Research on Data Transmission Delay Compensation of Avionics Communication Network under Complex Working Conditions
To address the issues of significant environmental noise interference and excessive data transmission delay in avionics communication network under complex working conditions,this paper investigates the data transmission delay compensation of avionics communication network under complex working conditions.Nonlinear transformation algorithms are used to analyze the data status of the communication network,and determine the discrete values and linear changes that affect the delay fac-tors.A data transmission delay status model is established to analyze the real-time status of each node,calculate the data trans-mission status and delay parameters,and solve their interrelationship.The problem of data transmission delay is abstracted as a first-come-first-served queuing service,and the relationship among data transmission rates,arrival rates and delay time is cal-culated.Based on this,the real-time delay values at the maximum time point are determined,and the difference filling process is performed in the order of delay priority to achieve data transmission delay compensation.The results show that the proposed method has good compensation accuracy and effectiveness,reduces the delay time in avionics communication and enables real-time command reception and message transfer capabilities,which indicates the practical value of the proposed method.
