NFC (Near Field Communication) technology-based intelligent substation optical cable label system

Abstract

The invention provides an NFC (Near Field Communication) technology-based intelligent substation optical cable label system which comprises an NFC intelligent label generation device, an NFC electronic label and an NFC intelligent label analysis device, wherein the NFC intelligent label generation device comprises a label file generation module and a first NFC card reader; the label file generation module is used for generating an intelligent label file; the first NFC card reader interacts with the NFC electronic label in an NFC wireless way and writes the intelligent label file generated by the label file generation module into the NFC electronic label; the NFC intelligent label analysis device is used for acquiring intelligent secondary equipment or optical fiber loop information by reading the intelligent label file in the NFC electronic label, matching the acquired intelligent secondary equipment or optical fiber loop information with analyzed SCD (Substation Configuration Description) data and then displaying the intelligent secondary equipment information and input and output of intelligent secondary equipment in a graphical way. According to the NFC technology-based intelligent substation optical cable label system, the personnel engineering construction and operation and maintenance efficiency of an intelligent substation secondary technology can be improved.

Description

technical field [0001] The invention relates to the technical field of smart substations, in particular to a smart substation optical cable labeling system based on NFC technology. Background technique [0002] Compared with conventional substations, smart substations have the technical advantages of signal digitization and transmission network. Optical signals are used for data transmission, and optical fibers replace most of the cables in the whole station. The design of the secondary circuit principle of the smart substation is changed to the optical cable connection diagram and the substation configuration description SCD (Substation Configuration Description) file expression. Sampling values ​​and protection control signals are all digitally coded and transmitted by optical fiber. There is a "one-to-many" relationship between the physical medium and the signal. Dozens of different information are transmitted simultaneously in one fiber core, while the optical fiber cabl...

Problems solved by technology

Sampling values ​​and protection control signals are all digitally coded and transmitted by optical fiber. There is a "one-to-many" relationship between the physical medium and the signal. Dozens of different information are transmitted simultaneously in one fiber core, while the optical fiber cable uses the cable number plate or Conventional smart labels only describe the starting point, end position and cable number of the optical cable, and the information that can be described is relatively simple

Debugging and operation and maintenance personnel often need to consult SCD files and optical cable contact diagrams alternately when checking and troubleshooting or troubleshooting; construction personnel also need to read the optical cable contact diagrams to input one by one when printing smart labels, which is cumbersome and inefficient.
