摘要: 本发明公开一种用锁相放大器对动平衡机微弱信号检测方法的实现装置,包括:信号处理电路、微处理器电路、模拟开关电路、无源低通滤波电路、校准/测量开关和数据传输电路;所述信号处理电路接收动平衡机输出的微弱信号,并将该信号进行正反两个方向放大;同时将参考信号Sref放大整形成方波信号作为斩波的开关;所述微处理器电路接收来自信号处理电路的方波信号,并对模拟开关的时机进行调整;所述无源低通滤波电路接收模拟开关输出信号;所述数据传输电路将校准/测量开关的输出信号通过USB接口传输至PC机。本发明的实现装置具有成本低的优点,且检测精度高,偏差低。
英文摘要: The invention discloses an implementation device for a method utilizing a phase-locking amplifier to detect weak signals of a dynamic balancer. The device comprises a signal processing circuit, a microprocessor circuit, an analog switch circuit, a passive lowpass filter circuit, a calibration/ measurement switch and a data transmission circuit, wherein the signal processing circuit receives the weak signal output by the dynamic balancer and can carry out forward and reverse amplification on the signals meanwhile, a reference signal Sref is magnified and reshaped to obtain a square signal as a switch of a chopping wave the microprocessor circuit receives the square signal from the signal processing circuit so as to carry out adjustment on the time of the analog switch circuit and the passive lowpass filter circuit receives the output signals of the analog switch, and the data transmission circuit transmits the output signals of the calibration/ measurement switch to a PC (personal computer) machine through a USB (universal serial bus) interface.The implementation device provided by the invention has the advantages of low cost, high detecting precision and low deviation.
