摘　　要：温度检测系统是智能温室中的重要系统之一,因为温度决定着卷帘系统、风机系统、补光系统等自动控制系统模块的工作,而且精确的温度采集系统还决定着植物的生长。为了精确采集温室的温度,本文设计了一款基于嵌入式微控制器单片机作为上位机和美国DALLAS公司的可编程分辨率的1-Wire数字温度传感器DS18B20构成的多点温室温度检测采集系统,通过在EDA软件——Proteus平台中进行电路设计与仿真,实现了多点温度采集与显示。在实际应用中,该多点温度检测电路的特点是温度采集精度高、电路成本低、功耗小、系统稳定性高,可以推广应用。The temperature acquisition system is an important system of an intelligent greenhouse, because the temperature determines the working of shutter system,fan system,fill light systems and so on. The accurate temperature acquisition system also determines the growth of plants. In order to accurately capture the greenhouse temperature,this paper designs a greenhouse multi-point acquisition system which includes a microcontroller based on an embedded microcontroller as a PC and the programmable resolution 1-Wire digital temperature DS18B20 sensor made by DALLAS.This multi-point temperature measurement system has characterized by high precision temperature acquisition,low cost,lower power consumption. In actual greenhouse promotion applications,high stability of the system can meet the actual greenhouse detect multi-point temperature.
