本发明实施例涉及数据分析技术领域，尤其涉及一种AE300航空发动机事件记录文件解析方法及设备。The embodiments of the present invention relate to the technical field of data analysis, and in particular, to a method and device for parsing an AE300 aero-engine event record file.
背景技术Background technique
AE300系列发动机是Austro Engine公司生产的航空用活塞式航煤发动机。其采用电子式高压共轨技术，四缸直列压燃式，经济省油，动力充足，整个发动机的运转和控制靠EECU(发动机电控单元)完成，EECU在控制发动机过程中会实时记录发动机的运转数据，同时会记录发动机发生的“事件信息”，比如：事件7697代表发动机超转、事件7171代表螺旋桨调速器卡阻。这些事件对于发动机的健康管理十分重要，可以连续监测某段时间内某个事件的发生频率的变化，可以在一定程度上代表发动机当前的运转超限趋势。Austro Engine公司提供的AE300 Wizard软件可以读取EventRec文件，但是只能在其简陋的事件列表上查看事件，而无法导出事件，进行更深层次的分析和处理，无法实现大规模机队的发动机健康管理。因此，开发一种AE300航空发动机事件记录文件解析方法，可以有效克服上述相关技术中的缺陷，就成为业界亟待解决的技术问题。The AE300 series engine is an aviation piston jet fuel engine produced by Austro Engine. It adopts electronic high-pressure common rail technology, four-cylinder in-line compression ignition, economical and fuel-efficient, and sufficient power. The operation and control of the entire engine are completed by EECU (engine electronic control unit), which will record the operation of the engine in real time during the control of the engine. At the same time, the "event information" of the engine will be recorded, such as: event 7697 represents the engine overrun, event 7171 represents the propeller governor jamming. These events are very important for the health management of the engine. The frequency of an event can be continuously monitored for a certain period of time, which can represent the current running overrun trend of the engine to a certain extent. The AE300 Wizard software provided by Austro Engine can read EventRec files, but it can only view events on its simple event list, but cannot export events for deeper analysis and processing, and cannot achieve large-scale fleet engine health management . Therefore, the development of an AE300 aero-engine event record file parsing method can effectively overcome the above-mentioned defects in the related technologies, which has become an urgent technical problem to be solved in the industry.

基于上述方法实施例的内容，作为一种可选的实施例，本发明实施例中提供的AE300航空发动机事件记录文件解析方法，所述第一状态节点为ECU A的数据组状态，所述第二状态节点为ECU B的数据组状态。具体地，读取事件记录文件xmlns为A或B的STATUS节点(即第一状态节点或第二状态节点)，A和B分别代表EECU中ECU A与ECU B的数据组状态，其ENTRY_CNT属性(即预定属性)大于0，则继续解析，否则认为事件记录文件(EventRec文件)内没有发动机运行数据，解析结束。继续读取xmlns属性为A或B的SECTORS节点(即第一扇区节点集或第二扇区节点集)，A和B分别代表EECU中ECU A与ECU B，依次读取其各个SECTOR子节点，SECTOR节点的ID子节点的内容为扇区ID，SECTOR节点的DATA子节点为扇区数据，每扇区65538个字节。每个扇区起始两个字节为固定，分别为0x61与0xF6，其最末尾4个字节为扇区类型，共6种类型，其含义及是否需要解析见表1。Based on the content of the above method embodiment, as an optional embodiment, in the method for parsing the AE300 aero-engine event record file provided in the embodiment of the present invention, the first state node is the data group state of ECU A, and the first state node The two-state node is the data group state of ECU B. Specifically, the read event record file xmlns is the STATUS node of A or B (ie the first state node or the second state node), A and B respectively represent the data group states of ECU A and ECU B in the EECU, and their ENTRY_CNT attributes ( That is, the predetermined attribute) is greater than 0, then continue parsing; otherwise, it is considered that there is no engine running data in the event record file (EventRec file), and parsing ends. Continue to read the SECTORS node whose xmlns attribute is A or B (that is, the first sector node set or the second sector node set), A and B respectively represent ECU A and ECU B in EECU, and read their respective SECTOR child nodes in turn , the content of the ID sub-node of the SECTOR node is the sector ID, and the DATA sub-node of the SECTOR node is the sector data, each sector is 65538 bytes. The first two bytes of each sector are fixed, which are 0x61 and 0xF6 respectively. The last 4 bytes are the sector type, and there are 6 types in total. See Table 1 for their meanings and whether they need to be parsed.
表1Table 1
基于上述方法实施例的内容，作为一种可选的实施例，本发明实施例中提供的AE300航空发动机事件记录文件解析方法，所述预定区间为[0,15]和[140,154]。Based on the content of the above method embodiment, as an optional embodiment, in the method for parsing the AE300 aero-engine event record file provided in the embodiment of the present invention, the predetermined interval is [0, 15] and [140, 154].

