摘要
针对铁路、桥梁、船舶等结构振动巡查中监测节点的自供电问题,研制了一种利用太阳能供电的振动信号无线传输模块。并对一悬臂梁的振动信号进行了室外发射与接收试验。试验结果与理论计算结果基本吻合,验证了设计方案的可行性。
In many engineering monitoring practices,such as railway and civil structure,the wireless sensor has a potential application.A wireless vibration sensor powered by solar cell instead of traditional chemical battery was developed in this paper.The architecture of the wireless sensor was presented.A wireless data transmission experiment of a cantilever beam's vibration was implemented and analyzed.The experimental result is accordant with the numerical calculation result.A multi-points communication between vibration monitoring nodes needs to be studied fourthly.
