摘要：
The present invention relates to a system for monitoring a switchgear, the system comprising:
- an infrared camera;
- a processing unit; and
- an output unit.
The infrared camera is configured to acquire an infrared image of the switchgear. The processing unit is configured to convert the infrared image into a binary image. Pixels in the infrared image having a temperature equal to or above a first threshold value are given the same first value. Pixels in the infrared image having a temperature below the first threshold value are given the same second value. The processing unit is configured to implement a Siamese neural network to determine if a hot spot exists in the infrared image. The determination by the Siamese neural network comprises analysis by the Siamese neural network of the binary image and a reference binary image. The reference binary image was generated from a reference infrared image of the switchgear or of a reference switchgear. Pixels in the reference infrared image having a temperature equal to or above a second threshold value were given the same first value. Pixels in the reference infrared image having a temperature below the second threshold value were given the same second value to generate the reference binary image. The output unit is configured to output an indication of a fault in the switchgear on the basis that a hot spot has been determined to exist in the infrared image.
