For realizing above-mentioned technical purpose, the utility model is achieved through the following technical solutions:

Vehicle mounted guidance terminal device is made up of end device shell and internal circuit.On-vehicle terminal device shell is a rectangular shell, there is human-computer interaction device's touch display screen one side of shell, adjacent side has two antennal interfaces, be respectively BD/GPS antennal interface, GPRS antenna interface, another adjacent side is made up of supply hub, pilot lamp, SD card jack, volume knob, USB interface, earphone jack, power switch.End device shell is built with one piece of main control board, and this main control board comprises S5PV210 micro treatment module circuit, power supervisor modular circuit, BD/GPS modular circuit, SIM900A modular circuit, SD card module circuit, USB module circuit, audio-frequency module circuit, LCD touch display screen module composition.The peripheral circuit of microprocessor module comprises the circuit compositions such as DDR2RAM memory modules circuit, NANDFLASH modular circuit, power filter device, reset circuit, crystal oscillating circuit.

Each model calling relation on main control board: S5PV210 microprocessor chip comprises four UART interface, wherein two serial ports are used for connecting BD/GPS module, GPRS module, the magnitude of voltage that power supervisor module exports different amplitude is supplied to register module pins different in microprocessor, S5PV210 chip is that each module overabsorption goes out corresponding pin interface, therefore SD card module circuit, USB module circuit, audio-frequency module circuit, LCD touch display screen model calling are on corresponding pin.

Principle of work of the present utility model:

The mentality of designing of vehicle mounted guidance terminal device is on the one hand when user wants to obtain the position of oneself, during speed, only need click corresponding icon button by touch-screen, corresponding code can be sent to BD/GPS module by application program, obtaining locator data at that time, is that longitude and latitude is presented on the map of LCD display by processor by data transformations.On the other hand, want to obtain when user's trip and have travel route (shortest time) most, starting point, terminal can be set by touch-screen, end device can be sent to central server by GPRS wireless communication module, optimum travel route is determined according to real-time road condition information and corresponding algorithm by central server, by the mode of wireless communication GPRS module, real-time road condition information and route information are sent to end device, corresponding data can be presented on LCD map by end device, for user provides real-time road condition information and traffic route.Navigation information or locating information also can be passed through voice broadcast out by the audio-frequency module of end device, or provide the voice warning of other functions.End device also can download the renewal of map from server by GPRS.Server is also by the traffic route of GPRS Real-time Obtaining vehicle, and locating information, to Vehicular real time monitoring.

Of the present utility modelly effectively solve vehicle mounted guidance terminal device on Vehicles Collected from Market, map can not be upgraded at any time, real-time road condition information can not be provided, the shortcoming of optimum traffic route is determined according to real-time road condition information, prior big-dipper satellite location, the navigational system being the use of Chinese independent research, safer, reliably, stable.
