Further, described display screen is a touch LCD screen.
When the utility model used, outside camera was installed in automobile tail usually, so not only has the satellite navigation function, also has the vehicle backing backsight function, and convenient reversing is stopped; Moreover the driver also can observe back car at any time and control following distance by display screen during driving, has improved traffic safety greatly.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the utility model is described in further detail.
See figures.1.and.2, a kind of vehicle mounted guidance and backsight servicing unit comprise main frame, and described main frame comprises:
One satellite navigation module is used for receiving satellite positioning signals and is converted to the bearing data of position;
One memory module is used for storing electronic map data and voice document data;
One central processing unit is used for receiving and handling above-mentioned bearing data, and electronic map data and the voice document data of calling memory module are carried out Navigation Control;
One voice module is connected with central processing unit, and navigation hint and early warning information are used to sound;
One display screen is connected with central processing unit, is used for displayed map and navigation information;
One power module is used to above-mentioned each device that electric power is provided;
Described vehicle mounted guidance and backsight servicing unit also comprise the camera that is installed in the outside, described main frame is provided with the signal receiving module that is used to receive the camera image signal, signal receiving module is connected with central processing unit, and described central processing unit is provided with the mode switch module that is used to switch navigation/image pickup mode.
Described camera is a wireless camera, and described wireless camera is provided with imageing sensor, video processor and wireless launcher, and described signal receiving module is provided with the radio receiver that cooperates with above-mentioned wireless launcher.
Described display screen is a touch LCD screen.
The pixel of described wireless camera is 3,000,000 pixels, and has automatic focusing function, is installed in automobile tail, and the direct image of display automobile back on the display screen is so that the driver can clearly grasp the situation behind the car when moveing backward.The working condition of described wireless camera is as follows: when automobile is moveed backward, the imageing sensor sensing external image of described wireless camera inside also changes into image signal encoding, image signal encoding becomes the analog video signal of corresponding N TSC or pal mode through the video processor treatment conversion, by wireless launcher this analog video signal is sent to signal receiving module in the GPS main frame at last, signal receiving module sends to central processing unit again and handles and export to display screen and show.
Described central processing unit is handled the data that satellite navigation module, signal receiving module, memory module and four modules of voice module send, so that carry out Navigation Control, determining best traffic route, and the analog video signal that will send from signal receiving module converts the picture signal that can show at display screen to by Video Decoder and video processor.
Described memory module links to each other with central processing unit, is used to store electronic map data and the voice document data of calling for central processing unit.Voice document comprises: the prompting of tourist attractions, the overspeed alarm of automobile, fatigue driving prompting, the place ahead have the highway section of camera or velometer to point out or the like the wma file in advance.
Described voice module links to each other with power module, central processing unit, can send a series of promptings such as highway section early warning that direction of traffic prompting, the prompting of tourist attractions, the overspeed alarm of automobile, fatigue driving prompting, the place ahead have camera or velometer.
Described power module is connected with satellite navigation module, central processing unit, voice module and camera, its by corresponding adapter directly and the cigar lighter on the automobile be connected and provide electric power for this device.
Described display screen links to each other with central processing unit and power module, and it is the LCDs of tangible formula, in order to show relevant navigation information, for example: automobile present located position, speed, time, enforcement direction or the like; And the operation that can on display screen, directly be correlated with, for example: the view mode of selecting the GPS navigation map; The planning in path, select the departure place, via ground, avoid ground and destination to determine best traffic route; The distance between calculating departure place and the destination and the time of required cost; The track of driving a vehicle management, so as to consult in the past in the section sometime all places of process; Check near some lodging/food and drink/leisure/amusement/motion/shopping/traffic/information such as finance that current peripheral vehicle is, be convenient to locate fast the needed information that finds.
The above only is an embodiment of the present utility model, rather than be used for limiting practical range of the present utility model, every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, be the utility model claim scope and cover.
