基于ZYNQ的激光陀螺寻北仪的设计

Design of the north-seeking of laser gyro based on ZYNQ

在现代化战争中的武器系统以及民用勘测领域中,寻北技术发挥着无与伦比的作用。基于此背景,该文设计了一种基于ZYNQ的光纤陀螺寻北仪。该系统由XB185D单轴闭环光纤陀螺通过串行422通信接口将数据发送给ZYNQ,并通过AD模块AD7693对两路石英加速度计进行数据采集,利用温度传感器DS18B20进行温度数据采集。以XC7Z020为逻辑控制核心,通过四位置寻北算法解析北向角度,通过串口总线将结果发送到上位机上。经测试表明,该系统稳定可靠,能准确地定位北向,其误差范围在0.3°内。

Weapon systems in modern warfare and north-seeking technology in the field of civil survey play an unparalleled role. Based on this background,a ZYNQ-based fiber optic gyroscopic northseeking system is designed. The system is used by XB185D single-axis closed-loop fiber gyro to send data to ZYNQ via serial 422 communication interface and to two quartz accelerometers via AD module AD7693,and temperature sensor DS18B20 for temperature data acquisition. The XC7Z020 as the logical control core analyzes the north-seeking angle through the four-position north-seeking algorithm,and finally sends the results to the upper computer by the serial bus. The test shows that the system is stable and reliable,can accurately locate the north direction,and its error range is 0.3 degrees.
