[0053] Install:

[0054] Fix the connection base 1 to the bottom of the drone with bolts or buckles to ensure a secure installation.

[0055] The connecting base installs the rainproof heat dissipation pod 3 at an appropriate position through the connecting arm 2, so that the infrared thermal imager 4 faces the observation target area of ​​the UAV.

[0056] Debug and run:

[0057] The infrared thermal imager 4 is activated through the control system of the UAV to collect real-time images.

[0058] Through the coordinated work of the sensor module 4 and the control module 7, the collected infrared image data is transmitted to the ground station for image processing and analysis.

[0059] Maintenance and care:

[0060] Regularly check whether there is dust or foreign matter on the surface of the heat sink 321 to ensure that the heat dissipation efficiency is not affected.

[0061] Check whether the flashing plate 31 is damaged or loose, and replace or reinforce it if necessary.

[0062] After long-term use, reapply thermal grease to ensure good heat conduction performance.
