Background technology
Small caliber piece for target be the moving target in space, dynamic tracking precision is the most important technical specification of its fire accuracy. Dynamic tracking precision is exactly that armament systems aiming line points to target, and the Artillery rifle of actual transmission bullet (firepower line) points to and put future and the error size of expectation point in future. At present only by zero, the detection of dynamic tracking precision is flown instrument to realize. Zero to fly instrument be supposing that projectile time of flight is zero, and gun bore line points to dynamic tracking precision when not having an advance angle. As can be seen here, zero to fly that instrument only detects be do not have the dynamic tracking precision under a kind of specified conditions of fire control system advance angle, can not completely test the dynamic tracking precision of armament systems. No matter range acceptance cannon or army's preshot systems inspection, all need a kind of device realizing complete dynamic tracking precision badly.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Elaborate a lot of detail in the following description so that fully understanding the present invention, but the present invention can also adopt other to be different from alternate manner described here to be implemented, those skilled in the art can do similar popularization when without prejudice to intension of the present invention, and therefore the present invention is not by the restriction of following public specific embodiment.
As shown in Figure 1, the invention discloses a kind of small caliber piece dynamic tracking accuracy detecting device, described detecting device includes thorax Self-centering device, power module and human-computer interaction module in processor, marking apparatus, the high-precision photographic head of rifling, the high-precision photographic head of fire control, barrel.The high-precision photographic head of described marking apparatus, rifling and the high-precision photographic head of fire control are connected with the signal input part of described processor, and marking apparatus is for measuring small caliber piece aiming line and the Artillery rifle differential seat angle in orientation with firing angle both direction; The high-precision photographic head of described rifling is arranged on Artillery rifle place by thorax Self-centering device in described barrel, and the high-precision photographic head of rifling points to the spatial image obtained for real time record Pipe rifling; The high-precision photographic head of described fire control is for recording the spatial image that fire control system aiming line points to; Described power module is connected with the power input of the module needing power supply in described detecting device.
As in figure 2 it is shown, described marking apparatus includes four demarcation bars 1, described demarcation bar 1 is arranged in described gun barrel 2 around uniformly, and described demarcation bar 1 is respectively provided with orientation and firing angle range marker. Described human-computer interaction module and described processor bidirectional data communication, for inputting data and video data, described human-computer interaction module has two kinds of selections, the first is touch screen, and the second is the key-press module that the signal input part with processor is connected and the display module being connected with the signal output part of processor. In order to realize storage and the transfer of data easily, described detecting device also includes interface module, described interface module and processor bidirectional data communication, is used for realizing this detecting device and is connected with ancillary equipment.
Gun fire control system gives the corresponding orientation of gun barrel and firing angle lead according to certain air route, namely expects lead; And owing to fire control system control servo system drives the orientation that mechanical mechanism makes barrel be actually pointed to necessarily to have error with firing angle and expectation lead, this difference is dynamic tracking error. Detecting device is obtained by photographic head the space diagram aberration of fire control and barrel, is converted to fire control system and barrel angle difference spatially according to marking apparatus, including orientation and firing angle both direction. This difference and the fire control system difference of calculated desirable lead (this lead can be obtained by calculating, it is also possible to is directly read by cannon bus system) on certain air route is the cannon dynamic tracking error that actual test obtains.
Operation principle: as shown in Figure 3, rifling high accuracy photographic head is arranged on the rifling place of gun barrel by described detecting device by thorax Self-centering device in barrel, point to the spatial image obtained for real time record Pipe rifling, fire control high accuracy photographic head is used for recording the pointing space image of fire control system (aiming line); The pointing space image of fire control high accuracy photographic head pointing space image and rifling high accuracy photographic head is input simultaneously in processor, the processor difference according to two image spaces, and the aiming line that collects of the marking apparatus pre-set and the firepower line differential seat angle in orientation Yu firing angle both direction, in conjunction with the calculated expectation advance angle of fire control system (including orientation and two angles of firing angle), the dynamic tracking error value of cannon can be obtained.
Described detecting device utilizes the technology such as images match measuring principle, computer picture recognition and self calibration to realize, have digitized, all automatic measurement, self calibration, in high precision, spatial dimension measure the feature such as accurate. As required, set projectile time of flight as zero time, zero can be realized and fly instrument test, and extend to the dynamic tracking accuracy test of other large caliber gun, rocket gun, the blank of the means of dynamic tracking accuracy detection can be filled up, it is effectively improved measuring accuracy and testing efficiency, reduces labor intensity and the technology requirement of operator.
