Embodiment 1

[0064] Embodiment 1 of the present invention provides an information processing method, which is applied to the first concentrator, and the first concentrator belongs to the first platform, figure 1 A schematic flow chart of the method is shown, and the method may include:

[0065] S101: Receive and demodulate crosstalk information.

[0066] In this embodiment, when the first concentrator receives a piece of information, it will identify whether the received information belongs to its own station area, that is, whether it belongs to the first station area. If the received information does not belong to its own station area, then the first station The area judges this information as crosstalk information.

[0067] The crosstalk information in this embodiment may include: indication information of the station to which the crosstalk information belongs, the indication information of the station to which the crosstalk information belongs may be the station identifier of the stati...

Embodiment 2

[0077] Embodiment 2 of the present invention provides an information processing method, which is applied to the first concentrator, and the first concentrator belongs to the first zone, figure 2 A schematic flow chart of the method is shown, and the method may include:

[0078] S201: Receive and demodulate crosstalk information.

[0079] In this embodiment, when the first concentrator receives a piece of information, it will identify whether the received information belongs to its own station area, that is, whether it belongs to the first station area. If the received information does not belong to its own station area, then the first station area This information is judged as crosstalk information.

[0080] The crosstalk information in this embodiment may include: indication information of the station to which the crosstalk information belongs, the indication information of the station to which the crosstalk information belongs may be the station identifier of the station t...

Embodiment 3

[0088] Embodiment 3 of the present invention provides an information processing method, which is applied to the first concentrator, and the first concentrator belongs to the first zone, image 3 A schematic flow chart of the method is shown, and the method may include:

[0089] S301: Receive and demodulate crosstalk information.

[0090] In this embodiment, when the first concentrator receives a piece of information, it will identify whether the received information belongs to its own station area, that is, whether it belongs to the first station area. If the received information does not belong to its own station area, then the first station The area judges this information as crosstalk information.

[0091] The crosstalk information in this embodiment may include: indication information of the station to which the crosstalk information belongs, the indication information of the station to which the crosstalk information belongs may be the station identifier of the station to ...

Abstract

The invention provides an information processing method, a concentrator, a master station and a power-line carrier communication system. The information processing method comprises the steps: a first concentrator of a first station zone receives and demodulates crosstalk information, when the crosstalk information is correctly demodulated, a station zone where the crosstalk information belongs is confirmed, and when the condition that the crosstalk information belongs to a second station zone is confirmed, the crosstalk information is sent to the second station zone or the master station for information combination. User data information received by the concentrator in the station zone from a collector may not be demodulated correctly due to poor channel quality, however, when other station zone is interfered by the information in a crosstalk mode, the information may be demodulated correctly due to good channel quality and becomes useful information. According to the information processing method, the concentrator, the master station and the power-line carrier communication system, the correctly demodulated crosstalk information is used for compensating or correcting the user data information so that success rate of information collection is improved and communication reliability is increased.

Description

technical field [0001] The invention relates to the technical field of power line carrier communication, in particular to an information processing method, a concentrator, a master station and a power line carrier communication system. Background technique [0002] The power grid is a nearly natural physical network with a high penetration rate. However, the main function of the current power grid is to transmit electric energy. How to use the resource potential of the power grid to realize narrowband or broadband communication without affecting the transmission of electric energy, making it another communication after telecommunications, telephone, wireless communication, and satellite communication. Networking has been the research target of domestic and foreign scientific and technological personnel for many years. [0003] Power line communication is a communication method that uses the power grid as a channel to realize data transmission and information exchange. Sinc...
