国外对设施农业环境监控技术研究较早,始于20世纪70年代,当时主要是采用模拟式的组合仪表,采集现场信息并进行指示、记录和控制,80年代末出现了分布式控制系统,目前正开发和研制计算机数据采集控制系统的多因子综合控制系统。美国、荷兰、日本等国的特点是自动化和机械化的设施栽培,生产中的温度、湿度、光照、施肥、喷药等,均实现了自动化控制和网络化管理。在国内,与荷兰、美国等设施农业强国相比,我国设施农业的
Foreign research on facility agricultural environment monitoring technology started earlier in the 1970s. At that time, it mainly used analogue instrument cluster to collect field information and instruct, record and control. In the late 1980s, a distributed control system appeared. Currently, Is developing and developing computer data acquisition and control system of multi-factor integrated control system. The United States, the Netherlands, Japan and other countries are characterized by automated and mechanized facilities cultivation, production of temperature, humidity, light, fertilization, spraying and so on, have achieved automatic control and network management. In China, compared with facilities in the Netherlands, the United States and other agricultural powerhouses, our country facilities agriculture
