Description

technical field [0001] The invention relates to the field of data communication, in particular to a data transmission method and device for electric heating equipment. Background technique [0002] In the current urban power grid, electric heating equipment is built on a family basis, and the quantity is huge. Most of the currently existing demonstration systems combine public wireless networks and low-voltage power line carrier communication to build monitoring data transmission channels. When they are widely promoted, using public wireless networks as remote monitoring data transmission channels requires long-term payment of communication service fees, and there are still monitoring information security issues. . [0003] Aiming at the problem of high cost of the data transmission method of the electric heating equipment in the prior art, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a data ...
