摘　　要：为确保城市生命线的稳定运行,保障前端监测设备监测的准确性,开展现场校准工作。本文总结城市生命线前端监测设备的信息,并对现场校准方法和技术进行系统性分析。以燃气专项可燃气体监测仪和桥梁专项应变传感器为典型案例,分别应用数学拟合和软件方法进行修正。研究结果显示,经过数据修正的前端监测设备误差显著减小,校准后燃气、桥梁和供水专项合格率分别提高了15%、7.9%和33.3%,验证该现场校准技术的合理性和科学性。通过本次生命线前端监测设备的校准,提升城市生命线监测系统的准确性与稳定性。To ensure the stable operation of urban lifelines and guarantee the accuracy of front-end monitoring devices,on-site calibration work is conducted.This paper summarizes information on front-end monitoring devices for lifelines and systematically analyzes on-site calibration methods and techniques.Taking the gas-specific combustible gas monitor and the bridge-specific strain sensor as typical cases,mathematical fitting and software methods are applied for correction.The research results indicate a significant reduction in the error of front-end monitoring devices after data correction.Following calibration,the qualification rates for gas,bridge,and water supply specialties increase by 15%,7.9%,and 33.3%,validating the rationality and scientific nature of this on-site calibration technique.Through the calibration of front-end monitoring devices for lifelines in this study,the accuracy and stability of the urban lifeline monitoring system are enhanced.
