摘要
搭建激光供能系统,通过光纤进行高电位和低电位数据通信和能量传输,具有良好的抗干扰能力和稳定性。最近,在多应力条件下半导体器件老化问题受到较大关注。单应力法在设计阶段和老化研究中相对简单,但不适合多应力的实际工作条件。现有的多应力老化研究大多基于电子元器件,并未研究整个系统的可靠性。基于Arrhenius模型、逆幂率模型及尼尔森的广义对数线性模型建立激光供能系统的多应力寿命预估模型,该模型根据不同的温度应力和电压应力,得到实际的可靠度曲线,预估出整个激光供能系统的可靠度,根据可靠度来确定系统的零件更换时间,完成零件的及时更换,确保长期高效的工作,避免由零部件损坏带来的突发状况。
The laser energy supply system was built to carry out high potential and low potential data communication and energy transmission through optical fiber,which has good anti-interference ability and stability.Recently,the aging problem of semiconductor devices under multiple stress conditions has received greater attention.The single stress method is relatively simple in the design stage and aging research,but it is not suitable for actual working conditions with multiple stresses.Most of the existing researches on multi-stress aging are based on electronic components and have not studied the reliability of the entire system.Based on Arrhenius model,inverse power law model and Nielsen's generalized logarithmic linear model,the multi stress life prediction model of laser energy supply system was established.The model obtained the actual reliability curve according to different temperature stress and voltage stress,and predicted the reliability of the entire laser energy supply system.According to the reliability,the system parts replacement time was determined,the timely replacement of parts was completed to ensure long-term and efficient work and to avoid the sudden situation caused by parts damage.
