With the development of science and technology, network connection is more and more important to daily life. Networks are playing an increasingly important role in everyday life. In many areas, however, there are areas where there is no network throughout the year. Especially in remote mountainous areas, the network assumes high costs without GPRS signal base stations and light infrastructure. At this time, network connectivity is particularly important. If the network connection is realized by a common method of erecting a new communication line, huge economic, time and labor costs are required. But in this place, with the strong support of national power infrastructure, there is probably a medium voltage power network. Therefore, it is considered that the network data is converted into the power line carrier data through the existing power line channel, and the power line topology of the network signal is realized, so that the network connection is extended to the non-network area.

A stable carrier link connection is established by establishing a medium voltage power line path between the networked area and the non-networked area. The content sent by the server/client connected with the slave computer module is transmitted to the medium-voltage carrier host computer module through the carrier link, and the host computer module analyzes the corresponding network message and uploads the network message to the client/server of the external network through the wired Ethernet port or the GPRS, so that complete network communication is realized.
Finally, it should be noted that: the above embodiments are merely illustrative of the technical solutions of the present invention, and those skilled in the art can modify or replace the specific embodiments of the present invention with reference to the above embodiments, and any modifications or equivalents without departing from the spirit and scope of the present invention are within the scope of the claims of the present invention as filed.
