Design and implementation of optical cable label system for smart substation based on QR code
Lei Gao, Yu Liu, Yubo Yuan, Xiaokun Wang · 2015
The conventional optical cable labels in smart substations contain too little information to support operation or maintenance. To solve this problem, this paper introduced a QR (Quick Response) code system for labeling and identification of optical cable labels in China's smart substations. The label format is specified for three kinds of cables, and the implementation methods of generation module and identification module are also stated. The generation module can provide design drawings of secondary system, QR code labels and database for handheld terminals. The identification module can quickly identify the optical cable by scanning the QR code and show its physical connection and virtual circuit to users. In that way, scan-and-read for signal circuits is achieved, which improves the efficiency of commissioning, operation and maintenance work in smart substations.
