The vehicle-mounted navigating instrument has high positioning accuracy.

Description

Automatic navigator based on dipper system

Technical field

The utility model relates to a kind of automatic navigator, particularly a kind of automatic navigator based on dipper system.

Background technology

Existing automatic navigator all is based on the GPS of USA system.

GPS (Global Positioning Systems) is that the U.S. went through 20 years, and the expensive Global Positioning System (GPS) that surpasses 30,000,000,000 dollars of foundation is the 3rd huge space programme after Apollo Moon-landing Project and space shuttle plan.Its target fundamentally solves human navigation and orientation problem on earth, to satisfy the needs of various different users for three-dimensional position, three-dimensional velocity and high precision time information are provided in real time.

The main part of gps system is made up of 24 geostationary satellites, and these satellites and ground supports system form network, with the positional information to global broadcast oneself.For the user; Most important is exactly the GPS receiver, and receiver is used the difference positioning principle according to the positional information of the 4-8 that receives a simultaneously satellite; Every separated 1-3 reports once its position (longitude and latitude), speed, height and temporal information to the user second, for system's use of user or user.

Though it is GPS is widespread use, also flawless absolutely not.For example, its scale is too big, cost is too high, and other countries are difficult to imitate; GPS can only navigate, and can't communicate by letter, thereby can not satisfy growing user's request; If only rely on GPS, then controlled by the U.S..

The utility model content

The utility model purpose: to the problem and shortage that above-mentioned prior art exists, the purpose of the utility model provides a kind of automatic navigator based on dipper system that improves bearing accuracy.

Technical scheme: for realizing above-mentioned utility model purpose; The technical scheme that the utility model adopts is a kind of automatic navigator based on dipper system; Comprise microprocessor, the two navigation modules of the Big Dipper/GPS, gyro module, wireless communication module and display device, said microprocessor connects the two navigation modules of the Big Dipper/GPS, gyro module, wireless communication module and display device respectively.

Also can comprise the amusement sound system that connects said microprocessor, the CMMB television module that connects said microprocessor and the reverse image module that connects said microprocessor.

The preferred WIFI communication module of said wireless communication module.

Beneficial effect: triones navigation system can round-the-clock quick location, few communication blind district, and precision and GPS are suitable, and in the enhancement region Asian-Pacific area just, can surpass GPS; The service that provides to the whole world all is free, and when providing passive location navigation and time service etc. to serve, number of users is restriction not, and compatible with GPS; Be particularly suitable for group user large-range monitoring and management, and do not have the area data of support and gather the user data transmission application; Unique centromere point type localization process and the design of commander's type subscriber computer, can solve " at which am I? " simultaneously " at which are you? " The high strength encrypting design, safety, reliable, stable is fit to key sector and uses.The utility model has combined the dual-satellite system navigation of the Big Dipper and GPS, utilizes inertia and radio communication to assist again, makes that the signal of navigation is highly stable, though satellite-signal blind areas such as entering tunnel, the location navigation that also can continue.Also provide a cover high-quality sound shadow service system, make the passenger obtain high-quality seeing and hearing enjoyment.

Description of drawings

Fig. 1 is the module frame chart of the utility model based on the automatic navigator of dipper system.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.

As shown in Figure 1, the utility model comprises with lower module based on the automatic navigator of dipper system:

The two navigation modules of the Big Dipper/GPS: be used for satnav, can between the Big Dipper and GPS, switch fast, to find best positioning signal.

Gyro module and WIFI communication module: when car gets into the location of tunnel or other no satellite-signal coverings; Position through the WIFI wireless network; And inertia algorithm in conjunction with gyroscope (being the gyro module); Come the short time to carry out seamless access location, waited satellite-signal, then switch to satnav immediately.

Colorful display screen: high-quality graphical interfaces is provided, shows current position (longitude and latitude), speed, height and temporal information etc.

Amusement sound system:, make the passenger obtain high-quality seeing and hearing enjoyment through amusement sound systems such as radio, DVD are provided.

CMMB (China Mobile Multimedia Broadcasting, China Mobile multimedia broadcasting) module: digital television service is provided, makes the passenger can watch the program in tens radio station onboard.

Reverse image module: connect reversing camera (not shown), the reversing video information is provided.

CPU module: adopt ARM CORTEX-A8 nuclear as processor, perfect video, communication solution are provided.
