[0042] When in use, the staff first fixes the base 1 on the ground, then opens the cover 12 and uses the controller 11 to control the motor 306. When the limit block 4 on the round rod 303 slides in the limit groove 5, the round rod 303 can be prevented from rotating with the threaded rod 305. In this way, the threaded rod 305 can be driven by the motor 306 to drive the round rod 303 to move up and down, and the height of the dual-spectrum pan-tilt camera 201 is adjusted. When the monitored transformer is at a high height, the dual-spectrum pan-tilt camera 201 rises while shooting the transformer, which is suitable for transformers of different heights. The dual-spectrum pan-tilt camera 201 is used to shoot the transformer in real time. Specifically, the dual-spectrum pan-tilt camera 201 adopts a new generation of 12-micron uncooled infrared detector, which has a farther and clearer imaging and has the advantage of high-precision temperature measurement. Therefore, the temperature of the transformer can be intelligently detected without manual monitoring, and when the dual-spectrum pan-tilt camera 201 needs to be repaired, the staff can control the dual-spectrum pan-tilt camera 201 to descend and then perform maintenance, thereby reducing the danger of high-altitude operation.
