| Abstract: | Life-index technology is an approach to implementing a lifecycle safety guarantee system and improving the level of predicting the potential damage of engineering structures.The life-index module,which obtains its load by sensing the load of structures in-situ and evaluates their safety level and remaining life,is developed to implement a lifecycle safety monitoring system.The module has been developed with field-bus technology and digital signal processors(DSP).The system architecture for remote monitoring of structural safety is proposed.The module can be used to monitor the damage in a local area of a structure while a module connected with field-buses can construct a distributed lifecycle monitoring network for large structures. |
