Description

technical field [0001] The invention relates to a composite voltage carrier communication system, which belongs to the technical field of power carrier communication. Background technique [0002] Power carrier technology is a unique communication technology for power systems. Power carrier has the advantages of simple networking, investment saving, stability and reliability, and is widely used in power systems. Chinese patent 201020243425.2 discloses a power composite voltage carrier communication structure, which can directly convert from 220-400V low-voltage lines to 10kV-220kV lines for data communication without relying on other communication media other than power lines. The applicant found in the test that most of the outdoor re-voltage carrier machines and indoor re-voltage carrier management machines used in this structure use GPRS communication modules or Ethernet interface devices for data transmission in the existing power communication technology, and the disadv...
