摘　　要：由于当前臭氧发生器高频电源谐振频率检测方法具有昂贵、危险等缺点,设计一种基于声波频谱分析的高频电源谐振频率检测仪器。通过分析臭氧发生器工作环境下的声波数据与高频电源谐振状态的关系,找到测量谐振频率的方法。该仪器使用STM32单片机作为核心控制及计算单元,通过声波采集电路将声波数据传送给单片机,单片机基于声波数据使用频谱分析程序测量出谐振频率。实践分析结果表明,基于声波分析的臭氧发生器电源谐振频率测量仪具有高效、安全、经济等优点。Because the current ozone generator high-frequency power source resonance frequency detection method has the disadvantages of being expensive and dangerous,a high-frequency power source resonance frequency detecting instrument based on acoustic spectrum analysis was designed.The method of measuring the resonant frequency was found by analyzing the relationship between the acoustic wave data in the working environment of the ozone generator and the resonant state of the high-frequency power source.The instrument used STM32 single-chip microcomputer as the core control and calculation unit,and transmitted the sound wave data to the single-chip microcomputer through the sound wave collecting circuit.The single-chip microcomputer used the spectrum analysis program to measure the resonance frequency based on the sound wave data.The results of practice analysis show that the ozone generator power supply resonant frequency measuring instrument based on acoustic wave analysis has the advantages of high efficiency,safety and economy.
