HEALTH MONITORING SYSTEM
Intelligent health monitoring system of the long-span railway stayed requires the comprehensive knowledge of instrumentation, analytical and information processing technologies with the knowledge and experiences in design, construction, operation and maintenance of railway equipment for long-term monitoring the performance throughout its lifecycle. It is necessary to perform sensor-based structural monitoring for identifying the conditions in order to assure the structural safety and to evaluate the operational performance. The considerations for deploying a proper monitoring system are appropriate sensor instrumentation, robust signal acquisition, reliable signal processing, and intelligent signal and information processing. Sensor and hardware instrumentation, signal transmission, signal acquisition and analysis are schematically described mainly. Fire and gas sensors are used to protect entire train system. And for passenger safety, we are attaching a wireless RF system. With this advanced equipment, the exact dangerous spot is known with in less time.
