Abstract
The utility model discloses a vehicle-mounted GPS (Global Positioning System) device. The vehicle-mounted GPS (Global Positioning System) device comprises a shell and an integrated circuit board arranged in the shell, wherein the integrated circuit board consists of an MCU (Microprogrammed Control Unit), the MCU is further connected with a GPS which is further connected with a pre-amplifier and an antenna in sequence; and the MCU is also connected with a storage, a power supply, a keyboard and an LCD (Liquid Crystal Display). The vehicle-mounted GPS device has the advantages of being capable of effectively receiving the signals of the GPS in real time, and conducting navigation in a weak signal place.
Description
Technical field
The utility model relates to a kind of GPS device, relates in particular the vehicle-mounted GPS apparatus of the real-time receive data of a kind of energy.
Background technology
GPS (Global Positioning System), i.e. GPS.In present stage, because gps system has high precision, round-the-clock, high-level efficiency, the characteristics such as multi-functional, easy and simple to handle, GPS has obtained using very widely.
GPS receiver kind is a lot, is divided into geodetic type, full site type, timing type, handheld, integrated-type according to model; Be divided into vehicular, ship borne type, machine-carried type, spaceborne formula, missile-borne formula according to purposes.Wherein vehicle GPS is comprised of controller, GPS and display usually, processes the signal that receives from GPS by controller, is sent to display and shows, to realize the purpose of location.But, being in mountain area or poor signal or unsettled local time when what vehicle GPS was installed, its location will be inaccurate, and the driver has been gone to the wrong way.Especially ought be in mountain area unfamiliar with the place and the people, this location is inaccurate, is not only these troubles of road of taking a wrong way, go for a stroll to what the user brought, sometimes also can bring life danger.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of vehicle-mounted GPS apparatus is provided, and this device can receive gps signal and also can real-time navigation in the place of weak output signal effectively in real time.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
A kind of vehicle-mounted type GPS device, it comprises shell and the surface-mounted integrated circuit that is built in the shell, and described surface-mounted integrated circuit comprises micro-control unit MCU, and described MCU also is connected with GPS, also is connected with prime amplifier and antenna on the described GPS in turn; Described MCU also is connected with respectively storer, power supply, keyboard and liquid crystal display LCD.
Further technical scheme is:
Described GPS is connected by serial ports with MCU.
Described MCU is MSP430 flash series.
Described power acquisition more piece alkaline battery.
MSP430 flash series is 16 single-chip microcomputers, and processing speed is fast, and is low in energy consumption, and volume is little, is adapted at using on the portable instrument.We can select to use Toshiba's antenna antenna, also can custom-made.LCD is used for showing the data such as longitude and latitude, time, height, so that the user knows the understanding of information.Storer is used for the cartographic information of storage Installer Information and download.Power acquisition more piece alkaline battery, replacing easy to use.
Vehicle GPS is comprised of controller, GPS and display usually, but also is connected with prime amplifier and antenna in turn on the GPS of the present utility model.Antenna reception to gps signal be sent to prime amplifier and process amplification, even in the area of weak output signal, also can well bring into play the function of navigator fix.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is stored the electronic chart that receives by storer, the convenient use.
2, be connected with prime amplifier and antenna in turn on the GPS of the present utility model, antenna reception to gps signal be sent to prime amplifier and process amplification, even in the area of weak output signal, also can well bring into play the function of navigator fix.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the circuit modular structure synoptic diagram on the surface-mounted integrated circuit of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.Embodiment of the present utility model includes but not limited to the following example.
[embodiment]
A kind of vehicle-mounted type GPS device as shown in Figure 1, it comprises shell and the surface-mounted integrated circuit that is built in the shell, and surface-mounted integrated circuit comprises micro-control unit MCU, and MCU also is connected with GPS, also is connected with prime amplifier and antenna on the GPS in turn; MCU also is connected with respectively storer, power supply, keyboard and liquid crystal display LCD.GPS is connected by serial ports with MCU.MCU is MSP430 flash series.Power acquisition more piece alkaline battery.
Micro-control unit MCU of the present utility model adopts MSP430 flash series, and we can select to use Toshiba's antenna antenna, also can custom-made.LCD is used for showing the data such as longitude and latitude, time, height.Storer is used for the cartographic information of storage Installer Information and download.Power acquisition more piece alkaline battery, replacing easy to use.Also be connected with prime amplifier and antenna on the GPS in turn.
The course of work of present embodiment is as follows: in use, antenna reception to gps signal be sent to prime amplifier and process amplification, signal after the amplification sends GPS to and processes, information exchange after GPS processes is crossed serial ports and is sent to micro-control unit MCU, and MCU sends to LCD with information again and shows.
According to the above embodiments, can well finish the utility model.
Be as mentioned above embodiment of the present utility model.The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
