Principle of work of the present invention:
Because display of the present invention and gun sight have been made incorporate structure, so the code-disc rotating mechanism of gun sight and dampening bracket is fixed together, thus, the operator is rotating by handle in the process of code-disc aiming, tracking, lock motion target, gun sight and display be all corresponding follows rotation, so operator's head and neck certainly will be followed motion together, this has just finished and the real system identical operations, and this point is very important a kind of improvement concerning the training and operation person.
In addition, for strengthening the sense of reality that the observer observes what comes into a driver's and target, adopted virtual reality technology.Computing machine produces three-dimensional what comes into a driver's and target image, and sends it to LCD.In addition, the present invention has solved the problem of ground coupling well, make moving object (tank) under various landforms (hills, meadow etc.) environment, all close proximity to ground motions truly, after the tank motion, its afterbody produces dust and the smog that flies upward, and also can produce various weather environments such as cloudy day, greasy weather, thereby provides sense true to nature extremely strong battlefield training environment for the shooter who observes by gun sight.
Yet in the former scheme of prior art simulation trainer, gun sight is to be located on the supporting disk of dampening bracket, and this coils relative ground and display is fixed, thereby the display in the relative the place ahead of gun sight all is fixed.The operator is by handling orientation and the height handle on the support, driving the rotation data that code-disc in it provides orientation and height passes in the computing machine, motion by what comes into a driver's in Computer Processing and the driving display and moving target, by the what comes into a driver's that moves in the eyepiece observation display of operator by fixed gun sight and moving target rotational orientation and height handle, moving target locks the cross curve center (whole tracking and aiming locking are dynamic change procedures) of gun sight the most at last again.In view of this, be to replace gun sight to move searching for tracking target at this with the motion of what comes into a driver's and target.Can solve the problem of rotating ferret out and the required very big very big display of what comes into a driver's with gun sight like this, and this display also is non-existent.Adopted less display (14～15 cun) for this reason, motion with target and the relative gun sight of what comes into a driver's replaces gun sight to search for extraneous what comes into a driver's and target, and display is motionless, therefore must be rigidly connected between gun sight and the display, to guarantee that the cross center between the two is constant.Again for guaranteeing the suitable field angle and the convenience of certain precision and adjustment, so adopted the adjusting mechanism of six degree of freedom and two fastening steel pole structures, so that easily adjust the exact position between display and gun sight, so it is heavy and complicated that the system that makes seems, but there is not suitable LCD at that time, can not select very big very big display again for use, adopt gun sight to maintain static the scheme of mode, this scheme also should be considered as a kind of rational selection.
The present invention is by the incorporate design of simulation trainer optical aiming system, make simple in structure, the observation visual field is relatively large, and the limb action in the operating process is identical with the manipulation real system, thereby it is little to have solved the field angle that exists in the prior art separate type design proposal, the visual field is unopen, gun sight and guidance dampening bracket relative fixed, operator's head and neck are admittedly easily and what comes into a driver's during training, display separates with gun sight, need the mechanical adjustment mechanism of six degree of freedom, must set up the chassis and be connected variety of issues such as steel pipe, and field angle of the present invention increases 3.5 times, and broad view is taken aim at system's basically identical with real light.Gun sight rotates with dampening bracket, and operator's limb action is identical with the operation real system during training.What comes into a driver's show and gun sight structure-integrated, cancel six degree of freedom mechanical adjustment mechanism, the chassis be connected steel pipe, simple in structure.
