Abstract
The utility model relates to a monitoring control system, in particular to an intelligent navigation system for a ship during navigating. The utility model discloses a radar navigation system with reference to an electronic map, comprising a navigating radar, a radar data receiving unit and a data verifying unit for verifying the received radar data, and further comprising an analog-to-digital conversion unit, an optical grating scanning unit, an image overlaying and comparing unit and an image output unit, which are sequentially connected with each other, wherein the analog-to-digital conversion unit is used for converting the verified radar data into digital signals, the optical grating scanning unit is used for scanning the digital signals by means of optical grating to obtain an optical grating scanning video image, the image overlaying and comparing unit is used for overlaying and comparing the optical grating scanning video image with the electronic map, and the image output unit is used for outputting the overlaid image. The radar navigation system with reference to the electronic map is used for overlaying and comparing the acquired video signal with the electronic map, so that the navigation is more intuitional and reliable.
Description
Technical field
The utility model relates to a kind of monitor control system, relates in particular to a kind of ship's navigation navigational system.
Background technology
Marine navigation radar is mainly used to find and measure the direction and the distance of target on every side, correctly shows water front, navigation mark, other navigating ships or other marks coordinate position with respect to radar, so that this ship is taked correct navigation attitude.
At present basically in, large-scale civilian ship and military naval vessel all be equipped with navar, playing sizable effect aspect the navigation of ship, the collision prevention.But, the vision signal of radar collection does not comprise the sea chart essential information, water front for example, and buoys etc. cause navigation directly perceived inadequately.
Summary of the invention
Exist the vision signal of radar collection not comprise the sea chart essential information at prior art, cause navigation defective intuitively inadequately, the utility model provides the radar navigator of the contrast electronic chart that a kind of vision signal that radar is gathered and electronic chart stack contrast.
For achieving the above object, the utility model adopts following technical scheme:
The radar navigator of contrast electronic chart, comprise navar, the radar data receiving element, the radar data that receives is carried out the data check unit of verification, also comprise the AD conversion unit that connects successively, the raster scanning unit, image overlay contrast unit, the image output unit, described AD conversion unit is used for converting the radar data after the verification to digital signal, the raster scanning unit is used for that digital signal is carried out raster scanning and obtains the raster scanning video image, image overlay contrast unit is used for the contrast that superposes of raster scanning video image and electronic chart, and the image output unit is used for the image after superposeing is exported.Because electronic Chart Display is digital quantity, and be to show at plane right-angle coordinate, and radar signal is to measure in the two-dimentional polar coordinate system, measuring the signal that comes is position angle and distance, major part is an analog quantity, so will convert analog quantity to digital quantity, by the raster scanning unit polar coordinate transform is become planimetric rectangular coordinates, so that superpose contrast by AD conversion unit.
As preferably, the radar navigator of contrast electronic chart also comprises the amplification denoising unit that the radar data signal after the verification is carried out denoising and image enhancement processing, and described amplification denoising unit is connected between data check unit and the AD conversion unit.Undertaken carrying out analog to digital conversion again after denoising and the image enhancement processing by amplifying the radar signal of denoising unit after with verification, precision is higher.
Vision signal and electronic chart stack contrast that the radar navigator of contrast electronic chart of the present utility model is gathered radar make navigation directly perceived more, reliable.
Description of drawings
Fig. 1 is the structural representation of embodiment.
Embodiment
Below in conjunction with Fig. 1 and embodiment the utility model is described further.
The radar navigator of contrast electronic chart, as shown in Figure 1, comprise navar 1, radar data receiving element 2, the radar data that receives is carried out the data check unit 3 of verification, also comprise the amplification denoising unit 8 that connects successively, AD conversion unit 4, raster scanning unit 5, image overlay contrast unit 6, image output unit 7.
Whether the radar signal data that navar 1 is gathered belong to the required radar signal of this ship from 2 receptions of radar data receiving element and by data check unit 3 with check, through verification is the words of the data-signal of needs, by amplifying denoising unit 8 this radar data signal is carried out denoising and image enhancement processing, convert the radar data after denoising and the image enhancement processing to digital signal by AD conversion unit 4, raster scanning unit 5 carries out raster scanning with digital signal and obtains the raster scanning video image, image overlay contrast unit 6 is with the contrast that superposes of raster scanning video image and electronic chart, and the image after image output unit 7 will superpose is exported.
By the utility model, the image information of navigation and electronic chart can be superimposed and compare, and the navigation personnel are directly perceived more, convenient, reliable to the judgement of position.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model, and all equivalences of doing according to the content of the application's claim change and modify, and all should be technology category of the present utility model.
