摘要

为应对系统采集环境恶劣和对采集的数据实时性要求高的特点,基于C8051F007单片机设计了一款低成本、多通道集成数字信号与模拟信号采集处理下位机系统。对于模拟信号由C8051F007的片上A/D转换单元转换为数字信号,同时结合基于MFC(Microsoft Foundation Classes,微软基础类库)开发的上位机系统显示处理数模信号,并通过UART-USB了实现了上下位机的通信。实验证明:该系统可以实现多路数字与模拟信号的采集,同时可以进行采集信号的显示处理。
        Considering relatively harsh environment of the acquisition system and the highly real-time requirement,having C8051 F007 SCM based to design a low-cost integrated lower-level computer system was implemented to collect and process multi-channel digital and analog signals. Through C8051 F007 SCM's A/D conversion unit,the analog signal can be converted into the digital signal and then to be displayed on the MFC(Microsoft Foundation Classes)-based upper computer system developed,including the communication between the upper and lower computers through UART-USB. Experimental results show that,this system can realize acquisition and display and processing of the digital and analog signals.
