摘 要
在使用电子元器件时，首先需要了解参数。采用传统的仪表进行测量时，首先要从电路板上焊开器件，再根据元件的类型，手动选择量程挡位进行测量，这样不仅麻烦而且破坏了电路板的美观。基于单片机控制实现的RLC测量仪可以在线测量、智能识别、量程自动转换等多种功能，大大提高测量仪的测量速度和精度，扩大了测量范围。因此这种RLC测量仪既可改善系统测量的性能，又保持了印刷电路的美观，较传统的测量仪还具有高度的智能仪和功能的集成化，在未来的应用中将具有广阔的前景。
本课题主要研究内容为设计一个基于单片机的RLC智能测量仪器，能够智能地识别出待测元件是电容、电感还是电阻；能精确测量出电阻、电容、电感的参数值，同时还能加入语音播报的功能；可以实现量程电阻的自动转换，无须人工选择档位；对测量仪进行扩充后还实现了二极管、三极管的测量。

Abstract
In the use of electronic components, the first need to understand parameters.Using the traditional instrument to measure, the first circuit board from a welding device, according to the type of components, manually select range Shift to measure, this is not only troublesome but also undermine The appearance of the circuit board. Based on SCM control to achieve the RLC-measuring instrument can measure, intelligent identification, range automatic conversion, and other features, thereby greatly increasing the meter measuring speed and accuracy, expanded the range. So this RLC measuring instrument can improve the performance measurement system, and maintain the appearance of the printed circuit, the more traditional measuring instrument also is and application in the future will topics for the design of research based on the RLC SCM smart measuring instruments, smart and able to identify components under test is capacitors, inductors or resistance; can be accurately measured resistors, capacitors, inductors of the parameters, while adding Voice of the broadcast function can be automatically converted range of the resistance, not artificial selection stalls; measuring instrument to carry out the expanded also to achieve the diodes, transistors measurement.
