Description of drawings
Fig. 1 is the theory diagram of the utility model searchlight automatic stabilization equipment
Specific embodiments
Function combination principle block diagram 1 with critical piece is described below below:
Searchlight body 1: the searchlight body refers to searchlight itself.Its function is a kind of luminaire.Its brightness, power, volume, bore, weight all can be according to concrete illumination application choices.
Searchlight stable platform 2: searchlight stable platform 2 is carriers that searchlight is installed.This platform can keep angle constant at inertial space after stabilization function is opened.The angle that its points to can be with the swing of carrier (as: boats and ships, vehicle, aircraft etc.), rock, roll, turn to and swing thereupon, rock, roll, turn to, and points to a fixing direction all the time.Because it has at inertial space and keeps isogonal characteristics, so be installed in the object on this platform, also can keep angle constant.If installation material is a searchlight, then can keep the point of irradiation of searchlight constant.
Searchlight lamp body fixed support 3: searchlight body 1 fixedly is connected in link on the searchlight stable platform 2.
Platform horizontal direction control motor and control circuit 5: in order to control the execution unit that platform rotates in the horizontal direction.Control circuit in 5 is accepted the instruction of digital signal processor 11, and the control motor that drives in 5 passes through platform horizontal direction wheelwork 4, drives stable platform 2 and rotates in the horizontal direction.
Platform pitch orientation control motor and control circuit 7: in order to control the execution unit that platform rotates on pitch orientation.Control circuit in 7 is accepted the instruction of digital signal processor 11, and the control motor that drives in 7 passes through platform pitch orientation wheelwork 6, drives stable platform 2 and rotates on pitch orientation.
Platform roll direction control motor and control circuit 9: in order to control the execution unit that platform rotates on the roll direction.Control circuit in 9 is accepted the instruction of digital signal processor 11, and the control motor that drives in 9 passes through platform roll direction wheelwork 8, drives stable platform 2 and rotates on the roll direction.
Level/pitching/roll three-axis gyroscope 10: gyroscope is a kind of surveying instrument of rotational angular velocity.Its function is the angular turn that carrier 12 is installed in impression, and this rotational angular is exported with the form of certain physical quantity (as: voltage) or the form of digital quantity, is fed to digital signal processor 11.The rotation situation that on behalf of carrier, this output carve at this moment.This rotational angular velocity to time integral, just can be obtained the move angle of carrier with respect to the origin-location.This gyroscope also can replace with sensitive three compass.
Digital signal processor 11: be responsible for calculating, data processing and the control of total system.Especially the output signal of gyroscope 10, in 11, carry out filtering, and by digital signal processor 11 calculating, draw the move angle of carrier, then, again to the control motor and the control circuit (5,7 of horizontal direction/pitch orientation/roll direction, 9) send command adapted thereto, with the rotation of control motor.
Before starting this stabilising arrangement, can be with manual mode usefulness hand rotation handle actuating searchlight, searching target more flexibly.This moment, searchlight automatic stabilization equipment of the present utility model were not worked, and searchlight is operated basic identical with common searchlight.But after the searchlight stabilising arrangement starts, do not need this handle can keep stable irradiation substantially to certain objects.Only when needs shine new object, just reuse handle and rotate searchlight.
When searchlight is opened ferret out, use the hand rotation handle to rotate searchlight 1 earlier and seek target as conventional searchlight.When finding target, searchlight 1 is aimed at the mark, open autostable switch (this switch is installed on the manual turning handle handle of searchlight, and is not shown in the figures) then.At this moment, automatic stabilization equipment are started working.Level/pitching/three micromechanics electronic gyroscope of roll (or compass) 10 are started working, and this moment searchlight stable platform 2 position angle, the angle of pitch, roll angle as " zero " direction (that is: initial direction system employing relative coordinate system work).Because control system is started working, the control motor will play the effect of self-locking, the fixedly direction of searchlight under the situation of the work that powers up of no rotation command simultaneously.When carrier 12 shook or swings, three-axis gyroscope 10 was experienced this motion, exported the corresponding voltage signal corresponding to three axial rotation angular velocity respectively.This voltage signal is after digital signal processor 11 reads, and the process integral operation draws the rotational angle on each rotor shaft direction respectively.Digital signal processor 11 to platform horizontal direction control motor and control circuit 5, platform pitch orientation control motor and control circuit 7, platform roll direction control motor and the electric network 9 of control, sends steering order respectively.Platform horizontal direction control motor and control circuit 5, platform pitch orientation control motor and control circuit 7, platform roll direction control motor and control circuit 9, control platform 2 respectively and rotate same angle, thereby guarantee that searchlight keeps transfixion in inertial space to the reverse direction that hull rotates or waves.
Under the guide of this principle, can carry out many kind remodeling to adapt to different requirements.Such as: when searchlight more greatly, when heavier, can in system, increase the power assisting device of hand rotation, make its rotation lighter.When there be needing of remote control in system, can in circuit, increase telepilot.In general, the receiver of telepilot can directly link to each other with digital signal processor 11.Its signal is decoded in digital signal processor, and under the control of control program, relies on the rotation of existing control circuit, control motor, wheelwork control searchlight.Needn't increase a large amount of parts.
Certainly, the stable searchlight of this kind also can be designed to the systems stabilisation (as described in claim 2) of diaxon.Two axle systems can reduce by certain axial parts of cover and Control Software is suitably cut out acquisition by electrical appliance part and the mechanical part to three axle systems.
More than the device of modified autostable searchlight of the present utility model, to those of ordinary skill in the art, all be conspicuous, thereby narration one by one here, all should belong to protection domain of the present utility model in the lump.
