单片机的数据采集实验板设计

Software design of data acquisition boards based on MCU

设计的电压数据采集系统是以单片机(STC89C52)为控制核心的系统.该系统具有电路简单、功耗低、可靠性高等优点,能实现对多路模拟通道信号的数据采集与处理.并且通过ADC0809模数转换芯片把采集的电压信号转换为数字信号,再经单片机简单处理,实现将采集的数据送LED显示器进行直观显示的功能.本设计采用Keil C51语言软件编程,利用单片机内部资源简化了整个硬件电路及软件的设计,模块化处理又使得电路设计清晰合理,体积小,功效性较强.

This datum acquisition system was based on the STC89C52 which was for the control of the core,and there were many advantages with it,such as simple circuit,low power consumption,high reliability and so on.It could realize the data acquisition and processing of multi-channel simulative signals.The ADC0809 analog-to-digital conversion chip could be used to turn voltage signals into digital signals.After the processing of a simple MCU,the data will be collected and sent to LED display for visual display and ot...
