振动信号无线收集装置
摘要：
本发明提供了一种振动信号无线收集装置，包括一接收振动信号的金属板、连接所述金属板的压电放大器、与所述压电放大器连接的电流放大器、遮罩于所述压电放大器和电流放大器外围的金属外壳；所述金属板在收到振动信号时发生共振并产生电势，并经所述压电放大器和电流放大器将电势最终转换成电流信号。与现有技术相比，本发明振动信号无线收集装置利用空气为介质，通过金属板的共振接收振动信号，从而使金属板产生高低不同的电势，进而将电势转换成电流信号，以得出物体振动的周期，以及间接计算频率，其结构、原理简单，制造成本低廉，具有很广的应用范围及极佳的经济性。
摘要（英）：

The invention provides a vibration signal wireless collecting device which comprises a metal plate, a piezoelectric amplifier, a current amplifier and metal outer shells. The metal plate receives vibration signals. The piezoelectric amplifier is connected with the metal plate. The current amplifier is connected with the piezoelectric amplifier. The metal outer shells cover the outer peripheries of the piezoelectric amplifier and the current amplifier. The metal plate generates resonance and potential when receiving the vibration signals, the potential is finally converted into current signals through the piezoelectric amplifier and the current amplifier. Compared with the prior art, the vibration signal wireless collecting device uses air as media, the vibration signals are received through resonance of the metal plate, so that the metal plate generates the potential with different magnitudes, then the potential is converted into the current signals, the cycle of object vibration is obtained, frequency is computed indirectly, the structure and the principle are simple, manufacturing cost is low, and the vibration signal wireless collecting device is wide in application range and great in economy.
