【摘要】 以嵌入式系统为核心,提出一种基于Kalman滤波的氧化还原电位测量传感器。该传感器采用去极化法对铂电极和银-氯化银电极进行处理,可以快速准确实现对氧化还原电位的测量。此外还采用自组织无线网状网,实现即放即用的灵活网络测量方式,非常灵活地加入或撤出整个测量网络系统,同时具备存储和USB以及CAN总线通讯功能。采用Kalman滤波算法对测得的数据进行处理,提高测量的精度和数据的可靠性。更多还原

【Abstract】 This paper introduced an Oxidation Reduction Potential network sensor based on Kalman filtering,which based on embedded system.This sensor uses depolarization measure to dispose platinum electrode and Ag-AgCl electrode,and it can detect Oxidation Reduction Potential(ORP) fast and exactly.Also,this senor uses wireless mesh network to realize flexible network measure.So it can arbitrary add and delete sensor node in the whole detection system.Furthermore,it has store and communication of USB and CAN bus.The ORP network sensor adopted Kalman filter algorithm to process the data measured by the ORP pole,thus the precision and reliability of measurement are enhanced.更多还原
