摘要：
Active and passive monitoring technology based on Lamb wave is one of the hot points to research on structural health monitoring(SHM), but they have been applied independently. The analysis of the interaction and complementarity is conducted based on active and passive Lamb wave monitoring system, according to the advantages and disadvantages of the active and passive monitoring system. Their cooperative working mechanism is proposed by combining passive monitoring triggering with active intermittent scanning, setting active monitoring mechanism and fusing active and passive monitoring information. In addition, a hardware implementation of the active and passive integrated system is given and a software platform of real-time monitoring is built. The experimental results show that the active and passive cooperative technology and their system are well integrated with the active and passive monitoring information to improve the monitoring efficiency, monitor precision and reduce the system power consumption. © 2019, Editorial Department of JVMD.
