语音报数示波器控制电路的设计与实现

在电子技术领域中,信号幅值和周期是电量技术中重要参数之一。为了能使示波器更准确的测量,提出了基于P89C51单片机为控制核心,从而对信号幅值和周期直接测量的一种新方法。利用单片机软、硬件资源,实现信号电压幅值、周期的识别、切换和测量过程自动化。引入语音处理技术,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、精度较高等特点,具有一定的推广应用价值。

Design and application of voice oscillograph's control circuit

In the realm of electronic measurement technology,the signal' Signal amplitude and periodicity is the most important parameters.For more accurate measurements of oscillograph,a new method on Signal amplitude and periodicity of direct-measuring is presented in the paper,its control-core is based on the P89C51.By using the resource of SCM's software and hardware,it can automatically detect,switch and measure signal voltage amplitude,Cycle Recognition.What is more,it has the measurement voice output because of using new technique of voice process.The results show that it has features of stable,rapid measurement and accurate measurement high precision,so it will have wide applications in the realm of detecting technology.
