The system acquires temperature, humidity, and clock information, packages the data according to a standard protocol, and finally uploads the data to the local server via a wireless transmission module.

6. The method for measuring electrical parameters of natural icing of atmospheric structures as described in claim 5, characterized in that: The ice layer dielectric constant measuring device also includes a cylindrical electrode that rotates at a low speed during icing, and the icing direction does not change frequently, so that the final icing shape of the cylindrical electrode is a cylindrical ice layer.
