Embodiment Construction

[0065] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0066] Such as figure 1 As shown, the receiving end (such as a site) of a traditional broadband power line communication system first uses a coupling transformer to couple the carrier signal from the low-voltage power line, filters out the out-of-band signal in the carrier signal through an analog band-pass filter, and uses an analog front-end to process the data Gain is automatically adjusted after analog-to-digital conversion, and further filtering is performed through a digital filter. The filtered data is calculated synchronously, and after synchronously finding the starting ...

Abstract

The embodiment of the invention provides a working frequency band determination method and device, a chip and a storage medium, belongs to the technical field of broadband power line communication, and solves the problems of low access efficiency and long access time caused by the fact that access is realized by traversing a working frequency band in the prior art. The method comprises the following steps: acquiring channel frequency responses of all subcarriers in a frequency band to be measured; obtaining a judgment threshold according to the channel frequency responses of all the subcarriers in the frequency band to be detected, and determining the working frequency band of the received signal according to a comparison result of the judgment threshold and the channel frequency responses of the subcarriers in the set frequency band, or determining the working frequency band of the received signal according to the channel frequency responses of all the subcarriers in the frequency band to be detected. And obtaining the average effective subcarrier intensity of each specified frequency band in the frequency band to be measured, executing a network access operation according to the average effective subcarrier intensity of each specified frequency band, and determining the specified frequency band successfully accessed to the network as the working frequency band for receiving the signal. The embodiment of the invention is suitable for a broadband power line communication access process.

Description

technical field [0001] The present invention relates to the technical field of broadband power line communication, in particular to a method, device, chip, electronic equipment and storage medium for determining a working frequency band. Background technique [0002] In broadband power line communication, the low-voltage power line high-speed carrier communication network uses the low-voltage power line as the communication medium to realize the low-voltage power user's electricity consumption information aggregation, transmission, and interactive communication network. Among them, during the access process of low-voltage power line high-speed carrier communication, the central coordinator sends a beacon frame containing management instruction information. After the station searches for the beacon frame sent by the central coordinator, it uses the work of the central coordinator The frequency band initiates an association request to the central coordinator, and data can only...
