本系统分电压测量和信号产生输出两大部分，电压测量部分以模拟电路为主，配合放大模块、A/D转化模块、显示模块；通过凌阳单片机进行数据处理，在误差允许范围内显示测量电压值，并播报语音。信号产生以直接数字式频率合成器(Direct Digital Frequency Synthesis,简称DDS或DDFS)为核心，经过AT89S52对DDS芯片内部进行控制，使之输出标准正弦波形，利用编程实现频率预置、步进，达到电压输出频率的可调节步进。
信号输入后进行整流滤波，然后进行量程选取。通过AD620进行放大，用TLC2543进行A/D转换，分别送入测量和显示作为待测信号。测量部分信号进入凌阳单片机，通过LCD输出测量值，并通过语音电路播报语音。信号输出部分进入AT89S52，通过键盘的操作，来控制AD9854输出想要的波形。
本系统的特点是，测量量程大10mA－500V都可以测量，而且配备上独特的语音播放电路，键盘操作输出显示波形。 |

The system breakdown voltage measurement and signal output two most voltage measurement part in the main circuit simulation, tie amplifier module, A / D conversion module, module; Sunplus microprocessor through data processing, in the range of allowable error voltage measurements show, and broadcast voice. Signals generated by direct digital frequency synthesis (Direct Digital Frequency Sy nthesis, DDS or short DDFS) for the core, After AT89S52 right DDS chip internal control to make it the standard sine-output, Programming using preset frequency, step by step, to achieve the output voltage adjustable frequency step. Signal input rectifier after filtering, then select range. Click through AD620 for use TLC2543 for A / D conversion. Measurement were taken and shown as analyte signal. Measurement of signal entering Sunplus MCU, LCD output through measurements, and by voice circuit broadcast speech. Part of the output signal into AT89S52, through the operation of the keyboard to control unwanted AD9854 output waveform. The system is characterized by large measurement range 10 mA - 500V can be measured. and equipped with a unique voice broadcast circuit, keyboard output waveform shows.
其实英文摘要不能那么长的,中文限制在一百字以内.你看着办吧. |
