System Integration of Safe Early-Warning System Hardware for Roof Spatial Latticed Structure of Wuhan Natatorium

Considering the requirement of safe early-warning for roof spatial latticed structure of Wuhan Natatorium, according to determined monitoring key rods and position of latticed structure by civil engineer through stress analysis, the strain gauges placement and general frame of safe early-warning system are designed in the paper. Measurement principle and modifying project of strain gauges are analyzed in detail. Data-acquisitions communication system by wireless transmission is constructed. The system hardware integration has completed. Data analysis processing software employs database background affair processing method. Wireless data-acquisition software adopts multithreading technique and background serving technique. These are important roles in ensuring the whole safe early-warning system operation accurate and effective.
