摘要
构建了一种蔬菜大棚智能环境参数测控系统。该系统采用分布式结构,CAN总线通讯方式。系统通过实时检测温室环境温度、湿度、光照度和CO2浓度以及土壤湿度,与预设的参数指标进行比较,如果超出范围,自动打开控制系统,控制电灯、风机、喷水器、加热器、降温泵等进行操作,使蔬菜生长环境实现自动控制。上位机软件采用VB语言编写,可实现数据的存储、显示、控制参数设置、数据查询和打印等功能。
One kind of intelligent measurement and control system was introduced. It used distributed control system and CAN Bus. This system can simultaneously detect the temperature, humidity, illumination, the density of the greenhouse. If the parameters went beyond the ideal parameters, the system will automatically control the electric light or the fans or the water jet or the heater to work. The software of the PC used VB. This program can store and show the data. It can also search and print the data, etc.
