Abstract
The utility model discloses a marine navigator adopts the module to connect, include: the system comprises a GPS receiving module, a key module, a program and chart storage module, a video processing module, a central processing unit, a random access memory and a display. The marine navigator adopting the structure is convenient to operate, easy to master using method, low in cost, and capable of displaying the chart which is clear at a glance by sailing personnel or common personnel, and providing safe, reliable, accurate and clear navigation related geographic information for the sailing personnel.
Description
Affiliated technical field
The utility model relates to a kind of positioning and directing navigator, the navigating instrument that especially a kind of ship's navigation positioning and directing again can displayed image.
Background technology
Along with development of science and technology, GPS (GPS) is widely used in the navigation and the location of aviation, navigation, land carrying tool, especially Xian Dai technology, the function of electronic chart and GPS (GPS), radar, computing machine is combined, for the navigation personnel particularly the oceangoing voyage personnel safer, accurate, clear, the sea chart that navigates reliably is provided, thereby reach accurate in locating, constant-bearing navigation.But because present technology can't provide so a kind of is convenient to operation, using method grasps easily, cost is low, can show the navigating instrument peculiar to vessel of the sea chart that navigation personnel or ordinary person understand at a glance again.
Summary of the invention
The utility model purpose is to provide a kind of operation of being convenient to, and cost is low again, and using method is grasped easily, can show the navigating instrument peculiar to vessel of the sea chart that navigation personnel or ordinary person understand at a glance again.
For achieving the above object, according to the technical solution adopted in the utility model, provide a kind of navigating instrument peculiar to vessel, adopt module to connect, comprise: GPS receiver module, key-press module, program and sea chart memory module, video processing module, central processing unit, random access memory, display.Central processing unit by serial line interface respectively with program and sea chart memory module, the GPS receiver module links to each other with key-press module, links to each other with video processing module with random access memory by parallel interface, video processing module links to each other with colour liquid crystal display device.
Central processing unit obtains program command signal by quick fetch program of serial line interface and sea chart memory module, then read institute's canned data in the random access memory by parallel interface, resolve,, send instruction respectively and read GPS receiver module data message then according to analysis result; Send instruction to program and sea chart memory module, extract needed nautical chart information according to the information of from random access memory, reading; Send instruction and realize the Color Liquid Crystal Display function to the video processing module requirement.After each module is received the instruction of central processing unit, realize its function, and result is returned to central processing unit.Central processing unit extracts some important informations according to the result of receiving, as the concrete data behind the GPS location, the information that key-press module transmits etc.Resolve by inner then, send instruction to each module section again again, obtain new sea chart,, show needed information frame about positioning and directing according to the instruction of key-press module.Repeat work so always, refresh sea chart at any time, again can be with the information stores that is presented at display finished at every turn in random access memory, for reading.
The beneficial effects of the utility model are: the navigating instrument peculiar to vessel that adopts this structure, be convenient to operation, using method grasps easily, cost is low again, can show the sea chart that navigation personnel or ordinary person understand at a glance again, for the navigation personnel provide navigation safe, accurate, clear, reliable positioning and directing relevant geography information.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a theory diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model adopts module to connect, and comprising: GPS receiver module (1), key-press module (2), program and sea chart memory module (3), video processing module (4), central processing unit (5), random access memory (6), display (7).
Central processing unit (5) by serial line interface respectively with program and sea chart memory module (3), GPS receiver module (1) links to each other with key-press module (2), link to each other with video processing module (4) with random access memory (6) by parallel interface, video processing module (4) links to each other with colour liquid crystal display device (7).
Generally speaking, central processing unit (5) is by the serial line interface information of fetch program and sea chart memory module (3) fast, with read institute's canned data in the random access memory (6) fast by parallel interface, and resolve, according to analysis result, send instruction respectively and read GPS receiver module (1) data message, and the information feedback of location is returned; Central processing unit (5) is according to the result of receiving, extract some important informations, as the concrete data behind the GPS location about positioning and directing, the information of quick then fetch program and sea chart memory module (3), and resolve, at last analysis result is delivered to video processing module (4), in the position of the sea chart at self ship point place of display (7) display requirement location through, latitude, and the information frames such as speed, direction and arrival destination distance that navigate by water of ship.On the other hand, can be according to the key-press module command request, central processing unit (5) can change into GPS receiver module (1) data message the graphic form that navigation personnel or ordinary person understand at a glance, carries out information stores by parallel interface and random access memory (6).
Central processing unit (5) can repeat to send instruction to each module section, obtains new sea chart, according to the instruction of key-press module (2), shows needed picture.Repeat work always, refresh sea chart at any time, again can be with the information stores that is presented at display (7) finished at every turn in random access memory, for reading.
Adopt the navigating instrument peculiar to vessel of this structure, be convenient to operation, using method grasps easily, cost is low again, can show the sea chart that navigation personnel or ordinary person understand at a glance again, for the navigation personnel provide safety, reliably, accurately, the relevant geography information of the navigation of positioning and directing clearly.
Claims (2)
1, a kind of navigating instrument peculiar to vessel adopts module to connect, and it is characterized in that: comprise the GPS receiver module, key-press module, program and sea chart memory module, video processing module, central processing unit, random access memory, display; Central processing unit by serial line interface respectively with program and sea chart memory module, the GPS receiver module links to each other with key-press module, links to each other with video processing module with random access memory by parallel interface, video processing module links to each other with display.
2, a kind of navigating instrument peculiar to vessel according to claim 1, it is characterized in that: central processing unit links to each other with program and sea chart memory module by serial line interface, read its program stored and nautical chart information, can carry out information stores by parallel interface and random access memory again.
