PRACTICAL STRUCTURAL HEALTH MONITORING SYSTEM OF LOW-COST SMART SENSORS WITH WIRELESS NETWORK

摘要：

The monitoring system for RC structures is presented adopting two types of smart sensors which translate the measurements to the damage indices and transmit them in the minimum amount of data. The developed smart AE (acoustic emission) sensor is useful for local monitoring finding the crack of concrete, and new smart VA (vibration analyzing) sensor is used for global monitoring by detecting the change in dynamic properties of the building structure. The reduced amounts of data are sent via wireless network using the standard ZigBeeR, which provides the reduced consumption of electricity.
