A kind of network data packet analysis and distribution method

Abstract

The invention relates to a network data packet analyzing and distributing method and belongs to the technical field of helicopter comprehensive experiment testing communication. The method comprises the steps of: firstly receiving a data packet from a data collection server; judging whether the received data packet has a frame head and a frame tail, and carrying out splicing and forming a complete data packet; generating a one-dimensional array A with channel identifiers in the complete data packet; generating a one-dimensional array B with channel identifiers, corresponding to data needed by a client end, in the one-dimensional array A; according to the channel identifiers in the one-dimensional array B, obtaining data, corresponding to the channel identifiers, in complete frames, then combining the data with the channel identifiers to generate single-channel one-dimensional arrays C1-Cn, placing the n single-channel one-dimensional arrays into a queue, and simultaneously, carrying out equal-proportion zooming in the queue according to a proportion relation between sampling time and required time; and exporting the processed single-channel one-dimensional arrays from the queue, and processing and displaying the processed single-channel one-dimensional arrays by the client end.

Description

technical field [0001] The invention belongs to the technical field of helicopter comprehensive test test communication, and in particular relates to a method for analyzing and distributing network data packets. Background technique [0002] Helicopter comprehensive test is an important stage in the process of helicopter development. At present, comprehensive test includes rotor system test, ground joint test, wind tunnel test, anti-icing test, etc. The characteristics and difficulties of the comprehensive test include: multiple types of test parameters, multiple test channels, wide range of data sampling rates, and diverse data processing requirements. The method is developed based on the test requirements of the joint ground test, and the design goal is to design a distributed general test system based on the network. To achieve this goal, it is not only necessary to fully consider the characteristics and difficulties of the system in terms of hardware selection and integ...

Problems solved by technology

[0004] (1) Previously, the dedicated network data packet formats provided by each hardware supplier were used, resulting in different network data packet formats for different types of parameters, which increased the difficulty and workload of network data analysis, and the analysis efficiency was also low;

[0005] (2) The traditional network data packet analysis method adopts the form of caching the data of multiple channels into a multidimensional array, which is not suitable for data packets containing multiple sampling rates;

[0006] (3) The traditional data analysis and distribution module design does not fully consider the versatility of the module, and it is difficult to directly transplant the module to other test bench test software
