Design of true random number cloud model generator based on LabVIEW

云发生器是构造云模型不确定性推理和设计云模型智能控制器的基础,全面论述了一种基于硬件真随机数云发生器的实现方法。首先设计一种基于雪崩噪声电路产生的真随机数序列发生器,利用LabVIEW平台构建测试系统对其进行一系列特性检验,进而将该真随机数序列转换为正态分布的真随机数作为云发生器的随机数源,最后设计一种真随机数云发生器算法,并通过LabVIEW平台编程实现。实验结果表明,该真随机数云发生器生成结果十分理想,可为云模型不确定性推理后续研究提供基础。

Cloud generator （C（;） makes the foundation of structuring uncertainty reasoning of cloud model （CM） and designing CM intelligent controller. This paper comprehensively expounds a method of realizing CG based on hardware true random number （TRN）. First,the paper designs a TRN sequence generator based on avalanche noise circuit,and makes its identity test through LabVIEW platform;then transforms this TRN sequence into normal distributed TRN as the source of C（;,;at last designs an algorithm of TRN CG and implements it by programming on I.abVIEW platform. The experiment shows that TRN CG- produces an ideal result, providing a basis for follow-up study on uncertainty reasoning of CM.
