摘　　要：设计以C8051F020微控制器为核心,采用片上16路ADC实现多路数据采集,通过CH372 USB接口芯片与PC机通信.本文叙述了数据采集器的系统结构,给出了采集器AD部分和USB部分硬件设计的要点,讨论了内置固件模式在固件程序设计中的优点及其工作流程、采集器与PC机通信的数据格式以及PC端软件的设计思路和流程.The design takes C8051 F020 MCU as the core. The on-chip 16-channel ADC is used to accomplish the multi-channel data acquisition. CH372 USB interface chip is used to communicate with PC. This paper describes the system structure of the data acquisition device. The key points in the hardware design of AD and USB in the data acquisition device are also listed. The advantage and working flow for embedded firmware mode in the firmware program design, the communication data format between device and PC, the design idea and flow chart of the software running on PC are also discussed.
