Research of bridge health remote real-time monitoring and alarm

Costly bridge construction is closely related to people´s livelihood. Therefore, it is imperative to enhance the bridge health monitoring studies in order to ensure the rational design of the bridge, scientific conservation, safe and durable. ^[1] This paper makes a research on the bridge health assessment, damage detection theory and time series, advances that the raw data acquisition of bridge health monitoring systems should be processed into the characteristic parameters, so as to carry out further data mining and resource sharing. On this basis, a long-distance and real-time monitoring is developed and installed to monitor and alarm the situation of the railway bridge. The health monitoring systems generally include information acquisition, analysis, diagnosis, evaluation, feedback and safety. It enables the timely realization of the function of data acquisition by the curve and numerical methods, alarms are sent by cell phones or e-mail, historical information enquiries on a variety of ways and other functions are available. It has proved that the method and software have a great value to be promoted in regard to the long-range real-time monitoring of landslides, groundwater, and building construction.
