Description

1. Technical field: [0001] The invention relates to a structural health monitoring system, in particular to a multi-channel integrated scanning system for controlling a piezoelectric excitation-sensing network to realize structural health monitoring. 2. Background technology: [0002] The basic idea of ​​structural health monitoring is to integrate sensors, signal information processing components, and even drivers, controllers, and structural materials, so that structural materials can sense their own health status, diagnose their own safety, and even repair their own damage and adjust their own state. In this way, the function of the structure can be greatly enhanced, the safety and reliability of the structure can be improved, the maintenance cost of the structure can be reduced, and the service life of the structure can be prolonged. [0003] The structural health monitoring method based on active monitoring technology is a typical and effective hot research method. Its...
