基于AT89C51制冷系统信号采集接口研究与设计

Research and Design of Refrigeration System Signal Collection Interface Based on AT89C51

空调制冷设备的控制系统中有大量的信息要处理,其中有使用中的室内温度设置和控制外,还有设备运行中的参数需要监控、调整,如排气温度、化霜控制、室外温度、高低压力、室内盘管温度等,其中大多是模拟信号。本文就关于ADC0809芯片与AT89C51单片机如何进行模拟信号的采集与转换的软、硬件进行研究。

Air conditioning refrigeration equipment control system has a great deal of information to deal with, besides it has indoor temperature setting and control, the operation of equipment parameters need to monitor, adjust, such as exhaust gas temperature, the defrosting control, outdoor temperature, pressure, the indoor coil temperature, most of which is an analog signal. This paper researches the soft and hardware to analog signal acquisition and conversion about ADC0809 chip and AT89C54.
