Abstract
The utility model discloses an oscillograph fault analysis platform. A communication module and an intelligent analysis module are arranged on a communication server. When power grid malfunctions, an oscillograph records and presents a fault wave file to the communication server, the wave file is received by the communication module, then the intelligent analysis module is invoked to analyze the wave file using the fault analyzer thereof, a report file is then integrated and generated and then delivered to a workstation after fault messages are distinguished, and the report file is finally displayed on the human-computer interface which runs on the workstation. An intelligent analysis module is installed on a server port of a recording networking and conducts real time analysis to the fault wave presented initiatively and shows the analysis result in the form of the report. Accuracy and speedability of the fault analysis are improved greatly with the help of the intelligent analysis. Manual labor and material resources are saved and working efficiency is improved due to the fact that the prior manual operation is replaced, and therefore the oscillograph fault analysis platform is beneficial to accident rush-repair work.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Structure is as shown in Figure 1 adopted in the record ripple networking of the utility model operation.Man-machine interface runs on the workstation, the demonstration with the result of issuing for the treatment of order, such as checking of the download of wave file, analysis and intelligent fault report etc., the order that issues is carried out and return results by communication server through switch, and wherein data server is used for the information such as stored waveform, report.
Include the oscillograph fault analysis platform of setting up by method of the present utility model in the communication server, as shown in Figure 2, be provided with communication module and intelligent analysis module in the communication server.Intelligent analysis module exists with the form of dynamic base, is called by communication module.When electrical network breaks down, oscillograph record ripple and on send the fault waveform file to communication server, this moment, communication module was temporarily stored in file under the communication module operation catalogue after receiving wave file in the TCP mode.If producer's user-defined format, be first COMTRADE 1999 forms of standard with producer's format conversion, then call intelligent analysis module, by the fault analysis algorithm in the intelligent analysis module this wave file is analyzed, determine such as information such as fault circuit, fault localization, fault types and integrate and generate report file, be stored under the current path, pass to workstation by communication module.
Intelligent analysis module exists with the dynamic base form, and its calling interface is:
int?analysis_waveform(const?char*file)；
