Description
Technical field
The present invention relates to a kind of electronic bearing instrument apparatus and its using method, it belongs to the application of Navigation in Ship.
Background technology
At present, the method for implementation goal azimuthal measurement is applied in combination come real by azimuth device and bearing repeater on naval vessels
Existing.Azimuth device is the necessary component that gyro compass is equipped with naval vessels, and installed in the bridge outside left and right sides and broad view
Bearing repeater be applied in combination, for observed object orientation.The short axle of azimuth device bottom is inserted into repeater compass glass when using
After in the axis hole of lid, azimuth device can be freely movable about the center rotating of compass scale.Line pair is concentrated one's gaze on when what eyepiece object lens were constituted
During quasi- target, orientation reading can read in eyepiece, and side of a ship angle reading is read by the index below eyepiece from angle on the bow graduated ring.
What is be generally equipped with naval vessels at present is HGF -239 type optical azimuth devices, as shown in Figure 1.The optical azimuth device is consolidated
Dingan County is loaded on the solid gimbals of warship bow, including：Eyepiece focal length adjuster, to the definition for adjusting target；Azimuth scale is put
Big lens actuator, to make clear reading；Optical filtering is adjusted（Conversion）Device, from the suitable optical filtering of color, to make light
Strong objective contour understands and not dazzling eyeball；Speculum, to the target for observing the high elevation angle；Spirit bubble, during interception so as to
Keep azimuth device level；Outline concentrates one's gaze on device, concentrates one's gaze on target to first outline and is accurately observed with telescope again.When using, using people
By naked-eye observation eyepiece, adjustment optical azimuth device alignment observed object, read by azimuth scale magnifying glass above deck at member station
The orientation reading taken on dial determines target bearing.
Digital Bearing Compass (HSF-001) in also a kind of use, the observed result during azimuth device run-home is not
Dial reading is read, but directly reads display screen orientation digital quantity, in the moment of run-home lockable target bearing is gone back
Show value.The generation of target angle：Fixed circle is connected with naval vessels fore and aft line, and zero-bit direction is parallel with naval vessels fore and aft line, moving-coil and prestige
Remote mirror is connected, and when such telescope turns to target, angle on the bow generator will be driven to rotate, and forms angle on the bow α and shows.HSF-001 numbers
Word azimuth device differs primarily in that with HGF-239 optical azimuth devices, further comprises angle on the bow generator, computing module and display
Screen, during measurement target bearing, angle on the bow generator is driven when telescope objective is rotated, and produces the digital angle on the bow that precision is 0.05 °
The course signal of input is added and obtains target bearing signal, azimuth by signal to computing module, computing module with side of a ship angle signal
Shown in display screen with digital quantity, so that observer reads at any time azimuth of target.
Traditional azimuth device has in actual use three below limitation：One is to need manually to be grasped above deck
Make, higher to the observation level requirement of user, it is larger to align measured target difficulty in the case of warship swing, particularly exists
Under the mal-conditions such as heavy rain, cold, personnel are difficult to effectively measure target bearing out of my cabin；Two be to measurement accuracy without
Method determines that, because target bearing is the numerical value that the moment overlapped in optical azimuth device and target reads, correctness cannot be investigated；
Three is the requirement that can not meet naval equipment modernization, and " wholly closed vessel ", " stealthy naval vessels " are the development sides of my naval ship
To this means that the personnel activity that reduce on-deck equipment and on-deck as far as possible.

It is erected on high accuracy head, realizes 360 degree of rotations of high-definition camera, and then realize that naval vessels outboard panorama is observed, video is adopted
Truck one end other end that is connected with high-definition camera is connected with information solving unit, the video in real time gathering high-definition camera
Image is decoded, and by observed object signal information solving unit is given；Device control cell is by cradle head control module and corner
Module composition is resolved, is connected with head and information solving unit, the rotation instruction that one side receive information solving unit comes, control
The rotation of head processed, the angle on the other hand then rotating head realizes digitlization, and is transferred to information solving unit；Information solution
Calculating unit includes that course resolves module, video display module, SCM system, input through keyboard module, digital display module and electricity
Source module, is connected with video frequency collection card, device control cell, while be also connected with naval vessel gyro compass, according to from the video
Observed object signal and the head angular signal from device control cell reception that collecting unit is received, with reference to from naval vessel electricity
The course signal that compass is received, calculates the bearing signal of target being observed, and gives display and show, while over the display
The vision signal of Small object is shown, makes human pilot clearly check closely Small object.
The using method of described electronic bearing instrument：Search of the high-definition camera realization to naval vessels outboard observed object, one
Denier locks observed object, then the angle that head is turned over is exactly the angle on the bow of target；Electronic bearing instrument is given after angle on the bow is digitized
Orientation resolving center；Gyro compass on naval vessel provides in real time current course information, wherein all the way course information is through numeral
The orientation resolving center of electronic bearing instrument is given after change；Electronics resolves Central Radical according to target angle information and current heading device
Breath, according to relation then between true course, true bearing and angle on the bow the real-time azimuthal letter of observed object just can be in real time calculated
Breath.
