With the fast development of computer network, information techniques,digital communications network, and the prevalence of Global Positioning System in recent years,a new kind of product , Vehicles Managing Navigation System,appears.

To improve urban vehicle management level,GPS,GPRS and single chip of C8051F series are used to build a vehicle terminal monitoring system.

The Control System of an Embedded Vehicle Terminal;

Research of GPS vehicle terminal communication technology based on GPRS;

The Design and Realization of Embedded Vehicle Terminal Based on GPS/GPRS;

The vehicle navigation system was constituted by three parts:navigation and control center,vehicular terminal and GPRS communication network.

However, it is hard to collect the data from vehicular terminals on the shuttle buses efficiently, because the present acquisition method depends on manual labor, which is.

Design of distribution transformer monitoring terminal based on DSP and GR 47 wireless module;

A design for the remote monitoring terminal of polluted gas monitoring system based on the ARM and GR47 is proposed.

The design of a repeater monitoring terminal based on ARM and μC/ OS-II is proposed in this paper.
