摘要
设计了以TI公司生产的ADC0809为模数转换器的数据采集系统。系统通过采样电路将模拟信号转换为0～5V电压输入,通过ADC0809进行模数转换,由AT89C52单片机完成数据的处理及显示。系统实现了8路模拟数据的采集、转换及显示,通过设计数据采样电路及处理程序可应用于各种数据的测量。
This paper designs a data acquisition system with ADC0809.The sampling circuit through the system converts the analog signal to the 0～5V input voltage,analog to digital conversion by ADC0809,processingand display of datafrom AT89C52 microcontroller.System to achieve a 8 analog data acquisition,conversion and display,through the design data sampling circuit and processing program can be applied to all kinds of data measurement.
