Abstract

The safe early-warning system for roof spatial latticed structure of Wuhan Natatorium is composed of sensing subsystem, database and administration subsystem and safe early-warning identification subsystem, which is automatic operation by system integration technique. According to the characteristics and service environment of roof spatial latticed structure of Wuhan Natatorium, the two key techniques are proposed; one is assessment structural key rods´ work status by data-acquisitions from strain gauges, another is detection firn thickness on the roof by fuzzy pattern identification method. The results of safe early-warning are displayed clearly by friendly interactive interface. The system operating satisfactorily demonstrates the efficient of safe early-warning system.
