Power-line communication interference devices

Abstract

The invention relates to power-line communication interference devices and particularly relates to a plurality of devices which perform communication interference on facilities which use power lines for communication and belongs to the technical field of power-line communication, communication interference and interference resistance and information security. A device specifically includes a power-line interface, a DC power supply, a power-line coupling filter, a power amplifier and an interference signal generator. The invention also provides a power-line communication interference device with a power-line communication signal detection and analysis function, a processing and forwarding power-line communication interference device and a power-line communication signal short circuit / bypassing power-line communication interference device. The power-line communication interference devices are connected with power lines conveniently through forms of power-line insert ports, insert grooves and sockets and the like so that interference signals which interfere power-line communication are generated; an excellent interference effect is achieved through an extra-low interference power and electricity consumption quantity is low so that the power-line communication interference devices are especially suitable for being used in low-power-consumption inference application; and the interference mechanisms are simple in structure, low in realization cost and high in self-adaptive capability.

Description

technical field [0001] The invention relates to a power line communication interference device, in particular to a variety of devices for communication interference to facilities using power lines for communication, and belongs to the technical fields of power line communication, communication interference and anti-interference, and information security. Background technique [0002] Power line carrier communication is a technology that uses power lines to transmit communication signals to achieve information transmission. The communication signal processing system uses a power line coupling filter to connect to the power line to realize the transmission and reception of communication signals. The power line coupling filter realizes the strong electrical isolation between the communication system and the power line, and couples the transmission signal of the communication system to the power line to complete the output of the signal to the power line; at the same time, the f...
