农业大棚环境控制系统设计

Design of Agricultural Greenhouse Environmental Control System

农业大棚实现了对农作物在种植过程中其生长环境参数的精确测量及控制,从而达到对农作物生长环境改善的目的,这样不仅能避免因自然灾害给农作物带来的损失,还可以提高农作物的产量。因此设计了一种简单的农业大棚环境控制系统,利用温湿度传感器DHT11检测大棚内部的温湿度,利用光照传感器BH1750检测光照强度,将传感器检测的数据传输给单片机STC89C52RC,若测得的数值不在设定的范围内,则系统就会启动相对应的执行模块进行自动调节,同时在液晶屏LCD1602上面显示出当前的温湿度值和光照强度,从而保证农作物能够在相对稳定的环境中生长。经测试,该系统基本可以实现农业大棚环境的自动控制,而且具有较高的测量精度、稳定的性能,同时又有一定的可移植性。

Agricultural greenhouses realize accurate measurement and control of the growth environment parameters of crops during the planting process,thereby achieving the purpose of improving the growth environment of crops.This can not only avoid losses to crops caused by natural disasters,but also increase crop yields.Therefore,a simple agricultural greenhouse environmental control system was designed.The temperature and humidity sensor DHT11 was used to detect the temperature and humidity inside the greenhouse,the light sensor BH1750 was used to detect the light intensity,and the data detected by the sensor was transmitted to the single-chip microcomputer STC89C52RC.If the measured value is not within the set range,the system will start the corresponding execution module to automatically adjust,and at the same time,the current temperature,humidity values and light intensity will be displayed on the LCD screen LCD1602,thereby ensuring that the crops can grow in a relatively stable environment.After testing,the system can basically realize automatic control of the agricultural greenhouse environment,and has high measurement accuracy,stable performance,and certain transferability.
