Summary of the invention
Be to solve the defects that prior art exists, the purpose of this utility model is to provide that a kind of efficient is high, speed is fast, simple to operation, adapts to motorization and fast helicopter landed the boresight system of free attitude boresight.
The technical solution adopted in the utility model: this helicopter lands free attitude boresight system, comprise target plate and main frame, it is characterized in that: described main frame is connected with bore sight, laser range finder and inclinator, described inclinator is placed on the levelling bench of helicopter, the sensor of inclinator adopts stationary structure to be fixed on helicopter inside, inserts on Host Status measurement socket by air plug and is connected into main frame; Described bore sight is made of ccd video camera and the corrective lens (eye protection) that is positioned at before ccd video camera, described ccd video camera and corrective lens (eye protection) are connected on inserted link after being connected by flange, inserted link can directly insert the outside hanger of helicopter, and the ccd video camera video outputs to main frame by connecting line; Described laser range finder is made of peephole and Laser emission receiver, described peephole is parallel with the diaxon of Laser emission receiver, the Laser emission receiver directly inserts the outside hanger of helicopter by inserted link, described Laser emission receiver connects the switching mechanism that can regulate the laser range finder pitching, find fast target plate, described peephole is connected with form by photoelectric switching circuit, range finding numerical value can be shown direct reading by form.
Described corrective lens (eye protection) is two cemented objectives.
The laser beam of described Laser emission receiver is all 635nm.
The utility model principle:
1, set up body axis system: in this programme, all the time use body axis system in the boresight process, and do not use earth axes, when guaranteeing that helicopter is in free position, still can pass out body axis system with the method, thereby save the body gentle bracing wire in top the work of body axis system and earth axes leveling row, shorten the boresight time, increase work efficiency.
Adopt flat aobvious center as the origin of coordinates of body axis system, recomputate the weapon coordinate in the position of new coordinate system and be kept in boresight system storage chip.During boresight, to put down aobvious center " ten " word line (being also the body coordinate) aligns with target plate " ten " word line, be equivalent to set up body axis system on target plate, when helicopter is in original position (not pushing up flat) state, state by survey aircraft and being input in the boresight system is revised coordinate figure, it has just transmitted body axis system, so " ten " word line on target plate just can be used for carrying out boresight.
2, calibrator mechanism: the position that theoretical boresight point is helicopter central axis relative to weapon is that body axis system is determined, has set up the coordinate system transformational relation of body axis system with flat aobvious center by above-mentioned 1.Therefore on 1 basis, calculate the coordinate that each desirable boresight point at flat aobvious centre coordinate is, and be stored in bore sight, automatically generate corresponding aiming " ten " word line by bore sight during boresight, and show on display.During aiming, observe aiming " ten " word line and whether overlap with the picture of target plate " ten " word line on the display screen of bore sight, do not need to carry out the boresight operation if do not overlap.
Adopt the beneficial effect of technique scheme: this helicopter lands free attitude boresight Systems Theory boresight point, the position that is helicopter central axis relative to weapon is that body axis system is determined, by the coordinate system transformational relation of body axis system with flat aobvious center, calculate the coordinate that each desirable boresight point at flat aobvious centre coordinate is, and be stored in bore sight, automatically generate corresponding aiming " ten " word line by bore sight during boresight, and show on display.During aiming, observe aiming " ten " word line and whether overlap with the picture of target plate " ten " word line on the display screen of bore sight, do not need to carry out the boresight operation if do not overlap.
The levelling bench of helicopter is detection reference important in the boresight process, in the boresight process, obtains the state index of helicopter by placing spirit level on levelling bench, is up to the standard by the pitching of three hydraulic jack adjustment helicopters, roll both direction.The sensor of inclinator is fixed to helicopter inside, disposable in the time of only need to dispatching from the factory sensor is proofreaied and correct, just can eliminate operator's observation error and put error in the boresight process, do not need sensor is proofreaied and correct before the helicopter overhaul, concerning whole boresight system, fixation of sensor can provide quick, light, a reliable test environment.This boresight system can utilize laser accurately to measure weapon to the distance of target plate, can check the uniformity of mechanical axis, TV axle, the graduation of electricity " ten " word, can measure roll angle and the angle of pitch of helicopter.Compared with prior art, boresight is convenient, and efficient is high, adapts to motorization and tackles fast requirement.
Calculate by Coordinate Conversion, automatically generate with former boresight on display and put aiming point one to one, solved the problem that needs the picture target plate before the boresight.
Adopt flat aobvious center as the boresight benchmark, solved the levelling bench error and caused too greatly the skimble-scamble situation of every airplane coordinate, solved the coordinate system problem of transmission of TV boresight system, avoided the operation of the flat helicopter of boresight sinciput.
Adopt the mode of manual switching to select type, weapon type etc., easy to operate, quick, each operation only shows a kind of aiming point of weapon, the phenomenon of easily having made mistakes when having avoided showing a plurality of aiming point simultaneously on the target plate.
Adopt CCD to aim at, carry out error judgment by display, intuitive is good, convenient operation.
Adopt the helicopter attitude measurement mechanism to detect helicopter attitude, and can directly revise as the calculated data input system, guaranteed the boresight precision.
Adopt laser ranging, need not manually measure, and guarantee certainty of measurement, improved boresight efficient and precision.
