摘要:

针对多功能电子系统射频任务的电磁兼容问题,在分析电磁干扰原因的基础上,建立了任务调度的电磁兼容层次分析模型,设计了多功能电子系统电磁兼容任务调度算法,算法采用空域、频域、时域多维层次分析方式,有效地实现了任务间的电磁兼容。最后分析了算法的任务结束时间和任务丢失率,并与传统的任务调度算法进行了比较分析,结果表明,文中设计的电磁兼容调度算法,在解决任务调度电磁兼容问题上具有一定的有效性和优越性。

Abstract:

In this paper,an algorithm for electromagnetic compatibility task scheduling is proposed to solve the electromagnetic compatibility problem of radio-frequency head in multifunctional electronic system,based on the analysis of electromagnetic compatibility and the constructed mathematical mode.The algorithm adopts multidimensional managing mode including air area,frequency area and time area to realize the goal of electromagnetic compatibility between tasks.In addition,the task losing proportion is analyzed and simulated.The result shows that the proposed algorithm is valid and efficient.

Key words: multifunctional electronic system;EMC;priority;time window
