Smart film crack monitoring method, which can be used for detecting initiation, length, width, shape, location, and propagation of cracks on real bridges, is proposed. Firstly, the fabrication of the smart film is developed. Then the feasibility of the method is analyzed and verified by the mechanical sensing character of the smart film under the two conditions of normal strain and crack initiation. Meanwhile, the coupling interference between parallel enameled wires of the smart film is discussed, and then low-frequency detecting signal and the custom communication protocol are used to decrease interference. On this basis, crack monitoring system with smart film is designed, where the collected crack data is sent to the remote monitoring center and the cracks are simulated and recurred. Finally, the monitoring system is applied to six bridges, and the effects are discussed.

Concrete Casting

By monitoring and controlling the temperature and stress of concrete in the process of mass concrete casting, the temperature stress can be reduced effectively. In response to problems of traditional temperature and strain monitoring method, a new kind of distributed temperature and strain monitoring system based on mobile-agent and GPRS had been proposed. And also this system design a data integration middleware based on mobile-agent which verify the validity of the middleware through the experiment on Genomote nodes of network. Through GPRS network, remote data monitoring center receives data packets of temperature and strain of the concrete. The real-time display function of temperature and strain parameters was achieved by PC software programmed by Labview. The experiment show that the temperature acquisition value and the standard temperature error is within the scope of the permit (<1°C) and the system is stable, reliable for the needs of the remote monitoring.
