Abstract
The invention discloses an indoor calibration method for optical sights. Optical reference debugging, product pitch zero-position debugging and product azimuth debugging are realized by a calibration system so that indoor calibration of the optical sights is realized. By the indoor calibration method for the optical sights, the problems that in the prior art, zero setting operation is carried out after equipment is butted with a launcher in the outer field, a transmitter is regulated on the basis of a receiver, and then error of the receiver is introduced, so that display precision is reduced, and pointing error is increased, namely zero positions of the optical sights are incapable of being tested due to absence of the zero-position reference are solved.
Description
Technical field
A kind of optical sighting device Calibration Method, particularly a kind of indoor calibration method for optical sights.
Background technology
Optical sighting device is a kind of manual visual tracker, is used for that radar is disturbed or lose objects replaces intercepting and capturing unit the target indication is provided.After past, the optical sighting device telescope was debug, whether mechanical zero and electrical equipment zero point consistent was unknown, there is no the absolute zero position of equipment, must to outfield with carry out zeroing work after the car launcher radar docks.Find relative zero-bit synchronously to guide work.Before batch producing, every complete equipment need arrive outfield and docks with car launcher, and employing amplitude limiter circuit, impedance inverter circuit are with synchro-transmitter error signal and synchro-receiver error signal process phase-sensitive rectifier circuit, signal transformer, demodulation output display.The receiver of using is like this transferred transmitter as benchmark, and the error band of receiver is come in, and makes display precision reduce.Vectoring error increases.Actual is that zero reference does not exist, and can't test light take aim at zero-bit.And condition of external field is poor, debug difficulties, and the equipment that quantity is few can adopt the outfield synchronous debugging, and batch products adopts this mode just unrealistic later.And with batch products zero-bit precision consistance, interchangeability, can't guarantee.File (CN1727864A20060201) discloses a kind of static angular pick-up unit of portable optical observation sighting instrument, the instrument and equipments such as optical measurement all purpose instrument parallel light tube wherein, transit are to carry out light to take aim at the necessary instrument and equipment of measurement of angle equally, but use can't be carried out the calibration debugging that light is taken aim at zero reference separately.
Summary of the invention
The object of the invention is to provide a kind of indoor calibration method for optical sights, and the zero reference that calibration light is taken aim at solves optical sighting device batch production outfield debug difficulties later, homogeneity of product, the poor problem of interchangeability
A kind of concrete steps of indoor calibration method for optical sights are:
The first step is built Calibration System
Calibration System comprises: selsyn zeroing combination (certainly grinding), three-phase mid-frequency inverter, test cable, center test bracket, test bracket A, test bracket B, test bracket C, dome, cylinder, vertical and optical measurement all purpose instrument: parallel light tube A, parallel light tube B, parallel light tube C, transit.
Test bracket A, test bracket B, test bracket C and test bracket position, center line are mutually 90 ° of directions and place, and parallel light tube A, parallel light tube B, parallel light tube C are placed in respectively on corresponding test bracket and are screwed; Dome, on the cover plate of cylinder centering test bracket; Vertical is connected with the transit bottom thread; Selsyn zeroing combination is connected with test cable with the three-phase mid-frequency inverter.
Second step debugging optical reference
Centered by the test bracket of center, Yi Bian peripheral test bracket A, test bracket B, the test bracket C of placing, and range estimation guarantees that test bracket A, test bracket B, test bracket C and test bracket position, center line are mutually 90 ° of directions and place.Then with above the cylinder of installing on transit centering support, the transit bottom self-control plummet of screwing on.Again three parallel light tubes are placed in respectively on the cover plate of the test bracket A, the test bracket B that are mutually 90 ° of positions, test bracket C.Adjust the transit level, transfer the transit bubble and close to resemble and all occupy its center separately, respectively three parallel light tubes are carried out angle and horizontal reading take transit as benchmark and measure, make three parallel light tubes be mutually 90 ° and be in same level after adjusting.Like this, parallel light tube just can be used as optical reference that test light is taken aim at.
The debugging of the 3rd step product pitching zero-bit
On the test bracket of center, transit, cylinder, dome are unloaded, change the light that is unkitted binocular telescope and take aim at mechanism.The fine setting test bracket makes the round bubble that light is taken a fancy to be in center.Then telescope being arranged on light takes aim on carriage.Aim at parallel light tube cross cross wires with the binocular telescope right lens-barrel, this moment, the horizontal line at telescope right lens-barrel mil circle center overlapped with parallel light tube cross cross wires horizontal line, and this is pitching optics zero-bit.Through repeatedly adjusting, the luminous point after directional light that parallel light tube sends is assembled by telescope appears in the groove scope at graticule cross curve center of error permission.Break on this basis pin.The debugging of pitching zero-bit just is through with.
The product orientation debugging of the 4th step
Stube cable one is connected to light takes aim on the socket on mechanism chassis, the other end is connected on the socket of selsyn zeroing combination rear panel, and selsyn zeroing combination is connected on the three-phase mid-frequency inverter by cable.
Light is taken aim at the numeral demonstration that mechanism carries out respectively clockwise on orientation, the selsyn of slow rotation, and observation counterclockwise returns to zero to be made up, and light is taken aim at mechanism and is clockwise rotated, and the numeral demonstration that zeroing is made up should be biased exponent; While rotating counterclockwise, the numeral demonstration of zeroing combination should be and subtracts code.Like this show that light takes aim at the orientation homophase of orientation and launching guidance car,, if single spin-echo can exchange any two terminals of orientation synchro-transmitter stator winding terminals, can meet the homophase requirement and be that light is taken aim at is consistent with the orientation phase place of launching guidance car.
The light calibration of taking aim at product just is through with like this.
Realized that with this indoor Calibration Method debugging, the light of optical reference takes aim at that binocular telescope is indoorly debug, light is taken aim at the debugging of pitching zero-bit, light is taken aim at orientation and the zero-bit debugging.Avoid light take aim at product need arrive outfield with the emission radar truck dock debugging.Solved the outfield debug difficulties, the problem such as the zero-bit precision is low.Make debugging light take aim at become simple, easy operating.Due to the optic test benchmark having been arranged, improve light and taken aim at the consistance of product zero-bit precision, make batch light take aim at product and had interchangeability.Indoor Calibration Method of while can further carry out light and take aim at the work in everies such as Function detection, in time finds fault, fixes a breakdown.
Embodiment
