摘要
针对温室环境调控自动化程度不高的现状,设计了基于PIC16F877单片机的温室自动控制系统,介绍了温室控制的硬件组成及工作原理,给出了软件流程图。该系统采用模糊控制方法对温室的主要环境因子,如湿度、温度、光照度及CO2气体等进行智能控制,且可通过串行通信实现远程控制,提高了温室控制的自动化和实用性。
Aimed at the poor control of greenhouse environment automation, this paper features the design of greenhouse automatic control system, based on PIC16F877, and introduces the hardware composition and work principle and offers the flow charts of software. This system, depending on fuzzy control method, renders possible the intelligent control of the main environment factors, such as temperature, humidity, illuminance and Carbon dioxide. The system allows a long-distance control through the serial communication with computer, and shows a better greenhouse control automation and application.
