Embodiment Construction

[0026] In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

[0027] In order to describe the technical solution of the present application and its effects in more detail, the following will first describe the CRS coding and PF_RING in detail.

[0028] CRS code

[0029] CRS coding is an improvement of RS code based on Vandermonde matrix. The complexity of RS coding algorithm is relatively high, and its decoding algorithm complexity is O(n 3 ). Compared with RS coding, the CRS coding method reduces the complexity of matrix inversion, and GF(2 w The elements in the) field are converted into a binary matrix, which simplifies the multiplication operation and the decoding algorithm...

Abstract

The invention relates to a power network unidirectional transmission device and system. The device comprises a first packet capturing and forwarding module, an encoding module, a decoding module and asecond packet capturing and forwarding module; the first packet capturing and forwarding module captures a data packet output by a network card in an external network host based on a PF _ RING mechanism; the encoding module performs CRS encoding on the captured data packet; the first packet capturing and forwarding module forwards the coded data to a one-way transmission channel of the power network based on a PF _ RING mechanism; the second packet capturing and forwarding module captures coded data output in the one-way transmission channel of the power network based on a PF _ RING mechanism; the decoding module carries out CRS decoding on the encoded data, the second packet capturing and forwarding module forwards the decoded data packet to a network card in an intranet host based on aPF _ RING mechanism, and the whole device efficiently achieves one-way data transmission of a power network on the premise that communication safety is ensured based on CRS encoding and PF _ RING.

Description

Technical field [0001] This application relates to the technical field of power grids, and in particular to a one-way transmission device and system for a power network. Background technique [0002] In the conventional power grid, the one-way transmission system of the power network only has a one-way transmission path, and there is no interactive control protocol. The fault-tolerant control of power data is a big problem. Regardless of the manual method, the redundancy check method or the dual-computer redundancy method, the traditional one-way transmission reliability strategy often has resource or rate restrictions, and the degree of reliability is not high. It faces transmission during high-speed transmission. Errors, congestion and continuous packet loss. [0003] Common power network transmission methods include the following: 1) Manual control strategy, generally formulate a private protocol for transmission, after the destination master station receives the message, it pa...
