Problems solved by technology

[0006] The purpose of the present invention is to provide a HPLC carrier communication technology that can automatically test the line impedance, so as to solve the problem that the carrier communication technology proposed in the above background technology is not rigorous enough in the application, which easily leads to the detection of the carrier. In case of failure, such as stimulating and controlling the capacitor for a long time, the deviation of the regulation of the capacitor becomes larger and larger, which causes the control of the carrier wave to become worse and worse, which in turn affects the quality of communication.

Abstract

The invention relates to an HPLC carrier communication technology capable of automatically testing line impedance, comprising a carrier wave measurement module and an early warning module. The precision sub-detection modules are all electrically connected, the high-precision sub-detection module and the data retrieval module are electrically connected, the main detection module and the impedance data storage module are electrically connected, and the impedance The data storage module and the impedance data comparison module are electrically connected. The beneficial effects of the invention are: the HPLC carrier communication technology that can automatically test the line impedance is provided with an impedance data storage module, an impedance monitoring module and an impedance control module, and a monitoring signal is transmitted to the impedance monitoring module through the impedance detection module, and then passes through the impedance monitoring module. The data comparison module is used to analyze and compare the impedance data, and then the data is transferred to the impedance control module for monitoring and control operations.

Description

technical field [0001] The invention relates to the technical field of carrier communication, in particular to an HPLC carrier communication technology capable of automatically testing line impedance. Background technique [0002] Carrier communication is a telephone multiplex communication system based on frequency division multiplexing technology, which belongs to the standard of classic analog communication. [0003] Power line communication technology (Power Line Communication) appeared in the early 1920s. It is a means of realizing data transmission and information exchange by using the existing low-voltage distribution network as a transmission medium. When using power line communication to send data, the transmitter first modulates the data on a high-frequency carrier, and then couples it to the power line through a coupling circuit after power amplification. The peak-to-peak voltage of the signal band generally does not exceed 10V, so it will not cause adverse effe...
