摘要
本文介绍了一种实用的利用计算机来集温度的系统实现方法,包括硬件的组织结构和软件的编制,采用AD590作温度传感器,ADC0809作模数转换器,单片机89C51作为下位机,PC机作为上位机。上位机与下位机通过PC机的RS-232串行接口实现通信。
A effective system of temperature acquisition based on computer is introduced. It includes the hardware structure and the software programming. The system uses AD590 as temperature sensor, ADC0809 as Mod- Digit switcher, macrochip 89C51 as down termination, PC as up machine. The communication between termination and up machine is realized by RS- 232 serial interface of computer.
