摘要
利用远程监测技术实时对建筑结构进行健康诊断和监测,对于保证生命财产安全、延长既有建筑物的使用寿命、有效降低建造成本具有显著作用。但远程监测系统通常都暴露于严苛的服役环境,实测中时有报错情况发生。建筑结构安全诊断的有效性依赖于监测系统的可靠性。为验证监测系统可靠性,设计了一个试验架进行对比试验。结果表明,外部环境稳定时,远程监测结果真实可靠。但监测系统内局部温度变化等外部条件变化时,会对监测结果产生一定影响。
Using remote monitoring technology to diagnose and monitor the health of building structures in real time plays a significant role in ensuring the safety of life and property,prolonging the service life of existing buildings and effectively reducing the construction cost.However,the remote monitoring system is usually exposed to the harsh service environment,and errors are often reported during the actual measurement.The validity of building structure safety diagnosis depends on the reliability of monitoring system.In order to verify the reliability of the monitoring system,a test frame is designed for comparative test.The results show that the remote monitoring results are true and reliable when the external environment is stable.However,when the external conditions such as local temperature change of the monitoring system change,the monitoring results will be affected to a certain extent.
