Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] Aiming at the area where the power optical fiber is laid to the station area, the present invention proposes a method for integrating the power line to extend the optical fiber to the local area and short-distance communication. Through the power line communication (Power Line Communication, PLC) technology, that is, in the power service information transmission channel The method of adding power line communication equipment extends the coverage of the optical fiber in the station area to the local information aggregation node, makes full use of the power’s own optical fiber and wired communication resources such as power lines, and solves the unstable communication status of wireless network coverage and the lack of public network lease information. Security, unmanageable network, and fixed annual rental fees, through fiber optic extens...

Abstract

The invention discloses a method, a device and a system for transmitting power business information, and relates to the technical field of power communication. The method, the device and the system for transmitting the power business information are mainly used for solving the problems of bad business quality, data safety and instantaneity when a wireless public network is applied to perform the power information transmission. The main technical scheme of the method, the device and the system for transmitting the power business information is: a sending party of the power business information receives power business information sent by a local information aggregation node, modulates and demodulates the power business information, and couples the power business information after performing the modulation and demodulation treatment to a power line for transmission; a receiving party of the power business information decouples and receives the power business information coupled to the power line for transmission, modulates and demodulates the power business information obtained through decoupling, and sends the modulated and demodulated power business information to a zone area information aggregation node, so that the zone area information aggregation node can send the modulated and demodulated power business information to a main power business station through an optical fiber. The method, the device and the system for transmitting the power business information are mainly applied to the process of transmitting the power business information.

Description

technical field [0001] The present invention relates to the technical field of electric power communication, in particular to a method, device and system for electric power business information transmission. Background technique [0002] In the current information communication network supporting the smart grid, there are generally two levels of information transmission. The information transmission includes the information transmission of the remote channel between the business master station and the local information aggregation node, and the information transmission between the local information aggregation node and the power terminal. Information transmission on local channels. Among them, the communication technology used in the information transmission part of the remote channel mainly includes three communication methods: optical fiber, wireless public network and wireless private network, among which the wireless public network is the most widely used; Communication...
