Abstract

The paper established the whole system for stress monitoring and safety assessment of metal structure aimed at kinds of cranes, based on LabVIEW software platform. Introduced function and composition of each subsystem in detail. The system consists of data acquisition, signal analysis and processing, data storage, historical data inquiry, safety assessment, critical security warning and estimation of fatigue life. The system adopted the wireless transmission method at the same time. As a result, feasibility of the system was proved by the case applied and it offered a convenient method for monitoring. The successful application of stress monitoring and safety assessment in the metal construction of large crane equipment makes foundation for its application in projects, which has great practical value.
