Design method and system for optical fiber circuit guided by graphics based on information flow direction

Abstract

The invention discloses a graph guiding optical fiber loop design method and system based on information flowing directions. The method comprises the following steps of obtaining basic information of intelligent devices to be configured; meanwhile, obtaining plug-in port information of the intelligent devices according a back plate drawing provided by an intelligent device manufacturer; obtaining the information flowing directions between the intelligent devices according to the design scheme requirements of an intelligent transformer station; drawing the information flowing direction between the intelligent devices according to the basic information of the intelligent devices, the plug-in port information of the intelligent devices and the information flowing directions; configuring an optical fiber loop according to the obtained information flowing direction between the intelligent devices; after the optical fiber loop connection, selecting a plurality of optical fibers to form each optical cable according to an optical cable plan, and numbering the optical cables; sequentially completing the optical fiber pairing and the optical cable planning in each information flowing direction; finally completing the optical fiber loop configuration work of the whole intelligent transformer station. The problems of insufficient design depth, indirect design result display and the like can be effectively solved.

Description

technical field [0001] The invention relates to a method and a system for designing an optical fiber circuit guided by a graph based on information flow direction. Background technique [0002] The smart substation adopts the IEC 61850 standard system, and its communication mode is different from that of conventional substations. The hard-wired transmission of analog signals is replaced by digital signals transmitted by optical fibers, and a large number of cables are replaced by a small number of optical fibers, which leads to a large number of optical fibers in the design drawings. 1. The design drawing of optical cable connection. Although the connection between the optical fiber and the smart device can be expressed in the conventional design drawing, the following problems still exist in the specific construction: [0003] (1) The on-site optical fiber is not directly connected to the smart device, but is first connected to the "optical distribution" terminal, and then ...
