摘　　要：为解决目前局域网下数据监控不精准的问题,提出基于局域网的气象数据智能监控系统。采用固定路径和移动路径交换帧线的冗余备份方式,设计局域网冗余结构实现备份。设计数据采集模块,通过轮询扫描监控模块,实现系统设备智能监控。根据关联规则确定告警信息的匹配程度,划分智能告警匹配度等级,计算告警信息权值,并寻找合适的阈值,减少监控系统中的虚警次数。通过构建监控误报抑制的迭代算法模型,对监控误报起到良好抑制效果。实验结果表明,该系统能精准监控气象数据,监控气温、气压数据误差为0,监控湿度和降水量最大误差分别为1%、20 mm。In order to solve the problem of inaccurate data monitoring under LAN,an intelligent meteorological data monitoring system based on LAN is proposed.The redundant backup mode of fixed path and mobile path exchange frame line is adopted,and the LAN redundant structure is designed to realize backup.The data acquisition module is designed,and the intelligent monitoring of system equipment is realized by polling and scanning the monitoring module.It determines the matching degree of alarm infor-mation according to association rules,divides the intelligent alarm matching degree level,calculates the weight of alarm informa-tion,and finds an appropriate threshold to reduce the number of false alarms in the monitoring system.By constructing the itera-tive algorithm model of monitoring false alarm suppression,it has a good suppression effect on monitoring false alarm.The ex-perimental results show that the system can accurately monitor meteorological data,the error of monitoring air temperature and pressure data is 0,and the maximum error of monitoring humidity and precipitation are 1%and 20mm respectively.
