【摘要】 近年来,随着设施农业朝着集约化、规模化方向的发展和温室管理智能化要求的提高,温室控制系统实现远程通信进而实现温室内生产与管理的一体化,是现代智能温室发展的必然趋势。温室控制系统主要是根据外界环境的温度、湿度、光照以及风速、风向、雨量等气候因子,基于温室专家系统和用户参数设定,通过一系列控制措施,调节温室内的温度、湿度、通风、光照等环境因子,创造出适合作物生长的合适温室生态环境。本文根据温室环境控制的特点,利用传感器和数据采集卡等硬件系统对温室内的温度、湿度、光照度和二氧化碳浓度四个主要环境因子进行自动数据采集。在软件方面,系统采用LabVIEW虚拟仪器平台,大大提高了检测控制的精度和数据处理的速度,实现了温室环境参数的实时获取、采集信息的实时显示、控制信号的准确输出及数据的自动处理,减少了人为干预,增加了测控系统的稳定性。更多还原

【Abstract】 In recent years, with the development of facility agriculture which towards to intensive and scaled and the advancement of greenhouse intelligent management, greenhouse control system realizes remote communication, then realizes integration of greenhouse production and its management is an inevitable trend of the development of the modern intelligent greenhouse. Greenhouse control system is mainly based on temperature, humidity, light and wind speed, wind direction, rainfall and other climate factors of the external environment, and based on greenhouse expert system and users’ parameter setting, to regulate the greenhouse temperature, humidity, ventilation, light and other environment factors through a series of control measures, and create the suitable greenhouse ecological environment which fits the growth the crops.In this paper, according to the character of environment control in greenhouse, and using sensors, data acquisition card and other hardware to automatic collect data of four major environmental factors which is greenhouse temperature, humidity, light, carbon dioxide concentration. On software, system uses LabVIEW virtual instrument platform, greatly improves accuracy of detection and control and data processing speed. And realizes real-time acquisition of greenhouse environment parameters, real-time display of acquisition information, accurate output of control signals and automatic process of data, reduces human intervention, increases stability of measurement and control syetem.更多还原
