Problems solved by technology

[0002] The traditional alarm temperature threshold setting is manually set according to the allowable temperature range of the measured equipment components and the temperature range of the equipment components known from work experience, which cannot consider real-time environmental temperature factors and real-time power supply load factors, and there are set alarms. The temperature threshold is single and fixed, which is not accurate enough and the disadvantages of empiricism

Abstract

The invention discloses an alarm temperature threshold value judging and alarming method based on a passive wireless temperature measuring device. The method includes the steps of determining an alarmtemperature threshold value of the passive wireless temperature measuring device by taking the current environment temperature into consideration according to the historical collected temperature data of the passive wireless temperature measuring device and historical meteorological data of the place where the device is located, and conducting alarm prompt based on the temperature information data acquired by the current passive wireless temperature measuring device to achieve the purpose of rapidly finding out abnormal points and eliminating the potential risk. The method overcomes the defects that an alarm temperature threshold value of the passive wireless temperature measuring device is set by experience, is fixed and inaccurate, and that a common active temperature measuring device cannot work and cannot be replaced timely after power failure. The reliability of analyzing data sources is improved.

Description

Technical field: [0001] The invention relates to the technical field of equipment fault diagnosis in the electric power industry, in particular to an alarm temperature threshold judgment and alarm method based on a passive wireless temperature measuring device. Background technique: [0002] The traditional alarm temperature threshold setting is manually set according to the allowable temperature range of the measured equipment components and the temperature range of the equipment components known from work experience, which cannot consider real-time environmental temperature factors and real-time power supply load factors, and there are set alarms. The temperature threshold is single and fixed, which is not accurate enough and has the disadvantages of empiricism. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, provide a method that considers real-time environmental factors, and autom...