具体地，在表1的基础上，将扇区ID在[0,15]和[140,154]区间内(即预定区间)，且其扇区类型为Locked、Active、Unknown类型的扇区(即预定扇区类型)中第2个字节(首个字节索引定义为0)至第65533个字节(定义为扇区有效载荷)，按照扇区ID从小到大依次存入字节数组D1(即第一字节数组)中，则各扇区有效载荷首字节在字节数组D1中的存放索引分别为T0、T1、T2…Tn。则对于n>＝1，有(Tn)-(Tn-1)＝65532。进一步地(对应于步骤102)，若扇区类型为Active的扇区，则记录其扇区有效载荷首字节在字节数组D1(即第一字节数组)中的索引为Tx(即第一索引)，D1数组的总长度为m，则D1数组中索引从Tx+63352至Tm-1范围(即第一预定范围)内的字节依次拷贝至字节数组D2数组(即第二字节数组)索引范围为0至m–Tx–65532-1(即第二预定范围)的字节中，将D1数组中索引从0至Tx+65532–1(即第三预定范围)的字节依次拷贝至D2数组中索引范围为m–Tx–65532至m-1的(即第四预定范围)字节中。清空D1数组(即第一字节数组)，完整拷贝D2数组至D1数组中。Specifically, on the basis of Table 1, the sector ID is in the interval [0,15] and [140,154] (that is, a predetermined interval), and its sector type is a sector of type Locked, Active, and Unknown (that is, a predetermined interval). The second byte (the first byte index is defined as 0) to the 65533rd byte (defined as the sector payload) in the sector type) are stored in the byte array D1 ( That is, in the first byte array), the storage indices of the first byte of the payload of each sector in the byte array D1 are T0, T1, T2...Tn respectively. Then for n>=1, (Tn)-(Tn-1)=65532. Further (corresponding to step 102), if the sector type is Active, record the index of the first byte of its sector payload in the byte array D1 (that is, the first byte array) as Tx (that is, the first byte array). One index), the total length of the D1 array is m, then the bytes in the index range from Tx+63352 to Tm-1 (ie the first predetermined range) in the D1 array are sequentially copied to the byte array D2 array (ie the second word). section array) in the bytes whose index range is 0 to m–Tx–65532-1 (ie, the second predetermined range), the bytes in the D1 array whose index is from 0 to Tx+65532–1 (ie, the third predetermined range) They are sequentially copied to the bytes in the D2 array whose index ranges from m-Tx-65532 to m-1 (ie, the fourth predetermined range). Clear the D1 array (ie, the first byte array), and copy the D2 array completely to the D1 array.

Specifically (corresponding to step 103), starting from the index m-1 (ie the second index) of the D1 array (ie the first byte array), and searching forward, if it is found that 12 consecutive bytes starting from the index Mx satisfy Mx- The lower eight bits of the sum of bytes from 11 to Mx-1 are equal to the byte with index Mx, and 0<=byte with index Mx-11<165, 1<=byte with index Mx-10<= 12, 1 <= byte at index Mx-9 <= 31, 0 <= byte at index Mx-8 <= 23, 0 <= byte at index Mx-7 <= 59, 0 <= The byte with index Mx-6 <= 59, and the upper 5 bits of the byte with index Mx-3 must be all 0, then the 12 consecutive bytes from Mx onward are considered to be an "event group".
