| 摘 要： | 针对DT890A型普通数字万用表,以凌阳SPCE061A单片机作为核心器件,提出了一个简单实用的语音报读方案。通过获取显示数据及档位信息,实现了显示数字和单位的自动报读,且报读节奏可控。通过对获取数据做适当的处理(如多值平滑),改善了测量准确度,增加了相对值计算功能,扩展了被测电量变化的观察和电阻电容的比对筛选功能。由于不必看万用表显示的数值及量程换算就能得到测量结果,使得数字万用表的操作更方便、更友好。

| Abstract: | Using Sunplus SPCE061A MCU as the core unit,this paper proposes a simple and practical scheme of speech reading for the DT890A Multi-meter.By obtaining the measured values and corresponding gears,the measured values and units are automatically read by voice,and reading rhythm can be controlled.The measurement accuracy is improved by properly processing(e.g.multi-value smoothing) the obtained data.The functions of multi-meter,i.e.,calculation of relative values are enhanced.In addition,the following two functions are extended:the observation of measured values changes,and the comparison and filter of resistors and capacitors.The measurement results without looking at the values shown by multi-meter and without range conversion can be obtained.Therefore,the operation for digital multi-meter has become more convenient and friendlier. |
