摘要
介绍了基于RS485串行总线标准的温度采集系统的硬件和软件设计。温度数据的采集由以AT89S52单片机为核心的系统完成,采集的数据经RS485串行总线上传给计算机进行存储和处理。系统的软件包括单片机程序和计算机程序,分别应用C语言和VB语言编写。相应的硬件和软件抗干扰措施保证了系统的稳定性和可靠性。
The hardware and software design of the temperature acquisition system based on RS485 serial communication criterion isintroduced. The acquisition of temperature data is finished by the system taking AT89S52 MCU as core. Collected data can be sentup to computer through RS485 serial bus,stored and processed in it. The software of this system includes MCU and computer pro-grams,programmed with C language and VB language. Some corresponding software and hardware anti-disturbance measures assurethis system＇s stability and reliability.
