| 为了提高超声波换能器电源的智能性和通用性，本文提出了一套以高性能dsPIC30F4011单片机为控制核心的换能器电源解决方案，并进行了相关的软硬件设计。该方案基于键盘输入选择标称频率拓宽了换能器的标称频率选型范围，基于最大电流法检测谐振点设定最佳频率保证了换能器电声转换的高效性，基于电压反馈检测调整输出电压和保持换能器的功率稳定，主要检测过程采用软件实现。实验结果证明采用该方案的超声波换能器电源具有现实可行性。 |
| 英文摘要: |
| In order to improve the intellectuality and generality of traditional ultrasonic transducers power, this paper develops a set of transducer power solutions based on the control core of high-performance dsPIC30F4011 microcomputer and relates hardware and software design. The scheme is based on the nominal frequency selection of the keyboard to widen the nominal frequency of the transducer selection scope, based on the maximum current method to detect the resonance point and set the optimum frequency ensuring the largest electro-acoustic transducer conversion efficiency, based on voltage feedback detection to adjust the output voltage and maintain transducer power stable, the main detection process is used by software implementation. The experimental results prove that the scheme of the ultrasonic transducer power has realistic feasibility. |
