A Data Fusion Algorithm on Data Preprocessing and Kalman Filter for Greenhouse Environment Monitor
摘要
Abstract
The greenhouse has the larger space,and the wireless nodes are vulnerable to the interference from the environment. The data collected by nodes are more volatile and many interference factors easily lead to packet loss. In order to enhance the reliability of wireless sensor neworks for the greenhouse monitoring,and improve the preci-sion of data fusion,a data fusion algorithm on data preprocessing and Kalman filter is proposed. Firstly,the data pre-processing method and Kalman filter is utilized to decrease the influence of abnormal data,then these data are sent to the cluster head and fused on the weighted data fusion algorithm with the state compensation strategy. The simula-tion is conducted on the greenhouse humidity, which shows that data preprocessing can significantly reduce data fluctuations, the amount of data transmission and the network energy consumption while improve the anti-interference ability of wirless networks. In addition,the weighted data fusion algorithm based on state compensation strategy can also significantly improve the fusion accuracy in the case of packet loss.关键词
