摘　　要：电解质多组分的在线检测是一项具有挑战性的课题,是生物工程、设施农业和环境检测等多个领域的关键技术之一。文章针对营养液成分的在线检测,根据机理分析,利用各离子成分之间的相关性,提出了一种虚拟离子电极,并进行了详细分析。虚拟离子电极采用径向基函数网络予以算法实现。文中提出的方法可以克服目前离子电极的限制,实验结果也验证了本方法的有效性。Electrolytes multiple components detection is a challenge project, and it is also one of the key technologies in many fields, for example, biology engineering, factory greenhouse and environment monitoring, etc. According to the relativity among the ions, this paper has presented a virtual ion electrode for one-line detection of the nutrition solutions components through the mechanistic model analysis. The multi-sensor data fusion based virtual ion electrode has been analyzed in details. Radial basis function network is introduced to implement the virtual ion electrode. This method may overcome the ion electrodes limitations. The results have shown that this method is effective.
