Abstract

The invention discloses a device early warning method and system based on temperature measurement and seasonal temperature difference. The method includes obtaining the direct measurement value of the device temperature at the current time point in a specific area and using it as the absolute temperature value Tdevice at the current time point of the device, and at the same time obtaining the current time point The predicted temperature value Tair at the point; use the difference between Tdevice and Tair to obtain the relative temperature rise value ΔT of the device at the current moment; compare Tdevice and ΔT with the preset absolute temperature threshold Tdevice(th) and the preset relative temperature rise threshold ΔTth, If any one of Tdevice and ΔT exceeds the corresponding threshold, an early warning is given; wherein, the time point is the minute time point or the hour time point.

Description

technical field [0001] The invention belongs to the field of equipment temperature monitoring, in particular to an equipment early warning method and system based on temperature measurement and seasonal temperature difference. Background technique [0002] In equipment monitoring and other fields, temperature measurement is an essential link. If the temperature of the point to be measured exceeds the warning value, the system will issue an alarm, make an emergency response, and notify the staff to take measures to avoid fires, explosions and other accidents. [0003] For the monitoring of equipment operating status in a specific area, the temperature measurement of the corresponding equipment will be affected by the temperature. For example: at the first time point: when monitoring the temperature of a certain equipment, the air temperature is A°C, and the measured value of the equipment temperature is B°C, then the The temperature rise of the equipment relative to the air t...
