两栖装甲突击车炮控系统稳定精度检测系统研究

Research on Test System for the Stabilization Accuracy of Gun Control System of Amphibian Armored Assault Vehicle

稳定精度是两栖装甲突击车炮控系统的一项关键性技术指标,直接影响到武器系统的威力发挥。以动力调谐陀螺仪为传感器的检测原理,采用ADI公司的ADSP-BF532和高精度模数转换芯片AD7677,实时采集动力调谐陀螺仪的信号并处理,通过最小二乘法拟合出漂移曲线,进而求出稳定精度。实验结果表明:该检测系统的精度高、通用性好并能快速准确地对稳定精度进行检测。

The stabilization accuracy was key technical indicators of gun control system of amphibian armoured assault vehicle（AAAV）,and its performance affected directly power of gun weapon system.The test principle using DTG for sensors was introduced.The signal of dynamically tuned gyroscope（DTG） was sampled and processed using ADSP-BF532 of Analog Devices,Inc and high accuracy ADC AD7677,the drift curve was obtained by least-square curve-fitting,and the stabilization accuracy was calculated.The result of experiment indicates that the system has advantages of high measuring accuracy,good generality,and can measure the stabilization accuracy with rapidness and preciseness.
