摘　　要：针对目前对无线测温系统偏重系统设计、缺乏对告警研究以及无法了解设备运行状态的现状，提出了5种利用温度数据进行设备告警的方式，结合各告警方式的自身特点提出了不同的阈值整定模式，并对其中2种告警方式提出采用浮动阈值的形式，最后针对各告警方式提出相应的算法。该系统在变电站现场上的成功运行，证明了告警方式及算法的可靠性。Under the condition that too much emphasis on the system design, but lack of alarm information and inadequate information of the equipment＇s operating status in the existing wireless temperature measuring sys tern, 5 equipment alarming methods using temperature are proposed, and different threshold tuning modes are given accordingly. Floating threshold modus is adopted in the 2 alarming methods. Finally, the corresponding algorithms are proposed based on the 5 different alarming methods. The reliability of the alarming methods and the algorithms are proved in the on site successfully operating of substations.
