摘要
针对电类传感器难以满足桥梁结构长期监测要求的问题,提出利用光纤光栅振动传感器对桥梁的振动状态进行监测,并通过理论和实验结果论证了方案的可行性。光纤光栅传感器在满足频率测量范围、温度适应范围等要求的同时,兼具抗电磁干扰、外形结构简单、布设方便、长期稳定性好等优势,具有良好的工程应用前景。
In order to solve the problem that the electricity sensor cannot meet the requirement of longterm bridge structure monitoring,fiber Bragg grating vibration sensor is applied to bridge vibration monitoring.The feasibility of the scheme is verified through theoretical and experimental results.Fiber Bragg grating vibration sensor can fully meet the requirement of frequency measurement range and temperature.Meanwhile,it also has advantage of anti-electromagnetic interference,simple structure,convenient setting and good stability,which is conducive to the actual engineering.
