摘要
综述了控制环境植物生产系统中营养液检测与控制技术的研究进展,通过对几种现有营养液检测和控制技术进行分析比较,可以看到它们在不同程度上存在着成本高、可靠性较低和智能化程度低等问题。为满足控制环境植物生产未来发展要求,建立和开发融合智能控制技术、专家系统、网络技术、现场总线技术的营养液检测与控制新型系统具有实际应用意义。
The advance of technology of detecting and controlling nutrient solution of soilless culture in controlled environment plant production system was introduced. Several technologies of detecting and controlling nutrient solution were discussed and compared. It was noticed that the main problems of present technologies were high cost, low reliability, and low intelligence, etc. In order to meet the demand to develop controlled environment plant production in future, it is of practically significance to establish and exploit a new system to detect and control nutrient solution by means of merging intelligent control technology, expert system, network technology and fieldbus technology together.
