Abstract

A power carrier communication system supporting long-distance transmission, including a first power carrier communication module, a second power carrier communication module, a power carrier filtering device, and a power carrier modulation device; the first power carrier communication module and the second power carrier communication module They are connected to each other, and contain a power detection module and a power carrier communication signal amplification module inside. Both the first power carrier communication module and the second power carrier communication module are connected with a power carrier filter device, and each power carrier filter device is connected with a power carrier modulation equipment. Optionally, when there are multiple ports, a combiner or splitter needs to be introduced to connect signals of multiple input ports or output ports. The present invention introduces the power carrier communication signal relay equipment, because the application processing module structure can be removed, and only the signal processing circuit of the communication processor can complete the power carrier signal relay, the system design is simpler, the cost is reduced, and the power consumption is reduced. Also lower.

Description

technical field [0001] The invention belongs to the technical field of power line carrier communication, in particular to a power carrier communication system supporting long-distance transmission. Background technique [0002] The closest existing technology to this technology is the power line carrier communication technology. In the power carrier communication technology, the power carrier communication signal for transmitting data is modulated onto a 0-50MHz high-frequency modulation signal, and this high-frequency modulation signal is superimposed on the power line The 50Hz low-frequency AC power signal constitutes a power carrier signal, which is transmitted to other terminals of the power system along with the power cable. [0003] The main application scenario of the traditional power carrier communication technology is the power modem to access the Internet. The indoor Internet terminal modulates the signal into a power carrier signal through the power modem, and tr...
