Abstract

The invention provides a dual-band power line carrier communication unit comprising a carrier MCU, wherein the carrier MCU is connected with an ammeter through a local interface; the carrier MCU is further connected with a signal output amplifying circuit and a signal input filter circuit; a signal coupling circuit is connected between the signal output amplifying circuit and the signal input filter circuit; and the signal coupling circuit is further connected with a power line. The problem that co-channel interference cannot be avoided during single band data transmission is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of low-voltage power line carrier meter reading, in particular to a dual-band power line carrier communication unit. Background technique [0002] At present, in the application of power line carrier meter reading, data transmission is mainly performed on a single frequency band, such as Neusoft carrier 270K / Dingxin carrier 421K, and the problem of co-frequency interference cannot be avoided during single-band data transmission. Contents of the invention [0003] In order to solve the above problems, the present invention provides a dual-band power line carrier communication unit, which effectively avoids the problem that co-channel interference cannot be avoided during single-band data transmission. [0004] In order to overcome the deficiencies in the prior art, the present invention provides a solution for a dual-band power line carrier communication unit, specifically as follows: [0005] A dual-band ...
