Research on health monitoring technology for ancient building based on WSN

针对如何利用信息技术有效保护古建筑,提出一种运用多维信息融合技术实现对古建筑的实时状态进行自动监测的传感器网络体系架构,包括物理感知层、网络传输层、服务分析层和管理决策层4个层次,并对体系中各层次的技术方案进行相应的设计。其中,为实现对古建筑的各项参数进行准确地采集、预处理和传输,设计古建筑监测无线传感网。另外,为便于监测数据的保存和分析,建立古建筑健康状态数据库。为更准确地判定古建筑现状的健康程度,为管理部门提供决策依据,提出结合多源信息融合理论和预测算法对古建筑健康状态进行深度分析的方法。该体系已应用在相关古建筑的实际监测中,可以充分体现其便捷、实用、可靠性高的优势。

This paper presents a sensor network architecture for automatic monitoring on real-time status of ancient buildings, which is based on multi -dimensional information fusion technology, including physical sensing layer, network transport layer, service analysis layer and management decision layer. In addition, the technical plan at all levels of the system is designed in relevant aspects. Moreover , we have designed the ancient building monitoring wireless sensor network to achieve the accurate collection, pre-processing and transmission for the parameters of ancient building. Besides in order to facilitate the preservation and analysis of monitoring data, we have established the ancient building health status database. Furthermore, we have put forward a deep analysis method on the health status of the ancient buildings by combining the multi - source information fusion theory and the forecasting algorithm to determine the health degree of the ancient building more accurately and provide the decision-making basis for the management department. The system has been applied in actual monitoring of ancient buildings and it has superior performances such as convenience and high reliability.
