| 中文摘要: |
| 针对目前测深仪、声呐及多普勒计程仪保障维修过程中对换能器技术状态鉴定所面临的困境,研制了基于小信号电桥法的换能器测量仪器,通过单片机、信号发生器、电桥电路法、电压测量法测量换能器的动态等效电容、等效电阻、谐振频率等技术指标,并通过软、硬件予以实现,经实践检验,有效地提高了对换能器技术状态鉴定的效率。在日常修理中有很强的实用性。该方法已在回声测深仪修理调试检测设备中得到应用。 |
| 英文摘要: |
| The identification of transducers' technical conditions is difficult during the routine maintenance of echo sounder, sonar and DVL. A measurement based on small-signal bridge method is developed. By the single-chip microcomputer, signal generator, bridge circuit method and voltage measurement method, the transducer's dynamic equivalent capacitance, equivalent resistance and resonant frequency are measured, and this measurement could improve the efficiency of identifying transducers' technical conditions effectively. |
