Data Parallel Processing And Task Scheduling Method Of Minefield Synchronous Detection

A minefield is a specific area formed by the presence of explosives such as mines surface or underground.The development of a safe,efficient and accurate minefield detection system has great national defense application value.Aiming at the limitations of low detection efficiency and poor safety of the traditional individual mine detection system,the vehicle mine detection system can not enter the minefield area with dense vegetation and complex terrain,and the low detection accuracy of the existing low altitude mine detection system,a synchronous detection scheme based on one detection control host and N detection extensions with flight function is proposed,and a multi-source information synchronous detection system for minefield is developed in this thesis.Considering the particularity of minefield multi-source information detection,multiple task categories and large amount of data,the research of data parallel processing and task scheduling method suitable for minefield detection have great application value.This thesis main research contents are as follows:(1)According to the minefield task of synchronous detection,the synchronous detection method of minefield is proposed.The overall scheme of the system,the hardware circuit and software program are designed.The frame synchronization detection of the detection control host and each detection extension is realized.The byte synchronization and bit synchronization of single-core control multi-channel data acquisition are realized.(2)In view of the real-time requirements of minefield synchronous detection data,a parallel processing method of minefield detection data based on multi-core DSP is proposed aiming at the algorithm that requires parallel data processing in minefield detection.The parallel acquisition and storage space optimization of minefield detection data is realized.The computational accuracy and real-time nature of parallel processing method are verified by experiment.(3)The data processing task of synchronous detection of minefield is analyzed,and the multi-core multi-task model of minefield is constructed.The adaptive task scheduling method of ant colony parameters is proposed.The task transfer rules and core transfer rules are improved.The parameter adaptive tuning rules are designed,and the effectiveness of the adaptive adjustment strategy is verified by experiment.(4)The minefield detection system test is carried out in the test site.The parallel processing and task scheduling method of minefield synchronous detection data are experimentally verified.The influence of different data quantities on the parallel processing performance of multi-core DSP is analyzed,so as to achieve the highest parallel operation efficiency and shorten the overall execution time of the parallel processing task of minefield data.
