Description

technical field [0001] The invention relates to the technical field of artillery. Background technique [0002] The gun adjustment accuracy is the difference between the actual orientation of the gun barrel and the expected orientation determined by the input parameters after the gun adjustment is completed. It reflects the error between the theoretical value after the fire control system sends out the height and azimuth target values, and the artillery follow-up system transfers the firepower axis to the designated position. At present, methods such as double theodolite space intersection method, image recognition method, angular displacement sensor method and total station method are mainly used in the gun adjustment accuracy inspection of ground artillery, self-propelled artillery and rocket launcher. However, in the measurement of anti-aircraft guns, since the anti-aircraft guns can rotate 360 ​​degrees, when the barrel rotation angle is greater than 90 degrees, methods...

Problems solved by technology

However, in the measurement of anti-aircraft guns, since the anti-aircraft guns can rotate 360 ​​degrees, when the barrel rotation angle is greater than 90 degrees, methods such as image recognition methods, angular displacement sensor methods, and total station methods cannot locate the marking points of the muzzle. , so it is impossible to realize the accuracy detection of anti-aircraft gun adjustment

Although the double theodolite intersection method can achieve a certain range of gun adjustment accuracy detection, this method requires two theodolites. During the test, it is necessary to first determine the two marking points, and then carry out the two theodolites. There are many projects, many personnel are required, and human factors are large; and, when the antiaircraft gun barrel rotates at a large angle, in order to find the marking point, it is often necessary to adjust the position of the theodolite, which increases the difficulty of the test and prolongs the test cycle; and During the test, the turret blocked the positioning point, even if the position of the theodolite was adjusted, the measurement could not be carried out

Therefore, using the double theodolite intersection method, the test period is long, the inspection conditions are harsh, and the human factor is large, so it is difficult to reflect the real accuracy index requirements
