| 摘 要： | 通过系统的分析和总结,得出温室大气温度信号的采集传感器件所需的测量程小,精确度不高,抗干扰性较强,经济性较好的结论。并以此为依据,选用DS18B20数字温度传感器为温度采集器件,进行了温度采集系统的硬件和软件设计,实现了采集系统分布式采集温度信号的功能。同时,通过串行总线完成了采集系统与上位计算机的连接,实现了采集系统的网络化监控功能。

| Abstract: | By general analysis and conclusion,the sensor used for green house temperature collection should have an small measuring range,normal precision,low price,and good anti-interference. According to these characters above,the hardware and software of green-house temperature collection system are designed. The collection system was capable of distributed collection of temperature signal and it also realized the function of the Networked measurement by connecting the collection system and the upper computer used serial communication technology. |
