Embodiment Construction

[0024] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings of this specification.

[0025] The present invention proposes a method for testing power line carrier communication. The carrier signal and noise on the power line are coupled into a comparator. By comparing with a preset comparison threshold, the state of the carrier signal and the state of the noise can be indicated. Efficient carrier sounding and amplitude evaluation in the field. Specifically, the method of the present invention includes: first performing frequency selection and coupling processing on the carrier signal and noise on the power line, and then performing full-wave rectification processing to obtain the peak value of the carrier signal; sending the peak value of the carrier signal to a comparator, and The comparison threshold is compared; the comparison result is used to drive the indicator light to indicate the sta...

Abstract

The invention discloses a method and device for testing power line carrier communication. The method for testing power line carrier communication comprises steps of performing frequency selection andcoupling processing on a carrier signal and noise on a power line, performing full wave rectification processing to obtain a carrier signal peak value, transmitting a peak value of the carrier signalto a comparator to compare with a preset comparison threshold value, and using a comparison result to drive an indication lamp in order to indicate a state of a carrier signal and a noise state. The method and device for testing the power line carrier communication can provide great convenience for laying and expansion of a power line carrier communication network.

Description

technical field [0001] The present invention relates to communication auxiliary equipment, in particular to power line carrier communication auxiliary equipment. Background technique [0002] PLC (power line carrier communication, power line carrier communication) is a communication technology that uses power transmission lines as a communication carrier. Since the power transmission line has a very strong support structure and more than two transmission lines are erected, it is economical and reliable to use the transmission line to transmit the power frequency current and transmit the carrier signal at the same time. At present, PLC is widely used in smart meter reading of electric energy meters, power consumption management, smart home, access control security and other occasions, and it is a unique communication method preferred by the power sector. [0003] PLC is a means of using the existing low-voltage distribution network as a transmission medium to realize data tr...
