Abstract

The invention discloses a power line carrier communication transmission device. The device is composed of a DC power supply, first to fourth capacitors, a first variable capacitor, a second variable capacitor, a first transformer, a second transformer, a first inductor, a second inductor, a resistor and an intermediate frequency amplifier. Compared with the prior art, power line carrier communication signals are subjected to three-time amplification and three-time filtering, efficient signal amplification is achieved while an efficient anti-interference state is achieved, interference signalsbrought by power cables can be filtered out, communication signals can be amplified, the quality of the communication signals is improved, and application and popularization value is achieved.

Description

technical field [0001] The invention relates to a power communication processing device, in particular to a power carrier communication transmission device. Background technique [0002] Power line carrier communication is a power system communication in which the transmission line is used as the transmission medium of the carrier signal. Since the power transmission line has a very strong support structure and more than 3 conductors (generally there are three-phase good conductors and one or two overhead ground wires), it is economical to use the power frequency current to transmit the carrier signal at the same time as the transmission line And very reliable. This kind of comprehensive utilization has already become the unique communication means adopted by all electric power departments in the world. In the prior art, the power carrier communication signal has a long transmission distance, which leads to too weak signal reception, and the power cable has a certain inter...
