|
摘要
针对目前农业生产逐步向节约型转变的需求,设计了一种基于比例—积分—微分(PID)算法,并以STC12C5A60S2单片机为核心控制器的温度控制系统。系统可根据温室内农作物对生长环境温度的要求而设定合适的温度,同时能够根据实测温度值偏离设定温度值的程度,自动启动相应的加热或降温设备,调节室温至设定范围,实现了快速、稳定、精确控制。经模拟仿真分析及软硬件测试,可知设计的系统运行稳定,控制精度较高,达到了理想效果,具有一定的应用价值及推广价值。
A temperature control system based on proportional-integral-differential( PID) algorithm and using STC12 C5 A60 S2 microcontroller unit( MCU) as the core controller is designed,in view of current agricultural production gradually shift to the needs of the economy. The system can set appropriate temperature,according to temperature requirements of different crops in greenhouse growth environment,and start the corresponding heating or cooling equipment automatically according to the degree of the measured temperature deviate from the set temperature to adjust the room temperature to the set temperature range,achieve a rapid,stable and accurate control. Through simulation analysis and software and hardware test,it shows that the system achieves ideal effect because of stable running and high control precision,it has certain application value and popularization value.
