沧州铁狮子健康监测数据采集系统的研究与应用

Research on and application of a data acquisition system for monitoring structural health of the Cangzhou Iron Lion

沧州铁狮子是世界上现存的最大铸铁狮子,其重要地位和所处的环境要求必须对其健康状况进行实时地监测和预警。针对其基础组成部分一沧州铁狮子健康监测数据采集系统进行了研究开发,首先分析了铁狮子传感器选型的影响因素并结合传感器自身的适用标准进行了具体的选型,然后进行了基于所选定传感器的硬件系统设计,运用Labview平台结合沧州铁狮子自身特点开发了一套采集软件系统,形成了一套完整的基于虚拟仪器技术的沧州铁狮子健康监测数据采集系统,最后成功将该系统应用于沧州铁狮子结构健康监测系统测试试验,证明了本套系统可为将来沧州铁狮子健康监测系统的实现提供重要支持。

The Cangzhou Iron Lion is the largest cast iron lion in the world. Its importance and environmental setting necessitate a system for on - site monitoring and early warning. The data acquisition system that comprises a major component of the health monitoring system for the Cangzhou Iron Lion is described. First, the sensors used for the Cangzhou Iron were chosen based on the performance factors and characteristics of different sensors. Then, a hardware system was designed for the chosen sensors. Software was developed by using Labview as the platform, and focused on the Cangzhou Iron Lion＇s special requirements. A complete data acquisition system based on virtual instrument technology was set up. Finally, experiments were done which showed that the data acquisition system could be applied to monitor the Cangzhou Iron Lion, which suggested that the developed system could support the realization of a future data acquisition system for monitoring the health of the Cangzhou Iron Lion.
