基于状态信息的区域自动气象站供电和通信故障预判方法研究

Research on power supply and communication fault prediction method on regional automatic weather station based on status information

文章以天津市50个区域站状态数据为基础,对其太阳能板充电电流、蓄电池压降速度、蓄电池放电电流、蓄电池电压和通信信号强度数据进行分析,形成了“两级告警”的供电和通信故障预判方法。该方法通过历史极值设置阈值,并根据未来状态数据和站点状态对预警进行修正,能够实现区域站供电和通信故障的提前告警,为预防性运维在自动气象站及气象装备中的应用提供借鉴思路。软件应用结果表明,该方法能够及时发出告警,提醒值班人员查看并关注站点状态,为区域站故障预测提供支持。

Based on the state data of 50 regional stations in Tianjin, this paper analyzes the charging current of solar panel, the voltage drop speed of battery, the discharge current of battery, the voltage of battery and the intensity of communication signal, and forms a "two-level alarm" power supply and communication fault prediction method.This method sets the threshold through the historical extreme value, and corrects the early warning according to the future state data and station state.It can realize the early warning of power supply and communication faults in regional stations, and provide reference for the application of preventive operation and maintenance in automatic weather stations and meteorological equipment.The software application results show that the method can send out alarms in time, remind the on-duty personnel to check and pay attention to the station status, and provide support for regional station fault prediction.
