The invention provides a switch cabinet temperature monitoring method and system, and belongs to the technical field of power monitoring. The method comprises the following steps: firstly, performing temperature measurement and image acquisition on internal parts of the switch cabinet to obtain temperature data and a corresponding thermal imaging image; secondly, filtering and calibrating the temperature data to obtain standard temperature data of each component; inputting the thermal imaging image into a detection network for feature extraction to obtain an identification result; according to the identification result, analyzing the temperature of the part area to obtain thermal imaging characteristics; and finally, a temperature inversion model is established in combination with the standard temperature data and the thermal imaging characteristics, and the future temperature state of the internal components of the switch cabinet is predicted. According to the invention, real-time and accurate monitoring of
