Description
Technical field
The present invention relates to automatic navigator, relate in particular to a kind of navigating instrument that is provided with the positioning distance measuring device.
Background technology
Continuous development along with onboard navigation system, the peripheral functionality that vehicle mounted guidance relates to and contains is increasing, the for example outer Voice Navigation function that is provided with, function of solar charging, the road memory function, road service system prompting function etc., certainly, the topmost function of navigating instrument still is its navigation function, but along with increasing of automobile, road is crowded all the more, when particularly stopping reversing, though navigating instrument has the reversing prompting function, can not accurately measure and target obstacle between distance, only reliable car steering person observed image in the navigating instrument display screen estimates estimated distance, like this, the driver estimates error and just causes collision easily; In addition, parking lot in some big cities of picture, the parking stall is very limited, the place that can be used to be shifted when going out car and parking is very limited, at this moment, just need know between automobile and the barrier very accurately distance to be used to move car, still, present navigating instrument but can not be clear and definite measures distance between automobile and the barrier.
Summary of the invention
The objective of the invention is deficiency at above-mentioned technical matters, aim to provide the navigating instrument of establishing laser positioning ranging camera head in a kind of, accurately measure distance between automobile and the barrier by the positioning distance measuring device, so that go out car and can accurately measure distance between automobile and the barrier when stopping, make things convenient for the driver accurately to drive.
The present invention is achieved through the following technical solutions: establish the navigating instrument of laser positioning ranging camera head in a kind of, comprise drain pan and the cover of forming housing, the navigating instrument circuit that is arranged at enclosure interior, the display screen that is arranged at cover; The present invention also comprises the positioning distance measuring device, and described positioning distance measuring device comprises the positioning distance measuring crust of the device, is arranged at the camera of positioning distance measuring crust of the device inside, radium-shine laser head, photoelectric sensor, analog-digital converter and central processor CPU; Photoelectric sensor is provided with the photosignal output interface, analog-digital converter is provided with photosignal input interface and digital signal output interface, central processor CPU is provided with digital signal input interface and positioning distance measuring signal output interface, and the navigating instrument circuit is provided with the positioning distance measuring signal input interface; Wherein, the photosignal output interface of described photoelectric sensor is connected with the photosignal input interface signal of described analog-digital converter, the digital signal output interface of described analog-digital converter is connected with the digital signal input interface signal of described central processor CPU, and the positioning distance measuring signal output interface of described central processor CPU is connected with the positioning distance measuring signal input interface signal of described navigating instrument circuit.
Beneficial effect of the present invention is: the radium-shine laser head by the positioning distance measuring device is launched laser to barrier, photoelectric sensor passes to analog-digital converter with photosignal after receiving radium-shine laser head emitted laser bundle, analog-digital converter is converted to digital signal transfers with photosignal and gives central processor CPU, central processor CPU carries out data processing and calculates corresponding position passing to the navigating instrument circuit with the result who calculates corresponding distance and will calculate, thereby the distance between the position that demonstrates barrier on the display screen of navigating instrument and automobile and barrier, the driver can go out car and parking after by the automobile that shows on the display screen and relative position between the barrier and distance accurately.
Fig. 1 is a circuit block diagram of the present invention.
Among the figure: 1, radium-shine laser head; 2, photoelectric sensor; 3, analog-digital converter; 4, central processor CPU; 5, navigating instrument circuit; 6, display screen.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples:
With reference to shown in Figure 1, the navigating instrument of establishing laser positioning ranging camera head in a kind of of the present invention comprises drain pan and the cover of forming housing, the navigating instrument circuit 5 that is arranged at enclosure interior, the display screen 6 that is arranged at cover; The present invention also comprises the positioning distance measuring device, and the positioning distance measuring device comprises the positioning distance measuring crust of the device, is arranged at the camera of positioning distance measuring crust of the device inside, radium-shine laser head 1, photoelectric sensor 2, analog-digital converter 3 and central processor CPU 4; Photoelectric sensor 2 is provided with the photosignal output interface, analog-digital converter 3 is provided with photosignal input interface and digital signal output interface, central processor CPU 4 is provided with digital signal input interface and positioning distance measuring signal output interface, and navigating instrument circuit 5 is provided with the positioning distance measuring signal input interface; Wherein, the photosignal output interface of photoelectric sensor 2 is connected with the photosignal input interface signal of analog-digital converter 3, the digital signal output interface of analog-digital converter 3 is connected with the digital signal input interface signal of central processor CPU 4, and the positioning distance measuring signal output interface of central processor CPU 4 is connected with the positioning distance measuring signal input interface signal of navigating instrument circuit 5.
In concrete the application, radium-shine laser head 1 by the positioning distance measuring device is launched laser to barrier, after photoelectric sensor 2 receives radium-shine laser head 1 emitted laser bundle photosignal is passed to analog-digital converter 3, analog-digital converter 3 is converted to digital signal transfers with photosignal and gives central processor CPU 4, central processor CPU 4 carries out data processing and calculates corresponding position passing to navigating instrument circuit 5 with the result who calculates corresponding distance and will calculate, thereby in position that demonstrates barrier on the display screen 6 of navigating instrument and the distance between automobile and the barrier, the driver can go out car and parking after by the automobile that shows on the display screen and relative position between the barrier and distance accurately.
The announcement of book and instruction according to the above description, those skilled in the art in the invention can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the embodiment that discloses and describe above the present invention is not limited to also should fall in the protection domain of claim of the present invention modifications and changes more of the present invention.In addition, although used some specific terms in this instructions, these terms do not constitute any restriction to the present invention just for convenience of description.
