摘　　要：室外消火栓放水、低压、超压等会影响救援取水功能,为监测其非安全状态,采用数据滤波处理技术,基于一维压力数据,实现压力均值、压力差值、压力方差、压力方差增长率等高阶多维扩展,提出一种室外消火栓状态综合特征提取模型;通过采样频率、滑动滤波窗口宽度等条件组合优化,采集不同条件下压力数据,训练拟合模型参数;将模型应用到综合信息采集智能终端装置并安装在室外消火栓动态信息化监测系统中运行测试。结果表明:该模型能够准确判断室外消火栓放水、低压、超压状态,提升室外消火栓动态信息化安全管理水平。In order to monitor non-safety status of outdoor fire hydrant,such as water discharge,low pressure,overpressure,etc.,which affect normal use of rescue water intake function,data filtering processing technology was adopted,based on one-dimensional pressure data,high-order multidimensional expansion of pressure mean value,pressure difference,pressure variance and pressure variance growth rate were carried out,and a comprehensive feature extraction model of outdoor fire hydrant status was proposed.Through combination optimization of sampling frequency and sliding filter window width,pressure data under different conditions were collected,and fitting model parameters were trained.Model was applied to integrated information acquisition intelligent terminal device and installed in outdoor fire hydrant dynamic information monitoring system.The results show that model can accurately judge status of water discharge,low pressure and overpressure,and improve dynamic information safety management level of outdoor fire hydrant.
