Study on adaptive alarm for health monitoring of Heavy Haul Railway Bridges
The threshold alarm system for the health monitoring of heavy haul railway bridges is an important index for evaluating the health monitoring system of bridge.According to the characteristic of railway bridge response signal,the response signal is divided into two parts: train response and non train response.Automatic identification of train bridge by intermittent time series of monitoring data of the construction time,probability statistical distribution of monitoring in the process of running,the maximum probability of traffic in response to the reference value,and thus a bridge traffic peak response,the driving response reference value fitting and bridge monitoring temperature,and 95%confidence interval set as the upper threshold non Vehicular Response; the response peak of different train under the action of the upper limit of the 95%confidence interval as the threshold limit driving response,adaptive to heavy haul railway bridge health monitoring data of different temperature and train under the action of alarm.
