Description
Technical Field
The invention belongs to the technical field of maintenance and detection of a follow-up system, and particularly relates to a performance maintenance and detection device of the follow-up system.
Background
At present, the maintenance and detection means of the follow-up system mainly depend on devices such as a stopwatch, a recording pen, a recorder and the like. When the high-low performance index is measured, the recording pen is connected with the barrel, the recorder translates at a certain speed, when the barrel moves, the recording pen moves with the barrel, the motion track of the barrel is drawn on the recorder, and the high-low performance index is analyzed according to the curve.
When measuring the horizontal performance index, a technician needs to operate the barrel to rotate for a circle at a fixed speed and record the used time by using a stopwatch, so that the whole test process is complex to operate, low in precision, long in time consumption and poor in flexibility, and the tester is required to be very familiar with the test process and the data processing method of the performance index, and the method is not suitable for the automatic high-precision detection requirement.
Therefore, related scientific research personnel develop the research of the follow-up system performance maintenance detection technology successively, and the accuracy and the automation degree of equipment detection are greatly improved. The prior related technologies mainly comprise the following contents: the first AC full-electric gun control system and the digital high-power AC full-electric gun control system are successfully developed by certain academy of engineering, and are matched with a one-stop non-contact gun control system performance detection device. The follow-up system in-situ detector and the comprehensive detector developed by the prior art personnel can realize in-situ detection of 9 cannon control components such as a gyroscope and the like, are used for maintenance teams and team members to detect in an 'in-situ' mode, and can also realize performance working condition detection of each component corresponding to intermediate maintenance. The method can correct the parameters such as inconsistent firing angles of the artillery, dislocation of aiming lines and the like by the built measuring system based on the method, can effectively solve the problems of large error, complex operation and the like existing in the process of checking and correcting the artillery aiming device in the prior art, and is favorable for being integrated with other detecting equipment; although the method has high precision, two high-precision theodolites and one computer are needed for detection. Fourthly, the existing method for realizing the non-contact detection of the dynamic performance of the gun control system by utilizing the photoelectric technology and the computer technology is provided; the system obtains the motion state characteristics of the artillery and the gun turret by detecting the motion of the markers through the CCD and the computer, and carries out analysis and calculation according to the motion state characteristics to finally realize the dynamic performance evaluation of the artillery control system; the method requires preparation of a green laser pen, a projection screen, and installation of an image acquisition system in both horizontal and vertical directions.
The follow-up system performance detection device and the follow-up system performance detection method are either used for single-component level detection or in-situ detection of follow-up system performance. When a certain type of self-propelled gun shoots during traveling, the gun deviates from a firing angle aiming at a target due to vibration and steering of a vehicle body, a gyroscope in a follow-up system immediately sends a signal proportional to the deviation angle, the signal is amplified to control an actuating mechanism, the actuating mechanism enables the gun to tend to and approach to recover to the original firing angle, and in fact, some small deviations always exist, and the stable precision of the follow-up system is greatly influenced due to the deviated firing angle.
In addition, due to the influence of machining errors and installation errors, the positions of the gyroscope group and the barrel are inconsistent, and the installation error angle between the gyroscope group and the barrel must be calibrated and compensated.
The method solves the outstanding problems of complex operation, low precision, long time, poor flexibility, high requirement on personnel quality and the like in the maintenance and detection process of the servo system at present, and becomes the problem to be solved in the maintenance and detection process of the servo system.
