Most cloud model generators are based on pseudorandom number. With the research of the development situation of random-number generator and cloud model at home and abroad, this paper designs a high-quality-random number-producing hardware project and uses the software solution to gradually convert the uniformly distributed true random sequence into an one-dimensional cloud model of normally distributed true random numbers. It disscusses in depth about the implementation of cloud model generator based on true random numbers. It is the first time in our country and is helpful to the study of cloud model.
