莱特准则改进算法的呼伦湖环境信息采集系统的设计
Design of Hulun Lake environment information acquisition system based on Letts criterion improved algorithm
摘要
Abstract
The environmental data collected by sensors and uploaded to the data center via ZigBee has been widely used in industrial application fields,but the information data collected by ZigBee may appear in outliers randomly due to the influences of hardware and external environment,which leads to the final data deviation or error. The improved Letts criterion algorithm to eliminate outliers is proposed in this paper. The algorithm can obtain the data needs to be kept by means of comparing the maxi⁃mum error and standard deviation,and finally eliminate the wrong data. By analyzing the system error data eliminated by the im⁃proved algorithm and comparing with the traditional Wright algorithm,the improved algorithm can enhance the accuracy of outliers elimination. The field test results show that the improved algorithm can get more accurate environmental information data com⁃paring with traditional algorithm.关键词
