance and data,it develops a overall design scheme of the system,in which the core technology of the back-end service software system may be ascribed to GIS,website and database application technology.The system,adopting C/S structure,has a secondary development by using C#.Under the structure of C/S,the back-end database makes its design and realization by Access database software.The logic of business module is the hinge of the software system.This article which discusses from the two aspects of function module and data processing module,described in detail the design principle and method of realization of the electronical fence,terminal management and log management.At last,it verifies correctness and flexibility of the back-end service software system by function tests and performance tests.The test result indicates that the back-end service software,implemented by this article of the vehicle positioning system reaches the expected goal of design and has a higher value in application.
