摘要
介绍了基于USB串口多点温度采集系统总体方案。给出了系统的硬件组成,利用AT89S52单片机作控制器,通过多个数字温度传感器DS18B20进行温度采集,采用USB接口芯片CH372将接收到的数据上传到PC机进行处理。软件主要包括单片机控制程序、USB驱动程序及上位机接收数据和处理数据程序,给出了程序流程图。
Architectures program about multi-point temperature acquisition system is introduced based on the interface of USB. Composition of hardware in the system is given. AT89S52 microprocessor is adopted as CPU, many digital temperature sensors DS18B20 is adopted to temperature acquisition. The received data is uploaded to the PC for processing though USB interface chip CH372.Software of system main includes microprocessor control program,USB driver program and PC to receive data and data processing program. In this paper, Flow chart of program are given.
