Automatic equipment fault positioning and display method based on virtual reality technology

Abstract

The invention discloses a fault location and display method for automation equipment based on virtual reality technology, which includes a virtual connection of automation equipment, a fault location device and a visual display device. The device includes a real-time early warning device, a communication fault fast locator, a remote control failure locator, a remote signal jitter locator and a telemetry dead number locator, and the visual display device includes a control center display, a mobile intelligent terminal and a fault command vehicle. The invention realizes graphical display through the SCD virtual connection definer, predicts the state of the network or equipment through the fault location device, facilitates fault finding, makes remote control problems well-documented, and improves remote signal jitter and remote measurement dead number problem searching The efficiency of mobile smart terminals reduces communication errors, and the fault command vehicle improves the accuracy of reaching equipment fault points.

Description

technical field [0001] The invention relates to the field of substations, in particular to a method for locating and displaying faults of automation equipment based on virtual reality technology. Background technique [0002] At present, the intelligent substation automation system is configured, designed and debugged centered on the substation configuration description file SCD, and the concept of virtual connection is proposed to represent the internal virtual connection, external output and input virtual connection information of the equipment, and express it in the SCD. However, the content of the SCD file is huge, usually hundreds of thousands of lines, and the syntax is relatively complex, and it is difficult for design, debugging, and operation and maintenance personnel to understand directly when they lack knowledge of IEC 61850 and XML. For devices with two-way virtual connections between all parties, the existing fault location devices can only be used in fixed pla...

Problems solved by technology

However, the content of the SCD file is huge, usually hundreds of thousands of lines, and the syntax is relatively complex, and it is difficult for design, debugging, and operation and maintenance personnel to understand directly when they lack knowledge of IEC 61850 and XML. For devices with two-way virtual connections between parties, the existing fault location devices can only be used in fixed places, are inconvenient to carry, and do not have the function of automatic navigation to automatically bring personnel to the fault point
