Description

Technical Field

[0001] This invention belongs to the field of dynamic control technology for photoelectric tracking equipment, specifically relating to a multi-scenario adaptive tracking adjustment method for a photoelectric turntable. Background Technology

[0002] Existing photoelectric turntable tracking control methods mostly employ fixed parameter logic. When faced with different target motion states (uniform speed / acceleration / turning) and external environmental disturbances (light wind / vibration), they are prone to tracking overshoot or lag. Furthermore, manual adjustment of control parameters is required, making the operation complex and unable to adapt to dynamic changes in various scenarios, thus compromising tracking accuracy. A tracking adjustment method that can automatically adapt to multiple scenarios is needed to solve these problems.

[0003] To address this, the present invention presents a multi-scenario adaptive tracking and adjustment method for an optoelectronic turntable. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-scene adaptive tracking and adjustment method for an optoelectronic turntable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-scene adaptive tracking and adjustment method for an optoelectronic turntable, comprising a target motion state recognition module: S1: Receives target position data output by photoelectric sensor in real time, and calculates target velocity and acceleration based on position changes within adjacent 100ms. S2: Status recognition delay ≤50ms, providing a precise basis for subsequent parameter adjustment; Multi-scene tracking parameter adaptive adjustment module: S3: Built-in parameter adjustment rule library, automatically matches tracking parameters according to the target's motion state; S4: Simultaneously receive data from the turntable vibration sensor. When the vibration acceleration is greater than 0.3g, automatically add 5% compensation to the turntable rotation speed to offset the tracking offset caused by vibration.

[0006] Preferably, in step S1, the target position data includes azimuth and elevation angles.

[0007] Preferably, in step S3, the tracking parameters include the turntable rotation speed and adjustment accuracy.

[0008] Preferably, the calculation of the target's velocity and acceleration in step S1 specifically includes: S11: when the velocity is ≤2° / s and the acceleration is ≤0.5° / s 2 It is determined to be "uniform motion"; S12: When velocity > 2° / s and acceleration > 0.5° / s 2 It was determined to be "accelerated motion"; S13: When the azimuth / elevation angle changes in opposite directions and the change is greater than 1° at adjacent times, it is determined as a "sudden turn".

[0009] Preferably, step S3 specifically includes: S31: "Uniform motion" scenario: set the turntable rotation speed to 3° / s and adjust the accuracy to ±0.3°, with the main goal of smooth tracking and avoiding energy waste; S32: "Accelerated Motion" scenario: Automatically increases the turntable rotation speed to 6° / s, maintains adjustment accuracy at ±0.3°, and quickly keeps up with the target's motion rhythm; S33: "Sudden Turn" scenario: Instantly increase the turntable rotation speed to 8° / s and temporarily relax the adjustment accuracy to ±0.5°, prioritizing ensuring that the target is not lost, and restore normal accuracy within 100ms after the turn stabilizes.

[0010] Compared with the prior art, the beneficial effects of the present invention are: Automatically identifies target motion state, eliminating the need for manual parameter adjustment, reducing operational complexity by 70%, and adapting to dynamic changes in multiple scenarios; Multi-scenario parameter adaptive adjustment improves tracking response speed by 60% and reduces target loss rate to below 1% in sudden turning scenarios; With built-in vibration compensation logic, the tracking accuracy remains within ±0.3° in complex environments, and the stability is significantly better than that of fixed parameter control; The software logic is lightweight and can be integrated into existing photoelectric turntable control systems, resulting in low upgrade costs and strong compatibility.
