摘　　要：为解决光纤自愈系统中机械手防误操作效果差的问题,提出了一种结合光磁电脉冲的光纤自愈系统数据监测方法。首先,通过光电与磁电编码器分别获得光纤自愈系统机械手的数据,并采用小波滤波等方法消除噪声对监测数据带来的影响。其次,采用光电式编码与磁电式编码互补校验的方式进行了光纤自愈系统机械手数据采集,使多个编码器相互配合、互为校验,从而提高机械手监测数据的准确性、避免单个装置故障造成的数据偏差。最后,在某试验环境中进行了测试。测试结果表明,光纤自愈系统监测准确率为99.87%。该方法能有效提高光纤自愈系统机械手监测数据的准确性。To solve the problem of poor anti-maloperation of manipulator in fiber optic self-healing system,a data monitoring method of fiber optic self-healing system combining with optical-magnetic-electrical pulses is proposed.Firstly,the data of the manipulator of the fiber optic self-healing system are obtained by photoelectric and magnetoelectric encoders respectively,and wavelet filtering and other methods are used to eliminate the influence of noise on the monitoring data.Secondly,the fiber optic self-healing system manipulator data acquisition is carried out by using the complementary checking methods of photoelectric encoders and magnetoelectric encoders,so that multiple encoders cooperate with each other and check each other,thus improving the accuracy of the manipulator monitoring data and avoiding the data bias caused by the failure of a single device.Finally,it is assessed in a test environment.The test results show that the monitoring accuracy of the fiber optic self-healing system is 99.87%.This method can effectively improve the accuracy of manipulator monitoring data of fiber optic self-healing system.
