Technical Field

The invention relates to a wireless temperature measurement monitoring device and a wireless temperature measurement monitoring method for a power system, which can monitor the temperature of equipment in real time.

Background

At present, the following methods exist for measuring the temperature of power system equipment:

(1) the contact type temperature labeling method roughly determines a temperature range by observing a color change thereof. This method has low accuracy, poor readability, inability to make quantitative and real-time measurements, and requires periodic visits by personnel.

(2) The non-contact infrared temperature measurement method utilizes an infrared measuring instrument to measure. The measuring method cannot accurately measure outdoor equipment under the condition of strong light, real-time detection cannot be achieved, in addition, an infrared imager cannot penetrate through a cabinet door to measure internal equipment, and the cabinet door must be closed when a switch cabinet runs, so that the infrared mode cannot be measured.

Based on the above analysis, the traditional temperature measurement system has the disadvantages that: full-automatic real-time monitoring cannot be realized; the temperature measurement is inaccurate and is easily influenced by the environment; the rule of continuous change of the equipment temperature cannot be obtained.
