Carrier communication system special for low-voltage power line

Abstract

The invention discloses a carrier communication system special for a low-voltage power line and belongs to the carrier communication field. According to the carrier communication system special for the low-voltage power line, a double-line parallel module is arranged to provide a standby signal transmission line for the carrier communication system; in a signal transmission process, when a signalanalysis module analyzes and determines that the signal transmission deformation of a vertical branch line is relatively large, a carrier terminal controls a self-breaking mechanism to be inflated anddeformed so that the vertical branch line is disconnected from the transmission line; a pre-expanding bag is broken through a pre-splitting pull rope so that a winding branch line is conducted with the transmission line, so that the conduction of the standby signal transmission line is realized, the corresponding communication information with small interference is obtained, the situation of information transmission errors caused by serious deformation in the signal transmission process is effectively avoided, and the correctness and efficiency of signal transmission of the carrier communication system are effectively improved.

Description

technical field [0001] The invention relates to the field of carrier communication, more specifically, to a carrier communication system dedicated to low-voltage power lines. Background technique [0002] Low-voltage lines refer to power lines with a rated voltage of 1kV and below. Low-voltage lines include low-voltage overhead lines, low-voltage overhead insulated lines, low-voltage cable lines and indoor distribution lines, which are used to directly transmit electric energy to low-voltage electrical equipment and are an important part of the low-voltage power distribution system (see low-voltage power distribution). The low-voltage line can be connected from the public low-voltage distribution network and lead out through the low-voltage power distribution room; it can also be led out from the low-voltage power distribution device in the user-provided transformation and distribution room. [0003] Carrier communication is a telephone multiplex communication system based ...
