【摘要】 在电子技术领域中,信号频率是电量技术中最重要的参数之一,为了能更准确的测量,提出了基于Phlips新一代P89C51单片机为控制核心,从而对信号频率进行测量的一种新方法。充分利用单片机软、硬件资源,结合ICM7226高集成度计数器所具有强大的功能,实现信号幅值、频率量程、闸门时间的识别、切换、测量过程自动化;引入语音处理新技术,实现测量结果语音报数。实际应用表明,该方法测量稳定、快速、结果准确。同时该项技术在检测技术领域中,具有广泛的应用前景。更多还原

【Abstract】 In the realm of electronic measurement technology, the signal’s frequency is the most important parameters. In order to make the measurement more accurate, a new method on frequency-measuring is provided in the paper,its control-core is based on the P809C51, an updated Philips SCM (single-chip microcomputer). By using the resource of SCM and high-integrated counter ICM7226 fully, it can automatically detect, switch and measure signal amplitude, frequency range and gating time. What is more, it has the measurement voice output because of using new technique of speech process. Its features of stable, rapid measurement and accurate measurement results are verified in practice, so it will have wide applications in the realm of detecting technology.更多还原
