Abstract :
There exist corresponding relationships of state information between the suspension points of the maglev train. This essay carries on the statistics of monitoring data of all the suspension points, describes the distributed situation of the suspension points data frequently spotted in engineering practices, detects suspect values and abnormal values in the suspension system based on the steady estimator of general parameters, according to the detailed situation, conducts analysis and evaluation, carries out the present abnormal data and processing method of failures, provides protections to the safe operation of trains.
