将压电元件埋入混凝土构件中 ,形成敏感网络 ,可以无源、主动、不间断在线监测土木工程结构的动态特性。为了同时实现对结构静特性的监测 ,用相同的压电元在电激励下产生声振动 ,声波在结构中传播 ,结构的静、动态特性都将调制声传播 ,其它的压电元将声信号转换成电信号输出。压电机敏土木工程结构技术 ,充分利用了压电特性 ,可以实现结构的在线、不间断、主动以及无源监测 ,解决了土木工程结构监测中空间大范围分布、时效性、能耗限制的要求 Piezoelectric elements embedded in concrete components, the formation of a sensitive network, you can passive, active, uninterrupted online monitoring of the dynamic characteristics of civil engineering structures. In order to monitor the static characteristics of the structure at the same time, the same piezoelectric element is used to generate acoustic vibration under the electric excitation. The acoustic wave propagates in the structure. The static and dynamic characteristics of the structure all transmit the modulated sound. The other piezoelectric elements transmit the acoustic signal Converted into electrical signal output. Piezoelectric civil engineering structure technology, take full advantage of the piezoelectric characteristics, can achieve the structure of the online, uninterrupted, active and passive monitoring to solve the large-scale distribution of civil engineering structure monitoring space, timeliness, energy consumption restrictions
