The AE300 aeroengine event log file parsing method of claim 1, wherein the predetermined interval of the index Mx comprises: byte <165,1 > with index Mx-11 0 ≦ byte ≦ 12,1 ≦ byte ≦ 31,0 ≦ byte ≦ 23,0 with index Mx-8 of byte ≦ 59,0 of index Mx-7 of byte ≦ 59,0 of index Mx-6 of byte ≦ 59, and byte upper five bits with index Mx-3 are all 0.
5. The AE300 aeroengine event log file parsing method of claim 1, wherein the predetermined attribute is an ENTRY _ CNT attribute.
6. The AE300 aeroengine event record file parsing method of claim 1, wherein the bytes of the predetermined range segment are second byte to 65533 bytes.
7. An AE300 aeroengine event record file analysis device is characterized by comprising the following components:
a sector information obtaining module, configured to obtain a first state node or a second state node in an xmlns attribute in an event record file, and if a predetermined attribute of the first state node or the second state node is not zero, obtain a first sector node set or a second sector node set in the xmlns attribute, and sequentially obtain a sector ID and sector data of each sector node in the first sector node set or the second sector node set;
the byte copying module is used for sequentially storing bytes of a preset range section in a sector with a sector ID in a preset interval and a sector type of a preset sector type into a first byte array from small to large according to the sector ID, if the sector type is an Active sector type, acquiring a first index of the Active sector type in the first byte array, copying the bytes of the first preset range in the first byte array into the bytes of a second preset range in a second byte array according to the first index, copying the bytes of the third preset range in the first byte array into the bytes of a fourth preset range in the second byte array, emptying the first byte array, and copying contents in the current second byte array into the emptied first byte array to obtain an updated first byte array;
an event group defining module, configured to search forward from the second index of the updated first byte array, and if the lower eight bits of the twelve consecutive bytes from the index Mx, which satisfy the sum of the bytes of the indexes Mx-11 to Mx-1, are equal to the byte of the index Mx and satisfy a predetermined interval of the index Mx, define the first twelve consecutive bytes with the index Mx as the starting point as an event group;
the complete analysis module is used for continuously analyzing the event record file according to the mode of obtaining the event group until the index Mx is zero;
the first state node is the data group state of the ECUA, and the second state node is the data group state of the ECU B.
8. An electronic device, comprising:
at least one processor, at least one memory, and a communication interface; wherein the content of the first and second substances,
the processor, the memory and the communication interface are communicated with each other;
the memory stores program instructions executable by the processor, the processor invoking the program instructions to perform the method of any of claims 1 to 6.
9. A non-transitory computer-readable storage medium storing computer instructions for causing a computer to perform the method of any one of claims 1 to 6.
