设施农业大棚多点温度采集报警装置

Agricultural greenhouse facilities multipoint temperature collection and alarm device

对于农业大棚采用单个温度传感器测温不准,难以精准控制的问题,本文介绍了一种基于DS18B20单总线温度传感器的设施农业大棚多点温度采集报警装置的设计。该系统主要由AT89C51单片机、DS18B20单总线温度传感器检测电路、报警电路和显示电路构成。通过Proteus平台的仿真和调试,系统可以把采集到的各点温度值加以运算并且求出平均值,然后在显示器上显示出来,从而可以验证其在实际应用中的可行性。

For the problem that a single Temperature Sensor cannot measure the temperature precisely, This paper introduces a single-bus temperature sensor DS18B20 agricultural greenhouse facilities multi-point temperature acquisition alarm device design, which is composed of AT89C51 microcontroller, DS18B20 single-bus temperature sensor circuit, alarm circuit and display circuit. By the Simulation and debug of the Proteus platform, The system can calculate the average values for the temperature of each point it collected,then displayed on the monitors, so it can be tested whether it is the feasible in practical application.
