传统船舶电力系统在使用过程中,存在低功耗电子电路故障识别准确度低的问题,因此,提出船舶电力系统低功耗电子电路故障准确获取系统。首先针对问题产生原因进行分析;其次,针对原因创建微电子检测识别硬件,对低功耗电路状态进行针对性检测;接着,引入混沌故障算法对低功耗电路内的异常故障因子进行混沌计算,得出故障混沌值,完成故障识别;最后,通过仿真实验的方式,对比设计系统与传统系统的识别效果,以此证明设计系统的有效性与可行性。 相似文献

On the basis of the Bayesian principle, a method of selecting the double beta distribution as a priori distribution is proposed for the system reliability evaluation when the available field test samples are small for pyrotechnic device. Under the condition of different field and historical data, the mean square error(MSE) and coverage ratio(CR) of the reliability evaluation are compared by numerical simulation when the conjugate distribution and uniform distribution are selected as the priori distribution. Finally, the rationality and engineering applicability of the proposed method are verified through an example of the reliability evaluation of a typical pyrotechnic device. 相似文献
