Embodiment Construction

[0039] In order to ensure the applicability of the method, the present invention provides an overall structural diagram of the realization of the method. The method will be further described in detail in conjunction with the accompanying drawings and implementation examples.

[0040] The specific implementation manner will be introduced below taking the data file of the iNet format protocol as an object.

[0041] Implementation object description: The iNet format is a typical data format in work data collection. Its structure is mainly composed of mac header, ip header, UDP header, iNet header, and data source code. In the ip header, you can read the length of a single packet, the data The sending source address, the data receiving source address, etc. can be read in the iNet packet header. The streamID (indicating the channel number of the current data collected by the collector, used to determine which parameters are currently collected and the position of the parameters), th...

Abstract

The invention discloses a rapid processing method of mass sensor test data of aircrafts, comprising the following steps: 1) acquiring the original parallel data transmitted by an aircraft sensor, cutting the parallel data to generate a plurality of raw packets, and uploading to an HDFS file; 2) carrying out data analysis of the raw packets to obtain the standardized data after time alignment; 3) Exporting the standardized data after time alignment to generate the line data, and distributing the data of each column into each computer of the Spark cluster for distributed computation. The methodof the invention can reduce the data communication between the distributed computing clusters as much as possible, and all threads can share the same resources in the case of noninterference from eachother, thereby remarkably improving the data processing speed; In addition, the method of the invention can improve the efficiency of the test data processing of aircrafts and shorten the time interval between two tests.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a rapid processing method for mass sensor test data of an aircraft. Background technique [0002] The aircraft needs to go through a lot of tests to ensure the normal and stable operation of the equipment from the integration of components to the official operation. With the rapid development of national defense work, the integration of aircraft is getting higher and higher, and the number of airborne sensors is significantly increasing. This leads to The types of parameters and the amount of data in the test data have greatly increased. Taking a single test of a typical civil aircraft as an example, there are currently tens of thousands of parameters involved, and the generated data is about 150GB. The scale of data processing is already very large. [0003] At present, for the data downloaded by airborne sensors, there are mainly two existing data processing methods accordin...
