舰船惯导系统陀螺电机多信息测试系统设计

摘要

陀螺仪是舰船惯导系统的核心组成部件。陀螺电机直接为陀螺仪提供驱动力矩，其工作状态直接决定了陀螺仪性能。针对陀螺电机的测试需求，构建了基于PXI硬件架构和LabVIEW软件平台的陀螺电机多信息测试系统。系统基于N I4070数据采集设备，实现了陀螺电机声音、转速传感器、电压、电流等信息的无损测量，为陀螺电机特征参数的提取和预测提供数据依据，为陀螺仪及舰船惯导系统的性能评估提供技术途径。%Gyro is the core component of the ship inertial navigation system .Gyro motor directly provides driving mo-ment for gyro .Its working condition directly determines the performance of the gyro .In view of the gyro motor test require-ments ,the multi-information test system of gyro motor based on the hardware structure PXI and the LabVIEW software platform is constructed .The system has realized the nondestructive measurement of information such as gyro motor noise , rotating speed sensor ,voltage and current based on NI4070 data acquisition equipment .It provides data basis for the extrac-tion and prediction of characteristic parameters of gyro motor .And it provides technical way for the performance assessment of the gyro and the ship inertial navigation system .
