The invention provides an Internet-based load short message prompting system and method. The system comprises: an on-site specific power transformer acquisition terminal, which acquires first load information in real time; a reception unit, which classifies the first load information and obtains second load information; an analysis unit, which distributes corresponding terminals for the second load information through analysis; a comparison unit, which compares the second load information with a preset safety threshold to generate a comparison result; a sending unit, which converts the comparison unit into short message information; and the terminals, which receive and display the short message information. According to the invention, load situations are monitored in real time, a damage rate of equipment is greatly reduced, and the cost is reduced.
