This product is an online monitoring system for icing on transmission lines. Through high-precision sensing, edge computing, and Internet of Things technologies, it realizes real-time collection of data such as wire tension, inclination, meteorology, and images 24 hours a day, 7 days a week, and intelligently calculates the icing thickness. The system has a hierarchical automatic early warning function, providing a scientific basis for ice melting decision-making and operation and maintenance scheduling. It replaces passive response with active defense, helping the power grid operate safely and stably in severe cold and extreme environments.
