| 摘 要： | 为实现温度的集中控制,利用AT89S52单片机及DS18B20单线数字传感器实现由一个温度采集节点、4个温度节点和一台主单片机构成分布式的温度监控网络。主机通过多机通信的方式查阅各个节点的温度,并能够实现发送命令调节各节点温度报警的上下限,实现超温报警、人工干预及自动调节等功能,主机选择数码管显示接收到的温度,从机选择液晶显示器显示采集的温度,主从机能实现数据的实时更新与对比。

| Abstract: | In order to realize the centralized control of temperature, By using AT89S52 MCU and DS18B20 （single wire digitalsensor） consists a temperature acquisition node, Four temperature nodes and one host MCU constitute a distributed temperaturemonitoring network. Host MCU using multi -computer communication way to refer to the temperature of each node, And send thecommand to adjust the node temperature alarm limits, so can realize the over temperature alarm、 human intervention and automaticcontrol, host select LED display the received temperature, slave MCU choose LCD display the temperature of the acquisition, hostand slave MCU can realize data update in real time and contrast. |
