Design And Implementation Of Positioning System Based On Baidu Maps And Embedded System

How to scientifically implement the supervision to prevent government agencies use government cars for private purpose, becomes a problem in vehicle management department. In response to these needs, this paper by GPS technology, data communication technology, network technology, embedded systems into the Internet with Baidu maps proposed.vehicle location monitoring system based on B/S mode, can solve the above problems.The paper first analyzes the domestic and international research status, researches the key technology of vehicle monitoring system, the monitoring system consists of three sub modules:vehicle terminal, the monitoring center server and monitor terminal.The vehicle terminal is mounted on the vehicle. The design is divided into two parts of software and hardware. Hardware circuit needs to considerate the system requirement and cost, which describes the design process of selecting modules and modules peripheral circuits. Software design according to the system requirements, completed the design of extraction, caching the positioning information, control GPRS module TCP, transmit positioning data.The monitoring center server is the core of the system, using JAVA language which has a good transplant. Completed the main page design of the monitor center, to receive the minimum positioning data storage and update to the MySQL database. Through the multi thread technology to solve the multiple clients accessing the server at the same time, to request authentication and access location information. Read the data in the database and finally generate the Baidu map API standard JSP code, returned to the requesting user PC.The monitoring terminal is the PC which connected to the Internet. The system is based on B/S structure. through the PC browser access to the monitoring center server may be regarded as the monitoring client authentication, parsing JSP code returned by the server.
