摘要 针对传统的水下枪械自动机测试系统存在的灵敏度低,噪声严重,后期数据处理繁琐等问题,提出一种改进型枪械自动机测试系统。采用低导磁材料代替传统永磁型感应测速传感器的铁芯,并以漆包线缠绕坡莫合金作为感应线圈用以增强其灵敏度,解决了传感器因内部铁心线圈产生涡流影响测量精度的问题;利用小波变换对采集数据进行降噪处理和突变点的检测,准确捕捉自动机运动过程。经试验验证,测试结果可精确至m V,系统整体不稳定度为1.65%。 To improve the sensitivity,reduce the noise and simplify the data processing of the gun automation motion measurement system underwater,an improved design of the measurement system is proposed.Using low permeability metal replaces the iron core of the induction sensor,and twining around the Pomo alloy as the induction coil the induction sensor’s sensitivity is enhanced.These methods solve the problem of measuring accuracy of the eddy current caused by the internal core coil.Then,the wavelet transform is used to reduce the noise and accurately capture the automatic motion process.After several tests,the results can be accurate to mV,and the system instability is 1.65%.
