摘要
Abstract
The monitoring results of tilt sensor in GSM-R tower monitoring system directly reflect the heeling state of the tower.Tilt sensor will inevitably be affected by the error caused by manual installation in the installation process,so the sensor should be corrected.In view of this,the paper used the DBSCAN algorithm to correct the tilt sensor instead of the mean value method,because noise data easily disturbs the mean value method.But the DBSCAN algorithm is very sensitive to parameters.Thus, the DBSCAN algorithm is proposed to take the place of traditional average calculation method to correct tilt sensor.Also,the DBSCAN algorithm is optimized to solve the parameter sensitivity.Experimental results show that optimized DBSCAN algorithm can effectively distinguish noises from data set.The optimized DBSCAN algorithm removes noises from the data set,and using the clustering results to calculate the steady-state centre offset of the tower which can correct the tilt sensor.In summary,it can apply to the requirements of correction of angle sensor.关键词
