基于单片机的多路数据采集系统设计

Design of Multi-Channel Data Acquisition System Based on MCU

数据采集系统在石油化工行业广泛应用,文章给出一种ATmega16单片机控制的多路数据采集系统的设计方案。单片机将现场采集的多路模拟信号转换为数字量,通过LCD12864将其在现场显示,通过AT24C64将数据进行存储,现场采集的信号还可以通过485总线传输至上位机。

Data acquisition systems are widely used in the petrochemical industry, the paper presents a design ATmega16 MCU multi-channel data acquisition system. Single-chip multi-channel analog signal is converted to digital will be collected at the scene of the amount by LCD12864 display it in the field, the data stored by AT24C64 signal site collection can also be transmit-ted through the first 485-bit machine.
