Abstract

The embodiment of the invention provides an AE300 aero-engine data log file analysis method and equipment. The method comprises the steps of obtaining a first electronic control unit state node or a second electronic control unit state node of xmlns attributes in a data log file; obtaining a first index of an Active type sector in a predetermined sector type in a first byte array; and searching forwards from a second index of the updated first byte array, and if the length of twenty-five consecutive bytes of the discoverer is zero, marking each pair of LeadInX and LeadOutX, and indexing bytesfrom LeadInX + 1 to LeadOutX-32, and the like. According to the AE300 aero-engine data log file analysis method and equipment provided by the embodiment of the invention, complete analysis of the datalog of an AE300 aero-engine can be realized.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of data analysis, in particular to a method and equipment for parsing data log files of an AE300 aeroengine. Background technique [0002] The AE300 series engine is an aviation piston aeroengine produced by Austro Engine. It adopts electronic high-pressure common rail technology, four-cylinder in-line compression ignition type, economical and fuel-efficient, and has sufficient power. The operation and control of the entire engine are completed by EECU (Engine Electronic Control Unit). EECU will record the operation of the engine in real time during the process of controlling the engine. Data, including 16 kinds of signal data including propeller speed, intake pressure, intake temperature, engine power, common rail pressure, low-pressure fuel pressure, etc., are recorded, which are very important for engine fault diagnosis and health management. Although Austro Engine provides its ...
