Embodiment Construction
[0083] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.
[0084] In order to solve the above technical problems, an embodiment of the present invention provides a space roof truss damage detection system, including: a laser transmitter, used to emit laser light to the target node; a laser receiver, used to receive the reflected light of the target node; The parameter calculation module is used to convert the optical signal received by the laser receiver into the low-order natural mode shape of the vibration of the space roof truss, and calculate the damage parameters of each unit of the space roof truss according to the low-order natural mode shape of the vibration of the space roof truss . Among them, the laser transmitter and laser receiver realize the corresponding functions based on the dynamic data acquisition system.
